What CoconutBattery Brings to macOS Users
CoconutBattery for Mac: The Friendly Way to Keep an Eye on Your Battery Health
You plug in your MacBook and open CoconutBattery to see exactly how much charge the battery holds compared with when it was new. CoconutBattery for Mac is a lightweight utility that reads the battery’s current capacity, design capacity, cycle count, and health percentage alongside live charging and power draw data. It also tracks battery health over time and can display the status of connected iOS devices, making it easy to judge whether a battery is aging normally or nearing replacement.
What CoconutBattery Brings to macOS Users
CoconutBattery gives macOS users a dead-simple way to see the real health of their MacBook battery, showing current charge capacity next to the original design capacity so you know how much wear has built up over time. It also displays cycle count, battery temperature, and charging status in one clean window. Why do people install it? Because macOS’s built-in tools don’t show design capacity side by side with current capacity, and seeing that percentage makes it easy to judge whether a battery is aging normally or needs replacement. It also tracks your iPhone and iPad battery stats when connected, making it a handy all-in-one checker for Apple gear.
Real-time battery health monitoring at a glance
CoconutBattery places live battery data directly in the menu bar, so real-time battery health monitoring at a glance requires no window switching or manual refreshes. The current charge percentage, charging status, and remaining time update continuously as conditions change. Opening the dropdown reveals the battery’s present capacity alongside its original design capacity, letting you judge degradation the moment you look. A color-coded indicator marks whether health sits in a healthy range or has declined, turning raw numbers into an instant read. This persistent, always-visible feedback makes it practical to spot abnormal drain or charging behavior during everyday use rather than discovering problems after the fact.
Why MacBook owners rely on detailed charge data
MacBook owners rely on detailed charge data because Apple’s menu bar battery icon only shows a rough percentage, which hides the real story of battery health. With detailed charge data in coconutBattery, users can see exact current capacity, design capacity, and charge cycles in one place. That visibility helps them judge whether a used Mac is worth buying, confirm if a replacement battery was actually installed, or spot a rapid capacity drop before it becomes a costly problem. Instead of guessing why runtime feels shorter, they can compare full charge capacity against the original design and decide whether to recalibrate, service, or replace the battery.
Key metrics displayed by the utility
CoconutBattery puts the numbers that matter most right on screen, starting with the live battery charge level and real-time power draw that show exactly how much energy your Mac is using at any moment. It displays the current capacity against the original design capacity, giving you a clear percentage of remaining battery health rather than a vague guess. You also see the battery’s cycle count, temperature, and charging status, plus detailed voltage and amperage readings for each connected power source. These metrics update continuously, so you can spot degradation, confirm a charger is delivering full wattage, or diagnose unexpected drain the instant it happens.
Installing the Battery Diagnostic Tool on Your Mac
I remember staring at my aging MacBook, wondering why the battery drained so fast, and a friend said, “Just grab coconutBattery.” So I went to the official site and downloaded the DMG, then dragged the coconutBattery icon into my Applications folder. On first launch, macOS asked me to confirm opening an app from the internet, and after clicking Open, the tool instantly displayed my battery’s health percentage and cycle count. Here’s what I wish I’d known: “Do I need to install extra drivers?” No—coconutBattery works right out of the box, no kernel extensions or restarts required. That’s the whole process: download, drag, open, and read your battery stats.
Downloading the latest release safely
Get the newest build directly from the official coconutBattery website rather than third-party mirrors, since the vendor page always hosts the current signed release. Confirm the download is a genuine .dmg file and verify the version number matches the latest announcement before opening it. macOS Gatekeeper should show a developer-verified prompt; if it warns about an unidentified developer, stop and re-download instead of bypassing the check. After mounting the disk image, drag the app to Applications and confirm the version in About. Following these steps keeps your download clean and tamper-free.
- Download only from the official coconutBattery site
- Check that the file is a signed .dmg with the expected version
- Never override Gatekeeper warnings for an unknown source
- Verify the installed version after copying to Applications
Granting necessary permissions during setup
When coconutbattery first launches on macOS, Gatekeeper may block it because it was downloaded outside the App Store. To proceed, open System Settings > Privacy & Security, locate the blocked-app notice, and click Open Anyway, then confirm with your administrator password. The tool also requests access to read battery and hardware data; approve this when prompted so it can display health metrics accurately. Granting necessary permissions during setup ensures coconutbattery can query the SMC and report cycle count without repeated prompts. Denying a request once may require manually resetting permissions in System Settings before the app functions fully.
- Click Open Anyway in Privacy & Security after the initial block
- Approve the battery-data access prompt on first launch
- Authenticate with an administrator password when asked
First launch walkthrough and interface tour
When coconutbattery first opens, a brief permissions dialog may appear requesting access to system data; approve it to enable full readings. The main window then displays the first launch walkthrough and interface tour elements: battery health percentage, cycle count, and current charge capacity appear in the top summary panel. Below, the Battery Information tab breaks down design capacity versus actual capacity, while the Temperature and Charging tabs show live power flow. Hovering over any metric reveals a tooltip explaining its meaning. The toolbar lets you switch between This Mac and iOS device views, and the refresh button updates readings manually. Spend a minute exploring each tab to understand where key diagnostics live before relying on the data.
Reading Battery Capacity and Design Specs
In coconutBattery on a Mac, Reading Battery Capacity and Design Specs centers on comparing the current maximum capacity against the original design capacity. The app displays design capacity, current full-charge capacity, and a calculated health percentage, letting you judge how much capacity the battery has lost over time. Switch to the “This Mac” tab to see these figures for the internal battery, and check cycle count alongside them.
A health percentage well below 100% with a high cycle count signals normal aging, while a sudden drop may warrant closer attention.
Note that coconutBattery reports the raw mAh values, so read design capacity as the baseline and current capacity as the measured maximum, not a momentary charge level.
Understanding original design capacity versus current maximum
In coconutBattery, you’ll see two key numbers side by side: the original design capacity your Mac’s battery shipped with and its current maximum capacity. The design capacity vs current maximum comparison is basically a health check—design capacity is the factory benchmark, while current maximum shows what your battery can hold now after wear and tear. A small drop is totally normal over time, but a big gap means your runtime is shrinking. coconutBattery makes this easy to spot at a glance, so you can decide whether it’s just aging gracefully or time to think about a replacement.
Interpreting the health percentage indicator
In coconutBattery for Mac, the health percentage compares current full charge capacity against the original design capacity, so a reading of 85% means the battery now holds 85% of its factory-rated charge. Interpret this figure as a trend rather than a verdict: gradual decline over months is normal, while a sudden drop suggests calibration drift or a failing cell. Values above 100% can appear briefly on new batteries due to capacity variance. Use the health percentage indicator alongside cycle count and age, since a low percentage with few cycles may signal a defective unit rather than ordinary wear.
How cycle counts affect long-term performance
Cycle count is basically how many full charge-discharge rounds your MacBook battery has been through, and coconutBattery shows it right alongside design capacity so you can connect the dots. Each cycle nibbles away at capacity, so a battery at 500 cycles will typically hold noticeably less charge than one at 50, even if both report similar health percentages. Watching cycle count climb in coconutBattery helps you spot **long-term battery wear** before it sneaks up on you. High cycles plus dropping capacity usually means shorter runtime and more frequent charging. How cycle counts affect long-term performance really comes down to this: fewer cycles, slower decline.
Does a high cycle count always mean bad performance? Not always, but combined with falling capacity in coconutBattery, it’s a solid signal your battery’s aging and runtime will keep shrinking.
Monitoring Charging Behavior and Power Flow
Plug in your MacBook and coconutBattery instantly shows whether the adapter is actually feeding the system or merely topping off the battery. Watch the charging wattage and current flow in real time to spot a weak charger or a cable that’s throttling power. The app logs charge cycles and battery age alongside live power draw, so you can see how your habits affect long-term health. Keep an eye on the charge/discharge state indicator to confirm the battery is charging rather than draining under load. Compare adapter wattage against the reported system draw to catch mismatched or failing power supplies. Subtle shifts in current during heavy tasks often reveal more about power delivery than the percentage alone.
Tracking wattage during charge and discharge
Watching the watts go in and out of your MacBook is where coconutbattery really shines. The app shows live charge and discharge wattage right on the main window, so you can see exactly how much power is flowing when the MagSafe or USB-C cable is connected. Unplug and the reading flips to a negative value, revealing your current drain in watts. This makes it easy to spot a weak charger that claims high output but delivers less, or to compare drain while running different apps. Keep an eye on the wattage readout during heavy tasks to judge how hard your battery is working.
coconutbattery’s live wattage display lets you track exactly how much power flows in during charging and out during discharge, helping you verify charger performance and gauge real-time battery drain.
Spotting irregular charging patterns early
Use coconutbattery’s charging history graph to compare daily charge cycles and flag any deviation from your normal routine the moment it appears. Watch for sudden drops in maximum capacity, charge levels that stall below 100%, or repeated top-ups at unusual times, since these often precede deeper battery issues. Spotting irregular charging patterns early lets you correlate odd behavior with recent app usage, cable changes, or adapter swaps before damage compounds. Because the history view preserves timestamps, even a single anomalous session stands out against weeks of consistent data. Check the graph weekly so subtle shifts never go unnoticed.
Early detection of irregular charging patterns in coconutbattery turns small anomalies into actionable warnings before they become costly battery failures.
Battery temperature insights for daily use
Keeping an eye on your MacBook’s battery temperature in coconutBattery is a simple habit that pays off daily. A comfortable range—roughly 10–35°C—means your battery isn’t stressed while charging or under heavy load. If you notice readings climbing during video calls or big exports, give your Mac some airflow and skip charging until things cool down. coconutBattery’s live temperature readout makes it easy to spot when your battery temperature insights for daily use are telling you to ease off. Watch for sustained heat above 35°C, since that’s when long-term wear speeds up.
- Check temperature before and during charging to catch heat spikes early.
- Avoid charging right after heavy tasks until the battery cools.
- Keep vents clear and use a hard surface for better airflow.
Using Historical Data to Assess MacBook Longevity
coconutBattery’s history view transforms a single battery reading into a longevity signal by logging charge capacity, cycle count, and age over time. Export that data and chart design capacity against current maximum capacity to see degradation rate, not just today’s percentage. A steady decline near expected curve suggests healthy aging; sudden drops after macOS updates or heavy charging habits flag stress. Compare session-to-session readings to catch calibration drift before it skews your assessment. Using historical data to assess MacBook longevity means trusting trends, not snapshots.
Two identical “90% health” MacBooks can have very different futures—only the slope of coconutBattery’s history reveals which one is fading faster.
Review monthly exports to decide whether to keep, service, or replace the battery with confidence.
Exporting logs for trend analysis
coconutBattery lets you save a full history snapshot as a CSV, so you can export battery logs for trend analysis and watch how capacity and cycle count drift over months. Open the CSV in Numbers or Excel, then chart the maximum capacity percentage against charge cycles to spot steady decline versus sudden drops. Since occasional readings can look worse right after a deep discharge, trend analysis works best when you compare exports taken at similar charge levels. Keep a dated export each month in one folder, and you’ll have a clean dataset for judging your MacBook’s long-term health.
Comparing wear across multiple devices
Open coconutBattery on each Mac you own and export the battery health readings side by side to spot which machine is aging fastest. Comparing wear across multiple devices works best when you record design capacity, current maximum capacity, cycle count, and age for every Mac in one table, then calculate the percentage of capacity lost per hundred cycles. A 2019 MacBook Pro at 85% after 400 cycles is wearing more steeply than an M1 Air at 90% after 300 cycles, and coconutBattery’s historical snapshots make that gap obvious. Track the same metrics monthly so outliers stand out.
- Export battery health data from each Mac and align entries by cycle count, not calendar date.
- Calculate capacity loss per 100 cycles for a fair cross-device comparison.
- Flag any device dropping faster than its siblings for closer monitoring.
Deciding when a battery replacement makes sense
Use coconutBattery’s historical charge-capacity and cycle-count logs to distinguish normal aging from actionable decline. A replacement makes sense when full charge capacity has fallen below roughly 80 percent of design capacity and continues trending downward across several recorded sessions, especially if cycle count is near Apple’s rated limit. Corroborate the data with observed behavior: sudden shutdowns under load, capacity dropping sharply after brief use, or swelling. If capacity is stable and runtime still meets your workflow, defer replacement and keep logging. Deciding when a battery replacement makes sense should rest on both sustained data trends and practical symptoms, not a single reading.
Compatibility Across macOS Versions and Apple Hardware
I remember plugging my aging MacBook Air into a friend’s newer Mac and watching coconutBattery light up with the same familiar readouts, which speaks to how broadly the app supports macOS compatibility. coconutBattery runs across a wide range of macOS releases, from older versions still in use on legacy machines to the latest builds on Apple silicon, so the same battery-health interface follows you between systems. On Apple hardware it reads design capacity, cycle count, and current charge on Intel Macs and Apple silicon alike, though some deeper hardware sensor details vary by model and chip. Battery temperature and charge-power readings can differ between Intel and Apple silicon Macs, so compare values against your own model rather than another machine.
Support for Intel and Apple Silicon machines
coconutBattery runs natively on both Intel-based Macs and Apple Silicon models, so you get accurate battery data regardless of which chip powers your machine. On Apple Silicon, the app reads the same health, cycle count, and charge capacity metrics it reports on Intel hardware, without relying on Rosetta translation. Support for Intel and Apple Silicon machines means a single download works across both architectures. Installation follows the same straightforward steps on either platform, so you never need a separate build or special configuration.
Behavior on older MacBooks and macOS releases
On older MacBooks running legacy macOS releases, coconutBattery often requires specific builds to maintain accurate readings, as newer versions may drop support for deprecated APIs used by earlier hardware. Battery health reporting on older macOS versions can vary: some pre-2011 models expose limited cycle count or design capacity data, causing coconutBattery to display partial or estimated values rather than full diagnostics. Users on macOS 10.6–10.12 may need to select an older coconutBattery release to avoid launch failures or missing sensor data. Additionally, older MacBooks with removable batteries sometimes report inconsistent temperature or charge metrics, which coconutBattery reflects without correction.
- Older macOS releases may require legacy coconutBattery versions for sensor access.
- Pre-2011 MacBooks often show partial battery data due to limited hardware reporting.
- Removable-battery models can display inconsistent temperature or charge readings.
Known limitations worth knowing
coconutbattery has known limitations worth knowing before you rely on its readings. On Apple Silicon Macs, some battery health and cycle count data may appear inconsistently because the app depends on firmware-reported values that vary by chip generation. Older Intel models can show inaccurate maximum capacity figures after macOS updates change how battery data is exposed. The iOS device battery info view requires a wired connection and does not work over Wi-Fi, and some iPhone models report only partial details. Temperature and charge current readings refresh slowly on certain hardware, and the app cannot access battery data from devices paired but not physically connected. These gaps mean coconutbattery is best treated as a convenient reference, not a diagnostic authority.
Everyday Tips for Healthier Laptop Batteries
Use coconutBattery on Mac to monitor your battery’s health and charge cycles regularly, so you catch degradation early and adjust habits accordingly. Avoid leaving your MacBook plugged in at 100% for long stretches; coconutBattery’s live charge readout helps you unplug around 80% during desk use. Keep the machine cool, since heat accelerates wear and coconutBattery’s temperature display lets you spot overheating during heavy tasks. Calibrate occasionally by running it down and recharging fully, then confirm the reported capacity in coconutBattery.
Treat coconutBattery’s health percentage as your feedback loop: small habit changes show up there within weeks.
Store the laptop at roughly 50% charge for extended periods, verified via coconutBattery before shutdown.
Charge habits that slow chemical aging
Keep your MacBook in the 20–80% range whenever practical, since lithium-ion cells age fastest at extreme states of charge. Avoid leaving the laptop plugged in at 100% for long stretches; partial discharges and recharges reduce the chemical stress that degrades capacity over time. Enable optimized charging so macOS learns your routine and delays full charge, and use coconutBattery to watch how your habits affect the battery’s health percentage over weeks. Heat accelerates chemical aging, so charge in a cool, ventilated spot and avoid charging during heavy workloads. Slower charging habits directly extend battery lifespan by minimizing the time your cells spend at high voltage.
Temperature management during heavy workloads
When you’re rendering video or compiling code, your Mac’s battery heats up fast, and that heat is the real enemy of long-term battery health. Use coconutbattery to watch the battery temperature reading while you work, and if it climbs past roughly 35°C, take a short break or move to a hard, ventilated surface so airflow can do its job. Temperature management during heavy workloads also means skipping soft surfaces like beds and cushions that trap heat around the chassis. If a laptop cooling pad is handy, it’s a cheap way to keep things chill during marathon sessions. Closing unused apps reduces sustained load and the heat that comes with it.
Keep heavy tasks short, stay on hard surfaces with good airflow, and monitor battery temperature in coconutbattery to protect your battery’s lifespan.
When to calibrate for accurate readings
Calibrate only when coconutBattery shows readings that conflict with real-world behavior, such as a full charge draining unusually fast or a shutdown near 20 percent. A full battery calibration is warranted after replacing the battery, after long periods mostly plugged in, or whenever the reported maximum capacity looks erratic. To calibrate:
- Charge to 100 percent and keep it plugged in for two hours.
- Unplug and run the Mac on battery until it sleeps.
- Leave it off for five hours, then recharge to 100 percent.
Calibrating more than every few months adds wear without improving accuracy. Rely on coconutBattery to confirm the readings stabilize afterward.
Comparing CoconutBattery With Built-in macOS Tools
CoconutBattery for Mac offers battery health metrics beyond what macOS’s built-in System Information provides, including original design capacity, current maximum capacity, and cycle count in a single view. While macOS reports basic condition status such as “Normal” or “Service Recommended,” CoconutBattery displays precise milliampere-hour values and a percentage-based health estimate that updates with each reading. The app also tracks battery temperature and charge behavior over time, details absent from Apple’s native tools. For users comparing multiple batteries or monitoring degradation across sessions, CoconutBattery’s historical logging adds context that System Information cannot retain. It is worth noting that macOS’s built-in reporting remains sufficient for casual checks, since it draws directly from the same hardware sensors. Neither tool replaces proper calibration, but CoconutBattery presents the raw data in a more detailed, exportable format.
What System Information misses
System Information reports battery condition as a simplified label and omits the raw data CoconutBattery exposes. It does not show actual battery capacity in mAh alongside the original design capacity, so you cannot calculate precise wear percentage yourself. Cycle count appears, but charge level history, current amperage, and voltage readings during use are absent. System Information also hides temperature and power adapter wattage details that CoconutBattery displays live. Without these metrics, users cannot track degradation trends over time or verify whether a replacement battery meets its rated specification.
System Information omits raw capacity figures, live electrical readings, temperature, and adapter wattage, leaving users unable to measure precise battery wear or verify replacement specs.
Extra detail versus native battery menu options
The macOS battery menu shows only charge percentage and basic condition, while CoconutBattery exposes granular metrics the native menu omits entirely. Where the menu reports a single health figure, CoconutBattery displays design capacity, current full charge capacity, cycle count, temperature, and instantaneous wattage side by side. This extra detail versus native battery menu options distinction matters when diagnosing degradation: the menu flags “Service Recommended” without explaining why, whereas CoconutBattery lets you correlate capacity fade with charge cycles and thermal history. The native menu updates intermittently; CoconutBattery refreshes live, making short-term power draw visible. For users tracking aging across months, the menu’s snapshot suffices; for pinpointing anomalies, CoconutBattery’s depth replaces guesswork with measurable evidence.
Choosing the right tool for casual versus power users
Casual users who just want a quick battery health percentage are best served by the built-in macOS tools, since the menu bar indicator and System Settings deliver that answer without extra installation. Power users, however, should reach for CoconutBattery because it exposes charge cycles, design capacity, temperature, and voltage history that macOS hides. The deciding factor is choosing the right tool for casual versus power users based on how deep the diagnosis needs to go. If you only check health occasionally, stay native; if you troubleshoot degradation, calibrate packs, or track a machine over time, CoconutBattery earns its place.
Privacy, Safety, and App Trustworthiness
You plug in a dying MacBook, launch coconutbattery mac, and it instantly reads your battery’s health—no account, no cloud sync, no background telemetry. That local-only design is its quiet privacy win: the app queries hardware through macOS’s I/O Kit rather than phoning home, so cycle counts and capacity stay on your machine. Safety matters too, because coconutbattery only reads system data and doesn’t request admin rights or install kernel extensions, limiting its footprint. Trustworthiness hinges on verifying you downloaded it from the developer’s official site, since copycat builds could bundle unwanted code. Still, a tool that merely reports battery wear deserves scrutiny only if it asks for permissions beyond that narrow job.
Data handling practices of the developer
coconutBattery performs its core readings locally, so the developer’s data handling practices matter mainly when the app contacts the network. The developer states that no personal data is collected or transmitted during normal battery monitoring, and that hardware details remain on the Mac. When you use the optional online battery comparison feature, limited technical values such as model identifiers and charge statistics are sent to the developer’s server to return aggregated coconutbattery checker results. The practical distinction is that offline use keeps all readings local, while the comparison feature requires a deliberate opt-in.
- Check whether online comparison is enabled in preferences.
- Review what technical values the feature submits.
- Disable the feature if local-only operation is preferred.
Verifying signatures and avoiding fake downloads
Always download coconutbattery mac from the official coconut-flavour.com website rather than third-party mirrors or search ads that may bundle modified installers. After downloading, right-click the app and choose Open to inspect the Gatekeeper prompt, confirming the developer is coconut-flavour.com and not an unidentified source. Verifying signatures with codesign in Terminal, such as codesign -dv –verbose=4 /Applications/coconutBattery.app, confirms the bundle ID and signing authority match the official release. Check that the notarization ticket is present using spctl -a -vv, which shows whether Apple has verified the build. Avoid fake downloads promoted through unofficial sites, and never bypass Gatekeeper warnings for this utility.
How can I confirm a coconutBattery download is authentic? Verify the developer signature and notarization status with codesign and spctl before launching, and download only from the official site.
Community reputation and update cadence
coconutBattery’s long-standing user community and predictable release rhythm are central to its trustworthiness. The app has been discussed for years in Mac forums, where users consistently report that battery health readings match Apple’s own diagnostics, and that reputation is reinforced by a steady update cadence rather than sporadic fixes. Developers ship compatibility updates shortly after major macOS releases and patch hardware-detection issues promptly, so users rarely face broken readings for long. This combination of an active, vocal user base and reliable update cadence makes the app feel maintained rather than abandoned. Community feedback also shapes releases: reported bugs and edge cases get acknowledged and addressed in subsequent versions, which strengthens confidence that installing coconutBattery is a low-risk choice for checking battery wear.
Q: How does coconutBattery’s community reputation and update cadence affect my safety as a user?
A: A vocal community quickly flags problems, and regular updates mean fixes arrive fast, so you’re not stuck with outdated or inaccurate battery data.
Frequently Searched Questions About the App
Users frequently ask whether coconutBattery for Mac can show iPhone and iPad battery health, and the answer is yes—connecting a device via cable lets the app display its cycle count and capacity alongside Mac data. Another common question is whether the app works on Apple Silicon Macs, which it does, including native support on M-series models. People also ask if coconutBattery requires an internet connection; most core readings work offline, though some features like battery health history sharing and online comparison require a connection. Common queries also cover how to read the percentage-based health indicator versus the original design capacity, and whether the free version limits certain functions compared with the paid upgrade.
Is it free or does it require a license?
Good news: coconutBattery is free to download and use for personal, non-commercial purposes, so you can check your Mac’s battery health, cycle count, and charging stats without paying anything. The developer does offer a paid license if you want to use it commercially or unlock extra features like saving battery health data over time, but for most folks the free version covers everything they need. Think of it as freeware with an optional upgrade rather than a trial that expires. You won’t hit paywalls or nag screens during normal use, which makes it a low-risk download to try on your Mac.
Can it predict sudden shutdowns?
coconutBattery cannot predict sudden shutdowns because it reports current battery data rather than forecasting future behavior. The app displays live charge capacity, current amperage, voltage, and cycle count, but it does not model how your Mac’s battery will perform under load or when it might cut out unexpectedly. A battery showing low maximum capacity or high cycle count may correlate with sudden shutdown risk, yet coconutBattery presents these as historical and present-state metrics, not predictive warnings. Users hoping for an early alert before an abrupt power loss will not find that function here; the tool supports diagnosis after the fact rather than predicting sudden shutdowns in advance.
Does it work without an internet connection?
Yes, coconutBattery works just fine without an internet connection for its core features. You can check your Mac’s battery health, cycle count, current charge, and capacity completely offline, since the app reads data directly from your device’s hardware. The offline battery monitoring works right out of the box, so no Wi-Fi needed just to see how your battery’s doing. The only time you’ll want a connection is for optional stuff like checking for updates or looking up device info online. Otherwise, you’re good to go anywhere.
Q: Can I use coconutBattery on a plane with no Wi-Fi?
Absolutely—battery readings and health checks all work offline, so airplane mode won’t stop you.
