More About AccuBattery
❤ BATTERY HEALTH
Batteries have a limited lifespan. Every time you charge your device, it wears out the battery, lowering its total capacity.
- Use our charge alarm to remind you to unplug your charger.
- Discover how much battery wear was endured during your charge session.
📊 BATTERY USE
AccuBattery measures the actual battery usage using information from the battery charge controller. Battery usage per app is determined by combining these measurements with information on which app is in the foreground. Android calculates battery usage using pre-baked profiles that device manufacturers provide, like how much power the CPU uses. In practice however, these numbers tend to be highly inaccurate.
- Monitor how much battery your device is using
- Know how long you can use your device when it’s active or in standby mode
- Find out how much power each app uses.
- Check how often your device gets woken up from deep sleep.
🔌 CHARGE SPEED
Use AccuBattery to find the fastest charger and USB cable for your device. Measure the charging current (in mA) to find out!
- Check how fast your device is charging when the screen is on or off.
- Know how long it takes to charge your phone and when it’s finished.
HIGHLIGHTS
- Measure real battery capacity (in mAh).
- See how much wear your battery sustains with each charge session.
- Look up the discharge speed and battery consumption per app.
- Remaining charge time - know how long it takes before your battery is charged.
- Remaining use time - know when you will run out of battery.
- Screen on or screen off estimations.
- Check the percentage of deep sleep, when the device is in standby mode.
- Ongoing notification for real time battery statistics at a glance.
🏆 PRO FEATURES
- Use Dark and AMOLED black themes to save energy.

Excellent app. My two issues are that the charge alarm is unreliable and the app doesn't auto start when the phone is restarted. Otherwise the app operates as intended once the battery management permissions are sorted out. Optimise background apps must be turned off for this app or it will be put to sleep. Even then the charge alarm doesn't seem to be 100% reliable. Everything else seems to work as intended.

Very useful & informative app! This does not "fix" anything, but rather provide the necessary info into items such as which apps are hogging up the battery & by how much. Or, how much screen time you have left w/ the current 🔋 level. Lots of other info like charging speeds, 🔋 cell health, & wear/tear. Definitely worth upgrading to Pro version!

I use this app every day, is really a great app. I can monitor my charge sessions, by observing the charge rate in miliamps (1ma =1/1000 Amp). As soon as a charger cord starts to fade in it's charge rate, I can spot this and replace the cord. Without this app, I wouldn't detect a problem right away, and it would continue to get worse and waste a lot of my time. I can check all my charger blocks with all my cords in just a couple of minutes, to see which combination of charger and cord are best.

This app has, in as few words as possible, done wonders for me. It is everything I want, need, and desire in a convenience app. It's battery tracking is possibly one of the best on the market, and it's alarm customizablity is the best I've ever had in a phone app. The only thing I dislike about this app is how often the percentage at the top left stops working, but given that my phone is actual trash, I believe that it is not the app causing the issue. Still, that is why I didn't give it 5 stars

I thought my phone was dying because either the walkie talkie app i had downloaded was wonky or that my battery had passed its useful life. Wrong on both counts. Accubattery revealed my charger was malfunctioning (actually draining the power) instead. My battery, at a year old, is at 77%, which isn't great, but this gives me time to order a new battery, and hints to make the next one last longer. Kudos Accubattery!

Neat app, provides lots of useful information, probably more than you need. Well worth a donation to the developer for the insight provided. Only drawback was I did have to uninstall when not in use, as on my Pixel it caused the battery to drain heavily. It didn't see it or seem to effect the data, but I could watch percentages drop 2-3x regular pace through the day without no other changes to routine. Phone on in mostly standby with no background app usage, screen on less than one hour, 8 hours of run time dropped battery level from a normal 100 down to 75/80% without the app running to 100 down to 44-32% with the app running.

From 5 to 1 star. This app side loads bloatware games and apps WITHOUT explicitly asking permission. Several years ago I thought it was great: simple, helpful, an occasional ad. But I recently installed it on a different phone and that same day I got over a dozen apps installed unexpectedly. I would delete three or four, and an hour or two later several more had been installed, ... repeat scenario... After I installing this app then that unexpected behavior. NOT coincidence. Very disappointed.

Great app to learn about and to be able to see the condition of your battery. Also a very useful tool to check your charging boxes and cables... Cables malfunction and stop working to their full potential often and people don't realize that the reason things are charging slow is because of broken cables, use this app to check your equipment.

The app crashes on average three times a week, and I only usually find out after I pick up my phone to find it already at 99% charge instead of getting an alert at 90%. The full screen ads are obnoxious but I suppose necessary to keep it free. It would be easier to stomach the ads if the app had seen any recent updates or stability improvements.

I like the idea, and the app is very well put together. However this app has never been updated in the entire time I've had it. But honestly what bothers the most is the endlessly long amounts of data and information they mine from the phone. There is absolutely no reason an app needs to connect that much. In the end its poorly built. The upgrade was a world of difference in quality and worth the investment. Unfortunately, they need to fix it again. Charge alarm is broken ect...android 14

It works MOST OF THE TIME. Most of the time, the alarm goes off when it reaches the desired percentage (80% for me). However, sometimes it doesn't tell me at all and this has happened often enough that it's become a problem. When i plug it back in after the alarm didn't go off and it's above the desired percentage, then the alarm DOES go off. I like this app a lot, but this one thing seriously frustrates me.

Why can't you vibrate a notification when my phone gets below a set % like say 10%. It often silently dies because I have no idea it was low. Yet you notify if charge reached. Says last full charge was 71 days ago which is false and basically impossible. My phone has completely died at least once a week. May be because the app keeps getting killed but it is not in any list that does that. Also the last 15% of my battery literally lasts a minute or two which this app doesn't accurately show.

It's been great for measuring the output of different chargers, particularly the different wall plugs + cord combinations, even which way the cord goes in, right side up vs right side down. On a C to C you can have four different combinations just in the way the cord is facing when inserted. All of this effects the amount of power your phone receives to charge it.... I wish it was more helpful than to say "don't kill my app" is conflicting with the app and limiting my capacity to receive a chrge

Regarding battery capacity chart over time. Can we please be able to say double tap on chart and do that spread two fingers blowup trick to facilitate easily finding out the last charge results. Over few months of charging, I see a graph with 100+ x-marks so close together, it takes me 10 minutes or more to isolate my last charge results. Now if we could pinch and zoom chart, that would allow user to locate last charge x-marks results instantly versus 10 minutes or more like poor old me.

Flat out DOES NOT WORK! Uninstalling this junk. Several times in past month, I've charged from 12 - 100, app says last full charge 39/48/51 days ago!! BS! Waste of space. -1 * for obnoxious full screen noisy ad on launch & VPN telling me it's blocking hundreds of tracking attempts. Also, app has been inexplicably crashing or, at least, evaporating from the notification area. This on Android 12; Continues to work fine on Android 7. I've never seen a crash on the older phone.

Now there is an easy way to dismiss the full page ads. The damned ad is full page and I see no way to dismiss it so your reply doesn't cut it. I don't mind small ads and which I sometimes click on. Now has obnoxious full screen ads so I'm dropping AccuBattery from 5 to 2 stars. Works fine. Signals 80% charge and at intervals there after. My phone doesn't support full charge detection. Has ads but they are not obnoxious and sometimes are useful. I recommend AccuBattery for Android phones.

GARBAGE. Charge number jumps all over the place. App says to turn off screen for a few minutes then come back and check 'screen off' number. But it still doesn't show anything there. Have all permissions granted to app, app just doesn't work right. P.S. Now doesn't even show charging speed at all. Can't trust this garbage app, uninstalling.

The features are comprehensive and excellently presented. But it keeps crashing randomly, every several days, and ONLY while charging, leaving my phone to silently push all the way to 100%. Since the charge alarm is the main reason to have the app, this sucks. Would be an easy 5 stars if it didn't persistently fail at the wrong time.

After 5 minutes, I upgraded to Pro. Nice slider for choosing the desired charge level. I chose 75%. When charge hits 75%, there's an audio twinkle alert. The twinkle is different than the phone's other notification twinkles. I'd expect Android 14 to have automatic adjustable battery charge limit, without me having to pull out the charge cable. I wouldn't mind if there were a beep when the battery falls below 20%. But Accubattery is simple & works well.

This app used to be a lot more useful, but now it's degraded significantly. Suspect it's been bought out or something? No longer reliably tracks my charge/discharge sessions, takes several seconds to open sometimes. Intrusive ads. Clearing data as suggested did not help. Uninstalled since I'm good about manually unplugging at 80% charge now to avoid unnecessary battery stress. Only thing it's still useful for me is seeing charging current and temperature.
