Description

🏆 Designed to keep your battery in the best shape you can – AndroidHeadlines

AccuBattery protects battery health, displays battery usage information, and measures battery capacity (mAh) based on science.

❤ BATTERY HEALTH

Batteries have a limited lifespan. Every time you charge your device, it wears out the battery, lowering its total capacity. Scientific research shows that battery lifespan can be extended up to 200%, when you charge your device to only 80%.

- Use our charge alarm to prolong your battery lifespan.
- 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).
- Use the charge alarm to prolong battery lifespan.
- 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

- Real-time CPU and power usage overlay for spotting battery draining processes.
- Use Dark and AMOLED black themes to save energy.
- Access to historical sessions older than 1 day.
- Detailed battery statistics in notification.
- No ads

We're a small, independent app developer with a focus on quality and passion for battery statistics. AccuBattery doesn’t require access to privacy-sensitive information and doesn't make false claims. If you like the way we work, support us by upgrading to the Pro version.

Needs an option to turn off the monitoring. I dont want to use but dont want to unninstall. When using Amoled mode, the UI should change from green to black. 1 day of usage and the data it shows is far far away from accurate. Im seriously thinking in a refund, 4 days and this is far from useful, the app battery consumption does not seem legit. I like digibites, Digical, a very good product, but this... I am going to make a manual benchmark and then I update this review. Also 70 mb of ram always... Even on my OP3T

Such a well made app. The design, institution hints, everything in perfectly logical order of introducing the user not only to the new app, but most importantly to the whole concept of proper battery care. It's truly rare to see something like that. Got a pro version within minutes (something I never do so fast). Sorry I could only could afford the first donation option.. it deserves more.

Michele F. Marrini

Not worth it Does not do anything that other free apps don't already do. I bought the pro version and highly regret it, the added functions are minimal. It doesn't even show process names and the app list is rough. The interface is nice and modern but if you are looking for something detailed, this is not for you. Good to track charging times and battery cycles (it's not the only app) but avoid if you want to track battery draining processes. Pro version not worth the money.

Ronnel Caluag

What a wealth of information this app provides! I'm not sure about the usability of the charge alarm, though. It is a known fact in the lithium battery industry that charging only up to 80-90% capacity will extend the battery life. However, that refers to the "actual" capacity of the cell. Since this is known to the industry, most of the good device manufacturers have already factored it into the device power management circuitry. In other words, when you charge your phone to "full", it actually charges it to only about 90% and when the warning tells you that you have only 1% left in your battery, it actually has 5% or 10% for that matter in your battery. I am quite certain this isn't considered by this app.

hi. indeed a good app. does what it says. however, I have a few suggestions. 1) please have the option to use alarm volume so that the phone will still ring even in vibration mode 2) please have the option to remove the battery icon notification from the status bar and notification centre. ( some phone like S7 has the option to put the app under unmonitored apps so that the background process won't be killed. )

Great app, detailed, only missing a battery usage/charging graph, similar to the stock android but zoomable, with more details. It'd be more visual than just looking at the data. Other than that, it's very user friendly. For some reason it doesn't start automatically when reboot/start up the phone (Oneplus 5), probably just a switch somewhere I couldn't find.

what kind of data are you getting? Please also try the manual benchmark: https://accubattery.zendesk.com/hc/en-us/articles/213575425-How-to-benchmark-your-battery-health

Hi, the main features are the battery health and alarm, the battery usage isn't the main focus of the app. If you want a refund though you can always send us an email and mention the Google account email you paid with.

Digibites February 17, 2017

Hi, thanks for the feedback. By the way, to hide the battery icon you can go to AccuBattery - menu - settings - priority - set this to minimum.

June 25, 2017

Digibites June 26, 2017

Hi, if it doesn't automatically start you will probably need to look at task killers and other types of cleaning apps or functions that might be causing this, then add AccuBattery to the exception list.

Graham Davidson December 23, 2016

Just bought the pro version, and am excited to utilize all of the features AccuBattery offers. What a wealth of information! I may update after using it for a few days and letting the app collect more info on my phone and my usage. Is there a way to remove the notifications from the lock screen? I've tried the "show on secure lockscreen" toggle but to no avail.

Gramoz Brace February 9, 2017

I've used many battery monitors over the years and I can fully say this is the best, no doubt. I've had a small issue after I upgraded to nougat. I get negative ma values when charging. A fix for this should be easy, but it doesn't impact performance. Maybe you could allow an option to chose ma monitoring method as other apps do. Thank you for this great app! Edit: Thank you, that fixed it!

Digibites October 21, 2016

Hi, after updating your Android version please run the tutorial again to re-calibrate. Sometimes the new Android version will use different multipliers or positive/negative signs which will lead to these kinds of issues.

James M. Woodward January 1, 2017

Excellent core features, light on flexibility This application does everything it says it does and just a little more. If you are looking for something to tell you exactly how your battery has degraded over time its health based on math & science this is for you. If you want in-depth application train information or infinite settings to control functionality (even with the Pro features), you are likely to find yourself wanting.

Jonathan Brown January 22, 2017

Great app and very useful. While I am not sure how accurate the health feature is I like having it as a guide. This app has made me be more conscious of how and when I charge my phone battery, which should help extend its life. For me the only thing missing is a graph of battery history, I like this visual of how I have charged and used the phone over a time period.

Digibites January 23, 2017

Hi, if you're unsure about the battery health try a manual benchmark: https://accubattery.zendesk.com/hc/en-us/articles/213575425-How-to-manually-benchmark-your-battery-health

Jamie Cecil July 28, 2017

Very useful and informative app. But it would be nice if it could restart itself when the recent apps are cleared. Otherwise it leaves big gaps in the usage history. Also, when looking at a discharge cycle, it lists which apps have used the battery and how much, which is great. It would be nice if the app added everything up and showed you the history for a week/month, something like that. That being said, it's still a very good app.

Dante Alighieri August 28, 2017

Being somewhat of a battery geek I have found *this* app to be the best and definitely worth paying for. Updating the alarm settings is a great move. Maybe updating the temperature display with the ability to switch between celsius and fahrenheit would be useful. (Nudge nudge wink wink) Great work, Digibites. Thank you! UPDATE 8/28/17: Still using the app and finally ponied up $10.99 to donate. The reasons; I LOVE this app. The devs actually LISTEN. Did I mention that I love this app? I use it on a regular basis. Definitely worth it to donate to this (these?) folk(s). :)

Digibites August 31, 2016

Hi EvilJesus, thank you for reviewing AccuBattery. Fahrenheit is indeed on top of the to-do list :)

Benjamin March 1, 2017

It works well. I wish it had more per-app statistics rather than an at-a-glance system, correct me if I'm wrong.. Also I used GSam and liked the "past 15 minutes" usage feature which told you how quickly or slowly you would drain your battery if you continued using your device the same way. I'd like to be able to customize the notification a bit more. Pro is worth it, the AMOLED theme is beautiful. Aside from that the app is very pleasing to look at and gives you helpful information about what certain numbers mean.

David Adler October 27, 2016

So good I bought pro The stock Android battery monitor was really only showing a quarter of the story hiding most of the usage in Android OS. this makes it much clearer and provides strategies to extend battery life. Worked wonders on my battery burning galaxy S7 and helps my moto g(4) plus battery last multiple days

Alberto Cruz November 5, 2016

All the data one could need about a battery in one place Since most smartphones come with a non-replaceable battery, and I for one don't want to change phones every year (or two, or three) I have read a lot on how to care for Li-Ion batteries. This app has everything one could need for extending the lifespan of a battery, and even includes pretty helpful tips along the way for explaining what each number means. Pretty good!

Muhammad Anwar August 2, 2017

I was looking for app that can provide me details info about battery usage.. And with this app, i get more than i was expecting.. and it is just fact of information.. Although they have ads, but dev have decided to put it in a small area.. For me this is ok, but still i decided to support them and make purchased.. I hope you will success with you this attitude in business.. 5 star for you.. Edit: Before i make a purchased of this app, i saw there are widget that we can used but it is cover with Pro word.. i am guessing it is for paid version.. but once i purchased the app, i cant find the widget anymore.. care to explained?

Alan Cheung August 20, 2017

Used to be very accurate on my Nexus p6. Changed to huawei p10 plus and the numbers have gone wrong. Battery capacity is 3750mAh. After 30% usage, it told me I had used total 2800mAh. That's almost the same every single day, for more than a month.

A анонимный October 28, 2016

Bought pro - Profile switching could be cool Sent my suggestion to the official email address. I would like to have profile support, basically just having a profile for each battery. So when I use the aftermarket one, the stats and all would get recorded for that battery. (Currently you can modify the mAh but all the history and stuff will log to the same place.)

Nick Follett January 2, 2017

Alarm didn't sound... I'm sure it's great - it seems great - but I didn't hear the alarm go off and there is no option to select the alarm sound! I'm hoping this issue will rectify itself... also it only seems to recognise just under 3000mAh of a new "10,000mAh" (~9600mAh) battery. This battery lasted close to 3½ days on its first charge so it is definitely at better than 30% health!

Digibites January 2, 2017

Hi, there will be more alarm options in the future, regarding the battery health, can you send us a screenshot of where you see this? By the way you can also manually benchmark your battery health via these steps: https://accubattery.zendesk.com/hc/en-us/articles/213575425-How-to-manually-benchmark-your-battery-health

Stephen Lyon August 24, 2017

I'm not sure if this is how it's supposed to work but my charging history is always broken up into small session during a single charge. So tonight for example, I plugged in at 2%, it created a session from 2% to 10%, then 10% to 12%, then 12% to 59% and so on. Apart from this all the other data is quite nice to have and way more informative than stock android battery data.

Digibites August 25, 2017

Hi, this usually means that there's a task killer or other cleaning app closing us down. (The gaps occur when AccuBattery is not running). Make sure you add us to the whitelist. Some devices also have built in task killers so also check the system settings.

Daniel R Patton December 19, 2016

Great Awesome references for my battery usage, I always keep my phone on the charger when it's available, and now I'm learning to restrain that! Earns me points with the ladies! Last star is open for improvements, like reccomendations for how to set charging limits. Right now I'm like 85%meh ok why not whatever %.

Osmancan Sarıyurt November 14, 2016

Very nice but... App is amazing about providing information with neat visuals. But the inability to remove the notification in drawer completely is killing me. I thought it would have been included in the pro version so I bought it but still no option to turn it off completely. Add this please, I don't want to bloat the notification drawer and want to check my battery manually.

Digibites November 16, 2016

The constant notification needs to be on in order to ensure AccuBattery continues running in the background. If you don't use the charge alarm though you can hide the notifications via phone settings - apps - AccuBattery - uncheck 'show notifications'.

Azri Azhari November 24, 2016

Juicy Tried so many battery monitoring apps and completely stop using any for a while. Till I found this app. It does it's job well and rather accurate. I have a question. When it's calibrating in the tutorial, do I need to keep the screen turned on or can I have it off? I'm getting two different calibration values from both variables.

Digibites November 27, 2016

Hi, do you mean you turn the screen off manually after starting calibration, or that the screen times out after x seconds, and when this occurs your calibration value is different? Can you also send me a few screenshots of which value you are referring to? Thanks in advance.

Ant Gaskin November 29, 2016

Great. This app, unlike others, shows no discernible battery drain whilst providing all the info you need to target battery drain issues. Helped me solve a couple of issues. Only used the free version but pro has even more tools. No root required either! All good.

Paul Avallone June 2, 2017

Really fine app. So much pertinent information on battery performance, health & usage. Runs flawlessly on my LG G6 with the new Nougat operating system! No more multiple battery dilemma for me like with my old LG G5. I have the paid version of this app. which is definitely worth it! Many great options! Thanks for all your help in answering my questions about the app. The developers are just great about tech support & question from the app. user's. I couldn't be more satisfied! Thanks for such a great app.!

Digibites September 14, 2016

Hi Paul, thanks for the awesome review and also for supporting us. More options for users with multiple batteries is something on our request list and something we're considering.

Tony Walton April 24, 2017

Not completely convinced. I've been charging this phone to 100% since I got it over a year ago. Yet this app reports "105% health". It got the battery capacity right per the label on the battery - guess I'll run a recharge cycle a few more times before judging.

Adrian Mancini November 20, 2016

Best battery app I have found. This app is really great. It is accurate, unlike others that I have tried. It does exactly what I need, I am very pleased. One thing though, could you guys offer a lower donation price? £3.50 works out to $5 here. Kinda pricey for an app. Edit: bought it today!

Digibites September 26, 2016

Hi, thanks for the feedback, we'll take this into account.

Ryan Lake November 29, 2016

Best battery monitor app After trying a few battery apps this one is the best by far. Good interface and useful statistics. Only thing I don't use is the charge alarm, unfortunately I am one of those people that prefers the extra runtime to longer battery life. But with AccuBattery at least I can see how much damage I am doing.

October 19, 2016

Almost perfect on S7 Great app. The screen off data is the most important feature I want. But after charge cycle screen off info sometimes doesn't show, even after reboot.Have to constantly reboot to get deep sleep to show values after charge cycle. Other than that small inconvenience it's a great app for monitoring current draw.

Digibites October 17, 2016

Hi, can you send me a screenshot and circle on it what's not showing? Thanks in advance.

Sentient Art April 16, 2017

Very useful app no doubt about. My only concern is the info displayed on the status bar. I understand there's an option to minimize this feature, but I would like for it to be completely gone from my status bar. The only way I can get rid of this notification display is by blocking all notifications from the app in system settings.

Daichi Bisbee May 9, 2017

This app is very, very handy. I use it on a daily basis. I can't tell what's eating my battery so I can force close it later. Not to mention, I really love the notification in the notification panel. I just love how the notification shows how much my battery is draining. Do I recommend this? HELL YES! it's been saving me more battery. Don't hesitate to get this.

Danny Sotoudeh July 22, 2017

Awesome battery monitor app. Got this because having a Galaxy S8+ with a non changeable battery, I wanted to keep it healthy as much as I could. This app will tell you EVERYTHING about your battery you would want to know EXCEPT it does not have a cycle counter. I leave one other battery app installed also JUST to keep an approximate count on my charge cycles for my battery, I hope the developer add this soon.

Dennis F May 2, 2017

It's not very I bother to write a review for apps... But this one.. I love it so much! I never knew they harm I was doing to my battery. Having a galaxy s7, the battery isn't the easiest thing to replace.. So knowing this can defiantly help me keep a good hobbit from now on. I very much enjoy this app and have even donated. I would like to maybe see a few more donator features to justify the the other levels of donation. Other than that this app is wonderful, really helps me stay on top of things

Christopher Straßer December 11, 2016

Extremely useful As a reviewer this tool is extremely useful to track battery life and charging time. The only thing I dislike is that it won't work if the power IC doesn't support current readout. It would be good to support usage tracking solely based on screen-on time as well.

Andrii Gritsevskyi March 30, 2017

Clear and nice interface. Fairly good estimates (it is pretty difficult task and accuracy depends on specific phone design/SoC used). It is not clear what are technical benefits for obtaining Pro version. I am considering it anyway to support author. It is truly solid work.

Reece Gale January 8, 2017

Brilliant Has changed the way I charge my phone. It also helped me establish the root cause of random reboots was a fault with my old battery and proved that a new battery fixed these issues. Very comprehensive and informative, check out your stats after 3 days use for best info.

Jason Dubar April 27, 2017

This app gives me so much data on my phone's battery, it's astounding. I love seeing which apps are draining my battery and what the overall life of my battery looks like. I'm not a fan of the icon in the toolbar, but I've learned to live with it. Fantastic battery app... It's even backed by science!

Joshua Jaeger February 2, 2017

Best app of its kind, hands down. All the readings and data I could have ever hoped for! I'll upgrade this review to 5 stars if it completes the task I'm trying to use it for. I'm setting the "design capacity" to match a new 6,500mAh battery I've purchased. I'm not sure if that aids calibration or increasing charge limits. So far, my V10 still thinks it's on a 3,000mAh and charges to "100%" after 1½hrs 😕

Digibites February 3, 2017

Hi, this means your internal charge controller can't take into account the third party battery. There's not much we can do about that though. You'll still get the 6500mAh out of it, the phone's battery % is just going to be off. With regards to AccuBattery, to test estimated capacity you will need to use a manual benchmark: http://bit.ly/2iA3Np2

Sapiderman Lumpat November 12, 2016

Very very useful! Plenty of statistics that help you optimize your phone. Find that runaway app that's killing the battery or find out how you are using your phone. Wishlist: get the app to control the internal phone charger, to stop charging at 80%..and leave it at trickle to maintain it. Then it would be perfect.

Digibites November 14, 2016

Hi, that's going to be quite difficult as Android doesn't normally let apps control when it should stop charging. It could work for rooted users but that will also lead to other issues. At the moment we don't plan to add such a function but it's something we're keeping in mind.

Anton K March 2, 2017

It shows various statistical data, but it looks quite redundant (useless?). The app answers typical questions in a sophisticated way. Some estimates look incorrect. And on my device (Doogee X5 Max, Android 6) it wasn't able to provide any data on the Health tab. Uninstalled...

What's New

What's new in AccuBattery 1.1.6-1.1.7:

- 1.1.7: Minor fixes and improvements

- Improved end of charge detection. Phones often report 100% before the battery is full, keep counting until no more power flows into the battery. This can take up to an hour after "100%".

- Added Fahrenheit temperature scale

- Added Chinese, German, Japanese, Korean, and Ukrainian and language switching in preferences.

- Reduce power usage caused by AdMob.
