Easy Battery Calibration

Follow all the instructions and it works. New logic board and battery still switching off at 56%. Fixed and now showing 72% charge remaining after two days. Occasionally one finds a well conceived and designed app. This is one. Thank you. Also, check with Power Manager which apps you really need to auto boot up when phone switched On , that will also save Battery power.

Really good. My phone dies from 15% to 45%, it can get really anoying, I calibrated it and tested it, and and it didn't turn off until it got to 0 percent! Totally recommend it, it's quick and easy you just have to have your phone at 75% of battery and have it plugged in, then you press calibrate, after that you just restart your phone!

I cant see difference before after calibration. My battery phone work as usual. But this kind of apps is really great idea.... Maybe you can add simple text/graph animation, showing progress behind this app do between 95%-100%

I love this app, it worked perfectly for me... My phone used to go off immediatly from 20%, but now it goes off when it reaches 0%. It is highly recommended.

i was exceptical but wow it really works, replaced my battery like 4 months ago and it always drained weird and always jumped from 40% to 15% in a snap and then 15% to 0% in few hours but now it works as intended

Tnxx for helping me after i flashed my custom rom my phone get switch off when the charger is not connected But atlast i found this app and after i calibrate my phone by this app my problem get solved Now i can use my phone without charging Thanks a lot

Try non-root and non-app method, no luck. Try root method with this app, boom, no more 97% stuck, charging went straight away to 100%. I had zero expectation as I was thingking this a bit fishy, I'm completely wrong. Thanks, dev. Good job.

Showed battery life at 100% as it always has. Shows days left on battery @ 3 days 18 hours. Normal days is 7 days 17 hours. After charging the phone as it instructed and tapping the calibrate button it immediately said the phone was calibrated. There was no difference.

I must say, amazing app. My Nokia 3 battery is 50/50. After calibration it charges faster and even lasts longer. Just wonderful

One of the most useful an easy battery calibrate for this app before my battery cell collapsed not work well to the charging speed and to slow all the times i had been fix it of my battery damages and assistant me my battery calibrated after then check it myself my battery always work well this great app thank u

Idk that even this works but it sloved my charging issue somewhat. The charge speed was 1% per 11mis but now it's like 4min. If ur mobiles battery is removeable plzz don't remove it. It can result in such calibration problems same happened with me.

Wasn't hard to use... but it didn't calibrate my battery, either. And my phone is rooted (and gave the app full permissions) so it wasn't an access issue.

App stuck on ad. Downloaded app, opened and immediately an ad pops up with no way to close. Had to force close app so giving 3 stars for effort

This app does nothing, don't let this app fool you, it shows an ad before so-called "callibration" then an ad afterwards but does no form of detection or processing to calibrate your battery, it's a scam!

Actually suprising it works, my phone's screen always was glitching when i lowered brightness but now it does not shake with crazy white lines when my phone has low brightness and phone lives longer since i calibrated

My battery stuck at 2% but it is fully charged. This ap won't work when it detected battery low. F#@ing useless.

Very useful & easy to use, this app can help you if you have some problem with your battery 👌🏻 *but the ads is so annoying

It doesn't work for me at all. Directions are easy to follow, but my battery data is still not reading correctly.

One of the steps doesn't make sense, the "Charge your device to at least 75%", but my battery is 87% but it says that its currently 0%

i don't mind to see the ads but please give after battery calibration results. otherwise i will rated 4 stars

It worked on my oneplus 7t. When battery reaches at 20, it is literally drain so fast. This app fixes it.

Didn't work for me because my battery percentage is stuck at 56%. So I couldn't get past the 1st stage of charge phone past 75%

It's showing that connect to a charger and charge to 75% but my phone is stuck at 31%, how can I know it's 75%

My battery is 100% charged and app is saying charge your battery to 75% currently its 0%

Best app for battery calibration. Problem solved.

Forces you to charge battery capacity till 80% only to do zero. It doesn't do anything, really 🤔
