Battery Calibration (v. 1.2) Разработано NéMa |
Requirements: Android 2.1+ | Root permissions
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
The app shows your actual battery status, and only allows you to start the calibration (i.e. removes the file) when it's fully charged, unless you force earlier calibration.
The voltage meter can be useful too. Full charge is around 4200mV.
There is an option to beep when 100% is reached so you don't have to closley follow the changes.

[2013-08-15] A Google User: Calibration failed I have root.And when first open this app,it say my battery bin had been removed.Maybe because i used Sd-Maid to remove battery state. |
|
[2013-08-14] A Google User: Very Good My battery percent now read more accurately. Thanks dev! |
|
[2013-08-13] A Google User: Battery charging very slow!! Calibration done.. I followed all the instructions. Okay. But now my phone is taking 8 hours to fully charge!! What have this app done to my phone?? |
|
[2013-08-12] A Google User: Great app. Of course this doesnt improve battery life but it does allow the system to display the true value of the battery charge, very useful when rom jumping. Thanks devs. |
|

|
[2013-08-05] A Google User: Awesome Since twrp doesn't have the option to wipe battery stats like cmw recovery does, this app is my best friend when changing roms. |
|
[2013-08-02] A Google User: Good app, no special permissions |
|
[2013-08-01] A Google User: Works fine Nice one |
|
[2013-08-01] A Google User: Works as advertised |
|
[2013-08-01] A Google User: Works great Does what it says which is to delete a certain system file and then it's generated again. This will not extend battery life. It will just make the system show correct battery percentage. Thanks for the application. |
|
[2013-07-29] A Google User: Good. To all you idiots out there. This app doesn't improve battery life! I just calibrates battery readings so that it shows the correct one! |
|
[2013-07-29] A Google User: Cool. |
|
[2013-07-25] A Google User: José A. "...240713...s...to work...just fine...thanks..." |
|
[2013-07-25] A Google User: Very nice application... must have after flashing your roms |
|
[2013-07-24] A Google User: Does absolutely nothing Clearing batterystats.bin has zero affect on your battery. Always has done, always will do. |
|
[2013-07-22] A Google User: jjj hhh |
|
[2013-07-22] A Google User: Cool Awesome |
|
[2013-07-22] A Google User: Gud app Very good app increases ma battery life |
|
[2013-07-20] A Google User: Good Very nice.. Now my battery last longer.. |
|
[2013-07-19] A Google User: Does what it's supposed to. This worked great for me. After flashing my phone with a new ROM. Battery seemed to be discharging way to fast. Reset did the trick. |
|
[2013-07-18] A Google User: Works great After a few weeks of my cellphone dying after a few hours it only took the calibration to make it last over 12 hours |
|
[2013-07-18] A Google User: Great app Calibrates my phone battery stats after flashing a new rom. Thanks to developers. :) |
|
[2013-07-17] A Google User: It works, I guess |
|
[2013-07-17] A Google User: Simple Never had a problem with it. |
|
[2013-07-15] A Google User: Right. Thanks for wiping the info of my battery usage. Big help there. -_- |
|
[2013-07-15] A Google User: Super Super |
|
[2013-07-14] A Google User: Works like advertised This isn't going to make you battery last longer, just read more accurately. Used this app for two years. Always stabilized my battery stats |
|
[2013-07-14] A Google User: Gets the job done Plus it's free. |
|
[2013-07-11] A Google User: Love |
|
[2013-07-10] A Google User: Not work on Nexus 4 First open this apps stuck in black screen. No respond. Please fix it. thx |
|
[2013-07-10] A Google User: Galaxy Nexus on MMuzzy I've been using this app for years, and to this day, does it's job better than any calibration tool I've used. Remember people, it doesn't extend life, it allows your battery readout to be more accurate. |
|
[2013-07-10] A Google User: Do I need to recalibrate!! Do I need to keep recalibrating my device? I guess so since I calibrated it once and now again the battery it behaving erratically :-( |
|
[2013-07-08] A Google User: Calibration failed! Make sure your device is rooted. On a rooted droid DNA. |
|
[2013-07-07] A Google User: It works fine |
|
[2013-07-07] A Google User: Best app Must have app for root and pro users like me who always love to try new roms. |
|
[2013-07-04] A Google User: Thes authors electronically ignorant The problem is if the battery is only reaching 40% your device lists it as 100% and you run one of these calibrators, you've accomplished NOTHING. And they are all the same. I ran my 8 aH battert down physsically wwith a 10 watt resiisstor, recharged it and it was at 100% 2 hours later. I calibrated and it's still saying 100% afterward when as an electronic engineer, I know it is not. A better calibrator would run the battery down to nothing THEN, reset to 0% no 100. |
|
[2013-07-04] A Google User: Oke |
|
[2013-07-04] A Google User: Kiváló program Hibátlanul működik |
|
[2013-07-03] A Google User: Root your device first!? All I get is a pop up message telling me I have to root my device first with no instruction on how to do this. I tried burying it up to its neck in compost, but that didn't work either. My advice, understand your machine before installing this, am uninstalling ... hey ho, back to the old drawing board :-/ |
|
[2013-07-03] A Google User: Great It works great but it need root to work. |
|
[2013-07-03] A Google User: Works well It does what it says |
|
[2013-06-30] A Google User: Thanks dev! It actually works unlike other apps out here!! |
|
[2013-06-30] A Google User: Hasn't failed yet! Thank you! |
|
[2013-06-30] A Google User: Does its job:) Expect no miracles, read the description;) |
|
[2013-06-29] A Google User: Waste of space If your rooted just go to RECOVERY and wipe batt stats. No need for this app. |
|
[2013-06-28] A Google User: Made my battery wayyyy worse Stupid app don't use! |
|
[2013-06-28] A Google User: My battery life is worse now :( cm7 nightlies d1 |
|
[2013-06-27] A Google User: Not a bad word to say about it! Awesome app! I had a problem with my battery in that it wouldn't charge beyond 82%. After installing this app and calibrating my battery it charged to 100% for the first time in days! My battery is like new. I was going to swap out my battery for a brand new one and even install a new usb port but after using this app just once I've no need. Awesome work Dev! Keep it up! :^D |
|
[2013-06-26] A Google User: best battery app ever it does what it says and now my battery last longer now i can get 6 hours on screen time through a day and a half |

[2013-06-15] A Google User: Good app Yeah this is the #1 apps for people like me that switches around with roms. Good battery calibration |

|
[2013-06-13] A Google User: Worked prefectly Flashed a new rom and the battery was completely miscalibrated. Ran the program and it did exactly what it was supposed to. Battery is calibrated and reads accurately |
|
[2013-06-12] A Google User: Thanks |
|
[2013-06-12] A Google User: Use it with every phone I root |
|
[2013-06-12] A Google User: Very helpful app indeed All of the comments saying stuff like "This app ruined my battery, now it won't even charge at all!" are trolls. Been using this since 2.2 and now on my newest phone at 4.2 and it's especially helpful when trying to get an accurate read after flashing over a new ROM. Give it a try, you won't be disappointed :-) |
|
[2013-06-10] A Google User: Killed battery on my Note 2 Battery dies out a lot faster now. |

|
[2013-06-04] A Google User: Fail Wont work on unrooted phones. Too bad. |
|
[2013-06-03] A Google User: Not worth rooting my phone As stated above not worth it |
|
[2013-06-01] A Google User: Ok Ok |
|
[2013-06-01] A Google User: Long time no update Used it on me droid 2 global... But useless on my xperia z |
|
[2013-06-01] A Google User: Good! Does what it says. |
|
[2013-05-31] A Google User: Don't have to go through boot loader Nice. |
|
[2013-05-30] A Google User: Awesomeeeeeeeeeeeee It helps me a lot.Thx for useful app :) |
|
[2013-05-28] A Google User: Batterry calibration is calibrationing app of batteries for rooted android devices. |
|
[2013-05-28] A Google User: Worked! My battery would go down about 10% in 10 mins after fully charging. 15 mins in and only 1% down! |
|
[2013-05-28] A Google User: סתם בושליט, לא עושה כלום חבל להתקין, אם הבטריה מזייפת במדידה שלה היא תמשיך לזייף בדיוק אותו הדבר אחרי ביצוע ההוראות של האפליקציה הזאת. |
|
[2013-05-26] A Google User: Great My phone battery meter have a slight improve. Will continue using it |
|
[2013-05-26] A Google User: Totaly worth it! Calibrating battery (wiping battery stats) using this app gave me best results. I've been wiping my battery stats through CWM but it only worked for 1 charge, after that my battery stats became unstable just like always. Finally after using this app my battery finnaly lasts more than 1 day just like before! Btw, Just make sure you have rooted phone. |
|
[2013-05-25] A Google User: Placebo effect Battery calibration is just a myth. After battery recharge battery.stats always is wiped. So no need for this kind of apps or something else. Calibration is myth and nothing else :-) |
|
[2013-05-23] A Google User: Wrecked my battery! Phone now discharges by 40% in 15minutes! |
|
[2013-05-23] A Google User: Nice!!! Its really recalibrating my battery indicator. Before using this app, my battery indicator very unstable, now after use this app, it's showing the real battery stats!! |
|
[2013-05-22] A Google User: Samsung galaxy s3 Perfecto |
|
[2013-05-19] A Google User: Boo.... In the past I used it and it works grate. Now its not loading .... |
|
[2013-05-19] A Google User: Why? Not just go into cwm and delete the battery stats yourself,you don't need no app.i suppose its good for the noobs :) |
|
[2013-05-18] A Google User: This is for root users only!!!! Im a root user,and this is recommended for people who have root their devices and flash a custom rom,i know how to root a device and how to flash a new Rom,i have flash several roms in my divice and i follow the steps for battery calibration,wait to charge 100% calibrate unplug the charger and then fully drain the batery but i really don't see the change at all.... My phone drain batery like hell :/ |
|
[2013-05-16] A Google User: Works fine (with a minor issue) I had a slight problem while making a full discharge - full charge cycle after the calibration, the system claimed the battery is fully charged after ~5 minutes of charging. Unplugging the charger caused the battery level to drop to 5% immediately. Not sure if it's normal after calibration, but connecting the charger the second time, I could charge the battery to its full capacity and now have a reliably working battery meter. The app has a very straight-forward interface, showing all the relevant information on a single screen and does it's job as expected. Thank you, developers! |
|
[2013-05-16] A Google User: Good app It simply does what it says, thank you |
|
[2013-05-15] A Google User: Love this I've been using this foot over a year it's still the most reliable I've found to date! |
|
[2013-05-14] A Google User: Simple best! Good! |
|
[2013-05-14] A Google User: Great All I was looking for |
|
[2013-05-13] A Google User: HTC one Working great....... |
|
[2013-05-12] A Google User: Good app Clearly, a lot of users need to buy a dictionary and understand what "calibrate" means. |
|
[2013-05-11] A Google User: Works great Helped with my battery life after I changed ROMs. worked well and I didn't have any issues. |
