How To Calibrate Android Device Battery Stats Root No Root
What this procedure achieves is to rest the battery stats file so your battery should now be calibrated.
Battery problems are among the biggest concerns for smartphone users, which is why we offer so many useful tips for solving battery drain issues. If you notice that your battery performance and duration has decreased, it could be time to calibrate your battery. Today well explain what battery calibration is, how to tell if you need to do it and how to do it, with or without root access.
The Android operating system has a feature called Battery Stats, which keeps track of battery capacity, when it is full or empty. The problem is that it sometimes becomes corrupted and starts displaying data that isn’t real, which, for example, causes the phone to turn off before it reaches 0 percent. Calibrating your Android battery simply means getting the Android OS to correct this information so it is reflective of your actual battery levels once again.
Just follow the steps below:
9. Immediately launch the app and recalibrate your battery.
10. Once youve calibrated your battery, discharge it all the way down to 0 percent and let your phone turn off again.
11. Fully charge the battery one more time without interruption while its switched off, and the Android systems battery percentage will be reset.
Conclusion:
Put plainly: fully discharging a battery is bad for it. Trying to overload a battery is also bad for it. The good news is that charging batteries automatically shut off when their safe limit is reached and theres always a little in reserve even if your phone wont start. But again: do this only when really necessary, because it does have a negative impact on battery life.

How to calibrate an Android device battery without root access
The old fully charge and discharge approach stands as one of the simplest ways to recalibrate your Android battery. Weve warned you in the past about low voltage problems in lithium batteries and the negative impacts of fully draining a battery on its lifespan and the same holds true here. But if your phone battery is causing you real problems, its worth taking the risk.Just follow the steps below:
- Let your phone discharge until it goes off due to low battery.
- Charger your battery until it reach 100%. Do not turn on your device while charging!.
- Unplug your charger and turn your phone on.
- Leave it lying for 30 minutes then charge it again for an hour. Dont use your device while it is plugged in.
- Unplug your device and use normally until the battery is completely drained again.
- Then charge it to 100% again.
How to calibrate Android device battery with root access
Even though Im not convinced that clearing the batterystats.bin file has any meaningful effect on how the Android system reports remaining battery charge, there are those who swear by this method.
So in the interests of fairness, weve included the process for you here (it is true that different manufacturers use the batterystats.bin file for different things). Its basically the same process as above but with the added step of a root-enabled app.
1. Discharge your phone fully until it turns itself off.
2. Turn it on and let it turn off again.
3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4. Unplug your charger.
5. Turn your phone on. Its likely that the battery indicator wont say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on the screen as well.
6. Unplug your phone and restart it. If it doesnt say 100 percent, plug the charger back in until it says 100 percent on screen.
7. You want to repeat this cycle until it says 100 percent (or as close as you think its going to get) when you start it up without being plugged in.
8. Now, install the Battery Calibration app and, before you launch it, make sure your battery is at 100 percent again, then restart.

Remember that it is not recommended to perform this process all the time. Even when your battery is so dead your phone wont even turn on, your battery still has enough reserve charge to avoid system damage. But you dont want to poke the tiger with a stick. Perform this process once every three months at the most. If it is required more often than that you have bigger problems at hand.
Smartphone battery myths
Lithium-ion batteries dont have a memory so theres not much you need to do to keep them running as they should. The problem lies with how the Android system reads and displays the current capacity of the battery, not the battery itself.
The same goes for the myth that deleting the batterystats.bin file will magically recalibrate your battery. That file (on most devices anyway) simply stores data about what is using the battery when it is not being charged. It is also reset every time a battery is charged to over 80 percent and then disconnected.
The batterystats.bin file contains the info you see made prettier in the Battery section of your phone: its the Android system keeping track of your batterys usage, per charge cycle. When we talk about battery calibration, its the percentage meter that gets out of whack, and that is what we need to fix.

How to Fix Bad iOS 9 Battery Life
A phone with very bad battery life can be frustrating to the user because he/she wont be able to enjoy it fro long before it drains. Apple’s iOS 9 update continues to cause battery life problems for many iPhone, iPad and iPod touch users. With those problems in mind, we show you how to fix bad iOS 9 battery life on iOS 9.0, iOS 9.1, iOS 9.2, and iOS 9.2.1.
The iOS 9 update is here and it delivers some big time improvements to all devices capable of running iOS 8.
That list includes devices like the iPhone 6 and iPhone 5s but also the iPhone 4s, the iPad 2, and the original iPad mini.
Apple’s iOS 9 update brings a ton of new features and fixes to the table but according to early adopters, it also brings some problems. Battery life issues also appear to be affecting those that have downloaded Apple’s iOS 9.2 update and its new iOS 9.2.1 update. This isn’t surprising.
Abnormal battery drain is a common iOS problem and it always seems to show up, en masse, right after an iOS release.
iOS updates aren’t supposed to have a negative effect on overall battery life on the iPhone, iPad and iPod touch. And with Apple touting an iOS 9 battery life boost, I am not surprised to see people expressing their frustration.
How to Fix Bad iOS 9 Battery Life
I want to help you solve your bad iOS 9 battery life issues.
This guide delivers help to get better battery life on all versions of the iPhone, iPad and iPod touch capable of running iOS 9, iOS 9.0.1, iOS 9.0.2, iOS 9.1, iOS 9.2, and the iOS 9.2.1 update.
You should keep some of these tips and fixes stored in your memory bank. Battery life problems can strike your device at any time so you’ll always want to be prepared.
Look Into Your Apps
If you’re noticing strange battery drain on your iPhone, iPad or iPod touch, the first thing you’ll want to do is take a long hard look at your applications. While you might want to blame Apple for your problems, there’s a good chance that it’s a third-party application hogging your resources.
To start digging into your app performance, you’ll want to go into Settings > Battery and get familiar with the Battery Usage tool and the changes that Apple’s made in iOS 9. The tool will show you which apps are eating up the most battery but it will now show you when they’re eating up the most battery.
The tool will show you what apps have been using the most power over a 24 hour span and it also shows you what’s been eating your phone or tablets battery life over a longer span of time. If you tap on the little clock there, you’ll also be able to pull up a breakdown that shows you exactly when they’re eating up the most battery.
Some apps will drain battery the most when the screen is on and some might zap your power when the screen is off.
If you see something odd, you’ll want to first try updating the application (assuming it has good reviews). Developers have been rolling out iOS 9 support updates in recent days and there’s a good chance your apps have updates.
If that doesn’t help, try reinstalling it or uninstalling it completely to see if your overall iPhone or iPad battery life improves some.
Start Using Low Power Mode
iOS 9 comes with a brand new feature that will help you conserve iPhone battery life when you need it most.
The new Low Power Mode in iOS 9 allows users to stretch out the last 10-20% of battery life significantly longer without flipping a bunch of switches manually.
Simply go to Settings > Battery > Low Power Mode > On and the iPhone will limit many items you used to need to control manually. This can add several hours of actual use to your iPhone.
Turn On Airplane Mode
If you’re noticing battery drain, it might be because you’re in an area with spotty cellular service. If you are, your device will work extra hard to try and find a signal and that could cause your battery life to start draining rapidly.
To combat this, flip your device into Low Power Mode or Airplane Mode. Airplane Mode can be found at the top of Settings and it will kill all of your connections. If you’ve flown any time in the past five years, you’ve probably used it.
With Airplane Mode turned on, your phone won’t be searching for a better signal or any nearby connections. Just make sure to flip it off when you’re back in an area with better service.
Disable iCloud Keychain
This is a potential fix that’s been passed down over the years and there’s a chance it might work for you after installing iOS 9.
Try disabling iCloud Keychain if you don’t use it. iPhone and iPad users have reported a bump to battery life after turning it off and there’s a chance you could see some improvements.
To disable iCloud Keychain on your device, you’ll need to go into Settings > iCloud > Keychain > Toggle iCloud Keychain off. You can always flip the feature back on if you determine that there’s no connection between it and the battery drain on your device.
Limit Background App Refresh
If you don’t need your apps to automatically refresh in the background, you might want to try disabling the Background App Refresh feature that comes standard with iOS.
Background app refresh is handy is you want your applications to show the latest data whenever you open them but in our experience its proven to be a resource hog. If you have it on, apps will work in the background and that can be a catalyst for bad battery life.
Go to Settings > General > Background App Refresh > Turn it off for each app that is using too much power. It’s a tedious process but it could help.
You can also turn the feature off completely if you don’t want to go through your list of applications one by one.
Manage Your Display
Get a handle on your display.
Apple’s iPhone, iPad and iPod touch use an array of sensors and one of those sensors adjusts the screen automatically in certain lighting environments. Sometimes the sensor works to perfection. Sometimes it doesn’t.
If you’re noticing strange iOS 9 battery drain, try shutting auto brightness off. To make this happen, go into Settings > Display & Brightness > Auto-Brightness > Off. Once it’s shut off, you’ll have to adjust the screen brightness manually.
iOS 9’s Control Center offers quick access to an auto brightness toggle. To pull it up, swipe up from the bottom of your screen.
Restart Your iPhone or iPad
You should also try restarting your iPhone, iPad or iPod touch.
If you don’t know how to do this, hold down the power button for a few seconds and swipe to shut the device down. Hold down the power button again to boot the device back up.
If that doesn’t help, you can also try a hard reset. To do that, hold down the home button and the power button for about 10 seconds. The device will restart it self. As a reminder, this will not remove any of your data.
Reset All Settings
The above fixes include changes to your habits and some smaller tweaks. The fixes listed below are more drastic measures.
The first step to take is a reset on all of your device’s settings. To do this, go to Settings > General > Reset > Reset All Settings and then enter your passcode when the prompt appears.
The reset process could take five minutes or so and once it’s done, it will restore your settings to their factory defaults. Make sure you have Wi-Fi passwords handy because your phone or tablet will forget them. And as a reminder, this will not delete any of your files.
Downgrade to iOS 9.0.1
For a limited time, you can drop back down to iOS 9.0.2. To do that, take a look at our guide to downgrading.
This loophole won’t stay open forever so you’ll want to make your move sooner rather than later. Apple typically signs off on older updates for one to two weeks before pulling the cord.
Restore the iOS 9 Update
If none of this works, you can try a restore on your iPhone or iPad. This should only be used as a last resort because it erases everything on your device and could take awhile to complete depending on how many files you have on your device.
You can try restoring from your backup after the iOS 9 update. If your iOS 9 battery life issues return after the restore, you will want to try this method again without restoring from the backup. Here’s how to do this on an iPhone, iPad or iPod touch:
- Plug in and backup to the computer or to iCloud.
- Turn off Find My iPhone – Settings -> iCloud -> Find my iPhone -> Off.
- In iTunes Click Restore.
- Follow the prompts and the iPhone will reinstall iOS 9 from scratch.
- When it completes click Restore from Backup to put your information back on the iPhone or Choose to set up as a new iPhone.
This could take anywhere from 20 minutes to an hour to complete so make sure you set aside some time to do it in a quiet place without any distractions.
Take Your Device In
If nothing here works, it’s time to take your iPhone or iPad into an Apple Store to have a Genius run some diagnostics.
You could have a bloated battery, you could have something else. If your device is still under warranty, they might even offer you a replacement.
I Hope this works fine for you... Sharing is caring, do share these tips with your friends.
