Often when a phone’s battery is acting oddly, people assume it’s time for a new phone. But that’s not always the case. Instead, you may simply need to calibrate your battery. Here’s why you should perform an Android battery calibration, and how to do it.

Why Do I Need to Calibrate My Battery?

Batteries will inevitably see a decrease in performance over time. That’s just simple physics: As ions flow between the anode and the cathode of a battery, the cathode wears out. In fact, this happens even if you leave your phone in a drawer. And it applies to all batteries, from your car to your phone.

However, this performance decrease is rarely as dramatic as your phone may make it out to be. You may see statements that batteries will last for “only” 500 charge cycles, but like any product, performance can vary from battery to battery and even between individual batteries of the same type.

It also depends on your charging habits; if you charge your phone to 100%, and then don’t use your phone very often, letting it discharge all the way down to almost empty, you’ll experience very different battery life than a phone you use constantly with the screen on full blast.

As a result, your phone’s battery tracking tools and the battery itself are usually at least somewhat out of step with each other. This desynchronization is common as batteries lose slight amounts of performance. Yet even small amounts of desynchronization can wreak havoc; imagine if your gas tank indicated it was “full” when it was really only 75% full. You’d probably be fine most of the time, but when you push it is where you run into trouble.

Adding to the problem, as your phone struggles to make sense of what it’s being told, bad data piles up, causing errors and making it more difficult to get an accurate reading. Calibration will “clear the decks” and make this easier to do by allowing your phone to figure out what’s 0% and what’s 100%.

When Should I Calibrate My Battery?

Ideally you should calibrate your battery every two to three months, after your phone has been exposed to extreme cold or extreme heat, or if your phone is showing the following symptoms:

  • Showing a full charge, then suddenly dropping extremely low.
  • Staying “stuck” on one charge percentage for long periods of time.
  • Showing the same charge percentage after both charging and discharging.
  • Discharging more quickly than expected.
  • Refusing to charge.
  • Needing to charge your phone multiple times a day, or needing to leave it plugged in during the day.
  • Reporting battery issues via pop-up even though the phone is working fine otherwise.

Before You Calibrate Your Battery

If possible, before calibration, you should visually inspect your battery. If you see bulges or leaks, or if your phone’s casing is beginning to loosen or crack, your battery itself is damaged and will need to be replaced. This is especially true if there’s a noticeable decline in battery performance immediately after dropping your phone.

You should also clear your Android phone’s cache and, if available, run any and all available firmware and operating system updates. This will help with the calibration process and may address other issues.

Do I Need to Root My Phone to Calibrate My Battery?

You may read that rooting your device and deleting a specific file, usually called batterystats.bin, is the only way to truly calibrate your battery. This isn’t accurate.

What, precisely, this file does varies from company and company, but generally it stores the database that your phone’s battery indicator uses to inform you about your phone’s charge. Deleting this file may be slightly quicker, and it’s usually harmless.

But unless your device is already rooted, the procedure for calibrating your battery is simple enough that it’s likely an unnecessary step. And if you’re not sure how your phone uses this file, or any file, you should leave it alone.

How to Calibrate Your Android’s Battery

You may want to coordinate this process while you’re near a landline, staying at home for the day, or otherwise not in need of your phone. Also do not leave your phone uncharged for long periods of time. Doing so may force it into “deep discharge,” which wears out the battery completely and will require it to be replaced.

You can use your phone normally during the process of discharging the battery.

If your phone doesn’t charge beyond the initial percentage you see, this may be an indicator of more complicated battery issues. Take it to a certified repair shop or carrier store.

How to Calibrate Android Battery and Tablet 2023

How to Calibrate on Your Android Battery and Tablet – Battery problems are the biggest problem that Android phone users must experience. If you feel that the battery performance and duration of use have decreased, then maybe it’s time for you to do a battery calibration.

How to Calibrate on Your Android Battery and Tablet 2023

But before that, you have to know the reason why the battery performance decreases. Is it because of an Android calibration system error or maybe your battery is damaged? You must check this before doing battery calibration.

If you have an Android phone that has a removable back cover, then turn off your smartphone, open the back cover, and see the state of the battery inside.

It’s easy to find out if your battery is damaged or not.

If your battery is slightly enlarged from its normal state, chances are that the battery is damaged and calibration will never help solve your Android battery problem.

But if you feel the battery is still in good condition or your cellphone can’t be opened the back case, the battery calibration might help.

What Is Battery Calibration?

The Android operating system has a feature called Battery Stats which continuously tracks the capacity of the battery when it is full until it runs out.

But sometimes, this feature malfunctions and ends up displaying incorrect data. For example, the original battery capacity is 30%, but Battery Stats is displayed as 0%, which of course automatically causes Android to suddenly shut down.

And this battery calibration aims to improve the Battery Stats feature so that it displays the real battery state.

So we need to press it again, if your battery is damaged, for example, due to playing too many offline RPG games, this calibration process will be useless.

How to Calibrate Android Battery Without Application

The first method recommended by us is without root, or manually without an application. This method is actually quite simple, namely by charging the battery fully and using it until it runs out.

Here are the steps you must take to calibrate the Android battery without an application.

  • Charge until it is full then use your smartphone until the battery is completely used up.
  • Then charge Android without turning it on at all, and let it be completely 100% charged.
  • Unplug the charger when it is 100%.
  • Turn on Android, when it enters the home screen, most likely the battery indicator does not reach 100%, so charge Android again, which this time is on until the battery indicator on Android indicates 100%.
  • Unplug the charger when it reaches 100% and restarts Android again.
  • This time, look again at whether the battery indicator is 100% or as close as possible to 100% (98 or 99), if it is not yet close, then do the above process until the battery indicator figure after restarting is 100% or close to it.
  • When after restarting the battery is 100% or close to it, use Android until it turns itself off again.
  • Then charge your Android until it is full once again without being used at all.

And in this way, you should be able to reset the Battery Stats feature so that it can return to normal again. However, you should know that it is not recommended to do this process regularly.

At least do this method a maximum of once in three months, even if you do it more than once in the last three months.

It is worth noting that making Android completely die is bad for the battery, as well as fully charging Android but the charger is not unplugged, even though currently many cellphones have the Auto Cut feature.

Again, do this if you really need it, because after all this process can have a negative effect on your Android if you do it too often.

How To Calibrate Android Battery With Root

For this second method, it is arguably easier than the manual method without root, all you need is the Battery Calibration application which can be downloaded for free via the Play Store, and of course, your cellphone is already rooted.

If you are not sure whether the smartphone you are using is rooted or not, please download Root Checker which is also available for free on the Google Play Store.

If you are sure, then please follow the steps below.

  • First, download the Battery Calibration application first.
  • Make sure the battery from your Android is full, aka 100%.
  • Then restart, and immediately open the application shortly after the restart process is complete.
  • Click Calibrate.
  • After that, use Android until it turns itself off.
  • Chargeback to full 100% in a dead state and then your Android can be used after the charging process is complete.

How To Calibrate Battery on Android Device

Battery life is a major concern for Android smartphone users and the increased versatility of our devices have made the demand on them much more than it used to be a few years ago. After a while, you may notice a decrease in the battery performance of your device. It is normal to notice a slight drop in battery performance over time but if this deterioration happens drastically and you’re sure that the battery itself is not the problem, then re-calibrating your battery may help.

This problem usually arises due to irregular charging patterns or misbehaving apps. Flashing a custom ROM is also a known cause of drastic battery drain.

What does it mean to calibrate your battery?

The Android system has a built-in indicator that tracks the level of charge remaining on your battery and this is how it knows when it’s full or empty.

Sometimes, this data becomes corrupted and it starts showing the wrong information due to an incorrect detection of battery level. For example, your phone may shutdown suddenly when there’s still a substantial charge on your battery.

If this happens, you definitely need to calibrate your battery. What battery calibration does is to simply reset your battery stats and generate a fresh batterystats file to clean out all fake information and get the Android system to start displaying the correct data.

Before you begin with battery calibration

Check if your Battery is the problem

If you have a removable battery, take it out and check if it’s not bloated or swollen as that may indicate a damaged battery which in that case, calibrating will make no difference. You have to replace your battery if you find physical damages or at least take it to a repair shop for expert opinion.

Clear cache partition

Battery drain is a common complaint when upgrading to a new Android version or flashing a custom ROM. Before you calibrate your battery, make sure to clear your cache partition.

To do this, reboot your device into recovery mode, scroll to “Wipe Data/Factory reset” and click the “Wipe Cache Partition” option.

Once that is done, you can proceed with the rest of this tutorial.

Calibrate your battery on a non-rooted Android device

For non-rooted Android devices, calibration is a manual and could be a bit cumbersome. There is no guarantee it will work and sometimes, it could actually harm your battery further. But if you are facing serious issues with your battery, you can decide to take the risk.

Just follow the steps below:

  • Let your phone discharge until it goes off due to low battery.
  • Charge your battery until it reads 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. Don’t 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.

What this procedure achieves is to rest the batterystats file so your battery should now be calibrated.

Calibrate your battery on a rooted Android device

For rooted users, the process is much simpler. Make sure your battery is fully charged before continuing:

  • Click the calibrate button. Grant the application root access.
  • Reboot your phone and use it normally until it reaches zero percent.
  • Charge your phone again until 100%.
  • You should have a correct reading from the Android OS now.


That’s all there is to calibrating your Android battery. If this works for you, do let us know in the Комментарии и мнения владельцев section below. If none of the methods described above works for you, it is likely that your battery is damaged and may need to be replaced. Seek expert opinion and make sure to get an original replacement.
