Android Phone Battery Calibration Guide – How To Calibrate & Fix Battery Issues



Samsung Galaxy Note 4 Battery

Everyone has problems with Battery on their Smartphones; that makes them re-think about their choice of phone they have purchased. It’s a known fact that the iPhone users are called the Wall Huggers, but that said Android is not also the best. We have seen that most may be 99% of the Android devices in the market have issues with their batteries & users have to keep charging them or carry a power bank with them all the time. There are also situations where the users would find some strange experiences in which the batteries do not charge or suddenly get drained or even switch off the devices because of low battery charge, but that’s not the actual case, which is when they need a Battery Calibration.

Before we start the process of Phone Battery Calibration, you need to take a look at a few parameters that can be accounted for the issues mentioned above. Let us get into them one by one.

Check Battery: It is important to check the battery’s health that, in this case, is the Physical battery & not in the software. You need to open up your Phone’s back panel and check out the battery if removable pull it out and check if there are any bulges or any openings around the battery’s sides. If the phone has a non-removable battery option, you can still try to take a close look at it by opening the back panel and noticing any strange bulges or bloats. If there’s is nothing found you and your battery is safe & you can proceed to the next step of checking the software issues.

Check Firmware: At times there are software issues where the reading go kaput, and you will find some random issues and readings on your phone. These are the things OEM’s or the brands try to fix through OTA (Over-The-Air) software updates pushed to the users. Even not updating your device firmware can make them keep running in the older versions & you can experience more drains on your phone & would blame the battery for the same. If its updated & you have ensured it’s all good, you need to move to the next step.

Check Ports: 99.99% of the Android devices right now are equipped with the Micro-USB ports that most users do not use with the Stock chargers. Call it laziness or convenience, the users prefer to keep using any random or old charger they have with them, following which because of different power outputs and cables used, the batteries turn bad & ultimately discharge quickly or store less charge than expected. The next thing would be checking the ports on the phone since the device is charged every single day; we are talking about hundreds of times the user uses the ports & since it is not a USB Type-C port, many a times they are damaged because of wrongly pushing it in. If you find any issues with these ports, probably the device won’t get charged perfectly or with loose ends the charging cycles would get counted but there are issues with the charging leading to damages in the battery.

What is Calibration: The Android OS comes with Battery Stats feature that keeps monitoring of all the activities and also the capacity if its empty or full. Sometimes this gets corrupted and the device would start showing you some wrong data under the statistics causing the phone to switch abruptly off before the battery has reached 0 perfect. The calibration process would standardise this system and ensure that the information that’s shown on the Battery Stats is accurate and you are shown the correct data. Do make a note that this is just a trial and error thing to try to calibrate the battery because we are trying to normalise the data & not doing any physical changes to the same.

Many users have also tried out different ways to perform this action, one of those being deleting the battery stats.bin file from the data > system directory but that does not help as the file is recording the data across reboots with the operations on the device. In Simple words, the calibration process would reset your battery stats through a process mentioned below & show you the correct data.

How To Calibrate your Battery: There are many different ways of calibrating your device’s battery but in this article we will be talking about the way where you do not need to root your device. In case you have rooted your phone, you can head over to our another guide on how simply you can get this job done. Followed are few of the steps for this process.

  1. Completely Discharge your Phone till it switches OFF Automatically.
  2. Turn it ON, following which it would Turn OFF again.
  3. Charge the device to 100% without Turning it ON.
  4. Its time to Unplug your Phone’s Charger.
  5. Switch your Phone ON & if its 100% then you are down or else Plug it back to the power & repeat the cycle.

Note: Its recommended not over-do this process or even do this process regularly.
