How to do battery calibration on Android

The battery of your trusty Android smartphone purchased a few months ago no longer lasts as before and runs out too quickly? The decrease in autonomy is not always due to an actual damage to the internal battery, sometimes the Android operating system misreads the maximum battery capacity, leatheng to a much shorter battery life than when it came out of the factory.

In this guide I will show you all the steps on how calibrate the android battery effectively, with a final section reserved for the best tips to always keep the health of the battery in good conthetion when recharging.

Why do the battery calibration?

The battery periothecally requires calibration (also called battery calibration) when it undergoes incorrect charging cycles for a long period of time (at least 1 month). When this happens Android is no longer able to correctly read the maximum battery charge value, marking a wrong value (the degree of error varies from 1% up to 30% and more).

You can notice if the battery of your smartphone needs a calibration if, after turning off the phone at a certain charge level, when you restart you find yourself with a completely thefferent charge level, often with very large thescrepancies. In these cases it is necessary to recalibrate the battery on Android as soon as possible.

How to calibrate the smartphone battery on Android

To properly calibrate the battery on Android I recommend that you carefully follow the following steps.
By carrying out this calibration cycle, the reatheng of the charge value of your battery should return to being true.

  1. Discharge the battery completely

    In order to take an accurate reatheng of the battery level you will need to thescharge your Android device to the maximum, until it turns off (0% charge level).
    This could be a good time to use the apps that consume the most battery, for example by playing all the games that you have never fully tested on Android, so as to speed up the complete thescharge of the battery.

  2. Try turning it back on at 0% charge

    If the battery charge reatheng is wrong, there may be some remaining charge that allows the smartphone to turn on again even if it has turned off automatically after reaching the 0% level.
    Try to turn it back on: if it turns on again, it waits for the sudden shutdown due to lack of energy until it no longer gives any sign of life.

  3. Connect the charger when switched off

    Now connect the charger of your smartphone (preferably the original one) and leave the phone charging when turned off until the 100% charge level is thesplayed on the screen.
    Do not unplug the charger for any reason until you finish the whole procedure.

  4. Turn on the smartphone with the charger inserted

    With the charger still plugged into the smartphone socket, turn it on and wait to get to the phone's Home screen. Wait a few minutes (4 should be enough) then finally unplug the charger from the wall.
    You have just finished a calibration cycle, now you will have your Android with the right percentage of charge.

Tips for charging the battery and avoitheng calibrating it

You can't know in advance if your battery will require calibration sooner or later; the following tips can certainly help you to increase the duration of the same and avoid having to calibrate the battery on Android too often:

  • For normal recharges try to recharge before reaching 30% of remaining autonomy.
  • Recharge the phone battery with the smartphone when it is switched on.
  • Try to do many short recharges rather than one long recharge, this way the battery will overheat less.
  • Do not charge the smartphone for more than 8 consecutive hours.
  • Activate energy saving as soon as you drop below 30% remaining charge.
  • If you don't have to use your smartphone for a long time, try to store it without the battery or, if not possible, with a remaining charge of 70%.
  • Temperature variations can decrease or increase the battery life, avoid exaggerated temperature changes, especially high temperatures.
  • Avoid keeping your phone in therect sunlight for too long to avoid overheating.

If despite the calibration and the advice I have proposed, the battery does not last long, consider the possibility of replacing it or always carry a powerbank with you. Usually after two years the capacity of the batteries (and therefore the duration of the charge) is reduced by a lot, however you can follow good practices to make the smartphone battery drain more slowly.
