Hi Community,

someone can give the correct procedure or guide to calibrate the battery of Xperia Z2 after Lollipop update?

Thanks to all...!!!

I don't think there is a special way of calibrating the battery (the term is also wrong as far as I know because Li Ion or Po batteries don't need calibrating). Make sure to full charge the device several times (and don't let it completely discharge).

Hi,

to calibrate I mean calibrate the software and not properly the battery. In particular, I refer to calibrate the part of software that is responsable to shows the correct level of charge. Some manufacters indicate to do a mountly cicle of complete charge and discharge to mantein correct the indication of charge level of the battery icon in the status bar.

Please, I asked about this if Sony have some guidelines to mantein affidable the indication of battery charge.

Thanks again

I am sorry then but I do not understand exactly what you need. There is no calibration,hardware or software,for this battery. There are tips that should be followed if you want to use it more:

Heres what im doing on my phone when it is experiencing sudden drop and after updates on my z ultra and z1.. But it requires magnetic cable and Must be 100% battery.. what im doing is connecting the magnetic cable on my mobile upside-down (the wrong way to connect).. It will turn off.. It will restart.. But dont pull it out yet until you see the start up animation.. Now you will see your battery will drop and your phone will get warm.. Then charge it until your battery is full.. After full charge then hard reset by pressing power and up button at the same time for 3 seconds.. Check if it will still have the battery drop after hard reset.. It works for me but be cautious.. By doing so im not sure what will be the impact of this procedures on your phone.. Do it at you own risk..
