It is common in MTK6589 chipset's battery drop from 20-25% to 13%. Nothing new, you have to live with it. But if battery health is not good or not synced fully, it may show drop
from 30% or even from 50%. You can also face this issue after
installing a new ROM.
You can Follow some tips listed below on Battery Calibration.
1. Install any battery sync application from playstore, like this.
2. Then charge the mobile to 100% and run this application and Press "Synchronize Battery" button and remove charging cable and use upto 0%.
3. Then Repeat this process once again, if you are doing this for first time. A weekly synchronization of battery and using it upto 0% will keep your battery synchronized.
1. Use your phone till it battery reaches upto 0% and it automatically shuts down after that.
2. Then charge your phone to 100% but don't use phone while charging, let it go from 0% to 100%. Repeat this 2/3 times, now your phone should be properly synchronized.
1. This method works only on rooted rom. First charge phone upto 100% or 99% (if stuck on 99%). Then open file-manager with root access and delete following file.
/data/system/batterystats.bin
2. Then power off the phone normally (dont reboot). Wait for 3/4 minutes and then switch on phone. Now your phone should show lesser count like anything between 30% to 90%. Now you will be able to charge phone normally upto 100%. Your battery will be synced this time.
