Whenever your phone is 100% charged , reboot it while the charger plugged in. After the reboot you will get the actual battery level. Suppose it is 80%. Now let it charge to 100% again.
Then reboot again. Keep rebooting your phone whenever it reaches 100%.
Do it till until just after reboot it shows 99-100%
Worked for me after wiping battery stats.
