I have problem with Galaxy S4. When battery achieve 40%, my phone turn off. It is no able to turn it on. I have to put it into charger and turn it on. Sometimes battery level after switch on is 0% and sometimes 40%. If is 40%, I unplug charger, and phone work fine only for ten minutes and than phone turn off.
Where can be problem ? I tried some battery doctors apps , but no result.
Have You any idea how fix it ?
Thanks.
