I have an Xperia Acro S, and it's 1.5 years old . Yesterday i noticed that after playing some candy crush and clash of clans (to consume time), my battery has not gone down yet! Still 100%! and then after a few hours, it shut down. Charged it then in the logo of the battery( before booting, turned on because of plugging in a charger), it was red then the screen went off ( AFK) then right after it i pressed the lock button and the Battery's FULL , ye with the battery picture with green, but just a few seconds ago it was red. I don't know if it's just the battery percentage "counter" has a problem or the battery itself is not charging. Please help, Did a factory reset but it wasnt helpful. WHAT TO DO? THANKS IN ADVANCE!!
