Xperia ZL Sudden Death(maybe)

[Archangel_Sam]

Well, i am playing Clash Of Clan with my Xperia ZL today with a power amount of 48% while it suddenly black out.When i turned it on again it just show my unlock screen,once i swipe to unlock, it went dead again,sometimes i just saw the Sony or the Xperia word then the phone went dead again,there was 2 time i successfully unlocked my phone and it shows that it takes up half of the phone battery which become 28% and 11% for second and third time and my phone is hot without any application running before it went dead,i think it is a system bug but when i connect to PC Companion, it just shows that no device is connected, what is the issue and how can i fix it? i can only turn it on when it is plugged to the PC or Wall Charger,please reply and help, all help will be appreciated, thanks!!!! 

p/s: before this i had faced a battery problem that consumed up all battery in one day and cannot be charger

Connect your phone to a wall charger > press and hold power and volume up for 10 seconds > let it charge for 1 or 2 hours > repair your phone with SUS

Count me in... I also faced the same problem from yesterday.. While playing hayday, my ZL just went boomm(literally).. Battery was at 80% and phone just kept restarting and whatever #hamza90 said, kept happening.... When I checked battery health in service test menu, it said "good, no need to replace"... guyss need ur help here...

Okk... Things got more worse now... If I unplug the charger, phone switches off by itself!!! Again I checked the battery life in service menu and it said the same,"good, no need to replace". Need ur help qickly guys...
