Hello. I'm facing the issue of abnormal battery % / sudden shutdowns. I've followed this steps unsucessfully : On Xperias with built in / embedded battery The way to force shutdown varies with phone. To find the correct way go to Support > select your phone > Select "User Guide" > From the contents given on the left side, select "Support and maintenance" and then choose "restarting and resetting" However on most phones, it's done by Press and hold the "Power" button and "Volume Up" button at the same time for 5 Seconds > Forced Restart ( One Vibration ) 10 Seconds > Forced Shutdown ( Three Vibrations ) Note the battery %. Force shutdown your phone by following the method above. Now switch it on and observe the battery %. See if there's any significant drop in % ( 5+ % or more ). Then most probably the problem has been solved. If any of the above didn't help then > Update / Repair your phone via PC Companion What can i do now ??? Please help.
