battery level indication stuck at 100%

megahard — Thu, 14 May 2015 09:45:35 GMT

I purchased this z2 just this december and its acting weird for a month now.. It took me awhile figuring out why the unit just shuts down even if the battery percentage was considerably high. The true percentage level only shows up after i press the little thingy on the side for reset.. Please help..

After booting at safe mode.. Tried to watch youtube to shave off some battery power.. But sadly, the percentage level did not move even one percent. Doesbthis confirm that its not a third party influenced problem?

Yes. Strange though,are you willing to perform a software repair?

Try force restarting the phone:

Press and hold the "Power Button" and "Volume Up" for 10 seconds until your Xperia vibrates 3 times. Now switch it on and observe the battery level.

I felt no vibrate pressing the up volume + power.. I also did the down volume+ power and it did start normal. And still no change on its behaviour even after watching again 13 minutes on youtube..

You may need to perform a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 80% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).

Hi,

The same here. Z3 Dual. Battery stuck at 50%.

On top, I am unable to start charging (original Sony charger + cable connected).

The same behaviour

- after repair via PCC

- booted in Safe mode.

- when switched off with Power + VolumeUp

- after orange button near sim pushed until 3 vibrations

I would take it to my local authorised service but I can't find any on the official Sony site...

Maybe I will downgrade to 4.4.4. (it would be my last attempt to repair it myself)

Any other advices?

After I downgraded to 4.4.4 there was no change.

Upgraded back to 5.0.2. No change.

Now, after a couple of days the battery is drained. No possibility to get it charged. (the connected charger causes occasional blinks of red notification diode and picture of empty battery on the display)

I think it's hardware problem - searching for authorized repair service.

Well this problem is for sure a software problem. You could try pressing the RESET botton next to the sim tray and then plug the device to a wall charger and leave it for few hours. Then Unplug it and turn it on. If that wont work i think you should do system Repair PC Companion.

Just a feedback to my problem (battery level stuck at 50%, battery not charging)...

I sent the phone to repair service and they have replaced the bad bad bad battery. It solved the problem.
