Battery issue

[Siddhartha1]

After the latest lollipop update my battery drains at once. It shows 75% and suddenly ph gets switched off. After restarting it does not comes on. But when i connect charger battery again starts charging from 70% and ph gets 100% charged within minutes... What to do... Should i go for a new battery?

Hi @Siddhartha1

Please, first run a backup of the device information as explained here.
Then try performing a system repair using PC Companion or Bridge for MAC. 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 Siddhartha1,

If you need Bridge for Mac instructions follow the below information.

And Bridge for Mac:
1. Launch Bridge for MAC without the handset connected.
2. On the Main Window select "Xperia > Repair Xperia Device".
3. Ensure the phone is charged and select "Ok" in the following window.
4. Select Continue on the following page.
5. Wait until the initialising step is finished the continue as below.
6 . Select your model of phone from the list that appears
7. Follow the connection steps that appear, ensuring that you are holding the relevant button down before during and after the connection phase until the update/repair begins.

Let us know if the issue continues after backing up and performing this task.

Hello,

Many pepole faced this problem with the battery. Read the messages below.

No solution so far.

Even rolling back to 4.4.4 doesn't recover the battery behavior (as I hoped).

It seems to be Sony hardware problem when Google's Lollipop kills the battery.

Hi @Siddhartha1

Seems that Google has taken on some measures about the fast battery drain after Lollipop update. Post number 1023 is an answer from google about the reported bug. Also you can check this information.
