Facing problems with abnormal battery % and shutdown ?

Are you facing the issue of abnormal battery % / sudden shutdowns  ?

 

Sample threads

Xperia S battery drops to 0%

Battery Issue 

Battery going from 25% to 1%.

xperia mini pro battery issue

Battery drops to 1% suddenly

My Ray battery always speed to zero after reaches 20%. Is my phone faulty?

Battery level drops to 1% suddenly - Xperia mini pro for the 3rd time

My Xperia ray battery drop from 23% to 1% and power off

Neo V ICS update, battery drops from 21% to 1%

My battery gauge is tricking me?

 

And so many others.

 

Solution

On Xperias with removable battery

Note the battery % . Take the battery out of your phone and re-insert it after 5 minutes or so. Switch it on and observe the battery%. See if there's any significant drop in battery % ( 5+ % or more ). Most probably this problem has been corrected.

 

 

 

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 Xperia Companion

 

Download Xperia Companion and install it. Do not connect your phone until you're asked to do so.

 

Launch Xperia Companion > Select Software repair > Follow the on-screen instructions it shows.

 

How to avoid this error in future

  1. This error is usually produced when the phone is left connected to the charger even after battery becomes full.So disconnect the charger as soon as the battery charging status becomes full [ ( settings > battery > full ) or ( settings > about phone > status > full) ]To help deal with it, install any app from google play that fires up any kind of alarm or notification whenever battery goes full.
  2. Avoid using apps that monitor / manage battery, task killers, android manager, battery savers. They usually harm more than they do good.
