Re: sudden shut down battery problem, factory reset and SW update/repair did NOT help

how much do sony charge to replace the battery? i don't want to send it and find out that they charge an extortionate amount of money to replace it as it would then cost me to receive the phone back

 

my phone is still under guarantee but as far as i'm aware, sony have put in a clause so they don't have to replace the battery for any reason

No one can answer that question here on the forum, check with your local Xperia Care

Had exactly the same problem, tried everything that others recommended, no change.......... Sent the phone back to Sony for repair, 5 days later and one changed battery, phone is just like new!!
Check the warranty on your phones and send it back for repair!!

Hi. I had the same problems that you guys are listing up. Shutting down with 70% etc... Tried all I could find in this forum. PCC, reeboot etc... Without any luck. My sollution was to change the battery. My phone is like new.Notice that I changed it myself because I didn't have warranty any more. You will find good videos on YouTube and batteries on ebay. But use your warranty if you still got one.

Re: sudden shut down battery problem, factory reset and SW update/repair did NOT help

I have this same problem since LP upgrade

 

The battery will drain from 40% - 50% approx to 1% in seconds and the phone will shut down, put on charger for 10 mins and the battery shows 91% charge - now that can't be right, no issues on KK

 

There is something seriously wrong with how the battery level is monitored in LP, I have also read on the internet many other people with this issue not just Sony - even Nexus (Googles own hardware)

 

What can also trigger this event is a shutdown restart of the phone even when the battery is at 60%

 

This needs urgent attention

Re: sudden shut down battery problem, factory reset and SW update/repair did NOT help

I had the same problem and I went to a sony service center. As they told to me they re-flash firmware (something we can’t do by PCC or other tool as I know) and now my mobile is working as well as new. This is the only solution as far as I can see coz nothing help me beside that (like S/W updates, S/W repair, Factory reset)

 

Hope you got the answer.
