Serious battery issue.

Cometolon — Sat, 23 Jun 2012 22:00:29 GMT

Hi folks,

got my Xperia U 3 days ago, out of the box I used it till the battery was dead and charged it fully and did that process again.

Now yesterday I had 50% charge and it went from that to 0 in no time and turned of. Today it happened again.

Can someone help me please?

Thanks in advance.

charge your phone 100% -> press and hold volume up and power -> use it as you normally would, do NOT charge it at all

once you get to 10%

settings -> about phone -> battery use

take screenshots of the battery graph and the list of apps and services

tap on each item on the list and take screenshots or write down everything and post it here

remember that the more you sync the faster your battery will drain, also if you are using taskillers, battery apps or antivirus they will create a lot of issues and drain your battery faster

I don't use taskkillers or battery apps but there is a McAfee app pre-installed, should I maybe erase that?

Come to think of it, the battery indicator doesn't come to 10%, it goes from about 50% to switching off...

I'm going to wait untill the battery is fully charged untill I connect the device to my Mac.

Your help is greatly appreciated.

If the device can get to 10% I will to that, although I hope the repair will fix this issue.

Anyhow, I will get back to you, many thanks!

I'll try again tomorrow, it's getting late here in Belgium

BTW, does the battery need to be fully charged to do this process, I don't know where I got this assumption from?

So, up untill now the only change I made is deleting the McAfee app. Is this app pre-installed in all regions?

But ok, the battery has gotten from full to 27% untill now. If it reaches 10% should I still take those screenshots?

From http://service.mcafee.com/FAQDocument.aspx?lc=1033&id=TS101230

Will McAfee Mobile Security drain my battery faster?
Battery drain is negligible. With normal use, the device battery drains only 5 percent faster when McAfee Mobile Security is installed. If you have an Android tablet that is not push-enabled, your battery might drain faster because of higher data use. Also, your battery may drain faster if you have automatic scan enabled.

And bummer, around 20% the device turned off without warning.
