Rapid battery drain

[bankieboy]

Hi,

This time last week, my Xperia U would last approx 2 days on a full charge. Since Tuesday of this week it is struggling to reach 8 hours - my usage is totally unchanged and I have neither installed nor uninstalled any apps. Power Management/battery shows Google Services 51%, Keypad 43% followed by wifi at 3% etc. Sync is disabled.

I have rebooted several times but phone currently says 91% battery, discharging and 43m 43s on battery.

Please help!!

Thanks - I will try that when I get home although phone says all software is up to date - fingers crossed!

Good luck.

Well that seems to have been a waste of time given that the Xperia U is not an option when asked to select device. 😞

You need to run SUS in compatibility mode with windows 7.

Sorry, I think you misunderstand. The programme is installed and running fine but, despite there being countless phones and tablets available to apply software updates to, the Xperia U is not available as an option to choose. Xperia M? Yes. Xperia Z? Yes. Tablets, clamshell phones? Yes. Xperia U? No. Would selecting a different model work and, if so, which one? My guess is the programme you directed me to does not support the Xperia U.

Of course it does,you need to run SUS in compatibility mode with windows 7.Do you know how to do that?You are on windows 8 or 8.1?
