Xperia Ray battery problem!

[explodingkatol]

So I bought an Xperia ray last October, and the battery life back then was pretty amazing. I could last about one and a half days on moderate usage (music for an hour or so, texting, a little wifi here and there), and about seven hours playing games from 100% to about 15%. But after I updated it to .64 just last March (if I'm right that's the build number?), the battery would drain at about 10% per hour with me technically doing nothing (so imagine me having to make calls or texting). I then upgraded to ICS hoping for at least a little change and it did get a bit better, but my battery would drain at 6% per hour without me doing anything.

I tried factory reset but the battery still drains at 6% per hour or something.

I switched off the wifi/bluetooth/gps/data, my phone is on silent, and I put the network mode to GSM only.

does this happen to anyone else? Is there any way I can fix it?

hey you can try to use JuiceDefender if you're not rooted or calibrate your battery (but it's kinda dangerous if you screw it up).. recently, i disabled my Fast Dormancy and it dramatically increased my battery life

-if this helped, hit thanks please

There are a lot of things you can do to get the most out of your battery. I would advise having a look at this:

Hi,

my Xperia ray worked perfectly for the first 6 months, after that I noticed huge battery drain. I changed the battery with a new one, larger capacity and it's the same. Over night, in 13 hours the battery drains to 15% although the phone is in idle state and wifi/gps/3g are all off, card unmounted, android version is the latest.
Looking at the battery stats, Cell standby and Phone idle are at 48%
I have reset the phone, reset to the factory settings, rewrote the software but it didn't help.
I'll next try to downgrade it to the factory version, android 2.3

ANy advice would be appreciated.
thanks,
Mihai
