Help Battery Life Terrible With Giffgaff

[Shocky]

They use the O2 network, first night after changing from orange and the battery dropped 30% over night.

Everything was off, its not android os, what the hell is causing that?

Possible answer is the O2 (GiffGaff) signal on WCDMA (3G/UMTS) is worse for you than your previous Orange signal and therefore the handset is constantly trying to seek, and lock on to, a WCDMA signal that is marginal and causing the phone to constantly connect-disconnect-seek-connect-etc; which will cause a battery drain.

Try going to... Settings > Wireless and network > Mobile networks > Network mode > GSM mode... select this.

This will tell the phone to be content with GSM and stop it seeking WCDMA (UMTS) signal.

I'll try another firmware tonight, I know there are some new betas available.

Then see what it's like tonight, otherwise I'll switch back to Orange, with this kind of drain it was dead within 12 hours.

Firmware update made no difference, still dropped around 30% overnight, not sure what else too try.

Oh well, guess I stick with Orange.

What baseband is currently on the handset, Shocky? Did it get updated alongside the firmware?

I'd be sceptical signal could cause that much difference. More likely an errant app?

What does your battery usage chart look like?
