iPhone 4 battery shenanigans

[DaGaffer]

My iPhone (4 still running ios4) has suddenly started to drain its battery twice as fast. Literally started overnight. Anyone know if any external factors could be at play, or is this just to be expected with Apple shite? (Got the phone last May).

Nothing that I've heard on the grapevine.

Have you installed anything lately?

It could be reception issues, if a mast is down or has a fault in your area, your phone will use more battery signal searching. Check with your network operator first.

Are you keeping it in a colder environment? That flattens the battery pretty fast.

well my office is fucking freezing, but I doubt its that. I don't think its reception thing either as its draining just as fast at home as work. I haven't really installed any new apps that could account for the problem either; in fact the iStat app I installed yesterday to see if there were any processes causing havoc isn't showing anything untoward, in fact iStat itself is using the largest amount of active memory of all the processes shown, end even then its not that much. I'm leaning towards the theory the battery itself is a dud. Which is a pain in the arse.

You didnt manage to completely discharge it somehow?

Maybe you left it switched on, that will drain the battery. Tomorrow try kepping it switched off all day and see if that improves the life of the battery, i'm thinking it will

but hey, what do i know?

Only thing I can think of then is data use increase. It could be trying to send out crash reports to Apple or sync to iCloud if you've got those enabled.

Has your background changed? Use a black one to improve duration

Well, yes, that's when I realised there was a problem, when my fully charged phone was dead overnight.

Why didn't I think of that? Infinite battery life!

I was thinking the same. The logical culprit would be if our IT dept has dicked around with Exchange, but they say not and there's no obvious increase in data traffic on my O2 account (although I'm aware constant pinging wouldn't necessarily translate to lots of data), but if it was work I'd assume others would be affected and no-one else is. I don't use iCloud, I don't even use iTunes. The only app I've installed before it started to screw up was a Zapatag (rfid based loyalty thing) points log, so I dumped that to see if it was the culprit. Seems not.

I've had the same background for over a month and the battery usage was fine until 2-3 days ago.
