My wife's iPhone 4 has massive battery drain issues. It seems to have got worse on each update.
The phone is currently on 6.1.3 (10B329).
I bought a replacement battery thinking it was that, but no dice. So I then took the OEM battery from my phone and put it into her phone knowing it is a good battery, but in 22 minutes it has gone from 46% to 40%.
This battery drain isn't confined to usage either. Discharge remains the same on standby. The battery doesn't last 8hrs on the phone.
I have checked the apps, and there is only 5 aftermarket apps installed. Phone is connected to wifi 90% of the time. Brightness was on full, now 60% but I do think there is an issue elsewhere.
Phone is not jailbroken. She doesn't want it JB as it will mess up her banking app.
Is there a component on the phone which could be causing the drain, or is this an issue with the 6.1.x updates.
I can honestly say that with each update after 6.0 the battery does last less. Anyone have a similar issue?
