iOS upgrade at 6pm (to 4.2)

[Digger]

Is anyone else's device draining its own battery. I have a 2nd Gen Touch and ever since the previous update (from 3.3 to 4.o IIRC. Still the same problem after 4.2. I need to switch Airplane Mode on or the battery drains within a few hours. Of course Apple dont want to know except to offer me 10% off a Touch or iPad!!

Battery life for me has been poor. Down to 6 hours. Easily got over 10 hours before

Mine too

I said this earlier in the thread, I knew straight away because I watch the battery like a hawk. Maybe the battery has to be reset as per htc desire thread.

I'm not finding it that much different, if the battery is better I'd rather go back. Bloody printing was the main thing I wanted, to print out all my notes and such directly would have been a godsend.

Glad it's not just me.. Thought I had just got it into my head the battery was taking a kicking and it was just how it was, appears it is worse than before. Great.

Battery life on mine has been dire since the 'update', just wiped it to 'as new' and setting it all up from scratch again.

Same here. And it's not because I'm running apps in the background. Even with everything closed it will eat battery overnight by a significant factor over the pre 4.2.1 release.

Some people seem to think it's the 'find my ipad' function, but I had that working before anyway through mobile me.

My third major upgrade and each time it has been cured by wiping the iPhone and setting it up from fresh as a new one. A right PITA but I''ve gone from using 60% of the battery life overnight back to about 8%.

Something not quite right about those percentages. You mean 80%?

Nope, using... Mine wiped it's battery out overnight after the upgrade, it's gone back to what it usually uses after setting it up as a 'new' iPhone on 4.2 and putting everything I had before back on. The numbers aren't really important as everyone will use a different amount but the total wipe seems to fix the excessive battery drain.

I let mine run down to empty last night and left it on charge over night for 12+ hours. so i am hoping that it has improved with a long charge from empty.

fk. That's going to take hours. Thanks for the tip though.

[BliarOut]

Yup, it does! I'd love to find a quicker solution but haven't as yet. It seems that the restore process from a previous version of IOS carries across settings that hammer the battery whereas installing afresh doesn't.

Wipe it last thing at night and let it sync while you sleep and it's not *that* bad.

So is that Reset>Erase all content and settings?

[BliarOut]

Yup, take it all the way back to factory config so it boots up with the picture of the cable. If nothing else is working give it a go, it's been effective for me three times so far.

Battery life doesn't seem to be an issue with my old 3G, I guess it's a multi-tasking related issue?

[anonymous-user]

Have to say I have not noticed any change in battery life since the upgrade on my iPhone 4. I'll keep an eye on it now though.

[BliarOut]

Not sure, mine's a 3GS and each major upgrade has been a pain in terms of battery life. It might only be certain configurations that are affected, I can only say what mine does

If you're restoring it as an 'as new' iPhone, will it go back to the old battery problems if your the sync it with an old back up? Or are you manually installing all the apps individually?

[BliarOut]

Apps, pictures and music resync OK from iTunes/photo, the one thing you mustn't do is restore a previous version's backup back onto the phone. And yes, you lose all of your settings etc.

I find leaving gamecenter logged in uses up battery, so leave it logged out and it may improve things for you

Did a 'hard reset' 2 hours ago and I'm still showing 100% :keepsfingerscrossed:

[BliarOut]

If that bloody well sorts it :shakesfist:
