iOS 4.3 causing battery drain

I upgraded my iPhone 4 to iOS 4.3. I went to bed last night and battery was about 50%. This morning I couldn't switch my iPhone 4 on! Battery was completely drained out! Currently recharging and observing...

Any chance that you read the rest of this thread?

Hi Modular! Thanks for posting the troubleshooting tips. I've gone down the list, fully charged my phone and then set it down at 100% charge while I slept. There were no apps running in the background. Within the 7 hours that I slept, the battery decreased from 100% to 64%. Prior to the iOS 4.3 update, battery depletion during that 7 hour time was typically 100% to 96%. To me, that demonstrates a definite problem. I appreciate your input and help with this issue though.

I'm making an appointment with a local Apple store today. I'm assuming we'll do the typical wipe-reset and see how it goes, or maybe replacing the phone. Either way, registering an in store appointment forces Apple to have a log of the issue, and the more it appears, hopefully it will be addressed.

I love all the "here we go again" threads. Guess what folks? You shouldn't have to wipe your darn phone every time there is an update. It's ridiculous. This is why I buy Apple products over MS products.

I for one, have never HAD this issue before, but this time, it's bad. As in 20% battery drain in 2 hours while doing nothing. It's unacceptable, and no fan boy needs to tell me, or anyone, wipe\reset and restore your phone. Do you think the average iPhone owner out there even knows about this? People like my own parents, older folks etc.?

Get a grip. There is a problem. Wiping my phone, and losing things like save game data, or anything else not easily restored, should not be the resolution, period.

Just because it happens EVERY time doesn't make any less of an issue. You'd be singing a different tune if you had to backup and restore your Mac with every software patch. Why should an iOS device be any different. Consumers expect upgrades to improve performance, not decrease it.

yes indeed i have noticed some battery drain issue...

I believe I did this order
- reset
- exchange account delete
- reset
- add exchange account

But I'm not exactly sure. Good luck!

Hi Tim. I've gone through those exact steps but found them to yield no change in the issue. Thank you though.

Hi,

I follow your problem since this morning because i was in the same case of you. After a reset of my phone the battery drain was inchanged.

But, this afternoon, i have looked that the gps was active. In preferences > Localisation > i found some programs that used gps. Since i stopped them, my battery not changed : only 1% since 4 hours.

Bye,

f you have a witness who looks like an arrow to the left of the battery, the
GPS is active and it's the reason for the high power consumption. It was my case.

No issues whatsoever here, so it's not universal.

I wonder if there are particular apps or configurations causing this.

...maybe Ping?

settings> service location (between notifications and operator)

Maybe you have a program that use gps (it was my case same with the program close)

It's an operating system update to a sophisticated and complex computer; there is always some risk, and a wipe and restore isn't that uncommon, whether it's a phone or a desktop.

It's very annoying, but it's a fact of life, unfortunately
