Q: iOS 5.0.1 - Made my iPhone 4S battery performance worse!

I wrote that BEFORE the update my battery life was 14-16 hours, now it's half of that after the update and that's because of my wrong expectations? Battery life went down for 50% after an update and that's my fault. Great logic.

I am having the same issue with battery life after the update. Also super slow download on 4G.

Has me asking, how is this an update:/

I too like everyone on this post went from great battery life to dead by 3pm after the upgrade.  I tried many of the suggestions in this post like turning off iCloud and location services.  That helped some but still no where close to where it was.

Someone said to restore the phone but erase it from the phone first.  So I did a complete reset from settings then plugged it into itunes and set it up like a new phone.  It is 6:50 now and I am still at 84%.  The battery life may even be better than before now.

If you are still having problems, give it a try.  Reset your phone from settings and once it looks like you are setting up a new phone, plug it into itunes and restore from a backup.

Complaining a non-issue? have you read the board at all? So many are experiencing horrible battery performance AFTER the update.

While waiting for Apple to figure what is wrong and offer a fix, I got this "Portable USB Charger - PC"

Oh O.K. sorry.

Yeah I have been having issues since October and wasn't trying to come across as cheerleading just hoping that in some way the steps that helped mine could or would help someone else. 

I agree there is a difference in people trying to help others and then some of the posts on here that are just bragging with no guidance on how to help us.

See ya

I'm curious if anyone gets near the 200 hours standby or are we all hardcore phone users? It just seems like some random figure thrown out there as I've never owned a phone even before smartphones that last more then 3-4 days without a charge.

Also based on your stats lack of being unable to turn off the 3G is a major factor. I now have iCloud and location settings off. It's improved CPU usage which is now between 10-20% whereas previous was about 80% but it hasn't made any difference to the battery. I'm on about 6-7 hours as long as I don't make any calls!

I had a iphone 3GS before and did get a couple of days usage off a single charge with everything turned on.

Normally when a phones plugged in as much as my 4s it's when the battery's on it's way out and you need a new one!

Guys I think I get it: the problem comes by manipulating some settings. Yesterday after a DFU restore on Itunes, my battery was excellent (20% lost on 14h during the night).

This morning, I changed some settings, (notifcations mainly, and locations shut off)

---> since I did this, my 4S is again leaking, hot as a fire, I could bake an egg on it!!!

For me, 5.1 just reacts badly to some change of settings.

---> DFU restore and then: DON'T touch!!!

I tried your method and it worked. I unplugged after a full recharge at 00:30 and by 09:45am (9.5hrs) the battery was still 100% with just about 7-8 min usage although after unplugging i went to sleep straight away.

thanks

I'll chin in here. My battery life has gotten MUCH worse after 5.1 update. 98% when I went to bed, in the morning after a 5min call, no other activitity, it has dropped to 53% by 10am.

I'd be lucky to make it thru a day if I actually used the phone like it was intended.

If location services are on than turn it off ,and turn off icloud too

Use least applications in notification centre.

Use cellular data when you need and turn of 3g until you don't need it.

Thanks but.....I'd didn't buy this phone to turn off all it's features.

Good !!  You are very welcome!  I know it seems redundant but it's worth it. 

Glad you got you phone back !!

Yaarab,

it gets better too...download BatteryDoctor and use it everytime you charge.

Now that it's better let your phone completely die and then do a compete charge with BatteryDoctor.

Yesterday I got up at 3:50 AM EST and at 11:00 PM EST (19 hours later) with normal use I still had 45% left!!

It is the best it has been since I bought the phone in Oct.

Reseting network from the "settings --> general --> reset" menu helped for my 3GS, now its back to normal battery usage :-)
