Iphone 4s Battery life WORSE with upgrade. Anyone else seeing same?

UPDATE ON ATTEMPTED FIX - IT WORKS!

I deleted and re-added my iCloud push email account yesterday and it seemed to improve battery life, but I was not entirely convinced at the time. Today, after 35 minutes of talk time, 5 hours of standby, and some 40-50 pushed emails (10.8 MB worth) my battery sits at 92%. It was charged to 100% and removed from the charger around 11am. It is now just after 4pm. That's half a day of normal usage for me. Prior to deleting and re-adding iCloud, my battery would be in the 70% range after a half day.

Based on my findings, I believe deleting and re-adding your iCloud account should help.

I feel like my battery life is worse as well!

AZREO,

First, I am sure happy you now have a phone that can be used without carrying around a car battery.

Second, thank you for giving what must have seemed like a stupid waste of time "Maybe" fix a try.

You have made my day, I feel so warm and fuzzy I may actually be able to turn of notifications for this particular thread... I think I will go practice spelling VINDICATION, just because it is not often I get to help some one have a much better day than they had yesterday.

Best regards Mr. AZREO

I deleted all of my email accounts (and my iCloud account) and re-added them. We'll see what happens tomorrow.

It might be worth looking at your Diagnostic for today vs before if you want to satisfy your self empirically. I don't know how long the iPhone keeps the diagnostic data if you choose not to send it but before I reset my mail accounts I had literally hundreds of error entries. Now I just get the odd low memory entry. The phone was simply working too hard to do something and not achieving it running down the battery.

OWRC,

That is interesting bit of information. I never looked at that data before.

My phone is working fine since I did all the magic tricks, "Restore as new", remove and re-install my e-mail.

I just looked at mine and there is a bunch of stuff in there. But I have no idea what any of it means or how much is too much.

The oldest date I found was 11-15 and the newest 11-17 (today). Just out of curiosity I did a "Hard Reboot", the Pwr-Button + Home Button thing. It did clear some items but the majority of it seemed to stay put. I don't think it is enough to worry about memory issues and my best guess from looking at memory used figures it is taking up about... oh heck I am guessing but maybe 1 megabyte tops.

Oh - by the way a "Hard Reboot" clears your usage data also.

OWRC - I would like to hear more about those low memory message you get. In my diagnostic data I couldn't find anything that was in any language I speak except for the rather sparsely place date stamps.

One more thing I have "Report Home" turned off. I too would like to know how would like to know how long the phone retains this data, does it just keep stacking up until the phone crashes in an out of memory condition. I know what kind of dumb-arse programmer would do something like that... but having worked in the programming field for most of my life I have seen such things get out into production and sometimes go unresolved for months while everyone sits around scratching their heads trying to figure out why the machine is behaving so strangely.

Day 2 after deleting and re-adding my iCloud account...

Usage: 1 Hour, 20 Minutes

Standby: 6 Hours, 49 Minutes

Cellular Data: 5.6 MB Sent / 15.8 MB Received

Battery sits at 81%. Day 1 seemed better, but I was hesitant. Today the improvement in battery life is very obvious and thrilling. I recommend everyone try this step before calling or posting. Delete all of your email accounts and then re-add them.

Before taking these steps, my batter would be down to 60% by this time of the day. Improvement is significant!

AZREO,

Those are pretty good battery statistics. I noticed that you are using "Cell - Data" and not WiFi. "Cell Data" is a power hungry son of a gun!!!

If you had WiFi at work (I assume your useage is at work, anyway...) you would do significantly better on your Battery score.

I am retired and most of my data comes via WiFi and my cell data as an example for today so far is 131kb sent and 286kb received. If I turned off WiFi and used Cell-Data my battery numbers would be about the same as yours or less for an equal amount of "Usage" time.

Now that you have your phone working all you have to do is talk your boss into installing WiFi. 😉

No change with battery life with upgrade. I charge 4s overnight, turn it on at 6:00 am and by 3:00 pm am at 60% after carrying it around in my pocket all day with NO USE. I'm afraid to use it in case i need the phone in an emergency situation. Don't know how fast it will drain if i actually use the device.

Well, I tried it (deleting an re-adding all of my email accounts, turning off push). While things were looking up yesterday morning, by then end of the day it seemed like I would hit the same number as the day before, about 6 hours of usage (in fact it almost appeared it would come in a little worse).

I am possibly fixed now. Looks like my culprit was Mobile Me, which I hadn't even noticed was turned on. I had a mobile me account I never used and ignored in the settings for whatever reason. Deleted MobileMe and 2% in one hour with no usage. That sounds WAY better. Thanks everyone for you help.

menace,

First glad you are up an running - "That a good thing"

But correct me if I am wrong but wasn't there some kind of warning when you first set up the iOS-5 or your iPhone 4S?

I seem to remember some pop-up that suggested deleting your "Mobile-me" stuff because of some strange conflict with iCloud and/or iOS5. Sorry I don't remember the specifics, when setting up a new phone I don't take notes assuming this is a just a new top of the line phone and that the installation software would take care of things like conflicting software and don't really expect it to turn into a beta or science project. "Silly me"!!!

Don't get me wrong I am an iPhone addicted end user that has out of anger with some of the initial iPhone problems that I have encountered tried other phones to no avail - once you use an iPhone all the others i.e. Droids seem like junk and for me this started with the iPhone 3S.

The point I am trying to make is Apple needs to clean up their initial release and update procedures to prevent the kind of problems you, others and myself have with the first release of each and every new iPhone (this just ain't anything new with them). It, for me, really detracts from the pleasure and expectations one expects from an Apple iPhone.

But - now that you are working I guess "All is well that ends well".

I am wondering if there is a relationship between Mobileiron and the new iOS. My battery actually seemed to improve with the iOS 5.0.1 update and then yesterday, my company implemented Mobileiron. My battery is now losing about 10%/hour and that is with me doing nothing. I have not added/removed or done anything differently since yesterday except install and have Mobileiron running. At this rate, I will have to charge my phone 2-3 times a day just to keep it running!

@Holman

Nope, no warnings. Like I said, I didn't even realize I had it on there. But if it continues like this, I'm happy in the end. Apple should really read this thread. It seems to definitely be a combination of PUSH services causing the issues.

lidapink,

There was another poster that mentioned "Mobileiron" and I think it is something the 'IT' folks use in conjunction with MS-Exchange.

Anyway I don't remember who the poster in this thread was but he removed and "manually" re-install the email his MS-Exchange mail client and is now getting far better battery life than he was getting before or after the 5.01 update and is now a happy camper. Do a search in this thread for mobileiron and then follow his/her tread to the point he got his phone working. You will be richly rewarded. 😉

There is an update scheduled soon from Apple to again address the battery issue call 5.0.2 but with the battery consumption you are experiencing I would wait to try the un-install, re-install trick. The heavy draw down that you are describing is NOT good for your batter, not to mention how aggravating it must be.
