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

Go back and read Pestav's post. He is suggesting that we DON'T want all of these old settings as they may be what are causing the problems. Backing up, restoring as a new phone, and then restoring your backed up settings defeats the idea behind what Pestav is suggesting that we do.

Well, whatever Pestav's post suggest it's not what I suggested. What I did, explained above, worked for me.

But by all means don't try it, that would certainly be defeatist. I'll just shut up and trundle along happily with my new and way better battery capacity...

Problem is if you restore the old backup of settings etc you just defeated the purpose of setting up as new. Ryan the real answer to your question is you will have to manually setup again those items again. You can try the restore in iTunes and let it restore the backup. THEN go to settings>general>reset> reset all settings. When the phone reboots select "set up as new". That will dump all the old settings and set up 5.1 defaults. But it will keep your apps and data intact. Then you go through and change the settings like you want manually. If that works you are good to go. Otherwise a fresh start and sync from iTunes may be the only option.

Well, that is exactly what the "Restore" button in iTunes does - first it restores the software and resets everything to factory settings, like a new phone, totally empty - only then it proceeds automatically to restore that "new" phone to the old settings and files from backup.

After giving ios 5.1 on my 4s a few days to 'break in', I decided it was breaking 'me' in. I definitely noticed a decrease in battery life compared to even 5.01, which wasn't too good either. So seeing it get worse, I needed to act.

- I charged phone to 100%

- Did a reset from itunes.

- restored from backup (not 'new phone' setup)

- Wifi off, Bluetooth off, Location Service off, 3G on.

- I have mail set to push, which I need on for work - via Exchange.

I'm officially happy happy. It's been 2 hours, of phone 'on' or 'standby', and 20 minutes of usage. Not much use, I know, but I'm still at 100% after 2 hours. I NEVER got performance like that.

Now, I've just enabled wifi, but with 'ask to join networks' off. If I stay at 100% for another 1/2 hour to hour, I'll then turn on Bluetooth also, just to see how much drain that has.

I think the 'ask to join networks' is one setting to keep off.

After a while of running well with both Wifi and Bluetooth enabled, I'll turn on Locaton Service, and let only Weather app be enabled.

But so far, so good. My 4S has never been this good on battery from the day I bought it.

After installing iOS 5.1 I'm getting the same battery life as before with one pretty major caveat that I didn't see in iOS 5.0 or 5.0.1:

After a full charge I'll disconnect from the charger and my battery will start to drop very rapidly. I'll lose about 5% in an hour with no use at all.

But after restarting my phone my battery will be back up to 100% and the battery will drain normally until the next full recharge, when I then need repeat the process again.

As i said in my previous post page 20, you need to restore complitely in iTunes and when the selection comes up to restore from backup or set up as new phone you need to select set up as new. The same thing applies on the phone itself. During first boot it asks questions about language, location, etc. It also asks wheter you want to restore from iCloud or iTunes backup or set up as new phone. Also here you select set up as new.

I had tons of app data (savegames, TomTom data, iPhone settings, WiFi passwords, Facebook account, mail accounts etc). Of course all of these got wiped and I had to start from scratch but it did make a huge difference and wasn't that much of a trouble for me considering the difference from my previous backups.

The reason you mustn't restore from any backups is that besides iPhone settings being somehow corrupt or not working properly and consuming battery there are also apps that might crash or not close properly. I remember monitoring my apps and for instance there was this app that monitored data usage. It was eating up battery even after closing it from multitasking bar and even after uninstalling it there was still some files that didn't delete and kept draining my battery.

OK I posted a battery fix a few pages back but after some time found out it was doing the same...

Well...I have completely revamped the process so here is the link to my post on here that WILL fix your iPhone ( iHope )

Not a good solution, I use my phone for business soI have a lot of settings set to connect to my office and network and documents/data related to business and so forth.

I have installed previous updates without doing any restore and any problems with my battery life.

As you all can see, this recent update has a bug.

And for those who are posting without any problems, why post at all unless you are just being an antagonist? We are looking for owners who have the same issues with this update so Apple will offer a fix to this problem.

Android does actually have 4G speeds, unlike Apple who doesn't care if you have 4G speeds. 4G is based on the carrier itself, not based on the OS. That's one of your faults. One of apple's lies, "Siri is smart!" No sorry she's actually stupid and is not very well programmed.

ME too.

Carged all night. took off charger at 6:00am Its now 3:19pm and had to plug it in twice now.

I tracked it as follows in sleep mode:

1:10@49%

1:30@44%

1:55@38%

2:24@30%

3:09@20%

Rough usage is 15%/hr or 6.5hrs MAX STANDBY!!!!!!!!!! Cmon.......Really

Powerade -

I can't help but dissect your mindless statement right there. I wil help you.

1. 'Android' doesn't have '4G speeds', the hardware that Android OS runs on does. Android runs on multiple platforms from 3G phones, 4G phones, refrigerators, printers, etc.

2. How would you know what Apple cares about ? You have the inside track at Apple or something ? My guess is your the sorta clown who has already knocked the 'iphone 5' before it's even designed. :-) (made myself chuckle there).

3. Your comments 'thats one of your faults' is a sorta generic make no-sense statement. Not sure what you were going for there. :-) (made myself chuckle again, but not laughing as much as in #2 above).

4. Apples lies saying Siri is smart ? Good grief dude, what are you supposed to say when marketing stuff ? Remember all the 'Droid does' ad's ? I bought into it 3 times (yes, I've had/have 3 android phones, and a tablet).

In reality, they should have said "Droid, well, sorta does some". But they wouldn't have sold too many phones.

5. I can't you referred to Siri as a she, then actually insulted her. You do know that Siri is just a Beta piece of software, and isn't really 'real' - yet, anyway.

6. I assume you are just a sort of anti-apple posting comments, which is fine. But comparing the 'lies' told by Apple vs. the 'lies' I've been told by Android, I'm afraid the Android world takes the cake. It was like 'Droid Does', the turns off, reboots, locks up, gets updates than ham more than cure . . . I could go on.

7. Only issue I have had with my Iphone 4S is determining the best approach towards battery life - other than that, it smokes all my Droids in terms of smoooooth performance, App's that are written for it and not ported over, and has much greater consistency between app's and screens.

Yes. Pretty much using it causes the battery problem. I did learn to turn all pushing stuff off which made it usable until this new update. Even on standbye with everything off drains the battery. I wish the apple lovers would stop blaming the users. Atleast apple finally admitted with this update they were fixing the battery issues

I would like to get a handle on whether being actually connected WiFi used less power then constantly 'searching' for WiFi. I'll try experimenting with that later. I agree with others that we shouldn't have to mess with the phones to get this straightened out. I just hope the Big A acknowledges there are still issues. What is frustrating is how good some folks battery is,and bad for others.

I agree, I'm tired of the "Apple lovers" saying it's the human with the phone that's the prob. I have numerous issues that will not be fixed and Apple knows of them....

But seriously let's put blame where it belongs...and totally fix the probem once and for all. I won't upgrade to 5.1 to many problems. My batterly life is not great, especially since I only use the phone for an ocassional text & picture....really not cool...but I bought the phone ...so I just have to deal with it. I can't even imagine how bad it would be if I talked, lol.

Of course, I have to complain. Previous updates, I haven't done anything except install the updates and the phone/battery was functioning as it is. With this 5.1 update, battery is draining quite fast.
