Will doing a teathered restore to iOS 5.1.1 help my battery life?

OK I waited over a month to update my iPhone 4s to iOS 5.1.1. I did an OTA update (Which I think was my problem) I got hit with the battery drain bug that apparently comes with an OTA update of the OS.
I Did the following:
1. Full backup to iTunes
2. Did OTA upgrade
3. Restarted my phone
4. Turned off most of the notifications and locations
5. Turned off Siri Raise to Speak
6. Turned off Bluetooth
7. Turned off Wifi
8. Turned off Auto Send Diagnostics and Usage
9. Ran the phone all the down to dead
10. Plugged in and charged for about 11 hours
11. Reset all settings as new
11. Reset Network settings
Battery life is worse than I had with iOS 5.1 Which was pretty good. Before I updated to 5.1.1 I could go the whole day with normal usage for me, 5-10 phone calls, 20-25 texts, little bit of web surfing, check facebook a couple of times, check Twitter a couple of times. Play a few games, about 20 - 30 minutes max total over the day. Listen to a couple of podcasts. You know the normal things one does on a smartphone. At the end of the day I would be at 30 - 40 % left.
Once I updated to 5.1.1 I was going to get to 0% by 4 or 5 pm.
Is it helpful to do a restore as new connected to iTunes and just start over?
And if I do this can I then restore my apps, music etc from my back up or will that pull the battery drain bug back into the phone?

Haven't done anything different but battery life seems to be improving. I have run the battery down a couple of times, just normal use but the fast battery drain caused it go get below 20% by the time I would normally plug it in at night when I go to bed. Used to be 50 - 60 % at this point. And I have noticed over the past couple of days that the battery drain issues I was seeing seem to have stopped.
So hopefully the Reset All Settings routine along with a couple of full rechages reset the battery meter in the firmware and I am actually seeing the true battery charge and usage that the phone is getting.

IPad 2 with iOS 7.03 loses 12% of battery life in 24h. in Airplane Mode

Hi everyone,
I've always tried to maximize the battery life of my iPad; I fully discharge it and then fully charge all the time, and I don't do more than 1 full charge cicle per week.
In iOS 6 my iPad 2 was functioning nicely, with no noticeable battery drain in standby / sleep mode. The moment I upgraded to iOS 7 i noticed that my battery life was draining without using the iPad, about 1% per hour constantly.
I started to do a little bit of research. I made sure first that the iPad really goes to sleep when I close the smart cover.
I started to disable everything, one by one, removed all notifications, configured email to download only when I ask, disabled backgroun application refresh, closesd all applications before putting the iPad to sleep, etc.
I notice a little bit of improvement in terms of battery life in sleep mode but I still had a visible unacceptable battery drain in sleep mode.
I decided then to start real tests so I started to do the following:
- I fully charged it and fully chaged it
- when it reached 100% charge I kept it 2 more hours in charge
- I closed all apps and then I did a restart by pressing simultanously the home and the power buttons for more than 5 seconds
- I started the iPad, closed the smart cover to put it in sleep mode
- after 24 hours it was showing 87% so I lost 13%
Next test was similar but before putting the iPad to sleep I, put it in Airplane Mode. This time after 24 hours it was showing 88% so I lost 12%
One very weird thing that happened during this last test was that after 24h in Airplane Mode when I opened the lid, and without turning off the Airplane Mode I got a notification that there is a new software upgrade to iOS 7.04 waiting for me to install. REALLY in Airplane Mode . . . ???? I do not understand.
Have you noticed similar battery drain issues in iOS 7, did any of you performed similar tests ?
I consider 12% battery drain in 24 h. in sleep mode unacceptable, really unacceptable
My next test will be to turn it off for 24 hours to see how much is the battery draining when off.
Maybe Apple people have something to say. I have an appointment to the Genius bar today.
I'll keep you guys posted

Using the battery level meter in this manner is comparable to using your car's fuel gauge to calculate miles per gallon. The only thing that matters is the total amount of operating time from full charge to auto-shutdown.
Use the wall-mount charger that came with the iPad and charge overnight. Do NOT use an iPod/iPhone charger. Do NOT use a computer's USB port. Then, operate it normally until auto shut-down (ignore any low level alerts that may appear). An irony is that doing that test to determine the total operating time is also the procedure necessary to calibrate the battery level meter.
I'm not claiming that you do not have a problem. I am stating, however, that we don't yet know. If the above test does, in fact, indicate a problem, read this.
Also, according to Apple:
Use Your iPad Regularly
For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).
Elsewhere, Apple elaborates and explains that two half-discharges (or four quarter-discharges, etc.) equals one full discharge.

Any fix to the battery life issue from upgrading to IOS 6.0.2, as my battery life has gone from 2 days to 4 hours since 'upgrading'??

I purchased my Iphone 5 on the day of release, since then I have had a 2 day battery life on average, since upgrading to IOS 6.0.2, the battery struggles to last for 4 hours, is there any solution or fix?? If not any idea when this will be fixed?? Is there anyway to revert back to IOS 6.0.1?
HELP!!!

It is unlikely that this problem has anything to do with iOS 6.0.2. It is possible that the update process itself has caused some settings on your iPhone to become corrupted.
Here are some steps to deal with this:
1. Close all apps (use the app switcher; double tap home, press and hold an icon, click the "-" signs)
2. Go to Settings -> General -> Reset -> Reset All Settings. (Does NOT delete apps or any data; just resets network/iOS settings)
3. Wait for iPhone to restart.
4. Charge iPhone up to 100% and monitor.

Why is iOs 8 using so much more battery life on my 5c??

Ever since updating to iOs 8 with the supposed bug fixes, my 5c uses MUCH more battery life and I am NOT on it during the day at work except to make 4 -5 short phone calls!!! I hate it!! Wish I'd never updated. I have decreased screen brightness, turned off notifications for practically everything, and usually only play a little Solitaire and check FB for about 15 - 20 min. each evening. Also, FB isn't working at all since I've updated. I can open it and see old stuff but no new posts to FB. Come on, Apple!! This isn't what we wanted. Believe me, lesson learned. I won't update ever again to a new Os. This is ridiculous. I loved my 5c and it was working fabulously with great battery life!! I only bought my first iPhone 6 months ago and WAS in love with it UNTIL NOW!! Does anyone have any suggestions???

Basic troubleshooting steps clearly outlined in the User Guide are restart, reset, restore from backup, restore as new device.
Have you tried ALL the troubleshooting steps? If you have and you're still having problems, then you'll need to bring your phone into Apple for evaluation and possible exchange.
There is no supported way to downgrade the iOS.

HT1430 I have the Iphone 5 and just recently updated to IOS 6.1.3 and my battery life is just not what it was with the 6.1.2. I can start a day at 100% and in 6 to 7 hours be at 18%, (this actually occurred this past Monday) for no reason.

Hello, has anyone had problems with increase rate of battery life depletion? When I say increased rate I mean loosing maybe 80% in a 7 hour time frame while using the Iphone for nothing more than checking weather or stocks? This started after I went to the IOS 6.1.3. Before I could easily get 3 days out of the phone. Now I am wondering if it will hold the charge before I get home from work.

Hi imobl,
Thanks for your response, I forgot to add that the five 3uk sims we have in use, I have tried all of them none of them are recongnised non of them have pin codes, I even purchased four more sims Tmobile (original carrier) Vodaphone, 3 and giffgaff.

IOS 7.1.1 iPhone 5S Battery Life

Hi All,
I've googled my share of this feat. I'm curious to see someone elses take and opinion. I've had iOS 7.1.1 on my Verizon iPhone 5S since the update became available.
Ever since updating it, my battery life has gone down the drain. I'm currently at 1 hour 12 minutes of useage, and I am at 78%.
I have all the background refresh disabled, mail is manual (I have to go into Mail to have it handshake w the server to load new emails.).
I have location services disabled.
Notification Center is very limited, pretty much to texts and phone calls, etc.
Auto Brightness is on.
WiFi is only on when I'm in a WiFi area, such as work or home, otherwise it's turned off.
I used to work for Verizon Wireless, so I'm pretty good when it comes to the iPhone with trouble shooting. I've never experienced battery drain like this. I've done all but back it up, and restore as new, as I've seen people restoring from a back up, only fail to resolute the problem.
Can anyone with success story reply? Thanks in advance!

HT4528 I updated my iphone 5S to IOS 7.0 6 and the battery life is extremely short. Anyway to go back to the previous software. This is ridiculous

My battery life for my 5S is very short since updated to the 7.06. This is common and can I go back to the previous software?

Nope, it's not common at all. Why do you believe it to be 'common'?
And no, you cannot downgrade your iOS.

I have had my ipod touch for almost 2 years. When i turn ipod on it just has a white screen! nothing will show. i have restored it. i have tried everything help!

Ny ipod touch will not do anything. it just has a white screen on it. plz help!

- Try:
iOS: Not responding or does not turn on
- If not successful and you can't turn the iPod fully off, let the battery fully drain. After charging for at least an hour try the article again.
- If still problem that indicates a hardware problem and an appointment at the genius Bar of an Apple store is in order.

Why Does My iPhone 3GS with iOS 4.0.1 Cause Rapid Battery Drain

I upgraded my iPhone 3GS to iOS 4.0.1, and now the battery drains very rapidly---needs to be recharged after a few hours---and gets very warm. Before this, iOS 4.0 was fine (although slightly increased battery drain over 3.1.3).
I use Exchange with push and had no issues before iOS 4.0.1. This may be the culprit now because when I turn off "push," the battery drain appears to be normal (although not extensively tested yet). But, I also have MobileMe, Yahoo!, and Google email accounts set up.
Is this a new problem? Anyone else have this problem? How can this be fixed? Anyone have any ideas?

*Reposting this..had done the same thing earlier as well*
This is my observation from past 6 nights;
All 6 nights, charged my iPhone to max and then kept it in sleep/stand by. Not even a single call or mail checked...(11 pm to 6:30 am when my alarm rings)
1st & 2nd Nights, I had flight center, angry birds, twitter, facebook, mail, phone, sms, settings app open in the multi-tasking bar.
Battery drained from 100% to 83%
3rd and 4th nights, i had only twitter, facebook, mail, phone, sms
Battery drained from 100% to 92%
5th and 6th nights, I had nothing open
Battery drained from 100% to 93%
my mail is always in push enable setting to exchange and me account,
location always on, bluetooth always off. 3G off
I thought, the applications on multi tasking bar is actually not draining the battery, but looks like they are...might be a flaw in multi tasking api or may be from developer.
I hope to get an easy way to kill the apps and not let it go to multi tasking bar.

Why does my iPhone 4S ios7 sometimes brick even though it has battery life?

I know it sounds weird, but I have had this problem more than a few times since I upgraded my 4S to iOS 7. It will be working just fine, and then it will die. Kaput. Nada. Dead
It just did it within the past few hours. It was registering a 70% charge while I was taking pictures, and then it suddenly just bricked on me. I put it back on an AC charger as soon as I could (actually, the closest one was the one for my iPad Air), but it wouldn't even acknowledge that it was on the charger. No beep. No vibration. Nothing. I let it sit for about 10-15 minutes and then finally just held the power button down, and eventually after about a minute the bleeping thing gave me a white apple screen. FINALLY!! When the Apple screen went away, I looked at my home screen, and the battery was down to 40%. Really?? I didn't do anything!! It was freaking dead!!
Am I the only one with a psycho phone? Please, someone, say I'm not alone.

I usually hear about this when the user has done an over-the-air iOS update. The only way to back out of it is through a firmware update or "DFU."
Connect to a computer with internet access and the latest version of iTunes. Perform a backup first and you should be able to restore from the backup after DFU.
Press and hold both the sleep/wake button and the home button for ten seconds.
After ten seconds, continue holding the home button, but let go of the sleep/wake button.
The iPhone should go dark and you should see a popup on the computer. It should say, "iTunes has detected a device in Recovery Mode. . ." If there is no popup and the iPhone shows the Apple logo, you can immedeately try again. It often takes an experienced user two or three attempts before the device successfully enters recovery mode.
Follow all of the popups and a new version of iOS will be installed. If your issue was firmware, you should feel free to restore from the backup. If the issue returns, that means it was a software issue. In that case, you'll need to do another DFU and restore the iPhone as a new device.

Does anyone have a concrete way to extended the iPhone 5 battery life?

I've heard all of the rumors about not restoring your phone from an older backup, such as from an iPhone 4 like I did, but does that really work? And if so, how do I go about setting up my iPhone 5 as new, and then get all of my information back on to it. I don't really have enough space on iCloud to comfortably sync all of my contacts, pictures, and all of that shenanigans so what can I do? I've tried all of the basic settings stuff. (Location settings, WiFi, Bluetooth, and all of that good stuff.) None of it really worked. So if you guys have had any success with any sort of method let me know, please.
By the way, I have the Verizon verison of the phone if that makes any difference.
Thanks in advance!

Only concrete way is to use it less sorry see here every method possible has been tried

Does a Dark Desktop Image Help Save Battery Life?

I know this is a weird question.
But think about it: if you use a very bright desktop image, say something like this: http://img64.imageshack.us/img64/4540/deserttoyota24wf.jpg
and if, in the second case, you use a quite dark one, with a lot of "black" pixels that actually does give a lot less light (the one here is my desktop picture, a map with a light-rendering effect):
http://img64.imageshack.us/img64/8049/europewidefx7wq.jpg
1. does the darker desktop screen consume less battery power for the smaller amount of "glowing" pixels?
and, as I am asking stuipid questions,
2. does the darker screen help in prolonging your Powerbook screen's lifespan?
I have been asking myself these questions ever since I got my brandnew PB 17" HD (October 2005), and although they seam strange I am serious about it.
Thanks!
PowerBook G4 17" 1.67 HD + G4 QS 867 Mac OS X (10.4.5)

Your backligth seems to be white is'nt it ?
So to known how much you use electric power to switch a pixel from white to black, the best way is:
1) to turn off all your ligths in your house
2) to remember your electricity company counter index
3) mesure the time the powerbook is on
4) put your screen with a white background
5) change the background to black
6) run to the electricity company counter and write down the index
7) substract the start index from the end index
8) substract powerbook electric comsuption
9) divide this result by the number of pixel your LCD have it will give you the electric comsuption for one pixel.
Hope this help

HT4623 iOS 7 is so bad on battery life. I need to downgrade back to iOS 6.

I need to download iOS 6.1.4 for iPhone 5.

I see I'm not alone. IOS7 ***** on the iphone 4.
In order to get it IOS7 off I had to take a lost on some pictures, contacts, notes and a few other things on my Iphone 4 by restoring the phone thru a complete reset as if I just took it out the box.
When I connected to itunes it asked if i wanted to setup a new phone or restore from a backup. I restored from a back up from Sept 2012. It only had IOS 5.1.1.   I'm happy I got rid of IOS 7 on the iphone 4 but now the only replacement device I have is a 3gs.
My Iphone 4s got completely destroyed. I didn't want to purchase a 5 or 5s because every accessory I have won't be compatible unless i buy that adapter and I hear it doesn't work with all accessories.
THANKS APPLE FOR BEING SO INCONSIDERATE OFMY DOLLAR...
I'm so disappointed. APPLE ANYTHING IS NOT CHEAP! I can't get my 4s back to its glory prior to IOS7.
I'm moving forward with investigating other devices for a replacement.   Samsung is looking pretty good!
APPLE... YOU BROKE MY TRUST!

Will doing a teathered restore to iOS 5.1.1 help my battery life?
