What's wrong with my iphone 4 battery after ios 7 ?

Literally:
What's wrong with my iphone 4 battery after ios 7 ?
I've tried all tuning tricks - nothing changed.

This is not a current feature of any iphone, it never has been! I've heard that there are apps in the app store that allow you to transfer contacts but i'm not sure about anything else! Again you would need to look in the appstore, but again it will be very specific to that app if there are any at all!

Iphone 6 battery drain ios 8.1.2

Tormented by Battery Life
IOS 8.1.2 upgrade caused it
iPhone 6 64GB Grey battery constantly drains now, from full charge at 7 am it will die around 2 pm with minimum or no use.
It even drains while on standby, no serious culprits the phone was setup as new and all apps are upto date downloads form app store
The phone and apps worked fine before it,
Post update did the following so far
Soft Reset
Hard Reset with Restore all backup from cloud
Hard Reset with Restore all backup from pc
Restore again from pc with and without the restore backup
currently using a new setup with data synced once with icloud login
I have following tweaks already from various battery performance tweaks
Location Services to minimum (Google maps), no system services enabled
Background app refresh disabled
Reduce Motion is on (parallax effect disabled)
Notifications to minimum
Auto Brightness off and brightness is 25-30% from manual selection
Wifi and Bluetooth is usually off
Carrier Phone signal is usually ok but shows low signal in small percentages across email, phone but not too much its like 5%, 6% variants
iCloud is off
Autoupdate of apps is off
mail is on manual sync every 30 mins (4 accounts)
Can't see any obvious app which will cause this
Generally the drain increases if I use a heavy app like Google Navigation, or Marvel Content of Champions, gets hot too when using a heavy data app and battery can run flat in plain 1 hour of use
The full charge of the phone also takes longer and then discharges (with some emails (not on auto fetch), small use of whats app and 1 phone call) within 4-5 hours with tweaks 1-11 in place
Can anyone help, I have booked an appointment with genius but what if they say its just software even though I tried everything
Any genuine issue here?
Please don't redirect me to tweaks etc I have almost tried every blog out there on tweaks on battery and almost tried all combos

Addendum
Last night charging for around 3-4 hours only charged a dead phone by 55% then left it to charge overnight
Today the battery dropped from 6:15 am full charge to 53% at 10:38 am at time of writing this with
1 phone call out for 30 secs
1 incoming missed call,
Whatsapp fetched around 10 msgs
Email fetched around 20 ermail from 4 accounts but not viewed yet on phone

Solution to Iphone 5 battery drain iOS 6.02

Like many people I just bought a new Iphone 5 and noticed that the power drains very quickly compared to my previous Iphone 3GS, 4 and 4S. I tried many of the suggestions online such as turning off wireless, brightness, deleting this and that. I even tried to downgrade to ios 6.0.1 which failed as an error message showed up.
Then I came across a youtube that solve it, the link is at http://www.youtube.com/watch?v=BkfU-OvQVp8
Warning: Before you do anthing, read the backup/restore info in the end of this message
Solution
Basically what you need to do is
to go Settings->General->Reset->Erase all content and settings
Activate the phone as a NEW phone
Plug into itune and setup as a NEW phone
That's it!
Results
From that point on, my iphone 5 battery went back to normal. I turned on all my wireless, bluetooth, email push notifications, ie turn on all the smartphone functions as it should be. My 3G speed even improved tremendously from 500ms ping/1Mbps down/0.06 Mbps up to 99ms/9.51Mbps/0.34Mbps at the same location when I tested using speedtest.net app (several tests done. My data plan is still on 3G so I did not turn on the 4G or LTE functions of the iphone 5.
Backup/restore
Because you are setting up the phone as NEW, you cannot restore any data from itune. What you can do is to backup to icloud BEFORE carrying out the solution. This will backup your contacts/pictures/etc. These will then be downloaded back into the iphone from icloud after the phone is setup as new.
However, some Apps such as WhatsApp, Apps that have data that are not icloud supported will need to be backup and restore using other methods. This depends on the Apps.
Hence BE WARN, do your own backup and find your own restore methods because for this to work, you cannot use itune restore from backup function.
Does it work for you?
I hope this works for those Iphone users who is restoring their previous 3/3GS/4/4S backups from ituen into their new Iphone 5. I don't know if it works for totally new user of a new Iphone 5.
If this works for you, leave a comment here so that it will help others.

This is a follow-up. I called Apple Support. They had me go through a sequence of unplugging the phone from the computer, then rebooting the computer, unplugging and shutting down the phone, plugging in the phone while holding the Hold button to force a restore. It then finished the update and all is well. I wouldn't suggest trying this without having Support on the phone.

My iPhone 5 battery on iOS 7 is terrible, can anybody help???

The battery on my iPhone 5 was perfect when I upgraded to iOS 7. But one day it "died" at like 30%. I thought it was dead for 2 hrs., but then I tried turning it on later, and it just FLASHED on like nothing ever happened. I was pretty upset I couldn't use my phone for that long. When I was at a park, my phone suddenly died again. And I turned it on 10 minutes later and when it did turn on, it said 42% BATTERY, isn't that ridiculous?! I'm taking my iPhone to the apple store tomorrow to get this fixed, and I might have to get a new phone, who knows? Ever since I upgraded to iOS 7 3 months ago, it has "died" about maybe 10-15 times. Does anybody have a fix for this?? If you do, please share

IPhone 3GS battery life iOS 6.0.1

I updated my iPhone 3GS to iOS 6.0.1 and my battery life has gotten terrible. Use to get all day off a charge not it's dead in <6 hours. Any fixes?

I have the same issue w/ my 4s. My battery life was more than acceptable running iOS 6. I updated to iOS 6.0.1 & now my battery life is HORRIBLE!!! I just charged my phone & according to the usage, ie. Time Since Last Full Charge, was fully charged, yet it only said 94%. I shut my phone off after unplugging it & when I turned it back on, the battery read 97%... ?????
There is definitely something that needs to be addressed w/ the 6.0.1 update!! Really wish I hadn't gotten it!

Iphone 4 Battery problem ios 6.0.1

I bought an iphone 4 with ios 5.11 on ebay, there are few pixels do not working, the speaker is faulty and the power button is not working. Yesterday I updated to iOS 6.0.1, and now the battery is defective. The iphone boots again and again and when it comes again, then only at the socket. and the battery says 1 or 2% of the full battery symbol. I also restored it twice
there is a reason for an exchange at apple? (The warranty is expired)

There are loads of posts about this all over forums. It's an ios6 issue. If your battery was fine before ios6 then I doubt you need to replace it.

IPhone 4S Battery on iOS 5.1

I recently upgraded to 5.1 on my AT&T 32GB iPhone 4S. I have noticed that my usage time since last charge, taken at 1% battery level from a full charge, is about 4 hours and 45 minutes of usage and about 9 hours and 15 minutes of standby time. Is anyone getting battery drain this quickly? I have followed all the battery saving tips from restricting Ping and iAds to getting rid of most notifications and removing a lot of location services except for Maps and Safari. I also adjusted brightness to auto and deselected the "Send usage logs to Apple." Has anyone else tried anything to improve this battery life or is this the general amount of usage time people are getting?

I was skeptical; however, a suggestion from a user helped me alleviate my battery drain from iOS 5.1. Here's my verion:
Backup Data on Computer
Settings > Reset > "Erase All Content and Settings"
Setup as new device and DO NOT restore from backup
Most of my content is on iCloud or Gmail
Reload iCloud/other source data on iPhone
Sync apps from computer to iPhone
Enjoy!
It has worked for me so far!

IPad 2 AND iphone 4 battery draining FAST since IOS 6 update!

I have done EVERYTHING I can think of and that has been suggested all over the World Wide Web to improve the battery life of both my iPad 2 and iPhone 4 since the IOS 6 software update. Nothing works!!!! I am leaving town in a week, and I would like my phone to be working the way it did before.
Still taking suggestions to fix this.
APPLE please do something. I am losing faith, and I am also losing my desire to buy the new iPhone 5!
APPLE PLEASE HELP!
Thanks in advance!

Have you tried closing all apps? Double tab the Home button, then tap down on an icon and hold for about 3 seconds, until the icons are moving slightly. Click on the above every App.

IPhone 5 battery draining after iOS 6.0.2 update even on standby mode without wifi/ 3G at all.

My newly bought iPhone 5 was on iOS 6.0.1
everything worked fine and i had no wifi nor battery issues at all until I upgraded it to iOS 6.0.
i noticed some battery drainage even when i'm not using my phone at all it still drains 1-2% on standby mode with no wifi nor 3G at all in an hour,
If i use wifi it'll drain 4-5% in a few minutes time, more serious case when i use 3G, it's literally draining in EVERY SINGLE MINUTE.

Per designed, Wi-Fi will disconnect in sleep mode to save battery.
If you want Wi-Fi to stay connected even in sleep mode, plugin to a wall power socket.
No it's not "per design". It's not supposed to disconnect when locked/in sleep mode. The whole concept of having live notifications to work when your phone is locked is the standard for smartphones. Having this feature only accessable when pluging/charging the phone is rediculous and counter-productive. But it's good to know that I'm not the only one who has this issue. I hope all our issues are solved swiftly, good luck to you all

How to fix iPhone 4s battery drain on iOS 5.0.1

Please Read this entire post for my fix
FIRST OF ALL I MUST SAY THAT THE BATTERY THE 4S IS A BEAST!!!!!!!!!!
I would like to add two steps to this. I am a pure believer davidch you are unto something. I did all your steps and i went from 100% to 81% in two and a half hours...I was saying to myself "this mess don't work!" lol....BUT I decided to do a little investigating on my own.
I looked at my usage meter and realized that the actual USAGE TIME and STANDBY TIME were only 13 mins apart. However i knew for a fact the phone was sitting on the couch WITH THE SCREEN TURNED OFF next to me for 2 and a half hours. I may have picked it up once or twice after receiving a text and perhaps sending a text or two but that's it! My approximate REAL usage was around 5-10 mins.
Even tho I looked up in the top right corner and did not see the gps symbol, I was still curious. So i pulled up my multitasking menu (double tap home button) and noticed that after the reset there were multiple apps still available to be selected from. Not a surprise because we did a settings reset and not a complete content reset. My whole idea was to selectively remove app by app from the list until i found the culprit that was running in the background causing this fiasco (our fiasco).
IT WORKED!! I narrowed it down to the camera app. Which happened to be the last one that I eliminated. Then i started seeing the difference between my usage and standby meter grow larger and better even tho i was checking frequenly (about every 15 mins). I CLOSED THE CAMERA APP AT 12:30PM TODAY. At this time my battery has dropped down to 77%. AT 2:00 MY BATTERY LEVEL IS AT 76% What an improvement!!!!!!!! But was the camera app the problem??? NO NO NO NO NO
My guess is after the settings wipe all apps that were running ended up in a crash loop. Because after that i opened up all the apps that were running previously plus some extras and as of 2:41PM THE IPHONE IS STILL AT 76%. With approx. 3hrs of usage and over 5hrs of standby now. With about 20 apps running including the camera app!
I also did turn off siri raise to speak and did a reboot. Because after turning off RTS the infrared sensor on the front stays enabled until a reboot is executed. So here are my steps mixed with davidch's that worked for me.
For anyone new to the thread be sure to go through these steps to address the battery after updating to iOS 5.0.1:
1. Reset all settings (settings app-> general-> reset)
2 a. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
2 b. If you do not get the complete new setup screen with language setup and setup as new phone or restore from iTune/iCloud backup, be sure to go back to #1 and reset all settings again (it should happen the second time)
3. Turn off system location services timezone and iAd (settings -> location services -> system services)
4. Fully discharge battery (until you get the spinning wheel and it shuts off)
5. Fully recharge battery (overnight if possible)
6. Go to General->Siri....turn raise to speak off
7. Hold power and home together for a few seconds until the apple logo shows up. (Reboot)
8. Double tap home button exit all apps running and you should be good to do...
i didnt reboot after step 8 but maybe you should if you have a sprint or verizon iphone. 2:55 AND I AM STILL AT 76% I think i am in love all over again!!!!
Re: iPhone 4s Battery Life?

I have IPhone 4 and I updated the IOS to version 5. After the update the battery lasts about a day. After the update to 5.0.1 the battery lasts a day and a half. It is an improvement, but not as I expected.
The next step is to disable configuration options like:
- downgrade from 3G network to 2G
- disable Data services
- disable automatic clock
- disable location services
- use the phone only as a phone and nothing else.
I will come back to tell how much the battery lasts.
PS: the IPhone 4 is new so there is no problem with the battery itself.

I upgraded to iphone 4s and installed iOS 6 but now my battery life is significantly reduced. What can I do to fix this problem?

I upgraded to iphone 4s and installed iOS 6 but now my battery life is significantly reduced. What can I do to fix this problem?
I restored my settings my I got the new phone but I think I heard that with the iOS 6 updated that can be an issue and it is better to start from scratch rather than restore your settings.

reset all settings
settings- general- reset - reset all settings
now reconnect to wifi
settings - wifi- click network name - enter password - join
if issue persists backup info and restore via itunes
Peace, Clyde

IPhone 5 battery quickly losing charge after updating to ios 7.0.4

Just upgraded my iPhone 5 to the iOS 7 v and immediately started seeing the battery losing power. Has to be the upgrade. I old go evn 2 days before without recharging but now I have to recharge at least twice a day. What's up with this?

Yes. I seem to have fixed it, but not really. I erased all music from phone, and then manually managed a resynced eveything I wanted back on there. Interstingly, it didn't work the first two time and said (waiting to make changes) so I was freaking out. But the third time was the ticket and now we are good. Unfortunately, there is a bug, and until there is a real fix, my music that I have in itunes on my computer is not easy to get to the phone. It seems that many people have had the exact same issue since the updates. Hopefully it will fix itself in the next update. Thanks for help though.
