iphone 5 os had a bug in the original version software that came with it, and updating would not fix it. What worked for me….
•Plug iphone into your computer
•go to itunes
•select your iphone
•click on Back up now
•click on Restore Iphone (it will delete all iphone os software and install new full os software which is the latest full version)
•Then click restore from your backup so it transfers over your apps and settings.
Now.....make sure ONLY the apps you want to notify you are turned on, turn off the others so they stop checking and use battery. Go to settings>>Notifications>>go through every app to make sure if you really want that app to keep checking for notifications or not. Turn it to OFF if not (takes up battery)
2nd make sure only the apps that you want navigation to work with are on, turn off the others. Go to settings>>general>>restrictions>>location services>> turn off all apps that you don't need or want to use GPS for your location (takes up battery). Many apps are just being nosy on your where abouts, turn those off. Only keep on the ones that you really need on like Google maps, Find my iphone, find my friends, these apps really are the important ones to help you find your way, someone or something from your location.
Before I fixed my iphone 5 I was only getting 4 hours of usage from a full charge, it was TERRIBLE! Now after I did all the above I get a full day without charging my iphone. So it was definitely a software issue and I am THRILLED with my Iphone 5 now. The battery is actually very good. You just have to restore/reinstall a clean version of the software and turn off the app notifications and GPS that you don't need all the time so they don't run in the background and use your battery .
Hope this helps
I think I've tried virtually every "fix" on this and other threads, restored as new for each update, etc. currently:
I reduced my emails to 2, a yahoo and exchange account, and set both to fetch at one hour intervals, reduced my screen brightness to 1/3 or less and I'm still only getting 4-5 hours of usage on WiFi/LTE. When I first got this phone (a launch 32gb version) I would get 4-5 hours on cell and 7-9 hours on wifi.
No overheating, no usage matching standby time, just crapply battery life...i've drained it to shut off, several times in a row...
I think i've pretty much ruled everything out except for hardware/bad batthery as I'm reluctant to have it replaced (even though I buy AppleCare+ for all my iDevices).
Any other suggestions?
@rfry09 Did you try restoring as New instead of putting your backup in. Try that 1st so there are no apps installed, see if that works, if it does work then the problem is one of your apps, if so you have to trouble shoot which app is causing the battery problem by installing one at a time with a test inbetween each one. If that does not work then I would certinenly say it's your iphone's hardware, take it to any Apple store in your area (no matter where you bought it) and they will replace it at no cost.
Yes, as I stated in my post I restored as new several times and am running with a bare minimum of very popoular apps, Facebook, Twitter etc. Have not tried going app by app by app, as I have neither the time or patience for that (frankly, we shouldn't have to do any of this for what we pay for these devices...)
I've taken it in to the Genuis bar before, and will do so again this week.
do I have to wipe everything first? Could I shut all apps from the multitask window and then reboot the device to test them out?
I ask because I have tried doing that, and not opening anything but the stock apple apps, to no avail or improvement, and wonder if that validates that its a hardware issue.
Thanks, I previously turned off notifications to all but essentials, anid turned off virtually all location services, and as I've said before,I'm now running fetch once per hour (which for me is borderline useless).
As to whether 6 hours is appropriate, if my battery life had not been significantly higher when I first got the phone (7-8 hours if primiarily on wifi, 4-5 hours if prImarily on cell) and if my phone were not returning wildly different and inconsisten results day to day, I would not be concerned. And if apple did not claim significantly better battery life, whic is supported by anecdotal evidence on this support forum ad other forums, I would not waste my time thinking about any of this...
But I thank you for your thoughts and suggestions!
Nate: I restored as new and downloaded my apps from the App Store (as opposed to sync'ing from iTunes via my PC) and reinstalled them one by one (although I'm now using barely 1/4 of the apps I used before), but I've seen no improvement in battery life. I get 5.5-6 hours max usage via my daily routine which is virually all wi-fi data, except for my short commute to/from work.
You stated that you were not sure that I was having a problem, indicating that you only ever got about 6 hours usagefrom your iPhone 5 and its predecessors. But Apple claims that the iPhone 5 is good for 8-10 of usage (under tightly controlled testing environments, I realize that) and other users on this forum and others have posted screen shots claiming, 8, 9 even 10 hours of usage on a single charge. And some claim that they did not get to those usage numbers by using their iPhone for ipod music play or streaming audio (i.e. screen off usage). How do you personally reconcile that?
I can live with 5.5-6 hours of usage on a charge, that gets me through most days without a problem, but on a heavy day on the road, without wifi, where my battery life (on cell) drops to 3.5-4 hours of usage i cannot make it through without a charge and when that happens, I have no place to plug in, that's when the issue of Apple's claimed battery life and other user's claims of 8-10 hours of usage bothers me....
All that said, I still have not gone into the Apple Store and demanded a replacement phone...
Nobody knows the secret energy drain on the update, not even the engineers but I discovered
this helps maintain battery juice with the 613 update. Hope it helps.
I upgraded to 613 last week from 511 and have found that the battery drain issue is real. I waited to upgrade for several reasons, but wanted better security. So, my 3gs phone drains in about 3 hours and like everyone else who has been advised,resetting this and that and turning off this and that is not a solution. I did discover though, while sitting through a 6 hour mariner game against the white soxyesterday, 16 innnings ! and mariners lost; was that If I set my : reset network settings", then it drains a charge at 1 % every 5 min, ratherthan 1 % per minute. This is with the screen saver turned off. If i black it out, it lastlonger; however, let me start using it again, and the drain is faster but not at 1% perminute. This being said, I called apple today, gave a report and hopefully they'llfix it. Its definetly a network software program issue. At least I found a temp solutionto maintain my battery life, somewhat. No iphone upgrade for me, will have to switch off if they cant solve this. Hope this helps.
I managed to fix my iphone 5 battery drain without deleting my apps!
I was about to return my new phone back to Verizon!!
My battery used to drain down to 30% in 3-4 hours !!
Now I have my phone battery around 65% after 24 hours of last charge and 3-4 hours of web browsing , texting ..etc!!
My LTE , bluetooth , wifi, location services are ALL ON !!
and AFTER the FIX !
All what I did is the following :-
Settings --> General --> Reset --> Reset all Settings (this will return all settings to factory default) this WILL NOT DELETE any APPS, Contacts, photos or SMS .
I disabled mail fetch
I deleted facebook app (not sure if this a potential cause), but I did all above three steps , which solved my battery issue immediately.
I think there a bud in IOS 6.1.x causing this problem when you upgrade from Iphone 4 to 5 through itunes , as this exact probelm happened with both T-Mobile iphone and Verizon iphone 5.
hope that helps!
