So, basicaly what I did was next:
Reset settings on my phone, turned off auto time sync with location, turned off Location Services, and I`m turning off apps as soon as i finish with them so they don't stay on taskbar.
This way I managed to get my battery last whole day and charge it over nights for atleast 7-8 hrs. Everything else is turned on like WiFi, and mid to heavy use of phone.
I'm on my 2nd iPhone 5 now (6.02). This one is almost as bad as the last one in terms of battery life, though it doesn't get quite as hot. Last night I left it at 95% charged. When I woke up this morning it was down to 74%. There were no open or running apps on during the night. Location settings are all off (except for Find my Phone), Mail is on Manual, blah blah blah...usual suggestions for battery life all taken care of including staying signed out of the app store.
However, what is interesting is seeing the system processes that are running currently as I re-charge my phone with Battery Doctor on, in descending order of consumption:
One wonders why Bluetooth and Phone are consuming battery as I'm not currently making a call and Bluetooth is firmly off. I'm in a wifi zone right now, yet Network(3G) is consuming power. I have no apps whatsoever set to Push.
I got an iPhone 5 for christmas. Coming from a 3GS with iOS 6 i never had any battery issues. My new iPhone 5 lasts only a few hours. This is terrible. Even worse, i only have one fitting charging cable. All my old ones from my dozens of iDevices are useless for the iPhone 5.
Got to work at 09:30 today. All i did was two or three calls, 30 mins of internet radio, maybe 10 camera pictures and some light browsing and some notes.
Its 16:52 now, and my phone has been dead for about half an hour. And i cant charge it, because the old cables dont fit anymore.. Apple > WHY < ? I cant take any calls, no messages no nothing.. this is very very bad. I might go back to using my 3GS until this is fixed. Oh wait - i cant because my simcard had to be replaced ARGH!!
iPhone 5 is really nice, but without battery life, what is it good for?
i just noticed something:
Yesterday i had terrible battery life with my iPhone 5, the battery was drained before i finished my working day.
Last night i realized that i had plugged the iPhone 5s USB cable not into the iPhone Charger, but into the one that came with my iPad.
So i plugged the cable into the charger that came with the iPhone, and low and behold, it is now 8pm here in Bali, any my iPhone is at 58%, plugged from the charger this morning around 8am.
Are the problems people are having with their iPhones maybe related to chargers?
I checked my iCloud settings, everything is on, except mail, notes and passbook. Documents is on for WiFi only.
I am using 3G all day, no WiFi at all (because WiFi here is very slow compared to 3G)
Statistics say 2 hrs 12 mins of use, 11 hours, 47 minutes of standby. Battery now 57%... Hope this helps someone....
Very strange. I have had a the same battery issue as everyone else on the iPhone 5 and have tried every possible solution (IOS 6.0.2, DFU, limit ad tracking, e-mail to manual, backup from new, iCloud off, etc.). Battery life was terrible; around 7 hours on idle the phone would go from 100% to 0%, and be warm to touch! My issue seems to be around data being sent and received without any obvious reason, so I have had my phone with cellular switched to 'off' for the past month. I just read a few posts about the issue, seeing if anyone has had anyone success. One guy put his phone to Fetch on e-mail and the problem was solved. I did the same an hour ago and, incredibly, my problem has gone away!!!
Too early for a full success story but I will monitor now I have cellular switch back on.
I have no idea why but I'm not going to complain.
Give it a go if you read this.
There is definitely an issue with cellular. It's just crushing the battery life. Whether on LTE or 4G it doesn't make a difference. My biggest gripe is the fact that even in standby the battery drains constantly. The only way I can get somewhat decent battery life is when I'm connected to wifi all day, and it's rare I'm always connected to wifi.
I even had to spend another $35 on a second USB cable. I shouldn't have to purchase more products in order to keep this phone charged.
Tested the battery drain with standby last night. The results were horrible!
Charged phone to full 100% at 12:15am
-Mail set to fetch every 15 min - 8 imap accounts, 1POP
-Location services on- camera, find friends, google maps, maps, safari, Siri, find my iPhone, cell network search, compass calibration. Everything else off.
-iCloud on- contacts, calendars, reminders, notes, documents and data(use cellular data off)
At 8:30am the battery was at 46%!!!!! The phone was never touched.
One thing I noticed, is that even though wifi was on and connected, when in standby the phone goes back to using cellular. Once you unlock the phone for 1-2seconds, the wifi kicks back in.
So, all night it was using cellular data even though wifi was supposed to be on.
Even while in standby stats showed:
Usage: 3hrs, 45min
Standby: 8hrs, 30min
I haven't given up on Apple, as I have purchased yet another product.(iPad mini) But, I'm losing my mind with this phone. It's also a well known issue that 6.0.2 is a battery killer. Even those who weren't noticing a drain on earlier firmwares, they are now. Heck, my dad who is computer illiterate and knows nothing about apple stuff, heard on his radio show that there was a battery problem with the new iPhone 5. There is now 6+ threads on the app forums regarding the issue, and some of these threads have tons of replies. The main two threads have over 400,000 views. That's not even taking into consideration all the other Mac and Apple blogs/forums discussion battery problems, yet when anyone contacts Apple about the issue, they deny there is a problem. That is what bothers me.
Agreed. 6.02 here and similar settings to yourself. I didn't use my iPhone 5 all afternoon today. At around 3pm it was on 64% and when I checked it at 6.30pm it was down to 20%! I'm convinced that 3g is the issue.....I'm in a very weak 3g area and I suspect the phone is trying to find signal even though its in standby and in a wifi zone.
An update: phone was at 100% at 06:10 this morning and it's now 22:40 and been using it all day with cellular on. Battery power is at 55%!
I can't believe the problem is solved? Will monitor and update.
All: try changing e-mail accounts to fetch and then manual setting. It worked for me and I have tried everything in these forums.
Will update on if it's still OK in a couple of days.
Only problem now is that, while the phone is working as it should, I'm still annoyed at Apple's poor response to the problem. The iPhone 5 is not the same experience for me that it should have been. Will make me think twice before the next phone or iPad.
This is obviously a problem - is Apple really denying it? We have three iPhone 5s and one 4 in the family with varying battery situations.
My wife's is not draining as quickly as mine. She is at 6.0 (10A405) and I am at 6.0.2 She had light to moderate use for two days and it is still a 21% and has no complaints. Mine plummets with almost no use at all - rendering a very useless device. My daughter is at 6.0.2 and hers is not draining as quickly as mine, while she has heavy use. Still she says the 6.0.2 upgrade caused additional battery drain.
The 4 battery lasts all day with heavy use.
I am very disappointed with Apple. First the map App and now this. I wonder what will happen to that $520/share price if this does not get resolved within the next week or so.
