Why is my iPhone5 battery draining so fast, worse than my iphone4?

I was a little unclear in my above post. After charging the phone for 12 hours, the battery was at 100%. The next day it was mostly in standby for 8 hours and you can see the battery dropped to 47%.

It's in the wrong place for either an iPod or iPhone because it's an iOS 6 problem. I would suspect that the iPad can have the issue as well.

My personal experience says this is 90%+ related to cellular data, turn cellular data off and most of the problem goes away. Granted that's not something you want to do but just to isolate the issue try it. The other 5-10% seems like some process running in the background when in it shouldn't. If I turn off cellular, use wifi only and keep unused apps closed I get stellar battery life. Easily I think I can get two days with light usage. 24 hours in and I'm still over 60%.

It's ridiculous to suggest turnin cellular data of as it's a smartphone!

Try to turn the phone of and battery won't run out so quickly...

🙂

I followed ALL the battery saving tips. ALL. Cell off, wifi off, brightness to minimum, location services off, push off, notifications off, vibrate off, all what you could imagine off except the phone. Went to sleep with 60% and woke up next morning with 45%. I used to do this with the iPhone 4 and the battery wouldn't go down not even 2%.

Why they advertise the LTE so much if you can't use it for more than a couple of hours?

APPLE SHOULD GIVE PEOPLE THEIR FIRST CHANGE OF BATTERY FREE.

Or fix it.

Mine is terrible

the battery can't work for even 24 hours standby only. Yesterday at night I charged it until it became 100%, and today it's off because out of battery so less than 12 hours and I didn't use it at all that's really terrible

I am experiencing the same issue as others in this discussion. I tried doing a restore with no change in battery life. I noticed that when connected to Wifi that I didn't seem to have the poor battery life that I did when I was out and about. I also noticed that the phone was constantly warm even when it was locked and not doing anything. Saturday I was watching the battery life lose 1% almost every minute, so I turned off cellular data and the battery drain stopped, went from losing 2% in two minutes to 2% in two hours. The phone temperature also returned to normal. Testing on Sunday produced the same results. Seems pretty clear that at least in my case, this is a cellular data issue. Something is running draining battery and keeping the phone warm.

I haven't posted in a couple of weeks. I'm on 3rd phone and nothing has remedied the issue except for the above. I'm on iOS 6.01 now too. I think that if you have no LTE in area the phone will constantly look for it, even if disabled. Its how it handles 3G data. Luckily I'm in Minneapolis and LTE is coming soon. I think/hope that'll fix it.

Interesting... I don't have LTE in my area either and I have it turned off. It does seem like there must be something the phone is repeatedly searching for, because if it were sending data constantly over 3g my data cap would be reached pretty quickly and my data usage seems normal.

Searching for a LTE tower I believe doesn't use data so it would go undetected.

I think that I've tried everything that has been mentioned in this forum, except a Reset, with no success in extending battery life. What I just noticed is that my usage and standby time are exactly the same (16hrs 17 mins; 12% battery) This can't possibly be correct. If I actually was using the thing for 16hrs and 17 mins with 12% left, that would be great, but my phone spends most of the day in what should be stand by.

I'm in Minneapolis. And we just got LTE coverage. Just today. It appears it may have fixed my battery drain problem. Good luck.

FYI there is _NO_ fix for this. This is either a hardware problem with select phones or some very serious bug deeply ingrained in the iOS 6.0 & 6.0.1 operating system. I have used my phone on various 3G networks in six different countries now. I exchanged the phone once and I have done a DFU restore and tried the phone wiht no apps and iCloud disabled. The horendous battery drain is the same every time always no matter what if cellular data is turned on. Turrn cellular data off and battery life is fine. Apple has really screwed their customers on this one.

Both my partner and I took delivery of our new iPhone5's this past weekend and we are both experiencing rapid battery drain. I'm glad it's not just us. We will give Apple a chance to make this right with a new phone but if we continue to have the same problem with a new i5, I will return mine to Apple and dispute the credit card charge. This is completely unacceptable! My i4 can go nearly 2 days without needing a charge and I will go right back to using it. Apple - the i5 is an epic fail in my eyes!

Archer\'s Dad, quit being a drama queen with your "dispute the credit card charge". If you return the darn phone do you honestly think Apple is gonna tell you to suck it?! They have the absolute best customer service in the entire retail industry, and if you want your money back, you get up to 30 days to use the phone and then ask for such.
