Q: iPhone 5 battery life is way worse than iPhone 4

SO I charged my phone all knight to 100%. Un plugged at 630 am ish. Now at 930 am I have 60% battery left after 1.5 hrs usage and 3 hr 13 min standby time. This is total crap!! I love apple but I am disappointed.

seems about average, slightly worse then the average perhaps. all depends on whats running

I wonder if the competition users such as Samsung Galaxy S 3 on AT&T network with weak cell signal are affected the same as iphone 5 as far as battery life goes. Maybe someone has a friend who can test it out by shutting off their wifi and trying to go a full day on AT&T network signal? Just a thought, thinking that maybe this whole 4G/LTE jump is just too early for the new phones to even have a chance to work at the batteries full potential because the network provided is so shotty right now because of AT&T still being in the 4G/LTE building phase and will only get better over time?

Hey guys I know this is going to sound strange but today I started closing out the 'Settings' app (in the task switcher) each time I use it, and my battery has been draining a lot slower.  Try it out and let us know your results.

I THINK I FIXED THIS PROBLEM.

At least for me.  Here is the procedure I used.  Checking the "USAGE" screen, I noticed that my "usage" time was way higher than I was actually using the phone.  In effect, the phone was "ON" all the time.  One hour after a full recharge, I had already used 11% of battery even though the phone had been off.

I started turning things off until this "USAGE" counter stopped incrementing when the phone was off.  By a process of elimination, I found the culprit:  PUSH from iCloud.

To turn this off:  Settings ->  Mail, Contacts, Calendars -> Fetch New Data -> Advanced -> iCloud

Select "Manual"

This will TURN OFF iCloud push but it solved my battery problem. 

I have no idea why this worked but I assume it's some sort of bug.  This did not happen with my old iPhone 4.

I note that others have fingered iCloud sync as a culprit also.

IF YOU ARE HAVING REALLY CRAPPY battery performance, I strongly suggest you take a look at your "USAGE" data and compare it to actual.  If it's much higher, then this becomes your litumus test to figure out what's going on.

My battery is now at 98% after 3 hours of standby and 16 minutes of "Usage."  This is very similar to what I saw on my iPhone 4 so I'm thinking I've fixed the problem.  Most telling, my mystery "Usage" is gone.

Alex,

Were you having LTE or 3G enabled at that time or was it just WiFi? Other sources of "usage" being counted even when your phone's screen is off could be playing music or using apps that really do something in the background (such as WhatsApp, Skype, GPS apps).

Sorry man, but I already ran that test by deleting my entire iCloud account.  No effect on battery life.

I'm still think it's our cellular connection to Apple's infrastructure.. Can anyone else confirm this?

10 second roundtrip?! seems insanely high.

This is to the push.apple.com pool

That could be part of the problem, but like I said, we have several different battery problems here and there's no one silver bullet to cure it all, unfortunately.

I had all those email accounts including the icloud to set to push in the advanced menu, to no avail.

Update:

For those of you new to the board, I was one of those with battery problem like most of us here.  Draining 5% per hour on standby.  Waking up to 30-40% drained battery with no usage.  Tried many different suggestions posted here but nothing worked.

So, yesterday, I went to the Apple store to return my phone for good and use my "old" iPhone 4 until apple fix it.  I was thinking about going android or windows, even.

They gave me a new in retail box iPhone 5 to try it out one more time and after almost 8 hours of standby, this one held its charge at 100%!  I'm crossing my fingers, because i know Handsfull also though his problem had gone away with his replacement phone, but apparently didn't.

I will report back later with update when it reaches 1% or so.

I have 4 and 4S on iOS 6.  I will install netstat and see what happens.

@yuni

Ahh yes. I remember that day.  I was so happy.  Thinking that I finally got a phone that worked.  LOL.  I even look at my screenshot I took of it on my phone, because I still can't believe it went from that to what I'm running now.  Sad.

Also: no, I did not add/change/alter anything that would have changed my battery use (someone will ask this so I'm being preemptive)

@spyd4r

that app is disingenious.  wants me to pay on each unit as an in-app feature to get any info.  I don't mind paying $3, but that just irks me how he shows paid version screenshot and ...bait and switch

@ Handsfull,

LOL  don't jinx me.
