For iPhone 5 users with battery drainage issues

You might have a faulty battery. I think a lot of us who were part of last year's first batch might have that problem, so I suggest that you get it checked out and replaced.

I was one of them. The replacement device (swapped in late June, manufactured in early June) is going OK - so far.
 
4 month old iPhone 5, fresh DFU installation of iOS7.0.4, most settings switched off, phone practically crippled in order to save battery power.

WiFi browsing, 100% - 95% gave me 46 minutes of browsing. Totally happy with that.
95%-50% - 139 minutes of browsing.
So from what started out looking like a very good battery life, I've seen 50% drain with just three hours of use. I look to be heading for my usual iOS7 battery usage of between 5.5 and 6 hours. On iOS6 I consistently got over 8.5 hours with exactly the same usage pattern.
Garbage.
What will my battery life be like when my battery ages?? My three year old iPhone 4 which has lived a very hard life still returns over 6 hours of usage per battery cycle!
 
I was part of the first batch of iPHone 5's which is known to have subpar batteries...I was 14 months into it and noticed my usage was not as good as when I first got the phone.

I was around 250 cycle count and down to 72-85% full charge capacity. It was acceptable for me but wanted more juice.

I just replaced my battery yesterday and now back to 98% full charge capacity. I think just over time, the battery full charge capacity decreases.

I'm thinking I will get another 1-2 hours of usage a day with the replaced battery on 7.0.4. Hopefully even more once 7.1 is released.

Now I should be good for another year. 🙂
 
I had pretty bad battery life with my iPhone 5 bought in December 2012. I tried every tip and trick that you can find on Macrumors. Then my On/Off button didn't worked and I got it replaced. The new iPhone came with iOS 6.1.4 and had bad battery life. I got around 4 to 5 hours max usage. Then I upgraded to iOS 7 and still got bad battery life.
Last try was to make a DFU restore. (I configured my phone every time after a reset as new phone)
Since couple days I get pretty good battery life. I even enabled parallax and got 6,5 hours of usage on my last charge. At the moment I have 4 hours and 50 minutes usage and 11,5 hours standby and have 38% left.

I've disabled most things that you find to save battery but I've enabled parallax.
Dunno if it has to do with my DFU restore but the first 1,5 weeks I had bad battery life after that.
 
Bought battery case, better than lowering brightness, disabling location services blabla... also better than replacing battery...

Disable every new feature just to gain 30-40 minutes (at best) ? Forget it

did you replace battery under warranty ?
 
This was my last charge. Now I try it with Parallax disabled.

But unfortunately not as good as having a nice thin light phone that fits well in hand and pocket.

I have a day 1 phone also. I shut off AirDrop and Frequent Locations, and that has helped a lot. Still not quite as good as 6, but MUCH noticably better.

Frequent Lications, air Drop ,Blustooth, are All huge bug battery drainers. If you don't use them turn them off. Your benefit in battery life will increase noticeably
