My battery life on my 4S with 5.0.1 has been absolutely atrocious. I was hoping 5.1 fixed the issue but your latest update doesn't sound promising. Look at this s***!
ouch dude, with those statistics im usually around 45% (running 5.0.1)
Yea...tell me about it! I miss my iPhone 4!

When I installed it was set-up as a new phone...nothing from back-up.
The log shows the same concerns that I have raised many times before...iMessage. Since this is beta software...this is about as far as I will go.
There are gonna be a few more beta's rolling out....I know Apple will find this bug.😉![]()
I do have faith in Apple...I sometimes get disappointed and angry, but they are not perfect. They still build great products...
The beta process is just that... a process. I think it's great they keep rolling out beta's. It's another opportunity to make it better.
UPDATE:
Well after a complete day and a re-charge cycle I hate to report that the battery drain has returned. My phone started to drop right after I removed from the charger. Here are my stats this AM:
2 hours 3 minutes standby
40 minutes of usage (mostly texts via iMessage and regular text/ and a 3 minute call no bluetooth) I can tell you without a doubt that I did not use the phone for 40 mins. Maybe 10 minutes at best. This usage problem is exactly what was happening before....unexplained usage.
Battery: 91%
If it is like before, usage will start to increase quickly and eventually be dead in a matter of a few hours.
Nothing is running except for what I reported....Phone app, message app, and settings.
Looks like Apple has more work to do....😡😡😡😡😡
I had this mystery usage too in the background that drained my battery. I turned off my iCloud backup, reset all my settings and restored. Hasn't been backed in the past several days. I get around 6 hours of usage and about 24 hours standby. May not be the best, but works good enough for me.
Like me
I normally get over 6 hours usage and 1 day, 3 hours standby on average. Thats with a fair amount of notifications and push on.
which i think is pretty good usage not much different to my 4.
So your getting 21hrs standby cause 1 day 3 hrs is 27 hrs minus the 6 hrs usage in that period equals 21. Apple quite 200 hrs standby which is 8.3 days. Your six hours is what exactly ? 3G surfing? that has a six hour battery spec and would run your battey down Just trying to understand where it all went cause if your not using it for much surely it'd last longer?
Has anyone ever tried to get the 200hr standby time, assume Apple would have had a phone with everything set to off and left it sitting in same place untouched for the duration. Anyone willing to try this? I can't leave mine alone as I'm completely addicted to it.
I think mine is about average, same as everyone else's and yes longer battery life can only be a good thing. Although I do manage to get through a whole day and recharge overnight.
I'm starting to wonder if this is a hardware issue that can't be fixed by updates. It's not hard to run a program that shows what using what power at what stage and time then adjust that setting. If it's not hardware then I think they are doing this on purpose so that you have a choice of jailbreak with bad battery life or take the battery fix and prob have all holes closed for jail breaking! I would be very surprised if there's not some kind of security update on 5.0.1 and the battery issue is still not fixed. Seems like hackers and apple are at a stale mate at the moment.
