Ok, from what i have seen there is a lot of location services being used
does it seem like to anyone else to utilize that if you want to use all the sweet features and notifications you will destroy your battery?

Idk, just a thought...
 
Considering all this is already available through jailbreaking... No, I really don't see a change in battery life.

I have tons more tweaks then announced today, and my battery is still perfectly fine. Unless your tweet a lot, with location services on with every tweet, it should be pretty close to the same. Only time will tell.
 
I had shocking battery life after restoring from my backup

I restored the ipsw again and this time setup as a new iPhone and my battery life is like iOS4 again (great)
 
My battery life was terrible in iOS 5 and I just reverted back, BUT realize that this is a beta, so they haven't optimized for battery life and performance, etc.

I don't think it will be significantly different in the final release. Besides, we don't know what they have cooked up for iPhone 5. ;)

You have to remember that the new implementation of notifications is not asking your phone to do anymore than it already did, it is just managing how it does it differently.

The major change is that it will have to have notification center queued notifications in memory, but that's minimal considering it was already remembering a unique badge count for all the apps that had unaddressed notifications anyway.

Additionally, the location services part of reminders actually shouldn't use any more power really. You have to realize the only way that the phone will realize you are moving is if it has to hand itself off to a new cell tower or it goes out of range of wifi. The phone already did those things, now it's just checking it against an active reminder with location stipulation. Depending on how precise they want to get, they may actively check gps to determine these conditions too, but I don't see that as an absolute necessity given a wifi database exists (although that would require wifi on).

Given that each iphone also incrementally improves battery life through a combination of power savings and battery size increases, I'd argue that the impact will be negligible, if there at all. Time will tell.

Does this mean you successfully downgraded from iOS 5 to 4.3.3?
 
I'm also finding that my battery is only slightly worse than 4.3.3 and considering I have been playing with it constantly the last 2 days, I'm not surprised it's worse.

Let's not forget this phone was designed by engineers that are pros at what they do. Given the space they were allowed to fit all the components into, I think it gets great battery life, even with location based services turned on.

NO.. it's most certainly not going to destroy your battery. Will it reduce run times, yes. But everything is a compromise and that is a great feature.

Finally the reason the iPhone gets very good battery life all comes down to just one thing. It's diminutive 3.5" display. The number one draw down on battery power of a phone or laptop is the display.

This is why Apple is so resistant to increase it's size. However market pressure is so great now with Androids running these big beautiful displays it appears that perhaps Apple will update the iPhone to a more modern display.
 
My battery life definitely seems worse with ios 5. I assume it will get better before final release.

And Please, no one say "of course! it's BETA!" We all know it is beta and it will be buggy. That doesn't mean we cannot talk about those bugs. That's how they get fixed.

Did anyone with battery issues try restoring the iPhone as new and seeing if battery improves? My iPhone with ios 5 is draining heavily but I restored from backup, so that might be it.

Actually, the poweramp draws waaaay more power. You can watch 10 hours of video sideloaded on an iphone but your talk time is about 6 hours (with the screen blacked out). :D
 
I haven't any noticeable drop in battery performance after upgrading. I don't turn on my % indicator or check my usage compulsively either, so.

You do bring up a good point, there are certain types of usage that will pull more power, but overall it's the display most of the time.

You are taking a really great approach. Most people don't realize it's simply an indicator, not a very specific gauge. It's only there to give us an approximate idea of the amount of charge remaining. Kind of like a gas gauge in a car. Just an indicator.
 
Seems worse and it gets hotter than hell just playing music, but I expect all that to improve with new betas.

Same here. My battery percentage was like a ticking clocking in iOS 5. I'm back to 4.1 for now (just to enjoy the extra speed and memory).

I'm hoping the issues I had with iOS 5 were "beta 1" issues. Maybe the next beta will be better optimized.
 
Got it installed last night just after midnight and when I got up in the morning ~8am it was down on less than 10%!

Only thing that might have killed it was I turned on reminder to test how they worked which I am guessing meanted it kept looking for its location.
 
This was happening to me as well. My iphone4 was getting extreamly hot and draining battery very fast. I also noticed when I got to work my speakers were going crazy with EDGE interferance (It sucks working in 2g land).

Anyway it seemed like the phone was constantly sending data. A lot more than normal.

My fix was to:
- Turn off notifications for weather (and associated location service)
- Turn off everything iCloud (herd it isn't working yet anyway ?)

Same as 4.3.3
- Push mail

Those are the only areas that I played with but that solved my issue.
 
I'll give mine another day to see if it settles down. It's not worth burning my battery up for.
 
I'm pretty sure it's the same, there's always a thread like this for every single freaking update. :rolleyes:
 
there are 2 reasons for battery issues in iOS5 beta:

1 - Reminders, location seems to be always on, which will drain power.

2 - Beta runs diagnostic stuff in the background for error logging, etc as part of beta testing.
 
My battery is like a ticking bomb! Not usual one to notice these things either.

Just glad it is still beta :D
