If anyone is using location Reminders always remember to check them off when they're done otherwise your iPhone will keep using location services.
 
My battery life has been great after installing iOS 5

As for Reminders, I only had a location services icon in my status bar when I had "remind me" set to "when I arrive." Didn't drain my battery though
 
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.

1 - This is true if you have a reminder with a geo-fence (you set a location to remind you rather than a time). Interesting feature, but yeah, it makes the location services icon a worthless notification because it will always be on.

2 - Retail devices run the same collection and diagnostics. Betas these days aren't as different from retail builds as people think. Back in the day it was the case, but these days you want to be able to collect in-the-field diagnostic data even on retail devices.
 
Both my iPhone and iPad 2 have drained in one day which is something that never happens for me.
 
I've had shockingly bad, almost unbelievably bad battery life on my iPhone 4 with iOS 5. It must have been a glitch. I was listening to Pandora while at work for precisely 2 hours. I unplugged my headphones and a half hour later I felt my phone getting extremely hot in my pocket. A half hour later the battery was completely dead. I didn't do any heavy investigation yet, but I will do some experimenting tomorrow to try to identify the cause, and send Apple a bug report.

All I know is that with iOS 4 I could listen to Pandora over 3G for 5-6 hours and have the battery about 65%.
 
I dunno, i've actually had a not so bad experience with it. Yes it drains a bit more than 4.3 did but nothing drastic for me. Then again i restored as new, left notification benefits to only the main core apps and 2 third party ones, Bluetooth is left off and i'm not using Location in Reminders.

Otherwise everything else is on and syncing. Two full iCloud back ups, getting my emails, calendar, contacts pushed and fetched hourly depending on the account, Wi-Fi on, iPod, gaming etc

...and i've been doing fairly OK. Case in point; it's been taken off charge/idle for just over an hour now and i'm still at 100%

I've got 2 1/2 hour of usage, almost 9 hours standby and I'm still at 68%... Not great, but not bad!

I noticed this too, when streaming with either Slacker or Pandora. And on a new installation of iOS5, i did a side-by-side of slacker playback with my SO's iphone running 4.3.3 and the latter only dropped 6% in 1.5hrs over 3G while the iOS5-running phone dropped 19% in the same time. This was fresh, not restored from backup...not sure what to make of it. Going to give it one more day, and then revert, and wait for beta 2.
 
Reminder - No Location Option for Remind Me

I am running iOS 5 beta on my Verizon iPhone, and I do not see an option for LOCATIONS under the remind me sub-options for Reminders.

Has anyone else had this problem or issue?
 
I finally wen't back to a JB 4.3.3 late last night, in part because of battery drain/heat issues.
 
For what it's worth, deleting my iCloud account from the phone (and thus, turning iCloud syncing off) has returned my battery life back to the performance it had in iOS 4, if not better. I am still syncing my stuff via MobileMe, however, with no issue.

You'd think that there wouldn't be a difference, but there must be something new in the iCloud syncing protocol that has it constantly checking for changes or something along those lines. As soon as I disabled iCloud, my battery was back to having great life again. For anybody that's having battery issues, I'd suggest trying this and seeing if it makes a difference.

I'm sure this will be fixed in a future beta, but for now this seems to be a good workaround option.

I did this but battery life was still poor :confused:

So I listened to my iPhone again today, however I used local content rather than streaming. (I'm at 1995MB/2048MB for data use and still have a week left for this cycle.) I listened to music and podcasts via the Music app for 5 hours straight, with almost no interaction. At the end of the 5 hours, the battery was at 13%. I left it in my pocket for another hour and it was dead. This is, again, far worse than iOS 4. I would have probably had at least 75% left before. Tomorrow I will try disabling cellular data and listen to local content again.
 
that is definitely excessive drain. I haven't tested much with local content yet. Was yours a fresh install or did you restore from backup?
 
Battery Life, iCloud, and Running HOT

I upgraded to iOS 5 and used a backup as opposed to setting up a new phone. It ran fine for the first day and then suddenly I noticed it was running very hot when it was idle and the battery was draining extremely quickly. I couldn't figure out why and after several reboots I started looking into the various new aspects of iOS 5.

Once I took a look at iCloud under the setup screen I was certain I found the issue. It told me my login info was incorrect (the password for some reason was not entered or not entered correctly). I think the phone was constantly trying to communicate with iCloud in order to sync and it was stuck on a login attempt cycle. I re-entered my password and it seems to have fixed the problem.

If your iOS 5 phone is running hot and draining fast I would certainly look at anything that attempts to login from the background (especially iCloud). If it wasn't entered in properly the phone could be stuck in a loop.
 
Battery Drainage

Try turning off the "Automatically Send" Function a few people may have turned on when first setting up the beta, this funtion randomly send diagnostics and data to Apple and who knows how often that might be?
, go to
SETTINGS>ABOUT>DIAGNOSTICS AND USAGE>"DON'T SEND"

I just realized this maybe where I am going wrong not a hundred percent sure if it really works?

It was going great with me for a day or two, I haven't even opened the reminders app, but at some point last night it started just eating up battery. I probably have some app in the background or some pref changed, but if I am using it I can practically watch the percentage decrease. I didn't charge it over night, however, and it only went down like 5-8% the whole time I was asleep though ...
 
It's only a beta, so I wouldn't be surprised.

When the actual release comes, I'd expect it to be extremely stable and for the battery life to remain the same, if not get better.

I restored from a backup.

Day 3. I assumed, based on what I heard around here that it was because my phone was continuously sending data back to iCloud. Today I shut off cellular data. I listened to local content again for about 4-5 hours. Unfortunately I forgot to check the battery life at this point. I stopped listening to it for two hours, where it was just sitting in my pocket. I got home and a half hour later I looked at the battery life. It was at 23%. The problem is that I have WiFi at my house, and I didn't have WiFi disabled. So either the battery issue is unrelated to data use, or my phone did a TON of uploading and downloading on its own in the half hour that it was on my WiFi network.

I can't use much more data for another week (I don't want to buy another gig for a week of use), so I'll continue experimenting with local content. I'm going to do local content as-is on Monday, this time with Airplane mode on, rather than just turning off cell data. Later in the week I'll do a fresh install.
 
I restored my phone to iOS 5 using Xcode, set it up as a new phone in iTunes, then wiped it again (this time using iTunes to restore) and restored from my pre-iOS5 backup (which I grabbed from Time Machine). So far, my battery life has been on par with iOS 4, if not better. I'm not sure if wiping/restoring the second time would make any difference, but after setting it up as a new phone I realized I wanted all of my data/settings/texts/etc. so I went ahead and gave it a shot.

This screenshot is from just now - these 3+ hours have been of heavy texting (~200 texts), a fair bit of browsing, and a few phone calls (maybe ~20 minutes total). Oh, and downloading/updating about half a dozen apps, and reading ~600 RSS stories with Reeder.

I'm actually quite pleased.
