Currently Being ModeratedSep 10, 2009 9:19 AM (in response to Exapp)Hello,
Had 2 x 3Gs iPhones me (32GB) and wife (16GB) we both work together and use the same Exchange 2007 server for PUSH email.
Up until today battery life was broadly similar except i use my phone more so had use battery quicker so by teatime hers shows 70-80% and mine 50-60% but that is after a full working day.
Upgraded both phones to OS3.1 last night. By lunchtime today mine was as low as 14% and wifes was still in mid 80s%.
Only difference is mine is 32GB models and wifes is 16GB model. Also I have a lot more folders in my exchange account.
Setting push to fetch every 15 minutes sorts but need Push to work...

Currently Being ModeratedSep 11, 2009 3:27 AM (in response to Exapp)After upgrading to 3.1, I am getting about 20% battery loss per hour with no calls or surfing. Not usable at all. I have Wi-Fi turned off and bluetooth and push turned on.iPhone 3Gs 32GB, iPhone OS 3.0.1, OS is 3.1 but they didn't give me that choice!
Currently Being ModeratedSep 11, 2009 6:24 AM (in response to ssaklad)Is there any way to downgrade or to get my battery life back?

Currently Being ModeratedSep 11, 2009 7:35 PM (in response to Exapp)My overall battery performance since upgrading to 3.1 has been extremely degraded. I don't think that Push email is the only culprit. Was on a redeye from SF-NY last night, and with the device in Airplane mode for five hours, and no use otherwise, My 32gb 3GS dropped from 40% to 19%. In 45 mins of very lite use on Edge to conserve battery, the phone died completely. In the space of typing this message, I have gone from 30% to 20%. Something bad seems wrong.iPhone 3GS, iPhone OS 3.0.1, Actually 3.1
Currently Being ModeratedSep 11, 2009 8:23 PM (in response to Exapp)I'm seeing similar problem on my 3GS 32G. battery life with 3.1 is MUCH shorter then with 3.0. I'm using same settings I used under 3.0--Wifi on, Bluetooth on, push email from MobileMe, and constant 3G cell connection, location services usually off). I thought 3.1 was suppose to improve battery life on 3GS!MacBook Pro, Mac OS X (10.6)
Currently Being ModeratedSep 14, 2009 12:27 AM (in response to Exapp)I've exactly the same issue. I have changed no settings or apps prior or since the upgrade from 3.01 to 3.1 and the battery life has gone from 3 day to a max of 5 hours! I'm not a heavy user, although I have always had push email, bluetooth and wi-fi on at all times. The phone now runs noticably hot and also takes longer to charge.
So in summary:
Everything was fine - lasted three days between charges - I have changed no settings or apps.
I upgraded to 3.1 on Friday and let the phone charge fully, and the phone was dead when I got home that night (I hadn't even made any phone calls).
It's now warm every time I touch it, and I have to charge it every five hours as the low battery warning comes up.
This needs sorted urgently!iPhone
Currently Being ModeratedSep 14, 2009 1:12 PM (in response to Exapp)After upgrading to 3.1, I noticed quick battery discharging and the phone was hot on the back. After days of troubleshooting I too narrowed it down to push email on my exchange account.

Currently Being ModeratedSep 15, 2009 5:37 AM (in response to Exapp)I have exactly the same problem as described here. In addition am roaming in Europe and just got notice that I had used 100GBP worth of data time in 4 hours.
Checking my activity I see if I turn push email on I am sending/receiving many MB every few minutes - even with no new emails coming my way. With push email off all this activity stopsIMac G5 17, iphone, time capsule, apple tv, Mac OS X (10.6.1), Iphone 3.1
Currently Being ModeratedSep 15, 2009 5:45 AM (in response to Exapp)While all the evidence points to PUSH as the cause of the problems, it cannot be push alone. I have a 32gb 3GS and have both Yahoo mail and Exchange mail set with Push to ON. I upgraded to 3.1 and have had no such battery problems. With moderate usage, I can easily get through the day with 40% remaining 6:30am - 11:00pm.
I have notifications set to off.
IMO, it appears to be some combination of push+???? The problem is trying to figure out the ????MacBook Pro 15", Mac OS X (10.5.6), iPhone 3GS - 32gb
Currently Being ModeratedSep 15, 2009 6:49 AM (in response to Jameson!)Im not seeing any of these battery issue's with my 32g 3GS, charged it this morning at 7am its now 14.46 and i have 98% battery, i have used ipod, wifi ,bluetooth, text and call today..
Yes the battery life is not as good as a normal mobile phone but hey this is no ordinary phone is it..
THink its all about conditioning the battery properly. look after it and it will last.MacBook Pro 13" 2009, Mac OS X (10.6), iPhone 3GS 3.1
Currently Being ModeratedSep 17, 2009 4:44 AM (in response to bah434x)Bah434x,
Just to re-iterate everything for you as you appear to be posting to defend apple not reading the original post.
Everyting on before upgrade to 3.1 that means bluetooth, exchange push, location services, WiFi and 3G. No change at all to any settings after upgrade to 3.1. No change except the OS upgrade form 3.0.1 to 3.1
Drastic battery life reduction after 3.1 to such an extent that phone will run out of battery and shut down by about 3pm. Turn off Exchange Push and set to fetch and the problem goes away.
Please tell me exactly how this is a battery conditioning issue?

Currently Being ModeratedSep 17, 2009 6:14 AM (in response to bah434x)Hello everyone. I've got amazing info for all in this thred or any in regards to battery drainage.
Befor yesterday my iPhone 16 gig black 3gs was draining battery from 100% to 50% or less than 50% in standby alone. Things I had on were 3g, all notifications, location services, and push & fetch 15 min.
Ok here is the real good stuff. 1. I've drained the battery 3 times till iPhone shut it self off then did 100% recharge each time. 2. Things I turned OFF wifi which is always off, location services, all notificatios except for 3 apps which are live poker, truphone, ebuddy. And of course Push which I then put all email to fetch 15 min.
3. 3g is always on. Ok now at 10:00pm last night I unplugged iPhone 3gs from charger @ 100% then put phone in standby as usual even when it drained over night from 100% to 50% or less with NO usage.
Ok today at 9:00 the phone is at a WHOPPING 90% with 12 fetched overnight email on standby. I must stress that overnight usage remains the same since September 10 when I did 3.1 update.
I do notice though that while typing this write now on my iPhone the percentage dropped from 90% to 83% but only while typing this on iPhone.
Issue for me is almost resolved but a simple message even as long as this and typed on iPhone 3gs 16 gig black shouldn't drop % like this so I'm almost there.Acer 6920 vista home premium sp2, Other OS, iPhone 3gs 16gig Black
Currently Being ModeratedSep 17, 2009 7:22 AM (in response to Exapp)I thought I would post this just as a bench mark for a new 3GS running 3.1. I picked up my new 32GB 3GS just last weekend from local AT&T corp. store (in-contract upgrade on existing line). Of course, the store set it up right then and there so when I got home, it was already activated. As soon as I got home, I sync'd it and upgraded to OS 3.1. At this point, I had not put a single app on it, nor even set up emails or altered any default settings.
After syncing, I set up my 3 IMAP mail accounts and my exchange account, and over the week I have put 52 apps on it (and have put and deleted about a dozen other free ones I wanted to check out). My general settings are:
All mail accounts on Fetch, manual checking
3G and location services ON
Wi-Fi always on (for my work and home wireless networks) with ask to Join OFF
Most recent usage, running the battery all the way to phone auto-power down (first time to run it this low):
usage - 6hr, 33min
standby - 1Day, 2hr
Usage = several voice calls (longest about 15min), only a couple of texts (all incoming, none sent), a few email checks and sends, listening to some news podcasts (Bass boost ON) over bluetooth (Jabra BT8040 ear piece - bluetooth ON only while listening or in the car), some web surfing, using QuickOffice and EverNote to edit some files, a couple of games (Tiger Woods, MicroPool)
So I put this up just as a reference, this is for a less than 1 week out-of-the-box 3GS running 3.1, having been upgraded essentially right out of the box.
From the posts herein with really low battery life, it sure is sounding like Push Mail is a big part of the problem? I don't use Push just because I spend most of my day at my computer at work, and my MBP is always available at home (and when I'm not at work, anything coming to my work accounts can just wait 'til I am!).2.53GHz MacBook Pro unibody, 2.8GHz 8Core Mac Pro 10GB RAM, 1TB HD, Mac OS X (10.6)
