Currently Being ModeratedJul 1, 2010 6:03 AM (in response to SilverSwordZero)This is a pretty easy fix and it has been said here before. Do not restore from a backup, start with a clean installation, setup your email connectors (for fetch, not push!), re-sync your apps. etc.. Yeah, you are going to loose txt msgs, call history, etc., but this solution works.
I was one of those bashing 4.0 until I did a clean install, now the battery is back to normal. Amen!
Currently Being ModeratedJul 1, 2010 6:48 AM (in response to deadbolt67)Please refrain from acting like you are smarter and nobody reads. You are the one not reading. That doesn't fix it for everyone. For some it is the exchange server issues, some it is the restore as new, then there are those like me who have restored as new and done all the advice given here and do not have an exchange account yet still it drains.
Apple has re-contacted me and asked that I reinstall the battery logging app to further investigate. While draining the battery and then charging it overnight has helped my iphone it still has moments of mass drain especially when typing a simple email where it will drain up to 5% in just a minute or two. If I use the IMDB app it will drain up to 3% in the same short span and that is loading one movies info and reading, that is not doing a ton of searching.Custom PC, Windows 7
Currently Being ModeratedJul 1, 2010 8:15 AM (in response to SilverSwordZero)I have had my iphone 3gs for a year now and i just downloaded the new software. at first i was amazed by what it can do but when i woke up the following day i noticed my phone was dead. in a whole year this has never happened. now i notice that i cant even come close to a full day without charging my phone, infact it needs to be charged by noon time. this is such crap and apple needs to fix this!!!!!iphone 3gs, iOS 4
Currently Being ModeratedJul 1, 2010 9:37 AM (in response to PharmNerd)The exchange server configuration profile seemed to fix my problem. My phone's been on for 5 hours now and only at 75% (normal / pre ios 4)

Currently Being ModeratedJul 1, 2010 1:58 PM (in response to Jibsheet)I noticed the same notification stuff as well. I turned off all email push notifications and went to the advanced tab and selected manual for each specific email account (yahoo, exchange and gmail). I put the phone to sleep and sent myself an email to all three accounts. After I sent the email my phone vibrated and beeped, telling me there is a new email (just the yahoo). The phone was asleep with ALL email accounts (separately) set to manual. How can my phone, being asleep with all emails set to manual, get a push email? I deleted my yahoo, which seemed like the culprit, and added it again. This time when I sent the email as soon as I woke up the phone I received the email notification. ***???? Something is seriously wrong.
Also, I played angry birds for 10 minutes. My battery was at 41% when I started and when I was done it was at 31%. 10% battery loss in 10 minutes? Really??? It wasn't that bad in OS3.x when I was streaming my slingbox over 3G for the love of God!!!
I hope this gets solved quickly!!!iOS 4, 3GS

The exchange server configuration profile seemed to fix my problem. My phone's been on for 5 hours now and only at 75% (normal / pre ios 4)
The Exchange Profile (which is found at http://support.apple.com/kb/TS3398 -- in case anyone missed it) might have helped me a little, but I'm still seeing battery drain. About 7hrs on standby, and my battery is more than half-drained.
Anecdotally, it seems like every time I feel like my battery is dying prematurely, it's when I turn on my device and there's a Facebook or Words With Friends notification staring me in the face (particularly Words With Friends). I wonder if there are still some lingering app and/or notification issues also involved here...
And, by the way, when I installed iOS4, it was by setting up as a new device. I've also had at least a couple complete battery drain / recharges.Custom Built PC, Windows 7, 8GB iPod Touch 2G
Currently Being ModeratedJul 1, 2010 8:47 PM (in response to PharmNerd)Just a follow up after installing the exchange profile I reset the usage meters and my iphone (3GS) usage now reads 17+ hours on standby with 5+ hours of usage. During this test period i left all apps open and did not close anything. The phone was used as normal. Just about to call it a night and my phone still has 15% battery.MacBook Pro, Mac OS X (10.6.4)
Currently Being ModeratedJul 2, 2010 2:58 AM (in response to gotee12)I agree! Apple need to put an off switch in settings to turn off the multitasking. It's far more important to me to have a battery that will last until I get home in the evening!Windows XP
Currently Being ModeratedJul 2, 2010 8:55 AM (in response to Sorclive)If you read through this massive forum topic, you'll realize that while there are many possible causes for the excessive battery drain, multitasking is not one of them. If multitasking is responsible for extra drain in any way, it's the location services paired with the multitasking. Location services can be turned off and it can be turned off on an app by app basis. If you have tried absolutely every other solution other than this then try turning locations off to see what happens. You lose "find my iPhone" if you completely turn them off though.Mac Pro, Mac OS X (10.4.6)
Currently Being ModeratedJul 2, 2010 9:07 AM (in response to SilverSwordZero)From parshath's posts, it sounds like Apple doesn't have the first idea what is causing this or why. I'm pretty nervous about going to iOS4 since my battery life is already marginal (seldom able to get through a day without running below 20%) and if it goes any faster I may as well not have an iPhone. OTOH, one can see the writing on the wall for OS3 being supported by apps as well. Rock and a hard place of technology, I guess.iPhone 3GS, iPhone OS 3.1.3
Currently Being ModeratedJul 2, 2010 9:27 AM (in response to PharmNerd)Just want to chime in and say that pharmnerds link:
"I suspect that solution to our problem is finally here.
Has made a significant difference so far it seems. Not sure if it was my iPhone finally working through all that it needed to after the update, as some have been saying that it just takes time. But I'm definitely experiencing an increase in battery performance after applying this fix. I'll report back after this day is done and see if that is still the case or just me being overly optimistic.iphone 3GS 16GB - iOS 4, Windows 7
Currently Being ModeratedJul 2, 2010 9:40 AM (in response to Adrius)After applying the Exchange Profile fix (http://support.apple.com/kb/TS3398) and turning off notifications from the Words with Friends app, I think I'm back to pre-iOS4 battery life.
Battery is at about 75%, six hours after charging overnight. This is actually with a fair amount of usage (us iPod Touch users don't have nearly as fancy usage meters, so I can't quantify exactly).
I have Exchange push ENABLED, Gmail set to fetch every 30min, and all other app notifications ENABLED (in my case: Facebook, Textfree, Comcast, & AVSForum).Custom Built PC, Windows 7, 8GB iPod Touch 2G
Currently Being ModeratedJul 3, 2010 9:47 PM (in response to SilverSwordZero)I have the same issue, i fully charged my phone yesterday, within 24 hours it was at 10%. The most i used it was once or twice i unlocked the screen to check if i had any messaged. in the past if i only had it on standby it would be probably around 75%. This has only started since upgradingIntel, Windows Vista, 64bit
Currently Being ModeratedJul 4, 2010 11:06 AM (in response to Nitro52)I'm also having this issue, and I did an experiment where I charged my phone to 100% and then turned the phone completely off. Within 24 hours, my phone had fully discharged! This was with phone completely off. Keep in mind that my phone before the ios4 upgrade could last 2 to 3 days on light to medium usage.
This is completely unacceptable. I've never had any battery operated anything that would lose it's charge while off in less than a day. Can some of you try doing what I did and see if you have the same results? All I did was forward my phone to my work phone and just left my iPhone off. See how much battery you have when you leave work...and remember to unforward your number afterwards.iOS 4
Currently Being ModeratedJul 4, 2010 8:17 PM (in response to Kenshinr)Same with my Itouch 2nd gen. This is completely unacceptable. I will not pay for a new battery or Iphone/Ipod after I have followed every instruction on extending battery life and my machine was working perfectly until the system upgrade - which I cannot undo! Apple please fix this problem.I Pod touch 2nd gen 8gb, iOS 4
