Battery draining on iOS 4.3.2 on iphone 4

Since i have updated the software to 4.3.2 on my iphpone4, the battery doesnt last at all. I check the battery at night, which is showing as 45% but in the morning, the phone is dead. I am using the phone exactly the same as it was on the previous versions. There is nothing changed, no apps downloaded. Is anyone having the same issue, or can anyone advise if there is a fix for this. This is a nightmare that every morning the phone is dischared and i have to charge it the first thing in the morning.


Please please please fix this, if this is an issue or advise.

Thanks.

I tried all the recommended "fixes" - Nothing changed. Battery has gone from good (iOS 4.3.1) to terrible (iOS 4.3.2)... I have done a full restore, after no change an additional reset... my battery last exactly 5 hours with 3G on - the equivelant of standby - during this time I made/received no calls, did not listen to music, no web browsing and read one new email!!!!!!!!

After the 4.3.1 update my iPhone 4 battery consumption was so high. Tried to do some tricks like removing apps on the multitasking bar, turning wi-fi off, etc. Finally I've read to do a Restore as New Phone. So here's what I did:

1. Sync

2. Back up phone

3.Restore as New Phone. Notes, calendars, contacs, settings are gone.

4.Then, do a Restore from Back-up. Put's everythng back to normal.


Result: Battery consumption is back to normal. I have the 4.3.2 update. Phone is much more responsive too and it doesn't get too warm under long usage particularly when brwosing the net.


Update your itunes first if you haven't done that yet.

Finally I bought a new iPhone 4 and I am more than Dissapointed ! I moved on from the original iPhone which is almost 4 years with the original battery to a new iPhone 4 and my battery keeps the same battery charge I have tried unistalling iTunes , Restoring the iPhone. Signing out from iTunes account, and so on nothing works... 1 % per 10 minutes is the best it could do. I did the mistake to update it from 4.3 to 4.3.2 the other day and today 4.3.3 is the same ****! I kind of ****** off, as old mac user and iPhone user this has to be the worst expirience I have ever encountered with an apple product due to faulty software. I don't care about apple collecting data where I go what I do, but I care in terms of the battery time I get. Fix it!

After weeks of trouble shooting, forum trolling and wanting to destroy the thing, I have finally got my iPhone 4 to last for 2 full days with normal use: calls, iPod, Web browsing and 4 email accounts (2 x Exchange, 1 x MobileMe (Find my iPhone) and 1 x Gmail with 15 minute fetch/push).


I restored the phone back to factory default with iOS 4.3.3 and did NOT restore personal backup. Instead I manually restored address book, music and photos, added the mail accounts and a few basic apps.


Based on this, it appears that one of my many apps was either using a lot of CPU/resources and/or polling something. I did clear all the apps but some still run in the background.

It certainly does appear to be the case that some apps run at full power in the background, even after being "closed" and that some apps seem to have memory leaks. These clearly aren't Apple's fault.


However, the OS doesn't offer us the tools to be able to look at app activity or to be able to shut down an app completely. iOS needs a proper appication management tool. This exists in the Jailbreak toolkit, but I don't want to jailbreak just to get something that should be native to a multi-tasking OS.

Been having mail problem on iPhone 3G - unable to receive mail in Inbox on phone unless I have Outlook open and receiving mail on the laptop. If Outlook open and mail appears, then it will automatically also appear in my iPhone Inbox. In attempting to 'fix' this I updated to iOS 4.3.3, and not only did the mail issue NOT get fixed, but I also now have this battery drain issue!


Sure seems like, as someone said, an infinite loop of checking mail... On the iPhone in Mail, the status bar at the bottom indicates that the sequence keeps repeating, with a 3 sec pause:


- Connecting...

- Checking for Mail...

- Updated 5/29/11


then pause for 3 seconds and start over.


I have tried the various suggestions of restore as a new phone, then sync, then restore from backup. Also, delete the mail account and recreate it. Nothing seems to help. I do notice that if I turn off PUSH, then the above sequence does not occur. Am I just witnessing PUSH every 3 seconds? This seems more like FETCH, but I'm no programmer.

OK, after almost 1 month after I got the iPhone 4 and tried as many as possible options, what I tried.


Signing out from app store: no change

Turning on and off Celluar data netword + 3G for 1 minute turning them back on : no change

Deleting my email accounts + setting push > fetch: no change

Hard reset the phone: no change

Turning off location and notification: no change

Reset the phone under General/Reset: no change

Restoring the phone to original firmware without using backup (several times) Both Mac and PC clean install on both machines new OS with new iTunes: no change


Maybe I've missed something. 1 day ago while I was drinking my coffee I read this post of a girl that she jailbroke her device (nothing new) and she installed this application under Cydia called "SysInfoPlus" and she saw that the is no root user logged in, she used another apple called "Mobile Terminal" or "Terminal" to login as root. So that's what I did I've hard reset the phone charged the battery to 100% took it off the charger and left it over night with the root logged in, for the first time since I have this phone it was 100% in the morning I've been playing with it yeseterday a lot and it seems to be doing good by my previous experience, but I still not sure that it's the iPhone 4 experince that users got before 4.3. I've been talking to friends with i4 and they say it's doing ok. Althought I am not a big fan of jailbreaking it seems to work. I have no idea what so ever what did the login as root changed to my phone but it works.
