Guys, again, until the fix is out, i strongly suggest you tey this:

 

Plug your phone in itunes

Turn it off until itunes doesn't see it

Press both the lock and home buttons for 8 seconds

Then release the lock button but keep pressing de home button

 

This will reset from scratch and reinstall ios.

 

Important, do not restore your phone from back up after. Treat it like new an re-input every settings manually.

Will this completely erase all my contact ?  I want to try this fix but want to confirm if it will erase my contacts.

OK so further to my POST at 05-Nov-2011 12:07 above and as per recommendation from rogerfromfrance

I carried out the procedure and in two hours after that the battery is down to 75% from a full charge of 100%. That's an improvement from 6 hours to 8 hours of average battery hold. Before this the battery was loosing charge of 15% of total every hour and now its down to 12.5%

So is it really that much of an improvement? 2.5%/hour with no additional apps and no notifications no iCloud.

I will have to give it a day from morning to evening and see how it performs.

PsyGuy24  yes it will erase everything from your phone including the software and then you will be given the option to restore/upgrade in iTunes to IOS5 again.

Thanks dude, will give it a shot and see what´s up. Will post the results tomorrow.

Yes it will... But do a backup and just restore your contacts afterwards. Don't do full restore cause you'll restore your problem.

I was having the same issue with my Iphone 4. I went to

trialsandtribstech.blogspot.co m and my battery life has been amazing.

Just did a restore but after I do the procedure you posted, how can I restore ONLY my contacts? sorry but Im new in this thing of restoring and stuff, but due to the battery issue of **** I´ll need to learn.

Had an appointment today at the Genuis Bar(!) and told the guy about the battery issue.  He told me that it was definitley a software problem and that Apple were going to be releasing an update in the UK within the next week or two.  I mentioned to him about the various other ways people are trying to fix the problem and he assured me that there was no other way to resolve this issue other than installing the new software Apple will release.

I see 5.0.1beta2 is out so things are coming along. fwiw - I followed one of the suggestions here. The reset settings seems to have stopped whatever was the major culprit sucking down the battery. Overnight it dropped only 3% and now I am just past 36 hrs with 25% remaining. Not much for calling but lots of messaging yesterday, less today - a few messages, some music, couple of downloads and some browsing. Been on 3G and wifi, mostly wifi. Only thing I turned off is sending diagnostics to apple and I stopped a handful of things from going to the Notification Ctr and I only use iCloud for the find my phone, nothing else. For whatever reason, this is far better than before the reset.

If you have all your contacts backed up to icloud then no you will not lose your contacts.

I have an iPhone 4 upgraded to iOS5 and have been wondering why - all of a sudden - my battery life has gone to heck in a handbasket. It drops like a rock with only a little usage of location apps or internet access. Glad to see this thread.

I'm trying to understand the reset fix that is being written about - is it just basically re-installing the OS and only putting back the non-offending apps? Or, does it actually remove an error or corruption of the OS that is causing the drain on the battery?

I've uninstalled iCloud because it messed up my sync with Outlook and I haven't figured out how to avoid that.

I have just buhgt an iPhone 4 s. It is my fist iPhone ever, and I am very unhapp with the battery life. Thinking about returning it and going back to a droid.

The battery on it *****.

PUBCRAWLER13: please post about the experiences you had the rest of the day with the second beta 5.0.1, you mentioned seeing significant improvement and said you'd post another update in a day or so. Lots of people eagerly awaiting some more observations

Input on battery life. Until a update is issued I've increased batterylife significantly by turning off Bluetooth. Twelve hours after charging and several phone cals laterl I'm at 88% ! With Bluetooth on I would be under 50% at this time.

I also powered down this morning and will every few days just to reset.

I didn't get the chance to update this morning as I had hoped, but I've been using the phone steadily since about 8:30am, including about 2 hours' worth of some fairly graphically intensive games (Galaxy on Fire 2, Dark Meadow), lots of e-mails, steady texting and almost all location services on. I'm currently sitting on 59%.

it's still not quite as advertised, but prior to installing 501beta2 I would have been right around 20% or so. I can confidently say at this point that 5.0.1 is going to make most people quite happy, and there's still room for improvement.
