IOS 4.3.3 battery life has been significantly reduced

Do a hard reset on your phone - hold down the Sleep/Wake and Home buttons together until you see the Apple logo. Let go and let the phone restart.

My iPhone 4 have same battery problem. Hard reset dont work!

My iPhone has been having this issue depending on the software version. Some versions either have bad code for the battery usage, or they don't 'save power' in the same way for the same functions. In the course of 4 hours or talking for 1 minute, and the rest of the time not doing anything- it went down from 100% to 45%. I am going to try this when I get home, but you can give it a try too; do a RESTORE form iTunes. It is possible that the error isn't the coding, but the install going bad. However, if the problem remains after a restore; then I would lean in the direction of Apple rushing through the patch to address panicky people on the 'location issue' and not fully testing the patch.

I'll try to do the restore to see if it resolves, it was the only thing not done yet

I have lost about 40% of my battery life. Frankly, I am getting tired of this being an issue.

switching off location services appears to have significantly addressed the issue

Attempt restoring and setting up as new in iTunes. Make sure you backup all of your data via syncing first, as this will not return your data automatically.

So my iPhone battery *seems* fixed after a restore; but unlike other restores- it erased my lock-out code. Not sure if that is a feature, or a bug; but either way- AFTER RESTORE- put on your lock-code again!!!

Did you restore as new?

iPhone 4... Updated to 4.3.3 and today my Phone lasted 6 hours and I only made 1, 3 minute call ..

My phone is only 3 weeks old and I already want my blackberry back as these hardware issues stink.

Apple may sell a lot of these, but their iOS is not the best thing I've seen.

How do I fix this? FRUSTRATING !!!!

Can you post a capture of your status screen? Lasting only 6 hours on a 3 minute call makes no sense. Did you use the internet all day or location services?

how do I get the status screen ?

As for surfing ... none at all today. my location services are completely off (as I've been experiencing bad battery issues since I purchased this on 4.3.2)

Exchange PUSH is turned off ...

settings> general> usage

To get a screen capture press the home button and the power button at the same time. You will hear the camera shutter if successful.

I was actually looking for the usage screen to show your usage. lol.
