Battery life has been reduced with 4.2.1
Hi. I'm on the iPhone 4 and I was getting really good battery life before. I upgraded and now when I could get 1 hour and 15 minutes of use from 10% battery life on 2g now I get 40 minutes per 10% and my usage hasn't changed.
Any ideas? :$

I still havent noticed any sizable battery difference...but ive read so many threads across the web about this same issue. I know it sounds like a stretch, but is there a possibility that given the updates are optimized for 3G, that 2G usage is finally seeing a lesser power consumption advantage?
I dunno, it seems like my battery life has stayed around the same or just "slightly" (and i mean VERY slightly) less.

Mine is noticeable different. I took my phone off charge at 5:00 AM its not 3:30 PM and Im down to 24%
I have on Wifi and 3G and Bluetooth
I've checked Facebook and twitter today and I've made 4 phone calls each of maybe 5 mins a piece. and Ive been TXTing. 24% is bad!

I was having problems after the update as well. After deleting my Mobile Me account and adding it back along with adding my gmail and hotmail accounts which were previously forwarded to just the MobileMe account. My battery life is normal now.

Upon further review, I have noticed decreased battery life. In the morning I stream our local radio station and on 4.1, the battery would drain to about 81% over an hour and 15 minutes or so. Now with 4.2.1, the same amount of time goes down to about 77%. 4% is a significant drop if you ask me.

Doesn't findmyiphone keep tabs on your phone by using location services? So depending on how often it polls I can see it draining the battery. I found that 4.2 usage is really weird. When I first got it battery life was great a 10% increase over 4.1 but it actually seem to fluctuate even though the usage stays the same. I find that some days I get home at 6PM in the 60s when usually I'm in the 80s. I find it really peculiar, on my iPad though it's a trooper like always.
