5.0.1 update--even worse battery life

After upgrading to 5.0.1 my iPhone is draining the battery even faster! Anyone else seeing this problem?

My battery life has also gotten SIGNIFICANTLY worse after "upgrade" to 5.0.1. 20min of web surfing this morning took it to 90% from a full charge. Yesterday very similar use only dropped it 1%. Come on Apple, I purchased this phone over other droid devices because I thought Apple had a higher quality standard.


Is there a way to go back to 5.0.0?

Guys! This is another disappointing move from Apple, and the fix is not a fix. Meantime, I recommend to use ycooreman's method at https://discussions.apple.com/thread/3457786?tstart=0, using battery doctor pro. I did a restore after my post eariler on, and it seems going a little bit improved. But the fix has to be from Apple, this is only temporary. Guys, if you want, have a try the method!

There is definitely something wonky with iOS 5.0.1 and battery life. I updated yesterday. Put my phone on the charger last night when I went to bed with about 25% battery remaining. Got up this morning and the phone was at 100%. Took the phone off the charger and walked out to the kitchen to make coffee. While the Keurig was brewing, I picked up the phone, and the battery was at 99%. Proceeded to use the phone to look at Facebook and read some articles and look at some emails, probably about 15-20 minutes of usage. The battery was now at 94%, which is way worse than before, after this much usage. I put the phone back on the charger while I got ready for work, and it was 100% when I took it off the charger and left my house. I drove to work, about a 15-20 minute drive, and the battery was at 98% when I arrived (the phone was not used while driving, all apps closed). I walked into my office and did a quick search to see if anyone else was having worse battery life, and I found this thread. I saw someone's suggestion to do a hard reset, which I did. The hard reset, which usually restarts the phone, caused it to power off completely. When I manually powered it back on, the battery was at 100%. But, the kicker is that I didn't put the phone on a charger at any point since leaving my house. How did the battery go from being 98% to 100% without being charged and by only doing a hard reset??? How is that even possible???
