Upgrade to iOS 5 is causing a faster drain of the battery

After contemplating for a week, I finally decided to upgrade my iPhone 3Gs from 4.2.3 to iOS 5.0. After a very uneventful 20 minutes(I mean this in a nice way), my iPhone was upgraded to the newer and flashier iOS 5.0. There are alot of features bundled in this upgrade (200+) though I did notice that now my iPhone seems to be a bit sluggish compared to the previous iOS.

Another thing I noticed was that my phone's battery kept on draining out faster than before. Where previously I would charge my iPhone once a day, I was now doing it twice a day! The only reason I could put to this behaviour was the recent upgrade to iOS 5. Searching on the internet, I found lots of users having similar issues. The difference though, was that they were using the new iPhone 4S while I was using iPhone 3Gs. However, saying that, they both were running iOS 5. Bingo!

Some websites reported that the degraded battery life on iPhone 4S was due to a bug in the way Location Services was checking and setting the Time Zone. The bug resulted in Location Services doing this task abit too often, which resulted in the higher battery drain. Turning off the automatic setting of Time Zone in Location Services was a fix that many recommended.

I decided to give the same fix a go on my iPhone. The steps are listed below.
1. Open up Settings in your iPhone
2. Locate Location Services and then tap it to open it
3. Navigate to the end of the screen till you see System Services. Tap this to open it
4. In the screen that shows now, turn off Setting Time Zone by sliding the button beside it to OFF.
(for good measure, I turned off Location-Based iAds as well)

Doing the above restored my iPhone to the similar (if not same) battery life that I had before the upgrade.

The fix above should work for any iPhone running iOS 5.

Hope this brings relief to others that had batteries running empty sooner than expected.
