Here's How to Stop the iPhone 4S Battery Drain

Over the weekend a friend came over proudly showing off sharing her brand new iPhone 4S (we would too, it's a beauty). She said the upgrade was a welcome one, except for one major issue plaguing her first major iPhone upgrade since the 3GS model: poor battery performance. She was reporting an issue with her battery draining faster than ever experienced before without any apps open or extraneous use. Her iPhone 4S was just discharging and running on empty way too fast to be attributed to anything she had done since adopting the phone. But there seems to be a very simple solution...

Until Apple releases a firmware/software update, new iPhone 4S users experiencing poor battery performance should give this one-toggle solution proposed by iDownload a try:

Go to Settings > Location Services > System Services to see if the purple location icon is displayed up in the status bar. If so, toggle off "Setting Time Zone." The arrow icon should now disappear.

According to iDownload, testing this simple settings change on 4 different iPhone 4s handsets, a 4G model, and even the 3GS resulted in improved battery life, as illustrated by Oliver Haslam's screenshot below:

Approximately 4 1/2 hours vs 7 1/2 hours is a huge difference.

Seems an easy bandage solution for now. We'd love to hear back from other iPhone 4S users experiencing the issue and report back if this toggle setting made a difference.
