iPhone 3G Battery Life
July 16, 2008 – 12:51 pmSomething I noticed very quickly was how badly the battery can be hit by simple things on the iPhone 3G. Apple have a page of features that drain battery life, now problem is quite a few mean disabling features that you want to use like push email and wifi.
I did notice however that there are a couple that really make a huge difference, the first of these is using the GPS. You can turn it off by going to Settings > General and then turning it off as follows:
Then
Doing that when you don’t need the GPS will in effect double your battery life. Especially as the GPS will of very little use to you when your inside.
The other thing I’ve noticed that makes a big difference is tweaking the brightness settings, turning the general brightness down and turning off the auto brightness will help a lot. The screen on the iPhone 3G is a lot brighter than that off the old iPhone, side by side with the same settings it is pretty obvious.
