iPhone Battery Tip
Posted on August 3rd, 2008
Just a quick note about an interesting discovery made for great battery saving on your iPhone, if you’ve been lucky enough to get one :)
Over the last week my battery life was extremely poor but I’d also had quite a few slow downs and lock ups. What is interesting is even if the phone locks up, it seems to recover after a few seconds without a reboot. Well a couple days ago my phone started getting really hot and the battery was dying in about 2 hours with no use …. so I rebooted the phone.
You can do this by holding in the lock button + menu button for awhile either until it just reboots or you pick an option from the system menu that appears.
After rebooting my battery is now lasting almost a full 2 days – I think some background processes get locked up and even though the phone appears to be working “ok” it is sucking down the juice. Worked for me, might work for you :)

iPhone Battery Results
Posted on July 16th, 2008
The results are in! and well not really much I can say except that Wifi on the iPhone is what kills your battery.
The 3G on/off didn’t make too much difference, I found that although Edge may use less power – it takes so much longer to fetch data that you’re coming out even if not worse. This assumes you even have a 3G signal.
With Wifi turned off I could probably get 2 days out the phone before recharging.
Another tip for saving power – when I call it a night I turn on Airplane mode (disables all comms). I want to sleep not be bugged at night :)
