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 :)
