Singing the iPhone battery blues
"My iPhone's been draining awfully fast since I installed 3.0," I commented to a fellow TUAW blogger just a few days after the release of the iPhone 3.0 firmware. At first, I wanted to think it was my phone. But, my iPhone 3G wasn't even 90 days old at the time of the observation and I'd been able to keep it on standby for several days before it needed a charge. Now, I could barely make it through a 10-hour workday before rushing out to the car to hook it up to a power source.
Aaron Vronko of RapidRepair says that this isn't an isolated incident. The iPhone 3G may now deplete its energy supply in roughly two hours, and the first generation iPhone lasts less than a day. Vronko tells Macworld that the cause is most likely push notification placing a drain on the battery's reserves. The issue has also led to complaints on Apple's support forums.
I've definitely noticed the difference. If I leave myself logged into BeeJive IM while I'm at work, my phone drains much faster than it does if I'm logged out. Regular push mail notification from MobileMe doesn't affect the battery level all that much, even with the high volume of e-mail I receive through TUAW. So, to save on the battery for now, I'm avoiding the push applications as much as I can if I don't have a charger within reach.
Vronko believes that the 3.1 release will solve the battery issues.
