iPhone 4S Battery Drain Issue Could Be Time Zone Setting Bug

If you have a shiny new iPhone 4S as some of us do here at The Flickcast and you’ve experienced less-than-stellar battery life, this will be of interest to you. There’s been a few reports around the Internets, and elsewhere, that the iPhone 4S’s battery life leaves something to be desired.

Sure, it could have to do with the fact that it features a faster processor or that Siri is a bit power hungry. Or, as was postulated by the folks at iDownloadBlog, it could be the iPhone 4S’s Time Zone service that’s causing the problem.

Reportedly, a bug in iOS 5 (which ships on all iPhone 4S units) forces its location tracking feature to remain active much more than necessary which drains the phone’s battery far more quickly. Users can manually turn off the automatic time zone setting by going to Settings > General > Date & Time. Once there, toggling “Set Automatically” to “Off.”

We’ve tried this “fix” on a couple of our own devices and so far it doesn’t seem to make much of a difference. That said, and this is in no way scientific, we tend to get pretty much the advertised battery life on our iPhone 4S units. So, maybe it’s actually a hardware problem on some units and not software after all? Or, perhaps it’s a carrier issue as our iPhone 4S units are all using Verizon and not AT&T?

Whatever the issue, Apple is usually pretty fast to issue a fix for these problems so expect to see one sooner rather than later. In the meantime, let us know if you try this “fix” and what your results are, if any.
