You may be aware that the new iPhone 3G S has had problems with overheating, as reported on PriceGrabber among other Websites. But other battery-related problems are starting to surface as well.

According to reports on Apple’s Website and other outlets, battery life, which is supposed to be improved on the 3G S, may be drastically worse. 3G S owners are complaining about batteries that run out in less than a day, or are down to 10% or less battery life. Some of their solutions include resetting their phones to their original, pristine state, and draining the battery fully and recharging it fully before using it.

Even if those solutions work, they shouldn’t be necessary. It looks like Apple may have goofed big-time on this. The problem is made even worse by the fact that, unlike most smartphones and cellphones, the battery is sealed and the phone has to be returned to Apple for a replacement.

A few things I do on my 3G (the non-S model, thank goodness) to preserve battery life: I turn off ‘Push’ notification of e-mail. When I first got my iPhone and used it, I couldn’t figure out why the battery drained so quickly. Turning off this functionality was the biggest factor in improving my battery life. Also, I don’t turn on location services unless I need to use the GPS, and I turn off wi-fi unless I intend to use it. Those three simple things have helped the most.

In the meantime, carefully consider a possible purchase of an iPhone 3G S until more is known about the battery overheating and draining issues.

The good news? The iPhone 3G is more affordable than ever.
