I use a lot of phones on a regular basis, probably more than the average user. Or perhaps even more than the non average user.
One thing I’m always looking at is battery life. While I don’t formally test battery length, my standard test is simple. Can the phone get me through my toughest day of use without dying or make it through two casual days of use. That’s a typical usage scenario for me. Often, the answer is no and that’s why I’ll often use many 3G devices with EDGE turned on and not 3G.
I think there’s two reasons for this. First 3G radios inherently use more power to a greater degree. Second, the added functionality of 3G leads to increases in usage models and the battery drains faster. Let’s face it, when you browse the web and it’s a good experience, you tend to do it more. Add in things such as streaming audio or video and driving the screen even more and you’re going to take a hit on overall battery life over the course of the day.
Eventually battery life will get better as both chipsets and software improve to handle increased usage models. As for today, Most of the time I have found no problem getting through a day on the road but find I mostly have to recharge most devices at night. As for a really heavy voice and data day? There’s only a couple of devices I’ve found that can handle that load with 3G turned on. So, what’s your 3G experience?
