Picked up the Evo 3D, read the reviews, all great except for battery life. True, battery life is nowhere near on par with the iPhone, something HTC really needs to work on. That being said, I didn’t want to require charging my phone after 5 hours, as a few reviews appeared to allude. Unfortunately, this appears to be due to the device shipping with a bunch of settings enabled that, well, shouldn’t be. So, here’s what you do:
- Turn off GPS
- Turn off WiFi
- Turn off 4G
Really, how often do you use those? Sure, when you’re at home or the office, WiFi is fine. But GPS? Seriously? Unless you need directions to everywhere you go, or you need apps to have pinpoint accuracy of your location, you don’t need those services running.
And 4G, regardless of carrier, is a joke. Yeah, it’s fast, but it really does kill your battery. Maybe in a year or two we’ll have the chipsets that are power efficient enough to enable keeping it on all the time. Right now? No, it’s just like laptops with NiCad batteries. Remember that? If you do, you’ll commiserate. If you don’t, be happy you have Lithium Ion in your devices these days. 3G is perfectly fine for almost anything you’ll do on your phone. Hey, it’s still faster than a lowball DSL connection. Cool, eh?
With the above settings, my Evo 3D runs fine for a whole day, even with average app usage. “Average” for me is a round or two of Angry Birds, a few Foursquare checkins, checking my email a number of times, taking a photo or two, and keeping Skype & Facebook running in the background.
I hope this helps you!
