So here's one for ya.
Battery life seems to be an important topic, so let me give you the best battery tip yet.
I used to research and read about how to extend my battery life on my Evo 3D. So many people will recommend the following:
Turning off different features on the phone such as wifi or 4g
Killing or turning off background tasks
Killing apps or apps that run in the background
Adjusting screen brightness to a dim setting
Using a battery management app such as juice defender
Disabling the gps
Disabling the auto sync
Disabling the background data
Here is the best battery tip yet based on my trial and error and real life experience. Simply purchase additional oem battery packs plus a wall charger for way cheap on eBay. For example, I got a 3 pack of batteries and a wall charger for my Evo 3D for only $15.
Having additional battery packs is a game changer. I don't ever worry or think about whether I have enough battery charge, nor do I ever have a need to plug in my phone to a charger. I keep a spare charged battery in my pocket just in case I need to swap batteries, and one other charged battery in my computer bag.
Dude, it totally makes sense!
I now enjoy everything my phone was designed to do at the speed it was designed to do it in, at the screen brightness that impressed me in the first place.
Fast processing speed, super screen brightness, fast internet connection, and more battery power than I need? Heck yeah! It's totally worth $15. Just sayin.
