Hello all, I'm an owner of a hacked, customized htc incredible and I just wanted to chime in.
Firstly, congrats on getting an htc incredible! They are severely backordered now, so they are kind of a collectors item!
As for saving battery, there are a few things that you can do. You could buy a larger battery, and that's a fine idea, but if you consider seidio, you may want to be careful with exactly what you buy from them. The battery capacity is generally around 80% of what they state it is, so you may end up getting a battery similar to what you started with if you don't buy a very high capacity one.
Probably the most effective ways to save battery are to:
- Download JuiceDefender, configure it, use it
- Make facebook/twitter/weather/mail/etc synchronize less often, they sync every few hours as opposed to every few minutes on my phone.
- Turn auto-brightness off, and set brightness for what you need. There are brightness apps on the market to make that easy.
Another thing to save battery as what someone else said here is task killers. Task killers are good if you use them correctly, but you don't want to get too excited with them. A good one is 'Advanced Task Killer'. When using these, you want to make sure that their 'kill level' is set to relatively low, because if it goes killing programs all the time, it actually wastes battery instead of saving it. Your phone can handle task killing on its own most of the time, you only need these sorts of programs for occasional clean up.
Also, someone else said to check the battery usage screen, I also think that's a good idea, to see if there's any program that's really wasting battery, or to see if you can adjust your habits to save battery life!
Also, it's nice to have a little panel to turn on/off gps, wifi, and such.. htc sense comes with some of those widgets, but you can also download a program like dazzle to put them all in one place. If you are ever at home, or not traveling around much, you should turn ON wifi, as opposed to 3g wireless, as it can save battery power. 3g wireless can be a battery hog if your wireless signal is low bars. Also, airplane mode is good for if you are watching movies and such, but then again it turns off all wireless, so don't keep it on if you want people to be able to get a hold of you!
It's also possible that you can save battery life by using a different home screen. I'm not sure how true it is, but if you feel like trying something new, I'd suggest Launcher Pro, on the market.
