[QUOTE=cjtownman;1103992]What brand/model do you have? I happen to have a lot of inside knowledge on this one.
If you have an iPhone, my favorite thing is the Mophie Juicebox. It is a case for the phone with a battery built in that can fully recharge the iPhone. I have a regular case for mine and the Mophie too. Looks like a normal case, flip a tiny switch on the side, you are good to go.
HTC devices, you can buy larger/replacement batteries off of Amazon.com for pennies on the dollar my corp charges for them. Are they be best quality? Probably not, but they are sufficient.
Other Android devices, there is a great app called JuiceDefender that can make a great difference. It will turn off/reduce sync recurrences to really cut down on the smart phone features which really suck up power. The free version is horrible but the pro version is fantastic.
With most brands, there is a trick or two. I have access to a lot of the tricks, let me know.[/QUOTE]
I like the sound of the Mophie Juicebox thanks for the info on that:happy: I am off to go find one now!
