Guys if you use your iPhone off course it will drain the battery power, push, beejiveim, anything that runs on backgroup consumes your battery power, everyone agreed right? That's why I don't use winterboard it contribute in draining your battery, I'd rather drain my iPhone's battery using a feature not by draining it by using a theme on winterboard for me, again for me having a nice cool theme is awesome if it won't affect my my battery that much, but in the first place no one even bother looking your phones theme unless your a kid always wants to show everything that you have, again it's just me! But I have this battery charger that you might wanna look in, it's a AA USB charger. It does not have an AC adapter it's USB only. So I use my iPhones AC adapter to charge the AA battery. What's cool about this it has a USB output to charge your iPhone mp3 and any USB gadget, it uses 4pcs AA battery, I used 4pcs 2800mah and it charges my iPhone like 2.5-3 times and what cool about it it's darn cheap and having a 4 AA battery with you and being able to charge your iPhone in one piece of backup gadget is a steal for me, it's nice for me because I always have my canon sx10is digital camera that needs a 4 pcs AA battery and it charge my iPhone too. Pretty helful. Plus if the battery depleted overtime(like 2years) I can just buy another 4pcs 3500mah AA battery and replace my old one and I don't need to buy another iPhone external battery, and did I mention it's just under 15$?
I just wanna share this ok.
