I have come to grips with the fact that with all the phone can do you have to sacrifice battery life. On a normal day i an have access to a electric so i bring my charger with me to charge when needed. i use a power app and keep everything off that i am not using but, that is not enough. on ebay there are plenty of battery charger/multiple batteries so you just swap out the battery. the majority of the posts have 2 or 3 batteries but, they are rated at 1500mAh. the one that came with my phone is 1650. will the 1500's work? is it even worth getting them or, should i look for 1650's? just want to make sure i am getting the right and best batteries. i know there are much bigger batteries that come with a bigger battery cover but, i would rather swap out batteries than have a bigger phone.
