Question for those with a spare battery for HTC Evo

[mantczak]

I have been wanting an extra battery for quite a while and now that the Netflix app is out I will really need it.
I prefer to get a regular battery since I do not want the extra bulk. If the battery is charged up and not inside the phone will it gradually lose the charge or does it stay fully charged?
Thanks

Hey Mant,

I have 2 1700mA batteries that I exchange through my Evo. I charge them in a plug-in charger and they keep 100% charge for at least weeks at a time. Hope that helps. I say go for it.
