Anyone use the likes of the Hyperion or Anker extended batteries
with their Freedompop Galaxy S3s? The stock battery goes from fully charged to dead in about 10-11 hours even if I don't touch the phone. I have disabled a bunch of apps I don't use, the brightness is set to minimum, etc. but it still isn't enough for my needs. Just curious if anyone has used the extended batteries (preferrably in the 4200-4400mAh range, since the 7000+ batteries can decrease your signal strength) and if they have noticed any adverse effects with either the battery or larger back that they come with?
