I've really wanted to get a bigger battery, not necessarily a bigger phone. I was looking up videos on youtube, and I found a guy who actually bought one of those verizon silicon cases and used that instead of having a new backing for his phone because the battery was so much bigger. Do you guys really find not having to charge your phone for 20-30 hours worth the extra cover and stuff? I'm sure it's not an option for everyone, but why bother with that if you can just charge it sometime in between? Car chargers are cheap, and there should be some time of sleep between 20-30 hours of you using your phone (you know, where you could be charging it). Also, what is the biggest battery you can get without requiring an extra case?
