How much does this matter to you when shopping for a new cell phone? Would it be the deciding factor in your purchase?
For me, the two biggest features are: 1. Camera quality 2. Switchable batteries I take shit tons of photos.
I got a portable battery charger. When I'm out and about and my phone battery is low, I just plug in and it charges the phone in 15 minutes. It holds like 8 full charges, and I an use the phone while plugged into the charger. The charger is like 3"x5"x2" (2" thick). It wasn't that expensive - $39.
FWIW; my S4 camera is shit compared to my new Iphone 6. And the HTC ONE (first edition) was shit compared to the S4, unless it was darker out. I appreciate a good quality camera on the phone, but dont care about removing the batteries because im always around a charger.
I have to take pictures for work. I used to lug around a Rebel. The photos my S5 takes aren't as good but are good enough that I don't bother bringing the camera anymore. I'm getting an S6 which will hopefully be even better.
