9. If your battery dies, you can replace it

LG G3 battery

This is one of those specs that sometimes gets glossed over for any number of reasons. But for those who need it, it's damned important. The LG G3 has a removable battery. That is, you can take it out and replace it with a fresh one if you run out of juice.

Does that imply that battery life isn't great on the G3? To the contrary, Alex says. "Even on our pre-production Korean G3 on UK networks, which it hasn't been optimized for, we're seeing a little over 15 hours of relatively intense usage per charge. That's on par with what we're getting from the HTC One M8."

So it's a nice feature to have if you need it.
