I had an Oukitel that I ran for almost 4 weeks. Had to charge it for a trip off grid. Talk about chunky!

Might buy another model, but had to drop Verizon to get it working and T-Mobile took a week to figure out how to activate it. PITA, but it was solid once working. Great BT speaker, couldn't kill the battery, everything worked great. Carrying the thing was a pain, even with a pack. Not sure I want all that mass again.

If you want a phone you can beat a man to death with, Oukitel it is!
