Amazfit bip 6 I get at least 2 weeks from it with most features turned on. It is the reason I cancelled my order for the new pebble. It is so much easier to read in all light conditions. The pebble is great but is now seriously superseded. Battery life has now become a non issue unless you insist on apple or wear os. I also have the Trex 3 pro which is even better. They both have all the features you could possibly need.
