I got 4-5 hours from the buds - which is about par for this price.
From FreeBuds 3, I got around four.
FB 3i are less than three hours, which is poor.
Cannot remember the Samsun Galaxy Buds+ - I assume they were grand though.
The Buds+ actually blew a lot of the competition out of the water as we managed to get 9.5 hours out of them on a single charge! Not sure why other manufacturers can't offer all day battery like this to their earbuds as well!
We're really enjoying our time with them so far too, shame there's no ANC though and the battery life could do with a boost too though.
