My Charge 5 (2yrs [sic] old) was working fine until I ran this update. Now I have to recharge it at least twice a day. Fully charged last night wore it for sleeping & flat when I awoke this morning. Have tried resetting ... as per the advice on here. Has made no difference. Really disappointed as I love my Charge 5. I see a direct correlation between this battery issue and the update even though Fitbit reckon that's not the case.
There are similar recollections and accusations against the firmware update on the support thread, which is 21 pages long as of this writing.
