I'm about to embark on replacing the battery for my fitbit surge. After having it for over 2 years it requires a charge about twice a day which get annoying.
Does removing/replacing the battery require the moderate soldering skill?
I've purchased a replacement band for my fitbit and reattached the bluetooth antenna without glue and the bluetooth works. The first time using the bluetooth after replacing the bad took a bit longer than usual to sync with the GPS satellite but it works now without any out of the ordinary issues.
