Apparently some solvent/cleaner was used to clean up the residual glue between steps 3 and 4 pictures. If so, can you share what was used?

Using a metal spudger, push down on the plastic gray square clamps on the underside of the device to dislodge the whole silver backing. Note: the buttons will also come off.

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?
