If you're gonna re-use the battery I wouldn't use heat, it damages the cells inside of the battery. Just pry with a spudger and have

joey Van beek - Réponse

I'm sorry I don't agree with a spudger without adequate heat the battery would bend to be removed. The adhesive is very resistant and the heat must be dosed appropriately for the situation so as not to damage the battery and the other components

Smilzo -

In another vid, to remove the battery “without" heat, the person used “rubbing alcohol” said it consumes the adhesive making it very easy to remove, placing it with a syringe like tip, along both the left and right sides, when the phone is in the normal upright position. And because rubbing alcohol evaporates, it's not harmful to the phone. Then a spudger can be used without brute force. That was a vid for the A205. (2019)
