Heating the back to replace battery not working.
Got the replacement battery and full tool kit from iFixit. I don’t have a microwave, so checked on the repair guides and followed heating the gel pack in a 350F oven. Let it heat up for 10 minutes and layed it along the back edge of the S8 phone. Used the suction cup and spurge tool.
Wouldn’t budge. reheated and tried again. Nothing. So, I used my heat gun (eco heat, (similar to a Master heat gun) set at low temp (400 F). First time very carefully and still no separation of the glue. Another try with the heat gun and still couldn’t get the S8 apart. Let it cool and checked it.
The heat had de-laminated the screen in the bottom quarter near where I had heated it.
So, I’m disappointed. My Galaxy S8 still has a weak battery and now the screen is partially de-laminated to boot.
At this point I’m not sure if I want to try again and don’t really want to buy a microwave just for this.
Also, to note, I’m a retired audio and lighting engineer and have built computers, made my own custom cabling, repaired moving lights and audio gear for 40 years, but this is the first time with a glue sealed phone.

Just to add some more info, I tried again and after a few heat applications the back adhesive began to soften. excitedly I started prying up the cover and about half way around cracked the glass. Oh well. This is how we learn. Forgot to add additional heat since I didn’t realise how brittle the back is. So just ordered a replacement back and fingerprint adhesive.
Now to continue with the battery!
The damage on the screen is liveable and the delamination may have started when I dropped the S8 a couple months ago on the corner.
Will update as it goes on (maybe some “broken glass” pics, I’ve always liked that album anyway).
