Galaxy S8 - Where to buy replacement battery from

OpenToSuggestions · 11 Jun 2020 at 14:12

Hey all.
My S8 is over 3 years old now and the battery below 20% charge dies in a matter of minutes.
I've already replaced the back of the phone before so replacing the battery can't be much harder.

Question is where can I buy a good quality battery from? Ebay prices suggest cheap knockoffs or used ones.

Ordered one from Ifixit a day or so ago.
I will post back with the results

Battery from Ifixit fitted. I managed to break the back of the phone, doh! £7.50 for a replacement from Ebay.

The phone seems to be taking AGES to charge.

Do Li Ion batteries take a long time to charge the first time around?
Is there a setting in the phone where I tell it that it has a new battery?

Was 55% when I added it. I let it die then charged to 100%. Seems to be holding charge just fine though.

Why did you do it that way?

I had family commitments I couldn't get away from and didn't want to mess it around with partial charging.
It is working just fine now.
I am waiting on the replacement glass back to arrive from Ebay

Hi.. Do you still have the phone? How is the battery.. I'm kinda in the same boat..o don't really need a new phone but battery live is really bad

I changed the battery with the kit from Ifixit

Worked a treat until some fool (me) dropped it and smashed the screen!
One thing to note is getting the rear glass panel off is near impossible without cracking it. I recommend buying a used one with the adhesive pre-applied from Ebay for ~£10.
