Replacing my iPhone 6S's 540-cycle battery

Mijn probleem

After 2 years of use, battery was at 540 cycles and capacity was at 63%

Mijn oplossing

Everything went down without a hitch until I had to remove the original battery. I got the first adhesive strip out fine, but tore the second one, so I had to dig around with a credit card until I could sever it.
