Unfortunately both bottom and upper strips had been broken after pulling a little. After that, removing the battery was a nightmare. I used pry tools to lift the battery out beginning from the bottom side. I heated bottom of the battery via heated air blower as lifted, used dental floss etc. Battery is crashed while lifting via pry tools, its tip had been burned, a strong odor reveled. After a though fight, removed the battery. I probably damaged wireless charging coil, its black protective shield was peeled place to place. I hadn't removed out the taptic engine before replacing battery, so I worried about it to be damaged because I applied some force to battery from bottom side initially. After replacement, everything seems working flawless; battery, home button, touch operations, NFC etc. I haven't used wireless charge before and not tried yet after replacement operation; I hope it also works and everything continues to work flawless.

Unfortunately both bottom and upper strips had been broken after pulling a little. Maybe I have pulled in a wrong way or maybe they had been more brittle as the time passes.
