iPhone 5 Battery
iPhone 5s Battery
I skipped steps 11-16 and that worked pretty well from me. On another commenter's advice, I simply used some packaging tape to tape onto the top of the screen, over the top of the phone, and onto the back of the phone to hold the display at a right angle to the rest of the device. Saved me all the trouble/risk of disconnecting the display, but if you use this method you should be VERY careful not to hit the display while removing the battery.
