This is a great guide; thank you ifixit! If you’re just removing the battery, there’s no need to remove the display; just be careful with the cables. Use heat right from the beginning. I used a hair dryer or heat gun. Heat the body of the phone under the battery for 2 -3 minutes. Then carefully and steadily pull back on the tab. Apply consistent even force. The battery will pop out to the left and the tab that you pulled on should stay with the phone for next time. Good luck!
