Just replaced battery on my iPhone 5. I skipped the step 9 thru 12 and just gently held the top display while removing the battery which just popped out after very minor prying out. I guess the glue was not so sticky. Put the new battery in place , connect the connector, 2 screws, pop the lid back in the place, 2 more screw next to charging connector and 10 min later, the surgery is done and new battery which had 2014 year manufacturing date on it is in. Worth the extra $$$. Ebay/amazon sells these batteries for around $10, but no manufacturing date on them??? I did spend extra money but I think its worth it. You know what you getting here.
