  • Use a nylon spudger to pry the battery from the phone.
  • The battery may bend a little during removal which is normal. However, make sure the battery doesn’t bend too much as that can make it dangerous. If it looks like it’s folding, try prying it from a different angle.
  • Avoid using metal tools to pry the battery out of the case as it can pierce the battery.
  • Contents of the battery are extremely polluting to the environment. Do not throw it away in the recycling. Instead, try finding out what your local community does to dispose of batteries.
  • After removing the battery, the adhesive will not have as strong of a hold on the new battery. This should not be an issue. However, if the adhesive strength is negligible, you can consider buying adhesive and applying it before inserting the new battery.

This is much more difficult than it is depicted; while I’m not an electrician, I’ve acquired skills as a sailor over the past 8 years. Damage to the device is nearly guaranteed. I would NOT recommend trying this operation.

Have you actually tried? With the proper tools and care it doesn’t seem that difficult. But then I was a computer tech and repaired laptops. For anyone inexperienced or lacking patience, you’re probably right.

It’s actually pretty easy. I’m guessing your main concern is ESD… You can avoid electrostatic discharge by using the proper tooling and ESD mats.

The instructions were good. Please note the cable under the yellow tape is very thin and not really visible against the backdrop. Mine tore and made camera not function correctly.

Also note, I couldn’t remove the last screw off the motherboard. It was too tightly inserted and was stripping by attempts. I turned my phone face down with gorilla glass against a heating pad on a low setting for just a few minutes to warm the adhesive on the battery. Keep the top section with the motherboard off the heating pad. This was the easiest thing to remove. Use a plastic spatula not a metallic one.
