    • Use a heat gun to heat the adhesive under the battery.

    • Heat the battery for 1 minute then check if it is pliable. If needed, heat in intervals of 10 seconds until the battery can be removed.

    • Over heating the battery can cause the battery to explode. Exercise caution heating the battery.

    • 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.

    Great instructions, however, if you - like me - just want to replace the battery: steps 10-15 are not necessary. After step 9, proceed to 16. Makes it a whole lot easier

    Battery change worked, but now the screen is not working. Any ideas?

    Kelly Eikenberry - Contestar

    I accidentally ripped open the plastic on the grey side of the battery. Is it still okay to use?

    After installing the new battery I got, my display wasn’t coming on. For me, I just didn’t seat the display connector (next to the top most antenna post). Disconnecting it and reseating it did the trick.

    Also, you can run a thin plastic card (like a gift card) behind the battery to gradually work at the adhesive behind it. Just pop up a side with a spudger for clearance and shimmy the card back and forth to gradually remove the adhesive.

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.

Just hit camera to ‘restore default' and camera seems fine. Guess this step was needed after reinstallation. So, only the fingerprint feature was slighted due to torn cable. I've had my phone nearly 3 years and never used that feature.

Deborah Scoggins - Contestar

The time I needed to do the replacement was longer than the 20-25 minute estimate, because I made sure to double-check each step as I went in order to do it right.

While I wouldn’t recommend it, I softened the battery adhesive with a hair dryer, but the downside is that the battery is much more difficult to remove because the adhesive doesn’t soften as much (if at all), increasing the risk of physical/puncture damage to the battery during that step.

Anyway, I enjoyed this project, and the guide was great! It’s nice to be able to repair my own stuff, saving money and electronic waste in the process.

Pretty solid guide, thanks for posting. The hardest two steps are the first, and the 17th. In the first step, I was unable to remove the back cover using the plastic tool alone, and instead carefully used a very thin metal tool to get the process started. At that point, the plastic tools were sufficient to complete removal. In contrast, for step 17, I strictly used the plastic tool as indicated and via slow, steady application of force removed the battery. Heat may have helped but is not strictly necessary, or at least, I did not require it.

All in all a great guide, thanks again.

Yes! “lacking patience” type people probably will damage the phone. This sucks that it’s this hard to remove battery.

matt - Contestar

Great guide and easy to follow! Was able to complete this repair with ease!

what is the best battery to use to replace my old one ….i see alot of knock-off products

Amy Sweet - Contestar

All this is not necessary to change the battery. Only need to go to step 8! DONT pull the mother board and DONT pull the charge board SKIP all that then just disconnect and pull the battery then install the new battery. If you pull the boards you may have problems and waste a lot of time at the least! Other than your instructions that have TOO many unnecessary steps it is well done and good reference to see inside the phone before trying to change the battery so Thanks for that : )
