All the newer cell phones have "non replaceable" batteries. Of course the makers do this to force you to buy a new phone when the battery dies from continuous recharging. Good for them, but not good for you or the environment. They try to make them impossible for you to fix. This should be illegal! Here's what I learned from doing Wendy's phone, my second phone this year.
The replacement of the battery by professionals could cost more than your used phone is worth. You can do the replacement yourself but it is not as simple as my pictures and YouTube videos would have you believe.
The screws are the easy part but they are hidden by fragile glass and plastic covers. Don't over heat them or bend them too much when you pry them off. Don't toss the phone if you break something. New parts are readily (and cheaply) available on Ali Express where you can get a battery for less than $20 CAD but you'll need to wait a month or so as they come from China and clear customs. I ordered extra pieces ahead of time just in case.
If you bend the battery it could explode or burst into flames so be careful. Mine started getting really hot so I threw it into the kitchen sink just in case. It's still outside on the cement porch just in case.
Don't use the supplied 3M sticky tape to re-install the battery. The battery has no where to go and the tape is just to discourage you from removal. After all, batteries never used to be glued in anyway. Forego the tape and you will have an easier time next time if you have to do this awful job again in a few more years. Email me if you need advice... and good luck!
NOTE: The first phone I took apart a month ago, I broke the screen because I stupidly missed one small screw holding the back on. This caused the screen to bend and crack. Then I had to pay for a new $100 screen from Amazon Canada. I could have got one for less than half that cost from Ali Express but couldn't wait a month or so.
