If the battery is knackered how to repair?

Currently a Fitbit Charge 4 for a person I know, currently has a potential battery knackered issue. As for certain functions (especially re-setup) if needing to clear paring due to Bluetooth pairing crypto key corruption.

Its battery must not go below 70% in order to re-setup, also experiencing intermittent connection issues. I’m wondering if its battery is knackered and/or needs changing, so thus if it’s changeable and how to do it for this device.

Can anyone help me with this please?

@john95761 this "battery must not go below 70%" sounds like a battery issue. This is a beast to work on. There are no good guides for this yet so you walk a bit in uncharted territory. Use something like this video Once you have the display removed, you will need to remove the circuit board to get to the battery. All those parts are visible in this video

Batteries are available at places like this Fitbit Charge 3 and 4 Battery.

While you work on your Fitbit, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.

Repair is War on Entropy!

I’m in the United Kingdom not the US, but still need access to battery parts.

Though the idea of creating a guide is a good one, once have figured out how it’s done. Should suitable photos be taken, notes will also be needed in order to create a guide.

@john95761 something like this would work. You know that you are looking for a LSS271620SF battery. Of course, do an online search and see what works better for your geographic region.

iFixit mods and admins are always willing to assist when it comes to the guide creation :-)
