  • With a plastic opening tool, disconnect the four connectors on the top of the motherboard.

Where do I buy the parts? I already have your tools.

  • Remove three 3.0 mm Phillips screws on the edges of the motherboard with a Phillips #000 screwdriver.

Add colored markup to indicate location of the 3 screws.

I felt like my #00 driver fit slightly better for these screws, but it probably depends on which toolkit or bit set you have.

  • Grasp the edges of the motherboard and slide it slightly towards the right to remove it from its case.

  • Use a plastic opening tool to pry the battery out of the device.

  • You may need to use a stronger prying force due to the adhesive that secures the battery to the case.

Thanks this was very helpful.

It did help, small correction - Use a T4 instead of T5 screw driver

On my G Watch R the T5 screw driver perfektly fits.

I second the fonejoy link, got it delivered from them very quickly. And I also second what Suyog said regarding the Torx screwdriver, on my own watch I needed a T4, the T5 didn't work, but I had a set so I was okay.

Did you guys retain water resistance after the battery swap?

There is an o-ring type seal connected to the backplate. As long as you are careful when taking the backplate off and also make sure that the channel this fits into when you re-assemble is clean, you should be OK. It’s only about 1mm from the edge of the backplate, so don’t dig too deep with your loosening tool when taking the plate off.

The above instructions worked fine for me as someone who has never done anything like this before … watch is now back to being fully-operational with the latest version of android wear and great battery life. I too used fonejoy .. delivery within 24 hours :) I’d never tried re-connecting this type of PCB connector before and fiddled around for some time before realising that they click into place quite easily. This is probably a 30 minutes job for most of us rather than 5 minutes.
