This is the second time I have done this job (see above) and this time it took only about 40 minutes. Really good instructions. The only slight disappointment is that the replacement battery I bought from iFixit, and installed in July 2023, lasted less than a year, so I have replaced it this time with one from another supplier. We'll see how it goes. The Huawei Mate 10 Pro is still going strong, and I see no reason to change it.

Very good instructions. The job was quite easy and I did it in about an hour and a quarter. I used a new battery from ifixit, an Ifixit Essential Electronics Toolkit, and a hot-water bottle. The hot-water bottle was one with a flat side (no ridges) to maximise contact with the phone. I kept the phone on the hot-water bottle all the time, so that when I came to remove the battery the glue was already nice and warm, and the battery came out easily.

To remove the back of the phone I inserted the first pick about half way down the side, not in the top of the phone. The back of the phone is a bit more flexible along the side.

After I put the new battery in, I tested it before I fitted the cover. The speaker does not work until you fit the top inside cover.

If you test the phone before you connect the fingerprint reader, THEN connect the fingerprint reader, the fingerprint reader will not work until you restart the phone.

There are some useful comments under each stage of the instructions above.

I left the phone on top of a hot-water bottle all the way through the dismantling, right from the start. That way, the phone was nice and warm and the battery came out fairly easily. There is a slightly wider gap in the housing, just where the spudger is being inserted in the first picture above, which makes the job easy.

The top and bottom inner covers both have tiny flanges which you need to insert into slots in the outside edge of the phone before you drop the rest of the cover into place. If you don't put the flanges in first the covers will not fit properly.

When re-assembling, you can test the phone before putting the covers back on. However, if you test it before you fit the top inner cover (the one in the middle picture above) the speaker will not work.

When re-assembling, you can test the phone before putting the covers back on. If you test it before you connect the fingerprint reader then you need to re-start the phone before the fingerprint reader will work.

This was much easier than I expected! ;-)

I put the phone on a hot-water bottle for about 5 minutes. I put the first pick in the side of the phone, not the top as shown in the next section. Then I kept the phone on the hot water bottle through all the following steps so that the battery glue was nice and warm when it came to that section.

I found it easiest to insert the first pick on the side of the phone, not the top as shown in the pictures. The side is slightly more flexible than the ends because it is longer.
