Battery broken, how can I open my Huawei Mate 10?

I charged my cell phone overnight, for 6 hours, and I just got 64%.

Have you ever tried a different cable?

It is often because of it.

I've also had dust in the charging socket before and this had the same effect

I have to try it

I wouldn't open the cell phone myself, take it to a repair service…

But if you used such a cheap cable from Tedi I would get another one
