I also googled that not charging problem and found that so many other issues exists, so my case is not something special. For now i'm thinking to grab nano s plus which has no battery at all and I hope to get rid this issue in future.
After buying such a defective device, do you still have confidence in the company that manufactured it? For most people, this would be a sign to look in another direction, but as far as I can see, you are good with electronics, so maybe you need new challenges?
I blame Ledger because they can't make proper reliable battery contact, and why they wouldn't just hire normal engineers. So i only disappointed of quality of Ledger X not all Ledger product lineup, therefore i might buy Nano S Plus. BTW i got Trezor Model T, i bought both devices to compare them. Trezor lacks some coins i need in Ledger, so i need to use them both.
