Did you get any official response from Ledger about what is causing such fast discharging of battery?
Unfortunately, I did not get any kind of information about that. The support only declared that both devices were faulty after seeing my recordings of the wallets and a watch alongside them.
How many times you guys can use the Nano X before the battery needs to be recharged? Is it that bad?
If you don't keep your device turned on needlessly (meaning you turn it on after preparing your transaction) then it should last for quite a few transactions. I can't give you the exact number since both of my devices were faulty (the first one seemed to work fine at the beginning).
I'm thinking of getting one because I might travel a lot in the next few months and don't want to carry my Nano S around.
If also you don't want to carry around your laptop then it's a great choice. Their mobile app is fairly good.
