Life isn’t fair sometimes. This thing even went though the courts and somehow the onus is still on the buyer to prove something was wrong, when it is clearly a design issue.

I guess there is enough noise around the issue these days to get the dealer to properly fix it, but back in 2019/2020, no one believed you had a tiny power drain, and it would have been very costly to prove it (including time), and then who knows if you could litigate successfully.

Hell, if the power drain was only happening while not able to connect to 3G, the issue would be so location specific/sporadic enough, that good luck proving it even to yourself.
