To make it short, most of those are used batteries, the rare pristine ones come from loooong sheltering, and that make them almost dead. This is a dead end device now. Even my N5, I bought a polarcell new one, last hardly a day with doing almost nothing, long sheltered battery there also.

I share mine, even if I used telegram only couple times.
Never had more spam than before sharing it with them.
