The phone did not hold the charge well when buying, now just do it even if I don’t use it, what should I do?
Телефон при покупке уже плохо держал зарядку, сейчас вобще садиться даже если не использую, что делать?

I'm sorry to hear that, but since that's a hardware issue, you should get in contact with Sony to get it inspected/repaired.
