I am using an E52 and I use it often as a modem on my laptop.

The point is, that every time I connect my mobile to the laptop, the battery starts to recharge. Is there any option where I could tell my mobile that it is only supposed to recharge below a certain level? That would save me the money of buying a new battery within the next twelve month
I know that laptops (like lenovos) have this option so I was asking myself if this is possible on my mobile? Otherwise I would suggest such an option in a future release!
