Usually you can only fit the same capacity cell.
1) More capacity is larger and rarely fits, except maybe some tablets.
2) Charging system may be for a particular model and capacity of cell.

Technically a battery is multiple cells. That's usually only in laptops. Phones, ereaders and tablets tend to have a single lithium cell now.

A sleep mode saves a lot of power, especially if WiFi & Bluetooth are off.
