It doesn't matter whether your charging method provides 0.2A or 2A (as long as it isn't an extreme such as 210V into a 110V device), what matters is the EEPROM of the device which counts how many charges the battery wants to hold. You charging the battery at 95%, 50% or 3% makes no difference to the battery, however the EEPROM counts even a charge of 5% as a "charge cycle". So, the only real "best practice" is to wait until the device is lower than 10% before you charge it, and if you plug it in to the computer to load more books, you may as well leave it plugged in and deal with the "trickle charge" until it's full, because once it's plugged in, the EEPROM will count the charge.
