Hello, i am using hp stream 13 with about 9 hours of battery life when i read pdf files. I want this non removable battery to remain in good condition as long as possible. So in that regard, which one would be better for health of my battery: 1) always when possible keep computer plugged in. Since this is a very cheap laptop i doubt it has any special battery options, which means it will probably do what dumb laptops do, charge battery to 100%, let it drop to 99.99999%, charge it to 100%, over and over again. 2) unplug computer when battery is 100% and use its battery power. This means the battery will have quite a few full charge/discharge cycles, going from 5% to 100% and back to 5%. I do not use my computer everyday for a whole year. For instance there comes a week when i use it 5 hours everyday but then there comes a week when i dont use it at all. I make sure the battery stays above 5% at all times.
