Hi guys, I just got my SP3 for a few days, and I am not sure what's the best way to protect battery lifetime when I charge. At first I thought it can be charged like a laptop/desktop, but then I realised it uses Li-Ion battery, just like in smartphones. So I got confused... (1) can I use SP3 while the charger is plugged in all the time? (even when it's already 100%) I don't seem to find any mechanism that stops battery from charging when it reaches 100%, like in most laptops (I don't see "plugged in, not charging", it's always charging) (2) do I have to charge it above 80%, then use/drain it below 20%, then charge again in such cycles, like in smartphone/tablets? Coz this would really be a pain in the ***. Thanks for helping in advance!
