    Hi, I recently got a secondhand MacBook 2016. It had a cycle count of 19 and I have been using it for almost two weeks now so the cycle count is now 21. Is it okay to keep my laptop charging whilst I'm using it because I'm scared for the cycle count to go up? Is it also normal if the battery decreases fast, probably 1% every 3 minutes? I'm getting quite worried since I only use it to watch Netflix and nothing else. should I have it checked? The full charge capacity keeps fluctuating also, from 5320-5430. Is that still normal? Thanks!

    Hi there. My advice is do not keep it plugged in all the time or you will end up with battery that has low cycle count and shortened life. Keeping batteries always on charge can significantly shorten their life, they have to be discharged to certain percentage and then charged. Also not good to completely drain your battery, may be once every 6-7 months tops, just for calibration. 1% every 3-4minutes is quite normal I believe.

    so 100% is 300min or 5 hours. thats not much. but ok when CPU is used much. check activity monitor

    when you get with mixed use (web, mail, text and movie) 7-9 hours than u r ok. don't worry about charging while using

    there is free coconut battery app that tells you the remaining capacity of your battery. if less than 80% apple offers free exchange while in warranty period
