Inconsistent charging of 2017 MBP 13" (A1708) I own a 2017 MBP 13&quot; (A1708) with the battery replaced about 6 weeks ago. Everything went nicely until this week, when it started charging inconsistently and coconutBattery shows 5-10W of charging. I plug the charger and it says &quot;battery doesn't charge&quot;. Sometimes reconnecting the charger helps, sometimes not; the same is true about waiting some time. I've reset SMC couple time but it usually doesn't help. I’ve attached of screenshot showing coconutBattery output.
Also I’ve ordered a new charger and cable.
Sometimes, your mac will do this to preserve the battery. It learns from your charging habits and will wait to charge past 80% until you need it. for example, if you go to work every day (ok, maybe not right now during covid) at 8 o clock, and have your mac charge the entire night, it will charge to 80 during the night, then at around 7 o clock, finish charging, and by 8, it should be at close to 100%.
