I am experience something weird with my two MagSage 2 of my MacBook Pro 2015 . It happens with both of them, so I am not sure where the problem is. I am using iStats menu to monitor the battery charge. What I find is that sometimes the "Watts" is around 20 to 40, but never even close to what the charger delivers (85W). Magsafe 2 light is on Amber (correct): Even worst, sometimes it appears as "Not Charging", the Amperage becomes negative and Power Adapter shows 0W instead of 80W.. so it seams like it doesn't recognize the power (and indeed no light is show on magsafe 2): In other moments, it shows as "Draining", the Watts are > 0 but Amperage keeps negative. This is supposed to happen when the magsafe is not plugged at all.
Finally, to add some more information, the battery is beyond its normal cycle count as it's > 1000 (1382).
So...I am completely lost. I don't know if the problem is in both of my MagSafe 2, if in the battery or on my Mac.
Any help would be greatly appreciated.
