Hello, My MBP has a new Simplo battery ( Manfacture Date 2020-05-15 ) with only 3 charge cycles. I restored my MBP with a Time Machine backup last week, now my MBP is saying that my battery needs a service. I let my MBP run down the battery until the MBP turned off, left overnight then rest the SMC, but it is still saying the same. I have Installed macOS High Sierra. CoconutBattery Says: Design Capacity: 6600 mAh ( 75.8%)Full Charge Capacity: 5000 mAh (100%)Current Charge: 4998mAhBattery Temp: 21.6 CelsiusAge 84 DaysPower Adapter: 85 Watts

Any help? Thank you Antony
