Battery metering accuracy issues on X280 @OC0.9.8

Hello experts,

After the macOS deployed on the computer, I am confused by the battery accuracy issue. The battery shows it has 100% for 2~3 hours and it suddenly drops to 6% in seconds.

I don't understand if it's the defect of SMCBatteryManager or YogaSMC patch. Any suggestions or corrections are welcome and I appreciate any help on this issue. Thanks a lot!
