Very odd Cpu Throttle On Battery

Perment CPU'' throttling (0.8 ghz according to Intel Power Gadget ) only occurs when on battery below 60%. But thats not all. While its certain when above 60% throttling less, its undoubtfully still present. This trend is carryed on until it reaches 95% where throttling is no more present. Also from 95 to 100*** percent the laptop feels siginificantly faster than its other counter-percentages. Any help is much appreciated. Btw I did also check whether it was thermal throttling turns out it wasnt.

  • According Coconut Battery (Battery health: > 80%)

@danj Thankyou so much . Even though coconut battery reports that the battery health is above 80%. The battery could still be faulty. Even Apple's System Diagnostics couldn't detect the issue.

crwdns2893770:0crwdnd2893770:0crwdne2893770:0

@tigerblue950 - Diagnostic tools have there limits. Sometimes its experience and age is also a large factor. This battery is pushing eight years!

Think of it this way... In Eight years have you seen your dentist? I'm sure you had a filling or two in that window of time.

Things break down and your battery has its limits as its chemistry does break down over time.
