Dell Inspiron 7537 - Battery Charge Information

Hi,

Does anyone notice any wrong information about battery charge? I use CPUID HW Monitor tool to check temperature and other things.

Last year September, the 1st battery suddenly stopped charging. Then Dell replaced the battery on Oct 10, 2014.
The 2nd battery (current one) starts showing wrong charge information after 2 days.

At 100% charge, the full charge capacity and current capacity should be same. But it was not. Please check the battery section of attached screenshots of CPUID HW Monitor tool at different time.

Also, recently on May 5, the wear level was 10%, then on May 21, the wear level became 11%. Is it possible to wear battery fast? The laptop temperature stays between 40C - 55C.
