I have a 13-inch 2016 MacBook pro whose battery life has recently cratered -- I'm talking 2-3 hours to fully discharge. The charge capacity is still at 90% of design capacity after 163 cycles (so ~4000 mAh), but at this rate of discharge the cycles are starting to rack up....
According to coconutBattery, the discharge rate is frequently above 20 Watts while I'm doing little except browsing the web or writing email (consistent with the discharge times I'm seeing). My initial guesses for the culprit were Chrome and/or Dropbox but experimentation disproved those theories. (Have nevertheless finally switched to Opera.) Neither the Activity Monitor nor ps indicate any process using significant energy or CPU.
Is this more likely to be a battery defect, or some sort of rogue process? Any advice for how to go about diagnosing the problem?
