I'm having problem with my just couple weeks old Macbook entry Pro 1.4GHz 2019 model. Battery full charge capacity drops when there is high CPU load or similar high power consumption situation. Like when I run Cinebench r20 and check full charge capacity with CoconutBattery before and during the test is running, I see that full charge capacity drops from about 5200mAh to 4900mAh during test is running. It goes back up soon after test has been completed. Is this normal for this Entry Pro 1.4GHz model, or is my battery faulty? I tested the same thing with 2.4GHz Pro and it did not drop capacity during test. I'd be glad to hear from other Entry Pro 1.4GHz 2019 owners If they have the same problem with their units? Here are simple instructions how to test this. Run machine on battery (charger unplugged of course) 1. Check battery full charge capacity from CoconutBattery before running Cinebench and write it down 2. Then run CineBench 3. Wait until test has ran for couple minutes and about where CPU fan is screaming at full speed while test is still running 4. Run CoconutBattery (while Cinebenench test is still running background) and check what it shows Full Charge Capacity and write it down 5. After Cinebench test has completed close it and check again full charge capacity with CoconutBattery You saw any drop in Full Charge Capacity when Cinebench was running? Did it go like 5200 > 4900 > 5200, or did it stay around the same in all three measurements? Please list your measured values here.
