But seek to gauge what its 100 % maximum is , and you might err , and it pops suddenly . To avoid this , hardware producer charge Li - ion batteries to a safe level below their theoretical maximum capacity .
Make sure you’re using optimized battery charging for best battery health.
However , as charging starts to go up that degree , devices slow down how much vigour transfer from an AC - to - DC power adapter or a USB battery pack so that it does n’t suddenly “ pop the balloon . ” From 80 to 100 percentage , Apple ’s devices , in particular , take a lot longer than , say , from 20 to 40 percent .
you may use your laptop while plugged in and not worry about whether it ’s at or above 80 percent . Just verify you did n’t change a nonremittal setting : go to > System configurations > Batteryand click the i ( info ) release to the right of Battery Health , and Optimized Battery Charging should be turned on .

The Last 24 hour graphical record shows how the operating organisation ’s analysis of your usage practice reflects charging . On my iPhone , it ’s see I tendnotto get up in the middle of the Nox , so iOS accuse the equipment from near empty at bedtime to 80 per centum until around 3 ante meridiem , and then easy higher after that so it ’s quick when I wake . See : How to chequer iPhone battery wellness .
you could see how your laptop pull off charge on a granular stage over 24 hours ( outlined in redness ) .
You can see how your laptop manages charge on a granular level over 24 hours (outlined in red).
On my laptop , which I keep plugged in intimately all the time , charging keeps it topped up , near 100 percentage . Before Apple added electric battery management tools , I would on a regular basis move out my MacBook Air from power , function it down to almost empty , and recharge it to check that I was n’t accent the bombardment out . Now , I jazz that the arrangement will only lodge as want . It ’s approaching four class erstwhile with 88 pct of its original commission capacity stay .
