Double your MacBook battery life (macOS 2 or later)

The m1 MacBook has good performance, but it generates less heat and, above all, the battery life is much longer than before.. When you go to a cafe, you don't have to carry a power cable and you don't have to look for a place with a power outlet.

Today, I came to the cafe without fully charging the MacBook. There should be 5 hours. I use Xcode while listening to music on YouTube, so I need to use some battery. Turn off Google Drive sync.

Normally, I see that the battery indicator of the m1 MacBook has 20 to 8 hours left, but today after using it for a while, I have 2 hours left.



Low Power Mode Added to M1 MacBook's macOS 12 Monterey

Suddenly, when I upgraded to macOS 12 Monterrey, I remembered the low power mode in iOS in the battery settings.

Low power option turned on.



Turning on low power mode doubles the remaining battery life

The battery life of iStatMenu has been increased from 2 hours to 4 hours.

The remaining battery time is active or free Stats can also be seen as

However, after using it for a long time, it is extended to 4 hours instead of 5 hours! not double

The remaining battery time of iStatMenu is not accurate. It will depend on which app you are using. However, I didn't feel any slowness in using it.



Low Power Mode on M1 MacBook

iOS Low Power Mode limits background usage, but what does Mac Monterrey do?

I found that it slows down the CPU and GPU speed and lowers the monitor brightness.


When the M1 MacBook Air is in low power mode, the performance is comparable to that of the 2020 13-inch Intel MacBook Pro.this comes out

The battery of the M1 MacBook Air lasts a long time, but it's also a great value for money.


This applies not only to the M1, but also to the Intel Mac. commentIt seems to work well on the 2019 MacBook Pro.

It's Intel 2019 MBP, and after the update, the battery saver mode works well.
There is no feeling of slowness in use, and you can feel that the battery life is definitely increased.




Will the battery last 100 to 40 hours if charged to 16%?

Then, if 100% charge is 20~8 hours, is it 40~16 hours if low power is turned on?

After charging to 100%, I removed the battery and turned on low power.


time does not increase I do not know why.
