It is said that the M1 and M2-equipped MacBooks can last an average of 9 to 13 hours on a single charge, but pre-2020 Macs can only last 5 to 7 hours. However, these figures are only estimates, as different people’s work habits and personal The habits and applications you use on your Mac can affect battery life.
I have been using MacBook for many years. When the computer is closed and in hibernation, it will lose power quickly . For example, after one night, the remaining power is only about 50%. Or, the computer is out of power after not being used for many days during the holidays. I suddenly want to use it, but it can’t be turned on and I have to find a charger. I have tried online methods to reset the Mac’s SMC or restart the computer, which can solve the problem temporarily, but it has been delayed until now. After losing 50% of the power overnight , I decided to solve it completely.
If you are not running any large CPU-intensive applications and are running the latest macOS version, and the brightness is usually 50-60%, but your MacBook Pro is still draining power quickly, you can refer to the following method to solve it .
Why does my MacBook battery drain so quickly?
The user’s operating habits will directly affect the battery consumption. For example, adjusting the screen brightness, using high-CPU power applications such as playing games or transferring data, and turning on various function switches (such as Bluetooth, Wi-Fi, background applications, etc.) will make the battery drain faster.
If you set the laptop to airplane mode, adjust the screen brightness to the lowest, turn off automatic brightness adjustment, Wi-Fi, Bluetooth and other functions, or even delete all applications, the standby time will be the longest, close to the officially advertised standby time.
But in reality this phenomenon does not exist, so unless the battery is in maintenance status or has an automatic shutdown problem, the battery is normal.
Pinpoint battery problems
In order to find a suitable solution, you first need to accurately diagnose the battery problem. The following methods can help you make a preliminary judgment:
Check battery health
In the “About this device” information, you can view the battery cycle count and battery health status. The cycle count refers to the number of times the battery is fully charged and discharged. Generally speaking, the more cycles, the more obvious the battery performance declines.
Observe the charging speed
If charging is noticeably slower, there may be a problem with the charger or battery connection.
Test battery capacity
You can use third-party software to perform a battery capacity test to evaluate whether the actual capacity of the battery meets expectations.
Observe system logs
Check the system log for any battery-related error messages, such as charging failure, abnormal battery temperature, etc.
