Optimizing your battery life
Actually, your notebook battery life needs your computer’s configuration and the way you’re using your computer. Check some of following settings and steps that you can use in order to get the most from your computer’s battery.
Check Battery preferences
You should consider, the Battery pane in System Preferences has special settings to improve the battery life on your Mac notebook. To show Battery settings, choose Apple menu > System Preferences, click Battery or Energy Saver, then select the Battery tab.
In order to have the maximum battery lifetime, it’s better to follow these settings:
- Turn on “Slightly dim the display while on battery power”. This setting helps your Mac adjust the display brightness to 75% when you unplug the computer from power.
- Turning off “Enable Power Nap while on battery power”. This setting stops your Mac from checking for mail or other iCloud updates during sleep which improves standby time.
- Turning on “Optimize video streaming while on battery”. This setting lets high-dynamic-range (HDR) video play in standard dynamic range (SDR) while on battery power, which uses less energy.
- Turning on “Automatic graphics switching”. This setting lets MacBook Pro models with multiple graphics processors automatically switch between them to maximize battery life.
Set display brightness
Normally, your display adjusts the brightness to conserve power automatically. When you turn off automatic brightness, you should turn it back on later to preserve battery life. In order to set the brightness automatically, you should select Apple menu > System Preferences, click Displays, then turn on” Automatically adjust brightness”. Here you can learn how to adjust your brightness manually.
Check battery health
You should check the health of your battery in Battery preferences or the Battery status menu:
- In macOS Big Sur, select Apple menu > System Preferences, click Battery, select Battery in the sidebar, then click Battery Health.
- In macOS Catalina or earlier, hold the Option key and click the battery icon in the menu bar to reveal the battery status menu.
You’ll have one of the below status displays:
- Normal: The battery is functioning normally.
- Service Recommended: The battery’s ability to hold charge is less than when it was new or it isn’t functioning normally. You can continue safely to use your Mac but don’t forget to take it to an Apple Store or Apple-authorized service provider to get your battery evaluated.
To get service on your battery, contact Apple.
In earlier versions of macOS, the battery status might display Replace Soon, Replace Now, or Service Battery if your battery holds less of a charge than when it was new or needs to be serviced. If the battery’s lowered charging capacity is affecting your experience, get your battery evaluated at an Apple Store or Apple-authorized service provider.
While some third-party apps report on battery health conditions, the data reported by these apps may be inaccurate and isn’t a conclusive indication of actual diminished system run time. It’s best to rely on the information reported in the battery health menu, described above.
Analyze battery issues
Let’s see, how to check your hardware, identify apps or features contributing to high energy use, and resolve charging issues.
As a matter of fact, a great place to start when troubleshooting battery issues is the built-in diagnostics that are available on your Mac notebook. Learn how to use Apple Diagnostics on your Mac.
When you don’t find any issues with Apple Diagnostics, so read on for more information about troubleshooting your battery.
Check the battery status menu
The battery status menu always shows you how much charge your battery has and whether it’s charging at present. You can find this menu at the right side of the menu bar:
The battery status menu also shows you if your display or any apps are using significant energy. But notice to close any apps that are mentioned to save battery power.
If you use optimized battery charging in macOS Big Sur, you’ll see more information when your Mac is connected to power, like whether charging is paused or when your battery will be fully charged. If charging is paused and you need to have your Mac fully charged sooner, press Charge to Full Now.
Resolve charging issues
To get help with other issues like, when your Mac won’t recognize a power adapter or charge to 100%.
In case your Mac isn’t charging
Check the correct wattage AC adapter for your computer. A power adapter rated for a lower wattage than is necessary for the system might not reliably charge the computer. If you’re not sure which power adapter to choose for your computer, learn how to find the right power adapter and cord for your Mac notebook.
For more help, learn what to do if your USB-C power adapter isn’t charging your Mac notebook. If issues persist, shut down your Mac, close the display for 30 seconds, then try to charge again. Or if you have an Intel-based Mac, reset the SMC.
If your Mac won’t charge to 100%
If you use optimized battery charging in macOS Big Sur or use macOS Catalina or earlier, rarely the battery might not show a full charge (100%) in macOS, even after the power adapter has been connected for a prolonged period of time. This behavior is normal and helps prolong the overall life of the battery.
Service the battery in your Mac notebook
You should mention that, MacBook, MacBook Air, and MacBook Pro computers with built-in batteries it’s good to have their batteries replaced by an Apple Authorized Service Provider. Trying to change a built-in battery yourself could destroy your equipment, and such damage is not supported by warranty.
Some older Mac notebooks have detachable batteries that you can easily replace on you own. Contact an Apple Authorized Service Provider for assistance servicing a removable battery.
Battery warranty information
Your Apple One Year Limited Warranty contains replacement coverage for a defective battery. when you bought an AppleCare Protection Plan for your Mac notebook, Apple will replace the notebook battery at no charge if it retains less than 80 percent of its original capacity. If you don’t have coverage, you can have the battery replaced for a fee.
Understanding batteries in Mac notebooks
MacBook, MacBook Air, and MacBook Pro computers come with lithium polymer batteries to prepare maximum battery life in a compact space. In order to understand battery technology and battery life, it’s better to know common battery terminology:
- Cycle count: Batteries are expected to function for a certain number of cycles. This number represents the sum of total and partial discharge cycles throughout the life of the battery. You can see the cycle count limit for your computer by reviewing Determine battery cycle count for Mac notebooks.
- Full charge capacity: Measured in mAH (milliampere-hours), this refers to the amount of power the battery is capable of containing, less the energy required to shut down the device. This number lowers as the battery becomes depleted with usage and age.
- Remaining charge capacity: This number represents the current amount of power left in the battery as measured in mAh (milliampere-hours). Using the computer when not connected to AC power will cause this number to lower as power is depleted from the battery.
- Defective: Batteries are considered defective when they stop working due to a defect in materials or workmanship, or due to a manufacturing defect. Defective batteries are covered under Apple’s one-year limited warranty and extended-service contracts.
- Load: The amount of activity being performed by a task or tasks. Certain power-intensive processes place a heavier load on the battery and result in a much-reduced runtime per charge.
