Understanding batteries in Mac notebooks
MacBook, MacBook Air and MacBook Pro computers come with lithium polymer batteries to provide maximum battery life in a compact space. To understand battery technology and battery life, it's good to know common battery terminology:
Setting up your Mac for the first time
When you set up your Mac for the first time, some activities — like setting up Mail and Photos, downloading your files from iCloud and indexing your files with Spotlight — can use more power than your Mac requires in general use.
If you have a large amount of data to transfer over Wi-Fi, it might take a few days for your Mac to finish its setup process. It's best to keep your computer connected to a power source during this time. Once setup is complete, the battery life will begin to reflect the regular activities you perform on your Mac.
The battery status menu
Your primary resource for viewing battery status is the battery status menu. It shows you how much charge your battery has and whether it's currently charging. This menu is on the right-hand side of the menu bar:
The battery status menu also tells you if your display or any apps are using significant energy. Click Display Brightness if it's listed under Using Significant Energy, and your display dims to 75% brightness. Also consider closing any apps that are listed to save battery power.
To see the health of your battery, hold the Option key and click the battery icon in the menu bar to reveal the battery status menu. You'll see one of the following status indicators:
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 Authorised Service Provider.
Android Battery App
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.
Optimising battery life
Your notebook battery life depends on your computer's configuration and how you're using the computer. Here are some settings and steps you can take to get the most from your MacBook, MacBook Air or MacBook Pro battery.
Check Energy Saver settings
The Energy Saver pane in System Preferences has options to help improve the battery life on your Mac notebook when it's idle. For instance, setting your display to sleep when idle temporarily turns off the backlight and significantly improves the battery life.
Deselecting 'Enable Power Nap while on battery power' can also extend your battery's charge.
On Mac notebook computers introduced in 2016 or later, the display brightness adjusts to 75% when you unplug the computer from power if you have 'Slightly dim the display while on battery power' enabled.
The example above is from macOS Catalina. Some features such as Automatic graphic switching and Power Nap aren't available on all Mac notebooks or versions of macOS.
Adjust keyboard and display brightness
Your Mac notebook's built-in keyboard has settings that can help automatically conserve battery power:
You can use the F5 and F6 keys to manually adjust your keyboard's brightness, setting it as low as possible while still allowing you to see the keys.
Your display's brightness has a major effect on battery life, and allowing your display to automatically adjust can significantly help to conserve power. Choose Apple menu > System Preferences and then select Displays. Enable 'Automatically adjust brightness' to allow your display to dim or brighten based on your surrounding's light levels.
To manually adjust your display's brightness to a comfortable level, use the F1 and F2 keys.
MacBook Pro with Touch Bar
If your Mac has a Touch Bar, you can quickly adjust your display brightness by tapping in the Control Strip on the right-hand side of the Touch Bar. To access the keyboard brightness buttons, tap in the Control Strip:
The Control Strip expands, and you can tap to adjust your display's brightness, and tap to adjust keyboard brightness:
Check graphics settings
MacBook Pro 15-inch and 16-inch notebooks commonly include two graphics processors, or GPUs. You might see them documented as a discrete GPU and an integrated GPU. The discrete GPU generally provides substantial performance at the expense of high power draw. The integrated GPU allows for optimal battery life, but in most cases doesn't have the performance of a discrete GPU.
For optimal battery life on your MacBook Pro, use automatic graphics switching.
Turn off features and technologies that use power
Mac notebooks have a number of integrated technologies that can have a significant effect on battery power.
Troubleshooting batteries
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.
If Apple Diagnostics tells you that your battery requires service and cites reference code PPT004, you should confirm this issue by running Apple Diagnostics over the internet, which uses the latest diagnostic information. To do this, turn off your Mac by choosing Shut Down from the Apple menu . Then press the power button to turn on your Mac. Immediately press and hold Option-D until Apple Diagnostics begins.
If running Apple Diagnostics over the Internet confirms the issue, contact Apple or take your computer to an Apple Authorised Service Provider or Apple Retail Store. They'll tell you which service and support options are available.
If you don't find any issues with Apple Diagnostics, read on for more information about troubleshooting your battery.
My battery runtime is low
My battery isn't chargingMac Os 9 Battery App Macintosh Garden Oregon Trail
Confirm the correct wattage AC adaptor for your computer. A power adaptor rated for a lower wattage than is required for the system might not reliably charge the computer. If you're not sure which power adaptor to use with your computer, learn how to find the right power adaptor and cord for your Mac notebook.
For more help, learn what to do if your USB-C power adaptor isn't charging your Mac notebook. If issues persist, reset the SMC.
My battery won't charge to 100%
Occasionally, the battery might not show a full charge (100%) in macOS, even after the power adaptor has been connected for an extended period of time. The battery might appear to stop charging between 93 per cent and 99 per cent. This behaviour is normal and will help to prolong the overall life of the battery.
My battery isn't recognised
If the battery in your MacBook, MacBook Air or MacBook Pro is fully drained of power, the battery will put itself into a low power state to preserve its ability to charge in the future.
Connect your Mac notebook to AC power and allow it to charge for at least five minutes. If the 'connect to power' screen persists after charging for five minutes, reset the SMC.
The low battery warning doesn't display
If you don't receive a warning when your battery has a low charge, generally reported at or under 15%, it might be because the battery menu bar icon is disabled. Follow these steps to enable the battery status menu item:
Portables using OS X Mavericks v10.9 or later display the low battery warning when the battery has approximately 10 minutes of power remaining. Earlier versions of OS X report it at 15% or less.
Servicing the battery in your Mac notebook
MacBook, MacBook Air and MacBook Pro computers with built-in batteries should only have their batteries replaced by an Apple Authorised Service Provider or Apple Retail Store. Attempting to replace a built-in battery yourself could damage your equipment, and such damage is not covered by warranty.
Most older Mac notebooks have removable batteries that you can replace yourself. Contact an Apple Authorised Service Provider or Apple Retail Store for assistance servicing a removable battery.
Battery warranty information
Your Apple One-Year Limited Warranty includes replacement coverage for a defective battery. If you purchased an AppleCare Protection Plan for your Mac notebook, Apple will replace the notebook battery at no charge if it retains less than 80 per cent of its original capacity. If you don't have cover, you can have the battery replaced for a fee.

Hello harsh79,Thanks for using Apple Support Communities. I understand your battery life is shorter since updating to macOS Mojave. There are a number of possible causes for this, and the best place to start is to check out Activity Monitor. Here's How to use Activity Monitor on your Mac:
Energy
The Energy pane shows overall energy use and the energy used by each app:
More information is available at the bottom of the Energy pane:
As energy use increases, the length of time that a Mac can operate on battery power decreases. If the battery life of your portable Mac is shorter than usual, you can use the Avg Energy Impact column to find apps that have been using the most energy recently. Quit those apps if you don't need them, or contact the developer of the app if you notice that the app's energy use remains high even when the app doesn't appear to be doing anything.
I also recommend that you ensure all software is updated; to do this, open the App Store and click Updates. Then, install any pending updates. I hope this helps to get you started! Mac Os 9 Battery App Macintosh Garden Oregon TrailTake care.
