Why is my Mac battery draining so fast?
There can be a number of reasons. For example, different browsers consume different amounts of battery power.
Or, swipe up on the touchpad with three fingers to view the windows of open apps, allowing you to quickly switch between programs. This view is called Mission Control, which also has its own. Another awesome method for ensuring your Mac performs at its best is updating the apps on your computer. You can do this one of three ways: The Mac App Store. On your Mac, head to the menu bar. Select the Apple logo on the top left. Select 'App Store.' From the left-side menu, select 'Updates' and update all apps in the queue. The first setting, regarding closing windows when quitting apps, will affect every application on your Mac. However, it won’t automatically make every app open in full-screen mode. You’ll need to set that up individually within each app. Other apps will, however, open in the last state you left them in.
In some cases, a recent upgrade to a new macOS can be the cause and therefore a temporary problem. It either stops doing this in its own time, or a new macOS patch/upgrade is sent through and once downloaded the problem goes away. It is known to happen around the time of new releases and is an issue many Mac owners anticipate.
However, in other cases, the issue is less widespread and more localized. We cover five of the most common problems and fixes for Mac users, in particular MacBook owners who have suffered from a fast draining battery.
5 solutions for Mac battery problems
1. Check and change Battery Settings
In the top menu, where the battery appears, it’s always useful to switch usage to a statistics setting, so that you can clearly see how fast it's draining.
If you click on the battery, it will show which apps are using the most amount of power.
Force Open Apps On Mac
- From here, click on Open Energy Saver Preferences
- Within this you’ve got the option to put the hard disks to sleep and dim the display when a Mac is not connected to power.
2. Switch on Energy Saver
Always useful when trying to conserve battery power on any device, and it could be a lifesaver if you happen to be out without a power cord or plug.
- From the Apple menu;
- Go to System Preferences > Energy Saver
- Now click on the Battery tab
- A slider should be on this screen: Switch Power Nap off, while sliding the scale along to ensure the screen goes dark after a reasonable amount of time when not being used, which should reduce battery drainage.
3. Find out what is using energy
When investigating a fast draining battery, it’s always useful to know what is using energy in the first place. To find out, follow these steps:
How To Make Apps Open Faster On Macbook
- Go to Applications;
- Click on Utilities > Activity Monitor;
- Activity Monitor will show what is taking up CPU and GPU;
- Giving you the ability to close anything that is clearly taking up too much battery power.
4. Identify background apps
Behind the scenes, most Macs can run dozens of apps without us realizing it. Some of these could be running because we forgot about them. Others open during the startup sequence. And others, without us knowing it, could be malware or ransomware, or other viruses, either designed to steal data or steal processing power to mine cryptocurrency or even run remote DDoS attacks.

Now, clearly that sort of thing isn’t ideal and you won’t want apps running that drain power, steal data, or that use your Mac for something you aren't even aware. To solve these potential battery draining problems, we recommend taking the following steps:
- Download CleanMyMac X (for free, here)
- Click on Uninstaller
- It will run a scan of every app on your system: Either click to rest or safely uninstall everything you don't need or aren't aware of.
Also, click the Optimization tab in CleanMyMac. You’ll find the tool called Launch Agents.
It displays tiny background applications otherwise non visible to a user. This very often gets exploited by advertising scripts — a sure way to drain your battery power.

5. Adjust screen brightness
The brightest lightbulbs consume more energy, same is true for your screen's lighting. In your Preferences, look up Displays settings and do a couple of tune-ups there. Make sure to tick 'Automatically adjust brightness' checkbox.
6. Clean up your Mac
Macs battery benefits from various forms of cleaning. Why? Because the cluttered hard drive uses more CPU resources. The more strain on CPU, the more it affects and eventually wears off your battery. There are dozens of pretty good tools to remove hidden junk from Mac but my personal favorite is CleanMyMac X. It's so enjoyable to use even for such a trivial operation as deleting junk files.
- Download CleanMyMac X — here 's a link to a free edition
- Click on the System Junk tab
As you can see, I was able to remove 18.9 GB worth of useless files: caches, broken downloads, localizations, etc.
Sit back and know that with a tidy Mac, with it free from all of the clutter of years of use — and a monitoring system in place to look after it — your battery should be operating at optimum levels again.
