Your MacBook battery drains too fast? Try these 9 fixes
In this article, we’ll look at common problems and 9 fixes for these MacBook and MacBook Pro battery problems.
Why does your Macbook die so fast?
There can be several reasons. For example, different browsers consume different amounts of battery power.
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. Here are other reasons:
|Poor battery health||If your Mac’s battery is too old or damaged, it won’t hold charge for as long as it used to.|
|Wrong settings||Some basic settings consume too much battery charge; other settings may have been changed by accident, leading to battery draining.|
|Overuse||The more apps are used simultaneously or run in the background, the more likely the battery will drain faster.|
Below, we cover nine of the most common problems and fixes for Mac users, particularly MacBook owners who have suffered from a fast-draining battery.
9 solutions for Mac battery problems
1. Check and change Battery Settings
In the top menu, where the battery appears, it’s always useful to check out battery percentage so that you can clearly see how fast it’s draining.
If you click on the battery icon, it will show which apps are using the most power.
- From here, click Battery Settings.
- Within this, you’ve got the option to enable Low Power Mode, wake for network access, or optimize video streaming.
2. Check battery health
Battery cycles are a number of charge-discharge phases the MacBook battery can take in its life. Yes, this is a relatively fixed number. Count cycles are much more informative in terms of battery health than your basic charge indicator.
Open Apple menu > About this Mac > More Info > System Report.
Scroll down for Power specifications.
The average MacBook battery can go through 1000 cycles. Although this gives you some understanding of your battery condition, you may want to look for more details. CleanMyMac X, an Apple-notarized Mac app, has a handy Menu that helps monitor and control your battery health. Here’s how to use it:
- Download CleanMyMac X — a link to free download.
- Install and open the app.
- Go to your menu bar and click the CleanMyMac X icon.
Here, you’ll see the Battery section — click it to check your battery health, charging cycles, temperature, and more. CleanMyMac X will keep you informed if your battery overheats or is reaching its cycle maximum.
3. Manage power adapter preferences
It is always useful to do so 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 Settings > Lock Screen.
- Now, find the options saying “Turn display off.”
- Check the time options available to ensure the screen goes dark after a reasonable amount of time when not being used, which should reduce battery drainage.
- Now, go to System Settings > Battery > Options.
- Uncheck the box next to “Enable Power Nap while plugged into a power adapter.”
4. 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:
- 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.
5. 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, ransomware, or other viruses, either designed to steal data or 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 use your Mac for something you aren’t even aware of. 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 reset 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 that are otherwise nonvisible to a user. This very often gets exploited by advertising scripts — a sure way to drain your battery power.
As you can see, these items can be easily switched off using the Disable button.
6. Reduce screen brightness
The brightest lightbulbs consume more energy; the same is true for your screen’s lighting. In your System Settings, look up Displays settings and do a couple of tune-ups there. Make sure to tick the “Automatically adjust brightness” checkbox.
7. Turn off Bluetooth
Bluetooth is a valuable technology. However, if it is constantly turned on, it may significantly drain your battery. The thing is that it is always searching for paired devices, thus consuming resources. So, turning it off may prolong battery life.
To turn Bluetooth off:
- Find the Bluetooth icon in the menu bar and toggle the switcher.
- Alternatively, go to System Settings > Bluetooth and turn it off from there.
8. Replace the battery
Sometimes, none of the abovementioned tips will make a significant difference. It is because the battery may be too old. As we’ve mentioned, the average Mac battery can survive around 1000 cycles; after crossing the limit, it needs to be replaced. In other cases, it may have been damaged, and it is why none of the tips work.
Either way, the best thing to do is to replace the battery. If you have an older MacBook — a model released around 2008 — you can do it yourself. Still, it is a safer option to book an appointment with a certified repair shop and have it done for you.
9. Keep your Mac updated
As mentioned, sometimes, battery drain may be caused by software glitches. It may be either an outdated macOS or the one with bugs. Either way, it is a good idea to keep your Mac updated, as newer macOS versions come with numerous improvements and features that may prolong battery life.
Here’s how to check for updates:
- From the main Apple menu, navigate to System Settings.
- Go to General > Software Update.
- If an update is available, click Update Now and follow the on-screen instructions.
The same goes for updating all the apps you have installed on your Mac. But there are different ways to do it:
- For apps downloaded from the developer’s website, you will have to install newer versions manually. To do it, open an app one by one, click on its name from the menu bar, and find the option telling Check for Updates. Besides, check whether the automatic updates option is present in the app’s settings and turn it on.
- Built-in apps, such as Safari, update with every major macOS update.
- For those downloaded from the App Store, open App Store and navigate to Updates in the sidebar. Click Update All.
And that’s the end of our article!
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.
