The Most Usual Issues of MacBook Pro Battery

The Most Usual Issues of MacBook Pro Battery

Hello, my friends!
Today, I want to talk about common issues with MacBook Pro batteries and what to do in case you've faced one.
I know how dreadful the message about running out of the battery power reserves is.
On new macOS-s it may say 'Low battery' cautioning you that the Mac will go asleep unless its cable will be plugged into a wall outlet.

If you are somewhere near a power outlet, you hardly will get nervous when seeing such a message. The solution is simple! You need to get your charger, plug it into an outlet and see that your MacBook has gone back to its normal work.

Unfortunately, even this easy way may not be so simple in case you are using a MacBook with the old hardware that has battery issues from time to time.

If you see this warning more often than normal, or your MacBook's battery continues to bring you troubles, it is time to check the cause for issues and think about how they can be fixed.

The battery is more vulnerable to many issues than you can imagine. So, how can you help it? In this blog post, I'll try to analyze all the possible battery problems and try to get the most effective solutions for them!

By the way, I have recently found a cool app for Mac called Setapp, subscription to which allows me to save money and access more than 100 popular Mac apps. Try it too (Setapp it’s free for Download).

Did you know?..

Regular checking battery health is a nice practice. The most easy way I personally use is a software solution. I do it with the CleanMyMac X application.

Click on the app's icon on the Mac's menu bar. It will show an overview for the battery health. It will look like on a screenshot below. It will also tell you about the memory and storage usage and the size of the Trash bin.

The application can also offer a set of useful utilities for finding and removing junk files, uninstalling apps, managing startup items and a plenty of other effective instruments.

The life of Mac's battery is not consistent all the time. Temperature variations, usage styles, and other settings can influence its life. Such things should be considered prior to other hardware problems.

Your habits can make the battery live or die. Extensive multitasking, working with resource-hungry applications and other bad habits may significantly shorten the battery life. So, if you're using a MacBook, be careful with such a working style.

Battery issues almost never happened due to bugs. When you have new macOS and new software, Apple rarely will surprise you with bugs. If your software is updated, try to check hardware errors or usage patterns, they may cause you problems.


Mac's battery loses energy faster than usually

1. Overuse by apps or by you

A possible cause for this issue: if you notice that the battery loses energy twice as fast, maybe it happens because you use the machine twice as much. Remember whether there were changes in your workflow, maybe you started performing multitasking processes. These reasons can really ​cause battery drains.

How to fix it? Find out what applications are draining the battery power the most. Choose the battery icon, it is at the right top of the screen. It will show you all apps that are using MacBook's battery at the moment. This way, you'll get an idea which ones are the culprits for your battery problems.

You may limit the amount of apps that can be left in the background to decrease the battery drain. That will reduce the multitasking amount and surely will help.

2. Wrong settings

A possible cause for this issue: You MacBook's default settings eat the energy while you work with the machine.

How to fix it? There are several settings that may be changed, and the battery drain will be reduced.

  • Bluetooth. Don't you use any Bluetooth accessories at the moment? Turn it off! FInd an icon in the menu bar at the top of your screen and click on the 'Turn Bluetooth off' line.

  • Brightness of the screen. Making the screen not very bright, even by several degrees, is much better both for the battery and your eyes. If you are using an old MacBook, tap the F1 function key to make the brightness lower. In case you are a user of a new MacBook that have Touch Bars, tap on the icon with a sun on it.
  • Backlighting of the keyboard. MacBook Pro-s have a nice-looking keyboard backlighting. But there is no need to use it during the daylight time. You can adjust this setting with the F5 key or with the Touch Bar (if you use a new MacBook Pro).
  • Energy saver. Go to 'System preferences', choose 'Energy saver'. You can cut the amount of time after which your machine will go to the sleeping mode for saving the battery life.

After checking these preferences you may notice a considerable growth of the battery life. It will be clearly visible, if you used other settings before.


Your MacBook doesn't charge at all or to capacity.

3. Poor methods of storage

​​A possible cause for this issue: If you store your MacBook with a full battery or with no battery at all for a long time, there may be bad consequences. Apple also warns that leaving your device with 20% of charge or less for more than 2 days may take the same effect.

How to fix it? All MacBook Pro-s have lithium-ion batteries that should be charged for 50% or more before storing them for a few days or longer. If you need to store your MacBook Pro for several months, it's highly recommended to charge it to 50% or more every six months. This will help you to avoid losing battery resources. There are special storage instructions for older MacBooks, they can be found on the Apple support center.

4. A malfunction of a wall adapter

A possible cause for this issue: It may seem a bit strange, but the cause is not always inside your MacBook Pro. The wall adapter may cause problems. It may be dirty or damaged. It influences its functioning greatly. If you see some sparks while plugging the charger in, if its lights don't turn on, if your MacBook charges occasionally, it is likely to be the cause for the issues.

How to fix it? There are a few ways for fixing this problem:

  • Try another wall outlet.
  • Check the wire, split wiring and replace chargers.
  • Ensure that you are using the correct wattage charger for the MacBook Pro model. This information can be found on the Apple official website.
  • Clean the MagSafe connector and the charging port.
  • Look for the stuck down pins in your MagSafe connector. Try to put them to one side or dislodge pins, if they are stuck. You can see an example of stucked pins of the MagSafe adapter on my screenshot below.

5. A poor condition of your battery (it says 'Replace now' or 'Replace soon')

A ​​possible cause for this issue: The battery has reached its lifespan end or was damaged physically. This usually happens when a user drops the laptop by accident.

How to fix it? In the most cases, replacement of the battery is needed. Anyway, check the battery status before making any conclusions.

Go to the Apple menu at the top left. Hold the 'Option' key then. The 'About this Mac' line will change to 'System information'. Choose this line, click on the 'Power' button at the left. In the 'Power' tab, check the cycles and condition of your battery.

If its condition is positive like 'normal' or 'fair', your battery is okay. If it says 'check battery' or 'poor', it requires replacing.

What's more, compare the cycles number to this Apple's chart which says how many cycles your battery has. Your battery may function even after it reaches the threshold. However, it will lose its effectiveness after it happens.

In case you have found out that your battery needs replacement, I recommend going to one of the Apple service centers for doing that. In new MacBook Pro-s battery changing can be quite a problem for an average user. This guide will be a great assistant in getting a poor battery fixed.

6. It doesn't charge to 100%

A possible cause for this issue: In case your battery stops at 93-98%, it's not a great problem yet, It is made especially for preserving battery life. But if it stops below 90%, that is an issue already.

How to fix it? Before making some conclusions, try to charge your MacBook Pro to 100% and keep it plugged in during a couple of hours. Unplug the adapter and drain the battery to 0%. Wait until the machine shuts down by itself, then wait 5 hours more and charge it again. Doing this will calibrate the battery.

If that didn't work, try to reset the SMC (System management controller), it can also fix the battery charging. Take the following steps, if you are a user of 2009 MacBook Pro or later:

  1. Shut your MacBook down.
  2. Hold 'Shift+Control+Option' combination, then tap on the power button for 10 sec.
  3. Release the keys.
  4. Boot your MAcBook again.


Here is a guide on resetting the SMC for those who use older machines than 2009.



Problem with batteries really suck. They influence productivity, generate uncertainty and seem terrible. However, my guide identifies the main reasons for the battery draining, so I hope that you have found the best solution for you and now are able to fix your problem!

If none of them worked, try to contact the Apple support team. I'm sure they will help you!

Finally, I hope you won't face serious battery issues and will enjoy its long time functioning! Subscribe, if you liked this article!
