Why Is My MacBook Battery Draining So Fast? (Explained)


Why Is My MacBook Battery Draining So Fast

If you have a recent macOS, it may indicate “Low Battery,” meaning your Mac will sleep shortly unless plugged in. Unfortunately, this warning is frequently ignored when near a wall outlet. As a result, your MacBook Pro is now back to normal when you plug in the charger. But unfortunately, it isn’t always that straightforward, especially if you have an outdated MacBook Pro with difficulties like battery loss and other concerns. 

So if this warning appears too frequently or the battery continues draining fast, it’s time to diagnose and rectify the issue. This post will explain why my MacBook battery is draining so fast and provide alternatives.

Here are possible reasons for “why is my MacBook battery draining so fast,” using too many apps or browsers, having the wrong settings and storage method. Other causes may be a failed wall adapter connection, a poor battery condition, and maybe the battery does not charge. 

Why is my MacBook battery draining so fast?

This might be for numerous causes. For example, battery consumption varies by browser. In rare circumstances, a recent macOS upgrade might cause a temporary issue. Or a new macOS patch/upgrade is provided, and once received, the problem goes wrong. Unfortunately, it’s common around new releases, and many Mac users expect it.

In other circumstances, the issue is more localized. We examine five of the most prevalent problems Mac users face, especially those with a rapidly depleting battery.

Using Too Many Apps 

Using your battery twice as much may lead it to deplete twice as rapidly. Especially if you recently changed your workflow, such as boosting your multitasking, this might cause abrupt battery loss.

Wrong Settings

Your computer’s default settings are sapping your vitality. For example, your MacBook Pro won’t charge fully or at all.

Wrong storage method

If you put your MacBook into extended storage with a full or no battery, the battery will suffer. Apple also warns against keeping lithium-ion MacBooks uncharged for more than two days.

Wall Adapter Fails

The problem isn’t always with your computer, but with the wall adapter, you’re using to charge it. A broken or unclean wall adapter will not charge your MacBook Pro. The charger is likely to blame if the computer only charges sometimes or if the charger’s LED doesn’t light up.

Poor Battery Condition

Your battery is dead or has been physically damaged by a laptop drop.

Battery Doesn’t Charge.

It’s quite normal if it stops charging between 93 and 98 percent. It’s a safety feature that keeps short charging cycles from damaging the battery. If it’s not at least 90%, you may have a problem.

How to fix the MacBook battery draining so fast

Fix Overuse problem

The most power-hungry applications are shown by a battery symbol in the upper right corner of your Mac. In addition, this will show you which applications are presently consuming the most power.

Fix Wrong Settings

Changing a few basic settings could help save battery life on your MacBook Pro while you work:

  • Turn off Bluetooth while not using any Bluetooth equipment. Select “Turn Bluetooth Off” from the menu bar’s Bluetooth icon.
  • Less screen brightness is beneficial for your eyes and the battery. Press the function key F1 to dim the screen on an earlier MacBook. Those using Touch Bar should use the smaller sun symbol.
  • The keyboard on MacBook Pros is quite bright, so you may wish to adjust it using the F5 function key.
  • For macOS Big Sur, select “Battery” or “Energy Saver” from the System Preferences menu (for macOS Catalina or earlier). Make it easier for the computer and display to shut down and sleep.

Doing so should significantly improve battery life, especially if you previously utilized drastically different settings.

Eliminate Inefficient Storage Practices

Lithium-ion batteries in most MacBook Pros should be charged (or drained) to 50% before being kept for more than a few days. Every six months, you should charge your computer to 50% to prevent battery capacity loss.

Older MacBook Pros may utilize other batteries that require different handling and storage procedures. 

Fix Wall Adapter Not Working

You can resolve this issue in numerous ways:

  • Change the wall outlet.
  • Replace chargers with frayed insulation.
  • Verify that you’re using the correct wattage adapter for your MacBook Pro by visiting Apple’s official website.
  • Disinfect the charging port and MagSafe.
  • Look for crooked pins in the MagSafe connection. If any are, gently press the pins to one side to attempt to remove them.

Fix a faulty battery

You’ll probably need a new MacBook battery. But first, verify your battery’s state. 

  • To begin, select the Apple menu in the upper left corner. Then hold OPTION. “About This Mac” becomes “System Information.” Select System Information, then “Power” on the left.
  • To check your battery’s state, go to the Power tab.
  • If the condition is “fair” or “normal.” If it reads “poor” or “check battery,” your battery is probably dead.

Compare the number of cycles to Apple’s chart showing how many cycles your Mac’s battery will survive before deteriorating. Batteries will still work after this point, although less efficiently.

If you need to change the battery, it is suggested that you do it through Apple. This is because newer MacBook Pros are less likely to allow manual replacement. If you are experienced with computers, you should be able to accomplish the assignment on your own.

Fix a battery that won’t charge

Charge your Mac to 100% with the adapter and use it for two hours before attempting a more sophisticated solution. Then disconnect it and let your MacBook’s battery deplete to 0% before shutting off. Wait 5 hours, then turn on your MacBook. Now calibrate the battery. If calibration doesn’t work, try resetting the MacBook SMC (System Management Controller).

Manage Power Adapter Preferences

Doing so helps save battery power on any device, and it can save your life if you are without a power cable or socket.

  • Go to the Apple menu;
  • Battery under System Preferences.
  • Go to the Power Adapter tab.
  • This screen should include a slider so that the screen turns black to save power when not in use.
  • Uncheck the “Enable Power Nap when plugged in the adapter.”

What is using energy?

Before researching a fast-draining MacBook battery, knowing what uses energy is always good. Steps to find out:

  • Go to Apps;
  • Activity Monitor > Utilities
  • Activity Monitor will reveal CPU and GPU use.
  • Allowing you to close anything that is blatantly consuming too much battery.

Find hidden applications

Most Macs can run hundreds of programs without our knowledge. Some of these may be running due to our negligence, while others appear during bootup. Others, without our knowledge, may be spyware, ransomware, or other infections meant to steal data, process power, or even perform remote DDoS assaults.

That’s not ideal, and you don’t want programs draining power, stealing data, or using your Mac in ways you’re unaware of.

Dim screen brightness

The brightest lightbulbs and screens use more energy. Look up Displays settings in Preferences and tweak them. Make sure “Automatically adjust brightness” is selected.

Conclusion

Battery life varies according to temperature, use, and settings; all influence performance and should be considered before hardware concerns. In addition, MacBook battery life is affected by habits. Whether you realize it or not, excessive multitasking and resource-intensive applications are significant battery-punchers. Consider these when using your MacBook.

Bugs rarely cause battery concerns, and Apple still has a few unsolved problems unless you have the latest software and macOS. This suggests use patterns or hardware issues are probably causing your issue.
