Battery Drain Mac OS

The Big Sur battery drain problem is something reported by many users who have recently updated their Mac computers to the Big Sur version of macOS. There could be a number of causes for the Big Sur battery drain problem, each requiring a different fix.

Several users have reported that their Mac’s batteries were draining faster even though the computer is in sleep mode. According to reports, users experienced an average of one to two percent battery drain per hour of the Mac sleeping. The rate of draining is higher on older Mac models, with up to 30 to 50 percent loss in some cases.

Every new upgrade to an operating system brings its own bugs and issues. Even though new major updates are beta tested for many months before being made publicly available, one or two bugs still manage to creep through. One of those bugs seems to be the battery draining in Big Sur. This is often accompanied by MacBooks getting very hot and fans working hard to keep them cool. Here’s why it happens and what to do about it.

Why does the battery drain faster after an update to Big Sur?

The nail reason is that after an update, your Mac needs to re-index the Spotlight database and other file databases, including Photos’ library. This is a CPU intensive task that can drive the processor hard and consume energy, draining the battery more than it would typically do.

However, in macOS Big Sur, there seems to be something else going on. Many users have reported that they found that a process called “kernelmanagerd” was consuming lots of CPU cycles.

CleanMyMac X has several tools that optimize your Mac and keep it running smoothly. One of them is the Maintenance utility: it frees up your Mac’s memory and runs useful system optimizations. Download CleanMyMac X here and run maintenance scripts — you may be able to fix the problem with battery drain in Big Sur.

What is “kernelmanagerd”?

Kernelmanagerd is a process that manages kernel extensions, or kexts, in third-party applications. It appears that what is happening is that some third-party apps are having trouble with kernel extensions, causing kernelmanagerd to work hard to resolve them and thus consume lots of CPU cycles.

How to tell if the kernelmanagerd process is causing problems

Go to Applications > Utilities and launch Activity Monitor.
Click the CPU column to order processes by the CPU cycles they are using.
Look for a process called “kernelmanagerd.”
If you see it and it’s consuming close to or more than 70% of CPU cycles, that’s why your battery is draining more quickly.

Spotlight app can also be the reason why your Mac battery drains quickly. After the upgrade, Spotlight starts making new indexing of the disk, which can last up to two days and consume lots of energy.

Here’s how to check whether Spotlight is still indexing:

Click on the Spotlight icon in the menu bar in the top right corner.
Type a couple of characters into the search bar.
If you see a progress bar with “Indexing…” in it, that means Spotlight is indexing and probably consuming a huge number of CPU cycles.

If Spotlight is indexing, the only thing you can do is wait. The good news is that when it’s done, your battery will be back to normal.

If you checked Activity Monitor for kernelmanagerd and found it consuming CPU cycles, the culprit probably is some software. Users reported that both Sophos Home and Malwarebytes caused kernelmanagerd to consume lots of CPU cycles and battery power, but these apps are likely not the only ones. Other programs that tend to work in the background can also drain your Mac.

You can use CleanMyMac X to remove any app and its data. CleanMyMac X allows you to uninstall many apps in one go, which is incredibly useful if you have lots of programs you don’t use anymore.

Reduce the load on the CPU

One of the biggest contributors to an overworked CPU is having a large number of browser tabs open. While this is convenient, it consumes RAM and puts pressure on the CPU, draining battery life. This is especially true if you’re using Google Chrome.

You should also make sure that Chrome and other web browsers are up to date and disable any extensions you don’t use.

It’s a good time to review login items, too. These processes launch when you boot your Mac and run in the background. They may also be reducing battery life. To disable startup items, go to System Preferences, and then navigate to Users & Groups. Here, select the apps that are launching on Mac’s startup and disable them by pressing “—.”

There are a number of reasons why your Mac’s battery might be draining more quickly after you upgraded to Big Sur. Fixing them could be just a matter of waiting for Spotlight to finish indexing, or you might need to take further action. https://inet-soft.mystrikingly.com/blog/casinos-in-louisiana-near-texas.

A low battery warning message can send a Mac user's work session into a tailspin if there's no readily available power source to turn to for rescue. It could be much worse for Mac users whose battery drains fast after upgrading to macOS 10.14. Fixes for MacBook pro battery life problems on macOS 10.14 are an easy-peasy affair because battery problems are usually not linked to bugs or any technical mysticism. Whether your old MacBook's battery issues are symptomatic of the battery's old age, or your MacBook Pro puts up low battery warnings one too many times in a day, the solutions to Mac battery problems on macOS 10.14 are a simple and straight forward.

Top 6 Common Battery Issues and Fixes on macOS 10.14

Issue #1: Your MacBook Is Not Charging

Possible Cause: The root cause of this issue is most probably the power source or charger, not the battery or the device. A damaged or dirty wall adapter may fail to power your MacBook Pro. If your charger sparks or its LED light does not turn when you plug it to the wall adapter, then the charger is culpable.

How to fix Macbook battery running out quickly on macOS 10.14: You can try any or all of the following:

Clean up the charging port, and the MagSafe connector.
Ensure the MagSafe connector's pins are properly set.
Try out a different wall adapter.
Ensure that the adapter's wattage is compatible with your MacBook.

Issue #2: The Battery Doesn't Charge to 100%

If the charging stalls between 93% and 98%, it's due to a bona fide macOS 10.14 feature that protects the battery from wear resulting from brief charging cycles. But if charging stalls below those percentages, then it must be due to battery charge calibration and indicator problems.

How to Fix: First, allow your MacBook Pro to calibrate the battery. To do this, charge the Mac to 100% and then unplug and use it until the battery drains down to 0%, and the Mac shuts down on its own. And then, after 5 hours, turn on your MacBook. If that doesn't fix this MacBook pro battery life problems on macOS 10.14, then reset your SMC. Turn off your Mac, and then press down 'Shift' + 'Control' + 'Option'+ Power button for 10 seconds, and then release them all at once. Afterward, hit the power button once to boot your Mac.

Issue #3: Battery Draining Fast When You Work

Possible cause: During the initial setup of the new Mac, Mac apps gobble up more battery power than normal. Your battery might drain fast when you're working on your Mac because, for one reason or another, you're running one-too-many apps at the same time. If your battery is draining fast after upgrading to macOS 10.14, it might be due to some default settings.

4. Battery Use Alert That Says 'Replace Soon' or 'Replace Now'

Possible Cause: Your battery may be due for a replacement because it has become decrepit as a result of shelf-life expiration or physical damage sustained from physical impact.

How to Fix: First, check the battery's health status. Open the 'Apple Menu,' and then press down the 'Option' key, and as the 'About this Mac' option changes into 'System Information,' select the latter, and then select 'Power' on the left side of the next screen. If the battery condition indicated here says something positive like 'Fair' or 'Normal,' then the battery life is still extant. But if the indication says something negative like 'Poor' or 'Check battery,' then your battery has become a write-off. Nonetheless, it is advisable to change your battery only at an Apple outlet.

Issue #5: My Battery Isn't Recognized

Possible Cause: When your Mac's battery's charge is completely depleted, it shuts itself away in a low power state to safeguard its ability to charge, and this might lead to it failing to register on the system properly.

How to Fix: To fix Macbook Pro battery life probems on macOS 10.14, connect your Mac to a power outlet and let it charge for at least five minutes. If the problem still persists, you may need to reset your SMC (see how to fix issue #2).

Possible Causes: This issue is most likely caused by user settings for battery status display.

How to Fix: Open 'System Preference' in the 'Apple Menu' and then select 'Energy Saver,' and then check box beside the 'Show battery status in menu bar' option.
