macOS Sequoia battery drain

Is your MacBook battery draining fast after the Sequoia update? Some users have encountered significant battery drain on macOS Sequoia despite their Mac not doing heavy work or being in sleep mode. Is this a macOS Sequoia issue or a problem with your Mac? I'll explain the details in this post and tell you how to fix the macOS Sequoia battery drain.

Does macOS Sequoia drain battery?

macOS Sequoia itself isn't draining the battery but it may put more pressure on your Mac's resources, which draws more energy from your battery.

Each new macOS version tends to require more system resources than the previous one to support new features and functionalities. Besides, the latest macOS version is often optimized to take advantage of the hardware improvements of Apple's recent Mac hardware, which may not be well supported on older Macs. That's why each version is dropping support for certain hardware builds.

But if your Mac is supported and not significantly outdated, the battery drain may be temporary and can be resolved with the solutions I'll discuss in the next part.

If your battery life drops dramatically on macOS Sequoia, for instance, goes from 100% to 40% in about an hour and a half, try the following solutions.

macOS Sequoia battery drain during sleep or overnight

If you wake up and find your battery drastically or even completely drained on a Mac that was put to sleep last night, there are a few things you can do to stop your Mac's battery from going down so fast.

Wait while it's indexing

After a macOS upgrade, your Mac will typically undergo Spotlight reindexing to ensure that Spotlight and other services on your Mac have up-to-date information about the file system, compatibility with new features, and file metadata accurately reflected in search results.

This may take several hours or days to complete. If you just finished the update, keep your Mac charged and wait longer to see if the issue goes away.

Turn off WiFi/Bluetooth or modify their settings

When your Mac is in sleep mode, WiFi and Bluetooth are reduced to conserve battery life but they are not completely turned off. Your Mac can still wake up for network or Bluetooth activities. If Power nap is enabled, your Mac can also wake periodically to check for new emails, events, or iCloud updates.

The easiest way to prevent your Mac from wasting battery in sleep mode is to disable WiFi and Bluetooth before it enters sleep mode. However, if you want to keep WiFi on, you can modify WiFi settings instead:

  1. Go to System Settings > Battery.
  2. Click on Options.
  3. Avoid choosing Always for "Enable Power Nap," and "Wake for network access."Disable Power nap and wake for network access to decrease battery drain in sleep mode
  4. Click Done.

Unplug all unnecessary devices

External displays, USB hubs, or other devices connected to your Mac also use your Mac's battery when it's in sleep mode. If you have external peripherals plugged in, ensure you unplug them before putting your Mac to sleep.

Completely quit apps

It's also advised to completely quit all running apps on your Mac to stop battery drain in sleep mode. Some background processes may consume your battery power even when your Mac isn't active.

Check apps that are preventing your Mac from sleep

You can also find apps that use excessive energy in Activity Monitor by launching the app, selecting the Energy tab, and clicking on the column "Preventing Sleep" or "Energy Impact." Then remember always to quit them before your Mac goes to sleep.

Put your Mac in Low Power Mode before closing it

"Low Power Mode" is a feature designed to extend a Mac's battery life by reducing energy consumption. You can enable it to reduce macOS Sequoia battery drain during sleep. To do this, open System Settings > Battery and choose "Only on Battery."

Shut down your Mac

Why is the battery on your Mac draining so fast?

To understand why your Mac's battery is draining so fast, you must first look at the key factors that can contribute to battery drain on Mac.

  • High CPU or GPU usage: Intensive tasks that require a lot of processing power, such as gaming, or video editing can quickly deplete the battery.
  • High-level display brightness: Display is one of the most power-hungry components. If you keep your Mac at a high level of brightness for a long time, it will drain your battery massively, especially for large monitors.
  • Network connectivity: Wi-Fi and Bluetooth require power to maintain connections.
  • Background processes: Apps or processes running in the background can also consume your battery energy.
  • macOS updates: Major updates like macOS Sequoia can introduce bugs or features that negatively affect the battery life of your Mac.
  • Hardware degradation: Your Mac's components or battery degrades over time.
  • Hot Temperature: Exposing your Mac to extremely hot or cold environments can reduce its battery life.
