If you’re a remote worker who needs Windows on Mac wherever you go, Parallels Desktop is a great choice. Dell 3000cn driver download. Yes, virtualizing Windows takes a lot of battery power—but with Parallels Desktop 11’s new feature, Travel Mode, you can easily get access to Windows (no matter where you are) without sacrificing too much juice. If MacBook’s battery is draining while it is sleeping, it happens for two reasons: the Mac gets awakened periodically by an external event (network, Bluetooth signal, or peripheral hardware), or there is an application that runs on the background that does not let MacBook go to sleep.

In a CNET review earlier this week, the reviewer found that running Windows 7 on a MacBook shortened battery life from 5 hours under Mac OS X to just 90 minutes, a reduction of more than two. Whatever you are doing in windows, if it's processor intensive it will drain the battery. Just having the VM run and do nothing really doesn't drain battery. I recommend use the 'longer battery life' setting in virtual machine settings (Configurare the virtual machine, under options, there is an option on the left pane called Optimization). If I forget to Pause or Shutdown Parallels' Windows, it seems that overnight my battery can drain up to almost 30% sometimes, after I close the lid of the laptop. Can't disable Power Nap cos it's no longer an option.

Why is my Mac battery draining 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. We cover five of the most common problems and fixes for Mac users, particularly MacBook owners who have suffered from a fast-draining battery.

5 solutions for Mac battery problems

1. Check and change Battery Settings

In the top menu, where the battery appears, it’s always useful to switch usage to a statistics setting so that you can clearly see how fast it's draining.

If you click on the battery, it will show which apps are using the most power.

From here, click on Open Energy Saver Preferences
Within this, you’ve got the option to put the hard disks to sleep and dim the display when a Mac is not connected to power.

2. Switch on Energy Saver

Always useful 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 Preferences > Energy Saver
Now click on the Battery tab
A slider should be on this screen: Switch Power Nap off while sliding the scale along to ensure the screen goes dark after a reasonable amount of time when not being used, which should reduce battery drainage.

3. 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.

4. 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 or ransomware, or other viruses, either designed to steal data or steal 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 rest 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 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.

5. Adjust screen brightness

The brightest lightbulbs consume more energy, the same is true for your screen's lighting. In your Preferences, look up Displays settings and do a couple of tune-ups there. Make sure to tick the 'Automatically adjust brightness' checkbox.

6. Clean up your Mac

Mac battery benefits from various forms of cleaning. Why? Because the cluttered hard drive uses more CPU resources. The more strain on the CPU, the more it affects and eventually wears off your battery. There are dozens of pretty good tools to remove hidden junk from Mac. Still, my personal favorite is CleanMyMac X. It's so enjoyable to use even for such a trivial operation as deleting junk files.

As you can see, I removed 18.9 GB worth of useless files: caches, broken downloads, localizations, etc.

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.
