The Microsoft Edge browser has seen steady improvements since its introduction. It's fast, offers excellent synchronization, and can use a wide range of extensions. Microsoft has also focused on performance, not only of Edge itself but how Edge impacts a PC's overall performance.

One of the easiest ways to reduce Edge's performance penalty is to use efficiency mode, which reduces Edge's CPU use and puts background tabs to sleep after five minutes or less of activity if the sleeping tabs feature is enabled. Turning efficiency mode on and off is easy enough to do and can help keep your PC running smoothly.

Turning efficiency mode on and off

Efficiency mode can be configured to be always on, on when a laptop is unplugged, on when a laptop is unplugged and low on battery life, or never on. Enabling and disabling efficiency mode takes just a few steps.

Step 1: Select the Three-dot menu button in Edge, and select Settings, or use the Edge browser shortcut, Alt + E.

Step 3: Make your selection from the drop-down menu next to Turn on efficiency mode when, with options for Unplugged, low battery, Unplugged, Always, and Never.

The "unplugged, low battery" setting works differently on different platforms. On Windows, efficiency mode turns on when Windows Battery Saver mode turns on. On Mac OS, efficiency mode turns on when the battery hits 20%. On Linux, efficiency mode is off by default.

Step 4: You can also enable efficiency mode when you're gaming -- useful on any computer, not just games systems and gaming laptops. Just toggle on the option Improve your PC gaming experience with efficiency mode.

Step 5: Note that in order for efficiency mode to work, you need to have sleeping tabs turned on. When efficiency mode is turned on, tabs are put to sleep after five minutes or less regardless of how much time is set for "Put inactive tabs to sleep after the specified amount of time." To retain that setting, efficiency mode must be disabled.

Enable the performance button

To make it easier to turn efficiency mode on and off, unhide the performance button on the toolbar.

Step 1: Select the Three-dot menu button and select Performance. That will enable the performance button, which will show up as a filled heart.

Everything You Need in Your First Laptop Without the Luxury Price Tag 
The Dell 15 makes its case that budget laptops do not have to feel cheap, or sluggish.

The PC market has never been more diverse, and utterly punishing on the wallet, thanks to the AI boom and resultant price inflation we are seeing in 2026. Most people shopping for a pocket-friendly laptop don’t necessarily care about core counts, clock speeds, or refresh rates. They want something that opens Chrome quickly, plays Netflix without stuttering, and survives a few years of assignments.

For a long time, that was too much to ask. I’ve tested plenty of budget laptops that felt tired out of the box, with plastic that flexed under my palms and fans that roared every time I opened a few tabs. Most of them felt noticeably slower within a year.

Following Anthropic's lead, OpenAI is bringing its Chat and Work capabilities together.
Using ChatGPT on a phone.

OpenAI is making a few changes to how ChatGPT handles conversations and more complicated work. The company is now planning to merge the Chat and Work tabs into a single experience, allowing users to ask questions and get things done without having to switch between different tabs. The change will initially be available to select users before a wider rollout.

For the unaware, Anthropic made a similar change to Claude back in September, when it merged the Chat and Cowork functions into one screen.

The iPhone Duo taught the iPad a much-needed lesson in multitasking. iPadOS 27.2 makes Split View less of a chore.
A small iPad tweak that fixes a big daily annoyance.

It’s funny when a brand-new phone teaches an old tablet a lesson. That’s exactly what the iPhone Duo seems to have done for the iPad. I’m genuinely glad somebody at Apple was paying attention, as it was overdue.

iPadOS 27.2 makes setting up side-by-side apps on an iPad much easier, and it is an iPad multitasker’s dream come true if you ask me.
