How to Turn off Background App Refresh on iPhone or iPad

By default, your iPhone (or iPad) lets apps check for new data in the background. It can reduce loading times when switching back to an app, but it also reduces battery life, takes a bit of cellular data, and could allow some apps to spy on you. Here’s how to turn “Background App Refresh” off.

First, open the “Settings” app on your iPhone.

Tap the "Settings" icon on iPhone

In “Settings,” tap “General.”

In Settings on iPhone or iPad, tap "General."

In “General,” tap “Background App Refresh.”

In General, tap "Background App Refresh."

Next, you’ll see the “Background App Refresh” settings. If you’d like, you can disable Background App Refresh on an app-by-app basis here. Just tap the switch beside each app you’d like to disable to turn it off.

In 2019, the Washington Post discovered that some apps use the Background App Refresh feature to send data about your activities through the internet when you don’t suspect it, so unless you completely trust an app vendor and think the refreshing is likely useful to you, it is probably best to turn the feature off for most of your apps.

In "Background App Refresh" settings, you can turn the feature on or off for individual apps.

Luckily, Apple also makes it easy to completely disable Background App Refresh. To do so, tap “Background App Refresh” at the top of the page.

Tap "Background App Refresh" again.

On the next screen, select “Off” from the list.

In "Background App Refresh," select "Off."

After that, exit Settings, and you’re all set.

Interestingly, Background App Refresh is one of the features that gets disabled when you enable Low Power Mode on your iPhone. Your iPhone will use less battery power in idle mode from now on.

MaxFreeTcbs regedit tweak

MaxFreeTcbs determines how many active TCP connections your computer can handle at any given time based on how much physical memory you have and how much performance your computer has with regard to bandwidth.

If the number is too high, your computer may not properly process TCP transactions because of the high amount of active connections talking to the computer at the same time. However, if the number is too low, you can’t host or request as many connections as you’d like. While the setting is arbitrarily determined, you may want to bump up the number when you upgrade your hardware or Internet connection.

What is MaxUserPort and how to modify it

When an application requests an available port to open from Windows, the operating system chooses one port from 1024 to a specified maximum known as “MaxUserPort.” A port on your computer allows you to establish TCP/UDP connections through the Internet and in your local network. What happens when you open more options to programs seeking a port? They find a port much faster than they would with only a couple thousand available choices.

Windows sets this value to 5000 by default, but you can set it up for any number from 5000 to 65534.

How to Add a Kids Profile to Google TV

Google TV devices, like the Chromecast with Google TV, are great at surfacing content to watch, but not all of that content is family-friendly. Thankfully, you can set up a specific profile for your kids, complete with parental controls.

You can have multiple profiles for everyone in your home on Google TV devices. The Kids profiles have a bunch of extra controls, including bedtimes, viewing limits, app monitoring, and more. Creating a Kids profile will add them as a member to your Google Family. It’s not the same as creating a Kids profile from scratch, as you won’t be assigning them a Gmail address.
