Are Safari Flags Slowing Down My iPhone?

Apple / How-To Geek

Unlike a desktop browser, opening tabs in the background on Safari will not slow down your iPhone. With some very limited exceptions, tabs are “suspended” and won’t use any resources until you interact with them.

If you’re worried that the huge pile of unlocked tabs in Safari for iPhone is slowing down your phone, reducing battery life, or wasting your storage space, then this is the article for you.

Safari handles tabs efficiently, so leave them alone

Listen, we understand. It’s totally normal to assume that opening a bunch of tabs in Safari on your iPhone should have some kind of effect. Just Feel As it should, right?

How can keeping hundreds, if not thousands, of tabs open on your iPhone harm performance, battery life, or both? And surely there must be a huge storage penalty to cache all those pages?

But this is implementing an old desktop-oriented model of web browser usage and impact on a mobile device that is designed to work in a different and more efficient way.

Despite all the claims you’ll find on the web and in viral videos that you should routinely close all tabs to improve performance, it just doesn’t matter.

When you’re not actively looking at a page in Safari, the page is in a suspended state. It is, in a sense, a glorified bookmark that happens to have a great thumbnail for viewing convenience. The number of tabs in Safari does not reduce battery life or make your phone run slower. If your phone needs resources, it will simply take over management of all the resources in the background without you ever interfering.

It’s very effective at this, in fact, despite our best efforts through extensive testing to replicate smaller Hit the performance to say, “Look! Under these extreme conditions, you can finally see the effect of excessive browser tabs on the iPhone!” We came up empty-handed.

We have uploaded thousands of tabs. We tried to force web pages to stay active in the background and drain the battery. We logged into the web-based resources we controlled and watched for prolonged activity indicating that the respective browser tab was doing something, anythingAbsolutely.

The final result? Hard evidence that the Safari experience on iPhone has been optimized to have as little impact on the user’s overall mobile experience as possible.

Nothing we did decreased performance. Playing music from a webpage loading in the background (which is one of the only ways the site will stay active even when you’re not interacting with it directly) hasn’t had the added effect of battery life that you won’t get from playing any music at all continuously on your iPhone your.

Just like closing apps on your iPhone has no effect on performance (and actually hurts performance and battery life), spending a lot of time fiddling with Safari tabs does nothing to make your phone faster or your battery last longer. And there is no storage performance affected either, because once your phone needs space occupied by any web page cache, it will occupy and use the space.

But shut them down if it makes you happy

So when should you close tabs? Not speeding up your phone because, unfortunately, this is just a placebo effect that makes you feel better.

Instead, close the tabs when it helps your mental health and makes you feel happier. Whether you want to start each week with a clean slate, have tabs open about a work project you don’t prefer to think about anymore, or for any number of reasons you don’t want tabs cluttering your phone, feel free to get rid of them all.

In fact, you can even set up your phone to automatically close tabs on a schedule. Again, it won’t have any effect on performance, but who doesn’t love a little bit of automation? Setting up a tab close schedule is like getting a little Roomba for your digital leftovers.

Don’t bother and don’t want to bother closing it? This is also good. I dont do. You can open Safari on my phone at any time, and save those rare moments when I close tabs for the purpose of writing articles here at How-To Geek, it’s always tied to a maximum number of tabs.

Hey, while we’re talking about tabs, check out all these tips and tricks to wrangle your pile of Safari tabs to keep them organized (or not) as you prefer.
