Delete Unused Apps/Games

From time to time, you may forget about the apps or games you downloaded from Apple Store. The sad news is that the unused apps not only take up a lot of space but also consume the CPU resource of your iPhone, either because of background refresh, notifications, or something else, leading to slow iPhone response. Therefore, it's an essential way to speed up iPhone 8/X/7s/7/6s/6/SE/5s in iOS 11/10 by getting rid of some apps and games you never use.

Step 1: Just press the icon of the app or game you'd like to delete for few seconds until the apps wobble and the "X" icon on the top-left corner of the apps appear.
Step 2: Click X icon to delete the app or game.

Or you can go to Settings -> General -> Usage -> Manage Storage where you can see which apps eat up the space memory and  how much storage space is left. Then delete the unwanted apps. Frankly, 1GB space will be good to speed up iphone.

Good News: It is one of the iOS 11 problems that it slows down older iPhone 6S/6/5S/5/SE. Being aware of this, Apple is making enhancement of the latest iOS 11. So far, iOS 11.3 adds a new battery health checking feature to help boost iPhone speed. As on older iPhones, iOS 11 will slow iPhone to prolong the battery life. But with iOS 11.3's Battery Health feature under Settings > Battery, users can check the battery and close any app accordingly. Among which, automatically Offload Unused Apps is a must mention. Your iOS 11 iPhone 8/7s/7/6s/6/5s/SE can full-automatically delete unused apps without your involvement as long as you go to Settings > iTunes & App Store > Enable "Offload Unused Apps".

Don't worry! All the data from the auto deleted unused apps are saved on your iPhone and you can also restore the deleted apps back on iPhone by slightly clicking on the app icon on your iPhone desktop.

update ios to speed up iphone

Upgrade iPhone to the Latest iOS 11 or Not

A big iOS update means a faster performance on iPhone or iPad. So updating iPhone to latest iOS can speed up iPhone to some extent. To update iOS 11, just go to Settings -> General -> Software Update. But there are exceptions that we don't suggest you updating software for iPhone speed boost:
1. iOS problems. Psychologically, older phone seems to be slower compared to newer ones. But the real iPhone slowness correlation is that newer iOS is synchronous with newer iPhone models and each iOS updates tend to make older hardware run slower. The typical examples are the iOS 8 and the latest iOS 11. One of the big problems with iOS 8 update is the huge memory consumption, leading to insufficient space for other tasks and slow iPhone performance. In this case, you'd better to wait until the iOS is stable and then upgrade to the new iOS to fix the bugs. As to the lateset iOS 11, a controversial decision is made by Apple to ensure there is no unexpected shut down of the older phones at the expense of slowing iPhone's processing power.

2. Incompatibility. Each iOS update means incompatibility with elder iDevice models. For instance, the iPhone 4 and earlier models are incompatible with iOS 8 upgrade; only iPhone 5S and newer models support iOS 11. Whilst users of older iPhone 4S or older models won't enjoy the privilege of new iOS for iPhone speedup.

3. iOS power consumption. Bear in mind, iOS 11 brings you a lot of amazing features and generally gives iPhone a boost in speed though, more and more power is required to run it to fight against the sluggish performance on iPhone iPad. That's why the new iPhone like iPhone X has faster processor than the iPhone 7 or predecessors. But for the older model like iPhone 6 or below, updating to iOS 11 will actually slow it down, because it struggles to run the demanding iOS. That's why many iPhone 5S users reported a slow performance on iOS 10. So we don't expect any faster performance on iOS 11 as well. If you report the iPhone slow problem after updating to iOS 11, please downgrade iOS 11 to iOS 10, which will somehow speed up iPhone.
