iPhones are usually very snappy and responsive, and they normally stay that way for years. However, if you have an older iPhone, it might be getting slower over time, right? Well, don’t worry. Here are 7 foolproof ways to speed up your iPhone in 2025.
1. Replace the Battery (For Older iPhones)
If you’re rocking an older iPhone, chances are the battery health has really gone downhill by now. And even though you might be okay with the short battery life, the constant recharging, and every other headache that entails, the issue is that a degraded battery will slow down your iPhone.
This happens because as your iPhone battery gets older and loses its charge capacity, your CPU starts getting voltage throttled, and therefore, the performance takes a big hit.
So the easiest thing to do with your old iPhone is to get a battery replacement. That should give you a pretty noticeable performance boost.
2. Clean Up Your Control Center
Whether you have an old iPhone or a new one, this is one setting that makes a big difference to your iPhone’s performance and can speed up your iPhone.
If your Control Center has a lot of toggles that you don’t use, remove them right away. For some strange reason, having a lighter Control Center considerably improves the speed of your iPhone. This is especially noticeable if your iPhone is getting slower, because new iPhones are typically so fast anyway that you wouldn’t really notice a performance boost even if there was one.
3. Enable Reduce Motion
Another thing you can try to make things appear snappier on your iPhone (old or new) is to enable the “Reduce Motion” feature.
- Just go to Settings -> Accessibility -> Motion
- Here, turn on the Reduce Motion toggle
Basically, this will remove app-closing/opening animations along with some other animations, and make your iPhone appear faster. This is more like the animation speed settings in Android phones, so it can make you feel like your iPhone is working faster than before.
4. Enable Reduce Transparency
Another setting that can speed up your iPhone is the “Reduce Transparency” option. This, along with the Reduce Motion option (as well as the next two options on this list) can make an decent difference to your iPhone.
- Just go to Settings -> Accessibility -> Display & Text Size
- Turn on the “Reduce Transparency” toggle
5. Disable “Hey Siri”
Most iPhone users have the “Hey Siri” or “Siri” voice command enabled on their iPhones for no reason other than the fact that the first-time set up had them set it up. Well, that needs to change.
Disabling the “Hey Siri” voice recognition feature on iPhone can improve your iPhone’s performance. I’m not exactly sure why this works, but it does work. Maybe because your iPhone doesn’t have to keep its proverbial “ear” open all the time waiting for the Siri command that will never come?
- Just go to Settings -> Apple Intelligence & Siri -> Talk & Type to Siri
- Tap on the “Off” option to disable the voice command
You can keep using Siri with the side button or the double-tap on the bottom edge of your iPhone features. Those will not impact performance as much.
6. Free Up Storage
One of the leading causes of slow iPhones is the storage. See, iPhones have historically had storage issues, what with 64GB base models up until a few years ago, and there being no option to clear app caches in iOS, the internal storage fills up quite quickly.
If your iPhone storage is nearly full, it will impact performance at every step of the way. This means it is imperative for you to do some storage management from time to time.
- Go to Settings -> General -> iPhone Storage
- If there are apps using too much storage, try and delete some files from those apps
- Some apps, like Instagram, might have a huge app cache which can’t be deleted. The easiest thing to do in that case is to uninstall the app and then re-install it. That will get rid of all the downloaded data, and you can free up some storage on your iPhone.
Pro-tip: You can also use the “Offload Apps” option to automatically offload apps that you haven’t used for a long time. This way you can save storage space easily.
7. Last Resort: Factory Reset
If you’ve done everything on this list and you’re still unhappy with the performance of your iPhone, the only thing left for you to do (short of upgrading to a new iPhone) is a factory reset.
This has plenty of benefits: you get a fresh, clean slate. You get completely empty storage, no unwanted cache, files, or anything. You can then proceed to restore a backup, or just use your iPhone as new.
Either way, this should give your iPhone a performance boost.
- Go to Settings -> General -> Transfer or Reset iPhone
- Tap on “Erase All Content and Settings” and then tap on “Continue“
- Follow the prompts on screen to factory reset your iPhone
Well, those are the 7 best ways to speed up your iPhone in 2025. I have included easy to follow methods in this list so that anyone can easily turn their iPhone from a slow, sluggish brick of a phone into a fast and snappy iPhone once again.
