Tips to Speed Up Your Old iPhone


You may notice that your old iPhone 6, 6s or SE is getting slower. It’s not just your illusion. From the update of iOS 10.2.1, Apple started slowing down the iPhone 6, 6s and iPhone SE in order to prevent sudden shutdowns. Apple admitted it in an official statement:

Our goal is to deliver the best experience for customers, which includes overall performance and prolonging the life of their devices. Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, have a low battery charge or as they age over time, which can result in the device unexpectedly shutting down to protect its electronic components. 

Last year we released a feature for iPhone 6, iPhone 6s and iPhone SE to smooth out the instantaneous peaks only when needed to prevent the device from unexpectedly shutting down during these conditions. We’ve now extended that feature to iPhone 7 with iOS 11.2, and plan to add support for other products in the future.”

If you don’t have a plan for a new smartphone and want to speed up your old iPhone. You should continue your reading. 


Tips to Speed Up Your Old iPhone

1. Replace your iPhone’s battery

After reading the statement cited above, you may find the real reason, why Apple slow down your iPhone, is to protect the electronic components and prevent suddenly shut down caused by lack performance of the battery. If you doubt the slow down is due to the bad battery performance, you can check it by yourself first before you seek for maintenance service. Open App Store> Search for coconutBattery or other battery checking app> to see whether you need a battery replacement

How to get your iPhone’s battery replacement at Apple Store or Apple authorized service provider? Head to Contact Apple Support page> Click See Your Product> Select Battery, Power, and  Charging> Select Battery Replacement> Bring in for Repair> Choose a nearby store> Book a Genius Bar appointment> Bring your iPhone to fix. Apple has reduced the price of battery replacements for the iPhone 6 and newer to $29, down from $79, as part of its apology over a lack of communication about the power management changes it made starting in iOS 10.2.1. The discount is effective immediately and available until the end of 2018. 

2. Clean up some space

Head to Settings > General > iPhone Storage. Here, you’ll see a colorful chart that shows you how much space you are using and how much free space you have remaining. Below the chart you’ll get a few recommendations about how to save storage, including the newfound ability to Offload Unused Apps, enable iCloud Photo Photo Library, Auto Delete Old Conversations (texts and attachments more than a year old) and Review Large Attachments. Then you can visit the apps which take much space and clean it up, such as delete some message or caches. You can also delete some apps for more space.

3. Embrace high-efficiency format

iOS 11 introduces file formats for photos and videos that results in smaller file sizes. Photos and videos are biggest occupy of storage space for most iPhone users.

Go to Settings> Camera> HDR(HIGH DYNAMIC RANGE)> Turn on Keep Normal Photo

Go to Settings> Camera>Record Video> Choose 720HD at 30 fps

Go to Settings> Camera>Record Slo-mo> Choose 720HD at 120 fps

4.Update your apps

Old apps may not run as smoothly on the new iOS 11 without an update. After updating your iPhone to iOS 11, check to see if you’ve got app updates waiting. Open the App Store app, tap Updates and tap Update All to update your apps.

5. Cancel automatic updates

Updating apps in the background, however, is a process that occupies your device’s CPU (not to mention battery). You can disable this feature and update your apps manually via the App Store app. Go to Settings> iTunes and App Store> AUTOMATIC DOWNLOADS> Turn off Updates

6. No background app refresh

In addition to updating when you are otherwise occupied, apps also refresh their content in the background. Helpful, to be sure, but it occupies CPU cycles. Go to Settings> General> Background App Refresh > Tap the toggle selectively switch off behind apps

7. Turn off motion effects and reduce transparency

Apple uses a number of effects to give iOS a sense of depth as you tilt your phone or open and close apps. These motion effects generally improve your experience, but not if they result in choppy animations. Go to Settings> General> Accessiblility> Turn on Reduce Motion. You can also toggle off Auto-Play Message Effects, but it will reduce some of the fun of texting.

Go to Settings> General> Accessiblility> Increase Contrast> Turn on Reduce Transparency. This setting reduces the transparency and blur effects, ostensibly to increase legibility, but it can also serve to speed up performance because it’s one fewer graphics task for your device’s processor to handle.

8. Close location service for some apps

Location services decrease battery life more than performance, but if your iOS device is draining its battery at a faster clip with iOS 11, it’s time to cut down on the number of apps using your device’s GPS to request your location. Go to Settings> Privacy> Location Service> Tap the toggle selectively switch off behind apps

9. Reboot when there is a problem.

You can try restarting your device when there is any problem. Sometimes a simple reboot will put a little pep back in its step.

    1. My iPhone6 battery has been replaced recently. But not at Genius Bar. I called them and they told me my iPhone 6 couldn’t join this program since it was opened and fixed by others. Although what they told me didn’t appear in the official announcement, I found others who can help me to replace the battery. And now, my iPhone 6 works well. It can stay alive all day long. However, Apple service providers may not follow the same rules in different places. You should call them first.
