It is generally good to keep your iPhone apps updated–as app updates usually contain new features or bug fixes.
Apps are updated all of the time, and depending on how many apps you have downloaded on your iPhone, every day there could be a lot of apps to be updated. When you turn on automatic updates for apps, new versions of apps that you currently have on your iPhone will automatically download when updates for those apps become available.
This post will explain how to turn on auto-updates for apps–just note the tip at the end of the post about how to avoid using data from your iPhone’s cellular data plan when updating apps.
Simple Quick Instructions: [Settings -> iTunes & App Store-> Toggle “Updates”]
Simple Step-by-Step Instructions:
First, open the “Settings” app on your iPhone.
Next, scroll down and tap on “iTunes & App Store”.
Finally, tap the toggle next to “Updates” to turn it on.
Your iPhone will now automatically update the apps that you currently have on your iPhone when updates for those apps are available in the App Store.
One thing to keep in mind with updating apps is that some app updates can use a significant amount of data when updating. To avoid using a lot of data on your cell phone data plan when updating apps, you can make sure that the “Use Cellular Data” option is toggled off. This way your apps will only update when you are connected to a WiFi network–which will not use any of your cell phone’s data plan.
