4 Reasons Not to Install iOS 13.7 & 11 Reasons You Should

Apple’s iOS 13.7 update is a small milestone release, but it could have a huge impact on your iPhone’s performance. While some of you should install Apple’s new firmware right now, others are better off waiting for a few hours or a few more days before moving to the firmware.

Unlike most milestone updates, iOS 13.7 brings a very short list of changes to compatible iPhone models. It carries new features and under-the-hood improvements.

The iOS 13.7 update requires a fairly small download. It should be a little over 100 MB for iPhone owners moving devices from iOS 13.6.1 to iOS 13.7.

The iOS 13.7 download will be larger for those of you moving up from older versions of iOS. That’s because the features and fixes from the updates you skipped are baked into your upgrade.
