Should I upgrade to iOS 26.4 Beta 3? Who should update immediately?

iOS 26.4 Beta 3 has fixed the error of full memory and app crashes, so this is a very worthwhile update for users to experience right now.

Apple has just officially launched iOS 26.4 Beta 3 with the main goal of “cleaning up” annoying errors remaining from the first test versions. Unlike Beta 1 and 2, which had many problems with temperature and memory, Beta 3 feels much smoother and more stable.

However, before deciding to upgrade, iPhone users need to ask themselves: is their device and work really suitable for a software version that is still in the completion stage? Let’s join Minh Tuan Mobile in analyzing target groups that should and should not update this version.

These groups of people should update to iOS 26.4 Beta 3 immediately

If you belong to one of the three groups below, iOS 26.4 Beta 3 is truly a “lifesaving” upgrade:

• Users who are on iOS 26.4 Beta 1 and Beta 2: This is an object that is required to upgrade. Beta 3 completely fixes the “System data” error taking up hundreds of GB of memory and common Gmail and Reddit application crash errors. Upgrading will help your phone get rid of extremely annoying lag and “virtual bloat”.

• Techies love to experience things early: With the arrival of features preparing for Siri 2.0 and Playlist Playground on Apple Music, those who love to explore new things will not want to miss this build. In particular, the search speed on the App Store has returned faster, making the app browsing experience much smoother.

• Users who own secondary devices: If you have an iPhone that you don’t use for work, installing Beta 3 is a great way to get familiar with the next generation of Apple Intelligence features before the official launch later this month.

The reason why iOS 26.4 Beta 3 is highly rated for its performance

Through practical tests, iOS 26.4 Beta 3 shows very good hardware optimization. Benchmark scores are stable at a high level (3,826 single-core points on the A19 Pro chip), but most importantly, the machine temperature always remains below the 33 degrees Celsius mark even when using heavy tasks. This shows that Apple has refined the power regulation system, helping the iPhone’s battery no longer be “exhausted” unreasonably like before.

Besides, fixing UI display errors and preparing the source code for the new Emoji set also shows the maturity of this operating system. Every swipe and touch operation on the ProMotion 120Hz screen now takes place smoothly and has instant response, bringing an extremely satisfying feeling to the user.

Who should patiently wait for the official release?

Although considered quite stable, iOS 26.4 Beta 3 is still not for everyone. If you belong to the following group, the advice is to continue to stay with the stable version of iOS 26.3:

• Users only have a single machine for work: Potentially small errors can still appear unexpectedly, affecting important banking or communication applications.

• Users appreciate absolute stability: Some errors with Shortcuts and Apple CarPlay are still reported sporadically. If you travel often and need a stable car connection, wait for the Release Candidate (RC).

• Users who do not have software handling skills: In case you encounter a serious error and want to downgrade to the old version, you will need a computer and certain technical knowledge. If you don’t want to waste time, be patient for another 1-2 weeks.
