Battery lasts nearly 8 hours, app errors fixed

iOS 26.4 Beta 3 brings impressive battery life of nearly 8 hours of use along with a series of Gmail patches and important notifications for iPhone.

The iOS 26.4 Beta 3 update appeared right at the time Apple was refreshing the iPad and MacBook product range, showing the “Apple House”‘s efforts in synchronizing software and hardware.

After exactly one day of practical experience, the first impressions of this version are extremely positive. Although the system usually takes a few days to fully stabilize, what Beta 3 shows from the first 24 hours is enough to make users feel satisfied, especially in terms of power management and smoothness of the interface.

Actual battery life: Nearly 8 hours of use with only 81% battery

The most impressive point in this review is the battery. Through practical tests with high intensity usage, the device only consumes about 81% of the capacity but delivers up to 7 hours and 40 minutes of On-screen (SOT).

Test tasks include watching YouTube content for over 2 hours, scrolling through TikTok, Instagram, and Threads continuously. This is an extremely promising number, showing that Apple has fine-tuned the background processes of the artificial intelligence toolkit very well.

If fully charged to 100%, users can completely confidently use the device all day long with more than 10 hours onscreen without the need for a backup charger.

Smooth performance but graphics score is still “unknown”

In terms of touch experience, iOS 26.4 Beta 3 feels extremely agile. The response speed when opening an application or searching on the App Store is almost instantaneous, giving the feeling that the device is more powerful than the Beta 2 version.

However, a rather strange point is that the CPU scoring results using Geekbench are not really as explosive as they actually feel. The current single-core and multi-core scores are only decent, suggesting that Apple may be prioritizing stability and temperature control rather than pushing clock speeds to the maximum.

Notably, the graphics scoring feature (GPU Benchmark) is currently having compatibility problems on this Beta 3 version. Reality records show that the grading application often crashes while taking the test.

Although this error does not affect daily use experiences such as playing games or watching videos, it shows that Apple still needs further Beta versions to fully optimize intensive graphics processing capabilities.

Fix a series of frustrating bugs: From notifications to Gmail applications

The best news for users is that the long list of annoying errors has been completely fixed. First is the notification display error and the lock screen works perfectly, no longer crashes or displays in the wrong position.

Next, the “classic” error on the Gmail application that caused the device to freeze when replying to emails has completely disappeared. The App Library has also been neatly rearranged, fixing the problem of incorrectly displayed folders that caused a lot of trouble in the old version.

In short, iOS 26.4 Beta 3 is a very valuable upgrade, providing the necessary stability before moving to the official version. If you are experiencing battery problems or app crashes in Beta 2, updating to Beta 3 right now is the absolutely right decision. For common users, the stability of this version is also a good sign that the official iOS 26.4 is very close.
