The battery is great but the app still has errors

iOS 26.4 Beta 2 has just been released 24 hours ago, helping to improve battery life compared to the old version but still encountering Gmail application crash errors, users need to pay attention.

After just one day of release, iOS 26.4 Beta 2 has created a wave of heated discussion in the technology-loving community. For those who were disappointed with the battery life on Beta 1, this version is truly a surprising gift.

However, like every other test version, Apple is still facing the problem of application stability when some popular names start to show annoying crashes. Let’s dive into the actual experience with Minh Tuan Mobile after 24 hours of use to see if this is the right time for you to press the update button.

iOS 26.4 Beta 2 battery life: Impressive leap

The biggest and most surprising plus point on Beta 2 is the power management ability. Through high-intensity practical use tests, the device consumes about 79% of the battery but provides more than 7 hours and 39 minutes of continuous use (On-screen).

If we compare directly with the previous Beta 1 when users only received about 5 hours of use for the same amount of capacity consumption, we can see that Apple has optimized the background processes extremely well.

With this result, iPhone users can fully expect an “unparalleled” battery life when the official version is released next month.

If you are looking for the latest iPhone models to enjoy the durable battery life of iOS 26.4, don’t miss the bargain list at Minh Tuan Mobile:

Actual performance and sudden application crashes

Although the overall touch and swipe experience still maintains the characteristic smoothness of iOS 26, the Beta 2 version has begun to exhibit application compatibility errors.

Reality records show that two popular applications, Gmail and Reddit, often encounter stalls during use.

This is a pretty big minus point for users who regularly handle work via email or need absolute stability for daily social networking applications. This situation may be fixed in application updates from the developer or in the upcoming Beta 3.

Geekbench score: Slow start but strong breakthrough

Regarding processing power, Benchmark tests on iOS 26.4 Beta 2 show a quite interesting scenario. During the first test run immediately after the update, the CPU score (especially multi-core) was unusually low, indicating that the system needed time to rearrange resources.

However, after just a few hours of stability, the results exploded again with 3455 single-core points and 8764 multi-core points, surpassing the average of previous versions. In particular, graphics performance (GPU) recorded extremely high scores, promising to bring extremely impressive gaming and AI video processing experiences to professional users.

Summary: Choice for users who like to experience

In short, iOS 26.4 Beta 2 is a very encouraging update in terms of energy, dispelling the worries of Apple fans quickly losing battery power. However, because there are still crashes in the Gmail and Reddit applications, users who prioritize stability for their work should patiently wait a little longer. On the contrary, if you are a “Power User” who loves to dabble in technology and needs a durable battery to use all day long, this Beta 2 is completely worthy for you to experience right now.
