Review iOS 18.4 beta 1 after 3 days of use

Detailed assessment of iOS 18.4 Beta 1 with improved battery life after 3 days, increasing performance and predicting the launch schedule Beta 2.

Apple has just released the iOS 18.4 Beta 1 version 1, bringing many notable changes to iPhone users. After more than 3 days of practical experience, this article will evaluate details about performance, battery life and points to note when updating to this new version on iPhone 14.

Battery life

In terms of battery life, iOS 18.4 Beta 1 initially has some problems but has improved significantly after a few days of use.

On the first day of using iOS 18.4 Beta 1, consumes about 90% of the battery and reaches nearly 7 hours of screen-on time. During this time, applications used mainly include watching Youtube Instagram, Safari. Compared to iOS 18.3, the first day battery life is somewhat inferior.

On the second day, with the use of about 70% of the battery, the battery life has improved significantly compared to the first day.

On the third day, with the same battery level as the second day (about 65-70%), the device reaches 6 hours 52 minutes Screen-on Time.

Note: The Beta 1 version still has battery drain phenomenon when not in use (standby). During sleep, the device still decreased by about 5% of the battery. This level is not too bad but still needs to be improved in the next updates.

Performance

The performance of iOS 18.4 Beta 1 is evaluated through the Geekbench application with three different tests during use.

The first test (right after installation)

In the first test, it was done immediately after installing iOS 18.4 Beta 1, a single multiplication point reached 2339 and a multi -core point reached 5562. This multi -core score is considered to be quite low compared to the previous version of iOS 18.3.1.

The second test (after one day)

After a day of use, when performing a second test, a single -core point increased to 2382 and multi -core points increased to 5937. This result showed that performance has been significantly improved compared to the first day.

The third test (after a few days)

At the third test after a few days of use, single -core points continued to increase slightly to 2376 and multi -core points reached 5815. Although the performance continues to improve, it has not reached the expected optimization level.

GPU performance

Regarding graphic processing performance, iOS 18.4 Beta 1 achieved the GPU ben score of 21271. This point is higher than the average and superior to the iOS 18.3.1 version, showing a marked improvement in graphic processing capacity.

Overall, the performance of iOS 18.4 Beta 1 is gradually improving over time. However, this is only the first beta version, so the optimal performance may be achieved in beta 2 or beta 3 versions.

Conclude

The battery life improves significantly after a few days of use, especially on Wednesday when the battery life reaches the best level despite using many battery consumption applications such as Tiktok and Netflix. GPU performance is better than the iOS 18.3.1 version, expressed through the benchmark score higher than the average level. For a first beta version, iOS 18.4 Beta 1 has an acceptable stability.

Despite many improvements, iOS 18.4 beta 1 still has battery drain when in the standby mode, with a reduction of about 5% during the time of use. Multi -core performance has not reached the optimal level as expected, although improved through each day of use. In addition, users can still encounter some small errors, this is the characteristic of the beta versions.

Recommend

For ordinary users, should wait for the official version or at least beta 2/beta 3 for a more stable experience. Technology enthusiasts can update to experience new features, but should pay attention to backup data and prepare for potential problems that may occur. Particularly for older iPhone users, should consider carefully before updating because performance may not be optimized on older devices.

iOS 18.4 Beta 1 is an positive step of Apple in improving the user experience, especially in terms of battery life. However, users should consider the actual needs and the importance of stability before deciding to update.
