Is it worth upgrading now?

The iOS 26.4 update officially fixes keyboard errors and brings stable battery life after 24 hours of real-world experience for current iPhone users.

iPhone users over the past time must have been tired of the keyboard responding slowly or the battery draining “unpredictably” on test versions. The biggest question right now is whether the officially released iOS 26.4 version can really solve those “pains” to bring us a truly smooth experience?

The answer is iOS 26.4 is considered the most valuable and stable update from the beginning of 2026. If you need an iPhone with durable battery, cool device and accurate typing, this is the golden time to upgrade immediately.

To prepare for the most groundbreaking AI features on the smooth iOS 26.4 platform, everyone should immediately refer to the list of iPhone 17 Series at extremely bargain prices at Minh Tuan Mobile:

Actual battery life is surprising: Nearly 8 hours of use with only 75% battery

One of the most concerning numbers is energy consumption. In a practical test with the iPhone 16 after the first day of the update, the device used about 75% of the battery capacity, bringing nearly 8 hours of On-screen (SOT).

Tasks include watching YouTube, surfing social networks, and general communication via WhatsApp. This is a fairly stable result for the first day, when the machine still has to run data rearrangement processes in the background.

In fact, the device does not experience abnormal heating when running common applications. However, users also need to note that every iOS update takes 2 to 3 days for the battery to really get into the most stable orbit.

If you’re on version 26.3.1 and feel satisfied with the battery, iOS 26.4 won’t disappoint you, but it’s unlikely to make a huge leap in usage time.

Smooth real-world performance and solutions to classic keyboard errors

Regarding processing power, the multi-core CPU score recorded after a few hours of installation reached more than 8,700 points on Geekbench 6. Although not a record score compared to the Beta versions, the smoothness of daily swipe operations has been significantly improved.

Most notably, the once annoying keyboard sensitivity error has been handled quite well by Apple. The typing experience is now more responsive, with less stuttering or mistyping characters when performing quick operations.

Graphics processing capacity (GPU) also remains at a high level, ensuring applications that require graphics or AI-enabled features operate smoothly. The cooling system works effectively, keeping the device only slightly warm during the Benchmark process, showing that Apple’s resource coordination algorithm has reached a certain maturity.

This is a good sign for users who need a stable device for high-intensity work without worrying about sudden performance drops.

iOS 27 roadmap and preparation for the future Apple Intelligence

Along with the launch of iOS 26.4, Apple has also officially confirmed that the WWDC 2026 event will take place from June 8. This will be where the iOS 27 operating system is unveiled with a focus on absolute stability and smarter Siri 2.0.

Many experts expect that even older models such as iPhone 12 or even iPhone 11 will still be supported with upgrades to enjoy these software improvements.

Apple’s continuous tweaking of small patches like iOS 26.4 shows that the company is putting all its effort into perfecting the user experience before entering a new hardware cycle.

Currently, the stock of iPhone 17 and iPhone 17e at Minh Tuan Mobile system is very abundant, ready to support customers in upgrading to genuine devices to fully enjoy the latest AI features on iOS 26.4.
