Play PUBG smoothly, without overheating!

Evaluating iOS 26.2 on iPhone 12 shows smooth PUBG gaming performance at high graphics, good heat control even though there is still slight lag.

While the user community is paying attention to new iPhone lines, the iPhone 12 is still silently proving its durability with the iOS 26.2 update.

After the actual testing process including boot speed test, Benchmark score and experience with the heavy game PUBG Mobile, iPhone 12 showed very commendable results, confirming that Apple still optimizes very well for older devices.

If you want to experience the smoothest iOS 26.2 features, upgrade your device:

Impressive boot speed and benchmark scores

Starting with the boot test, the iPhone 12 running iOS 26.2 only takes about 15 seconds to complete the boot process and be ready for use. Immediately after entering the main screen, the device operates quite smoothly, although sometimes there is a slight stutter when pulling down the Control Center bar for the first time, but after that everything becomes much smoother.

In terms of technical scores, Geekbench tests show the clear superiority of the iPhone 12 compared to its predecessor, the iPhone 11. The Metal GPU score of the iPhone 12 reached more than 16,000 points, while the iPhone 11 only stopped at 13,000 points.

This difference truly reflects the hardware power that Apple has equipped for the 12 series, ensuring the ability to handle heavy graphics tasks well even when running on the latest operating system in 2025.

Experience the PUBG Mobile game: Top graphics, stable temperature

The biggest highlight in this review lies in the gaming ability. The PUBG Mobile game on iPhone 12 running iOS 26.2 allows very high graphics settings.

Users can unlock “Extreme” frame rates even with HDR graphics enabled. Even the Ultra HDR option has appeared, delivering sharp image quality and surprisingly realistic shadow details.

During actual gameplay, iPhone 12 handles combat phases quite smoothly. However, due to hardware limitations, the device sometimes still experiences slight frame drops in overload situations, but it does not affect the overall experience too much. The most commendable thing is the ability to control temperature (Thermals).

Even when playing at high settings, the device only warms up slightly and maintains a stable temperature throughout play, without overheating, leading to screen brightness reduction or sudden application shutdown.

Conclusion: The stable update is worth the upgrade

To summarize, iOS 26.2 on iPhone 12 is a very “clean” and stable update. It not only keeps the 5-year-old phone running smoothly but also exploits the hardware’s power to meet high-end entertainment needs. The device’s dual speaker system (Stereo speakers) still provides loud, clear and vivid sound quality, contributing to enhancing the gaming experience.

If you are using an iPhone 12 and wondering whether to upgrade to iOS 26.2 or not, the answer is YES. Although the battery may drain a little faster when playing heavy games (understandable with older machines), the stability and excellent temperature control of this version will definitely satisfy you.
