Launched at the Mobile World Congress (MWC) 2018 last February, the Samsung Galaxy S9 has been well-received by the tech critics and regular users alike, due to its sophisticated new design and improvements over last year's S8. However, there might be one problem with the South Korean tech giant's latest flagship, which is poor battery capacity. The battery health problem particularly appears on the Galaxy S9 units powered by the Exynos 9810 processor, a recent test revealed.
As reported by Express UK, there might be a problem in Samsung Galaxy S9 units found in Europe, which are using the Exynos 9810 chipset. To note, the Galaxy S9 model distributed in North America uses Qualcomm's latest high-end mobile chip, the Snapdragon 845. In spite of the different processors used for the smartphone units, there are no expected disparity in terms of performance.
However, it appears that the Exynos 9810 chip is responsible for reduced battery life in the Samsung Galaxy S9. Per AnandTech, there is a huge difference in battery life between the Galaxy S9 model powered by Qualcomm SnapDragon 845 and those powered by Samsung's very-own Exynos creation. The test shows that the Snapdragon-powered S9 unit can last for 10.48 hours while browsing the web through Wi-Fi, while the Exynos unit can only last for 6.80 hours.
The Samsung Galaxy S9 and S9 Plus boasts 3,000mAh and 3,500mAh battery cells, respectively, which are the same battery capacities as their predecessors. However, the updated mobile chip may have been requiring more power from the battery, thus making the power reserve depleted more easily. In the case of Exynos 9810, the processor is said to have the worst battery test result among all others used in a Samsung Galaxy handset. In fact, the latest Exynos version has 3 hours less battery life than the Exynos 8895 used in the Galaxy S8.
Aside from the battery issue in the Exynos model of Samsung Galaxy S9, previous reports also point a problem on the smartphone's OLED touchscreen panel. There appears to be dead zones on the screen that do not respond to touch gestures, and Samsung is currently investigating on this matter.
