Samsung S22 S21 One UI 5.1

In February 2022, Samsung introduced the Galaxy S22 series smartphones. These premium Galaxy devices feature Snapdragon 8 Gen 1 (widely) or Exynos 2200 (Europe) chipsets. In software department, the lineup is running Android 13 (One UI 5.0), up from pre-installed Android 12 (One UI 4.1).

On February 1st, the company is going to unveil the Galaxy S23 series, which runs Android 13-based One UI 5.1 out of the box. In near future, the company will share the S23 lineup’s exclusive One UI 5.1 with its older flagship devices through software updates.

Features apart, the Galaxy S22, S22 Plus and S22 Ultra users are facing different kinds of issues (via PiunikaWeb) with their smartphones such as battery drain, heating and low power efficiency. Users believe that the situation was better before December 2022 patch, which got worse with January 2023 patch.

Among consumers, there are discussions that the battery drain and heating issues are generated on models due to chipset maker differences as well as Samsung Foundry. The Exynos 2200 and Snapdragon 8 Gen 1 processors are manufactured by Samsung foundry.

Due to inefficient processes, the system on chip gets affected by battery consumption issues due to thermal management. Since consumers in some countries such as India are quite satisfied with their Galaxy S22 phone’s battery, the issue is mainly reported spotted on Exynos models.

During Exynos 2200’s internal testing, Samsung faced critical thermal throttling due to chipset’s inefficiency and additionally powerful GPU, which forced it to reduce clock speed by 0.61Ghz. To bring the world’s most powerful GPU, Samsung partnered with AMD and used Xclipse GPU in the Exynos 2200.

Due to Exynos’ heating and Foundry’s production efficiency issues, Samsung turned to Qualcomm and decided to ditch its self-developed SoC from the Galaxy S lineup. This year, the Galaxy S23 series uses Snapdragon 8 Gen 2 chipset manufactured by TSMC, worldwide.

We hope Samsung will soon fix battery draining and heating issues on the Galaxy S22 devices through firmware update. Since hardware issues can’t be fixed with even hundreds of firmware updates, they could be reduced or optimized with code changes.
