Samsung Galaxy S8 charging issues

Here we go again, another feature seems to be missing and Samsung is not telling us. Last week, we talked about the absence of UFS 2.1 on Galaxy S8 with Snapdragon 835 chipset. Now, another issue emerges when Phandroid published an article about Samsung Adaptive Fast Charge which according to them doesn’t work when the screen is on.

As we all know, Samsung Adaptive Fast Charge is just another name for Qualcomm Quick Charge 2.0 for Exynos models. It is the same technology found on Galaxy S7 and S7 Edge. According to Phandroid, Qualcomm Quick Charge 2.0 will only work when the screen is off, but this limitation has since been fixed with the latest Quick Charge 4.0 found in Galaxy S8 models powered by Snapdragon 835.

According to Phandroid, it takes about three hours to fully charge the S8 when you’re using it despite the device giving the usual “fast charging” notification. Here’s the result of their testing:
