Ya,maybe is due to optimization problem to new Exynos processors. I played Tekken and Mobile Legends and is quite smooth.

Most likely this is the case. Snapdragon SOCs are more popular hence Adreno shaders for gaming are usually more optimized since development will be basing on it for small devs. Bigger company will have more capacity to handle all GPUs at launch. It will take a while but wont be that long before that developer optimize it for Mali gpus (used in Exynos)

Hey guys, what's your exynos chip binning?

I got G3D_5, poor battery life when gaming

according to xda, higher asv value, the better battery performance.

Press Vol Down + Bixby and ON to get into downloading mode to check the asv value.

Chip binning is related to how low the voltage supplied can go without CPU crash and how high can be overclocked without it crashing.

Never heard it is related to better battery performance at all since Samsung implemented DVFS in their core configuration and it will operate within tested safe values only, hence there's no phone is able to save significant juice compared to another without a custom kernel tweaked to get the best out of each bins and yields.

These were popular back in sgs1 and sgs2 where people theory craft and tune exynos chip kernel configs including downvolting to get god level battery life (usually for deep sleep mode) but the myth was debunked due to zero significant gains and many device suffer from SOD (sleep of death) since it can't get enough power to wake from deep sleep.

Yes, the higher the binning, the lower the power consumption to reach max speed 2.8ghz.

If your binning is lower, the higher power consumption for your gpu or cpu to reach the max speed.

This is the reason why lower binning cpu or gpu causing your poor battery life.

Partially correct.

Example, higher bin can do 2.8ghz at 1800mV while lower bin will do it at say 3200mV. However Samsung employed the same configuration for all devices that even the higher bin units will use same configuration as lower bins as well. This results in all almost same battery performance for production devices regardless of bins.

Only when you use custom kernel with voltage modification, you can force the device to use lower voltage at Max clockspeed for the particular core.

Huawei P20 Pro has 3x optical zoom and Lumia-styled lossless zoom at 40 MP. No OIS though on the main two cameras. But instead Huawei relies on what they called the Artificial Intelligence Stabilization (AIS). With 109 overall in Dxomark!!! These all in addition to a 4000 mAh battery and IP67 rating. Only thing it lacks is wireless charging. The Camera Reimagined dethroned. :-( Is it worth to jump ship?
