Today morning experienced the heat and the phone started becoming very laggy. Was doing a few internet banking transactions that due to the lag took 25mins. In that 25 mins, battery dropped from 96% to 83%, in the end let the phone cool down before I resumed my transactions. Tensor G3 from Exynos foundry also cannot make it. Hopefully the Tensor G4 will be made in the TSMC foundry as rumours mentioned.
After so many years and generations of Exynos SOCs, still so poor in power efficiency and heat management. 5000mah also no use. Samsung better just stick to making phones and electrical appliances.
