just got my new device the phone heatup whenever I WhatsApp and multitasking or gaming. when it heat up the battery drained like mad. I have no idea all the youtubers' reviews never discuss that, how can get 8 hours of screen time ? mine just 3 to 4 hours screen time max.
very disappointing will never buy exynos version. my s10+ is still lovely snapdragon version.
