I've been an iPhone user since day one and I just recently jumped ship to the S20 Ultra. So far I love it! I have noticed a small battery drain issue with it. It could be charged to 100% and taken off the charger and placed on my desk. Within a couple minutes of no usage, its down to 98% to 99%. Even on my desk overnight it will drain 5% or more with zero usage. I never had an issue with my iPhone and I've restored my S20 Ultra device a few times and I'm still seeing this battery drain. Is this common? Is it a non issue and something due to Samsung's design and regular power consumption?
