Just when we thought that the Galaxy S20 series couldn't leak anymore, we now have another one that sheds some light about what we'll get out of the box. Based on previous leaks, we know that the base Galaxy S20 will come with a 4,000 mAh battery, the Galaxy S20+ with a 4,500 mAh cell and the Galaxy S20 Ultra with a 5,000 mAh unit. The first two will reportedly support wired charging at 25 W, while the Galaxy S20 Ultra can go as high as 45 W.

One of the most common techniques employed by manufacturers to nickel-and-dime users is to exclude a fast charger out of the box. Even the Galaxy Note 10+, which supports 45 W wired charging, came with a 25 W brick out of the box. Thankfully, the Galaxy S20 series will be better off. According to a Tweet by the prolific leaker, Roland Quandt, the Galaxy S20 and Galaxy S20+ will come with a 25 W charger out of the box, while the Galaxy S20 Ultra will come with a 45 W brick. Based on the experience with my personal Galaxy Note 10+, there isn't much of a difference between the two. It has saved me fifteen to twenty minutes at best, and the extra battery fatigue that comes with the higher wattage isn't really worth the time I save.
