Samsung’s shiny new Galaxy S20, S20 Plus and S20 Ultra are stacked with new options like an improved digital camera that may document 8K video, a 120Hz show and 5G connectivity. There’s only one downside: All these instruments drain battery quicker and you might end up with battery life that does not stay as much as your expectations, particularly in case you’re upgrading from a Galaxy S10 or Note 10

That’s not completely surprising. For instance, our testing has shown that utilizing the 120Hz show setting on the Galaxy S20 can put a pressure in your battery as a result of it refreshes each pixel in your phone display 120 instances per second as a substitute of 60 instances a second.

I’ve been testing the S20 Plus for just a few days and have been capable of get via a full day with 120Hz activated, however the S20 Ultra didn’t fare as well in our review

My recommendation? Use the 120Hz possibility anyway. I discover that scrolling via Twitter is jitter-free and rapidly switching between apps simply feels quicker than with the usual 60Hz refresh fee that the majority telephones use. But when you have battery life points, swap again to 60Hz.
