An earlier statement from a tipster claimed that the Galaxy Note 20 series won’t support the 120Hz refresh rate at the highest resolution, which would have disappointed most people planning to make a purchase. However, the upcoming models should be able to deliver better battery life thanks to dynamically switching between refresh rate values. According to a tipster, Samsung will be bringing this option when it readies its flagship smartphone models.

This feature is present on some apps when using any Galaxy S20 model, so it’s expected to bring the same battery life improvements for the Galaxy Note 20. According to previous reports, only the Galaxy Note 20 Ultra will support the 120Hz refresh rate, so we’re assuming that this model will also support dynamic switching of refresh rates based on what’s being shown on the display.
