Samsung has just revealed another secret weapon of the Galaxy S21 Ultra

By now, most Samsung fans know that the Galaxy S21 Ultra is the only model out of the new flagship trio to support 120Hz at maximum display resolution. What nobody else besides Samsung Display knew until earlier this week is that the Galaxy S21 Ultra also has a new low-power OLED display, and for the time being, it's the only smartphone on the market to boast this new technology.

The new low-power OLED panel that debuted with the Galaxy S21 Ultra claims to deliver improved luminosity and power efficiency, but it's fundamentally the same as before. Instead of having a separate light source, OLED panels produce light when an electric current is sent through the panel's self-luminous organic materials. But what's different about the Galaxy S21 Ultra's new OLED panel is that — through processes unexplained — it allows electrons to flow faster and more easily across the display's organic layers.

The Galaxy S21 Ultra's low-power OLED is 16% more efficient

One of the most power-hungry components of a smartphone is the display and Samsung took it upon itself to improve the OLED formula as newer technologies such as 5G are leaving a bigger mark on battery life. Ultimately, what this new low-power OLED panel that was employed by the Galaxy S21 Ultra can achieve is a higher level of brightness and a reduction in power consumption of 16%.

We'll dive deeper into the topic of battery life in our upcoming Galaxy S21 Ultra review so stay tuned if you want to find out whether or not these improvements have paid off in real-life usage scenarios. But without spoiling any major details, battery life on the Galaxy S21 Ultra has left a good impression on us from day one, and perhaps this new low-power OLED panel is the reason why.
