This means LCD screens are constantly drawing power, regardless of the colors being displayed.
In summary, AMOLED screens often offer better battery life compared to LCDs because they only power the necessary pixels. Dark mode is a huge win for AMOLED phones, extending battery life significantly. Consider the display technology when choosing your next phone if battery longevity is a priority.
Real-World Battery Experiences with AMOLED
I remember upgrading to my first phone with an AMOLED display. Before that, I was constantly hunting for outlets, especially during long travel days. It felt like my phone was always on the verge of dying. The difference with the AMOLED screen was immediately noticeable. I could finally get through a full day without the dreaded low-battery anxiety. One time, I was on a camping trip, and I forgot my portable charger. Everyone else's phones were dead by evening, but mine still had juice left the next morning, thanks to the AMOLED screen and my strategic use of dark mode. AMOLED technology creates vibrant colors and deep blacks by using individual pixels that emit their own light. Because each pixel is self-lit, the display only uses power for the lit pixels and uses very little to no power when displaying black. On the other hand, LCDs use a backlight to light up the entire display, meaning it’s using power constantly. This backlight is always on, even when displaying black. The difference in how these screens are lit is the main reason for the power saving of AMOLED screens. The contrast ratio is also much better on AMOLED screens, which leads to a better viewing experience and also helps save power. When using dark mode, the pixels displaying black are turned off, saving battery and reducing eye strain.
How AMOLED Saves Battery
AMOLED screens save battery primarily because of how they create light. Unlike LCD screens that rely on a backlight shining through a liquid crystal layer, AMOLED screens use organic compounds that emit light when electricity is applied. The crucial difference lies in the fact that individual pixels can be turned off completely. This means that when displaying black, an AMOLED screen consumes virtually no power in those areas. LCD screens, on the other hand, always have the backlight on, even when displaying black, which consumes power. Think of it like having individual light bulbs versus a single floodlight. Turning off unused bulbs saves energy, while keeping the floodlight on consumes energy regardless of how much light is needed. The power savings become particularly noticeable when using dark mode or themes with predominantly black backgrounds on an AMOLED screen. In these scenarios, the screen is essentially turning off large portions of its display, resulting in significant battery life improvements. Furthermore, the colors are more vibrant and the blacks are deeper, making for a better viewing experience that also conserves power. AMOLED displays are efficient not only in their individual pixel management, but also in their dynamic range, meaning they can display a wide range of brightness levels while optimizing energy usage. For example, an image with a lot of dark tones won't require the screen to push all the pixels to their maximum brightness, which would be much more power intensive.
