It is a well-established fact that the level of battery consumption that takes place in any electronic device is directly correlated to the number of activities and processes that are taking place inside it. This raises a notion that how fast or slow one device use energy could vary significantly to another, depending on that factor alone.
When you consider that display resolution is a key factor in differentiating one smartphone to another, it only begs the question as to whether or not such feature negatively affects the device’s battery life.
The question does indeed make sense considering the fact that higher resolutions meant more pixels-per-inch (PPI), in such a way that a 1440p (3040×1440) resolution contains more PPI than a 1080p (2340×1080) does. But does using a higher resolution equate to higher power usage, therefore taking more toll to our gadgets’s battery charge?
In a bid to answer this theoretical question, PhoneBuff conducted a video experiment showing a side-by-side comparison between two identical Samsung Galaxy S10+ units. The only difference between the two is its screen resolution — 1440p and 1080p, respectively.
If you happen to not have the privilege of sparing 5 minutes of your time to see the video from start to finish, here is the key takeaway — there is no difference at all.
The idea is quite surprising, especially under the notion that running a phone on 1440p versus running another in 1080p showed sluggishness on the former which likely hints of a more intensive process on the device. With more internal processing comes more energy demand, right?
Apparently, that is indeed not the case as what the video had shown.
Right at this point, the only significant impact of a high resolution like 4K on a mobile device applies on performance in exchange of “better” visuals from the otherwise upscaled lower resolution like 1080p.
