I like my smartphones vivid

Display brightness is not usually trumpeted from the hills when Apple, Google, Samsung, or one other firm places out a brand new telephone. However after all, it is a kind of particulars that is extraordinarily vital in observe — a telephone with weak brightness will be exhausting to make use of indoors typically, by no means thoughts stepping out into the tough noon glare. After I was dwelling in Austin, a dim telephone was a official annoyance on lengthy roadtrips, since there was no method it might compete with cloudless Texas skies.

How vivid does a telephone must be, although? Is conserving your telephone at most brightness actually an issue? And what is the distinction between LCD and OLED? There are a selection of brightness-related particulars it’s best to know earlier than shopping for a telephone, all of which I am going that will help you type out in a rush.

How brightness is measured, and the way a lot is sufficient

Telephone brightness 101

When you might, in principle, charge telephone shows by way of lumens, you will nearly all the time see them gauged in nits. A single nit is equal to 1 candela (candlepower) per sq. meter. For a relative measure, think about that the solar at midday is normally claimed to supply 1.6 billion nits.

Your telephone does not must be anyplace close to that vivid to be readable, after all. Indoors, lower than 1,000 nits is okay, and even 500 nits tends to look fairly good. Peak brightness will briefly surge, although, every time a telephone is outdoor or displaying HDR (excessive dynamic vary) content material. For instance, the Pixel 9 Pro can hit 2,000 nits when displaying HDR video, and three,000 nits at its absolute brightest.

That ought to provide you with a way of how a lot energy a contemporary telephone display screen wants. Most system makers are aiming for someplace between 1,000 and a couple of,000 nits for HDR features, and a couple of,000 nits or increased outdoor. My iPhone 16 Professional peaks at 2,000 outdoors, and it is fairly readable even when the solar is thrashing down overhead.

Brighter is all the time higher, specs-wise, however something over 3,000 tends to be overkill, delivering diminishing returns. Not that that is stopped telephone makers — some Chinese language fashions are able to 4,000 nits or extra. In March 2025, Samsung demonstrated an OLED panel able to 5,000 nits.

LCD vs OLED vs different requirements

For as soon as, older tech wins

Most telephones now use some type of OLED show, an acronym standing for natural light-emitting diode. As a rule, it is the superior expertise, since particular person pixels will be turned on and off at will. The result’s a tremendous distinction, with pure blacks, and highlights that do not bleed into surrounding objects. The format additionally tends to be extra energy environment friendly when you select darker icons, wallpapers, and app settings.

LCDs (liquid crystal shows) typically have the higher hand, nonetheless. That is as a result of all LCDs depend upon a number of backlights, which have a tendency to supply an general brighter picture, albeit on the expense of distinction. It is really unattainable to realize true blacks with an LCD until it makes use of a number of backlights, and a picture space coated by a backlight occurs to be fully devoid of element. That is why mini- and micro-LED had been invented — however you will not discover these applied sciences on any transport smartphone, not less than not but.

The distinction hole does enable OLEDs to punch above their weight in uncooked nits. It is a query of perceived brightness — since each highlights and shadows are starker, OLED enables you to select extra element. A 300-nit OLED panel can really feel roughly equal to a 500-nit LCD, although your mileage will fluctuate.

A number of telephones remove brightness from the specs debate completely through the use of e-ink. The pixels they use are made from actual matter, so their visibility relies on exterior mild sources, a lot in the identical method you could’t learn a paper guide in a pitch-black room. The built-in lamps you discover on e-ink gadgets are literally frontlights, not backlights.

What you could find out about brightness settings

No must go full throttle

Apple / Pocket-lint

More often than not, it is best to keep away from ramping your telephone as much as full brightness, regardless of how spectacular it appears. There are just a few causes for this — above all, your imaginative and prescient. Because the American Academy of Opthamology notes, full brightness can probably create pressure in some eventualities, leading to points like tearing (as in crying), blurring, dry eyes, and complications.

I do know from private expertise that at night time, vivid shows can disrupt sleep. They usually make it more durable to get to sleep within the first place, and within the center hours, lights can shine straight by way of your eyelids and wake you up. I do watch YouTube on a Nest Hub at bedtime — however its brightness is cranked as little as it should go until I am not anxious about my alarm. My iPhone, in the meantime, is all the time put in StandBy mode, which in a single day each dims the show and tints it crimson.

When pressure and sleep patterns aren’t points, there’s nonetheless the matter of battery life. A telephone’s show is certainly one of its most power-hungry elements, rivaled solely by its processor and wi-fi radios. The upper a display screen’s brightness is, the extra energy it consumes, draining your battery. Certainly, that is one of many fundamental changes a telephone’s battery-saving/low-power mode makes.

Usually, the most effective compromise is to set your telephone’s brightness as little as it should go whereas nonetheless being nice to have a look at. My iPhone 16 Professional is normally set at round 50%, however you could must go increased or decrease than that relying in your system and preferences. Even dropping to 80% ought to make a significant distinction.

Does full brightness ever make sense? Personally, I have a tendency to order that for the sunniest of out of doors excursions, like a visit to Disney World, or a yard Texas cookout with my in-laws. However even then, my iPhone normally compensates sufficient robotically, making the concept moot.
