I like my smartphones vivid

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

How vivid does a cellphone have to be, although? Is preserving your cellphone at most brightness actually an issue? And what is the distinction between LCD and OLED? There are a selection of brightness-related particulars you need to know earlier than shopping for a cellphone, all of which I am going that will help you kind out in a rush.

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

Telephone brightness 101

When you may, in principle, price cellphone shows by way of lumens, you may nearly at all times see them gauged in nits. A single nit is equal to 1 candela (candlepower) per sq. meter. For a relative measure, take into account that the solar at midday is often claimed to provide 1.6 billion nits.

Your cellphone does not have to 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 quickly surge, although, every time a cellphone is outside or displaying HDR (excessive dynamic vary) content material. For example, 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 cellphone display screen wants. Most gadget makers are aiming for someplace between 1,000 and a pair of,000 nits for HDR features, and a pair of,000 nits or increased outside. My iPhone 16 Professional peaks at 2,000 exterior, and it is fairly readable even when the solar is thrashing down overhead.

Brighter is at all times higher, specs-wise, however something over 3,000 tends to be overkill, delivering diminishing returns. Not that that is stopped cellphone 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 might be turned on and off at will. The result’s an incredible distinction, with pure blacks, and highlights that do not bleed into surrounding objects. The format additionally tends to be extra energy environment friendly if you happen to select darker icons, wallpapers, and app settings.

LCDs (liquid crystal shows) generally have the higher hand, nevertheless. That is as a result of all LCDs rely on a number of backlights, which have a tendency to provide an total brighter picture, albeit on the expense of distinction. It is really inconceivable to realize true blacks with an LCD until it makes use of a number of backlights, and a picture space lined 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, a minimum of not but.

The distinction hole does permit 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 couple of telephones eradicate brightness from the specs debate fully through the use of e-ink. The pixels they use are fabricated from actual matter, so their visibility depends on exterior gentle sources, a lot in the identical approach you can’t learn a paper ebook in a pitch-black room. The built-in lamps you discover on e-ink units are literally frontlights, not backlights.

What it’s essential to learn about brightness settings

No must go full throttle

More often than not, it is best to keep away from ramping your cellphone as much as full brightness, irrespective of how spectacular it seems to be. 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 situations, leading to points like tearing (as in crying), blurring, dry eyes, and complications.

I do know from private expertise that at evening, 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 can go until I am not nervous about my alarm. My iPhone, in the meantime, is at all times put in StandBy mode, which in a single day each dims the show and tints it pink.

When pressure and sleep patterns aren’t points, there’s nonetheless the matter of battery life. A cellphone’s show is one in all 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 predominant changes a cellphone’s battery-saving/low-power mode makes.

Sometimes, the most effective compromise is to set your cellphone’s brightness as little as it can go whereas nonetheless being nice to have a look at. My iPhone 16 Professional is often set at round 50%, however you could must go increased or decrease than that relying in your gadget 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 outside excursions, like a visit to Disney World, or a yard Texas cookout with my in-laws. However even then, my iPhone often compensates sufficient robotically, making the thought moot.
