I like my smartphones shiny

Display screen brightness is not typically trumpeted from the hills when Apple, Google, Samsung, or one other firm places out a brand new telephone. However after all, it is a type of particulars that is extraordinarily necessary in follow — a telephone with weak brightness may be onerous 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 authentic annoyance on lengthy roadtrips, since there was no approach it may compete with cloudless Texas skies.

How shiny does a telephone have to be, although? Is retaining your telephone at most brightness actually an issue? And what is the distinction between LCD and OLED? There are a variety of brightness-related particulars you must know earlier than shopping for a telephone, all of which I am going that can assist you type out in a rush.

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

Telephone brightness 101

When you may, in idea, fee telephone shows when it comes to lumens, you may virtually at all times see them gauged in nits. A single nit is equal to at least one candela (candlepower) per sq. meter. For a relative measure, take into account that the solar at midday is often claimed to supply 1.6 billion nits.

Your telephone would not have to be wherever close to that shiny to be readable, after all. Indoors, lower than 1,000 nits is ok, and even 500 nits tends to look fairly good. Peak brightness will briefly surge, although, every time a telephone is open air 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 telephone display screen wants. Most machine makers are aiming for someplace between 1,000 and a pair of,000 nits for HDR capabilities, and a pair of,000 nits or greater open air. 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 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 may 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 in the event 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 rely upon a number of backlights, which have a tendency to supply an total brighter picture, albeit on the expense of distinction. It is really unimaginable to realize true blacks with an LCD except it makes use of a number of backlights, and a picture space lined by a backlight occurs to be utterly devoid of element. That is why mini- and micro-LED had been invented — however you will not discover these applied sciences on any delivery smartphone, at the least 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 helps you to pick extra element. A 300-nit OLED panel can really feel roughly equal to a 500-nit LCD, although your mileage will differ.

A number 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 relies on exterior gentle sources, a lot in the identical approach which you could’t learn a paper e book in a pitch-black room. The built-in lamps you discover on e-ink units are literally frontlights, not backlights.

What it is advisable to 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, irrespective of how spectacular it appears. There are a number of causes for this — above all, your imaginative and prescient. Because the American Academy of Opthamology notes, full brightness can doubtlessly 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 evening, shiny shows can disrupt sleep. They typically make it tougher 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 is going to go except I am not anxious 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 purple.

When pressure and sleep patterns aren’t points, there’s nonetheless the matter of battery life. A telephone’s show is one in every of its most power-hungry parts, 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 major changes a telephone’s battery-saving/low-power mode makes.

Sometimes, one of the best compromise is to set your telephone’s brightness as little as it is going to go whereas nonetheless being nice to have a look at. My iPhone 16 Professional is often set at round 50%, however chances are you’ll must go greater or decrease than that relying in your machine 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 concept moot.
