The OnePlus Nord 4 does one factor higher than another Android telephone

Other than a couple of deviations, OnePlus has a penchant for worth merchandise. The premium OnePlus 12 provides a (principally) superior set of options and a refined expertise over similarly-priced flagships such because the Galaxy S24 Plus or the Pixel 8 Pro. Similarly, the $500 OnePlus 12R provides distinctive efficiency and a flagship-like expertise for its worth. The OnePlus Nord 4, which sits in a worth bracket proper beneath the 12R, has its personal advantages, however one which stands out is its steel again.

The OnePlus Nord 4 is the primary and at the moment the only 5G phone to feature a metal back panel. Not solely is it a placing design however it additionally has one other trait that perceivably makes it extra thrilling than different telephones: Its steel physique doubtlessly helps enhance efficiency.

Metal is a greater conductor of warmth than glass or plastic and is superior at radiating warmth outward — which means the Nord 4 ought to run cooler than different telephones. The effectiveness at cooling can be anticipated to enrich the chipset driving the Nord 4 (the Snapdragon 7 Plus Gen 3). Despite being a sufferer of Qualcomm’s complicated naming, the Snapdragon 7 Plus Gen 3 is potent sufficient to run most demanding duties and is probably going geared to run AI functions sooner or later.

So, does the Nord 4’s steel again assist its Snapdragon chip run higher and cooler? I discovered.

How I examined Nord 4’s cooling

The largest perceived advantage of the steel again with regards to gaming. In addition to the vapor cooling chamber contained in the telephone, the steel again helps radiate inside warmth generated from the chipset or the battery — the 2 major sources of warmth contained in the telephone. I performed round (actually) with the OnePlus Nord 4 extensively to see if the speculation holds up in apply.

To consider the steel again’s results on the Nord 4’s efficiency, I got down to check how successfully it prevents warmth buildup contained in the physique. The analysis was divided into three elements, or potential contributors of warmth technology and trapping contained in the telephone. Other than gaming, I additionally examined difficult situations, corresponding to 4K video recording and high-speed charging, that may result in the telephone getting sizzling.

For every of those checks, I ran the duties for half-hour to let the warmth construct up contained in the physique and on the floor. After the completion of every job, I waited for the telephone to chill right down to the unique temperatures utilizing an infrared thermal camera and famous the time taken in every case. Here’s how the checks panned out.

Heating whereas 4K video recording

Video recording continually engages a number of elements, which, apart from the digicam itself, embrace the telephone’s chipset, storage, and picture sign processor (ISP). The show being continually engaged is but one more reason for the {hardware} to really feel burdened — and, due to this fact, warmth up in consequence. So, for my evaluation, I set the OnePlus Nord 4 to file a 4K video at 60 frames per second. The remainder of the settings, corresponding to white steadiness, had been left to computerized. Although the video was shot indoors, my canine contributed to some affordable movement capturing and, in consequence, occasional refocusing of the sensor.

The video was shot in an air-conditioned room, regardless of which the telephone’s exterior floor heated up considerably. After I ended the recording, I left the telephone to chill down. Here are my major findings:

• Ambient temperature: 82 levels Fahrenheit
• Starting temperature (earlier than video recording): 88 levels F
• Temperature after half-hour: 102 levels F
• Time taken to return to authentic temperature: 17 minutes

While the 17-minute span could appear harrowing, the heat subsided inside 5 minutes, and the telephone began to really feel chilly.

How cool is quick charging?

The Nord 4 expenses at 100W, which is commendably quick. Although the telephone expenses absolutely inside 35 to 40 minutes, that warrants some warmth technology within the course of. I adopted the same course of because the final time however with one key change. The telephone was charged and subsequently left to chill down with none air-con.

Here is what I discovered:

• Ambient temperature: 91 levels Fahrenheit
• Starting temperature: 95 levels F
• Temperature after half-hour: 104 levels F
• Time taken to return to authentic temperature: 28 minutes

It took longer to return to its authentic temperature (which nonetheless appeared harmful because of the heat room). However, to my shock, the nice and cozy room didn’t considerably decelerate charging as I assumed it will. Perhaps it will if the telephone reached temperatures within the vary of 120 levels or larger, which, fortunately, it didn’t.

This additionally goes on to again my preliminary speculation {that a} steel again would cool sooner in an air-conditioned room than one with out. But to substantiate my findings, I ran an in depth sequence of checks with variations to see how every impacts the Nord 4.

The Nord 4’s final check — gaming

Gaming is well one of the demanding duties for a telephone. Additionally, its propensity to warmth is certain to extend if the {hardware} struggles to maintain up with the calls for of the sport — and that’s what makes the Nord 4, a non-flagship telephone, the best candidate to check the results of heating.

For this sequence of checks, I ran one of many graphically heaviest cross-platform video games, Genshin Impact, on the Highest graphics settings with textures set to High and the meant body charge set to 60 fps. These settings make the perfect of {hardware} sweat, so testing how the Nord 4 holds up would have given us the insights we had been on the lookout for.

Besides turning to the best settings, I additionally used OnePlus’ personal HyperHDR function that upscales customary content material to HDR for higher visibility, particularly in darker scenes. But it additionally will increase the brightness and, due to this fact, calls for extra of the telephone’s {hardware}.

In addition to the temperatures, I recorded the Nord 4’s efficiency utilizing GameBench, knowledgeable game-benchmarking device. I have to disclose that whereas GameBench helped me with a free journalists’ license for the app’s Pro model, it didn’t have enter on my findings.

The check is subdivided into 4 elements, including one attribute at a time to assist consolidate the findings higher.

Part 1

The first one begins with me working Genshin Impact on the Nord 4 by way of its paces however in an air-conditioned ambiance. This would permit the telephone to chill successfully whereas I recreation after which depart the telephone to chill down. Here are my findings from the check:

• Ambient temperature: 82 levels Fahrenheit
• Starting temperature: 86 levels F
• Temperature after half-hour: 104 levels F
• Time taken to return to authentic temperature: 13 minutes

Interestingly, the telephone cooled extra successfully than it did within the case 4K recording check I ran above, additional solidifying my perception {that a} cooled setting can enhance its cooling. For more often than not, the telephone remained heat to the contact however by no means received uncomfortably sizzling. The inside temperature of the CPU, as per GameBench, stayed round 108 levels F, which doesn’t present a major distinction from the temperature on the exterior floor.

While enjoying, the sport constantly ran with none notable stutters. GameBench recognized it to ship a constant 57 frames per second over the course of half-hour, with the occasional body drops attributed to cooking meals, cutscenes whereas talking to unplayable characters, and loading screens.

Part 2

For the subsequent half, I examined with none exterior cooling. I performed the sport on the OnePlus Nord 4 whereas sitting in a room with out AC to see how sizzling the telephone will get.

As I famous in Part 1 of this check, the Nord 4’s exterior temperature pretty matches its inside temperature. So, I anticipated it to warmth up rather more with out releasing warmth as a result of sitting in a warmer room. But I used to be shocked when the telephone received considerably hotter than typical.

• Ambient temperature: 91 levels Fahrenheit
• Starting temperature: 96 levels F
• Temperature after half-hour: 113 levels F
• Time taken to return to authentic temperature: 25 minutes

About quarter-hour into the sport, the Nord 4 began to warmth up considerably. It reached a temperature that I would like my sizzling bathe to be at on a chilly day. While I may endure the warmth as a result of it was nonetheless in need of scalding, I would like to not comply. At the tip of the half-hour, I used to be glad it was over.

During a lot of the gameplay, the interior temperatures floated round 120 levels Fahrenheit, so the outward channeling was anticipated. With temperatures hovering so excessive, the Nord 4 additionally threw a warning whereas turning off the HyperHDR function. Findings from this half prompted me to vary yet another bit about this check.

Part 3

In this half, I performed the sport with out air-con however set the telephone to chill down in an air-conditioned room, assuming that if my concept was correct, it will assist the telephone cool sooner regardless of the upper temperature.

Once once more, the telephone received disadvantageously sizzling. But setting it down in a cooler room than used to play the sport actually helped velocity up the cooling course of. Here’s what I discovered:

• Starting ambient temperature: 91 levels Fahrenheit
• Cooling ambient temperature: 82 levels F
• Starting temperature: 96 levels F
• Temperature after half-hour: 113 levels F
• Time taken to return to authentic temperature: 10 minutes
• Time taken to return to chill down fully: 20 minutes

In the AC room, the Nord 4 returned to a cooler temperature 5 minutes sooner than the final check. In reality, it achieved its preliminary temperature in beneath 10 minutes, lastly returning to 88 levels in about 20 minutes of whole time.

By now, I used to be fairly satisfied my concept holds. But I couldn’t conclude with out one last check — involving supplies apart from glass.

Part 4

For the final and last a part of my gaming check, I roped in two extra telephones apart from the OnePlus Nord 4. The duo consists of the Realme GT 6, which comes with a plastic again and body made out of plastic. It runs the Snapdragon 8s Gen 3, a chip similar to the Nord 4’s Snapdragon 7 Plus Gen 3. Besides the Realme with a plastic again, I selected the OnePlus 12R with a glass again and steel facet body. Although the OnePlus 12R runs a extra highly effective Snapdragon 8 Gen 2 chip, I selected it for the dearth of a glass telephone with efficiency matching the opposite two. All of those telephones had been examined with air-con to examine how shortly every materials cools.

The following summarizes the findings from working the identical occasion of Genshin Impact on the three telephones:

The outcomes couldn’t be clearer and present a convincing image of the Nord 4’s potential to dissipate warmth higher than the opposite two units. The Realme GT 6, with a plastic again, retains essentially the most warmth internally and takes the longest to return to its authentic temperature. The OnePlus 12R understandably generated much less warmth internally because the extra highly effective chipset requires much less effort to realize the identical efficiency. However, it additionally traps a major quantity of warmth contained in the physique, taking solely barely much less time to chill down.

Had an exterior cooling supply been absent, we are able to think about the Nord 4 to really feel the most well liked whereas the opposite two units would lure extra warmth inside and throttle in consequence.

The Nord 4’s steel again actually works

While I admit the tactic I take advantage of above is just not sometimes the stuff from science labs and educational journals, it will get the purpose throughout pretty properly. It clearly conveys that steel helps efficient cooling of the smartphone, particularly when utilizing it for demanding duties corresponding to gaming.

The OnePlus Nord 4’s steel casing acts as a big radiator for the tiny CPU, and I can’t assist however draw a parallel with a PC that makes use of a passive cooler a lot larger than the CPU. Of course, an energetic cooling answer corresponding to a fan — both built-in or as an adjunct — would extremely amp up the cooling spree. Notably, whereas I attempted out the black version, the telephone’s colour might also affect its cooling. The No. 1 purpose why that will occur is as a result of black is healthier at radiating warmth to the environment than another colour. The second purpose applies extra particularly to the Nord 4, whose silver end has microscopic textures that give it a wave-like sample.

Meanwhile, warmth buildup inside different units can’t solely throttle efficiency but additionally threat the internals getting cooked, particularly in the event you are likely to overclock recreation settings on midrange telephones. This calls for simpler cooling options past the now plateauing vapor cooling chambers, and that is the place steel turns into efficient.

Simultaneously, there are drawbacks to steel constructions that we are able to’t ignore. Firstly, it will probably impede 5G alerts — regardless that OnePlus has seemingly discovered a treatment by chopping down the dimensions and upping the variety of antennas. Secondly, the telephone is certain to warmth up extra when used outside, within the solar, and this may be particularly tiresome whereas touring to hotter locations. Thirdly, it limits options corresponding to wi-fi charging and hinders features like MagSafe, which is why we could not see steel changing glass on dearer telephones.

For all it’s price, although, steel, coupled with more and more highly effective midrange chips, could be a breakthrough in telephone efficiency, as we see on the OnePlus Nord 4.
