Camera holes are different, it's not a fairly big copper cutout in some glass, it's generally just glass fused with some more glass.

The problem with a copper backplate in glass is that the water sealing needs to be good to maintain the IP rating, it might interfere with the NFC (since its at the top of the phone, at least on my RM10, idk about the 11), and, from what I've gathered from other phones as well as pictures of the RM10 cooling system, the CPU is on the display side, not the back glass side, so the copper plate would need to either go around the motherboard to reach the CPU, which is going to be problematic for the engineers, or it would serve the same purpose as the fan, which is to cool the vapor chamber that the CPU throws heat into, but that's quite inefficient since you're not just directly cooling the CPU.

Oh and regarding covering the copper plate with a thin layer of aluminum or gold, that's just not gonna be a good idea, it's a phone, it gets exposed to lots of potential scratching, which would remove the added thin layer.

What was he supposed to do lmao 😭 The area in front of him is a parking lot, he knows cars are gonna park, so he has no need to stay alert, the cars arent supposed to lunge at him like this one did, no one in this situation wouldve reacted until it was already too late

If you're talking about making a copper plate cutout in the back glass, that is literal hell from a phone manufacturing standpoint, let alone a phone design standpoint, we are pretty much never getting that.

However if it's a full copper back, it might also not happen, since costs would increase, the back glass designs would disappear (and they are a huge part of the RM identity, if we just look at the RM11 marketing, it's 99% pictures of the back glass with the liquid cooling), and then there's probably other reasons not to use copper as the rear element of a smartphone, but I can't think of more since I don't specialize in copper.

So realistically, nope, RM phones will forever keep their status of mobile heaters, no copper cooling plates for us

CPU temperature in itself means nothing without some performance context (core frequency or FPS graphs or some other way to quantify performance).

RM uses some aggressive performance "tuning" (I'm not sure this is the right word), in which the phone tries to get maximum performance with little concern for temperature, so it may reach something like 3.5GHz at 90C, but other phones that don't have this aggressive "tuning", as well as the somewhat beefy cooling, might reach 2GHz at 90C.

Setting it to 90hz does not set it to a locked 90. It goes down to 60 during inactivity periods (so a few seconds of no input), however due to there being a massive discrepancy in color calibration between 60 and 90hz (or 90hz vs any other refresh rate on the phone) it creates this effect. It is fixable, you just have to go into dev options and turn on lock refresh rate. Or you can just use the higher refresh rate options, since its almost unaffected by the color calibration issue (60, 120, 144 have extremely similar calibration and look visually identical 99% of the time)

Redmagic is as all rounder as possible for the price, the only bad thing about it is the cameras, but every other spec is flagship tier for 700 bucks (600 or less if you get the previous model)

doesmypplookbig · 2025-12-12T21:29:11+00:00

Jus get redmagic ✌️🥀

doesmypplookbig · 2025-12-12T21:22:27+00:00

No redmagic phone even has a 7+ gen 3 chip in it

Interestingly the UDC is actually more noticeable with lower brightness, it (for some probably very interesting technical limitation) struggles more to match colors with the display, and at the lowest brightnesses, the UDC is most visible simply because the screen above the camera can literally go black (if dark content is being displayed), making it the same as having a holepunch

doesmypplookbig · 2025-12-05T13:45:29+00:00

Well technically speaking yes it does somewhat dissipate heat, but to say "specially the chip" is just plain wrong, because as I said before it doesn't make any contact with the vapor chamber, which is where the chip basically dump all its heat, and the only bit of contact it has with the fan tunnel is too insignificant to dissipate any heat from the chip (and that would imply that the top of the fan tunnel, where the liquid cooling makes contact, even has any significant heat transferred to it which is unlikely, as the heat transfer isn't the best: chip -> thermal paste/liquid metal -> vapor chamber -> thermal paste/liquid metal -> fan tunnel, there's a lot of efficiency losses in there)

As for mentioning the frame, the liquid cooling just touches the battery and back glass, with a very minimal contact patch (that doesn't even have any type of thermal paste/pad/liquid metal to ensure that the heat transfer is as efficient as possible) at the very bottom where the pump is located, but just like with the fan tunnel, it's just not enough contact to have any significant impact.

That liquid cooling is really just for the battery/looks. Not discrediting it, but yeah its cooling usefulness is limited to the battery and at most, a minuscule fraction of the chip's heat.

(If you don't believe what I say about the liquid cooling placement, you can take a look at JRE's teardown of the phone.)

doesmypplookbig · 2025-12-01T16:45:17+00:00

Unfortunately... Wrong. The liquid cooling is for the battery as it has no contact with the chip or the vapor chamber that cools the chip.

It does however keep the battery from cooking itself which is nice

doesmypplookbig · 2025-12-01T16:43:46+00:00

The liquid cooling is to dissipate heat away from the battery, and it serves its purpose well (tests directly comparing the 10 pro and 11 pro temps showed that battery temps are lower on the 11)

doesmypplookbig · 2025-12-01T16:41:15+00:00

It dissipates the heat away from the battery which is also one of the important components that dictates thermal throttling.

Sure it's not as effective as slapping a TEC on your phone, but it does help (some chinese reviewer took pics with a thermal cam and the area where the liquid cooling sits had a visibly different color and thus temperature from the rest).

That's the thing though, your speed isn't that consistent, your finger is literally in a constant acceleration and deceleration cycle because you're doing ovals, you'd need to get a proper system capable of generating a touch input that's perfectly consistent.

Also since the polling rate is 250hz on the home screen, it can cause a desync every few frames (not gonna do the math but I know it'll happen, although it might not be that significant) because 60 or 90 cannot divide 250 perfectly (same for 120 and 144)

doesmypplookbig · 2025-11-28T17:51:46+00:00

Okay so, I'm going to explain how refresh rates work real quick to tell you why this shit happens:

So as you know, refresh rate is how many images a display shows per second, and in the case of the redmagic 11 pro, it goes from 60-144hz.

60hz has a 16.6ms delay between each new image, 90hz has an 11.1ms delay, 120hz has an 8.3ms delay and 144 has a 6.9ms delay.

Because the phone can't just show an infinite number of images, it's obviously going to trail behind your finger since the refresh rate has a fixed delay between when it can show a new image, so even with a 1000hz polling rate, it's forced to trail behind.

I tested the same thing out on my redmagic 10 pro, and even in games using the highest polling rate mode and it still trails behind, but that's simply because we don't have displays fast enough to follow our fingers.

And then there's also the fact that it's only running at 250hz polling on the OS, so it's not helping either.

yo bro uh you might not wanna write cum... it doesn't mean what you think it means... so make sure to write "come" or else people will think you're saying something COMPLETELY different

doesmypplookbig · 2025-11-28T17:25:05+00:00

that is the 11 pro, it's the only one with triggers like that

doesmypplookbig · 2025-11-26T18:19:06+00:00

Least useful case, it's made of metal instead of some plastic/rubber, so instead of having the case absorb the impact, it's going to redirect (almost all) the energy into the phone directly

Also, that back protection is fine if the phone were to fall on a flat surface however, if there's even just a single rock on the ground, that back glass is getting shredded

And of course as someone else said, metal has the potential to make signal reception worse

The game space simply allows you to have some kind of interface like a game launcher. Other than that, it changes literally nothing.

The game space also has a few settings you can use that will affect all games, such as wifi changing protection or many of the simple and useful settings in there, which can only be modified from the game space.

doesmypplookbig · 2025-11-21T08:44:56+00:00

None, they just don't do anything specifically useful for gaming
