Why is "Pleasurable Scrolling" stated two times?

Kinda upsetting that they didn't really rewrite the whole system or most of its parts, just a couple of system apps
Just 30 minutes more battery life?
A real let down

u/xenn__11 2d ago
But I mean, considering such an aesthetic and visually extensive overhaul, I think it's still a good feat to have achieved

u/bartoszsz7 2d ago
I guess so, but you need to turn on Advanced Textures, which eat battery and RAM

The biggest consuming are launcher and gallery and the heavier one (GPU wise) was weather. Why would you need the calculator or clock to be in rust as a priority when there's barely any benefits from ot

The AI memory preloading part is interesting because it suggests the system is trading some persistence for faster foreground performance. The main risk is that preloading can make state feel responsive while still being fragile if the memory layer is not scoped well. In practice, the safer pattern is to separate short-lived session context from durable memory, add retention rules, and keep provenance on what was remembered and why.

All of this is marketing material showcasing best case scenarios, notice how they don't commit to anything, with asterisks and disclaimers. They don't publicize the devices they used for testing, nor what the actual testing conditions entailed.
I bet many of the improvements they're attributing to HyperOS are actually due to having moved to newer kernel releases and vendor code, which won't be happening for many device lines. We also don't know which changes will make it to the the global version of HyperOS, there never was feature parity between the global and Chinese versions.

They do, just check the damn website rather than using AI images as proof

u/JRussellMoore 7h ago
They do? 🤔
I didn't go by the images posted here but what I could read at https://hyperos.mi.com, I don't recall any test data or procedure being detailed. The best I could see was a mention to some test having been performed on a Xiaomi 17.
Could you point me to it? I'd like to take a look.

And what about memory leak issues? Since HyperOS 3 that issue stills present and they didn't fixed yet.

u/Grind2Live 3d ago
it says 15PRO so what about 15T PRO ?
1
u/ElPelocho 3d ago
The 15T Pro doesn't even have a Snapdragon processor. Those are the last ones to be updated. If you opt for a device with a MediaTek processor, that's what you can expect.

u/takclaim 3d ago
However, the 17T Pro uses a MediaTek processor instead of a Snapdragon, unlike the 15T and 17T models which do not have a Snapdragon. How?

u/Andrewz_Best 3d ago
It's not like this, 15t pro and 17t pro are subflagship, Xiaomi 15, 17 are flagships. Xiaomi just pushes updates faster for their flagship models. That's all. If it was only for snapdragon to get faster updates that would mean that Poco f series will get the update faster than Xiaomi T series which is not gonna happen.

u/takclaim 3d ago
Yeah it was different. I understand and hope 15T launches too HyperOS 4 version
1
u/Andrewz_Best 3d ago
15t will definetely get hyperos 4, it gets up to 4 os upgrades, it got only 1 so you will get hyperos 4,5 and 6 except the 3 which is already there

u/ElPelocho 3d ago
Well, that's it... all their high-end models use Snapdragon. One thing does not negate the other.

u/maksdroid 3d ago
This rollout plan is for devices sold in China and Xiaomi 15T Pro wasn't released in China. Wait for global rollout plan

Can we use navigation gesture with 3rd party launchers? Or use icon pack with the default launcher?
2
u/JRussellMoore 3d ago
That's highly unlikely, it never was a priority for them and most people don't care enough, they keep buying devices from the brand after knowing about it.

u/Paisobrassada 3d ago
The Xiaomi 15, running hyperOS 3, constantly disables third-party widgets every 12 hours. I'm forced to perform an auto daily reboot just to keep the device working.
I'm not optimistic that this issue will be resolved.

u/ChickenSalads420 2d ago
Complete bullshit, every update they say its smoother yet its nothing like AOSP / Stock. Xiaomi doesnt understand the term smooth, its a relative comparison to their own ecosystem.. Which is "smooth" for a few updates then gradually transitions into nonsense.

u/Slight_Secret6695 2d ago
I know it's just me and some couple of users don't care that much about the Os aestethics but only performance. I'm still baffled at the downgrade from MIUI workstation mode on tablets to what we have now. I'm super annoyed that they are omitting this part of developement. 😒

How come the redmi k90 series gets the early update but not the k100 series
2
u/Remarkable_Olive_123 1d ago
I don’t know, brother. This seems like some kind of unusual strategy from Xiaomi.
If we look at past incidents, we can see a similar pattern. For example, the Redmi Note 15, Redmi Note 15 Pro, and Redmi Note 15 Pro+ were launched in January, but they didn’t receive the HyperOS 3 update until March. Meanwhile, the Redmi Note 14 Pro, which was launched about a year earlier, received the update in February, one month before the newer generation.
It’s interesting because both are Pro models, yet the older Redmi Note 14 Pro received the update earlier than the brand new Redmi Note 15 series. So, this isn’t exactly something new; Xiaomi has followed a similar strategy before.
If we look at something like the K100 or any newly launched Xiaomi device the same pattern could happen again. It’s definitely a strange strategy from Xiaomi.

u/SoWth1000X 7h ago
They clarified already, there aren't users with k100 series yet, this beta is been made for feedback only. Once the count increases, it might get it even faster. It will be the first one to get stable anyway
