The Xiaomi 15 Ultra's display seems unchanged in its specifications in comparison to the preceding era. A 6.73-inch QHD OLED panel, it supports adaptive refresh charge in the 1-120Hz variety, features both 1920Hz PWM and DC dimming, and might display as much as 68 billion shades. HDR10+ and Dolby Vision are each at the menu as well.
What has modified, looking at our check effects, is the display's most brightness - we measured 1,599nits in automobile mode, some 300nits better than on the 14 Ultra. In manual mode, the variety was 841nits with Sunlight mode enabled (629nits in any other case). We'd call the telephone's consequences common - it's simply that we would ought to attempt to give an explanation for that's now not a awful factor, given the level in which 'common' is now.
Refresh price is dealt with in greater or much less the standard Xiaomi manner - with a 'Default' (full automobile) mode and Custom modes (120Hz and 60Hz ceilings). Regardless of mode, the phone might be doing its adaptive magic, with the handiest real manipulate you've got over it being the 60Hz cap in one of the custom modes - it'll readily dial right down to 1Hz while idle and it's going to shoot all the manner up to 120Hz in each Custom 120Hz and Default modes. It may even choose any refresh price its algorithms choose to be the right one for the instant - no fixed steps.
We had a somewhat unreliable enjoy with video games, with maximum of our normal titles honestly maintaining a 60fps cap. The frame price and the refresh fee could go above that after we pulled up the gaming application that stated the fps, but in its personal records for the previous moments the body charge could were as much as 60fps.
The 15 Ultra supports HDR10+ and Dolby Vision. YouTube luckily served HDR content material, as did Netflix, also reporting it supported each requirements. High-res video playback of DRM-blanketed content material is covered too, way to the Widevine L1 compliance.
The Android Ultra HDR popular for images is also supported and it is one of the extra straightforward implementations, in which it simply works in which it ought to - Google Photos, Chrome, the in-residence gallery.
The Xiaomi 15 Ultra, in its international shape, is powered by a five,410mAh battery of the silicon carbon kind. It's a welcome growth over the 5,000mAh ability of the preceding version, although lots of this 12 months's... Vital models percent even more mAhs. Now, the 15 Ultra for China does come with a 6,000mAh energy p.C., itself an growth over the Chinese 14 Ultra's five,300mAh capability, however the global gets exceptional numbers.
In our testing, the 15 Ultra showed a marked improvement over the previous technology's results across the board. We clocked thirteen:18h of net browsing, which is greater or less the norm for this yr's flagship fashions, 19:25h of looping movies (at the better cease of the charts), and 10:41h within the gaming take a look at (also longer than maximum). The 40:51h of voice call persistence is also way above common.
The 15 Ultra ships with out a charger, but is rated for up to 90W of power - no longer just with Xiaomi adapters, but ordinary USB Power Delivery ones, provided they can get the numbers right. Still, we examined with a Xiaomi 90W adapter in the end, the one we had from the 14 Ultra - it supports several flavors of PPS, inclusive of 3.6-20V@4.5A, so maybe that's what you have to be searching out while selecting up a third-birthday celebration charger. We were given the very best top energy of around 76W inside the early ranges of the technique, with the same old ramp down as the odds grew.
So with that 90W adapter we clocked a complete price from flat at round fifty one minutes, with the battery indicator showing 72% at the half-hour mark. It's appreciably slower than ultimate year's model, however such are the developments this generation. It's still faster than the S25 Ultra, Pixel 9 Pro XL and the iPhone sixteen Pro Max, for what little that is well worth. The likes of the vivo X200 Pro and the Find X8 Pro are about on par with the Xiaomi, whilst the OnePlus 13 is faster to rate and so too is the Magic7 Pro (albeit in Euro trim with the smaller five,270mAh battery).
We tried with a handful of other Xiaomi adapters we had inside the workplace. For starters, the 120W unit were given us essentially the equal numbers as the 90W one. We also tried a 67W Xiaomi adapter and we actually were given ever so slightly higher effects for pace than the 90W option - forty nine minutes to full, seventy seven% at the half-hour mark, 58W highest electricity. Using the 45W Xiaomi adapter, the consequences weren't pretty as accurate, however decent though - sixty five minutes, 62%, 29W.
It gets extra complicated with aftermarket chargers. We attempted a 100W one and a 65W one, both from respectable manufacturers, and the height energy we got with them was 46W and 39W respectively, for what it really is worth. We were searching at fifty nine% at the 30-minute checkpoint and ninety minutes to complete - basically the equal consequences with either. We'd say the half of-hour effects are alright, but the complete rate time is a piece of a letdown.
The factor is, the cellphone maxes out its charging strength and velocity when the adapter on the other quit of the cable can do PPS at 18-19V, which calls for a PPS profile that goes up to 20V. A lot of the aftermarket adapters do not have this sort of PPS profile - the two that we tried, for example, have PPS as much as 16V or 11V, in which case the telephone prices at round 9V, which apparently limits its pace.
The 15 Ultra functions a stereo speaker device with a down-firing unit on the bottom, and a the front-firing speaker/earpiece combination - there may be now not a grille on the pinnacle plate, so no sound spillage whilst you're on a voice call (if it truly is even ever a attention for every person).
We were given a 'Very Good' score for loudness out of the 15 Ultra, like basically every different excessive-quit smartphone these days, even though the Xiaomi does admittedly have a small gain in the numerical result. The telephone also places out splendid sound exceptional, advanced to that out of the Find X8 Pro and vivo X200 Pro, and likely the Galaxy S25 Ultra. The iPhone sixteen Pro Max simply can be a bit bit better nevertheless.
