Introduced at the turn of 2021 and notable for being the first shipping phone with Qualcomm’s Snapdragon 888, the Xiaomi Mi 11 positions itself as a full‑feature Android flagship. Hardware highlights from launch coverage include a 6.81‑inch Quad HD+ AMOLED display capable of 120 Hz refresh, a 108 MP primary camera, 8 GB or 12 GB RAM options, and fast charging support (55W wired, 50W wireless). Design cues mentioned in hands‑on reporting include a “waterfall” curved display and a distinctive camera pod on the upper left of the back.
This review synthesizes published hands‑on and long‑term coverage and test data from HotHardware, GSMArena, UL (benchmarks), and DXOMARK. Sources include performance benchmarks (3DMark Wild Life series), a long‑term usability and thermal summary, and DXOMARK’s display protocol notes — together they form the basis for conclusions about daily responsiveness, thermal behavior under load, display quality and charging characteristics.
High‑level verdict: the Mi 11 delivers class‑leading smoothness and a best‑in‑class display for its generation, backed by Snapdragon 888 performance and aggressive wired/wireless charging. Trade‑offs are real and specific: sustained benchmark runs can trigger thermal behaviour and potential throttling in worst‑case lab runs, battery life numbers are sensitive to screen brightness and refresh rate, and some reviewers flagged questions about carrier/network specifics in certain markets. For buyers prioritizing raw speed, display fidelity and fast charging, the Mi 11 is a strong pick; those who need peak sustained loads or definitive carrier guarantees should verify suitability first.
Top‑tier Snapdragon 888 speed, but watch sustained loads
Benchmarks recorded by UL show strong GPU results for the Mi 11: 3DMark Wild Life scored a median 5030 and Wild Life Unlimited 5342 with a stability figure of 91% and a graphics test result near 30 FPS in that protocol. GSMArena’s long‑term review describes the handset as the smoothest phone they’d used in that period, crediting the Snapdragon 888 and the 120 Hz panel plus a 480 Hz touch sampling rate for the consistently fluid UI.
That said, reviewers cautioned that running back‑to‑back synthetic benchmarks can induce thermal stress and measurable throttling — GSMArena noted that excessive consecutive tests can produce heating and reduced performance even if everyday use remains unaffected. In short: excellent peak performance and everyday responsiveness, but predictable thermal constraints under continuous maximum load.
A big, sharp QHD+ AMOLED with high refresh and touch rates
The Mi 11’s 6.81‑inch AMOLED panel uses a 3200 × 1440 pixel resolution for about 515 ppi (DXOMARK lists the display dimensions and 515 ppi), and supports up to 120 Hz refresh. DXOMARK’s display testing highlights the model as a marked improvement for Xiaomi in the display department and notes that some protocol tests were run at a 60 Hz default setting — an important detail because refresh rate choice affects battery and perceived smoothness.
Practical implications: the panel delivers one of the smoothest UI experiences available in its generation thanks to 120 Hz and a 480 Hz touch sampling rate (reported by GSMArena), making scrolling and touch input feel very responsive. Users should be mindful of the power cost of QHD+ at 120 Hz versus lower refresh or resolution settings when optimizing for battery life.
Very fast wired and wireless charging; usable battery life depends on settings
Xiaomi equips the Mi 11 with fast charging capabilities that reviewers highlighted: 55W wired charging plus 50W wireless charging (as noted in HotHardware coverage). Those are among the faster wired and wireless charging numbers available at launch and make for quick top‑ups compared with typical flagship wireless speeds of the era.
Battery life test data in UL’s aggregated results show a wide range of runtimes because battery tests are highly sensitive to screen brightness and refresh rate; UL explicitly recommends calibrating tests to 200 cd/m² to get consistent results. Expect usable day‑long battery life in normal mixed use, but significantly reduced runtimes if you run QHD+ at 120 Hz and high brightness continuously.
A 108 MP main sensor with a capable triple‑camera array — solid but not exhaustively profiled here
Xiaomi packed a 108 MP primary camera into a triple‑camera module on the Mi 11, which was a headline spec at launch and highlighted repeatedly in hands‑on coverage. HotHardware and the spec sheets list the 108 MP main shooter as the focal point of the imaging system; GSMArena’s long‑term coverage treated general camera usability as part of the handset’s everyday strengths.
This review relies on published coverage and display testing; full DXOMARK camera lab scores are not included in the cited display retest. The available material supports that the Mi 11 is well equipped on paper (108 MP main plus additional rear sensors), but readers seeking detailed low‑light, telephoto, and computational‑photography comparisons should consult dedicated camera tests.
Flagship industrial design with recognizable Mi styling and MIUI polish
Visually the Mi 11 is described as a typical glass‑and‑aluminum flagship with a 6.81‑inch waterfall display, a unique camera pod on the top left of the back, and several color/material options called out in launch coverage. DXOMARK lists physical dimensions at 164.3 × 74.6 × 8.1–8.6 mm, confirming a large handset footprint and high screen‑to‑body ratio (~91% as noted).
Software and daily UX were praised for smoothness in GSMArena’s long‑term review; MIUI atop Android delivered fluid animations and consistent responsiveness. As with most MIUI builds of that period, buyers should expect Xiaomi’s UI customizations and frequent updates in some regions — confirm update and carrier support specifics where network compatibility matters.
Pros & Cons
- ✅ Snapdragon 888 platform with strong real‑world smoothness and high benchmark scores (3DMark Wild Life ~5030, Wild Life Unlimited ~5342, stability ~91%)
- ✅ 6.81" QHD+ AMOLED display with 120 Hz refresh and ~515 ppi for very smooth, high‑resolution viewing
- ✅ 108 MP main camera in a triple‑camera module provides a high‑resolution primary sensor
- ✅ Very fast charging: 55W wired and 50W wireless support for rapid top‑ups
- ✅ High touch sampling (reported 480 Hz) and responsive UI noted in long‑term testing
- ❌ Sustained, back‑to‑back benchmark runs can cause thermal build‑up and measurable throttling in lab conditions
- ❌ Battery runtime is sensitive to brightness and refresh‑rate settings; aggregated benchmarks show wide variance without a fixed 200 cd/m² calibration
- ❌ Some reviewers raised questions about US network/carrier support and compatibility details for certain markets
How It Compares to the Competition
- Samsung Galaxy S21 — Similar flagship performance and compact software polish; the Mi 11 traded blows on display specs and charging but reviewers compared the two on network and ecosystem differences.
- OnePlus 9 — Another Snapdragon 888 phone with a focus on smooth UI; OnePlus emphasizes a cleaner OS experience while the Mi 11 offers higher display resolution and faster wireless charging on paper.
- Xiaomi Mi 10 (previous gen) — The prior‑generation Mi 10 shares design lineage but the Mi 11 upgrades to Snapdragon 888, a QHD+ 120Hz panel and faster wired/wireless charging.
Who Should Buy This & Who Should Skip It
Buy it if: Buy the Mi 11 if you want one of the best OLED panels of its generation, top‑tier Snapdragon 888 peak performance, and very fast wired and wireless charging. It’s a strong choice for power users who prioritize display fidelity, snappy UI and rapid charging over guaranteed carrier support in every market.
Skip it if: Skip the Mi 11 if you need verified carrier compatibility for a specific US network without checking bands, or if your workload involves sustained maximum‑load compute where extended thermal throttling would be a problem. Also consider other options if you prefer guaranteed longer battery runtimes at QHD+ 120 Hz without manually tuning display settings.
