Detailed Comparison

Cameras

Google Pixel 7a

64MP main (new) + 13MP ultrawide camera duo with Tensor G2 processing — best cameras at this price point in 2023. Pixel AI features (Magic Eraser, Photo Unblur, Real Tone) trickle down at $499.

Cameras: 64MP main (f/1.89, OIS), 13MP ultrawide (f/2.2), 13MP selfie — meaningful upgrade over Pixel 6a's 12MP main.
Pixel AI features (Magic Eraser, Photo Unblur, Real Tone, Night Sight, Live Translate) all included — flagship Pixel software at $499.
Camera quality near-identical to Pixel 7 in daylight; Pixel 7's larger sensor wins slightly in low light.
No telephoto — Super Res Zoom (digital upscaling on 64MP sensor) substitutes; works up to 8x but quality drops past 2-3x.

Xiaomi 15

What Reviewers Agree On

The best — or one of the very best — compact flagships of 2025: full flagship hardware in a small body with no real spec sacrifices.
The Leica triple 50MP camera is one of the most capable systems available in a compact phone, especially the main and 60mm telephoto.
The display is excellent — flat AMOLED with ~3,200 nits measured peak brightness, very readable in direct sunlight.
Charging is a standout: ~90W wired refills it in roughly 45 minutes to an hour, plus 50W wireless.
It still looks and feels premium after a year of use, with solid build quality and an IP68 rating.

Deal Breakers

HyperOS ships with bloatware you can't uninstall, ads and unsolicited notifications even on a flagship.
The Snapdragon 8 Elite struggles to stay cool under prolonged synthetic or 4K-video loads.
Priced like a flagship (~€999) while a Galaxy S25 or iPhone 16 is cheaper and easier to buy in the US.

Xiaomi 15

A Leica-tuned triple 50MP system that reviewers rate among the best you can get in a compact phone, with a large 1/1.3-inch main sensor and a versatile 60mm telephoto. Pro-grade video is strong via the main sensor.

This is one of the best and most capable camera setups you can currently get in a relatively compact phone.
Xiaomi swapped the Xiaomi 14 sensor for a new JN5 telephoto with a 60mm focal length, paired with a large 1/1.3-inch main sensor.
The telephoto offers 2x optical zoom (46mm) but you can still push to ~6x with an impressive level of detail — a strong pick for buyers who don't need extreme reach.
Portrait shots were compared directly against a Sony a6100 with a 23mm f/1.4 lens (≈35mm equivalent, ~f/2.1 depth of field) and held up well.
The main camera can shoot 8K30 from the main sensor, and that 8K footage is roughly 50% more detailed than 4K30.
4K30 video is consistent with great detail, tasteful colours and good contrast, but 4K60 footage can sometimes look too compressed and mushy.
Third-party apps like MotionCam Pro or MC Pro 24fps unlock truly stunning log video and show what the main sensor is really capable of.
There is good consistency between the lenses and no real issue with the Xiaomi 15's camera in everyday use.
In third-party pro apps the camera is locked to a fixed ~78mm field of view with no optical zoom range, limiting professional workflows outside Xiaomi's own camera app.

Battery & Charging

Google Pixel 7a

4,385mAh battery + Tensor G2 inefficiency = mediocre all-day life. 18W wired charging is slow. FIRST A-series Pixel to support wireless charging (7.5W Qi).

4,385mAh battery — small for a 2023 phone with a power-hungry Tensor G2 chip.
Real-world: ~5 hours of SOT typical, all-day for moderate use but often needing a top-up by evening — most-flagged Pixel 7a complaint.
18W wired charging — slow by 2023 standards. 0-50% in ~30 min, full in ~1h30m.
FIRST A-series Pixel with wireless charging — 7.5W Qi. Not flagship-fast but a meaningful feature add at $499.

Xiaomi 15

A ~5,240mAh cell that beats a Galaxy S25 in head-to-head rundowns and recharges very fast over both wire and wireless — though a HyperOS idle drain divides reviewers.

The Xiaomi 15 packs a larger ~5,240mAh battery versus a Galaxy S25's ~4,000mAh while only being 27g heavier, and ended a head-to-head rundown at 30% vs the S25's 13%.
It charges in around 45 minutes with the 90W adapter in the box, and the reviewer had zero issues with battery life in normal mixed use.
From a fully dead battery a measured charge test reached 66% in 45 minutes, 91% at 1h05m and a full 100% in about 1h15m.
It also supports 50W wireless charging — faster than typical flagship wired speeds — though there are no Qi magnets built in, so you need a 50W-compatible mat for top speed.
Xiaomi says battery can run roughly 25% longer than the Xiaomi 14.
One reviewer reported a real HyperOS idle drain — 15-20 minutes of light morning use (email, WhatsApp, Slack) cost 5-6% and warmed the phone, persisting even on the dimmest setting.
After a year you still get a full-day battery for most users — heavy users may need a quick top-up — and 90W fast charging stays extremely useful.
