Breaks your night into deep, light, and REM stages. Shows you exactly when you were tossing around versus actually getting rest.
Bigger screen than the Band 9, bright enough to check at 3am without blinding yourself. Always-on display option too.
Charge it once and forget about it for almost three weeks. Thats less time plugged in than most smartwatches give you in 2 days.
Tracks blood oxygen overnight along with continuous heart rate. Useful if you snore or suspect sleep apnea is messing with your rest.
A $50 Sleep Tracker That Punches Up
Xiaomi’s Smart Band line has always been the budget king of fitness trackers, and the Band 10 keeps that going. For under fifty bucks you get sleep tracking that honestly rivals what Fitbit charges twice as much for. It logs your sleep stages, monitors SpO2 through the night, and even tracks your breathing quality. The Mi Fitness app breaks it all down in the morning with a sleep score and timeline.
The screen got bumped up to 1.47 inches this time around, which makes a real difference when you’re squinting at your wrist in a dark bedroom. AMOLED means the colors pop and the blacks are actually black, so checking the time at night doesnt feel like staring into a flashlight. The always-on display drains a bit more battery but its worth it if you check the time a lot.
Battery life is the standout spec here. Twenty days on a single charge means you can track multiple full sleep cycles without ever thinking about the charger. Most people I know with Apple Watches or Galaxy Watches end up missing sleep data because they forgot to charge before bed. Thats just not an issue here. My one complaint is the Mi Fitness app — its functional but the UI feels dated compared to what Fitbit and Garmin offer. The data is all there, it just takes an extra tap or two to find what you want.

Common Questions
Is the sleep tracking accurate?
Its solid for a budget tracker. It gets sleep and wake times right, and the stage breakdown lines up pretty close with what more expensive devices show. Not medical grade but good enough for daily tracking.
Can I wear it in the shower?
Yes, its rated 5 ATM which means it handles showers, swimming pools, and rain without any issues. Just dont take it scuba diving.
Does it work as a silent alarm?
Yeah, it vibrates on your wrist to wake you up without disturbing anyone else in bed. You can also set smart wake which tries to buzz you during a lighter sleep phase within a window you choose.
The Verdict
If you want to track your sleep without dropping $200 on a smartwatch, the Xiaomi Mi Smart Band 10 is the move. The sleep data is detailed, the battery lasts forever, and you wont notice its on your wrist. The app could use some work but the hardware itself is hard to beat at this price point.
