Xiaomi Redmi M100 review: specs, battery & used prices

Summary

The Xiaomi Redmi M100 is a 2026 entry-level model built around the Qualcomm Snapdragon 4 Gen 5, a very large 6.9-inch 120 Hz IPS panel and an outsized 7900 mAh battery in a 232-gram body. Our catalog scores it 46 on everyday use, 8 on gaming and 62 on compactness, and the battery axis lands at 98, the figure that defines the whole identity of this phone. The single tracked trim of 6/128 GB was listed at about $295 new, while the 13-megapixel camera keeps the imaging ambitions minimal. The Xiaomi Redmi 15 5G is the preceding big-battery Redmi of the same line, and the Xiaomi Redmi Note 15 5G steps up one tier in the family.

Display and design

The 6.9-inch IPS LCD refreshes at 120 Hz and scores 44 on our screen axis, with an 825-nit brightness figure that is genuinely usable outdoors by entry-level standards. An IP64 rating documents protection against dust and splashes. At 232 grams the body is unmistakably a big-battery build, and the compactness score of 62 says plainly that two-handed use is the default.

Performance

The Snapdragon 4 Gen 5 is Qualcomm's entry platform of 2026, and it yields a gaming axis score of 8 and an everyday axis score of 46 in our measurement. Calls, messaging, video and light apps are the workload this phone is built for; anything heavier will show the entry-tier chip immediately.

Camera

The camera axis score of 3 is the lowest tier of our scale, reflecting a single 13-megapixel main camera with no documented video capture spec. Treat the camera as a functional scanner and daylight snapshot tool and nothing more; the value of this model lives elsewhere in its spec sheet.

Battery and charging

The 7900 mAh battery is the headline, scoring 98 on our battery axis, which places the M100 among the longest-running phones we measure. Wired charging is rated at 45 W for the charge axis score of 26, a sensible pairing that refills the large cell at moderate speed. No wireless tier is documented.

Verdict

The Redmi M100 is a specialization device: a 2026 budget phone that trades camera, gaming and weight for a two-day battery and a bright 120 Hz panel. Used market data is sparse, so the new price of about $295 is the only anchored figure, and at that level the battery axis score of 98 is the argument. Buyers who want everything else should step up the Redmi ladder instead.
