Xiaomi's Redmi Note 17 5G features a 7,700mAh battery and supports 45W charging. In battery endurance tests, the new model significantly improved upon its predecessor, the Note 15 5G, achieving a 38% higher Active Use Score despite a larger 6.99-inch display. The device comfortably lasts through a day of heavy use.

While the Redmi Note 17 5G offers efficient performance, competitors like the Realme 16T provide longer endurance with an 8,000mAh battery, though at the cost of lower resolution. The Poco M8 Pro features faster 100W charging, reaching 83% in 30 minutes, compared to the Redmi's 41%. Notably, the Redmi Note 17 Pro, despite a larger 8,340mAh battery, underperformed in endurance tests and charged slower than expected.

Overall, the Redmi Note 17 5G represents a substantial upgrade in battery life for the series, balancing capacity and efficiency effectively against mid-range rivals.
