Xiaomi’s Redmi Note 17 5G delivers a major battery-life improvement over its predecessor, according to endurance and charging tests. Its 7,700mAh silicon-carbon battery produced an Active Use Score of almost 20 hours, while the phone’s 45W charging system took close to an hour and a half to reach a full charge.

The result places the Redmi Note 17 5G among the longer-lasting mid-range phones tested, although buyers who value fast top-ups may find its charging performance less impressive. Xiaomi also offers 22.5W reverse charging, allowing the phone to share power with compatible accessories.

Redmi Note 17 5G battery life

The Redmi Note 17 5G improved its Active Use Score by nearly five and a half hours compared with the Redmi Note 15 5G. That gain closely tracks the battery upgrade: capacity increased by 39%, while the test score rose by 38%.

The newer phone also has a larger display. It uses a 6.99-inch OLED panel with 1080p-plus resolution and a 120Hz refresh rate, compared with the 6.77-inch OLED screen on the previous model. Despite the extra screen area, the Redmi Note 17 5G delivered a small efficiency improvement.

With an Active Use Score close to 20 hours, the phone should last two to three days between charges for many users, depending on their usage. Heavy gaming, mobile data use and high screen brightness will reduce that figure.

How the Redmi compares with rival phones

The Redmi Note 17 5G outlasted the Redmi Note 17 Pro despite the Pro model having an 8,340mAh battery. The Pro’s endurance was lower, which makes the standard model the stronger option for battery life within the range.

Realme’s 16T lasted around three hours longer overall. It has an 8,000mAh battery and performed better in the call, web browsing and gaming tests, although it fell behind the Redmi during video playback. Its 6.81-inch display uses a 144Hz refresh rate, 720p-plus resolution and IPS LCD technology.

The Poco M8 Pro also offers a different balance. Its 6,500mAh battery is smaller, but its 100W charging system delivered a much faster result. Samsung’s Galaxy A37, meanwhile, could not match the Redmi’s endurance with its 5,000mAh battery.

45W charging is the Redmi Note 17 5G’s weak point

The included 45W charger restored almost 25% of the battery in 15 minutes. After 30 minutes, the phone reached 41%, which should provide a useful day of power for many users. However, a complete recharge takes nearly 90 minutes.

The Poco M8 Pro reached 83% after 30 minutes, highlighting the practical advantage of its 100W system. The Redmi Note 17 Pro has a larger battery and supports faster 67W charging, yet it finished only five minutes ahead of the standard Redmi in the full-charge test.

The Redmi Note 17 5G therefore makes its biggest generational gain through battery capacity and endurance rather than charging speed. Its 45W charging is adequate, but a 67W upgrade would have made the phone more competitive for users who frequently recharge during the day.
