Redmi Note 17 4G Battery Test: Huge 7,700mAh Battery Delivers Strong Endurance

Xiaomi is continuing to offer a 4G version of its popular Redmi Note series, and the Redmi Note 17 4G puts a major focus on battery life. The phone comes with a massive 7,700mAh silicon-carbon battery and 45W wired charging, making endurance one of its biggest selling points.

After testing the Redmi Note 17 5G, battery and charging tests for the 4G model are now available, giving us a closer look at how well Xiaomi's more affordable variant performs in everyday use.

Redmi Note 17 4G Battery Capacity

The Redmi Note 17 4G is equipped with a 7,700mAh Si/C battery, which is significantly larger than the battery found in the previous-generation Redmi Note 15 4G.

The phone supports 45W wired charging, while reverse wired charging is also available at up to 22.5W. This combination gives the Redmi Note 17 4G a strong advantage for users who prioritize long battery life.

The large battery is particularly useful for users who spend considerable time browsing the web, watching videos, using social media or playing games.

Redmi Note 17 4G Battery Life Test

The Redmi Note 17 4G achieved an Active Use Score of 18 hours and 55 minutes in battery testing.

This is an impressive result for a mid-range smartphone and means many users should be able to get through a full day of heavy use without reaching for the charger. With lighter usage, the phone can potentially last considerably longer.

The 4G model shares its large battery with the Redmi Note 17 5G, which also features a 7,700mAh capacity. The main hardware difference between the two models is their chipsets and network connectivity.

45W Charging Performance

While the battery is impressive, charging speeds are more modest.

The Redmi Note 17 4G supports 45W wired charging. Testing shows that the phone reaches around 23% charge after 15 minutes and approximately 40% after 30 minutes.

A complete charge from 0% to 100% takes approximately 1 hour and 28 minutes.

That charging time is reasonable considering the phone's very large 7,700mAh battery, although some competitors offer substantially faster charging systems.

For example, the Poco M8 Pro has a smaller 6,500mAh battery but supports 100W charging and can reach around 83% after 30 minutes.

Large Battery Is the Redmi Note 17's Biggest Upgrade

The Redmi Note 17 4G's battery represents one of the most significant upgrades in this generation.

The phone also features a large 6.99-inch 1080p+ display with a 120Hz refresh rate, meaning the 7,700mAh battery has to power a relatively large and fast display. Despite that, the device manages to deliver strong endurance.

The Redmi Note 17 4G is powered by the Snapdragon 6s 4G Gen 2, paired with up to 8GB of RAM and up to 256GB of storage depending on the market.

Redmi Note 17 4G vs Redmi Note 17 5G

The Redmi Note 17 4G and 5G models are closely related. Both phones feature a 7,700mAh battery and 45W charging.

The biggest difference is the processor. The 5G model uses the Snapdragon 4 Gen 4, while the 4G version comes with the Snapdragon 6s 4G Gen 2. The 5G chipset is manufactured using a newer process and offers newer CPU architecture.

For buyers who do not need 5G connectivity, the Redmi Note 17 4G focuses more heavily on battery capacity and everyday usability.

Verdict

The Redmi Note 17 4G delivers impressive battery endurance thanks to its huge 7,700mAh silicon-carbon battery. Its 18:55 Active Use Score puts it among the more endurance-focused phones in its category.

The main weakness is charging speed. Although 45W charging is respectable, the phone takes around 1 hour and 28 minutes to reach a full charge. A faster 67W or 100W system would have made the device even more competitive.

Overall, the Redmi Note 17 4G is particularly attractive for users who prioritize long battery life over 5G connectivity and high-end performance.
