The Poco M8 Power is launching in India on August 4, 2026 at 12 PM on Flipkart. The biggest highlight of this phone is its 8000mAh battery.
Poco claims it can deliver up to 3 days of battery life and 28 hours of video playback, but real-world performance depends on how you use the device. With regular activities such as social media, gaming, camera usage, streaming, and 5G connectivity, most users can expect around 1.5 to 2 days of battery backup on a single charge. If you are looking for the Best 5G Phone Under 15000, it is important to evaluate real-life battery performance rather than relying only on brand claims, as everyday usage provides a more accurate picture of long-term reliability and value.
Important Note: The Poco M8 Power has not launched yet. We have not tested this phone. This article is based on official specs, company claims, and comparison with other big battery phones. We will update this with real testing results after launch.
