Based on this review alone: buy it if you care about massive 10,001mah battery provides exceptional endurance — just accept slightly heavy at 224 grams.
The reviewer concludes that the realme P4 Power is a 'beast' in terms of battery life, offering unmatched endurance for its price point below ₹25,000. It is highly recommended for users who prioritize long battery life, such as delivery personnel, frequent travelers, or those who need to avoid constant charging.
This review provides an in-depth look at the realme P4 Power, focusing extensively on its 10,000mAh battery performance after 15 days of testing. It examines battery drain under various usage scenarios, charging speeds, and reverse charging capabilities. Additionally, the reviewer covers the phone's design, display, build quality, performance, and camera features.
The realme P4 Power is a battery beast, setting a new standard for longevity at its price point, making it ideal for users who prioritize extended usage. Testing showed a continuous screen-on time of 11-12 hours on 5G data, and it can sustain 6 hours of continuous BGMI gaming, while also fully charging a 7,000mAh phone to over 90% capacity. Despite its slight heft and a single speaker, the 80W SuperVOOC charger replenishes the massive battery from 0 to 100% in just 1 hour and 35 minutes, a surprisingly fast feat. If you need a phone that can easily last two days on a single charge and double as an emergency power bank, this device is an excellent choice. However, if top-tier gaming performance or a premium stereo audio experience are your main priorities, you might want to explore other options.
