Realme has confirmed that the Realme P4 Power 5G will launch in India on January 29, 2026, at 12 PM, and the smartphone will be sold online via Flipkart. The phone is said to have 32.5 hours of video playback on a single charge.

Realme P4 Power 5G teasers suggest the upcoming India launch of a battery-first smartphone designed for long endurance, slim design and gamer-friendly charging innovations. Formal advertising highlights a 1.5 days of real-world performance on a single charge of a massive battery-claiming (compared to its competitors), which consumes two full top-ups to achieve the same performance, as well as 27W reverse charging and Bypass technology to allow the gamer to control heat. With the new Realme P4 series, the brand is shifting focus from raw specs to real-world battery reliability and sustained performance.

Massive battery smartphone

The Realme P4 Power 5G is being positioned as a massive battery smartphone built for users who prioritise endurance over frequent charging. Marketing blasts lay stress on the high capacity-cell of P4 Power 5G being the main feature in its headline act and that it has an endurance that goes beyond heavy streaming, navigation and social scrolls without having to hunt down outlets during the midday. Realme claims up to 1.5 days battery life on a single charge, even with heavy streaming, navigation and social media usage. This battery-centric 5G phone targets commuters, gamers and content consumers who want reliability without power anxiety.

As opposed to standard flagships relying on dynamic power-saving to throttle displays, realme ensures a consistent 90Hz Always-on display with peak smoothness remains unaffected as the battery is depleted to 10% with the device still thermally cool. The endurance advantage aims at commuters and power users who are sick of charging cords, and the phone itself has a frame called Pocket Friendly that is only 218g which is remarkably small given the size of the battery pack. All these raise the P4 Power to the next level and makes it a strategic epicenter of Android ecosystems where the outlets frequently outnumber the accessories. Despite its large battery, Realme aims to market the P4 Power 5G as a slim battery phone at just 218g.

Realme P4 Power: 27W reverse charging

Unlike most phones in its class, the Realme P4 Power 5G supports 27W reverse charging, allowing it to double as a practical power bank. Not the usual 5W/10W offering of those in the crowd, the P4 Power 5G only has 27W reverse charging to charge earbuds, smartwatches or even another phone at useful speeds, making it an on-the-go lifeline to users needing to charge multiple devices. With Bypass charging technology, power is drawn directly from the wall during gaming sessions, reducing heat buildup and battery stress. Combined with Bypass Charging, it switches power directly off the wall when playing a marathon game to avoid battery stress and thermal impact to sustain frame rates without thermal throttling. These features position the device as a gaming-focused 5G phone with sustained frame rates and minimal thermal throttling.

Realme P4 Power battery

Despite housing a large battery, the Realme P4 Power 5G aims to be a slim battery phone at just 218g. Realme promises consistent 90Hz and 120Hz display performance without throttling, even when battery levels drop below 10%. The realme P4 Power 5G is getting the Pocket Friendly label at 218g when it is running what teasers claim as a colossal cell and this is a blessing in a battery-first phone that would otherwise weigh in excess of 250g. 

The Realme P4 Power 5G is being positioned as a massive battery smartphone for users who value long screen-on time and fewer charging cycles. A daring 8 years long life warranty promises quality of construction, software release and component life, and has been targeted to the consumer segment of potential buyers who want to find future upholding in the under-Rs20,000 segment.
