Summary
The Realme P4 Power’s headline is its colossal 10,000 mAh battery, a rarity in the mid‑range segment. In a dedicated battery‑life suite the phone posted an active‑use score exceeding 25 hours, translating to roughly two full days of screen‑on time, despite a form factor that feels comparable to mainstream flagships like the Galaxy S25 Ultra.
The device’s charging performance surprised the testers: Realme’s 80‑watt SuperVoke fast‑charge pushes the battery from zero to just under 50 % in about thirty minutes, and a complete charge is achieved in roughly 80‑90 minutes. Reverse‑wire charging also proved practical, delivering a noticeable charge to an iPhone 17 Pro in just over an hour while still retaining a full day’s worth of power for the Realme itself.
Realme attributes the endurance to Silicon‑Carbon battery technology and claims the pack will retain 80 % health after eight years, even without battery‑health settings. The reviewer noted the phone isn’t a camera champion, but its battery longevity and ability to act as a portable power bank make it a compelling secondary device.
For power‑hungry users, the P4 Power offers a rare combination of massive capacity, respectable fast‑charging, and reverse‑charging utility, positioning it as a niche leader in endurance‑focused smartphones and prompting competitors to reconsider battery sizing in future mid‑range releases.
