Realme is all set to launch the Realme P4 Power 5G and it is clearly built around one simple idea for 2026: battery anxiety should be a thing of the past.
Battery life and battery endurance has been steadily improving over the last year. Smartphones with 7,000mAh batteries only just starting to feel like the new normal in 2025 across devices.
Realme, however, has chosen not to play that incremental game. Instead, it has gone straight for a headline-grabbing approach, equipping the P4 Power 5G with an enormous 10,001mAh battery designed for users who simply want their phone to last.
Monster battery, crammed into a slim package
On paper, a 10,001mAh battery sounds insane. In real life, it genuinely changes how you use a phone. Realme’s lab claims make that intent clear, with figures of up to 32.5 hours of YouTube, 11.7 hours of BGMI, and around 21.4 hours of navigation. For the right kind of user, this is the sort of battery that makes carrying a power bank feel unnecessary.
To put that into perspective, I have only had the phone for three days. Even in that short window, the battery behaviour has been impossible to ignore. I have been pushing it hard, taking calls, watching videos, shooting clips, snapping photos, and generally not holding back. Despite that, I was still ending the day with close to 50 percent left.
Based on this alone, I would not be surprised if the Realme P4 Power 5G becomes an easy one-and-a-half-day phone on a single charge, and possibly more with lighter use.
The obvious concern with a battery this large is whether the phone feels like a brick. Surprisingly, it does not. Realme has managed to keep the thickness at 9.08mm, which is impressive for what is packed inside.
It is not exactly compact, and the 219g weight is noticeable if you are coming from something lighter. That said, the quad-curved display and curved back help it feel smoother and more comfortable in the hand than the numbers suggest.
Once you move beyond the usual 5,000 to 6,000mAh range, the conversation is no longer just about endurance. Heat, long-term reliability, and battery health over time start to matter more. Realme says the battery should hold up better because you will charge it less often, which makes sense, even if it cannot be fully proven in a short review window.
Charging is more practical than expected. You get 80W fast charging, and in my testing it hit 50 percent in under 40 minutes with smart rapid charging enabled. There is also 27W reverse charging, which is genuinely useful for topping up earbuds, charging a second phone, or having backup power in a pinch.
Top-tier performance & display in a budget
Performance and display are where the Realme P4 Power 5G quietly overdelivers for a budget phone. It runs on the Dimensity 7400 Ultra 5G, built on a 4nm process. This is the same chip used in the Realme P4, and while an Antutu score of just over 8 lakh is decent rather than impressive, real-world performance feels better than the numbers suggest. Day-to-day use is smooth, apps open quickly, multitasking holds steady, and the phone never feels like it is struggling.
For gaming, Realme is clearly prioritising consistency. Like the P4 and P4 Pro, the P4 Power gets the Hyper Vision AI chip, which brings AI-driven optimisations to improve how games look and run. Realme claims stable 90 FPS in BGMI, and in testing, that’s exactly what I got. There is a sizeable cooling system as well, though if you push max settings for long sessions, some fluctuation is still expected over time.
What I like is that Hyper Vision AI is not limited to gaming. It also works with video, through features like AI Hyper Clarity, which upscales 720p content to roughly 1.5K, making videos look cleaner and more detailed.
The display itself is a 1.5K 144Hz panel. The full refresh rate is limited to supported apps and games, but even otherwise, it looks sharp, fluid, and well-balanced for everyday use.
Future-forward design
Design-wise, Realme is clearly chasing a bold, future-forward look, though the semi-transparent back is not quite what the term suggests. It is less transparent and more like a two-part design.
The top section features a crystal-style window that highlights internal-structure detailing, while the lower half switches to a matte finish that feels grippier and does a better job resisting fingerprints.
The camera module adds to that statement-heavy approach, with a raised rectangular island, two large camera rings stacked vertically, and a slim side strip housing the extra lens and flash. Overall, this is a phone that will appeal if you want something visually different. If you prefer clean, minimal designs, it may feel a bit too loud.
Software
On the software front, Realme is promising three years of Android updates and four years of security patches, which is decent for this segment. If the phone ends up priced close to ₹20,000 to ₹22,000, as expected, that update commitment feels fair and in line with what buyers should reasonably expect at this level.
Initial thoughts
Because of embargos, I cannot talk about some aspects just yet, including camera performance. That will come later. What matters right now is understanding what the realme P4 Power is actually built for.
This phone is unapologetically focused on battery life. If your usage involves long gaming sessions, heavy media consumption, or days away from a charger, it makes a lot of sense.
But if you prefer compact phones or charge your phone every night anyway, this will feel more like a flex feature than a genuine must-have for most everyday users.
