In an era where even mid-range and premium smartphones typically feature 7,000mAh batteries (thanks to silicon-carbon technology), Realme has taken a monumental leap by introducing a device with an astonishing 10,001mAh battery. Modern smartphone chipsets are remarkably power-efficient, ensuring most phones comfortably last over a day, often extending to 1.5 days for casual users. This raises a crucial question for 2026: Is a 10,001mAh battery truly essential, or is it simply excessive? Could you find a better balance of features and performance for the same cost?
Realme P4 Power Design: Surprisingly slim
- Dimensions – 162.26 x 76.15 x 9.08mm
- Weight – 219g
- Durability – IP69 (dust and water)
For a phone engineered for exceptional battery life, the Realme P4 Power is remarkably slender. While silicon-carbon battery technology has enabled slimmer smartphones with impressive power reserves, we’re discussing a 10,001mAh capacity here, not just 7,000mAh.
The Realme P4 Power boasts a slim silhouette thanks to its rounded corners and curved edges.
Despite leveraging silicon-carbon technology for its immense battery, defying the laws of physics remains a challenge, especially for a mid-range device. Given this, Realme’s achievement in integrating such a large battery into a phone that feels only slightly chunky is truly commendable. At 219 grams, it’s noticeably weighty but still manages to be lighter than some premium flagships like the iPhone 17 Pro Max (233 grams).
For a smartphone with such a substantial battery, handling the Realme P4 Power is surprisingly easy and comfortable, thanks to its curved edges and rounded corners. The matte plastic rear panel effectively repels fingerprints and dust. However, the smooth back combined with the matte-finished frame makes the phone quite slippery without a case. Therefore, caution is advised during late-night scrolling sessions over your face, as a slip could result in injury. Additionally, the matte-plastic rear surface is prone to scratches.

As many modern smartphones have moved beyond curved-edge displays, Realme might have adopted this feature specifically for the P4 Power to better accommodate its large battery. The brand advertises a ‘4D-curved screen,’ but in reality, the underlying display appears curved only on its left and right edges. These curved edges, also mirrored on the rear, contribute to the phone’s slim profile even where the curved sides meet flat frames.
The ‘Dart’ branding is a nod to Realme’s power and charging accessories.
The rear camera module maintains a relatively flat profile despite housing three camera sensors and an LED flash. To add a unique touch, Realme designed the upper third of its rear panel with an embossed circuit board-like aesthetic. This peculiar design element resembles a wireless charging coil (though it’s not functional) and features ‘Dart’ branding. For those unfamiliar, ‘Dart’ is Realme’s signature branding for its power banks and chargers. We’ll delve into whether the phone lives up to this moniker in the battery section.
Realme P4 Power Display: The good, the bad and the ugly
- Display size – 6.79-inch, 1,280 x 2,800 pixels (full-HD+)
- Display type – AMOLED, LTPS, 144Hz (60-90-120-144Hz)
- Display protection – Corning Gorilla Glass
For a mid-range device, the Realme P4 Power surprised us with its incredibly thin display bezels. The ‘4D-curved display,’ as Realme calls it, is notably curved only on two sides. While this creates an immersive viewing experience, it also introduces undesirable reflections, especially when used outdoors.
The 144Hz high-refresh rate claim feels largely like a gimmick. Even when manually setting the display to ‘High’ refresh rate (instead of ‘Auto’), the maximum 144Hz is only active within specific applications like Compass and Calculator. Most other software interactions settle at 120Hz, while movies typically run at 90Hz (unless MEMC is enabled), and games are by default capped at 90Hz. Although you can force games to run at 120Hz via App Specific settings, no other applications or software interfaces, besides the two mentioned, can actually utilize the 144Hz limit.
The Realme P4 Power’s display features skinny borders and offers excellent outdoor brightness.
Beyond the refresh rate, the display panel itself is impressively bright, reaching a claimed 1,800 nits in high-brightness mode and a peak brightness of 6,500 nits. Outdoor legibility is superb, and HDR content is rendered with crisp, vibrant visuals where supported, thanks to boosted brightness levels. However, the single bottom-firing speaker, while adequately loud, lacks clarity and sounds unbalanced. It’s also very easy to accidentally block the sound when holding the phone. Given the device’s huge battery, a richer audio experience would have made it an even better long-lasting media player.
The Hyper Vision+ AI chip also includes MEMC-based upscaling, converting standard 30fps video to 120fps, which unfortunately often results in the ‘soap opera effect.’ I frequently observed the chip struggling to keep up with most streaming video content I played on the device.
Realme P4 Power Software: The usual with a dash of AI
- Android version – 16
- Software – Realme UI 7.0
- Software commitment – 3 years OS + 4 years SMR
Realme UI 7.0 offers extensive customization but comes with several preinstalled third-party applications.
Like many other phones released in late 2025, the Realme P4 Power thankfully comes with Android 16 out of the box. Realme UI 7.0 operates smoothly and includes all the advanced features found in premium devices, including various AI functionalities.
The latest iteration of Realme UI is highly customizable, featuring themes, sleek Liquid Glass-inspired icons, new fonts, and an abundance of fluid animations and transitions for users who enjoy personalizing their devices.
AI Image editing on the Realme P4 Power, while not flawless, performs reasonably well.
I tested the AI image editing features, and they performed quite decently. As evident from the provided collage, AI image editing isn’t perfect, occasionally leaving behind traces or outlines, but it’s far from poor. There’s also an AI translator tool, though currently, language options for India are limited to Hindi.
The phone does come with a selection of preinstalled apps such as Snapchat, PhonePe, Spotify, Netflix, LinkedIn, FinShell Pay, and Amazon Music. Fortunately, if these apps aren’t to your liking, they can be uninstalled.
Realme P4 Power Performance: Good enough
- Processor – MediaTek Dimensity 7400 Ultra, 2.6GHz, 4nm
- RAM – 8/12GB (LPDDR4X)
- Storage – 128/256GB (UFS 3.1)
When playing Call of Duty: Mobile (CODM), the game defaults to Very High graphics and Max frame rate, consistently delivering 55-60 fps with generally smooth gameplay. Switching to Low graphics and Ultra frame rate provides an even smoother 90 fps, albeit with occasional minor drops. Enabling the Hyper Vision+ AI chip for MEMC-based upscaling creates a noticeable difference, boosting the motion-enhanced frame rate to 118-120 fps compared to the 60 fps at the highest settings (Very High + Max). While it feels smoother, it doesn’t quite match the fluidity of top-tier flagships. Interestingly, even with the AI Hyper Motion feature active, the display’s refresh rate never reached 144Hz, as indicated by the developer tool.
The display’s touch sampling rate felt somewhat sluggish for first-person shooter (FPS) titles, even after boosting it to ‘Ultra’ within the Game Assistant slide-out console.

During gaming sessions, the phone did not experience any noticeable heating, even with the AI Hyper Motion feature activated for enhanced frame rates. However, the camera app did warm up the phone when recording even basic 1080p video, though it never became uncomfortably hot. I also observed significant lag and stuttering in the video preview within the viewfinder, particularly when recording 1080p at 60 fps. It’s worth noting that the phone does not support 4K 60 fps video recording.
Realme P4 Power Cameras: Not so mid-range
- Primary camera – 50-megapixel, f/1.8, AF, OIS
- Ultra-wide camera – 8-megapixel, f/2.2
- Selfie camera – 16-megapixel f/2.4
The Realme P4 Power features two user-accessible rear cameras.
As is common with many recent Realme smartphones, the brand provides two color processing modes: Vibrant and Natural. True to their names, one delivers punchy, vivid colors, while the other offers more subdued, natural tones that can sometimes appear slightly faded. For this review, I primarily used the default Vibrant mode, as there’s no direct option to disable both modes.
Realme P4 Power primary camera samples.
The primary camera captures good quality photos, featuring decent dynamic range and sufficient detail for a budget to mid-range device. However, some detail is lost due to aggressive sharpening, which becomes apparent upon zooming into images. Colors are slightly saturated, and all images tend to have a noticeably warmer tone.
In low-light or street-lit environments, the overall detail level diminishes. While noise is effectively controlled and suppressed, this reduction in sharpness makes photos appear somewhat soft, and textures can look painterly when magnified. Given the camera’s optical image stabilization, better results were expected. The phone struggles to handle dimly lit scenes effectively, often resulting in soft, detail-lacking images.
Realme P4 Power ultrawide camera samples.
The ultra-wide camera largely serves to fill the spec sheet. Its low-resolution sensor and subpar processing produce images that are soft and lack sufficient detail, even in bright daylight conditions.
Portrait mode from the primary camera (top), Portrait mode on the selfie camera (bottom).
Portrait photos taken with the primary camera appear decent, with good detail and average edge detection. However, selfie camera samples tend to be a bit soft and exhibit fuzzy edge detection.
Daylight video recordings are satisfactory, offering decent detail at 1080p and improved detail at 4K resolution when shooting at 30 fps. Autofocus is reasonably quick. Stabilization is acceptable, and dynamic range is average, meaning some distant objects may not be clearly visible in bright conditions. In low-light or street-lit conditions, colors are maintained, but aggressive noise reduction leads to soft videos with blotchy textures and a lack of detail.
While 1080p 60 fps video recordings offer a higher frame rate, I observed some focus hunting in both daylight and low-light scenarios. The phone also became noticeably warm during this, and the viewfinder struggled with lag and stuttering. Fortunately, the recorded footage itself did not show these issues. A notable observation across all recording resolutions is a significant crop (1.5X-2X), likely implemented to enhance stabilization.
Realme P4 Power Battery: A powerbank with a catch
- Battery capacity – 10,001mAh,
- Wired charging – 80W Ultra Charge/SuperVOOC, 55W PPS
- Reverse wired charging – 27W
- Charger in the box – Yes
As battery capacities escalate, every percentage point becomes critical. With the Realme P4 Power, even if you’re down to 5 percent, you can still expect about 1.5 hours of normal phone operation before needing to activate Power Saver mode. For those concerned about long-term battery health, Realme asserts that they’ve implemented a specialized charging algorithm to minimize degradation, acknowledging that users won’t charge such a device as frequently as a typical smartphone. This is crucial, as the brand confidently claims its massive battery should endure for 8 years before showing significant signs of wear (maintaining at least 80 percent of its original capacity).
PCMark’s Work Battery Life test yielded an impressive result of 28 hours and 41 minutes. I personally observed abnormally generous battery times during my use. For casual users who avoid gaming, the phone will effortlessly last over two days on a single charge. Even for heavy users constantly on calls, messaging, gaming, and using the camera, the phone will still comfortably last over 1.5 days without needing to plug in.
The 80W SuperVOOC charger delivers ample power for rapid phone charging.
Given the abnormally large battery, the charging speeds are quite impressive. The bundled 80W charger brought the 10,001mAh battery from 0 to 31 percent in just 30 minutes, and to 71 percent in an hour—a praiseworthy feat, essentially charging 7,000mAh in that timeframe. The phone achieved a full charge in 1 hour and 55 minutes.
Realme states that its P4 Power can provide 27W of reverse charge power, capable of charging an iPhone 16 Pro to 50 percent in 27 minutes. I couldn’t verify this claim directly as I didn’t have that specific device. However, I did test it with an iPhone 15 Pro Max, which has a 4,441 mAh battery. The Realme P4 Power charged the iPhone 15 Pro Max from 42 percent to 76 percent in 30 minutes, and to 92 percent in an hour. This indicates a significant drop or alteration in charging speed after the initial 30 minutes.
The Realme P4 Power charging an iPhone 15 Pro Max.
Essentially, the P4 Power delivered a 49 percent charge to the iPhone’s smaller battery within the first hour, while only losing 28 percent of its own battery power during the process. This isn’t bad for emergency situations. Nevertheless, it’s slower compared to typical power banks, which generally charge at a consistent 30W or higher.
Regardless, Realme’s claim of charging an iPhone 16 Pro to 50 percent in 27 minutes appears quite accurate. However, it’s important to remember that the iPhone 16 Pro has a relatively modest battery capacity of 3,582mAh. Even basic budget Android devices now feature 5,000mAh batteries, with most mid-range and premium models packing 6,000 to 7,000mAh. In essence, you can fully charge iPhones and Android devices with batteries up to 5,000mAh, but for larger capacities, you’ll need to be prepared for a considerably longer wait.
Realme P4 Power Verdict
Undeniably, the 10,001mAh battery inside the Realme P4 Power might seem excessive in today’s landscape, given that most smartphones can already comfortably deliver around 1.5 days of battery life with smart usage. However, for ‘road warriors’ who frequently find themselves away from charging points, this smartphone offers precisely what it promises without adding significant bulk. For a large-battery smartphone, the Realme P4 Power truly sets new benchmarks. It effectively provides the battery endurance of two phones in one device, eliminating the need to carry a separate power bank. Yet, battery life isn’t the only metric that matters. Beyond its power bank-like features, the Realme P4 Power makes compromises in its camera hardware and overall raw performance. As always, the market abounds with alternatives.
The OnePlus Nord CE 5 stands as its closest rival, with last year’s Redmi Note 14 Pro+ securing a respectable second position. Priced at Rs. 24,999 (for the 8+128GB variant), the Nord CE 5 offers superior performance at the same price point, boasts capable cameras, and features a 7,100mAh battery that, despite its ‘lower’ capacity, still delivers around 2 days of casual usage. With the Redmi Note 15 Pro’s price already increasing this year, we believe the Redmi Note 14 Pro+ (at Rs. 27,000) presents better value with its clean IP68-rated design, good cameras (including telephoto capabilities), and impressive battery life. Finally, if your budget allows for a stretch to Rs. 29,999, Motorola’s Edge 60 Pro (8+256GB) provides even better raw performance and an impressive camera setup at a slightly higher asking price, all packaged in a very premium design. However, it doesn’t quite match the Nord CE 5 and P4 Power in terms of sheer battery endurance.
