Silicon-carbon batteries have been main phones to eyebrow-raising battery life, and the Realme P4 Energy consists of one of many greatest batteries we have seen in a telephone. It is setting a good larger benchmark with a ten,001mAh battery. By comparability, that is double the capability we see in additional mainstream telephones just like the Samsung Galaxy S26 Ultra, which features a 5,000mAh battery.
The Realme telephone surpasses what we have seen in different telephones with any such battery, together with the OnePlus 15‘s 7,300mAh battery and the RedMagic 11 Pro‘s 7,500mAh battery. Telephones with batteries of this scale present as much as two days of use and infrequently have sooner charging speeds to go together with it.
The Realme P4 Energy is at the moment accessible in India — it is unlikely to ever come to the US — however regardless of its chart-topping battery capability, it is comparatively cheap at INR 25,999, or roughly $285. It is just a bit greater than the ten,000mAh battery within the Honor Win, which I received to check out final yr however did not get prolonged time with the intention to actually try it out.
That is why I used to be excited to place my SIM into the Realme P4 Energy, throughout which I used to be in a position to check this telephone via all of CNET’s battery exams, use it as my major system and at the same time as an influence financial institution for my iPhone alongside the way in which.
All that battery with none main drawbacks
It would not sacrifice on design or options to suit a giant battery.
One of the best half concerning the Realme P4 Energy is that it would not sacrifice consolation for extra battery capability. It is not a slim and light-weight telephone however at 9.1mm thick and 219g weight, it’s lighter than some large flagship telephones, together with the iPhone 17 Pro Max and Google Pixel 10 Pro XL.
Realme’s TransView Design has a translucent look across the digicam module, which accentuates its “Energy” branding. I like this distinct design and in-hand really feel. It has curved corners in addition to slight curves on the again that make it straightforward to carry. (Please take observe, Samsung.)
The Realme P4 Energy has a plastic again and body, whereas the entrance is protected by Gorilla Glass 7i. It is usually rated for sturdiness with IP66, IP68 and IP69 dust- and water-resistance rankings. This implies, it might probably survive freshwater submersion and high-pressure water jets and can be protected in opposition to small mud particles.
On the entrance, you get a 6.8-inch AMOLED show with a 2,800×1,280-pixel decision, 144Hz refresh fee, 1,800 nits brightness and 6,500 nits peak brightness for HDR-supported content material. Like many telephones, it’s a must to manually set it to the next decision and refresh fee to make the most of these options.
The display is well legible outside.
I had no points with the display, and utilizing a curved panel after a very long time was a refreshing expertise. It was simply legible outside, and I loved watching movies. Nonetheless, I do not just like the absence of stereo audio system. The system has only one speaker on the backside; whereas it’s loud, you may want to attach your earbuds for a greater film expertise.
I used the Realme P4 Energy in day-to-day life, which included doomscrolling on social media apps like Instagram and X, answering emails and messages on Gmail, WhatsApp and Slack navigating on Maps and snapping a number of images. It comfortably lasted me as much as two days of standard use and one and a half days on heavy use. And if you do have to cost it, you should utilize the bundled charger to prime up the battery at 80 watts.
To higher choose the brand new Realme telephone, I put it via CNET’s 3-hour video streaming check and 45-minute battery endurance check.

How about the whole lot else?
Realme’s “Energy” branding is accentuated by its translucent design across the digicam module.
The Realme P4 Energy has a MediaTek Dimensity 7400 Extremely chipset, paired with as much as 12GB RAM and 256GB storage. (The bottom mannequin has 8GB RAM and 128GB storage.) That is extra of a midrange chip that is in an identical class because the Motorola Razr‘s Dimensity 7400X. It handles day-to-day duties easily, and it has no main flaws. As for minor points, I did discover apps taking longer than common to load generally and the digicam app taking a number of seconds to course of, however these points usually are not a deal-breaker.
Realme’s consumer interface is clean, snappy and extremely customizable. It’s much like OnePlus and Oppo. Nonetheless, you get a number of preloaded apps. (I uninstalled them as quickly as I arrange the telephone.) Total, this Realme UI 7.0 (primarily based on Android 16) is quick and responsive. You will get three years of Android OS upgrades and 4 years of safety upgrades.
The Realme P4 Energy has two rear cameras and a 16-megapixel selfie shooter on the entrance. You get a 50-megapixel predominant digicam and an 8-megapixel ultrawide-angle sensor on the again. Loads of AI-powered instruments can be found that can assist you improve or edit a shot.
The digicam system is passable for a finances smartphone.
It delivers a passable digicam expertise. In daylight, the P4 Energy can snap some handsome images. The colours are largely correct, distinction is balanced and the dynamic vary is first rate. It processes 2x portraits digitally, which works high quality for probably the most half, however at occasions, sure areas can have a cutout-feel to them — such as you’ve been pasted on a background.
Total, the Realme P4 Energy is a good telephone for its glorious battery life. I used to be anticipating it to carry out effectively with its 10,001mAh battery, however I did not anticipate it to blow out each different Android telephone in our exams. I like it extra as a result of this battery innovation is accessible to the plenty, because of its cheaper price and never being gatekept on costlier fashions.
