Design and Durability
The Poco X8 Power is slightly larger but surprisingly manages to remain lighter than you might expect for a phone carrying a 10,000mAh battery. It measures 163.4 x 78.3 x 8.6mm and weighs 229 grams.
Its construction includes Gorilla Glass Victus 2 on the front, along with a plastic frame and back. Poco has also given the phone IP68/IP69K protection and claims drop resistance of up to 3 meters.
The Realme P4 Power is a little smaller and lighter at 162.3 x 76.2 x 9.1mm and 219 grams. It uses Gorilla Glass 7i and offers IP69 protection along with MIL-STD-810H compliance.
Verdict: Poco has the stronger water and dust protection, while Realme has the advantage in weight.
Display: Poco X8 Power vs Realme P4 Power
Both smartphones use large AMOLED panels with sharp 1.5K-class resolutions.
The Poco X8 Power has a 6.83-inch AMOLED display with a 120Hz refresh rate, HDR10+, Dolby Vision and up to 3,500 nits peak brightness. It also supports 3,840Hz PWM dimming, which should be useful for users who are sensitive to display flicker.
The Realme P4 Power has a slightly smaller 6.8-inch AMOLED panel but pushes the refresh rate to 144Hz. Its headline specification is its claimed 6,500-nit peak brightness, while typical brightness is listed at 600 nits and HBM brightness at 1,800 nits.
For scrolling and supported games, Realme’s 144Hz refresh rate is attractive. However, Poco brings Dolby Vision and a higher 3,840Hz PWM specification.
Verdict: Realme wins on refresh rate and quoted peak brightness, while Poco offers a more feature-rich display package.
Performance and Software
The Poco X8 Power is powered by the Snapdragon 6 Gen 5, a 4nm chipset with four Cortex-A78 cores clocked at up to 2.6GHz and four Cortex-A55 cores at up to 2.0GHz. Graphics are handled by the Adreno 812 GPU.
The Realme P4 Power uses the Dimensity 7400 Ultra, also built on a 4nm process. Its CPU configuration is similar on paper, with four Cortex-A78 cores at 2.6GHz and four Cortex-A55 cores at 2.0GHz, but it uses the Mali-G615 MC2 GPU.
One important advantage for Realme is storage. The P4 Power comes with UFS 3.1, while Poco uses UFS 2.2. Faster storage can make a noticeable difference when installing applications, transferring large files and loading data.
Realme also offers a 12GB RAM/256GB variant, whereas Poco’s listed configurations top out at 8GB RAM.
Both phones run Android 16, but Poco uses HyperOS 3 and promises up to four major OS updates. Realme UI 7.0 is paired with up to three major OS updates.
Verdict: Realme has the stronger memory and storage configuration, while Poco has the longer stated major Android update support.
Camera Comparison
Neither phone is positioned as a camera-first flagship, but both offer a 50MP primary camera paired with an 8MP ultrawide.
The Poco X8 Power’s main camera has an f/1.5 aperture, PDAF and OIS. Its ultrawide camera offers a 120-degree field of view. The phone can record 4K video at 30fps, while the 32MP selfie camera also supports 4K recording.
Realme uses a 50MP f/1.8 primary camera with PDAF and OIS, along with an 8MP 112-degree ultrawide camera. It can also record 4K video at 30fps, with additional 1080p recording options.
On paper, Poco has a clear advantage for selfies and video calls because of its 32MP front camera, compared with Realme’s 16MP sensor.
Verdict: Poco X8 Power wins the camera specification comparison, particularly for the selfie camera and primary camera aperture.
Battery and Charging
Battery life is the biggest attraction of both smartphones.
The Poco X8 Power features a 10,000mAh battery and supports 100W wired charging. It also supports PD3.0 and PPS, 27W reverse wired charging and bypass charging.
Realme goes even further with a listed 10,001mAh battery, although the difference of 1mAh is meaningless in everyday use. Its charging system supports 80W wired charging, 55W PPS and 13.5W PD/QC, with Realme claiming 50% charging in 36 minutes.
Both phones support 27W reverse wired charging and bypass charging.
In practical terms, both should deliver excellent endurance, but Poco’s 100W charging gives it the edge when you need to refill a huge battery quickly.
Verdict: Poco X8 Power wins on charging speed.
Connectivity and Other Features
The Poco X8 Power stands out with support for dual Nano-SIM and eSIM, allowing up to two active SIMs at once from the listed combination. This gives it considerably more flexibility for users who switch between physical and digital SIMs.
Realme P4 Power uses two Nano-SIM slots and does not list eSIM support.
Both phones include an under-display optical fingerprint scanner, USB Type-C 2.0, infrared connectivity and dual-band wireless connectivity. Neither phone has NFC.
Poco also gets Bluetooth 6.0, while Realme uses Bluetooth 5.4 with aptX HD and LHDC 5 support.
Poco X8 Power vs Realme P4 Power: Price
The Poco X8 Power starts at ₹35,999 in India, making it noticeably more expensive than the Realme P4 Power.
The Realme P4 Power starts at ₹30,899, giving it a price advantage of more than ₹5,000.
That difference matters because Realme also offers a 12GB RAM option and UFS 3.1 storage. Poco justifies some of its premium through features such as 100W charging, eSIM, Gorilla Glass Victus 2, IP68/IP69K protection, Dolby Vision and longer major OS update support.
