The device in question is the Realme Power, which surfaced on China’s TENAA certification database with model number RMX5166. This appears to be the Chinese version of the phone known globally as the Realme P4 Power. The TENAA listing provides detailed hardware information ahead of its expected official debut in China.
Realme Power Appears on TENAA with Complete Specs
A new Realme smartphone has shown up on China’s TENAA certification site, revealing its full specifications. The model RMX5166, likely to launch as the Realme Power in the Chinese market, matches closely with the Realme P4 Power already introduced in other regions, particularly India.
TENAA listings often provide reliable details on upcoming devices, including dimensions, battery ratings, and core hardware. This certification indicates the phone is close to launch, as such approvals typically precede public announcements.
Key Specifications from TENAA
The Realme Power (RMX5166) includes these main features based on the certification:

- Processor: Octa-core chipset running at up to 2.6GHz, corresponding to the MediaTek Dimensity 7400 Ultra.
- Battery: Rated capacity of 9,750mAh (advertised figures in other markets reach around 10,001mAh typical).
- Cameras: Rear setup with a 50MP main sensor and an 8MP secondary lens; front camera at 16MP.

What This Means for the Launch
With TENAA approval complete, the Realme Power should arrive in China soon. The specs align almost exactly with the P4 Power variant sold elsewhere, suggesting Realme is using a naming adjustment for different regions—dropping “P4” for the domestic Chinese lineup.
This phone targets users who prioritize long battery life in a mid-range device. The large battery stands out as a main draw, paired with a capable display and solid performance from the Dimensity chipset.
No official launch date has been shared yet, but expect more details from Realme in the coming weeks.
