Oppo could be preparing a smartphone with an enormous 12,000mAh battery, according to a new certification-related leak. The unidentified device, carrying model number PNC110, has reportedly appeared on China’s MIIT database with a rated battery capacity of 11,640mAh and support for 5G connectivity.
Oppo may be planning another major increase in smartphone battery capacity. An unannounced handset from the Chinese smartphone manufacturer has reportedly surfaced in a certification database, indicating that it could feature a battery with a typical capacity of 12,000mAh.
The device, identified by the model number PNC110, was reportedly spotted on China’s Ministry of Industry and Information Technology (MIIT) database.
According to the report, the handset has a rated battery capacity of 11,640mAh, with a typical capacity of 12,000mAh.
If confirmed, the upcoming smartphone could surpass the Oppo A7 Pro Max, which launched in September 2026 with a 10,000mAh battery.
However, Oppo has not officially announced the new device. Its marketing name, processor, camera specifications, charging speed, price and launch date remain unknown.
Oppo PNC110 Reportedly Listed on China’s MIIT Certification Database
Technology publication XpertPick reports that an unidentified Oppo smartphone has appeared in China’s MIIT certification records.
The device reportedly carries the model number PNC110.
The most important information associated with the listing is its battery capacity.
According to the report, the smartphone features an 11,640mAh rated battery, corresponding to a typical capacity of 12,000mAh.
The listing also reportedly indicates support for 5G connectivity.
This suggests that Oppo could be preparing a modern smartphone focused on exceptionally high battery capacity rather than a basic feature phone or standalone portable power device.
However, the certification information cited in the report does not reveal the handset’s commercial name.
It also does not identify its display size, chipset, memory configurations, operating system or charging technology.
Certification appearances can indicate that a manufacturer is progressing through regulatory processes, but they do not independently establish an imminent commercial release.
11,640mAh Rated vs 12,000mAh Typical Battery Capacity Explained
One detail in the reported certification deserves particular attention: the difference between rated and typical battery capacity.
The Oppo PNC110 is associated with two figures:
- Rated capacity: 11,640mAh
- Typical capacity: 12,000mAh
These figures are not necessarily contradictory.
Smartphone manufacturers may specify a rated capacity alongside a higher typical capacity.
Rated capacity generally represents a defined minimum under applicable measurement or manufacturing specifications, while typical capacity reflects a representative nominal value.
Both describe characteristics of the battery, rather than indicating two separate batteries.
A 12,000mAh typical capacity would be substantial by smartphone standards.
However, the milliampere-hour figure alone does not establish total battery energy or real-world endurance.
Actual energy storage also depends on battery voltage, while battery life depends on display power consumption, processor efficiency, software behaviour and usage conditions.
Oppo has not provided an official endurance estimate for the PNC110 in the supplied information.
Oppo’s Upcoming Phone Could Surpass the A7 Pro Max
The reported 12,000mAh battery would represent an increase over the Oppo A7 Pro Max, which was introduced in select global markets in September 2026.
According to the supplied specifications, the A7 Pro Max features a 10,000mAh battery with support for 80W wired fast charging.
It is described as the company’s largest-battery smartphone currently available in the report.
If Oppo introduces the PNC110 with a 12,000mAh cell, it would represent a 20 percent increase in advertised typical battery capacity.
That difference could provide additional endurance under comparable operating conditions.
However, a 20 percent larger battery does not guarantee 20 percent longer battery life.
Differences in display technology, chipset efficiency, mobile network activity and software optimisation could significantly influence the outcome.

Display and Performance
The Oppo A7 Pro Max features a 6.78-inch AMOLED display with a resolution of 1,272 × 2,772 pixels.
The panel reportedly supports a refresh rate of up to 120Hz, a touch sampling rate of up to 330Hz and brightness of up to 1,800 nits in high brightness mode.
The handset is powered by Qualcomm’s Snapdragon 4 Gen 5 processor paired with an Adreno 629 GPU, according to the supplied specifications.
It also reportedly offers LPDDR4x RAM and UFS 3.1 internal storage.
The information provided contains differing RAM and storage configurations, so the exact regional variants should be confirmed against Oppo’s official product specifications.
Cameras
For photography, the Oppo A7 Pro Max reportedly features a dual rear camera system.
The main camera uses a 50-megapixel sensor with an f/1.8 aperture and optical image stabilisation.
A 2-megapixel macro camera completes the rear setup.
On the front, the smartphone includes a 50-megapixel selfie camera with an f/2.0 aperture and a stated 100-degree field of view.
Battery and Charging
The A7 Pro Max’s major selling point is its reported 10,000mAh battery.
The smartphone also supports 80W wired charging.
However, the charging speed of the upcoming PNC110 remains unknown.
It would therefore be premature to assume that the new device supports the same charging technology or a faster standard.
Why a 12,000mAh Smartphone Battery Could Matter
Battery endurance remains an important consideration for smartphone buyers, particularly those who regularly travel, play games, stream videos or rely on mobile connectivity throughout the day.
A smartphone equipped with a 12,000mAh battery could potentially reduce how frequently some users need to recharge their devices.
This could be useful for people who spend extended periods away from charging points.
However, a larger battery may introduce engineering trade-offs.
Manufacturers need to balance battery capacity against device thickness, weight, thermal management, charging performance and internal component space.
Without official dimensions or weight information, it is unclear how Oppo intends to accommodate the reported battery.
The supplied certification report also does not identify the battery chemistry or whether the handset uses a single-cell or multi-cell configuration.
Those details will be important in understanding the design of the eventual product.
Will Oppo PNC110 Support Fast Charging?
Although the report identifies a possible 12,000mAh battery, it does not disclose the phone’s charging speed.
This is particularly important for a device with such a large battery capacity.
Higher-capacity batteries can require substantial charging time, depending on the charging system and power management.
For comparison, the Oppo A7 Pro Max reportedly supports 80W wired fast charging.
However, the PNC110 could use a different charging configuration.
There is currently no verified information about wired charging wattage, wireless charging, reverse charging or whether a power adapter will be included.
Charging time estimates should therefore be avoided until Oppo announces the relevant specifications.
Oppo’s 12,000mAh Phone May Offer 5G Connectivity
The certification report also suggests that the Oppo PNC110 supports 5G mobile connectivity.
This indicates that the device could support modern cellular networks, although the relevant frequency bands and regional compatibility have not been disclosed.
The chipset remains unidentified.
As a result, there is not enough information to determine whether Oppo is positioning the phone in the budget, mid-range or flagship smartphone segment.
The presence of a large battery does not automatically indicate a high-end processor or premium camera system.
Oppo’s eventual product positioning will depend on the complete specification package and pricing.
