OPPO R15 Teardown

OPPO is scheduled to launch the OPPO R15 on March 31. The phone adopts a dual glass body design and features a 6.28-inch Super-V display with a 19:9 screen ratio. Today, we will disassemble the R15 to explore its internal structure.

First, remove the SIM card tray.

Use a suction cup to separate the back cover from the phone body. When removing the back cover, avoid breaking the glass and be careful not to damage the fingerprint cable connected to the back cover.

The internal structure of this phone still uses a three-segment design. We did not find any visible connectors, as all connectors are secured via metal plates.

We need to disconnect the battery connector first. Remove the screws securing the metal plate after finding the battery connector.

There is only one fingerprint recognition module on the back cover, and it is completely sealed. Once the back cover is broken, it is difficult to remove the old fingerprint reader, and installing a new one is also challenging. The fingerprint reader is surrounded by foam, and there is a graphite sticker on the corresponding area of the motherboard.

This is a dual rear camera setup. The main camera features an F/1.7 aperture, which is significantly larger than the auxiliary camera’s F/2.2 aperture. The dual cameras do not support optical zoom functionality.

The phone features a 20MP front camera with an F/2.0 aperture.

The front of the motherboard features a compact design, but the connector area takes up a relatively large space. After removing the graphite sticker on the metal shield, a metal heat dissipation layer underneath can be seen. The graphite sticker and metal heat dissipation layer work together to dissipate heat, preventing some components from gathering too much heat.

Continuing to remove the metal heat dissipation layer, we found that the metal shield is soldered onto the motherboard. Therefore, the metal shield cannot be removed from the motherboard, and only the chip covered by thermal grease is visible.

The metal shields on the back of the motherboard are still covered by graphite stickers. Two big core chips are covered by thermal grease.

The R15 is powered by a 2.0GHz octa-core Helio P60 processor. It features a 128GB ROM (Samsung KM3V6001CM B705). We speculated that the 6GB RAM is sealed together with the ROM.

Under the motherboard, we can see that the buttons on the two sides and the top sensor are connected to the motherboard via the metal contacts. This design makes efficient use of the space on the back of the motherboard. In addition, the edges have been reinforced. It is surprising to see that a sensor gets stacked together with the earphones.

Uncover the tape on the right side of the battery, and then take out the battery.

The battery is labeled as a DVT trial production battery. The R15 features a 3450mAh Li-ion battery, with a maximum charging voltage of 4.4V and a normal voltage of 3.85V. Another variant of the OPPO R15 comes with a 3400mAh battery.

Remove the PCB board at the bottom. We found that the microphone is designed on the PCB board. Therefore, the right side at the bottom of the phone is responsible for recording, while the other side is responsible for playing sound.

After taking out the loudspeaker module, we find its supplier is ACC.

In the end, take out the headphone jack module. Until now, our teardown is complete.

Summary
Overall, the OPPO R15 is a high-quality product that consumers can trust. By designing the roll cage and middle framework as an entirety, OPPO has significantly improved the phone’s pressure resistance. It has an excellent heat dissipation design and a good sealing method, and the specifications are sufficient to meet consumer needs. The battery, speakers, and glass cover are high-end products from leading manufacturers.
