OPPO is scheduled to officially launch its new product – the OPPO R15 on March 31. The phone boasts of dual-surface glass body and it features a 6.28-inch Super-V Display with aspect ratio of 19:9. Today, we will start the teardown of the R15 to explore its internal structure.
First of all, remove the SIM card tray.
Use a sucker to separate the back cover from phone body. When removing back cover, avoid getting glass broken and disconnecting fingerprint cable since it is connected with the back cover.
The phone still adopts three-stage internal design. We find no visible cable connector since all of them are fixed by metal holders.
We need to disconnect the battery connector first. Remove screws which are used to fix cover plate after finding battery connector.
There is only fingerprint reader module on the back cover. This module is fully sealed. How to remove old fingerprint reader and install new one once the back cover gets broken is a problem. Fingerprint reader is surrounded with lots of foams. Besides, the motherboard area features graphite sticker.
This is dual-rear camera setup. It is evident that the main camera with F/1.7 aperture is bigger than auxiliary camera with F/2.2 aperture. The dual cameras don’t support optical zoom function.
The phone features a 20MP front camera with F/2.0 aperture.
As for space utilization, the front of the motherboard has compact design except connectors occupy much space. Uncover graphite sticker on the shield cover, we find metal sticker under it. Both graphite sticker and metal sticker are used to help heat dissipation to prevent some parts gathering too much heat.
Continue to uncover metal heat dissipation layer, and we find that shield cover is weld tightly on the motherboard. As a result, the shield cover fails to be removed from the motherboard. Only a chip which is covered by conductive silicone can be seen.
The shield cover on the back of the motherboard is still covered by graphite sticker and metal sticker. Two core big chips are covered by conductive grease.
The R15 is powered by 2.0GHz octa-core Helio P60 processor. It features a 128GB ROM – KM3V6001CM B705 from Samsung. We infer that 6GB RAM is sealed together with the ROM.
Under the motherboard, we can see that buttons on two sides and top sensor are connected to the motherboard via metal contact. Such design can effectively utilize space on the back of the motherboard. Besides, edge parts get thickened. It is surprising to see that a sensor gets piled together with the earphone.
Uncover the tape on the right side of the battery, and then take out the battery.
The battery reads DVT trial-produce battery. The R15 sports a high-cost 3450mAh Li-ion battery. Its limited charge voltage is 4.4V and normal voltage is 3.85V. Another OPPO R15 version sports a 3400mAh battery.
Take out PCB at the bottom. We find that pick-up microphone is designed on the PCB. Therefore, the phone’s right side at the bottom is in charge of recording sound while the other side is in charge of playing sound.
After taking out the loudspeaker module, we find its supplier is ACC.
In the end, take out the earphone with independent design. Until now, our teardown work is finished.
In general, the OPPO R15 is a good-quality product that consumer can trust. By designing roll cage and middle framework as an entirety, OPPO has improved the phone’s resistance to pressure. It has excellent heat dissipation design and good sealing method. The phone boasts of specification which can meet consumer’s demand. The phone’s battery, loudspeaker and glass cover are high-end products from top manufacturers.
