OnePlus 15 Disassembly Major Developments and Downgrades
A detailed breakdown has been done on the new OnePlus 15, confirming a drastic change in the flagship's internal design, which is thus marked by a trade-off between battery lifeline and camera performance. The analysis of the device, which was led by Chinese blogger WekiHome, shows that while the battery and cooling systems have developed, the camera hardware within is clearly worse than its predecessor, the OnePlus 13.
Key Improvements Battery and Cooling
The teardown includes several important improvements based on performance, longevity and the like:
- Enormous Battery: The most noticeable change is the massive dual-section 7300 mAh silicon-carbon battery. This is a great improvement from the previous 6000 mAh battery of the OnePlus 13.
- Enhanced Cooling System: The OnePlus 15 is equipped with a larger steel vapor chamber measuring 5700 mm², compared to 4700 mm² for the previous model. This should further enhance efficiency in dissipating heat while carrying out tasks such as gaming.
- Better Audio: The top speaker has been enlarged and is expected to produce a clearer and more balanced stereo sound.
The price Weaker Camera System
Most of these improvements were made at the expense of the photographic capabilities of the phone. The teardown confirmed several downgrades:
- Smaller Sensors and Narrower Apertures: All rear camera sensors are replaced with physically smaller versions with narrower apertures, although maintaining the same megapixel count. Change changes will, however, adversely affect how much light gets in overall quality of images.
- The End of Hasselblad Partnership: This model ends the partnership with the camera manufacturer Hasselblad.
- Fewer Microphones: The number of microphones has reduced from four in the previous models to three. The openings of the microphones are longer to avoid confusion with the SIM card slot.
Summary of Changes
Redesign inside the OnePlus 15. This indicates a strategic move by the company to keep a much bigger battery and greatly improved thermal management capabilities-most likely targeted at power users and gamers. Yet this is matched with a clear and confirmed degradation of the rear camera system, which may disappoint photography enthusiasts who would have benefitted from the functions of the previous flagship.
