Although Snapdragon 810 chip, which is inside many of todays flagships including ZTE Nubia Z9 Max, is really powerful, there have been a lot of talks that it has overheating issues. One of the solutions here is to reduce the power of the chip as the HTC did with its flagship M9. They managed to solve the heating issue, but they they did with a significant loss of performance.
After the Numbia Z9 Max was released, it was put through some heat tests and it managed to do a bit better, which equals to the 42 degrees of the shell temperature. It is quite warm, but still acceptable compared to HTC One M9 45-50 ℃.
Besides regular points, this teardown will focus on the Snapdragon chip issues and what Nubia did with its Z9 Max to overcome overheating issues.
First of all, in addition to the metal shield protection of the chip, there is also a large area of graphite thermal layer, a metal synthetic coatings and some other protection layers to reduce the heat exposed to the shell of the device and, probably, the temperature of the chip itself.
Besides the chip, the teardown reveals that the device uses Samsung LPDDR4 3GB memory chips. Also, the flash memory is Samsung eMMC 5.0. What is more, there is a battery along with the proprietary charging mechanism, which has charging voltage of 4.4V, 3.84V operating voltage and the energy density of 70Wh / L.
Overall, the ZTE Nubia Z9 Max is really well made both inside and out. Everything under the hood is neatly placed and it shows a great workmanship. This device definitely shapes up to be one of the better offerings in 2015.
