the baseband is integrated into the soc, and a 4-in-1 (Bluetooth, wifi,gps,fm) and 5-in-1 wireless chip is made, and the audio is integrated into the power management chip. This requires a lot of skill. The space of the mobile phone is so large, the integration takes up less space, more batteries can be put in, and the heat can be dissipated more effectively. Mobile phone manufacturers can also reduce research and development costs.
take mx3 and mx4 as examples. Mx4 has 8 mA more battery power than mx3, but the area is not much larger. From the cloth board, mx3 is a double-sided pcb board, and mx4 is probably a single-sided PCB board. Not only the thickness is reduced, but also the heat dissipation is obviously improved. Due to the adoption of a complete set of programs, many models can be produced in a year to seize the market, and the signal is also very guaranteed.
why Meizu doesn't adopt the Qualcomm plan. Maybe it's the patent fee, or maybe it can't be a preferred supplier. As we all know, Xiaomi and Qualcomm have a good relationship.
2. Besides, MediaTek MediaTek feels like a tragedy. In the 2g era, the relationship between mobile phones and suppliers is relatively stable. Ti and Nokia, motorcycles and Falcons. MediaTek was turned away from Nokia, so he had to become an outlaw. In the era of smart phones, MediaTek also had a bad time. Support vivo to engage in hifi music mobile phones (because the sound quality of cpu in Qualcomm was very poor at that time), and vivo went to Qualcomm after it became a hit. Xiaomi used his cpu to make Redmi, which became an instant hit, and the order was tens of millions. Later, Red Rice 2 used Qualcomm cpu, leaving MediaTek with a low-end bad reputation. Huawei Hisilicon's k3v2 has a bad reputation, poor endurance and serious fever. Huawei used mt6582 to get a glory 3c, and the power consumption control was excellent and sold well. As a result, the 4g version of glory 3c was replaced by the processor of Hisilicon, and now the power consumption has become the selling point of Huawei's mobile phone. MediaTek just made others red and left a pile of shit for himself.
Therefore, I think there is still a lot to watch about the cooperation between Meizu and MediaTek. Meizu can solve the problem of heating signal and provide stable supply. MediaTek will not become a tool for others to use. Xiaomi couldn't get the best cpu in Qualcomm for the first time. The best things in Qualcomm must be supplied to Samsung and htc first. No one will give Xiaomi their own good things for futures and ruin their reputation. This is probably the most dangerous thing for Xiaomi now.
