Recently, the manager of Xiaomi introduced the application of 100W fast charging technology in mobile phones.
There are five technical difficulties in fast charging technology:
1. Capacity loss: the faster the charging speed, the greater the capacity loss.
According to the preliminary estimate, the capacity loss of the 100W fast charge battery is about 20% more than that of the 30W PD fast charge, that is, the 5000mAh is turned into 4000mAh.
2. Technical implementation (technical architecture): ultra-high voltage charging scheme.
3. Performance: how to make 100W charging not only technically accessible but also long-lasting and sustainable.
4. Safety: multiple protections for the motherboard, battery, charger, etc.
5. Various charging methods: supports both wired charging and wireless charging, while their charger is compatible.
On the whole, 100W fast charging technology gets mature enough in the early stage of mass production, but it is still not enough. Considering that the overall power consumption of 5G smartphones is still much higher than that of 4G, especially in the full coverage of the 5G network, power consumption is much faster. And how to balance the fast charge with the battery capacity loss is the focus consideration of everyone.
So will you choose the battery of 30W PD charging + 5000mAh or 100W charging + 4000mAh?
Netizens: I will choose 65W fast charge + 5000mAh for the price!
From the previous test of OPPO Reno Ace, the current 65W wired fast charge is already high-speed, it’s a milestone compared to the last 30W/40W fast charging.
To compare the smartphones of 4000mAh and 5000mAh battery, in addition to considering the battery capacity itself, we should also regard the weight of the smartphones. As we know, the battery life of a large battery is more long-lasting. Still, if it makes the smartphone weigh more than 230g, then it will also bring a very uncomfortable and inconvenient experience for us daily.
In the first half of this year, the combination of 4500mAh battery and 65W fast charging should be an ideal one.
So, when will the 100W fast charging put into the production of Xiaomi smartphones?
According to the revealing, Xiaomi has confirmed that the 100W wired fast charge will get into commercial use this year. From the roll-out schedule of Xiaomi’s new phones in the past years, the 100W fast charging is more likely to be launched with Xiaomi Mi MIX 4 in the second half of 2020. Are you looking forward to it?
So, which combination of the smartphone will you prefer?
