1. (Further understanding of QC3.0 protocol, contents of old Post may not be valid) Took that power bank apart and looked up the chip number. The chip was little buggy the manufacturer admits, as it outputs 7.3V upon entering QC3.0 continuous mode. It is still in the specs though. I can charge other device because those device observe the voltage and request higher / lower voltage accordingly. It seems like Zenfone 6 does not observe the voltage given by the source supply and requests higher voltage rather blindly (requests 20 times +0.2V from 5V to 9V). Try and change that. This can have extended benefits as some cables which have high resistance lose some voltage, and observing the input voltage at the phones basically compensates for that.
2. The phone cranks down the charging current if CPU/GPU working and heat dissipation is not enough. Perhaps allow the user to set charging to take priority in lighter processor loads, so that the CPU and GPU clocks gets cranked down instead, maintaining the fast charging.
If you don't understand what is happening from my observations, you can comment below
Charging and thermal suggested change
（我第一天知道有ZenFone 6中文論壇，以前在用英文版）
1. 文章第一點和兩個電壓圖其實就是說，有某行動電源進入QC3.0時胡亂出7.3V，手機又不監察USB Vin電壓，老是要求提升4V，不就是出11.3V給手機了嗎？難怪曾經炸手機。如果手機監察Vin來要求更高/更低的電壓，不就是能更快要求電壓（現在+0.2V/2000ms變理論+0.2V/2ms，快1000倍）和應對充電線和接頭的電壓損失，保證盡可能最快充電，和避免不完全合乎QC3.0規格的行動電源弄壞手機。
2. 手機現在優先減少充電電流，不是減CPU速度。在執行一些低CPU要求的負載時，是不理想的。
3. QC3.0時，手機輸入最大13W(9V1.43A)，但是透過誘騙手機進入10W(5V2A)充電模式（電池符號有一個+號），再提高輸入電壓，成功令手機輸入≈17W(9.4V1.8A)。這是軟件bug嗎？不然就太浪費硬件了。
希望這樣能澄清英文版的一些細節。
