ZTE's $99 ZMax Pro packs in some of the latest smartphone technologies, something you wouldn't expect in a low-priced handset.
The smartphone has a 6-in. screen and is available only through MetroPCS in the U.S. It weighs about 175 grams and is 8.9 millimeters thick.
It has some top-line features found in the latest smartphones, like a USB Type-C port. It also runs on the latest Android OS 6.0 code-named Marshmallow.
The Gorilla Glass 3 screen shows images at a full HD resolution. The handset has 32GB of internal storage and a micro-SD card for expandable storage. That's a lot of storage for a handset under $100.
The handset is comparable to the new fourth-generation Moto G handset, which is now available unlocked on Amazon.com for $199.99 for a 16GB model. The Zmax Pro has a 13-megapixel rear camera and 5-megapixel front camera, along with an eight-core Snapdragon 617 processor, all of which are also packaged in the Moto G.
[...] However, the smartphone lacks some other features. It includes 802.11 b/g/n Wi-Fi, not the latest 802.11ac, which offers a wider range and faster speeds.

I was impressed by the 3.4AH battery: until I realized that it has a USB type C port.
Power=Current*Voltage
100W/3.6V=27.8A
3.4AH/27.8A=0.12239H run-time -> 7minute, 20 second run-time.

The USB-C port doesn't have to use 100W, and probably can't. [androidauthority.com]
For devices making use of USB Power Delivery, communication is exchanged over the connector’s CC pin, which was introduced with the new 2.0 standard. This communication configures the right power between the charger and device, allowing for up to 100W of power at its most extreme, using up to 20 volts and 5 amps of current. This mode is most likely to be used by laptops and other more power hungry devices, as it supports higher voltage modes.
A handshake between micro-controllers overwrites all of the lower power modes and sets up the correct voltage and current settings, while no handshake means that these higher power modes can’t be activated. This also means that lower power use cases, such as smartphones, can be covered without this extra technological cost.

From TFA (so take it with a grain of salt):
The ZTE phone also has a 3,400 milli-amp-hour battery, which provides about 25 hours of talk time and 400 hours of standby time.

Your math as well as your understanding of everything you are referring to is all wrong.
Is your first bit of math implying a 100W power drain or charge of the battery? I can't tell. The second bit looks like you confused run time with charging time for a 100W charge mode. I doubt that little li-po in the phone will be happy with a 27.8A charge current.
The new USB C standard includes a 20 volt/5A power option to deliver 100W. It does not mean that battery/phone is forced to charge at 100W. That is simply what you can draw at a maximum.
The amp/hour rating of a battery is the rate of discharge the battery can accommodate for an hour without a significant drop in voltage or current. Meaning, a 10V 10AH battery should be able to deliver 10A@10V (or 100W) for one whole hour before voltage starts to drop off.

I was talking discharge current. I have an anti-USB-Type-C bias.
I stand corrected if small USB devices are not required to supply 20V.
My experience with older USB devices is that few of them actually properly negotiate power draw.

OK, I understand the confusion now: most phones do not act as a USB host.

Nevermind, USB type C is reversible,
