Mate 9:

It includes a feature that enables the device to learn about the habits of its user and automatically put the most frequently used apps in easy reach

“It learns how you use your phone,” said Arne Herkelmann, Huawei’s European head of handset portfolio and planning.

The algorithm puts the user’s favorite apps first, which makes the phones easier to use and also more energy-efficient.

“Just the device is no longer enough,” said Roberta Cozza, an analyst at research firm Gartner. “AI and voice control will be main features on smartphones in the coming years.”

"You won’t notice the performance-enhancing machine-learning algorithm at work -- and that’s a good thing." - Engagdet says in its review, but fails to explain anything at all about it in the body other than "The Mate 9’s machine-learning algorithm prioritizes resources to apps that it anticipates you’ll use, making your overall experience smoother"

"The Huawei Mate 9 automatically learns user habits to build app priority. The system anticipates the user’s next moves to prepare resources in advance.
This process is run on the phone, not the cloud for better performance and privacy protection."

"The Huawei Mate 9 automatically manages resources by prioritizing CPU, RAM and ROM for optimal performance and closes memory intensive background apps. Within the CPU, fine-grained scheduling maximizes computing efficiency. For RAM, it automatically recycles memory resources, creating more memory for priority apps and enabling stutter-free performance. And for ROM, it opens an exclusive channel of Storage I/O making the apps you use the most work even faster." --> Complete bullshit

"The new F2FS file system improves the I/O storage performance. This speeds up the database engine allowing pictures to load more smoothly. The optimized performance of the rendering engine gives better control and a faster reaction to your touch." <--- These are the real engines behind faster performance. F2FS on UFS 2.1, plus the rendering changes (similar to Android 7.1's)

Honor Magic:

"It’s the first Honor device with AI-driven features which allow the phone to serve up contextually aware content"

" pull up shipping information for a package you are expecting when you go to the post office, show train and flight times for a trip you have in your calendar or pull up your shopping list while at the grocery store"

"If you buy a train ticket and step into a train station, or buy a movie ticket and step into the movie theater, your ticket pops up. Thanks to Honor's integration with various partners, it can combine your GPS data with its knowledge about the purpose of certain locations to push out information proactively.

In the future, the phone may store and recognize your habits. For instance, I listen to news radio every morning when doing the dishes. So the Magic might suggest turning on 1010 WINS at the habitual time, Honor reps said."

" The one feature Honor could show me is that in a dark room, a flashlight icon pops up."

U Ultra:

"present you with priority notifications and alerts based on people [who] you contact the most"

"HTC AI will be able to understand your consumption patterns as well. For instance, rather than simply recommending restaurants around you, it will learn how you order food - based on restaurant ratings and proximity - and over time, when it’s gathered enough data, it will offer prompts to the places you are most likely to order from. The same goes for the weather. Instead of alerting you with weather alerts every day or hour, Sense Companion will only alert you when the weather is unusual. At launch, Sense Companion is said to work with only some of the core HTC apps, with more to follow in the coming months."

" adding your favourite contacts and apps in order to “train” the AI, after which it’s supposed to automatically manage this for you. One scenario that was presented to us was that the AI will be able to alert you if your phone needs a charge, depending on your schedule for the day"

"HTC claims it has a "different philosophy" on AI, which in this case means it isn't going for a full virtual assistant but instead little bits of extra intelligence in a variety of apps."

"give you recommendations based on your phone usage, highlight which contacts are most important to you and make tweaks to improve the software experience. For example notifications can be prioritized based on your favorite contacts, apps will be managed based on what you use most, and the phone can tweak battery management if it knows you won't make it through the day at your current usage."

"By its own admission HTC says you won't see immediate impact from the artificial intelligence, as it takes time to learn your habits and figure out how to help you best."
