1. Yes, you get a very long battery life but only until the next Android version comes out. Had this with a few of their "Power" models. Each update reduces the SOT by ~20-30%
2. Build quality is good but the same can be said about many other competitors.
3. Their displays are okay, they used to have Samsung Super AMOLED panels on some of their devices but now they're buying from China.
The real reasons why people pick Motorola is good call quality (Most of them have great mics with efficient noise canceling), the OS isn't bloated and full of ads, it's closer to stock Android with some Moto additions, and the Moto gestures are very practical and many really get used to them.
I'm disappointed that this phone is running on the efficient Dimensity 7300 and manages to get very warm and also in the UFS 2.2 memory, why not UFS 3.1?
