I want to buy a new mobile phone but I can't decide between 2 devices - Pocophone F1 and Mi Mix 2S. The problem is that I can't find reliable specifications of these mobile phones.
Both mobile phones have Qualcomm Snapdragon 845 so they should have the same mobile network features/specifications. But that's the problem, they don't have.
Here are official specifications for Poco F1:

Unfortunately, no additional information is published anywhere and these below are directly from Qualcomm webpage. I don't know if Xiaomi has changed them. Those that are marked in red are very important to me and I can't find them for Poco F1:
Downlink LTE Category: LTE Category 18 (downlink)
Uplink LTE Category: LTE Category 13 (uplink)
LTE Downlink Features
Downlink Carrier Aggregation: 5x20 MHz carrier aggregation
Downlink LTE MIMO: Up to 4x4 MIMO on three carriers
Downlink LTE Streams: Maximum 12 spatial streams
Downlink QAM: Up to 256-QAM
LTE Uplink Features
Uplink Carrier Aggregation: 2x20 MHz carrier aggregation
Uplink QAM: Up to 64-QAM
On the other hand, we have a Mi Mix 2S. Here are basic informations for this mobile phone:

The problem is that in the last sentence it is stated that MIMO 4x4 only works in the B41 band. That's strange, of course, because I haven't seen a limitation on MIMO per band in my life and I haven't heard about it. Does this mean that the Poco F1 also has this limitation? If not, why does Mi Mix 2S have this limitation when the Poco F1 has the same CPU type?
In addition, Poco F1 is reported to have LTE-A (4CA) Cat16 1024/150 Mbps, and Mi Mix 2S features LTE-A (3CA) Cat18 1200/100 Mbps. How is it possible that mobiles with the same CPU, that means they must have the same radio, have different specifications? Qualcomm stated on the site that it is an LTE Cat18. Why does Poco F1 have a different specification?
So can anyone provide me with complete and detailed specifications?
