IPhone X Wifi keep disconnecting while leave for 10-30 seconds in lockscreen after latest 12.1.12 update yesterday

Suddenly my Iphone X keeps on dropping wifi connection after leave idle for 10-30 seconds, but it immediately connected again after I picked it up. I already try various workaround because I haven't find anything from the apple support. From reset network settings, renew lease, forget wifi, hard restart, turning on off battery saving, still no result. Battery are at 70-80% and also I already tried connect it to a power source, still no result.

Any help on this ? Thanks in advance !

It's not "suddenly". Every iPhone ever made (1.2 billion of them) since the beginning of iPhone time 11 years ago has disconnected from Wi-Fi when the screen locks unless it is connected to power. It does this to preserve battery life, because Wi-Fi uses power continuously when connected whether transferring data or not.

That is odd. Really sorry of how less of some knowledge I am. But last weekend before the last updates everytime I look up the phone, it never shows the data signal which is the LTE icons but now it shows it first and then the wifi icons pop out. Sure, I got no prove of it and it is just some remembering. Nonetheless, thank you.
