Right now my daughter (Sec 2) is actully not actively using the Poco X6 Pro. She just uses it as a backup phone since she is lazy to transfer the data back from Poco M7 to Poco X6 Pro, even though she says the FPS of some games are very different.
Our main Poco phones -- I will say use them for about two to three years as the main phones and then as a backup if the security updates are still there. If the security updates are gone, maybe only use as test devices.
Me: Poco X7 Pro x 2, not yet using the Poco X8 Pro Max
My wife: iPhone 14 as main, Poco X6 Pro as backup. She may upgrade her iPhone later this year.
My daughter: Poco M7 as main, Poco X6 Pro (repared) as backup.
