Introduction

The Poco X3 Pro - basically the X3N souped up for performance - SD860 (or SD855++) in place of the X3N's SD732G & UFS 3.1 replacing the X3N's decently fast UFS 2.1 (and some material upgrades such as GG6, 2-textured plastic back, & a full verification of the sides' materials - glossy plastic).

Physical features

The X3P is 95% similar to the X3N, so refer to the X3N review for it. The only difference would be on the back panel, as it has a matte finish on the sides of the POCO stripe (which is another component that can be replaced with the X3N's). More details about the backplate in a blogpost

Audio Quality

The X3P has a bottom loudspeaker + earpiece / top speaker stereo combo & a headphone jack.

The speaker quality is very good - the top speaker competes with the top speaker well enough that it doesn't feel drowned out, but it'll also vibrate the back, which you'll feel the most when the X3N's not covered with a case. The back vibration is an unfortunate side effect of using a plastic back.

The headphone jack quality is passable. Loudness wise, it squarely falls into "average" territory.

Display

The 6.67 inch 20:9 120hz LCD with a centered punch hole is mostly the same as the X3N, so refer to the X3N review for it... again. At this point, I'm wondering if I should just merge both X3P & X3N's reviews.

Bootloader unlocking

No changes from the X3N, so it's still the worst bootloader unlock protocol, no questions asked. You need a Xiaomi account, have to submit your phone number to Xiaomi servers, and use a proprietary Windows-only application to unlock its bootloader. That, combined with 168 real-world hours (maybe even more, up to 2 weeks at worst - and yes, it's longer than the F1, as far as I can remember) of wait time (which gets triggered somewhere around the unlocker app as far as I remember), makes it the worst.

Repairability

Repair difficulty on the X3P is basically similar to the X3N - again, the X3P is a souped-up X3N.

Once the panel's heated up & removed, it feels somewhat like the F1, except that 3 of the 4 rear cameras are stuck on the lens & the USB-C port is on the same board as the headphone jack (at least neither are soldered on the main board), forcing a replacement of both if either stops working.

Custom ROM & Kernel Availability (as of 5/2/2022)

The X3P is pretty much a repeat of F1, where it has plenty of ROMs, from decent ones (Arrow, crDroid, Lineage); to complete & utter trash (Ancient, AICP, Derpfest, Nusantara, Octavi, Xperience). All ROMs on the X3P are OSV builds, so the previous list is irrelevant & removed.

For custom kernels that work with OSV builds (which pretty much translates to all of them), here's a list for some of them (at least the ones I've used), as well as their download links :

Other issues

Generally, there's not much problems with the X3P, aside from:

As for avoidable problems, we got :

Conclusion

To cut things short, here's what the X3P are :

Generally, I can somewhat recommend the X3P only if you're fine with Xiaomi's bootloader protocol & the reality of dynamic partitioned PDA hitting at full force (though there's a less convenient workaround). Otherwise, the X3N is a better pick, if you're fine with losing some performance (you get more customizability in return). However, I cannot ignore the elephant in the room on the X3P - random hard-bricking. Be careful if you actually plan on getting it, & make sure you have a solution in case your X3P hard-bricks.

And, as with the X3N, the X3P has 2 hardware variants : Global with NFC (vayu) & Indian without NFC (bhima). The Indian variant might be more prone to hard-bricking due to QC issues so I recommend avoiding it, especially since there's no added battery to replace the missing NFC, unlike the Indian X3.

Regarding rumors of bricked X3s

Source / warning | Testimony sample from Mochi kernel dev

As of 29/10/2021, there are widespread reports of X3s randomly hard-bricking itself from motherboard issues. I personally ignored it as I'm not sure where to post my opinions about it & my X3P hasn't bricked itself yet (MIUI 12.5.5 global firmware; Official ArrowOS 11.0 11/11/2021; 4.14.256 Moonbase Fury kernel 1/12/2021; & repasted with Arctic MX7 at the time of writing - 6/12/2021). However, the fact that a machine hard-bricks itself is a massive concern on its own, & therefore I shouldn't have ignored it (even if I can only somewhat recommend the X3P); & I apologize for it.
