The biggest setback of this camera, however, is indoor performance. As soon as you start relying on limited indoor lighting, the quality starts getting blurry and soft. The downgrade in quality may not be noticeable on a small screen but once you blow it up on a bigger display, you'll understand what I mean. Is it a big deal if the sole reason you're getting the F3 is basically for the performance, probably not. But if you're a camera-centric user who prioritizes picture quality above else, you might be better off with a slightly worse performance but with better optics like a Samsung Galaxy A52 with OIS, or something similar.
Although other brands also deal with this kind of problem, it's not as often as Xiaomi phones. The worst issue that I had with a Xiaomi device is that the screen turned green for no reason, and I just got lucky that it was fixed with a press of the power button. I'm not saying that it'll happen to you but it's never too late to know a few things in advance before splurging for something as expensive as the F3. The third reason why POCO F3 isn't for you is the battery. By today's standards, 4500mAh is the sweet spot between battery longevity and a lightweight phone.
But when you have a large 120Hz display and a powerful Snapdragon 870 to support for at least 15 hours every single day, that might be asking too much. For a regular user like me who spends at least an hour on the phone playing games and at least three hours of streaming and procrastination, the F3 can easily last me a whole day. But given the capability of the F3 to push apps and games to their utmost graphical setting, don't expect the F3 to last you before dinner time if you intend to use this phone at high performance for an extended period. While you have the option to switch back to 60Hz to save a bit of battery, why would you even when the fast display is one of the best features of the device? Either way, F3 is a powerful phone that zips through the battery fast when not kept in check. The fourth reason why POCO F3 isn't for you is the extras (or lack thereof).
I thought Xiaomi would be one of the few companies that would not be swayed by trends, but to my surprised, they omitted two key features that most enthusiasts and fans cherish -- the headphone jack and the microSD slot. There's no option to expand storage with the F3, so you need to make do with either 128 or 256GB. In 2021, 128 is slowly becoming limiting. And while Xiaomi was kind enough to include an adapter in the box to let you use your wired headphones, it's still not as convenient as having one built into the phone, just waiting for you to plug in the jack. The last reason why POCO F3 isn't for you is if you already own a flagship or a high-end phone.
It's definitely tempting to get the F3 given the package it offers, such as a fast AMOLED screen, near top-of-the-line performance, and a thin & light design that can easily turn heads in public. But as much as we want to praise Xiaomi for its efforts to provide an affordable top-end user experience, the F3 still falls short compared to older top models like Samsung's Galaxy Note 9, which was considered the best smartphone of three years ago. When I compare them side-by-side, the Galaxy Note 9 still has the better display quality despite the lack of a fast refresh, the better build quality despite the smudgy back panel, the more complete package thanks to the headphone jack, MicroSD slot, and its S-pen, the better stereo speaker quality, and the better cameras despite using a three-year-old 12MP sensor. What I'm basically saying is that the F3 doesn't guarantee a full upgrade if one is coming from the likes of the Galaxy Note of the world. Even if you are coming from a POCO F2 Pro, that's still a good phone today.
I think you need to be at least on the POCO F1 to consider getting the F3. If these reasons don't bother you at all, by all means, the POCO F3 maybe your next phone. But that's about it for my top reasons why the F3 isn't for you. As always, drop a sub or a like if you feel supporting the channel. And until the next one, stay safe.
