I came over to the 2020 iPhone SE from a 2013 iPhone 5s. So, my perspective might be different from those switching from larger or comparably sized phones. As with all things, there are tradeoffs. But, on balance I'm happy with the SE.
Compared to the iPhone 5s, the SE has many obvious advantages.
- speed
- responsiveness
- solid state TouchID button
- camera quality (the front and rear cameras are both a step up from the 5s, although I will say that the front camera takes much less flattering selfies)
- app compatibility (because the SE uses the full version of iOS 13, while the 5s uses iOS 12 with some features missing)
- cell range (more bands = better LTE coverage, especially inside buildings and in remote areas [I'm on T-Mobile])
- larger screen (this is both an advantage and disadvantage)
- water resistant (my 5s was not watertight, yet somehow survived dunkings in both salt water and pool water; but, it did make headphone detection and charging less reliable afterwards)
- futureproof (my 5s received its most recent update less than 2 months ago but it's now EOL; I used the 5s everyday for over 6 1/2 years, and I would expect the SE to delivery a comparably long shelf life if I choose to keep it for that long)
For me, the disadvantages to the iPhone SE primarily center on the larger form factor. While it remains pocketable and usable with one hand, it's not as EASILY pocketable or usable with one hand.
Without a case, the thinner SE is almost as easy to handle as the 5/5s/SE (2016) bodies with a case. However, while the 2020 SE is built to tighter tolerances and feels great with the rounded edges and glass back, it's also much easier to slip and drop. I dropped my phone 3 times without the case before giving up and using a case with the SE at all times. The glass on the back already has a few scratches but at least nothing shattered.
Some of the common gripes I read about the iPhone SE are not relevant for my use case. So, anyone with concerns about the SE should see which situations are applicable or dealbreakers. And in some cases, what other reviewers insist are disadvantages might not be so for everybody.
Screen Size: I don't use my phone for media consumption. I play games, use the browser on the go, and use the phone for its mobile functionality. I prefer a phone that places more emphasis on the mobility component even at the expense of maximum usability. For how I use the phone, I was already fine with the 4" screen on the 5s. Going even to the 4.7" screen that reviewers regard as tiny nowadays, I found the larger screen to be a tradeoff. I find the utility of one-handed operation comes in handy more frequently than when I would want a larger screen.
Camera: I don't need maximum image quality on my smartphone. My phone is what I use for capturing spontaneous moments and easy sharing. If I want to do higher quality images or compose my shots, I have a DSLR with extra lenses for that. There's no substitute for larger pixels and full-sized lens optics, so I'm okay with less space and expense devoted to the camera function on my phone.
Battery Life: I'm coming over from a 5s, so the battery life on the SE is actually a step up for me. Unless I'm in heavy use, even the 5s had enough battery life for my all-day use. I'm used to charging the phone in the car, or whenever I'm at my work desk. The only time I ever had to keep a watch on the battery level was whenever I traveled, and in those situations I would take steps to conserve battery life (i.e., turn off push notifications, use low power mode, switch to Airplane Mode if I'm in an area or building with bad cell coverage, etc.). The SE has more than enough battery life for how I use the phone, so it's a nonissue in my use case.
Bezels: Coming over from the 5s, I don't have an issue with the look or utility of bezels. I will often grip the phone using the lower edge, so I don't know if going to a full screen would negate being to do that.
Touch ID: Here, I regard the presence of the Touch ID button as an advantage. I keep my phone docked in the car and can unlock the phone without taking my eyes off the road. Using Face ID in the car would not feel safe to me, because it requires positioning my face in front of the screen. Touch ID is at a point where it unlocks the phone almost instantaneously. Pick up the phone, put my thumb on it, and it goes. Maybe it's just what I'm used to, but how can that be viewed as a disadvantage?
Conclusion: So, should you get an iPhone SE? The answer, as with all things tech, is it depends. The SE is basically the iPhone 8s, just as the original 2016 SE was really the iPhone 5gs. It's a refinement to a proven design, at a much lower price. That's how the phone should be viewed.
Because it uses a state-of-the-art processor, anyone who buys the SE will know that the OS and app support will be in place for a long time. Because Apple did not give the SE a numerical designation, it means that they will carry the design forward for multiple years. This is not a model that Apple will replace or update annually. The SE that you buy now is the same one that Apple will likely still be selling two years from now.
The iPhone SE is a combination of best-in-class and older tech. It has to make tradeoffs in order to hit that $400 price point. If the tradeoffs are in areas that are inconsequential to you, then the SE is a no-brainer bargain that you've probably already jumped on. If the SE excludes features or makes design compromises that are more consequential, then that's where you look at the price and determination if the tradeoffs were in more of the right spots than not. If there are things that the SE does that you cannot live with, then it won't matter how low the price is, this phone is not for you.
For me, the SE is a comfortable update to what I've been using. It's not perfect, but I can live with the compromises for what it does actually deliver. And starting at $400, this is the best value in the iOS sphere.
