The Best Phones Under $400

What you no longer give up

Performance is a solved problem in this bracket. Every phone we tested under $400 opened apps, scrolled social feeds and ran video calls without stutter, and the gap to a flagship in everyday use is now essentially invisible.

Screens have caught up too. 90 or 120 Hz OLED panels are standard, and while peak brightness is lower - typically 800 to 1200 nits versus 2000-plus - that only matters in direct summer sun.

Build quality is fine. Plastic backs are more repairable than glass and considerably less likely to shatter, and most of these phones now carry a real IP rating.

What you still give up

Cameras, in low light. A $350 phone takes photos indistinguishable from a flagship in daylight and falls apart the moment the sun goes down, because the sensor is smaller and the computational stack is less sophisticated. If you photograph a lot of restaurants, concerts or children indoors, this is where your money goes.

Software support is the second gap and it is closing unevenly. Some manufacturers now offer five years of security patches on a $350 phone while others offer two years on a $900 one - see our Mirador Flux 9 review for how badly that can go.

Charging speed, wireless charging and haptics are the small things. The vibration motor on a cheap phone feels like a buzzer rather than a tap, and you will notice it every time you type.

Buy the support window, not the spec sheet.

Our pick: Aster Nine, $329

The Aster Nine gets the important things right: a 5000 mAh battery that comfortably clears seven hours of screen time, a 120 Hz OLED, and five years of security updates announced at launch and written into the spec sheet.

The camera is the expected story - good in daylight, mediocre after dark - and the ultrawide is a formality. But there is no bloatware, the charger is included, and the bootloader is unlockable if that matters to you.

At $329 it is the phone we recommend to family members who want to stop thinking about phones.

The runner-up and the trap

The runner-up at $379 has a better main camera and a noticeably nicer screen, and gives up two years of update support to get there. That is a bad trade at any price and a worse one at the bottom of the market, where people keep phones longest.

The trap in this bracket is the heavily discounted last-generation flagship. A two-year-old $900 phone selling for $380 looks like a bargain until you check how many years of security updates remain on it. Often the answer is one.

Buy the support window, not the spec sheet.

How to check before you buy

Find the manufacturer's published update policy and the phone's launch date. Subtract. If the answer is less than four years of remaining security patches, treat the phone as disposable and price it accordingly.

Check whether the charger is included. A $329 phone plus a $45 charger is a $374 phone.

Finally, check the band support for your carrier, especially if you are importing. A phone that cannot see your carrier's mid-band 5G is a phone with a permanently worse connection than the one you have now.
