Best OnePlus 9 Pro thin case: Spigen Liquid Air Armor

OnePlus 9 Pro Spigen Liquid Air Armor
Keep your phone safe without packing on thickness or weight with this thin and light case from Spigen.

Pros:

  • Thin and light
  • Tactile button covers
  • Anti-slip matte surface

Cons:

  • Only one color option (black)

The Liquid Air Armor may not be the thinnest case in Spigen’s arsenal but is more protective than its other options. It’s a flexible TPU case with a soft bumper that makes it easy to install and remove. A ridged pattern on the back and sides and an anti-slip matte finish add to the grip, and a raised lip keeps the display and rear camera safe. For protection without bulk, the Spigen Liquid Air Armor is the case to get.

OnePlus 9 Pro Double-N wallet
This wallet case comes with four slots for credit cards or ID and a pocket for cash. The folio cover can be folded into a kickstand, and it also comes with a wrist strap.

Pros:

  • Can hold up to four cards and cash
  • Folio cover doubles as a kickstand
  • Multiple color options
  • Comes with a wrist strap

Cons:

The magnetic closure keeps the front cover firmly closed, and the folio cover can be used as a kickstand. You have a few color options to choose from, like black, blue, green, pink, and red. You can store up to four cards and some cash.


Best OnePlus 9 Pro rugged case: Spigen Tough Armor

Rugged protection without too much bulk is what you get with the Tough Armor. The dual-layer case comes with a thick TPU bumper case and a hardshell frame, and it also has a built-in kickstand to prop the phone up in the landscape orientation.

Pros:

  • Good protection without too much bulk
  • Mil-grade certified
  • Built-in kickstand

Cons:

  • Flimsy plastic kickstand

The Tough Armor is Spigen’s rugged offering and one of the best cases you can get. A layer of soft TPU helps with shock absorption, and a polycarbonate shell keeps scratches at bay. It even packs a built-in kickstand. The kickstand is a little flimsy, though. It works as expected, but its durability is a concern, especially with a relatively heavy phone like the OnePlus 9 Pro.

How we test phone cases

We rigorously test smartphones, accessories, and other products in our reviews here at Android Authority. There are plenty of factors we consider before choosing the best OnePlus 9 Pro cases currently available.

  • Protection: An ultra-thin case is great to keep the phone scratch-free but isn’t helpful in case of bumps and drops. We simulate real-world drops to test durability for hybrid and rugged cases, like if the phone falls while pulling it out of the pocket or if it slips off of a table. We also consider corner protection, the lip around the display and rear camera, and whether the buttons are covered.
  • Build materials and quality: A bad case could do more harm to your phone than good. Poor-quality polycarbonate cases can break when installing or removing them. If you have to apply a lot of pressure to remove a case, the case might crack. With softer TPU cases, continuously removing the case might cause it to loosen around the corners, affecting the fit and protection.
  • Grip: Along with hands-on testing, we slide the phone across different surfaces like wood and marble to see whether it is slippery. Cases get extra points if they have ridges or bumps to help with the grip.
  • Installation and removal: Installing a case shouldn’t be difficult, and we don’t feature cases that can’t even be installed easily. However, removing a case can be a pain with high-quality cases and potentially damage your phone. It’s a big no-no if you have to apply a lot of force to the point where you feel the phone almost bending.
  • Design and colorways: Design and color are personal choices, but it’s nice to have options. We also have a dedicated category for clear cases to show off the phone’s design.
  • Price: You don’t have to spend too much to get a good case. $10 cases that offer as much protection, if not more, than $50 options.
