I recommend turning off push notifications, however, as DJI has unfortunately opted to use Mimo as a delivery system for product announcement and sale notifications. I hate seeing ads on my phone's screen, and camera apps shouldn't add to the noise. The Osmo Action 3's battery gets about 75 minutes of record time at 4K60, a very good result for an action cam. What's better is that it manages to go that long without overheating—during our battery run-down test, the screen turned itself off about 55 minutes and warned that the camera was hot, but continued to roll until the battery exhausted about 20 minutes later. Stills photography is only 12 megapixels in a choice of Wide or Standard (Dwarp), but Raw files are an option as is manual control over exposure, either by choosing an EV target or explicitly setting shutter and ISO. The aperture is fixed at ƒ/2.8 which means any subject beyond 300mm (12 inches) should be in focus. Tested in a -20° C (-4° F) laboratory environment while recording 1080p/30fps video with EIS disabled and both screens off, and should be used for reference only.

The other place the Osmo Action 3 impresses is battery life. DJI claims 160 minutes at 1080p. I only managed 140 (with the rear screen off, the front screen used about half that time), which is slightly more than I managed with the GoPro Hero11 (which claims 137 minutes, I got 124 minutes). Moving to 4K at 30fps, the Osmo Action pulled off 75 minutes to the GoPro Hero11’s 70 minutes. Also impressive is the recharge time—I was able to get the batteries fully recharged in 52 minutes. Interestingly, Osmo Action 3 is the first action camera with dual touchscreens, which means you can access settings from any angle while keeping the camera in perfect position. The above video hasn't been edited in the DJI Mimo app, but you can edit footage there if you wish. I found the app's editing suite adequate; it does the basics well, but I wouldn't mind some more editing options. There is an AI editor that, in theory, could help you create social media-worthy clips of multiple videos, but in my experience, it struggles a bit to make sense of what's happening in the footage.The customizability options extend to the product’s design, which features a modern and expanded colour range in addition to an iincreased positioning offer.

The dual screens offer the same options presented to suit the display size. (Image credit: Adam Juniper / Digital Camera World)Where the DJI Action 2 dropped the ball was heat management. Its small body and exposed metal design resulted in uncomfortably hot temperatures after even short bouts of recording high-resolution content. This time, though, DJI has improved things significantly. Currently, only English and Mandarin Chinese are supported for this function. Please use it in quiet environments and ensure clear and accurate pronunciation.
