OM-D E-M1X Battery Life Test

As part of my ongoing evaluation of some Olympus Loaner Gear I went out yesterday to conduct an OM-D E-M1X battery life test. During other field tests I have been surprised with the battery life in the OM-D E-M1X. So, I decided it was time to spend some time doing a battery life test.

NOTE: Click on images to enlarge. I have included a few images from my OM-D E-M1X battery test to serve as visual breaks.

As we all know, battery life can vary quite a bit based on photographic style and content, weather conditions, and the use of a camera’s rear screen.

To put my OM-D E-M1X battery life test in context it is important to specify the type of photography I was doing and the weather conditions.

It was a fairly bright sunny day with the temperature in the 20 degree Celcius range (68 degrees Fahrenheit). I was photographing mainly swallows in flight using Sequential Low, i.e. 10 frames-per-second using the mechanical shutter. I used Continuous Auto-focus with a 5×5 AF pattern. My camera was set to Manual Mode with an auto-ISO setting.

I had the rear screen flipped around and visible so I could look at the back of the camera quickly. I checked my images periodically, but spent most of my time photographing the swallows.

I set the OM-D E-M1X for ‘quick sleep mode’. Given how fast I was photographing the swallows I don’t know how often the camera had the opportunity to actually go into this mode.

I had about 2 hours to do this test. My goal was to fill two 32 GB cards within that time frame. I was able to meet my objective and filled two 32 GB cards with a total of 2,710 images. I was shooting in RAW + jpeg.

At the conclusion of my OM-D E-M1X battery life test the camera was reporting 46% battery life remaining. On the surface this was very impressive… but this was the amount of battery life remaining on Battery 1 only. Battery 2 still had 100% charge!

Over the past several weeks I have routinely been able to capture well over 2,000 images on only 1 of the E-M1X’s 2 batteries. This was the first time I went out to actually measure battery life on the camera. My OM-D E-M1X battery life test confirmed that this camera has excellent battery life in typical, real world use.

For readers who have some experience photographing swallows in flight, you may find the subject distances noted in the EXIF data of interest. This speaks to the quick auto-focusing performance of the Olympus OM-D E-M1X. I did not use Subject Tracking.

All photographs in this article were captured using camera gear as noted in the EXIF data. All of the photographs displayed in this article were produced from RAW files using my standard process.

    1. The Olympus OM-D E-M1X displays the percentage amount of battery life left by battery number. Once battery 1 is depleted the camera will then show the amount of life left on battery 2. There are various battery settings that can be set in terms of sleep mode etc.

  1. Hi Thomas,
    The E-M1X is an amazing camera. I too had a loaner from Olympus with the aim of testing Procapture and the AF system. Super sharp (using Oly 12-40/f2.8 Pro). However, I was astounded with the battery life. I took around 3,500 photos and the battery life was still 51% (first battery only!). I maximised battery life by not using the lcd screen (only a few times to check exposure clipping) and using the electronic shutter 90% of the time. There is no need to take any spare batteries for a day’s shooting! I’m now saving up to buy this camera!

    1. I totally agree… the E-M1X is an amazing camera! IF folks could get over their obsession with full frame they would discover how powerful and versatile the E-M1X is an a photographic and video tool.

  2. Tom,

    I know this is a battery testing post but boy, I can’ t help but admire the swallow and red winged blackbird shots. 1 battery = over 2000 bird shots so that’s pro-grade battery life. Plus the quick-auto-focusing sans subject tracking is very impressive.

    By the way, the 2x teleconverter for the 40-150 f/2.8 and 300mm lenses was also announced by yesterday. Now, that would add a bit more reach to your arsenal, hopefully, with a tad less light penalty.

    1. Hi Oggie,

      I’ve been quite impressed with the battery life of the E-M1X so far… even when capturing single frames. Having 46% of battery #1 remaining after capturing 2,710 images is terrific.

      The 2X teleconverter is an interesting addition to the Olympus product line up. On the 40-150 mm f/2.8 it allow an efov of 600 mm @ f/5.6. Stopping the lens down to f/4 would make it a 600 mm f/8 equivalent. I think a lot of people would find this appealing rather than spending $3,300 CDN for the 300 mm f/4 prime. On a personal basis I would never buy a long telephoto prime lens. I would find it far too restricting. The Olympus 150-400 f/4.5 would be a much more appealing lens for my taste.

      We’ll have to see how my second client video test does next week. The initial one went pretty well.

      Tom
