Our summer battery and display test: the beach effect

14 July 2024
We torture-tested a selection of phones to see how bright sunlight affects their battery life.

Put flagship phones to record 4k video outdoors.
Let's see if besides xperia, any else can pass 15 min.
Xperia can do hours of 4k30 or 60.

    You guys could've easily just did 2 different tests, first do the display test to see how the display reacts by recording 4k60 videos for 30 mins and then checking the brightness. That would be hellish for the displays if you really wanted a stress test. If not you could've only done it for 2-5 mins as most people like to take some stories and stuff.

    For the battery you could've come another day or used a power bank to charge them all back to 100% and then do the test.

    Also, what's the point of a 100% white window? Nobody watches anything in the sun with that. Should've used your regular 75% white window test and better yet, just checked the brightness of the website at some place in the display. More realistic.

    Best test scenario would be to scroll instagram as it's quite heavy for a social media app and see the brightness in a similar post in those phones to simulate looking at a normal shot. Due to the smaller size of the photos, the fully white window would be smaller like 30-60% size and so would be more realistic and allow you to see how the phones fare in a real scenario.

    Idk who browses web pages for hours on the beach, that's just cringe lmao, most people go on TikTok, Youtube or Insta nowadays and old people go on Facebook. Web browsing is mostly done at home.

      IpsDisplay, 14 Jul 2024"You'll have to trust us on this, because it'... moreit;s impossible to capture because it is. It's tough to show on camera how legible a phone's display is. Your eyes adjust, cameras do not. They choose a specific exposure and ISO and have an SDR photo out at the end. If it were HDR maybe it could've been somewhat replicated but historically displays were never kind to cameras so yeah it's tough. There's a reason why cameras aren't used and lux meters and stuff are used.

      DXOmark just gives an approximation that you can use to get an idea of how the displays fare but they can never be used as a substitute for your eyes. If they don't say that then their reliability is questionable. The legendary Vincent Teoh from HDTV Test always has a disclaimer for this type of thing and RTINGS as well says that these are subjectively done. Only objective thing is the brightness and the colorimetry info that doesn't help much unless you really know your stuff.

        Could you guys do such a test between the samsung s24 ultra and the iphone 15 pro max ??

          "You'll have to trust us on this, because it's essentially impossible to capture in a photo or on video, but all phones remained easily legible throughout the test"

          Correct me if I'm wrong but doesn't DXOMARK do display test and capture the results under some high LUX environments

          Makes me think maybe it's not impossible, but maybe gsmarena doesn't have the technical resources or knowledge how to get it done

          Which if true would make sense because gsmarena's review technicality has been stagnant for years especially display reviews which is basically just peak brightness, low brightness and colour accuracy

            Inventor class is different to copy paste class

              I love these new type of test. I hope you guys make a series out of it. maybe named it something like Real-World Usage Assessment or something, idk.

                What's up with that big of drop with s24 ultra? It gets dimmer than ips panels on laptops

                  Oh wow, new segment. I like

                    i wonder how warm did the rog phone got after recording all these phones in the sun
