IMPORTANT: in real life, the differences won't be this pronounced. It's Playing: 42% and 44% (tested twice, on both the previous (3.8.1) and the just-released (3.9) version)ĪVPlayer: 13% (useless image, though - so far, all(!) standard H.264-converted, originally Hi10P anime vids with SSA subs have turned out to be hardware-unplayable by AVPlayer) The battery drain figures of the most current versions of the most important video players (also) capable of playing back MKV videos (with AppStore apps, semi-)hardware accelerated are as follows: I made absolutely sure I started playback at 100% charge level. All this in flight mode and after a reset before every playback, making sure nothing else ran. The tests have all been done in exactly the same circumstances: on an iOS 6.1.2 iPhone 5 set to minimal brightness and auto brightness off (so that the screen's power usage is as low as possible to make it possible to better measure the power usage of the players themselves), keeping the iPhone in exactly the same position during the tests (no orientation changes occurred during playback). ![]() (The longer, the better, as it emphasizes the differences between the players.) For the test, I used the standard H.264 (non-Hi10P) conversion (using the Normal preset, default settings (Q=20, resulting in a file sized 1,504,815,241 bytes) with audio and subtitle pass-thru in Handbrake) of a Hi10P video. To get as reliable results as possible, I've used a two-hour-long movie for testing. (This is what I referred to my initial answer.) The results I got have shown I was wrong: utilizing hardware accelerated playback directly on a jailbroken device, actually, resulted in some 50% more battery drain in my tests. This is why it's so popular among video freaks.)Īt first, I had thought AppStore-based players would definitely have a handicap playing back MKV files in semi-hardware-accelerated mode because they would need to quickly cut and remux the MKV files in the background. When you rip your own Blu-ray discs with the excellent MakeMKV, MKV is the container the app exports your disc to. (MKV containers offer in many cases by far the most flexible video storage capabilities for example, when trying to store animated subtitles very widely used in karaoke and anime. One of my readers (question HERE my initial answer HERE) asked me to elaborate on the power usage of the recommended MKV players.
