The Le Max 2 handles daily duties very well thanks to its snappy CPU and loads of RAM. We noticed a bit of heating during gaming and when recording 4K video but nothing too alarming. On average you have about 3.5GB of free RAM at your disposal so it's very rare that you'll encounter any major lag during usage. The interface runs smooth although it does lack the lightning fast responsiveness that Nexus devices offer. The earpiece is decently loud for taking calls when commuting, and the phone had no trouble with our 4G networks here. In terms of benchmarks, the Le Max 2 delivered 136, 505 points in AnTuTu and 53fps in GFXbench, both of which are very good scores.The video player handles 4K videos with ease and also gives you options for a pop-out window; casting it to a compatible receiver; toggling between captions, and even trimming files. LeEco has also added all the necessary video and audio codecs to support popular formats. The phone supports Dolby Atmos, which helps boost the overall soundstage. This effect is best experienced with earphones rather than on the mono speaker. The volume level for headphones is pretty good and we found that keeping the level at the halfway mark was sufficient most of the time. Audio quality is good even with the 3.5mm adapter; however higher impedance headphones don't always sound their best through it. The CDLA earphones offer better audio separation and crisper highs but due the design of the earbuds, this pair lacks good bass.
