Your Samsung Galaxy S6 and Galaxy S6 edge questions answered: on design, software, cameras, battery life, and more
Hardware, performance, storage
Scorpion: How much free space will the 128 GB version have?
Firstly, we have to take into account that 128GB are equal to about 119.2GB when formatted. From this figure, we subtract the 15.26GB used by the operating system and the TouchWiz interface. What's left are about 104GB of free space.
Symon_Fleece: How fast is the new Touchwiz compared to the previous generations and to stock android?
Performance might vary from one device to another depending on how they're configured and what apps are running on them. In general, the new TouchWiz is smoother than older versions of the UI and probably on par with stock Android.
Camera and image quality
slavytodorov: Without having enabled it beforehand in the camera settings, can you take multiple photos by holding the shutter button (similar to the iPhone)?
Yes, holding down the camera shutter takes a burst. Both the on-screen button and the volume down button shoot bursts when held down.
Z3R091: Camera quality which one is better S6 or S6 Edge?
Both smartphones come with the same 16MP main and 5MP front cameras. They both take equally great photos.
Symon_Fleece: Can the S6 capture photos in RAW format, and can it control the shutter speed?
No and no. At this time, the stock camera does not give you the option to shoot RAW photos. You can't control the shutter speed manually. You may adjust the ISO, exposure compensation, metering mode, and focus, however.
Battery life and charging
JaneChenLong: Some said it work with Quick Charge 2.0 Could you CHECK IF IT'S work with ANY BRAND (not just samsung) Quick Charge 2.0 charger.
The Galaxy S6 and S6 edge charge rapidly from their stock chargers, but they're not certified Quick Charge 2.0 devices. The technology is available only on certain devices powered by a Qualcomm Snapdragon SoC. Still, if connected to a QuickCharge 2.0 charger, both smartphones will charge – not at the best rate the charger can provide, we suppose, but pretty fast nonetheless.
lessthanzero69: Can 10 mins of charge actually get you 4 hours of usage?
No, probably not. 10 minutes of charging will fill up about 15% of a Galaxy S5's battery, and if you plan on watching YouTube videos or playing games, its battery will die much sooner. But if, let's say, you keep your phone mostly on stand-by and use it to make the occasional phone call, then yes, getting 4 hours of usage after 10 minutes of charging seems plausible.
osanilevich: why do you suppose the edge has better battery life, when it technically has more screen real estate?
When testing the battery life of smartphones, we always set their displays at 200 nits of brighness. The Galaxy S6 edge, however, topped at 180 nits, which meant that its display was using less power. That's why it lasted more than the Galaxy S6, as we stated in our review. Its 2% larger battery may have also had a measurable effect.
shy2papa: How loud is the speaker and how is it compared to the iPhone 6 and HTC one m8 or m9
In terms of loudness, they're comparable. The Galaxy S6 and Galaxy S6 edge produce 73.7 and 75.4 decibels respectively, which is a tad higher than the One M9's 72.8 dB. The iPhone 6 stands between the two galaxies with its 74.5 dB. However, these are just benchmark figures measured with the phones reproducing white noise, not actual music. In other words, we test the loudness of the speakers, not their quality. If you need a phone with great-sounding speakers, the HTC One M8 or M9 would be a better pick.
goodnightjimbob: Does the s6 have a Wolfson DAC and what's the sound quality through headphones?
Yes. The audio codec inside the S6 and S6 edge is the WM1840. Unfortunately, the chip isn't listed on the Cirrus Logic web site so we don't have access to its datasheet or specs. It sounds great when paired with earphones that can be easily driven.
