Iphone 6s Battery Life Hours. 11 hours 50 hours. In Basemark OS II we start off with a pretty shocking result as the iPhone 6s lasts less than three hours in this test but looking at the battery score its pretty clear that the reason why.
About 7 to 14 hours for both phones. The iPhone 6s also offers up to 11 hours of HD video playback and up to to 50 hours of audio playback. Enter the iPhone 6s and its first battery life tests - it managed to nail an excellent score during our own surviving more than 8 hours of screen-on time while displaying our proprietary imagery mashup that aims to emulate real-world usage.
Ive only had my iPhone 6s since February was hoping to hold out and keep my 5s until the 7 came out but I got impatient but for the past couple weeks the battery life has been draining extremely fast.
Built-in rechargeable lithium-ion battery. It also offers up to 12 hours of Wi-Fi use on 3G LTE and Wi-Fi up to 14 hours of HD video playback and up to 80 hours of audio playback. Watching online videos and using GPS drains the battery pretty quick with screen brightness being also a factor in the battery consumption. In terms of web browsing while using the latest version of Safari the battery of the iPhone 6S lasted for 12 hours and 27 minutes.
