Apple during the presentation of the iPhone 6s and iPhone 6s Plus silent about capacity batteries smartphones and only showed a promotional video, which flashed a shot of the battery. As it turns out, the capacity of the used power source is decreased compared to the iPhone 6 and iPhone 6s Plus.
The iPhone 6 is set to the battery of 1810 mAh. In the iPhone 6s, judging by the video, applied battery capacity 1715 mAh. That is, the reduced capacity of 95 mAh, or approximately 5%. iPhone 6s Plus, if we are to believe the revelations of the Taiwanese media, got the battery 2750 mAh, 165 mAh less than the iPhone 6.
Thus, according to the specifications on the Apple website, the iPhone 6s and iPhone 6 offer the same battery life: up to 14 hours talk time on 3G, up to 10 hours of Internet through 3G/4G, up to 11 hours of HD video playback or up to 50 hours of music. The iPhone 6 Plus and iPhone 6s Plus the indicators are also the same: up to 24 hours of talktime on 3G, up to 12 hours web surfing on 3G/LTE/Wi‑Fi, up to 14 hours of HD video playback, up to 80 hours of music playback and up to 16 days of operation in standby mode.
Obviously, to maintain the indicators of autonomy when using the smaller battery capacity managed through the use of more modern components, in particular of Apple’s A9 processor with motion coprocessor M9 instead of the Apple A8 chip with M8 coprocessor. As far as actual performance time battery life will vary, will show the practical tests.
