Apple promo clip seemingly confirms smaller 1,715 mAh battery for iPhone 6s
Besides RAM counts, Apple has the annoying habit of keeping battery sizes a secret for as long as possible following an iPhone or iPad announcement. Sure, Cupertino always reveals estimated endurance numbers in various use cases off the bat, but that’s not quite the same thing.
Given the iPhone 6s and 6s Plus are almost identical to their predecessors from an architectural standpoint, just ever so slightly thicker, we weren’t surprised in the least to see them rated exactly the same as the 6 and 6 Plus in terms of autonomy.
Some even hoped the two new iPhones would grow their cell capacity, which doesn’t seem to be the case as far as the 4.7-inch model is concerned. Its internals are quickly flaunted in a marketing video focusing mostly on 3D Touch and the Taptic Engine, with the battery clearly shown at around the 2:50 mark inscribed as packing 1,715 mAh juice.
While you shouldn’t rule out this being an innocent mistake, perhaps caused by an early prototype starring in the clip, or components that didn’t ultimately make the cut, we’re fairly positive the figure will be corroborated by teardowns in the near future. Unless Apple drops the secrecy, and decides to confirm the tidbit, as well as whether the iPhone 6s and 6s Plus feature 1 or 2GB memory.
It also remains to be seen if the 6s shall fall behind its forerunner in battery life, or if the A9 chip can help it get to 14 continuous hours on 3G talk time, 10 hours of browsing, and 50 hours in audio playback. Remember, the iPhone 6’s ticker tips the scales at a marginally heftier 1,810 mAh, and both screens sport 1,334 x 750 pixels resolution.
