FrancThe Ouaz website Nowhereelse.fr, which has been very active lately regarding leaks regarding the upcoming iPhone 6s and iPhone 6s Plus, posted a photo of the battery for iPhone 6s, which is labeled exactly the same as from Apple suppliers, which suggests that it should be genuine. The bad news is that the battery in question has a capacity of 1715 mAh, which is less than the current 1810 mAh battery in iPhone 6. However, the server mentioned that it could also be a battery for iPhone 6c, whose production was suspended in the spring of this year.
The reason why the battery in iPhone The 6s could have had a smaller capacity is quite clear – Force Touch technology also brings with it the disadvantage of requiring an additional computer.onenty and therefore either the body of the phone must be enlarged or some components must be reducedonenty such as batteries. But as was revealed yesterday, iPhone The 6s will likely have a 0,2mm thicker body and, according to this information, probably a smaller battery capacity so that the Force Touch display can be used.
Another speculation is that the battery could be intended for iPhone 6c, which should offer a 4″ display, approximately the same size as iPhone 5s. The battery was even manufactured in March 2015, when according to speculation, production of the smaller model was supposed to be suspended. But on the other hand, the 4″ iPhone The 6s offered a relatively large capacity compared to iPhone 5s (1558mAh) and iPhone 5c (1510 mAh) and the terminal for connecting the battery is identical to the one used for the battery for iPhone 6, so there is a possibility that the smaller battery is really intended for iPhone 6s.
