The new iPhone 6s has a small battery: why?
The iPhone 6S has a 1715 mAh battery, while the iPhone 6 has a 1810 mAh battery. Relative to the same difference, judging by previous information leaks, there is an iPhone 6S Plus: it has a 2750 mAh battery, while the iPhone 6 Plus had a 2910 mAh battery.
What was the reason for such a slight, but still a decrease in battery capacity? So far, the main version is that reducing the physical size of the battery was needed in order to accommodate the Taptic Engine and Force Touch systems in the new iPhone for the new 3D display, which is now able to respond to different pressures.
If you believe the information on the Apple website, the decrease in battery did not affect the performance and operating time of the new smartphone: up to 14 and 24 hours of talk in third-generation networks, up to 10 and 16 days in standby mode, up to 10 and 12 hours of work on the Internet in mobile networks as well as up to 50 and 80 hours of audio playback on the iPhone 6s and 6s Plus, respectively.
How true these assurances will be known in the very near future, when new Apple products will be thoroughly tested by users and specialists already, but since the iPhone 6 was not the most capacious battery, such a decrease inspires some concern. It is hoped that Apple increased the performance of the new battery, and not only reduced its size and capacity.
