The iPhones have been among the world’s most popular smartphones. But their battery life has almost always disappointed users. A teardown of the iPhone 6S revealed that it featured only 1715mAh battery. Will the iPhone 7 sport a bigger battery? Probably not.

So, there is little chance of packing a bigger battery in a slimmer phone.

It’s also possible that A10 will be smaller than its predecessor, taking up less room inside the phone that can be used to increase the battery size.
Will iPhone 7 be the world’s first solar-powered smartphone?
Apple may also optimize its iOS platform to offer some battery gains. Earlier this year, Apple had patented a solar panel technology that is embedded in the screen. If the tech giant chooses to use the technology in iPhone 7, it will become the world’s first solar-powered smartphone. Since last year, Apple has also been hiring battery technology experts to enhance the battery life of its devices by better optimizing the hardware and software.
Earlier this week, Apple launched a smart battery case that offers up to 25 hours of extra talk time and 18 hours of web browsing. Even though Tim Cook defended it, the battery case has been widely criticized, and it is a weak solution to the battery life woes of iPhones.
