If you are iPhone user, you have always craved for better battery backup from your smartphone and Apple's new iPhone 7 might just give that to you.

The soon to be released iPhone 7 and larger-screen variant iPhone 7 Plus, which the Cupertino-based smartphone maker is expecting to be its knight in shinning armour as the company is on the backfoot with falling sales of iPhones, will come with slightly bumped up batteries at 1,735 mAh and 2,810 mAh respectively.

Photos directly from the factory floor posted on Chinese microblogging site Weibo revealed codes that shows the slight change in battery capacity.

But the real question will it be enough to sustain a longer duration of usage even if it is true? Not necessarily as a lot depends on the new A10 processor that will come with the new phone. The removal of the headphone jack will mean the Lightning port will also need to power any digital headphones without their own battery pack - a new source for iPhone battery drain.

However, the iPhone seems to be adding only incremental features to the 6S and can be termed as 'iPhone 6SS'. If that be the case then Apple can say goodbye to any chances of seeing its sales grow again though there is a lot of time till September for the smartphone-maker to add better features, specifications and make final amends. But it seems that the iPhone will see more innovation with the all glass iPhone 8.
