The dark satanic rumour mill claims that Apple’s will launch the 2019 iPhone generation in September with a series of massive upgrades, including in the battery department.

Top-rated Apple analyst Ming-Chi Kuo says in a note to investors that the Cupertino-based tech giant would use larger batteries on all three models debuting this year.

Apple is expected to stick with the current three-model lineup that includes 5.8-inch, 6.1-inch, and 6.5-inch models,  while the design is likely to remain largely the same.

Ming-Chi said the iPhone XS would come with a battery whose capacity would be increased by up to 25 percent. The iPhone XS Max itself will get a massive upgrade of around 15 percent, while the iPhone XR, which runs on a 2,942 mAh battery, would receive a stonking increase of just five percent.

The reason for these massive upgrades, at least on the iPhone XS and the XS Max, is that Apple wants to add bilateral wireless charging.

These have been available on Android for a while now, and it seems that Apple thinks that it is safe enough to claim to have invented it. Bilateral wireless charging allows a smartphone to charge other devices using their batteries wirelessly. On the iPhone, Apple most likely wants to provide users with the added convenience of charging the Apple Watch or the AirPods on the go whenever a standard charger can’t be used.

By increasing the battery capacity, Apple tries to make sure that charging other devices wouldn’t substantially impact the experience with the iPhone.

Of course, this whole thing could be abandoned if Apple can’t get it to go.
