Ask an iPhone user their biggest gripe about the Apple device and the overwhelming answer will be battery life—the amount of time the device runs before it needs to be recharged. The gadget’s notorious battery will reportedly be getting an upgrade in the new iPhone 7 and 7 Plus, which will be presented at a special event taking place on Sept. 7 at the Bill Graham Civic Auditorium in San Francisco, Calif.

Steve Hemmerstoffer (known on Twitter as @OnLeaks) took to the microblogging platform last month to reveal the higher battery capacity in new devices, citing an Apple source. According to The Telegraph, the iPhone 7 will feature a 1,960 mAh battery instead of the 1,715 mAh one available on the iPhone 6. The iPhone 7, on the other hand, will have a 2,910 mAh battery instead of the 2,750 mAh one on the iPhone 6 Plus.

 

 

Forbes reports that an increase in battery capacity is not trademark with each new generation of the device, as the iPhone 6S had 1715 mAh while the previous model, the iPhone 6, had 1810 mAH. However, it should be noted the decrease in capacity did not directly impact how long the device lasted since more efficient chipsets and operating systems compensated for the drop.

For the time being, users waiting for Apple’s official announcement on the next generation can preserve their battery life using Apple’s tips. The company recommends users update to the latest software, avoid extreme ambient temperatures and power down the device when not using the phone for long periods of time.

Other rumors surrounding the iPhone 7/7S launch is that the devices may be getting a dual-lens camera with the capacity to take SLR-quality photos and 3D images, the Home button and headphone jack may be gone, and Apple might finally be catching up to rival Samsung by making the gadget waterproof. Alleged leaks suggest the new device, which will reportedly be available in a blue color, will come with an entry level storage capacity of 32BG and will come with a 256GB option.
