14 DAY TRIAL // New smartphones, especially flagships, typically launch with bigger batteries, as they usually get new features that require more power to work correctly and offer an autonomy of at least one day.
This was also Apple’s purpose with the iPhone 7 and the iPhone 7 Plus, as the company aimed to build a device that can last at least for one day with moderate usage. And since the Plus is getting several important upgrades, including a dual-camera system and 3 GB of RAM, it obviously needs more battery juice to perform all tasks and a bigger battery pretty much made sense.
But not if you’re asking Apple, though, as Cupertino has somehow considered that reducing battery capacity is actually a good idea. Because according to a recent video showing a teardown of the iPhone 7 Plus, the device ships with a battery of just 2,675 mAh, smaller than the 2,750 unit on the 6s Plus.
Here’s the context: the video you see here, and which we cannot guarantee is 100 percent real - although it certainly looks so - shows a teardown of the new, bigger iPhone. As PhoneArena sharply noticed, the battery pack, which can be clearly seen in the video, has an electrical energy of 10.22 Wh and 3.82 voltage.
Battery smaller than on the 6s Plus
To calculate the actual capacity of the battery, all we have to do is turn to the following formula using the aforementioned values:
"How’s this possible?" you might ask. The only way to make this happen is with hardcore software optimizations, so unless Apple was really aggressive with optimizations in iOS 10, it might be impossible to get the iPhone 7 Plus last for one full day.
Certainly, there’s more to find out and we’ll eventually hear everything about the battery used on both iPhones on Friday when sales officially kick off. For the moment, however, things aren’t looking that great for the Cupertino giant especially because its number one rival, the Samsung Galaxy Note 7, has a 3,500 mAh battery.
UPDATE: An iFixIt teardown shows that the iPhone 7 Plus is in fact equipped with a 2,900 mAh battery and it makes sense given the upgraded hardware.
