First Apple iPhone 7 teardown reveals 1960 mAh battery, 2 GB Samsung RAM


The retail iPhone 7 and 7 Plus units are already getting into the hands of users worldwide, and iFixit has apparently been queuing up in Australia again (where the iPhones launched first because of the time zone), since the chop shop already came out with an iPhone 7 Plus disassembly. 

The iFixit teardown revealed a 2900 mAh battery in the larger iPhone, contrary to yesterday's dismantling of an iPhone 7 Plus on video, which apparently was of a non-retail engineering version, as it showed a 2675 mAh battery pack, plus it had a tad different layout of the internal parts. That's all fine and dandy when it relates to the 7 Plus. Its battery is roughly similar to the one in its predecessor, but Apple promises an hour more battery life while browsing or watching vids due to hardware and software optimizations. What about the smaller iPhone 7, though?

Well, needless to say, it's first teardown wasn't far behind, and, while not by iFixit, it's pretty professionally done, revealing every nook and cranny inside the handset. We know what you'd like to know first - Apple said that the iPhone 7 will offer two more hours of battery life when watching media or browsing, compared to the iPhone 6s, which is a 20% bump in endurance.

Where does this jump come from? Well, from the new 7.45 Whr energy battery, which, at 3.8 voltage, returns no less than 1960 mAh capacity for the unit. The iPhone 6s comes with a 1715 mAh juicer, so the 20 % bump in battery life for the iPhone 7 can be directly attributed to the larger battery, plus the same hardware and software optimizations that are present in the iPhone 7 Plus.

To sum it up, Apple decided to use the space freed up by the removal of the audio jack to prolong the battery life of the smaller iPhone, which was a bit of a weak point before, but for equipping the larger iPhone with a dual camera set that brings optical zoom, since the 5.5-incher already had a pretty respectable endurance. Decisions, decisions.

As for the rest of the things we learn from the first iPhone 7 teardown, there weren't many mysteries left, besides the pressing question why Apple says "stereo speakers" for the bottom sound blaster, but "stereo speaker" for the top one that doubles as an earpiece.

Well, we'll spare you the suspense, it seems that there is only a single speaker at the bottom, but there are apparently two mics there, along with a third one at the top. The 2 GB RAM module is of Samsung make, while the 128 GB flash memory chip is sourced by Hynix.
