Apple iPhone 7 Plus teardown reveals 2,900mAh battery, 3GB of RAM and more


You can buy the Apple iPhone 7 and iPhone 7 Plus starting today, but if you're the kind of person who wants to know all the little details before he spends a fortune on a new gadget, you might also want to take a look at what's inside the phone.

And there's a lot to explore, as the device surgeons from iFixit have taken the larger iPhone 7 Plus for their complete teardown treatment revealing all the interesting parts that blend together to make the phone what it is.

The iPhone 7 Plus teardown also reveals some of Apple's secret sauce: what's the size of the battery? How much RAM is there? Those are things that Apple does not speak about, but that are still important to many users.

Let's answer them right away: the battery inside the larger new iPhone is a 3.82V and 11.1Wh cell, or in more common terms, it's a 2900 mAh unit, slightly larger than the 2,750mAh battery on the iPhone 6s Plus, yet still smaller than the 2,915mAh cell on the iPhone 6 Plus (which had a headphone jack, but did not have the Taptic engine, in case you're wondering).

The second revelation about the iPhone 7 Plus from iFixit's teardown concerns the RAM: it's now confirmed that there's 3GB of LPDDR4 RAM on the larger iPhone. Some have speculated that the extra RAM is used by the camera that smartly blends images from the two rear-facing cameras for a better composed image that is made every time you take a picture, but this is just an educated guess that's floating around.

The rest is dismantled parts, repair instructions and other interesting tid-bits that you can see in the images and at the source link right below.

Finally, a first comment...! GreenMan is pleased...!!! Thanks for the heads-up, PA... Anyhow, the battery MIGHT be slightly smaller by 15mAh... But its the SOFTWARE that matters the most... And we all know (although some don't like to admit) how efficient iOS is... And its standby is simply outstanding... And now that A10 has a Quad Core with bigLITTLE architecture... The battery life will increase EVEN MORE! Slower yet efficient cores humming during simple tasks, and powerful cores reserved for extensive tasks... I'm sure the battery life of iPhone 7 will simply blow anything (Read: Android) out of the water! Maybe even Windows Phone, Who knows? iDay7...!

Hardware matters much more. iPhone 6s proves that fact, but anyhow you missed it. It manages better battery life with a 14/16nm FinFET SoC, DESPITE smaller battery. Now they claims better battery life again with HARDWARE. Standby energy consumption is least relevant at battery life even if you are a light user.

Iphone 7 battery will not blow Android phones.. The article is about iPhone 7 Plus. Did you bother to read before you post a comment?

Ah Apple still has the Cirrus Logic chipset inside...I think audio quality shouldn't be THAT bad

I'm sure it won't beat the Mate 8 battery life

I would pay upwards of $1000 for a 'IFrankenphone mod'. By that, I mean the battery made user replaceable. Quire surprised nobody (of course including iFixit and / or Anker) has made a successful attempt after almost a decade of iPhones at their disection.

I thought 1GB would be enogh for the smooth little IOS.. hahahaha

Uh, they really don't, that's why they are not going over board with 6 and 8GB ram.

as the os progresses with more features more ram is needed to process it. early ios didnt need more ram as it was sufficient.

Why Apple doesn't reveal this information in their keynote? Why do we have to wait for someone to tear down the device to get such information?

Plastic something, did you care how much RAM Nokia 3310 had...? What kind of processor out had...? Or perhaps, did you care about Nokia 1100...? N70...? E71...? Blackberry Quark...? You didn't care because they didn't lag...! Why I got into computer hardware customization a one and a half decade ago...? I got into it when my computer started to LAG...! I looked up the remedy in books... And only then I understand what RAM and Processor are and what they do...! iDay7!

GreenMan You're perspective about hardware specs is subjective. Quote: "You didn't care because they didn't lag...!" Really? If no one cared about the amount of RAM and battery capacity in the iPhone, then why did Apple bump up the hardware specs of the iPhone 7 Plus? Not everyone buys devices ignorantly; people have the right to know what they're paying for. By your logic, you won't care if, in 2016, Apple sells you the iPhone5 for $700, because the iPhone5 "does not lag", despite it's outdated specs... Right? Such comments like that makes you guilty of the very same "blind praise" you accuse people of.

because it's a shame... it's below competitor's specs

Because the customers that buy iPhones aren't in love with the spec sheet, they're in love with the device's performance, image quality, screen quality, design, and battery life. They are sold on benefits, not specs. This is a concept that a lot of Android users refuse to understand.

I admit I am like this, I dont care if the base OS is lagging because I feel like I have the power to change everything inside the device :D I dont care if the default camera has bad post processing software, because I know there are plenty of "ported OEM" camera I can try. I dont care if the IPS screen has a light yellow or blue tint because I can set it on kernel level screen setting :D I am the owner of the device.

... WELL, SPECS DOESN'T MATTER TO APPLE /iOS, YET THE CAMERA, THE RAM, THE ROM, THE SCREEN SIZE AND RESOLUTION, AND EVEN THE BATTERY KEEPS INCREASING. WE WILL NOT COMPLAIN NOW...

Apple is adding specs as needed, not because that's what customers want. The end user experience is what matters to Apple.

While I'm not a fan of Apple, I agree with this statement. I understand it has its own audience that isn't about status or style, but about a phone that simply works. The 7 plus looks like a good phone. I like the matte black more than the jet black. Good job Apple.

The article forgets to mention that the second (new) grill at the bottom which pretends to be a speaker grill, is actually a dummy/fake as seen in the teardown. There's nothing behind it, also because the second speaker actually sits at the top of the phone, where the phone call speaker sits too. Rather odd to add such a non functional faux design feature for no other reason than symmetry.

Whilst I agree it's pointless, the teardown indicates a plastic part in there used to channel sound...

That's very poor for an flagship!

Depends how it performs really doesn't it?

Both how it performs and what it's useful for...

I am glad apple bumped up specs, RAM is essential and although 2 cores are enough bigLITTLE improves battery life. I hope they improve design and screen (reduce bezels and thickness to bigger model) next year.

It's not big little, apple uses it's own in house controller/task manager to switch between the cores as needed

31. Ruturaj

2 high performing cores and 2 power efficient cores is bigLITTLEish.

iPhone 7 Plus is a very nice phone, just a shame it's little bulky, runs iOS and costs £700+. Note 7 has a smaller profile which is odd considered the display is smaller on the iPhone, definitely an area Apple need to do more work.
