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.

Samsung RAM... lol they make money from iphone also.... Kumar will cry now :)

You're talking like this is brand new information. Samsung has been providing parts for iPhones for years now.

His point wasn't about it being a brand new info, but to point out some Apple fans who bash Samsung's products.

Maybe samsungs own designed products, not Apple's designed components that Samsung was hired to build strictly based on Apple's specifications. I remember that when iPhone 5s came out with CPU that Apple hired Samsung to build - even Samsung was shocked it was a 64 bit.

@AlikMalix: You mean, please give us your DRAM that you developed? Samsung was surprised, says who? fanbos?

22. AlikMalix unregistered

Yep, because ram is what is what makes iPhone 5s and up 64bit. /s

Pretty much the only thing Apple designs is the SOC and the rest are components by other manufacturers.

Even this is a reference design... Apple has no idea

No matter what the OEM's specs, the other OEM still has to build it. Also Apple isn't using any special RAM. They buy the RAM Samsung already sells, just liek any other OEM.s I dont understand why you think Apple gets some special treatment. After all if what you claimed was true and Apple was special specing every single part, then the iPhone wouldn't cost $220 to make because making a special part for only one OEM would drive the cost up vs buying a part everyone will use. Apple's RAM is not special. Its the same RAM Samsung sells to everyone else. Gosh! Why do you feel the need to make up s**t? Apple has their CPU made to a special design because they design their own based off ARM's reference, just like everyone else. It is by far the only really unique component. Look at the part number for the Samsung RAM. I bet if you Googled it, you can find another phone using the same because RAM is a generic component. It is not special made for any OEM.

That is not true of every part that gets shoved into a phone. It just isn't. Apple buys components from Samsung just like any other OEM Some parts like the CPU are a specific Apple spec because it is their design. But Samsung does not build a specific RAM chip just for Apple. Here is a list of some DRAM numbers from Samsung - Get or find a part# for the RAM Apple is using and I bet its in this list. Which means other OEM's will be using it too. If your claim was 100% true, the iPhone wouldnt cost $220 to make. It would be at least twice as much. Your claim states that basically every part that goes into an iPhone is custom built to spec. That is false. It is not. Because custom built everything would be more expensive than using standard options. RAM has its own standard spec. Apple simply chooses the one that works best. Like if you bought RAM for your own PC. You would likely buy the fastest and lowest latency spec'd RAM. This is a fact for any product electronic or not. Your claim is just fanboy bulls**t. You know it and I know it even if no one else here is smart enough to know.

Hello... this isn't a new info for me that Apple use a Samsung component. I was just joking on one of the funny member here.

Gsmarena deserves guys like that. For removing disqus.

I'm sure the average iPhone user will be most displeased about the inclusion of Samsung RAM because they will think the phone might explode.

you have any idea how big samsung is? Samsung has 40 "different" companies under it and they bring in more money then apple or even google. They have their hands in everything and when i mean everything i mean everything! you already know about the phones and t.vs and fridges right? but what about their own hospital? or theme park or even military department???????? they build tanks and automatic weapon systems

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...!

@GreenMan : but I thought the A10's single core score was the best in the industry and the only thing that mattered. why are there so many cores now -- though it's nothing new that the iPhones had multi-cores for years? I thought fanbois were saying bigLittle architecture was terrible idea.

IOS is very efficient but it won't blow every Android out of the water by any means. When it comes to battery life Android wins hands down and it's not even close. Why? Because 4,5 and 6,000mah batteries are becoming commonplace in Android phones. IOS would probably win if it had batteries that large but they don't do they?

Not even, Android phones with the same battery capacity as iPhone 6/s plus have better battery life than the iPhone already with higher resolution screens. The iPhone 7 might be better but preliminary results agree it isn't by much if at all.

Well because an android with iPhone spec is considered mid range

"IOS would probably win if it had batteries that large but they don't do they?" - I hope with this same argument nobody would mention about screen tech(amoled) which iphone dont have.

I didn't mention it because it's amongst a long list of iPhone shortcomings and the iSheep would have a tantrum.

Standby for a phone that does nothing is somehow impressive? Yes Apple has a better standby mode. Because of these key facts. When a dev makes an app for IOS, everything must use Apple custom API's. Because of this limit, this also means apps can't exceed a certain barrier of performance. The down side to that is app on iOS even their Android equals do more. The plus side is no app on iOS will exceed a point, and when they try they basically crash or freeze. The downside to Android is, dev dont have a limite because they dont have RAM restrictions, because the apps have no direct access to RAM. All the app run in a sandbox. The benefit is simple. The dev can make the app have more features and never worry about RAM limits because in a sandbox there is no theoretical RAM limit. The Virtual Machine has direct access to RAM. If an app needs more RAM, the OS will simply increase its size in RAM to compensate for what the app needs. Like iOS, is the app asks for what exceeds the system, it will crash. But apps on Android have been proven to crash less. In FACT, all versions of Android combined, crash less apps than just one version of iOS. As far as bigLITTLE. We already have that and you're happy with 4 cores, we have as many has 8. 4 big 4 little. All efficient all clean. All work well. I am not syaing 8 cores are better than 4. What I am saying is 4 cores for each size, allows for more tasks to be handled vs just 2 cores each. For whatever task you need 2 cores for, I have 2 free cores to do other tasks. Yet even with all 4 tasks going, my device will use less power than just 2 or your cores. That can be seen in the battery-life. Also notice this. The iPhone surely has a powerful GPU vs the Mali and SnapDragon. But liek the SnapDragon, Apple's Power VR has the same drawback. Both are trying to have desktop prowness, but are less efficient. The mali is more efficient. Because of this, some games dont perform as good as they do on the other 2 options. But what you do get is better efficiency. Which means I can play the same game longer because my chip isnt ripping through the battery. Also since i can change the resolution on the Galaxy to match the iPhone, I can get near identical performance, without the battery burn. You are assuming the battery life will increase. I beg to differ. When a chipset uses more power, the way to stave off the number is to increase the battery size. So if now that the iPhone has a 200MaH larger cell, and it gets similar battery life as the previous model with a smaller battery, then that means the chip-set isn't running more efficient and that if you could change to the battery in the previous model, you would have less battery-life.
