iPhone 8 and iPhone 8 Plus come with smaller batteries, sizes revealed


The Apple iPhone 8 and iPhone 8 Plus come with smaller sized batteries than earlier generation iPhones, and the iPhone 8 Plus in particular comes with the smallest battery ever used in a Plus-sized iPhone. The information comes from a listing of the new iPhones with Chinese regulator TENAA.

Interestingly, Apple says officially that the iPhone 8 and 8 Plus will last as long as previous iPhones and this is likely due to the more efficient Apple A11 Bionic chip.


Here are the newly-revealed iPhone 8 and iPhone 8 Plus battery sizes:



So... what is the reason for those smaller battery sizes? Is it an attempt to make a thinner phone? Is it the new glass back and wireless charging that take up more space? We can only guess, but the reduced battery sizes are a fact.

Another curious detail that the listing confirms is the amount of RAM in the two new iPhones: 2GB of RAM in the iPhone 8 and 3GB of RAM in the iPhone 8 Plus.

This is far from the amount of RAM you get with most high-end Android phones that ship with 4GB or 6GB of the stuff, but keep in mind that Apple's iOS is a different architecture that is a little bit better in handling those resources.

but why smaller batteries??? I want a phone to last as much as possible not as much the OEM thinks it's reasonably to last... i bet they did this to reduce the weight... such a shame...

"what is the reason for those smaller battery sizes?" Because it's cheaper.. Cheaper component = Bigger profit

0.1$ maybe... Multiply that by 50Million units sold, and they get extra $5million, that's enough to cover all media review expenses..

They actually weight more than their predecessors so....

Most probably the reason is wireless charging. Check that teardown of Samsung S8. https://youtu.be/GRmY-4HKVIk?t=1m47s It has a flat layer of copper coil inside of a plastic envelope for wireless charging receiver, lies between the battery and glass back plate. It's thin, but still eats up precious volume. That's like making a phone thinner.

That may be a reason, but that still doesn't make sense. Take a look at other flagships that comes with wireless charging. Apple fans will probably defend their father but it won't take away the fact that bigger battery means better battery life.

Compare to 7 Plus, I believe that's the main reason of smaller battery. S8+ has much bigger battery, but its body is thicker and it has flexible OLED screen. OLEDs are thinner than LCDs and flexible OLEDs are thinner than rigid ones. Of course there are many other factors and I'm not defending Apple here.

Haha... Sorry If I sounded like I was bashing you. I was not. This trend for thinner waistline should stop, no really. Imagine the capacity of battery that could fit in a phone with a thickness of 9mm if one could almost fit 3K+ mAh in a phone with 7mm.

I'm an iPhone-sided person for the most part that matters to me, but I won't defend Apple. This is surely a bad move and I want Apple to go Samsung's way by making the next iPhones thicker and including a higher-capacity battery. You can be sure many others will want the same too. Apple could keep the thickness just under 9mm, and it should reduce the camera bump too. Thereby making its customers happy!

Don't forget they removed the finger print scanner in the iPhone X model and still they are going to buy it.

The bais for Apple is going to be great his year. Small batteries, wack design and software full of gimmicks and fun tricks for teenagers. Watch how the media will find away to forgive them. A11 is the only impressive thing on the iPhones but speed ain’t everything. The X got just a new OLED screen and phonearena is going to give it a 10. Lol

The display has ~458 ppi density while competitors are from 520 ppi up.. Still, as you said, for PA will be the best display.. just because Apple gives good money for nice "articles".

Small battery but improved battery life, how?, optimization and new CPU architecture. Same design is better than ugly looking tall Note 8. People are not tired of it, they love it. No headphone jack is the future and people already look past that thing anyway. But didn't you see all the improvements like great CPU, GPU, New Cameras, True tone display, better front camera, wireless charging etc..? oh wait, you are one of those stupid retarded Samsung fanboys...lol

Dude, don't try so hard. We need to accept that Apple is trying to rip people off, even with the iPhone X....

Its true , that processors are getting efficient every year . But it makes no sense. All the manufacturers are going backwards when it come to batterysize for sure . Ok . They dont want to increase it, but at least dont make it smaller. This is getting ridiculous. I mean it has been a common scenario for all the flagships this year . Very frustrating....

Not all. Look at LG compared to the past year.

Why in the world do 1xxxmAh batteries still exist in a flagship phone?
