iPhone XS, XS Max and XR battery capacity size revealed

iPhone XS, XS Max and XR battery capacity size revealed
The three newest iPhones – the XS, XS Max and XR – have now all passed certification in China and a mandatory part of that is disclosure of the actual battery capacity of the devices, a number that Apple does not share on its own website.

So for all who are curious, here are the battery capacity sizes on all three new iPhones:

The iPhone XS Max in particular has the largest battery ever put on an iPhone, but interestingly, it is the iPhone XR that Apple says will last longest of the three, outlasting last year's iPhone battery champ, the 8 Plus, by a full hour and a half. Another curious tidbit is that the new iPhone XS actually seems to have a slightly smaller battery (2,658mAh vs 2,716mAh) than last year's iPhone X.

Of course, keep in mind that battery size alone is not what makes for great actual battery life. Software optimizations and effective power management of the internal components of a phone, as well as the screen resolution and brightness, have key roles as well.

We will be testing the battery life of all new iPhones soon, so stay tuned.

They don't have test models.

Why doesn't Apple see that we don't need thin phones, when te battery is insuficient… I (and many others) would prefer a Phone that goes through a full day of heavy usage, without worrying about the battery all the time. Even when the Phone would be 0.5 times thicker. That's actually why I still got my LG V20 with removable battery.

There was a race to make the thinnest phone/tablet before there was a race to eliminate bezels.

Why bother? people will still line up in front of their store anyway.. And smaller battery is cheaper, that's also mean "more profit".

This is hardly unexpected, in fact it's pretty normal for Apple.

Wow that’s amazing. They said the XS Max has the biggest battery ever put into an iPhone, but if this is true then the iPhone XR actually has the biggest battery ever put into an iPhone too. Like iPhone 6 Plus got like 11.1Wh which is about 2915 mAh ? The XR phone actually surprise with this. It also explains how it could last so long. An super efficient LCD instead of larger OLED and a battery that is just a bit smaller equals better battery life. This probably has to do with much more bigger massive wireless charging coil. Despite XS fusing two high capacity lithium polymer cells into one which dramatically increases capacity, this was used ap to make the coils bigger. That translates to much faster wireless charging without any increase in power. Efficiency is the key ! Maybe even higher wattage will come trough with an software update like a year ago. Who knows. And of course 7nm A12 bionic sips power by drops. So display is the biggest problem in here and big screen takes up a lot of power.

XR has 720p screen... That is why it will last more

Plus the screen is also smaller so it has less pixels to push

My iPhone X has average battery life. I think Apple deliberately put mediocre battery so they can put this as a feature in the future.

As long as my iphone last a day, I’m good. But hoping  cam get distant wireless charging. Excited to get my iphone Max 512gb gold.

From 2,716mAh to 2,658mAh? Really, apple? 100% sure this will revive the wall-hugging jokes.

I realize that optimization plays a key role in the iPhones concerning battery life, but it wouldn’t kill Apple to put much larger batteries in their iPhones. Imaging the battery life if they had put a 4,000mAh battery in the XS Max, 3,500mAh battery in the XS, and a 3,200mAh battery in the XR? iPhones have amazing standby time, and the 8 Plus really did have good battery life, but once you get into heavy usage territory, the battery begins to drop at a pretty steady pace.

the only one that optimizes the iPhone is PA. Apple should give them work

True. But you also have to consider hardware. More powerful hardware, like more ram, faster modems, bigger displays, more powerful chips and the like, then a bigger battery is needed to power them. OS optimizing just controls how much a phone can do in a clock cycle as the battery depletes. When you consider the iPhone has the least feature vs other devices in its price range, the fact you get only 6 hours is lame. If I only got 6 hours of my Note 9, I could understand considering it is a powerhouse device compared to the iPhone. The iPhone is not optimized all that well since it dies in 5 hours on most real world tests and other phones last nearly 2 hours longer that hve more features and capabilities

Save your “I hate Apple, therefore I must bash them as I worship Samsung” propaganda for someone else, techie. I own an 8 Plus, and the battery has never died in 5 hours, and I’m a heavy user of smartphones. When you design/make the hardware and the OS entirely, you can optimize the hardware and the software to provide excellent power management.

My phone is smaller and thinner with almost 3000mAh. Ridiculous batteries

Is it the iPhone 6 Plus ?

Could at least put 3500mah in the max.

Weird numbers as always, and small capacity as always.

Wow Apple! a friggin' 3000+ mah battery on a 6.5 inch phone. better this thing lasts for long, especially if someone is paying 1000+ $.

It'll probably have great standby time. But once you start using it the battery will be average at best. My 8plus doesn't even last the whole day if i use it too much.

How do you have such a small battery in a 6" device? Yet the Note 8 was blasted for a 3300mah battery in a device of similar size. Considering the fact the PCB in the iPhone is dual layered and smaller. There is no added new inter al hardwate. Yet the Note 9 has far more inside and has a 4000MaH battery. If Apple wants to keep raising prices, then we need value for the cost. If other outfits can make a phone for $1000 with more, then Apple can do. As much money as they have, they need to stop skimping on hardware festures especially.

I just dont understand how the past plus models of iPhones had such small bats, for their size and yt other OEMs have largee batteries in smaller phones. Schiller made such a big deal of claiming getting an extra hour of ussge. They keep going up on price. I mean it took 5 years just to get an IP68 rated device, even without a Jack and no button. A 3100mah battery in. 6.5" device? Yet the Noteb9 is 6.4 which is marginally smaller, yet houses 4000. Even 3500 mah would have been better.
