Thank you for backing up your claims.
I was trying to understand where the assumption that the extra ram is for the camera system came from and what the technical reason is to have more ram when adding that second lens. Because previously phones had two cameras too, just not pointing in the same direction.
The extra 1GB of ram does make a difference. Your original intuition was indeed correct.
That extra 1GB of ram is not excommunicated from the device and solely active when using the second camera lens lol...how on earth that became "common knowledge" is beyond me. It should be considered common "erroneous" knowledge. It is true that the 1GB of ram is there for image processing, but are you taking photos 24/7 with a telephoto lens?
No, you are not. That 1GB of ram does not magically become deactivated unless you use the camera. It is still there for general tasks and functions. So yes, the extra 1GB of ram in the 7+, 8+, X, XR, XS/Max does make a difference. For iOS right now, it is not a noticeable difference. Maybe it will be in the future, but right now no one is multitasking with that many apps on their mobile devices. Usually 3-4 max is what people use in normal work flow. iOS also manages apps differently
I don't have a Plus model iPhone anymore, but i do have a X and XR and I can tell you from loading apps and switching them, the RAM management is identical - despite one having a single lens, and the other having dual lenses. They refresh apps the same.
The extra ram certainly helps with image processing, and is probably the reason Apple has an extra GB sure, but it doesn't magically disappear.
Here's a simple video showing the X vs the 8; same processors and same type of ram but different quantity. I have received near-identical results between an iPhone 7 and iPhone X.
There was a basic test done by 9to5 mac that showed safari tabs, and it only looked at one singular aspect (safari tabs) whereas this shows the general management
Anyways....Clearly, the extra GB of ram still functions as an extra GB of ram when the phone is not processing images.
These videos are hopefully more indicative of proof than selectively chosen clippings from news outings who report things as fact and confuse the people who read them, as these are the authors who probably don't know what the difference is between a byte and a bit
I’ll put it like this... the battery in the Xʀ is what makes me continue to use this phone. It’s truly mind blowing how much better it is than that of the Max.
Coming from an owner of a X, XS Max and the Xʀ I can assure you the display is great. I used the X from November of 2017 until September of 2018. After that I bought the Max and used it until October when the Xʀ came out. I personally have not switched phones since October 26th. I’ve had no desire to use my Max or X.
Then one thing people will try and talk about is the RAM. It is 3GB vs 4GB. However the extra GB of RAM in the XS and Max is only for help running the telephoto lens. The Xʀ doesn’t need the extra GB for that reason.
This is incorrect. Even if the extra GB of ram is required for image processing with dual lenses, it does not magically shut off when you are not processing an image.
The RAM is soldered right on the SoC. It is there for every function of the phone.
I know what you are talking about re: "it is everywhere on the internet since the iPhone 7 Plus days"....none
of these sites that reported it back in 2016 seemed to grasp that. Probably because they don't know what a SoC is lol. It was a classic case of "monkey see, monkey do" reporting, Apple said this is what the extra GB of ram is used for, and people took it and ran with it. Sure that is why they added the extra GB, but it doesn't mean it turns off and stops working. Yet, many people fell for it and now pass it off as fact.
The thing is, it doesn't matter because iOS 12 will perform 99.9% identically on 2GB iPhones as it will on 4GB iPhones. iOS on iPhones first of all does not have true multitasking function, and second of all no one needs 10 apps running in the background. If you do need that, you're using the wrong device for your work flow.
