Different types of monitor technologies have different levels of efficiency, you cannot judge a monitors power consumption based purely on pixel count. a 1080p TV will draw drastically more power than a 2160p screen the size of a phone. as for power usage of a GPU, drawing 2D UI's should not amount to a significant workload and battery life should not be affected much. it would probably the phone's least concern as far as battery goes.
as for more demanding rendering. if you take 3 equal GPU's, make them render a 3D scene, one renders at say 720p and the second 1440p, and the third 2160p. then the more demanding ones may draw more power than the other of one of them hits a framerate cap. if the 720p rendering GPU is able to render at say 90fps but the framerate cap is 60, it's going to roughly work at 2 thirds of its full capacity because the gpu knows that working at full effect, a 3rd of its frames wouldnt be able to be displayed by the monitor and would have to be dropped due to deltatime. thus the gpu rendering at 720p would not draw its maximum tdp
however, lets say the GPU's rendering at 1440p and 2160p are falling short of the 60fps target at 45 fps and 25fps respectively. these 2 GPU's would draw the same amount of power because none of them are hitting the framerate cap and thus are running at full power trying their best to reach the cap. so in conclusion GPU 1 would not be drawing its maximum tdp because it hits its 60fps target with power to spare, GPU 1 and 2 rendering at 1440p and 2160p respectively are running at full power trying to reach the cap. so resolution in rendering can affect power consumption, but only if increasing the resolution results in the gpu falling short of its framerate target
you would be CPU bound in this scenario, unless you had a really really crappy GPU. as i said, 2D UI's are generally not demanding. one notable exception is the iOS 7 and up homescreen due to the Gaussian blur. in the right conditions, it can even make the iPad pro drop frames, notably when returning to the homescreen from the recent apps screen. i suspect the reason the iPad pro does this and not for example iPhone 6(on which i have tried to recreate the issue) is that the type of blur used gets more expensive by orders of magnitude when rendering more pixels.
alright I am getting real confused with what they are saying. so my app's are running in the background. like when I execute something in pythonista on my iPad pro (12.9). my bioinformatics codes take a 20-30 minutes. I have never had any issues when I execute the code and then I go to watch youtube videos, use FaceTime, tumblr, read iBooks, open 3-4 safari tabs. play XCOM, all while doing a PIP stream from amazon video or netflix. I come back 30 minutes later, or sometimes even later that night, and pythonista has finished executing my code, and the output is there for me to import to iCloud or dropbox.
now if what that guy is saying is true, I must switch away from iPad. But in my gut, i think the iPad is multitasking, else, how is it able to finish execution of the code?
and also using the iPad pro (12.9) made me hate apple because of how great it is. apple has opened my eyes to how great 4gb feels on ios. It made me hate apple because i realized how much they hurt me by putting 1gb in the iPhone 6 plus. I suffered with that phone since the beginning, apps loading out of RAM. ugh most disgusting device apple ever made. I won't say you need 12 gb of ram yet, but i am profoundly glad for 3gb.
I feel your pain. coming from the iPhone 5 to a 6+ i thought it was better at first but its not. No apps stay open in the background if you use another app. Plugging into my car stereo it auto plays and always starts over never remembers the last song. Ram was the worst problem in that phone. happy to have 3gigs coming from a 6+. should be night and day for me.
Dude I am so happy you said it dude. There were so many times where I legitimately wished to own iPhone 5s instead of 6 plus. That stereo thing is especially true. Multitasking was slow. I almost felt like never buying Apple again, but the iPad Pro restored my faith and assured me ios is great. Apple were just being greedy and cheap.
The only thing I've been happy with is the screen and camera really. I'm still rocking the iPad mini 2. I don't know the benefit of more ram yet.
I would guess that it has something to do with the two modems that the iphone 7 is using. The verizon/sprint iphone (GSM+CDMA support) and the T-mobile/ATT iphone (GSM only).
My dear nagromme... Can you afford a REAL phone yet? iphone is the best... not a cheap clone of public domain software. Try it, you will change your toon.
