Not long after LG posts an official teaser for its upcoming QHD G3 smartphone, leaked press renders hit the web

Late yesterday, LG posted a teaser video of its upcoming G3 smartphone which gave some fleeting glances at the phone including close-ups of its image stabilized rear camera. You can see the video here:

Not long after, however, Phone Arena gave us the full goods by posting leaked renders of the actual device. The G3 will be available in three colors: Gold, Titan Grey, and Silver. The close-up shots also show what appears to be a brushed metal backplate, but Phone Arena states that this could very well be a traditional polycarbonate shell textured to look like brushed metal.

The phone’s most talked about feature, however, is its 5.5”, 2560x1440 (QHD) display with 538 pixels per inch (PPI). We’ve already heard from Huawei Consumer Business Group CEO Richard Yu that QHD screens are “nonsense” and “a stupid thing,” but Toshiba obviously sees some benefit in this display "arms race."
Other reported features included a Snapdragon 801 processor, 3GB of RAM, a 13MP rear camera, and of course the latest version of Android 4.4.x KitKat.

To get complete details on the LG G3, we’ll have to wait for its May 27 official reveal.

I understand that actually. The overall point I'm actually trying to make is that when you understand that, you realize that you can make the phones even MORE efficient by not upgrading the resolution. You may not be losing (net loss) battery life with each new model, but it's not as good as it can be. In many cases, it could be way better.

I'm not arguing that we should all go back to 640x480 so we can have extra battery life, just that the tradeoff for going to 1080p->1440p isn't necessarily worth it for what little gain you have in visual quality.

OK, granted... But everything you mention is pure theory as we have no data to show what the penalty is. Real data isnt out there, becasue you would have to test the same exact phone on 2 differnet res's and that isnt testable outside of an OEM's lab as you mentioned...

Based on how every generation increases the res and gets more efficient at the same time it must be a very small penalty.

Hmmm this has me curious. How DO we figure this out? Outside of the debate with inighthawk, I'm now genuinely curious how much more does rendering higher res truly impact efficiency?

My gut feeling is, not much. But he does have more experience than me in this field.

I HAVE pulled up how much actual power the individual smartphone displays pull, that was easy. It's VERY low.

However that tells us nothing of the actual GPU consumption of one res vs. another.

Also this is only LCD's, no OLED's :(

I'm not sure it would be possible to do (test accurately) without having different panels. I would normally suggest using a tablet and setting the resolution to a lower setting, but you will still run into inaccuracies since there may be hidden work associated with non-native resolutions behind the scenes.

Windows has a feature called ETW which allows you to take a trace of the system as it runs and collect performance information through various events. You can then open the traces in various tools to visualize the data. There is a tool called WPA (Windows Performance Analyzer) which can break down some stuff such as GPU utilization and power state info, and another tool that ships with it called GPUView, which can visualize the actual workloads submitted to the GPU itself (every packet of work sent to the GPU). You can view how long a particular workload actually takes.

The biggest problem is that you are unlikely to get super accurate results, since the tracing itself can interfere with the system and provide results that aren't necessarily what would be real-world results. It may wake up the CPU more often and/or do additional work, or may make the display driver behave differently just by enabling it. It may still provide a semi accurate view, but I still wouldn't use the results as much of a baseline.

The alternative might be to get a tool that measures power usage and use the same scenario of lowering the resolution on a tablet. I think that would be more accurate, but then there's no way of knowing if the resolution change impacted anything else.

The other thing to consider is the workload itself. You'd have to choose your workload carefully to ensure it simulates real world usage, and do it long enough to matter. Rendering the windows start screen, for example, is going to be a whole lot simpler than random apps from the store. Other random apps may also put more drain on other components such as wifi. But I don't think this is stuff I need to point out, you seem smart enough to realize you're not going to get an accurate test by letting the device idle :)

Basically we cant... Just buy the phone you want with the features you want... If you don't want over 1080p, and there is a phone that suits your needs with 1080p, I would say buy that phone. If you don't want over 1080p and the phone that that meets your needs has a 1440p screen, buy it anyhow.

I am 95% sure on getting a G3 regardless of the res. (unless something better comes out between now and its release) I dont personally care if the 5.5 inch screen is 1080 or 1440, I am getting it for everything else it has, and I am 99% sure the battery life will be even better than the 2013 pack leading G2.
