Faster in what?

Haha. No it wont. But i am talking more about apps that involves a significant amount of user waiting on the cpu processes such as stitching a panorama or rendering a large a large web page with flash.

I read both articles. Waiting for more real world results.

I see what you tried to do there, but it isn't that easy. I'll spending the same amount texting someone no matter what. And being able to load my Facebook 2 seconds sooner does not mean I'll be on there any less. So yes, the extra screen on time is important

Yes. Did you actually read the linked post or just rush to bang out a response? The One X can sustain the display for over 10 hours on a single charge, in specific conditions. Those specific conditions do not qualify as normal use, but they do indicate that it's not simply the 4.7" display that is causing the significant batter drain.

It is pretty straight forward. You're not going to spend an additional two hours loading apps and webpages on the One XL. Both are blazing fast, and the difference would add up to less than a minute at most over the course of an entire day. At most. The difference in time spent waiting over even a first gen Galaxy device would be minute.

But the real issue here is the S4 has a significantly higher IPC than the Tegra 3 and is much faster in single threaded applications. The Antutu benchmark shows the performance of the Tegra 3 in highly parallel processing loads, a very uncommon use scenario, and not at all similar to loading a webpage or app. I can think of very few tasks outside a highly complex game (which would have been designed to run on the lower end hardware that is much more common) that would actually take advantage of 4 cores on a phone.

At the end of the day, screen on time is a very useful metric for comparing battery life. It's hard to say if the One XL will have significantly better battery sign as few people have posted results so far, but some of the early indications are very promising.

5hrs is way more than i'll need. that's at least 2 days of usage for me.

A Cadillac Escalade can get 30MPG going downhill, with the A/C off, in low humidity, and with a tail wind. Would you agree that the Escalade gets 30MPG? I didn't buy the phone as a lab experiment and when evaluating battery life the most valid comparisons are how it does against similar phones and how well it holds up doing what each of us typically do. If the international version gets 10 hours under "specific conditions" than there's a good chance bedolf's will get 14. It's early, but it certainly appears under “typical” conditions Teg3 uses a lot more battery than S4.

This is a follow up battery stats from my previous post here:
http://forum.xda-developers.com/show...05&postcount=5

During the last battery cycle my One X spent about 1/3 time on texting, emails, and other things... and the 2/3 was all youtube video playbacks on wifi ONLY.

Screenshots included with this post show the battery stats of my 3rd battery cycle.

The phone was on LTE the entire time (1-3 bars), auto-brightness on, and just to put things into perspective I collected the following stats as well:
  1. data uage: 337 MB (LTE)
  2. calls: 6 s (lol just for the reference)
  3. SMS sent/received: 125

Edit:
Forgot to mention the things I did during that cycle: SMS, emails, a few youtube videos, web browsing, two rounds of draw something, a couple photos, no camcording, and some other miscellaneous apps.

Edit 2:
Just realized that the usage stats might be more since they only show the usages during April 23. I started the cycle in April 22 evening.

Thank you for the battery stats beobolf. Im definitely jumping ship as soon as my contract with Sprint is up (June).

I think the miss the point. The point of that test, and bringing it up here, is provide a point of reference for how much power that actual display is using. The conditions in that test, in case you missed them, are that the phone was fully charged and then unplugged, the brightness set to "auto", the screen time out set to "never", and the radios were left on. The phone was then simply left to idle until the power died out.

What we can gather from this test, is that it likely not the large 4.7" display that is chugging the juice but likely the hardware feeding it (re: Tegra 3, possibly the GPU portion?). Thus it is entirely possible that the One XL with the S4 would attain longer battery life. How much longer is unknown at this point, though we will get a better idea as more people get this device in their hands and post their results.

I don't think we can expect the One XL to see 14 hours in of screen on time in this test unless we've been given with a larger battery, which to my knowledge we both the One X and the One XL use the same 1850 mAh battery.

Thanks, I see your point. But it brings up other questions. Was it left alone in a dark room with an all white background displaying? Or was it with an all black background in broad daylight? The latter would result in at least twice the display drain. In the real world the display is off unless you're doing something on the phone so the processor will always be active (in some form) when the display is. To me, that kind of invalidates the test. It’s kind of like the international version being crowned “best stand-by life.” Idle on any phone isn’t heavy so a 50% improvement for something that uses 5% of your battery is kind of a hollow victory. With the X and XL having the exact same displays and batteries the XL’s superior performance is either the efficiency of the S4 when it’s working or better driver implementation by HTC/Qualcomm vs. HTC/Nvidia. I’m hoping the latter helps the international version via future updates. The international version is still running a GB (vs. ICS) kernel.

My benchmarks are how well the international version seems to do in aggregate compared to the XL (bedolf is a sample of one), how the SGS3 does when it comes out, and how the One X fares doing the same things with the same apps I used every day on my former i9100 (expecting a reasonable deficit).
