Just did a factory reset. ( Replaced Feb 1 ) 2 weeks used.
PC Mark is the only app installed.
ROG 2 Ultimate Edition.
PCmark work 2.0 benchmark battery.
I will run the same test with 120Hz and full brightness and come back to you. But...
I will have X mode turned off. The reason for this is that you don't know what settings others have applied to their X mode.
I will also activate flight mode. If you're in an area with low reception and have apps that constantly send/receive data, then this will have a severe impact on the final result. It's better to just remove this uncertainty from the equation so there's no reason to question the result.
So I recommend you to run your test again with X mode off and flight mode active
Btw @Anders they recommend to use 200 ca/m2 - nits ? on the brightness level.
As I don't have that kind of equipment to detect the nits or candela.
I just assume to use 100% brightness.
Does x mode have default settings? Can they reset that?
When you say low reception? does it also apply on the Wifi Module? and not the Mobile Data?
Anyways I will try your setup.
200 nits is their standard for this test but then you need to wait forever for the battery to drain. At full brightness (indoors) the screen is closer to 500 nits. I forgot to say that you should disable adaptive brightness too.
When I say low reception, I'm mostly referring to mobile data and I see you have good reception in your case but this might not be the case for someone else who wants to compare and this is why we must all use the same settings.
X-Mode does have a default setting that normally does very little. It basically increases the thermal policy but PcMark is probably white listed which means that it will also overclock or to improve performance. There's also the possibility that someone else has played around with the X-mode settings for this app. If we just remove it from the equation by not activating it, then we don't need to think about it.
So the test should look like this
FYI, the app will change its orientation depending on which test that's running. So it's very easy to accidentally terminate the test by swiping from the wrong side. I did this after several hours of testing when I wanted to check the battery life ?♂️
Hahaha happened to me too.
I just slept and let it die as i expect it will somehow end near 6 to 7. And it's right!
I have the features that needs to be done and here is the result.
Let me know if you put up max volume too.
I really having suspicion on that speaker battery drain.
Also if you notice my performance go all the way down without x mode.
Ah, sorry, I forgot the volume level. Set it to +1. Yes, full volume does drain the battery but you won't want to listen to the phone at full volume for hours and hours. The reason why I don't just set it to mute is because +1 will activate the circuit and drain the phone a liiittle faster.
Here's my result but it's worth knowing that I had it in my pocket between pass 14 and 20 when moving from home to my work. This made the performance throttle which underclocks and draws less power. I also had only +1 in volume which will increase battery life.
So we're not that far from each other.
The room temperature will affect the battery performance so if you have 27 celsius and I have 23, then that can make a small difference too. This goes for charging as well.
If your device truly reaches 88% charge in 1 hour, then we can log your device to verify.
Great find. But my volume is at max
how do I log the phone?
Thanks. Great output.
But I noticed a difference of 30 mins and mine just passed to PASS 30 and yours ends in PASS 40 to 50.
I guess the consistent 40c throttled the device?
i'll do a retest but with + 1 sound.
Anyways I wanted to know how do you log the phone while charging.
@Anders_ASUS also take note that the replacement phone is just 2 weeks old and an ultimate edition
@Anders_ASUS here is the new result with +1 volume
xtomylee, please don't make up your own settings. The whole purpose with this thread is to sync our settings. If you set your screen brightness to 75%, there will be a bigger difference in our results than if we test at 100%. I'm not saying 100% is entirely fair as there are brightness variations between displays but it's easier to compare at 100% than 75%
It's also important that we have X-mode OFF.
Please use these settings and surrounding conditions
Sunlight or a very bright desk lamp may put the display in overdrive and increase the brightness to above 600 nits.
In my second test without throttling, I reached 7h and 30 min. For those of you who haven't used PCMark before. This test runs from 100% to 20% so it doesn't matter what the battery percentage says in the screenshot.
Ok, gonna check it after work.
Is there where the claims of 626 nits is being used?
"Sunlight or a very bright desk lamp may put the display in overdrive and increase the brightness to above 600 nits."
What lighting environment did you have while testing?
Can you give us reference on why the bright light do overdrive on the device brightness?
Btw here is my screen on time.
My test all day using the phone - 5hrs 54 mins of SOT
System Lighting off
No Aero Cooler
Only using Lightning Armor Case.
How does the battery life time affect the temperature.
It's impossible for me to get that temperature without Air Conditioning.
I'm leaving in the Philippines which doesn't have that kind of temperature.
But i'm guessing the ambient temperature in my place is about 32 to 36 Celsius.
The reason why mobile phone displays have an overdrive is because you don't need to have a very bright display under normal indoor light conditions. The displays are not designed to stay in overdrive mode for a long period and it draws a lot more power so this mode can only be accessed when the phone detects strong light.
As long as you don't leave your phone by the window or put it right under a very bright desk lamp, there's no risk for the display to enter overdrive mode.
The testing scenario above is so hard to replicate that it doesn't help. I want to know what battery life you get when you run the PCMark test with the exact same settings. If you can't reach at least 7h then we know your battery has lower capacity but you did reach 7h at one point with full volume so I'm interested in knowing what you can reach with the exact same settings and testing conditions?
I tried to run that test. But if I am correct you have to kill all apps and run only the test. I had to use other apps as well so PCmark was interrupted. I will leave the phone do it overnight.
But I used phone in those conditions just to see what the battery life would be.
Screen 120 Hz
Airplane mode off (I need the connection)
I played Asphalt over 3 hours. Results are devastating. I guess it's the screen set to max brightness responsible, apart the fact that my eyes are now destroyed by the brightness.
Here is the screenshot
Practically the phone was finished after 3 hours playing Asphalt. That much less then playing Asphalt in X-mode but with adaptive brightness on.
I would like to comment on the X-mode. With it turned off, the phone didn't heat up at all. Max temperature was 42 Celsius. Also 39 C for a long time. Notably less than Samsung Note 8 after playing 3 hours. That phone would glitch much sooner. CPU was running stronger (over 30%), while GPU was running lower (average 80-85%) than in X-mode. Didn't notice any decline in smoothness of the game. So with X-mode turned off it's absolutely fine to play without Cooler attached.
I don't understand why the system reports Asphalt 1%.
I will try again.
Here are my results. Settings as required by Anders
Sound volume +1
Screen 100% brightness
Adaptive brightness off
I would say results are quite good. The battery was 19% and good for another hour and 35 min.
