[Q] 5 minute record limit

I know that devices that can record UHD and up will limit the record length to 5 minutes. The main reason that im reading is because of heat. My sisters S5 did get hot after a few minutea of UHD recording but my note 4 doeant get nearly as hot. In fact i cant tell the difference between full HD and UHD when it comes to heat.
I was reading the other thread that it is not a good idea to remove the limit. Well back then we were talking about Snapdragon 800 and 801. Wouldnt the 805 be able to do the same task with less heat?
I actually do have a Cinema 4K T.V and want to record longer bits of video such as my kids sports and other school activities. What do you guys think... good idea or bad idea?
I assume rooting is required to remove that limit.

Are there many drawbacks to running at Max resolution.

I have went back and forth with the 3 different resolution settings. If I look hard I can tell a little difference. At HD it is actually a little less sharp then my LG G5. Do we have any idea of the draw backs of the highest resolution? How much less battery life. Does it affect smoothness. I'll try different setting myself but was just wondering if anybody knew already.

I'm in the process of trying out the higher resolution too. I'll report back my real world use findings.

Does use a bit more power BUT a lot more RAM

I haven't measured battery use (and it would be hard to have exactly the same test conditions anyway), but I haven't noticed any real difference between FHD and WQHD in normal use. I also don't see a whole lot of difference in sharpness or image quality, but maybe someone with younger eyes than me will see a difference.

Testing max resolution for a few days now, no major battery life impact so far. No lag either.

I've been happy with the battery on max as well. At the end of the day, with almost 4 hours screen time, my battery was still 40% yesterday. LTE most of the day, some wifi.

The difference between 1480x720 HD+ and 2220x1080 FHD+ is around 20 minutes battery time over the course of the entire day I believe. Then with 2960x1440 WQHD+ you're probably looking at losing 40 minutes of battery throughout the day. And overall, each step up uses more RAM, which is expected.
In terms of a difference, I can't really tell the real difference between 720p and WQHD+ ... I mean, the screen is small already, it's a phone. It isn't like you're stretch the resolution over a Monitor or TV where you can clearly tell the difference.
I believe WQHD+ is just slightly sharper. The big difference is if you were to use a VR Headset since the screen would be very close to your face and magnified.. this is when I would recommend using WQHD+ ... FHD+ 1080p is fine for daily use and I doubt you would be able to have a noticeable battery drain.
It's truely a topic of Battery Life & Lower Temps / vs. / "Visual Fidelity" & Higher Temps. I believe using WQHD+ over the course of a year would have a considerable but not horrible wear on the battery lifespan however, considering hardware isn't impervious to aging.

I've played with both resolutions but haven't noticed a difference neither.

Will lowering resolution increase battery life?

The settings allow you to lower the resolution. I lowered the resolution to 2340 x 1080 and I don't really notice anything different.... Would this increase battery life? If so, how much?

It will definitely increase battery life.
How much will it increase depends on your usage and your apps installed. It should at max give you 10% increase.

It is well and widely known that lowering resolution won't give you increased battery life. At all

Ah thanks. I come from an xperia z3 so been using FHD screens only. I was interested in the XZ1 compact back then and one of the key points from reviewers is that the lower screen resolution(720p) saved a lot more battery vs the XZ1 at 1080p.

I think the misconception is lowering the screen resolution vs a device that maxes out at a lower resolution. Maybe it makes a difference for OLEDs...but for LCD screens, all if the pixels are still illuminated, so there's not much difference there.

Sounds convincing and makes sense. I wonder why they'd allow it on this device though?

Because Samsung's can do it.
Nothing but hype for the misinformed and ill-advised.
[Dopey voice]"Bruh...look what my phone can do to save battery life. Can yours?" [/Dopey voice]

Using lower resolutions use less power bc they use less gpu computational power. Youre not saving anything really from the screen itself. Think of it this way does your computer/laptop use more power running resource intensive applications or running idle?

As one said here it's from misinformed people.

Not that the resolution that saved power. If Sony could put their 3840x2160 resolution display into 4.3" size of XZ1 compact it still would run longer on battery than any 6.5" sized phone from similar battery even with 720p display. Because it's sheer size of screen that saves battery, not the resolution. 4.3" vs 6.5" is hefty difference. One needs more light to make 6.5" display emit light than to make 4.3" one hence one need more power.
Think about it this way, if resolution would matter then XZ Premium and XZ2 Premium would drain their batteries in a matter of minutes with 3840x2160 res displays. Right? But they work almost as long as say Galaxy S9 Plus or Note 8.

It not works like that. When your phone renders picture in 720p or 1080p it doesn't do it sitting idle. It still consumes power when rendering picture 60 times a sec. And its GPU still runs at 200MHz, maybe it needs like 230 or 250MHz for rendering picture in 1440p but is 250MHz vs 200 MHz a huge difference? I doubt it
It's not like 1440 picture rendering needs full GPU power but 720p or 1080p can be powered by idle GPU. Never was, never will. Ask devs in http://forum.xda-developers.com/android/software-hacking if in doubt

In reality ability to pick your resolution for battery life is a gimmick and doesn't really do anything.
There were no proofs that phones live longer from same charge when it's resolution lowered. Maybe it works for constant gaming, like playing games in 720p on a 1440p screen will bump battery life. But in other cases no

Taking only power consumption from the display alone, there is no different between HD, FHQ, QHD. The different is that if a game or any apps(or even system app itselfs) runs at HD, it will need less graphic computational power than running at QHD (once again, its not about the drainage from the display, its from GPU).

in reality, it's bull****. learn how GPU works. Try to ask Google devs if you don't know. They do habitate here, at XDA
It's not like it renders something and then goes to sleep turning cores off as CPU does. Instead GPU renders frame 60 times a sec and uses 203MHz either your resolution is 720p or 1080p. It can't lower frequency to 100MHz magically because it's not designed that way. So it consumes as much power working at 203MHz either rendering 720p frames or rendering 1080p frames.
Hence no battery economy achieved

In-game performance issues. But why?!

Hi there! I have a Galaxy Tab S4, as you can imagine. I use it as my gaming device. The only game I play is Rues Of Survival. And well, Among us, but I don't even take it into consideration as a demanding game.
The tablet is not rooted but I debloated it with adb as far as I could. Android 10 on board.
Probably this crappy game became so poorly optimized that the performance degraded over time.
Now I am at a point where it's pretty unplayable even if I lower the resolution.
Let's see what I have tried so far.
I have checked the usage of CPU, GPU, temp and FPS with the game launcher plug-in. I have an average of 60 FPS with an average CPU usage of 8% and an average GPU usage of 80%. The problem occurs during crowded scenes. The FPS drop to 30, making the whole thing sutter really hard, the CPU usage stays the same and the GPU usage drops to 60%. WHY THE HECK?!
I have tried a couple of different resolutions (the game does not specifically states to how many pixels correspond each d*mn option) with close to no improvements. The graphics got really ugly, obviously.
Should I try to root and disable DVFS? Should I root and lower the resolution of the whole tablet to a normal fullHD with terminal? Should I stop complaining? Should I quit playing? Should I get a new tablet?
It seems pretty absurd that a game that I was able to play on my Galaxy S6, now got so demanding. Or that a 500 euros tablet aged so badly in two years.
Are those 2 free GB of ram out of 4 not enough to handle the game?
I can play it quite flawlessly on my OnePlus Nord. But this is NOT an option. The hardware specs of the two devices should be comparable. What mostly changes are the screen resolution (lower on the OP Nord) and the ram size (double on the OP Nord).

I doesn't try that game, but I played others (pubg (highers settings), stardew valley, this war of mine... etc), and I have not had problems at all. I'm stock. Have you try game booster?

Question Any way of forcing the screen to 120 Hz?

Hey, so I bought this phone around a week ago and while I love its hardware, I'm having real trouble getting it to move smoothly.
Specifically, I noticed that the screen drops to 60 Hz or less in many apps (confirmed through developer options), slowing down things like the drop-down menu as well. Now I understand that YouTube and most apps do not support more than 60 Hz: however, I do not understand why the phone slows down the scrolling and the notification menu as well. I previously had a One Plus 7 Pro that remained buttery smooth in the menus, even when running YouTube.
Is there a way to force the screen to 120 Hz for Vivo phones? I have tried a lot of the options which work for other brands (tried Setedit, ADB commands, SmartHertz etc), yet they do not do anything on the X80 Pro.
Did anyone manage to force the refresh rate in any way on this phone or on another recent Vivo phone? I haven't been able to find much for X80 Pro specifically.

None so far, and all the apps support 120hz unless coded differently.
On mine ROG6, ALL apps works at ALL the refresh rates, on the vivo however, Youtube and spotify stuck on 60hz no matter what, it's purely Vivo's fault and i hope they'll fix it in the upcoming updates.

I hope they fix it soon as well, my Vivo is laggier than a midrange phone in daily use, despite having stellar hardware and great results in benchmarks. Certainly didn't expect that lol.

Yeah me neither, still shocked how slow it is compared to any phone, actually.

I am on W30 funtouch OS 12.0.12.12 and I noticed that Show Refresh Rate is now showing 120 Hz all the time if 120 Hz is selected in settings. Even Youtube is at 120 Hz which is great. Even in Smart switch mode the refresh rate only toggles between 60 Hz and 120 Hz . In essence LTPO has stopped working and I did not notice battery drainage as such so I am happy also due to concerns on LTPO safety on eyes and the phone feels fast irrespective of whether an app supports 120 Hz or not

I had to choose 120 Hz specifically, when I used "Auto" mode it was down to 60 Hz in e.g. Chrome/Brave. Now it's 120 Hz there. Only app I can see with 60 Hz are games and youtube.

Latest SmartHertz version now supports manual modes, maybe with forced mode it will work on Vivo. Try it!
