I was just wondering how lowering the phone's resolution works. Since they claim lowering the resolution will improve battery life, do you think it will also improve performance?
I've personally never felt the need of 2k resolution on a phone, so yeah. If anyone has any info on this, could you please share?
Performance will improve a bit, but battery savings probably won't be very noticeable.

Does anyone know if using a different render effect in Cyanogenmod (ex. Calibrated (N1) Cool) has any effect on battery life?
And would turning off surface dithering improve battery life noticably?
I've asked these questions in other threads but haven't seen any responses so I was hoping to find some here.
Thanks!
been wondering the same thing. anxious for an answer. i also want to know the benefits of surface dithering
Well I personally leave it checked, but unchecking surface dithering will decrease the picture quality to an extent, and this decreased performance, so thus should increase battery life. And again, I can't give your actual numbers.
Hi there. I have tweaked my phone for extra battery life (custom ROM, kernel, undervolting and multicore power saving) and I would also like to improve performance further more without reducing battery life.
The g3 has a 2560x1440 display or something ridiculously high like that. Its practically the double of 1080p. My PC monitor is 24 inch and has a 1080p resolution. Even though without antialising I can see pixels, its still pretty good. In my opinion, 2560x1440 is way too high for a 5.5 inch screen.
Since 2560x1440 is the double of 1920x1080, reducing the resolution should greatly improve performance. http://www.phonearena.com/news/We-c...and-negligible-battery-life-increases_id65982
However, resolution changer pro and NOMone resolution changer either do not work or cause a bootloot on blisspop 3.6.
Does anyone know of any similar ROMs or alternative apps that will work with blisspop?
Thanks!

Decreasing the resolution will certainly increase performance and is also helping me to get the rid of the heating issues that I have faced on my G3. Resolution Changer Power Menu would help to decrease resolution efficiently. But I am not sure how much it would work with blisspop .
@tristan6100 hi. you can change the resolution manually using terminal:
su
wm size your_size
wm density your_density
if something fails you can try:
su
wm size reset
wm density reset
Especially with root now becoming available, I started giving this more thought:
If someone wanted to do that, would running a lower resolution be an option, to perhaps extend your battery life?
The screen is QHD, 1440x2560. To minimize scaling issues with a fixed-pixel-location screen like an LCD, you could go down to HD, 720x1280. Now the graphics hardware is dealing with 1/4 as many pixels. It won't look as good, granted, but lets say the user accepts that trade-off.
Is this even possible? If so, do you think it could help battery life?
I don't have experience with this on phones. But on a computer, you can certainly lower your display resolution, even if using an LCD. It will look fuzzy at a non-native resolution, but perhaps that's less of an issue here, with the pixels being so small by comparison. And if you were gaming on the PC, lowering the resolution would allow higher framerates, assuming you were limited by your graphics card, not your CPU. I've admittedly never thought about it from a power-use perspective, but it seems reasonable that, if keeping the framerate the same, running a lower resolution would require less power for the PC.
My Galaxy S3 was 720x1280, admittedly on a smaller 4.8" screen, but I thought it looked fine. If using a lower screen resolution could, say, add 20% to my G4's SOT, I would be interested in that.
I believe this is what changing the DPI is for. This can be done via apps, or changing the value in the build.prop I think. Pushing less pixels on to the screen will definitely increase battery life. There's a threshold though, and depending on which G4 variant you have (whether it's branded by a carrier, etc.) you may want to research on what a safe number might be. I think some AT&T G4 user reported bootloops after changing the DPI to <530 or something. It looks like the camera doesn't get affected by the DPI change too, which is a definite good sign.
I'm waiting to see how the battery life holds up right now with root mode now being enabled in Greenify. If I can't squeeze more than 5 hours SoT while at a certain brightness and using BT, I'll consider changing the DPI.
This is not going to improve battery life in the slightest. You might be running a lower resolution but all the pixels are stilled turned on. The lower tax on the GPU is negligible.

Agreed. This was done on the G3 and batter life was not changed, only game performance improved as you are pushing graphics at 1080p instead of 1440p.

I believe that that's wrong, specially if you set it to numbers lower than stock.
I found a way to change the resolution

Follow this thread, it's so simple and works perfectly!! on LG G4 818p
I Get Exactly 50 Hours of Battery Life Even When Watching YouTube. These Themes Are In High Quality Serving Better Battery Life And Performance. Why Not Give It A Try?
50 hours is really something great. The most I was able to survive was 16hours.....
Where can I get them?
1. Themes can't increase the performance.
2. Use any dark theme to increase the battery. This works because our phone has an Amoled display. Google for more informations.
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.
