I've had my Droid X for about a month now. In general it goes about a day before I have to charge it. That seems to be about normal. My questions is in that day of total time, how much time can the screen be on before having to charge. I seem to get about 2 1/4 to 2 1/2 hours with the screen on. That doesn't seem that great, but I was wondering what other folks are seeing.
Thanks.
Depends what else is going on for the phone, and what the brightness is set to (in extremes, what the temperature is).
But, even in the worst case, 2.5hrs is a bit low. I recently got just about 3 hours streaming Netflix, 100% brightness, on a decent cell connection, on my 11-month old DX.
I would expect close to 8 hours on a constantly on screen, just running the clock, 1% brightness, in airplane mode.
Extended Battery
I didn't mention that it was about 2.5 hours, with the extended battery (1850maH). I'm running GB, auto brightness adjustment, no over/under clocking. Push email/calendar/contacts/tasks from our Exchange server. Auto-off after 30 seconds.
Shouldn't I be able to expect at least 4 hours screen on time under this configuration?
Yes you probably should be getting better battery life
The battery on this phone is generally good, but some things drain the battery more than I think they should. Standby drain is great (3-5% overnight) but the screen murders the battery. It drops 1% every 4-5 minutes of light tasks such as browsing social media and Chrome, but the drain gets much worse with anything that's more demanding on the processor. For example, 23 minutes of gaming on my PS1 emulator killed 10% of battery, and just 13 minutes of Crossy Road killed 6%.
Is there any way to improve battery life when the screen is on, or is this normal power consumption for a 2k display like this one? For reference, I have it set on auto brightness at the lowest setting to save battery already. Also, my phone gets 4-5 hrs SOT with moderate usage and maybe 30min-1hr of gaming. If it's the latter, I'd take a 1080p screen any day for better battery life...
Turn the brightness down.

I said I already have it set on auto brightness at the lowest setting
Turn off auto brightness. Other than that, the screen is going to draw a fixed amount of power. Also, resolution has very little to do with how much power the screen uses, it's all panel size and brightness.

Pretty much the only knob you have is display brightness.

I thought resolution has everything to do with how much power the screen uses? The way I understood it a screen with a given resolution has the same amount of pixels whether it's 5.5" or 5.7" or some other size, hence phones with different size screens but the same resolution having different PPI's.

I turn it on only when I'm outside. Aside from affecting power draw due to brightness, does auto brightness also draw extra battery from having to operate the light sensor constantly as well?
Other than that, I've already been doing everything you guys have suggested. Do you all experience the same type of drain that I do?
The backlight is the primary power user in the screen. It doesn't care if there is 1 pixel or 5 million. The GPU will use more power at higher resolutions, but a 5.5" FHD screen will use nearly the same power as a 5.5" 4K screen.

But OLED displays such as the one on the Turbo 2 don't have backlights, so the higher the resolution, the more pixels the battery has to light up and the more it drains the battery?
The pixels are smaller, and there is less power use per pixel than on a lower resolution display. Will it drain more power? Yes, but the amount is likely negligible.
What I would recommend
I know a little about a lot, When it comes to Android phones and phones in general,
The auto brightness feature always has an effect on battery life I always tell people it is much better to set this manually and to change it when it's needed. Also more modern phone os's allow this setting to be toggled quite easily. As to what screen panel uses more power I don't know a lot about that but I would have to agree with the idea that the higher the resolution the more power it draws. Good luck to you and hopefully we see marshmallow soon around the globe!
Okay. I've also noticed that the screen drains power a lot slower once battery level is below 30%. Has anyone else experienced this? Regardless, I'll calibrate my battery today and report back if it makes any difference or not.
You could also try Lux, it has a lot more options when it comes to auto adjusting the screen.
Anyone tested this themselves? Didnt see it mention in any reviews.
I don't know but it must use close to nothing; the thing is to darn dark on this thing, I can't barely see it. It was a lot brighter in my Note 7, it's useless now.

Not dark at all on my screen. I don't seem to see it moving around at all, though which is concerning to me.
From https://www.notebookcheck.net/Samsung-Galaxy-S8-Plus-SM-G955F-Smartphone-Review.213438.0.html :
The Always-On display is pretty efficient. The smartphone only consumes 0.13 Watts during standby and 0.23 Watts (on average) with the Always-On display.

On the S7 edge the guys at samsung told me that 1 hour usually takes about 1 percent of battery. Don't know wether the S8 uses the same amount or not. That doesn't sound that much, but at the end of the day this would be something about 10-20 percent.
Gonna get my S8 (hopefully) today - so I can test it.

most of what i read people said it was closer to 1% every 2 hours on the s7.
I've got it on
All day
All night
Battery life, while not amazing, hasn't been affected by aod
I keep it on. Most of the time the phone is in a belt pouch and the AoD shuts off when it is in a pocket like environment. The only time it is really on for an extended period of time is while sitting on the wireless charger.
I keep mine on too. Here's my battery life. That's Bluetooth, location, always on display, and high performance settings on.
2 Gmail accounts that are synced (constant work email), Facebook, messenger, GroupMe, Instagram, Snapchat. A few text messages since most of my chats goes through social media.
It is a shame (as far as i can tell) that the battery usage meter does not separate "screen" with "always on display".
My thinking is that the OLED screen is not back lit so it is only each individual pixel using power and since the screen is mainly black this is not a lot.
When the S8 is in a brightly lit room the always on display is brighter lit so will use more power. In a dark bedroom it will use less.
AoD Informal Testing
The official Samsung line is that AoD uses up about 1% of the battery per hour. In other words, AoD will use up about 24% of your battery in 24 hours. That seems to be close to my personal experience with the S7, but it's hard to say. I believe my phone uses about 2.5% of the battery per hour with AoD off, and about 3.5% / hour with AoD turned on. I'm still getting over 24-hours of battery life per charge with AoD on.
There are some comments here along the lines of "it can't use too much battery, because it's so dim" or "it's in my pocket most of the time, so it's not using power." Keep in mind that some of the battery AoD uses is that it turns the proximity and light sensors on every minute or so to determine what the brightness of the display should be, and whether it should be on at all. AoD mode likely uses slightly more battery even if the phone is face down on a desk and not displaying anything.
Some people have said they don't use AoD because they can't see the pixels moving and they're worried about screen burn. I believe the pixel movement is very subtle, and the image doesn't move all around the screen. It just moves enough so that the same pixels are not always being used. When you unlock the phone, then lock it again, the AoD will appear in a completely different spot on the screen and then shift subtly around that same spot. I've been using AoD on and off for 2 years with my S7 and I can't see any trace of screen burn.

The pixels do most def move I have witnessed it....
I use my aod when its dark normally between like 8 pm and like 1 times im up at night other than that I dont use it
I read some where on the gear watches about aod and the strict limits samsung has in place to prevent burn and battery waste.
As fast as these devices can charge battery should not be an issue for any one any more lol
Update: Just wanted to provide an update to this. I ran some very basic tests on both phones at the same time such as browsing, checking emails, a little gaming, etc. And what I noticed was that the G6 actually performed slightly better than the OP5 for normal use, and of course this is more important than a constant video playback test. And based on what others posted below it makes complete sense now why the OP5 seemed to be better in this. (Assuming the numbers were even accurate). But in normal day to day use I am seeing the G6 having excellent battery life. Anyway just wanted to update this so it doesnt cause someone to think I am saying the G6's battery is bad. Original post below.
Hello XDA. I just got a T-Mobile LG G6 and LOVE IT, except for one issue. Battery life. AOD is off, and always has been. My other phone Ive been using before this is a Oneplus 5. Ive been trying to decide which phone is going to be my permanent phone and love the G6 over the OP5 in almost every way except for battery life. I ran some basic tests just to get an idea of how they compare. Now I know that the G6 has a 2K LCD display and the OP5 has a 1080p Amoled. But I didnt think there would be that much of a difference since a lot of people said that the difference as far as battery life wouldnt be that much.
So I went into the tests expecting the OP5 to a bit better. But I didnt expect the results I got. The short result is that the OP5 had 20% more battery after running the below Netflix test for 2 hours. I ran the test again the next day, this time for 5 hours and the OP5 had 55% more battery left than the G6. The average percentage loss for the G6 running Netflix was 10% every 30 minutes, while the OP5 only loss an average of 3.25% every 30 minutes. When checking the battery usage to see what is draining the battery the most it is definitely the screen. On the G6 it accounted for 34% of the total loss, and on the OP5 it was only 13% of the loss. So maybe the 2K vs 1080p screen is the culprit after all. Like I said I expected it to be a factor, just not a 21% difference in the total usage between the G6 and OP5.
I also know that my OP5 is running 7.1.1 and the G6 7.0, but as far as I know the main difference between the 2 versions is Doze, and I have Doze off on the OP5 due to a Gmail sync issue. And I also know that a simple Netflix test doesnt really represent what kind of battery life I can expect from normal day to day use. Anyway basically what I want to know is does this seem normal, and when the G6 gets 7.1, or 7.1.1 will that improve the battery life enough to hopefully be better than this?
Like I said I REALLY like the G6 in every way, except the battery life. And Im not giving up on it. So if there is some hope that the battery life will improve that will definitely make me lean more towards keeping the G6 over the OP5. Anyway thanks for any input. Below is some more details on the test results I got. And Ive attached a screenshot of the battery usage with it at 11%, down 8% since the Netflix test ended.
LG G6 vs Oneplus 5 (2nd Netflix drain test)
Netflix Streaming Test at 100% Brightness, no other apps running. No Sim card in either. Both had same settings toggles on also:
LG G6:
Started at 100%
After 30 mins 92% Lost 8
After 60 mins 83% Lost 17
After 90 mins 72% Lost 28
After 2 Hours 61% Lost 39
After 2:30 mins 52% Lost 48
After 4 Hours at 40% Lost 60%
After 5 Hours at 19% Lost 81% (55% more drain than OP5)
Average of 10% loss every 30 minutes (About 6% more loss per minute)
Oneplus 5:
Started at 100%
After 30 mins 97% Lost 3
After 60 mins 94% Lost 6
After 90 mins 90% Lost 10
After 2 Hours 87% Lost 13
After 2:30 mins 84% Lost 16
After 4 Hours at 80% Lost 20%
After 5 Hours at 74% Lost 26% (55% less drain than G6)
Average of 3.25% Lost every 30 minutes (About 6% less loss per minute)
Just wanted to add an update. I decided since the main drain from the G6 was the screen that I would try the test again, but this time adjust the screen brightness on both devices so they look as close as possible. When I had both set to 100% before the OP5 was quite a bit brighter. So this time I had them looking as much the same as I could. The test results were much different.
Oneplus 5 after 4 hours of Netflix had 65% left.
LG G6 after 4 hours had 46% left.
Although its still 19% less than before, its a lot better than the 40% difference from the previous test. So Im hoping by leaving the G6 at a lower brightness will help improve the battery life. And of course hoping that 7.1 also helps. Anyway just wanted to update this. Thanks
Anyway, i think that is not a fair comparisson... OP5 has 1920x1080 screen and G6 1440 x 2880, at least for me, 5 hours of screen is totally awesome, but if LG do something to extend the battery efficience would be great
The OP5 has an AMOLED display. The pixels in these displays actually create their own light. They consume no power when they are black, low power when dim, and quite a bit of power when displaying bright or white content.
LCD displays like the G6 use a backlight with a panel in front that blocks the light from getting to your eyes, creating an image. They have consistent power consumption that is completely determined by the backlight level, the image itself is irrelevant.
TV shows and movies tend to have pretty low white level, so AMOLED displays use very little power most of the time. Switch test to browsing where there are tons of white backgrounds and you would probably see the LG catch up or take the lead.
Edit: Also have to mention that the OP5 is using a pentile subpixel layout. This means that instead of each pixel being made of red green blue sub-pixels like the G6, it only displaying either a red green or a blue green for each pixel. So not only is the OP5 displaying less than half the pixels that the G6 is, it's only showing 2/3 of each pixel.

I'm not sure how you achieved these numbers, but i suppose it's not accurate, specially those on #1 post.
Assuming OP5 has 3,25% drain every 30 min is like saying it has a screen-on time of 15+ hours. No phone could ever get this with actual tech.
Great battery phones, with heavily modded kernels and roms, helped by wakelock limiting apps, could achieve about 8-9 hours max with screen turned on.
So, my guess is that it could be some kind of battery trick on OP5 side (not showing accurate percentage, for example).
Your second test is more feasible, but i really think it's still too much for both phones (about 7,4h SOT for G6 and 11,4h for OP5).
Please don't take it as a criticism on your tests. I'm just saying here that your battery is lasting as expected for today standards.
G6 does poorly/average in these constant playback tests but overall in normal use it manages to do well. Whatever case, in my kind of use, it does really well
Does the G6 have wifi scanning turned on?
OFFTOP: How OP5 and LG G6 screen compare? OP5's AMOLED is PenTile so not really fullHD. Is the G6 much sharper when displaying small text etc? I dunno which one to consider buying
About differences in battery -> remember G6 has older, more power hungry SOC. And it has to much more work thanks to bigger resolution. I would say difference is actually quite small having that in mind and LG did great job of optimising its software.

Im not sure how I got those numbers either. I just wrote down and noted what I saw. The fact that they looked to good to be true, and that there was such a discrepancy between the 2 was why I ran the test again. And it wouldnt surprise me if Oneplus had done something to inflate the numbers. I dont know if you read about it, but they were caught again "cheating" benchmarks by forcing the phones to run at maximum when they detected a benchmark app running.

I decided to do another basic test and just started playing around in apps, games, browsing, etc. at the same time on both phones. And the G6 not only kept up with the OP5 but beat it slightly, and the G6 had my Sim card in at the time, and the OP5 didnt. So what I am noticing is that in normal use the G6 has been great, and even slightly better than the OP5.

Another thing I noticed is that overnight when both phones werent being used that the G6 had just slightly more battery in the morning. So Ill update my post above so people dont think Im just trashing the G6. After more testing, and normal use it seems to have excellent battery. So Im not sure why there was such a difference in the video playback tests. Anyway thanks for all the responses!

This makes complete sense. Especially after my recent tests where I turned the brightness down on the G6 to match the OP5, and when I ran normal tests that I explained in my other posts. The G6 actually performed slightly better in normal use such as browsing, checking emails, etc.
Abnormally high screen on times are not uncommon in video playback tests while on WIFI. This is due to the lower brightness required (low average white level), lower processor utilization (due to hardware decoding), and no interaction with the screen (due to the processor not jumping to max frequency on screen touch).
It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Moto X4 before depleting the battery.
Then, drop a comment if you have anything to add!
I'm getting 6+ hours and true all day use, easily.
Easily the best SOT of any device I have owned... Over 6 hours yesterday and was at 45% when I plugged in for the night. I don't believe I will need to charge this thing at all other than overnight. Amazing!
Crap I'm getting 4 hours at a stretch.

The X4 has a bad cell reception. On wifi i get 7-8 hours but in mobile data only 4h maximum
I was off WiFi yesterday traveling and still had nearly 7 hours SOT by 10pm and 12% battery left. I live in rural Wyoming.
I'm at 3.5 hours SOT, and I'm still at 43%. A good bit of that was relatively intensive. I had GMaps download 3 offline maps covering 5 states, Play Music downloaded ~3GB of music for offline. I logged in and set up a bunch of apps (social media, etc), and played Clash Royale for ~1.5 hours.
AccuBattery says I'm averaging 11.2%/hour Screen On, and 0.7%/hour Screen Off.
Clash Royale is ~13-14%/hour, where both my old Nesux 5x and Nexus 7 (2013) were ~25-30%/hour.
I am extremely impressed with the battery life on this. I can't wait to get a kernel with hotplug and root with Greenify to see if I can't get it down even more.
Update: Over a 36 hour period, I got 5.5 hours SOT, and plugged it in with 12% left. That includes running benchmarks, playing games, and all the stuff I mentioned in the previous post. I'm guessing I could get 7-8hours in a day of continuous light usage, and probably an average of 6 hours SOT with a generous mix of gaming and youtube thrown in.
Overall, I'm VERY happy with the battery life.
Had 4:40hr sot at 51% battery

Background color
Can anyone help me with this question? I read that an LED screen will consume slightly less power the "whiter" it is, unlike AMOLED. So I've been changing all of my wallpapers, backgrounds, etc. to white/light to help the battery life. Could someone add to this with some facts?

That is false. OLED or AMOLED screens are made up of thousands (millions) of tiny LEDs, so black backgrounds save power by simply turning off a portion of the screen when it wants to show black. This is why you get battery saving.
The screen on the Moto X4 is a LED-backlit LTPS IPS LCD. Because the backlight is separate from the LCD itself, and the IPS LCD is an active matrix, there's no way to reduce the power consumption simply by changing the color. The IPS LCD has to use power to change the color no matter what it is, so it's kind of irrelevant. The only change that can (and WILL) make a difference on your battery life is brightness of said backlight. This is why everyone knows to lower your brightness to save power.
If there was a way to segment out the LED backlight into a per-pixel basis, then you could obtain the same battery saving features as an AMOLED screen, but at that point you're basically building 1/3 of an AMOLED screen anyways, so why not just build the whole thing?
An interesting side note, because these phones are using LTPS technology, the LCD itself does use less power than older phones, even at the same resolution. It's still dwarfed by the consumption of the backlight, but power saving is power saving, amiright?
wow, this sd630 is awesome! getting 6+ hours with some heavy wifi downloading, installing apps, making a hotspot, streaming music, watching videos, etc.. why did i ever want a flagship?? my old op3 couldn't get close even underclocked and with a black substratum theme lol
battery life is crazy on this phone. what did lenovo/moto do?
i can use it for social media and some gaming and I'm always on 4g and theres days when I dont charge it at all. loving it.
I got 6+ hrs SOT on 1st day let's see how it's perform in next few days
I am getting 8 hours SOT with moderate usage. However I am using data over WiFi only and no gaming.
battery life is great here as well.
even with 2.4ghz wifi (being at reasonable distance from the router),
browsing on screen time with speakers playing music but not on loudest,
i seem to be able to hit 10hours easily.
best phone battery i've had. (compared with Samsung SII plus & Moto g3rd
(I don't play games on my phone tho so i can't comment on that)
i'm a heavy user but only play Marvel contest of champions on my phone sometimes. Mostly i play youtube videos on loudspeaker with maximum volume, check facebook, twitter, chat on whatsapp etc. And i'm still getting nearly 6 hours of screen on time!
I don't track my SOT but definitely impressed with the X4. I normally charge my phone (and remove the charger) before going to bed (12mn) and until now (it's 2pm here), I still have 60% battery left.
I don't play games but I frequently use my phone for social and media consumption.
I'm not worried that my phone won't last til I go home (~10pm).
With my previous phone (HTC 10/ Huawei P10), the battery percentage may be around 40% by now.
Mine on first charging...
