Ill make this plain and simple, im having really high display percentage on my N1 and i cant figure it out. As u can see the picture below, the display % is at a 81%!!! and here is the thing, i have only 4 widgets running. At the time that i took the pic i had the brightness at 30% but even if i have it at 0% display % will always be around 60-75%.
This is what i have on my N1:
Rom: cyanogen 506
Kernel: persiansown uv-oc
So this being said, this display problem is affecting my battery. i get an average of 12-16 hrs which its pretty good, i think but i used to get 32-36 hrs. Can anyone know what could be the problem? Cuz im totally stumped
do you keep your screen on for long periods of time?

oh no, i turn it off when i dont use it. i have the screen timed out at 2min, 1 min, 30sec, ect.. and still get same results.
correct me if im wrong, but i think the battery status (usage) is staggered. Meaning itll post every thing that uses the battery and will display in percentages and will total to =/- 100%.
So if the rest of the phone is only using 19% then your screen would then display around 80%. Lets say the rest of the phone is using 50%, then your battery would then display around 50% of battery use. But its still using the same power consumption with the two instances.
again, correct me if im wrong, i briefly remember reading that somewhere. Cause i guess someone had been using the phone with 50% brightness and when he decided to put it at about 10% he actually increased 2% on his display usuage. hahaahha!

On Desire ROMs it's only 17%.. or sometimes lower. I don't really care though.. Lol.
It is all relative, always adding up to 100%. If you're phone/wifi/3g/cell percentage is really low, then the display will be really high. The higher the display is shows how good the rest of the system is at conserving power. The display is the largest battery drain on the system. If something else was higher, or even close to the display use after you've used the display for a while I'd be scared something was wrong.
Let's say you charge your phone, never turn on the display, and leave it sitting for 5 hours. Then check percentage. Cell idle, Android OS, and things like that will be the largest, totalling 100% battery use. But your battery may only be down 10%. Then use it for an hour with the display on, display will suddenly jump up to 80% and everything else down to 20%.
Or in other words. Let's say you have used 20% of the battery (battery level is down to 80%) On the battery usage screen display takes up 90% of that, and the rest of the system 10%. That means out of the 20% you used of the battery, 18% was used by the display, and 2% by everything else.
People think Cyanogenmod is bad because the display is so high compared to other mods, but it means that the rest of the system in cyanogenmod is actually more power efficient than the others. So display will naturally be higher relative to everything else.
I believe this is a known issue with 2.1
so i guess in a way its saving power,right? since it is not didtributing power all over the place.
i think its because of the Screen AMOLED is probably a battery eater, i think its fixed and its called Super AMOLED
Does having usb debugging on effect battery? I left it on today and noticed horrible battery life, phone was at 15 percent at three pm lol, minimul usage. I am running a over clocked undervolted kernel woud that have something to do with it?

I'd guess the overclocked kernel is your issue. Also, check your battery usage in settings and/or spare parts to see anything that stands out. If you have high cell standby usage or a high running time, that would also be a culprit.
I've been running OTB Test 5 1.3 for several weeks now and have great battery life, much better than stock. I would look in your battery usage to see whats using up all the battery like imnuts said. High cell standby drains battery really bad so if thats up there then I would start using airplane mode more often.
Its at three percent. Airplane mode is not an option, then I could miss important texts correct? And not be able to use internet right? Yes battery life is horrid right now. I tried using set cpu to lower cpu during screen off time an my phone just shuts off when the screen is off for any length of time. I do run my screen at 100% tho.. Might just try a different kernel

Profiles in SetCPU don't work on our phones. They cause it to freeze, like you're experiencing.

Is there a reason you need to run at 100% all the time? That's probably your biggest battery drain.
At least try setting to auto.

Alright I did *22899, charged to 100%, turned off and charged again till 100%. Booted then booted into CWR, proceeded to wipe batt stats, Dalv Cache, and Cache Partition. That was at about 1am, went to bed and woke up at 9:30, phone off charger all night and it was at 75%.
Cell standby 41% T/O 9H 50M time without 0%
Screen brightness is up because thats why I bought the phone, this screen is awesome. Battery life was never and issue before I rooted and started with the roms and kernels.
Best I expect with all the antennas on except bluetooth is 7-12% drain overnight. The number one battery killer is the sAMOLED display.
It is rich in contrast and pleasing to look at. The screen resolution is good but a tad grainy. They say the pixels are off when black, but a slight glow is always detectable in a completely dark room (boot up your phone in complete darkness, the black screen looks different on than off). It can also burn in, so I recommend hiding the status bar up top or at least switching to 24h time to prevent the M from burning in. back to topic, there is nothing magic about it for battery drain though. You can do alright if you always work in black background screens, but in many cases you are doing worse than an LCD. Don't expect more than 2.5 hours of active use in the best circumstance if you leave it at 100%.

(note GOS since this is propaganda, but the chart is interesting. It implies that our screens burn up to 1.13 watts when full white, which can be 50% or so higher than similar displays. It also contradicts my statement that black pixels are always on)
Apologies again for straying from topic. The display was the main factor that made me pick Samsung, and yes I do like it.
Swyped w/ XDA App. When in doubt, mumble.
51% at Noon after moderate use, did a nandroid back up and flashed a theme as well. Theme I flashed is pretty dark and high contrast, so I'm gonna tone down the screen to zero percent, charge it back to 100% and see what the rest of the day is like. Also have had GPS and Sync on at all times as well, going to try it without those for the rest of the day as well.
Do you guys use auto sync and background data? I don't think I really need them, I don't really care about my facebook push notifications, but do care about email...
Since I've upgraded to EB13, my battery usage details for "Display" have been a lot higher than normal, even when the screen is used very conservatively, it seems to always be in the 90%'s. I have my screen brightness locked on the lowest setting. The screen brightness is more than high enough when indoors, even at the lowest setting. Is there a mod or hack to lower it even more?
Before, when on DL18, even when my screen on time was high, "Display" was never in the 90%'s, and "cell stand by" was more than my current 5%, haha.
Please post your "Display" battery usage detail percentage and what android version you are currently on for comparison.
*edit* I am running midNIGHT ROM 4.1 and Genocide EB13 0.3a kernel
Pretty sure this is a bug. I always have my display set at the highest setting and I am getting like 2-3x less screen on time per battery charge. Not worried about it yet since I have a backup battery, but it is certainly something I will keep an eye on.
If your using undervolted kernels, the display will have a higher percentage because the CPU is using less, while the display uses the same.
Its a bug in eb13. The "Battery usage" in the settings always shows my display @ 90%. I don't trust it anymore, cause it is now displaying inaccurate information
Sent from my never been rooted, stock Froyo Epic.
Since eb13, all, mine shows is display and cell standby. No wifi (use it all day) or anything else. Seems to be a useless graphical representation now.
I used to enjoy the decreased brightness kernel for 2.1. I'd love to see that mod in a froyo kernel.
fwiw, I'd also love to see supercurios sound mods...
Do you not use your phone for actual calls? Mine shows:
Display 70% - 1h 7m on
Voice Calls 12%, 18m 5s on
Cell Standby 11%, 0% without signal
Phone Idle 5%
WI-FI 1%
This is after 12h 21m unplugged
Download an app from the market called Screen Filter. Let's you lower brightness a lot more, great when you're in bed or something for example.

I have noticed this too, I swear its lumping more than just the screen into the "display" category. I use the display at the lowest brightness possible, and even with the screen on for very short periods of time display is usually using 70-90%
I noticed this on DK28 also, seems to be something different in how samsung records battery usage in froyo.
My current time - 16h 50m from unplug @ 100%
DISPLAY - 65% (51 m, 9s)
Cell Standby - 18% (4% TWS)
Phone Idle 9%
Voice Calls - 5% (4m 41s)
Wifi - 4% (1h 58m)
Currently 18% total battery left
No where in here is the several hours of music/podcasts that I listened to at work today accounted for. Seems like our battery meters aren't telling us the whole story.

Awesome, that works great with the use of an app.
Would still be nice if the devs incorporated into their kernels for EB13 like they did in DI18 though.
Whenever I check my battery status, my display is always at 45%. Is this normal? I still get good battery life, I think. For example, I been unplugged for 6h and 18m and I'm just at 70% battery remaining.
I don't know what to tell you; if you aren't doing a lot of CPU intensive tasks, the battery should bbe good for hours.

that's kinda strange, not cuz you are always stuck but because you are showing 45%. I thought the atrix only measures by 10s.

That is exactly what I was thinking. I've never seen anything but increments of 10%.
No....I'm not talking about my battery percentage, I'm talking about my display percentage. Its always the higher of the four...wifi, phone idle and cell standby is always low, like in the single digits low. But the display is always high. Like for example I woke up this morning, checked what was consuming battery and the display was at 65%. If the phone was sleep for the past 4-5 hours thus the display not being on, the display shouldn't be consuming that much battery, so I thought.
I still get great battery life. Im just wondering if anyone else display is also consuming a lot battery and what could be causing it.

Ahhh, ok. I get what you mean now. This is normal for most Android phones with large (4" or bigger), bright screens. As long as you are getting good battery life you are fine. I'm assuming you keep your brightness set to automatic?

Considering you are getting good battery life and your display has that high of a percentage after "sleeping" that long is a good thing. That just means the other processes are running efficiently. You should always expect the Display to take up at least 60% of your battery, especially after a full cycle. What really matters is actual runtime.

Ok...thanks. I was just wondering.
I'm curious if anyone else is having an insane battery drain just from Using the screen. this is my first Android device after switching from an iPhone so I'm not sure if it's normal but with auto brightness I still get 60-80 percent battery drain. I have a Us AT&T version of the S4.
Having a 5 inch 1080p screen will be the biggest battery drainer on the phone currently im getting 3-4 hour screen on time which imo is amazing

If you're looking in the battery stats then yes, the screen always consumes the most battery out of everything.
Its when an app consumes more battery then your screen you've got some problems.
Its really not insane battery drain, its normal if your screen is on all the time. think of a laptop that s not plugged in it will go for days or hours sitting closed with the screen off but still on but with the screen on it draws a lot of power and your battery life soon goes down to 4 hours.
The percentage it is telling you is also misinterpreted. Its not telling you that 60%-80% of your battery is consumed by the screen
Basically if your battery is at 80% and its saying 80% of the battery is used by the screen its telling you that so far out of the 20% currently used of the battery 80% was by the screen and 2% by facebook and 6% by browser ect.

Screens have always been the biggest drain on a mobile device (laptops included). If you want to minimize this (even though it is absolutely normal) you can try going to the Power Saver settings and enabling the "use low power Screen" or something along those lines. I've set that on mine, noticed a bit of a life increase, haven't seen any difference in the screen... so seems like a win-win situation.
