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

My phone is off a lot of the time but it still uses up a lot of my power according to the battery use screen.
For example, right now my battery is at 45%, 9h 15m since unplugged. "Display" shows up at 48% of the power use. Time on is 58m. On my old Evo, Display was rarely on the top of the list. A day like today would have Cell Standby and Phone Idle at the top taking up over 50 - 60%.
Could it be the auto brightness setting that's sucking power? Anyone else getting these results?
I haven't had the time to try and figure out why, but yes, I am getting the same results on mine as well. Right now the battery is at 44% (9h 42m on), with the Display at 55% (1h 33m display on). Display has always been at the top of the list for me. The next three are Android OS 13% (1h), Cell Standby 13% (9h 42m), Phone Idle 8% (8h 14m)
Mine has been unplugged for about 1.5 hrs, and on for 35 minutes.
Voice Calls: 45%
Display: 33%
Cell Standby: 8%

I use a power widget to scale my screen brightness as needed. I'm usually on the lowest setting since I'm mostly indoors but I had it on 100% all day yesterday since I was outside and it wasn't really draining my battery.

I too keep mine on the lowest setting as well. It's plenty bright enough for me. Also, I wouldn't trust those readings...it could also be related to the whole false reading of the reception and battery status symbol. Perhaps software related. Nevertheless, the screen still uses 20% less power than traditional lcd's.
Try keeping it off auto brightness and see how it does...should notice an improvement.

You mean 20% less then an average AMOLED? and then AMOLED is 30-40% over LCD
Guys... You WANT your screen to be the highest thing using battery. It doesn't mean that it is bad. It just means that the screen is taking MORE battery than other things. You need to take it for what it is. A comparison versus other items on the phone. Your screen using that much power is how it should be (think about your laptop... turn the screen down or off, battery goes right up). If your screen was at the bottom, it would mean that the actual PHONE was using a ton more power.

Good point. I'd rather have the screen eating power than say, the GPS. But I guess as long as the phone gets you through the it doesn't really matter, does it?
Does turning off the "Powering saving mode" option under "Sound and display" seem to help or hurt the situation?

Indeed.
Most of the GSM models have display at the top, while CDMA have standby and idle.
This is due to CDMA radios drawing a lot more power.
I too am experiencing the same thing... my battery life has been less than stellar, so I have taken it off auto-brightness and am using a black wallpaper to try and reduce the consumption. After being on for 4 hours, (I had to reboot several times this afternoon) my display has used 70%, the next down is cell stanby at 12% I was fully charged at 3:30 today - it is now 10 and I am down to 33% battery remaining, with moderate to minimal usage.
I guess a gorgeous display requires a lot of battery.....
Battery use has to add up to 100%, so something has to take a majority. 66% doesn't mean it took a huge part of your battery. Imagine this, you unplug your phone and then go on pandora for 15 minutes of the first 20 minutes unplugged. Say your battery was at 96ish by then. If you checked your battery usage and it said something like PANDORA: 75%, it means that pandora used 75% of the 4% that has been drained, not like pandora has some type of abnormal battery sucking bug in it (key word abnormal, i'm aware pandora wears on a battery). But get the gist? If it were "cell standby" and "phone idle" that were using the battery, then we'd have something to worry about seeing as the phone wouldn't even be in use during its times of most power consumption.
You people apparently never actually TALK on your phone. My voice calls take most of my power.

I can't quote this enough for emphasis.
Use your brains folks. If your battery is lasting all day and your screen is using half of your power draw, then you simply have a far more efficient phone than before.
And over the EVO, that makes a TON of sense. Your WiMax OFDM radio probably used up a higher percentage of your total power draw because it simply uses more power than our WCDMA UMTS radio.
Be happy - not disappointed. It means your battery is mostly being used up only when you actually use the phone as opposed to eating up all of your battery while it's just sitting in your pocket.

Rather than wasting time with not so clever posts, maybe it would be more beneficial to read the first post a bit closer. If you're not using the device a lot, you would expect the Display usage indicator to decrease over time and the other indicators such as Cell standby and Phone idle to increase over that same time period.
Hi Guys,
I am on Roto JMI v2 and noticed that the battery consumption on Display is around 60-70% all the time even at minimum brightness and power saving mode. Is that normal? Help?
Cheers!
I am on stock and it's always on 83%, so you are better off. My guess is this reading shows the total battery consumption and not the current battery usage.
Normal. Same for me.
Hey thanks for the reply guys was really confused since read on xda a post where the guy mentions 20% usage on overcome rom

its not a bug, the display is what always eats the battery in devices.
Another thing that puzzles me is that whether I have the brightness at MINIMUM or I have it around 35%, the phone still showed the same %age of battery consumption. So does this mean irrespective of the level of brightness, it is going to consume that much of juice or increases with level of brightness (which is only logical) ?
Also, it seems my battery usage gauge is all messed up! Even after around 5 hrs on standby and intermittent usage, it showed 12 m 5 s. Very strange!
When you set the LCD brightness to minimum, current still run through it to operate, if not it will be totally blank (as in darkness). So, 35% is good enough.
My personal opinion, the battery status is always a bull, I'd never trust it, after experiencing so much battery issue prior to my upgrade. I would just enjoy the fun of owning the tab and when it's time to upgrade (to another tab), nothing else matter..............
So long as it kills my time (by playing games, listening to music, watching youtube), improve my efficiencies (by having the necessary apps), keeping in touch (emails, facebook, Skype, phone calls, etc) and most importantly, it is extremely portable. Other than that, I just charge it before I go to bed.
It serves my daily needs. I am happy.
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 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.

Hi,
I recently flashed my G2 to the leaked T-Mobile gingerbread release: so it's not rooted or anything like that. I'm not using it any differently to how I was before.
The upgrade went very smoothly. However, the battery seems to be draining a lot more quickly than prior to the upgrade, and Android's battery usage app points a very damning finger at the display: currently it's showing 67% usage, and pretty consistently shows a high usage most of the day.
Before, I could consistently run the phone for the whole day and charge overnight, but now I'm finding that I have to charge it a bit during the day too in order for it to make it to the night.
I'm pretty sure that I'm not using it any more than usual, and I pretty much always have brightness set to 20%.
So my question is, what could be causing this? Could something be using the screen when it's not supposed to be even though it's not showing anything? Could it be a battery calibration issue? Maybe the power usage app in gingerbread calculates what it attributes power consumption to differently to froyo (though that wouldn't explain the overall reduction in life). What, if anything, could I do to try and track this down further?
Any suggestions would be appreciated!
Some things I should add.
I really haven't changed my behaviour regarding how I use things like wifi, bluetooth and gps. In fact, so far I actually have one fewer gmail account set up on it that before the upgrade, so sync should be doing less work. The apps I'm using are all about the same.
When I said I could use it for the day, I mean it would often end the day with more than 50% battery left. On some days I'd get it down really low, but that would be due to obvious extra usage, which isn't the case here. Occasionally I'd let it die completely. I always charge it fully overnight.
Finally, here are the other top items in my power consumption list at the moment:
Display: 67%
Maps: 8%
Cell standby: 7%
Phone idle: 5%
I seem to remember that before the upgrade, Cell standby and Phone idle were usually the top users of power.
no problem
Sorry, but I don't see any problem. Maybe its just placebo. This is the same on every android based phone. I Had HD2 and had 2 NAND androids till now and the battery stats were showing also display use 60% and then after new NAND version - gingerbread they were up to 80%+ but the battery was better than ever before.
Let me explain it to you. The display should consume most of the battery if you have 3.7 inch display and more. Maybe some navigation and 3G is the biggest sucker like the display but with normal use the Display. And if your display consumes lets say 75% of battery over when you are at 1% battery then it means it sucked 3/4 of your battery and just 25% other things did like phone idle and cell.
If it was before and your display consumed like 40% or less that meant that the other things like cell standby, phone idle consumed more power so it wasnt battery efficient. So its more battery efficient. Maybe you just have much more awake time than you did before. The awake time - sucks the hell of your phone(some apps warn you taht your phone wont turn to the sleep, which means your processor is still working hard which means your battery will deplete completely in a short time)
I experienced this also that my phone lasted only 6 hours or so and before it could wen to all day . Then I deleted some apps which were causing it and my battery was perfect.
and last advice. try to charge your phone via USB, I dont really know why it is caused but it will last longer , but on the other hand you will have to charge it longer. But if you go somewhere where the extra juice is needed then its nice.
With these steps my HD2 with old battery (about 1000mah left on 100%) went through 2 days of medium USE and about 5 days of just receiving calls and messages) so I dont know anyone else who could say that !
ยจ
hope I helped you. GL a HF
If you can stand it, turn the brightness as low as you can handle . EDIT, you're already doing that....hmm
Not sure why gingerbread is giving you problems, personally I find it slightly better with battery than froyo.
Sent from my T-mobile G2
Hmmm... placebo. By that, I presume you mean that since Display is ranking higher in the list now, that's making me think more battery is being used before. I suppose it's possible, but really it's more to do with how often I've been reaching that "I should charge" point, which for me is a function of battery level and time. If I get to 50% before lunch time, I think "I should charge". But getting to 15% just before bed I don't. What I've noticed is that since the upgrade I've reached the "I should charge" point every day.
I'm just very surprised by how the proportions in the battery usage list have changed, while a the same time the phone's battery usage seems to have increased, despite the fact that Gingerbread's battery usage is supposed to be improved.
One other thing that came to mind: perhaps Gingerbread's battery usage is just more accurate than Froyo's? It always seemed to me that the battery level used to work a lot like a car's fuel gauge: it would stick at 100% for a long time and then would drain. It was as though "full" as a concept understood by Android was a range rather than a limit, and so as a result the phone appears to drain more quickly, but it's actually just showing a more accurate battery level over time. Just a theory.
So last night I allowed the phone to completely die. This morning I switched on and immediately checked battery usage: display showing 99%, which is exactly what I'd expect. So I'll see how it goes now that Gingerbread has experienced battery exhaustion.
Personally, if I was upgrading from Froyo to Gingerbread, I'd prefer to start from scratch rather than doing an "in-place upgrade". I'd worry that maybe there are some leftover settings or files from Froyo that could cause unintended consequences. Consider backing up as much data/apps as you can (it's more difficult if you don't have root), charging the battery up to 100%, doing a factory reset, and then restoring and reinstalling everything back. Doing this will also reset Android's battery stats file, so you may find your battery levels maybe inaccurate while it's relearning the right levels for a few days.
Alternatively, if you don't fancy a factory reset just yet, you could try monitoring your power use with a widget like CurrentWidget which looks that the current draw rather than percentages. Also consider installing Watchdog Lite which might be able to help you identify if there are any processes using excessive CPU cycles.
EDIT: Just realised that if you flashed a leaked version, the install would probably have wiped everything anyway, so you can probably disregard the first paragraph.
Like the others have said, I think the screen usage being higher in 2.3 has more to do with the reduced usage of other apps and not the screen using more battery than in 2.2.
Think about it, most of the high battery usage items (web browsing, etc) also keep the screen on at the same time.
Yes, that's probably mostly because other things are using less power. I also suspect that maybe Gingerbread's battery usage app is calculating display usage differently: I just checked it on someone else's G2 (still running Froyo) and Display was way down the list. It dominates mine, even though I haven't used it that much today.
Today's power consumption has been a lot better. It's down to 39% now after 12.5 hours on battery, with 59% of that being attributed to Display. So that's not bad at all really.
Thanks for the tips on the monitoring apps. I'm already using System Panel (which only seems to care about apps and not hardware so much), but it's always worth checking out alternatives.
Couldn't it be due to you being in areas with bad connection?
I noticed that my G2 is down tot 30% after a few hours at school in bad reception+bad wifi areas. When I'm home the whole day my G2 is still at 60% at 10pm.

I am using the cyanogen mod 7, and I have a 3500 battery. My battery will go down 1% every 203 minutes most of the time, and my battery usage always says the display is taking up 80-90% of the power. I have talked with others using the same rom and display takes up 4% or so for them. Obviously something is wrong with my phone.
I have updated to a better kernel, etc. etc. Turned brightness down, and nothing reduces the amount the display uses.
Any ideas?
Mine uses 80% as well, but isn't that normal? It's always been at least close to that. Sense ROM's report it differently and it's usually really low on those. Unrealistic, because the display uses the most power of anything on the phone. Especially when displaying white on my AMOLED. Doesn't use much if everything is black though . But it doesn't matter on the SLCD model anyway.
Pretty sure the percentages CM7 reports are closer to reality. The display is what uses the most power, if your apps are chewing through your battery then you've got problems. I thought battery drain was worse too at first, but it just reports battery usage differently. Make sure you don't have any apps constantly syncing or causing the phone to stay awake (even when the screen's off).
The problem is my battery goes to 75 in like 30 minutes. Something is killing it
haha I see now I made a mistake in my original post. It goes down 1% every 2-3 minutes I use it, which means it is about 3 hrs of usage, with a 3500 battery. that is horrible. I even installed the incredikernel.
If you use the FB for Android app, check to see if it's running, my battery was getting destroyed by something, checked to find out FB had not stopped or opened itself and had taken 75% of my battery even with screen off.
Still rocking the Incredible with the XDA Premium App.
You most likely have an app that's constantly syncing data.
