Display Issues

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

Display power usage

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 !

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.

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 have 2 exchange mail accounts set up to push and one gmail account...

Screen battery drain

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.

Switching to ART 16% battery drop

This is probably a rough test but how much battery did you lose when you switched to art if you did? I was on 32% battery when art had finished switching over I was on 16% that's some drop, I know the CPU and ram must have a lot to do but come on.
The battery life I've had from this has been dire, I've been over the apps, I've lessened and lessened everything, I literally can't cut back any more, so the prospect of seeing 3 days etc just isn't going to happen, hence why I switch to ART runtime instead, I wanted to see if there was any gains, and yet in the time it's taken me to write this post, I've lost 2%.
Please can anyone clarify that this is happening to them too?
I'm coming from an S5 and i thought that was OK, but on the note 4 the battery is awful.
Will see ART out for the day and see how it goes.

In testing ART too but need to run a full week to get a real fell for performance and battery changes.
As for the switching drop, it's normal to lost 15-20% as all apps need recompiling but it's a onetime thing (unless you restart your phone), in which case it'll do the same again. So, don't restart!

Haven't restarted m8, but the battery is etrocious from what I've seen up til now, I haven't even rooted.

Well you had to have restarted when you switched to Art, otherwise the change wouldn't have been applied. That explains your battery drop, so nothing to worry about there.
As for battery life in general, my non-rooted Note4 consistently gets about 5-6 hours of screen time and about 25 hours total run time. Note 4 battery is pretty good actually. Check out the battery life threads for comparison and see from there. Maybe something up with your particular model or a rogue app draining battery.

It was in reply to the previous user who said "Unless you restart"
Anyway, battery life is slightly better, I got 1 day and 20 hours with light ish use, so i'm happy with that, I have turned power saver on though.
And it isn't an app trust me, streamlining a phone is one of my strong points.

AOD huge battery drain

Hey guys.
So I noticed everyone here and anywhere else basically, complaining about the battery life on this phone after the MIUI 11 update so I used the debloater directly after getting the phone to have the best battery life possible.
Turned off all the suggested apps and services and I gotta say battery improved, but it wasn't what was promised by the phone's specs. I'm barely getting 4h SoT, without any heavy usage whatsoever, only social stuff.
The culprit for me as well has been the Android System, with over 40% drain every day. So I installed Accubatery to try and see what's happening with my battery, along with better battery stats.
What I found useful from the accubattery app is the permanent notification where it tells you, after a few seconds, how much mA will be drained in an hour of using the phone like the way you are using it at that moment. So I did a test. Had my phone on the home screen, doing nothing. After a few seconds the reading showed -180mA, which is awesome right? Then I locked my phone and left it at the always-on display for a minute or so. Unlocked it and the notification showed -980mA.
This is very VERY weird and I cannot find anything anywhere suggesting what anyone can do to combat this. I have more average battery drain when the screen is off than when the screen is on.
I have never reset my phone (and would like that to stay that way if possible) and the phone itself is a month old. It's really saddening to see other people are getting twice as much SoT.
Do you guys have any suggestions?

I was on Miui 11 for a few weeks and had ~8h SOT with AOD enabled all the time. Now I am on Pixel Experience and I have ~7.5h SOT without AOD so I am very satisfied with the battery life.
I advise you to wait for Miui 12, which will come very soon to the Mi 9T. Then everything will probably change again with the battery life...
