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

Battery life?

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

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...

Display battery use 67% Normal??

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.

SyndicateROM Frozen (EB13) - Battery Life Thread

Hey guys,
Just created this thread so we could all have our battery life info in once place and keep the dev thread from getting cluttered.
Please post the following info:
1. Standard or Fully Loaded version
2. Total hours unplugged and percentage
3. Details (percentage and time) for each service
4. And any pertinent details such as apps used (juice defender), or extended batterys
Also, please don't forget to calibrate, airplane bug fix, and kill that drm.
Ex. (will edit with final time)
1. Loaded
2. Total - 8h50m @66%
3.
Display - 55m 78%
Cell standby - 8h50m 9%
Wifi - 6h40m 7%
Phone idle - 7h54m 4%
Voice - 1m 3%
4. Juice defender, setcpu @ 100/1000
Ideally we want to wait for a full drain to post stats but this is just an example. Thx guys looking forward to seeing what you all are getting.

Just installed it will get back to you in a couple of days after recalibrating my battery.
Btw, i hear Juice defender does more harm than good...

Interesting. I think you are right, we are essentialy minimizing out idle drain to a certain extent. However, even activily using my phone it drans slower than stock with this rom. My next run ill try and use it all day to see what I get.

Battery drain
Hello everyone, noob here. I can't post in the development forum on this but it pertains to the battery and charge to a degree. Maybe someone here can help me in some sort of way.
I rooted and flashed the SyndicateROM Frozen yesterday, used it all day and never a hiccup. This thing is lightning fast and props to the dev's but here is the only issue I found. This morning after waking up I noticed the phone was stuck on the ACS android startup icon. I plugged in to charge last night and it's like it froze the phone when it reached full charge. Anyone else experience this?
Thanks for any help that I receive.

I think I read in the dev thread that it's a known problem with the kernel? Or maybe it was the rom... or CWM? anyways the dev's know about it. Just don't charge your phone when it's off.
Battery for me seems to be a lot better than stock, but I'm always charging here and there... today I'll let it run without charging for 4-5 hours and I'll report back. Using a lot of setCPU profiles.

Are you charging it with the power OFF? Lots of people were posting issues of freezing when charging with the battery off --- and I think the probs are related to CWM -- not the ROM. Only charge while the phone is on -- and you should not see problems.

I put on to charge with the power on last night because I had set the alarm to wake me up and it never did so that is when I noticed it. I don't think I've ever charged it with the power off, even when it was stock.
Maybe the dev's will come up with a fix sometime in the future. As for now, I'm happy as hell 'cause this ROM is great.

Did this just happen once? If it doesn't happen over and over, I wouldn't consider it a bug. I have only heard of issues like you describe with the power off.

I'm looking at 12 hours on ACS Frozen on average. I haven't even gotten close to the rumored 30 hours with "heavy use" I think my use has been moderate. My battery use log only only lists display 98% and cell standby 2%. This confuses me. I do more than sit there staring at my homescreen.

How you use your phone makes a difference and while 30h is possible, I don't see it happening with heavy use unless that is little display use. Below is my most recent "heavy use" run. Basically tried to use the phone all day, xda app, browsing, mainly wifi, 0% screen brightness.
1. Loaded
2. 8h7m @5%
3.
Display - 5h33m 95% <- serious display use which kills the phone quick
Wifi - 4h56m 2%
Cell standby - 8h7m 2%
Voice - 4m30s 2%
4. Setcpu @100/1000, juicedefender, 0% brightness
Pretty good considering the insane display usage. With normal use I get over 20h so that just shows how fast it kills your battery. Going to do an "extreme" run next to include heavy cpu use (play emulators all day haha).

You did that with a standard battery? I haven't seen anyone post more than 4 hours of display "time on". That's impressive. Maybe I should try 0% brightness. I have mine at 25%. Are you on "Conservative" on SetCPU?

The 98% means that 98% of your battery use is coming from the screen. Click on where is says 98% and look at see what the use details are (the "time on"). Generally, most people are getting less than 4 hours of display time on with a single charge. The explanation is that some people stretch 4 hours of display time over 30 hours of use. In other words, the people who are getting 30 hours of use only have their screen on 10 - 15% of the time (or less).

Yes, using the standard battery. Setcpu is on conservative. I always use 0% as it looks great (kick it up tp 25-50% outside). I think I was able to get that long of display use due to minimizing cpu usage and other services. All I did is browse in dolphin and use xda app. And, that was pretty much all on wifi. Only change was the hour I was at the dog park on 3g and I recorded a 5 min video.
I bet my gaming session tomorrow will kick it down to ~4 hours

With phone calls, texting, and music player, I average between 16-18hrs. If I start to web browse or watch videos then about 8-12hrs. Very impressed with this ROM to say the least.

1. Standard
2. 31 @ 5%
3. don't have that it was yesterday
4. standard battery, auto brightness, overclocked to 1.2, wifi on when I was at home and 3g at work.
I calibrated the day after froyo dropped. I didn't do the airplane thing and I thought drm was not in this rom. So in other words I didn't do any fancy stuff.
I will note today I tried 1ghz (which is undervolted) with 4G on all day (I have a repeter on my roof at work) and after 14.5 hours I am at 30% with about the same concistancy of usage as yesterday.
Edit: I only have 1 gmail syncing right now. We will see if I get these magical numbers when I put my other 2 gmail accounts and my 3 actice sync exchange accounts on Monday.

I'm getting mixed battery life. The first day on the rom/kernel I dropped down to 79% in 9 hours, with medium use (no web browsing). I was getting 1% drop every 1-2hrs, and thought it was amazing. Today I tried to be really conservative and didn't use it at all and it dropped 4-5% every hour WHILE IDLE.
Anyone else experiencing the same problem? It seems to happen after a reboot to be honest.
NOTE: If I disable data network mode, battery life is amazing,

I'm not sure about my battery life. I charge mine differently than the average person though. I charge it at work and leave it in my desk, because I use it a lot during my lunch break or whenever I get any downtime. When I get home it's usually at about 70%, and it remains unplugged until the next day. I used to have to charge it at home and at work.

CM battery use

On stock my battery use would indicate display as the most used item under battery use.
On CM, however, cell standby and cell idle I think takes up 43 and 40 percent respectively while display only takes up 5 percent... is this normal? I thought on a highly efficient system, display would usually be the most taxing power draw item.
Any input would be greatly appreciated.
P.s. big ups to toast and the CM team for making it happen!

Similar situation here, though mine shows display at 15%. I seem to have similar overall battery life as I did on stock though.

For the most part, unless you never turn your screen on, display should be number one
Sent from my PG06100 using XDA App

I see the same thing as the OP, however I find that my battery life is improved in CM7. I am running Nightly 35 right now, but it was pretty much the same in RC4.1 as well.

Still testing but looks the same... phone idle and cell signal take up the most but display is now 10%.
On stock I got 48 hours off a charge if I stuck to wifi places. It would be 24 hours in and id have something like 56percent left.
On cm I'm 8 hours into this experiment and have 44 percent left.
Sent from my PG06100 using XDA Premium App

I've also noticed my battery life isnt near as much as it was with a Sense rom. I looked today after reading this post and realised it said I was 59% time without signal when I havnt dropped service once. I wonder why that is... Hopefully they get this figured out as I really liked how CM6 gave my Hero more battery life over stock not the opposite.

My cell standby is right at the top with 37% but my time without a signal is 0%

Ok day two of testing coming to an end... I tried the suggestion of turning on airplane mode this morning then off to see if it made a difference.
Off the charger at 8am
At 15% 10:28 pm
Cell stand by 32%
Phone idle 25%
Wifi fall in the middle here somewhere
Display 5%
Still not the kind of batterylife I got on stock. I just goto school and home these days pretty much same routine everyday and constantly on wifi.
I'm gonna try to set the clockspeed down from default of 1ghz in cm to 800 to mimick stock tomorrow and see if that makes a difference. Then maybe try a new kernal like x99 later on in the week.
Will report back!

I'm getting better battery life, by quite a bit. But I just noticed I've been running at 800MHz under the "conservative" governor, so that explains part of it

how's the responsiveness on the conservative govener? Any lockscreen lags or anything?

I haven't noticed much lag if any. Except occasionally when opening some apps, not enough that it ever really bothers me.
I switched it to run at 1209 MHz, and I can just about watch the battery percentage drop, so there's a definite difference there
