Why is my DISPLAY eating 80% of my battery?

So my battery has been great since switching to bangster's build. I loved it. Only thing that confuses me was my "about battery usage" status. It shows that my display is eating the majority of my battery. Any idea?
I'm using the latest tmousa radio. My setting is always 25% dim and no animation. I don't have live wall paper nor any widget that requires constant update.
I've attached a screenshot to show my status.

How did you get that screen? Then I can compare. I'm sure it's correct and probably normal if you think about how big it is. All those numbers are relative to each other. Your screen is going to take up the majority of your battery compared to apps, regardless of what it's set at. I bet if you set it at 100% brightness, the percentage will stay about the same.

Mine has always had similar readings regardless of build

i also got 80% ? even when i turning off the brightness :-D

Mines doesn't ever seem to take as my much but my android system does.

Wow my screens sucked sorry lol
but after about 50 mins my display was 16% and my system 60%

80 percent is pretty high.
These are my stats after being off the charger for about 8 hours. Even if I had my screen on and playing on my phone all day I have never seen dispaly that high on mine.

Maybe the app you're using isn't working correctly on the HD2 (what is that, taskkiller x?)
As long as it's a minor inconvenience like that I wouldn't worry about it...

I was running dark stone's build before this and I remember system taking the majority of the load so I was just concern about my display setting.
I have task killer but not set to autokill. I'm stumped on this. Maybe it is normal since my battery life is better than ever.
Maybe I should post this question in bangster's thread to see if other users of this build experience similar things.

Yea i used some free one called screenshot, looks fine on my phone not when I uploaded it. I feel my battery is pretty good coming from a Sprint touch diamond whose battery is horrible and being that I use WiFi a lot.

The screen using an average of 80% of the battery is nothing unusual. I have just checked mine and after 13 hours I have 58% of battery power left and the display has used 75% of it.

How much do you use your phone a day?
Mines is weird. I am already at 82% and it's been only a few hours off the plug.
What the heck? If you check my signature, I think I have a decent build. Ugh. ANy Ideas? PLZ!

Battery moniter?

Can someone recomend a good moniter for the battery. My battery seems to die really fast the past couple days and the stock battery screen doesn't seem to be very different than when I first got it.
I'm looking for something that showss me stats, not something that tries to conserve power automatically.

There's an app in the desire forum, circle battery mod for non-root users (it shows up on the left portion of your status bar) It works well if all you want is a true number reading.
If you want statistics for what's killing your battery, the Spare Parts app has the best output I've seen.

Battstatt is very nice. There's a free version, and a paid version.
A less convenient, definitely free method: Dial *#*#4636#*#*. This will bring up the Testing screen. From there you can go under Battery information and see a bunch of information about... the battery! Including percentage, time since boot, temperature, ...

Battery Indicator free is in the market and doesnt use any battery while running. Everything else I tried used a little battery up. I use the circular battery version that smoothtaste is talking about and its awesome. It is based off of battery indicator but cant be found on the market anymore. I have the APK but not sure if I can upload it even though its freeware. If its allowed I can get your a copy of it.
Edit: Here you go

You can download juice plotter and it graphs battery drainage over time.

I went from battery indicator pro to battery notif. Smaller size and same icon in notification bar but doesn't give much in the way of stats.
Plus I can see the battery level without unlocking the phone.

I also use that, it doesn't seem to hurt my battery any. The free version is ok, but I opted for the paid version and haven't been disappointed.

Bad battery?

I did the battery calibration and everything and off the charger my phone maybe lasts 4 to 5 hours not being used. So I'm thinking a bad battery? Running the latest Syndicate frozen

If you're on EC05, a bunch of people are complaining about bad battery life. I think it's because the auto brightness settings are pretty bright and need to be toned down a bit. That's my guess, but it might be something deeper.

Sorry child, but my battery life is worst with ec than eb with the same set up. I think most people are comparing their battery life between various updates using the same setup. If you don't see a difference then so be it, but if a lot of people see a decline in the battery life then it's something that people may want to know so they can decide if they want that version. If it's due to more brightness then it's still a setting that's not what you may want.

When I received EB13, my battery life was way worse than D18. The battery would drain in 5 hours with no use. I finally reset it, and it was like having a completely different phone. Everything worked like it was supposed to. I can have wifi, gps, and auto-bright on at all times with no battery drain. I stopped running Advanced Task Killer this time around as well. My friends didn't believe me, but here is my battery after 24 hours. This is normal use...slacker to and from work (40 minutes total), check email, txt messages here and there, and a few phone calls.

What do you mean you "reset it"?

I was going on 34 hours and still had 43% remaining after light/mod use. I use ultimate juicedefender with auto brightness. Even had GPS enabled the entire time. I updated to ec05 using the thread from androidcentral and don't use any custom roms.
I find the battery life slightly better with ec05 along with my wife's epic.

Are people testing their battery life before or after installing extra system tools? I was burned on my last Android phone after realizing automated task/cpu/etc apps were doing more harm than good. Nowadays I just run stock, with some apps removed, the launcher replaced, and brightness managed manually, and I rarely struggle with my battery life (my biggest enemy is the weak signal at work).
It somehow reminds me of driving with your windows down to reduce the fuel consumption of the A/C, just to cause the same problem with drag.

I initially did Menu, Settings, Privacy, Factory data reset and then I did the following just for the hell of it since I already did the factory reset. Figured it wouldn't hurt.
1. Turn off your phone.
2. Hold the volume down, camera and power buttons until the system recovery screen appears.
3. Use the volume keys to scroll to wipe data/factory reset and select that option using the home key.
4. You will see a warning on the screen telling you that you are about to reset your phone and erase all your personal information.
5. Press the volume up key to proceed. Press the volume down button to exit and not reset your phone.
6. After the reset is complete, use the home key to select reboot system now.
7. Your phone will turn off and turn back on.

Nexus S battery

Hi did anyone experiance this kind of battery consumption? 3days 14hours and 45min and still have like 7%?

Not personally, I use my phone too much to get that kind of life out of it. Based on what I know about the drain when it's screen off and sleeping, though, I think it's well within the realm of possibility with light use.

I get like 24 hours out of mine... with some light-moderate use... used to be better when I bought it but then after installing some apps it just starts degrading a bit I guess

Well, rechargable batteries do degrade over time, and the more apps you have on a device, generally the less time it will last on battery, partially because those that run in the background consume more system resources and partially because those that update data in the background will keep your phone "awake" more of the time.

If I wasn't using my phone and just let it idle (sync on, airplane mode off) I'd get like 12 days of battery life. That's what I like about the NxS, unlike other smartphones it does actually last longer when not used.

hi
i am getting around 10 to 12 hours. wifi always on. mostly watching youtube videos. netbrwosing. gaming.
2g phone calling
still i think i am getting reasonably good back up

Disabling wifi,gps,bluetooth and reducing screen brightness will improve battery life.

That's no issue, but working as intended.
Other phones are using the same technique, but they are hiding it by showing the 100% the phone never reached, that's why they drop to 95-97%ish right after unplugging and from there drain normally.

I experienced battery drowning after using app's like maps or latitude. I had to kill them manually, now I'm cleaning the phones memory regularly. That safes a lot of battery life for me on the one hand, but on the other hand loading app's isn't as fast as before.
It's the classical trade-off between battery life an usability. And 10-12 hours are normal for me if I'm using my phone a lot.

Well, depends on the manuf. if they want to "hide" it or not, they could also set 95% capacity as "100%" displayed. All batteries got a safety feature of some kind

in 2g idle it lasts ~14days

9 to 13 hours ,was looking at getting maybe better battery but dont think theres one

So 95% is the new 100% because my phone won't charge to 100%. It just stops at 95%.

My charge wont last even 2 hours screen on time.
Pls help me i tried to calibrate but it just made it worse.

You need to figure out what's drainng the battery. Get gsam or betterbatterystats to figure out what's causing it. Anything else is just a guess.

If you don't see anything unusual after a few hours of using GSAM/BBS, no extreme wake locks or times held awake, I would then do a factory reset and see if the problem continues, if it does then you may have a bad battery and it will need to be replaced, it is not difficult to do, a simple YouTube search will show you tons of examples of how to do it.
If that isn't it, although it is rare, you would have bad hardware and need to get the device serviced or replaced.

İ was using pa but i unrooted and stocked my devixe yeaterday but its the same.My other battery was way worse but this one is annoying too.Could it be the brand of the battery?

Download and install from the playstore the app Wakelock detector, let your N4 get to 100% in battery and unplug it and try to use it as usual. When it reaches 10 or 5% take a screenshot of wakelock detector and post it here. Try also to take a screenshot of GSAM or Betterbatterystats.

do you try to change kernel or rom ?

Kernels and roms make very little difference. It's how you use the device and the wake locks you get. Without something like gsam or bbs it's only a guess what's causing the issues.

this, absolutely right. battery life depends on how you personally use your phone, how you set it up, what apps you have installed, and mostly on the quality of the phone/data connection that you have.

İ dont think its a software problem guys.My newest stats: http://i.hizliresim.com/rLNLAB.png
Any calibrating suggestions?

We need more detailed information than this to troubleshoot this... Without that information we can't really help. We need screen shots of Wake lock Detector, BBS, or GSAM. GSAM is the easiest to interpret, so shots of the main screen, app sucker set to time held awake, screen and radio would be needed to assist further, in English if possible.

Everything does not look fine...Two things that's bothering me looking at this is the GSAM shot, it is showing you drawing 1500+ma off the battery... Seems very excessive, I usually see 350-900ma at most (433ma at moment). And the 41% of usage by the screen in just over an hour use seems kinda high, what is your screen brightness set at, and what does the GSAM Screen usage screen say, anything in the Medium or higher category is using very significant battery.

"Calibrate" is a misnomer, it will not affect battery life or current draw, years ago in the Froyo/Gingerbread days you would wipe the battery calibration file to reset the display and estimated run-time remaining, it doesn't affect actual battery use or life, just how it is displayed and runtimes are calculated. You can always download a Battery Calibration app from the Play Store and use it, it won't hurt anything but I believe most require root access. I have seen some discussion that this is irrelevant in KitKat since the file is rebuilt on each boot, but I can't verify that.
Honestly though, when I look at your GSAM screen with 2:40 average screen time and just over 3 hours max, this part doesn't look unusual, but it doesn't jive with the screen shot showing 1:19 screen time using 42% of the battery... you are at 12% after 10.5 hours, the phone is obviously sleeping properly (only 28min held awake over 10+ hours is quite good), but at the same time you are showing 5%+ per hour drain. A little puzzling but not outside of the realm of normal.
I'm not really sure what else to say, every phone is different, this may be normal for your device, without screen shots of app sucker and screen usage in GSAM I can't really say anymore... try the standard stuff like switch to Device Only in location services to stop Google Play Services drain, lock the screen brightness at 20-30%, disable syncs, etc.
Of course, this could be something in hardware too... I had a Samsung once that no matter what would drain 5-10% per hour well sleeping even in airplane mode, yet no one else in the forums ever commented that theirs did, turned out it was just a lemon, a replacement would drain less than 1% per hour.
