I have the Telus Fascinate which is the same as the Tmobile Vibrant.
I notice that when checking my battery usage that the display is using a whopping 92% of the battery. Is there a fix to reduce it?
I have automatic display unchecked and display brightness to 0.

Nope, but then that doesn't mean the display has used up 98% of the battery the whole time the phone has been on. I could be wrong, but the way I read that info is when the phone is awake, the screen uses the most power in relation to the other listed items. I've noticed on days when I have alot of phone calls, it listed the radio instead of display as the top user.
If you want more detailed usage, I think spare parts shows full battery stats. But I use an app called Battery Left and it has access to the full battery stats.
Thanks!
I will look into both of those apps.

What yatina said. And i recommend using android assistant app in the market if you really want to know what exactly is draining ur battery.

Display using battery is a good thing. Means only drain is from being on rather than the other **** draining it...

Actually it is.
For a average user, meaning not too much phone calls etc. Display WILL always and SHOULD always be the highest.
It just says that theres no other apps acting up.
but it is good to look at MORE detailed stats than the default one though, its not that accurate.
1 hour of display time will use approximately 20% of your battery. This is and always will be the case.

I meant that the stats where it says more than 90% of battery had been drained on display is false. As apps and other daily uses usually contributes about 35-70% of that usage.
Screen brightness doesn't have that HUGE devastation on the battery, when it's in normal percentage ofcourse.
if you're worried about your display draining the battery use the app called screen filter. works like a charm
Also, I'm not sure if this is for rooted phones only, but typing *#*#4636#*#* pulls up usage statistics like battery information and battery history. I think it gives you a better idea of what's going on with your battery.
And can anybody compare it to the Galaxy Nexus, or an iPhone 4/4S (a 4S WITHOUT the battery issue that was going around)?
I'm really interested in switching from 4 to either a 4S or the a Note or Nexus... Battery life is an important thing to me though.
Also, just how much does having blacks on the screen help? How much does that help? If you just wanna answer my first question "How's your battery?" then that's fine. That's what's more important here.
Compared to the iPhone 4, I am getting almost twice the battery run time. I have not changed my habits during my normal day, and use the same apps that are available for both platforms by the same authors. The black home screen does help if you are starring at it all the time, but how often are we doing that?
I am also rooted and using FM kernel. Love the Open Source community.

Some site did a comparison of 3g talk time with a Note and an I****.
The Note got a whopping 14 HOURS of 3g talktime.
The i**** 4s got 8 hours.
So phone vs phone, thr Note wins.

Holy cow! What's your screen-on time? Are you underclocking or anything? I'm guessing your good battery life was because of the kernel?
even @ stock ROM and Kernel, the NOTE is impressive in terms of batt life except if you're browsing a lot (since we all know that AMOLED consumes more juice in showing white shades compared to other display technology) ... Some ROMs and Kernels have battery saving scripts embedded and you can also find a lot of tips on how to improve batt life on our Note...
In my case, my Note can last 22hours+ of moderate to heavy usage; im using Rocket v6 ROM and FM Kernel (undervolted and underclock to 1200mhz)... I set my Wallpapers to the darker ones, customize goSMS with pure black background and themes, disable fast dormancy, turn off GPS and wifi when not in use, use minimal widget as possible, set the brightness to lower level that suit you, set to GSM mode mostly, disable background data when not needed, delete some unimportant processes in the system, manage startup application, disable task manager, and etc...

Yes, the FM kernel did help significantly. The reasoning being that the author disabled the heavy logging Android does for debugging purposes. Other than that, everything in the kernel is stock. No undervolting or underclocking. I also keep away from any app that overclocks the CPU, they usually mess with the phones ability to go into deep sleep.
Screen on time: 4:29m
regarding deepsleep and unwanted processes in background; you can install CpuSpy, Watchdog or Wakeclock monitor app if you're having an abnormal battery drain...

CPUSpy is a wonderful lil app. That is how I determined that SetCPU broke the phones ability to go into deep sleep, even after uninstalling it. I had to flash the ROM all over again.
Compared to iphone 4 gnote battery is less... the reason is bigger battery.
However even with heavy usage my battery last till night every day.
battery life has got better with time.

true... the apps i posted are all essential IMO... wakeclock monitoring is also very helpful in finding faulty apps running...
I'm getting glorious battery compared to my GSII.
Granted it's relatively light usage for now because of work and such, but I'm impressed. Almost always have the brightness at 25%, never need any more.
The sudden drop was from a restart.
My battery life was fine until Google started selling apps for 10p, I downloaded Jelly Defence and I became addicted to playing it...

its good practice to save battery to turn refresh interval for apps that access the web for updates such as social media, new readers, etc to manual to help save battery life as most of these apps refresh on a pretty regular interval and defiantly eat up alot of battery
If you notice especially high battery drain and recently used your GPS or Camera they can occasionally stay on with no visible signs. Also please remember the battery stats is HIGHLY inaccurate. A Phone reboot usually fixes this.
Never keep apps like Skype, IRC, etc that stay running and keep your CPU on they drain battery especially fast!
One big battery saver is to not wake your phone to just check the time. Let the CPU stay in deep-sleep as long as possible to preserve power until you actually need your phone for something.
One MAJOR thing to save power is DO NOT MESS WITH CPU SETTINGS!
Do not use 3rd party apps like Voltage Control or SetCPU or even the built in Performance settings as modifying the settings will increase the minimum clock to 200MHz which will greatly reduce battery life than NOT messing with them. This is a known issue and will be addressed in a future release!

If you DO decide to run a custom kernel, (NOT, I repeat NOT recommended or supported by CM9 devs) I'd suggest Control Freak. I ended up with a 200mhz min, and with that app managed to get deep sleep and 100mhz back. WITH uv and some minor oc. My battery life is great.
Head on over to the app thread here: http://forum.xda-developers.com/showthread.php?t=1072403
Another thing that can save battery, Screen Filter from the Market (Play Store now I guess) can dim our screens lower than the lowest stock increment. Useful for dark environments. (Movies, night outside etc.)
This should be obvious, and has been stated already, but it bears repeating: TURN OFF DATA AND ALL OTHER MODEMS if you're not using them.
Thanks to all the devs and everyone who contributes.
YES!!! It seems a little bit more snappy or is it just me?
And thanks for the advice not to run custom kernels...
Without a doubt, the biggest battery saver for me, is to turn off data until I want to use it.
I simply cannot believe the difference. Makes me think I'm gonna have to go out and get Juice Defender, and let it turn off data when I put the phone to sleep, it is just that dramatic.
I can call text, and play hours of games, and still have the battery have more juice remaining than it did over the same timeframe with just a call or two for usage with the data on.

Rather than installing an additional app to control brightness, why not just tweak the settings yourself?
System Settings / Display / Automatic Backlight
Check "Use custom" and set a lower Screen dim level. Use "Edit other levels..." to adjust the steps for auto brightness if you use that feature.
This is a fantastic feature if you use the phone in low light conditions.

This first and foremost for me.
I took my phone to a basketball game the other night and turned data off. From when I left work to when I got home was about 7 hours, and I didn't plug in for another few hours later and still had some juice. Compare this to last night when I went to class and had my phone in my pocket with 4g on for a few hours, I arrived home and my phone died 15 minutes later. Total time elapsed, 3 hours 46 minutes.
Particularly 4G data is offensive in it's battery consumption.
I have also found that putting the display on Auto Brightness saps my battery. I just adjust it whenever I need to, keeping it on the lowest setting most of the day since I'm inside a lot.
The mmc_delayed_work and deleted_wake_locks are driving me crazy. I know they've been reported as "false blames," but something, whether MMC or otherwise, definitely causes seemingly unnecessary wake locks, and there is a very clear pattern between high report percentage and battery drain.
I don't mean to take away from the optimizations suggested; they're definitely useful if you're looking to stretch the battery life out longer than typical stock capability. But for many of us, something wakes the phone a little too often, and it's very difficult to debug without disabling every single application and testing one at a time.
I guess the point is, has anyone else found a better way to figure out these wake locks?
Why is awake time in Android OS always more than double the display on time? That sounds like serious wake locks. What can I do to reduce that?

Don't overlook the AudioOut_1 wakelock. Its my number one offender at the moment.
Minimize it by turning off screen selection sounds... System Settings / Sound / Touch sounds.
We need to figure out what the problem is with that.
On the good side, my mmc and deleted wake locks are negligible so far on beta.

If I might be so bold to suggest, put a section on your page for "If you get worse battery life on this rom than your last rom, it may not be because of a problem with this rom, it may just be that way and there may be nothing that can be done about it because that's just the way it is."

Just spend a day with CM9 Beta 0. It's a great rom with lots of promise. Great feel and look, very fast, ICS is fantastic.
That said, the battery life is not there yet. I basically set it up the same way I set up the stock rom. Email on Exchange push notification, EVERYTHING ELSE on manual sync. On a stock rom I usually am at about 40% after 12 hours of moderate use. About 5% drop an hour. On this rom I was at 75% after 2 hours. About 12% an hour. This is with the "stock" 1800 mAh battery.
If the devs can match the battery life of stock GB I'll be back. It really is a great rom, I just can't recharge twice a day, and I'm not carrying around a 3500mAh battery in my pocket either.
Seriously, great work to all the devs who have taken it this far. Looking forward to the next couple releases.

I use JD for this and run it in extreme mode, which disables data until you physically enable it yourself (and after you enable it, it will disable again when the screen is off). Using it, I get a huge improvement in battery life, especially on CM9. It's kind of annoying having to enable it everytime you turn the screen back on, especially since it takes 4-5 seconds before data works again, but if it can give me the type of battery life it does, I am all for it. Other than the slightly noticeable lag I get compared to CM7 and other ROMs such as CleanGB (I know I can install supercharger, but I am talking pure stock CM9 here), I have no problems at all. Major props to all the developers involved for breathing new life into our OG Epics.
Hello i had this battery drain problem the battery was draining so bad.İn seconds it was dropping from %49 to %46
So i changed my battery to a mobile technicer.But same problem is keep happening, he told me i should charge my phone for 10 hours on my first charge and i did it but its all same.
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.

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.

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.
Since a few weeks I'm experiencing excessive battery drain on my stock Android Nexus 4.
What I tried without succes:
Switching from Chrome to Dolphin Browser
Lowering screen brightness
Lowering screen timeout
In the attachment you can find screenshots from monitoring app GSAM after half a day usage.
Mainly did some browsing, partly on 3G.
How to find out if the culprit is some background process, some app or some Android 4.4.* update?
First, you need an add blocker. If you're rooted try adaway. Google it.
I don't see anything terrible there. You're signals look good. But they're usually the main problem. If you had low Wi-Fi or data signals they could have caused your issue. The browser looks a little high relative to your screen on so maybe that's a little bit of an issue. Is this a one time occurrence or is it typical?

Thanks for the tip.
I've been using home WiFi and the best 3G provider of my country, so in theory the signal should be healthy.
The day before yesterday the phone shut down after 8-9 hours being on, of which 3 - 3,5 hours active usage.
While browsing I see the battery dropping about 1% per minute. This is since about 2 weeks (not sure whether it's since a certain Android update).
I've read some user complaints about battery usage with the recent Android updates, but not about solutions.
I'll attach new screenshots from GSAM later today when the battery is almost empty.
