Hi Guys,
Since I have BroodRomRC2 with Cranium v6 Kernel my battery stats are weird. It sais my display is using a lot of battery, but I have set the lowest brightness there is. I already tried to fix it by resetting Battery Stats in Recovery... What can I do?

It's normal having display usage around 50%, the only way to make it last longer is displaying dark images, since super amoled screens waste more battery with bright images than dark ones, 'cause we have not retroillumination but each pixel is emitting his own light. Dark/Black backgrounds, dark themed apps etc improve battery time.
Mine with heavy use is around 40%. Dark background, black themed GOsms, black gReader, and so on..
BTW, wrong section
One thing i have realised since i have switched off automatic brightness and set screen to lowest brightness. Androids own browser is using more brightness than other programs. That is one of the reasons i have started to use other browsers.

Press the menu u'll see brightness setting. Change it. The default browser is the best
If your screen is the biggest consumer of energy it means you have a very batterysaving rom be happy with it !
Anybody else got battery drain while listening to music? (mediaserver drains about 40% when only music is on)

Display Brightness problem with my Galaxy S
Hi I have bit of a problem with my galaxy S' display. The display uses a ton of power (90% +, going down 1% every 2-3 minutes with display on) as per the OS usage data. I have not experienced brightness settings / power saving mode as having any effect in terms of extending my battery life.
Now here's why I think there might be something wrong with my phone. I know two other people that also have a Galaxy S. We come together often last time I noticed their displays are MUCH MUCH brighter. I took all three phones on the table and noticed that regardless of the brightness level I set on all three phones, whether it be the minimum brightness setting or full brightness (all 3 phones SAME settings of course) mine is always the darkest. Also their phones display 40-60 % from the total power used by their display's rather than mine always showing 90%+.
I tried a battery recalibration etc this doesn't do anything in my view. After trying some great suggestion on this forum, I alway set the display to its lowest brightness setting, still no difference.
One of those other phones is running the same S/W as mine (doc's rom JPA) the other is still on JM2, so I can definitely exclude the firmware version as a cause.
Any thoughts suggestions as to how to solve this? Or might I just as well stop bother with that and have Samsung exchange the phone's display?
I have the same problem.. Did you find a solution?

Hi, No unfortunately I didn't. It is kinda strange I'm not getting any response on this thread. If you and I are having the same issue, I find it hard to believe we'd be the only ones!
There is a "smart management" option under settings (saves battery). This seems to change contrast etc when enabled and makes screen dimmer. I have to SGSs and I can confirm that, Check it and tell me whether it worked.
nb: this option will make a full white screen dimmer than if you have half white and half black (the white will be brighter in the second case - probably to improve contrast).
Hmm.. this is what I did.. I placed the brightness slider to the left and switched on the automatic brightness control. Now battery use does not show 50% or more in average use, but seems normal, like it was before froyo
Smart Management is off
First - let me state - and it is true - that I used the search function.
I read pages and pages of advices to lower battery consumption on my HD2 Android... without success...
First I used an SD ROM. I read that a NAND would improve battery life. So this is what I did.
I am also using SetCPU with a profile when battery <30% and another one when screen is off to LOWER the CPU speed. In normal use, I set CPU speed at 768MHz trying to lower power consumption...
I use a task killer to free memory and prevent silly programs to drain my battery off...
I use Juice Defender to control wifi, data, etc...
And with all of this in place, my "Current widget" shows a consumption of 180mA with screen on doing nothing, up to 350-400-500!!! mA when acutally using the phone wifi+sync...
In the forum I read consumption like 3 mA - 9 mA!!! This is FAAAAAR Way lower than what I ever had with different builds...
So this is an help scream to everybody: what is your battery drain, and why mine is sooo High???
Hint: I am also a fan of LCD Density changer, with setting at 165... can this have an influence on battery drain??? I reverted to the original 240, doesn't seem to have any influence...
Thanks for your help,

My drain is 3-9 ma in STANDBY ONLY now and again slightly more but mainly the values stated. And my screen on between 120+160ma. Turn off auto brightness if you have it on, and set it at the lowest your comfortable with (display is big batt drainer) I DONT use taskillers as they do more harm than good. I use NO undervolting and only the default settings with my rom. I have low lcd density setting 167 i think. Lcd density has no effect on your battery drain!
Found this here. http://forum.xda-developers.com/showpost.php?p=13151738&postcount=11296 Might be of some use to you? (from hyperdroid gbx thread)
Whats youre rom?
And do u use ext partition on sd?
I dont even use SetCpu anymore. Only taskkiller.
Auto-brightness is on
Auto sync is off.
Im using UD 3.3 nand from crawlingcity
Stansby is 3 -6 ma
Using round 160 to 250.

How long does your battery last from 100% to self shut down? As for Current Widget, keep in mind that when people say "Standby", its generally referring to the screen being off. Set current widget to update every 30 seconds, and turn the screen of for 40 seconds. Then quickly turn the screen on, unlock, and check what it is reading then.
If its still high, try "Force Stop" applications in the Settings > Applications menu one by one, i've had to do this more than once to locate problem apps that were destroying my battery in standby mode.
I'm knew to Android, let me share you my idea.
I use UD3.3
I removed google stuff
gmail, search, etc
No auto sync
Location off
Always kill market when screen off.
I use beautiful widget for weather manual refresh.
I use battery widget
Auto level for screen
sometimes WIFI on
2g Only
2 or 3 calls,total of 3 to 4 min a day
My battery stay 48 hrs in STBY mode.
I think the most draining factor is
1) google stuff they are battery hog.
2) screen
3) bad written programs (every time they check connection to
internet or looping for doing something, looping will make
CPU in high frequency).
4) bad device driver such as BT which is known as 60ma
drain. it is not the hardware but it is the software doing
the drain.
thanks

The attached images should speak for themselves. My brightness settings are at their lowest, at least the one I could find is. But still the consumption is around 80%. I lost half of my battery in three hours.
This problem started after I flashed to http://forum.xda-developers.com/showthread.php?t=1757272
I fear there is some hidden setting or something to fix this, as the screen should be a bit darker, but i have failed to find anything useful.
Edit: Got an app called "RootDim" and used it to set brightness to 1 but the screen still remains way too bright.
hey guys,
i tried today mirroring my navigation app to the EPD screen.
in my mind, it should save some battery, but actually checking the battery percentage, I didn't notice any improvement over just using the main screen.
what do you think guys? does it really save battery?
THX
Using the epd saves battery only if it doesn't need to be updated. If the screen is redrawn all the time then the savings are minimal if not nonexistent. Personally I habe disabled all the animations from developer settings, but mainly it depends on the app how efficient it is.
You might also want to look at this: http://m2appmonitor.com/google-maps...e-2-most-popular-android-gps-navigation-apps/
I suspect that the screen is actually not the most draining thing in the app. .. I found that with Waze my old Samsung phone would barely be able to charge even when plugged in and running the app... and you don't need that sort of power when looking at the screen!
I am using a note 4 910c
It has screen burn-in and the keyboard and messaging app image constantly shows in the background most prominently when against whitish background.
I have used softwares which claim to remove these by running green blue red n white screens in full brightness for atleast 20 hours in 2 to 3 days but No improvement whatsoever .
Any other solution? or if i might wanna use these softwares more ?
You could try using negative colours, under accessibility menu. You will need to replicate the burnt image.
No guarantees it will work 100%, but anything with excessive sot is guaranteed to be detrimental to the display regardless.
Try installing and running the Screen Burn-In Tool for a couple of hours on your device. It might help.
