Backlight settings for optimal battery life?

hey guys! which backlight settings do you use for optimal battery life? 40% brightness? or do you just use the automatic version?

I use 50% when watching films, 30% general use and 20% to 10% around the house in the evening! Bright screen on this beast - no need to use the auto settings as this seems to give me the equivalent of 20-30% "overbrightness".
I use a program called "Backlight control" by Ulrik Jensen, and I have it as a short cut on the today screen to quickly alter the settings...

[Q] Help, what is your battery drain, and why mine is sooo High???

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

Battery Life?

How long does a full charge last for you on your continuum?
I got a new warranty replacement battery from verizon yesterday, because my battery only lasted 4 hours. This was with turning off applications and having the screen off. I also have the brightness turned all the way down for when I actually use the phone.
Right now, Im running Adrynalyne's kernel and the "3.30.11 Clean Continuum DL17 Rom". I hope this battery lasts.

Mine will usually last all day (around 12 ish hours) with moderate use (meaning checking facebook, browsing the internet lightly and checking email, making calls and texting). I've never had a problem with my battery except when I first go tit and I couldn't put the thing down lol

Tricks to get your battery to last longer:
1. Get "Advanced Task Killer" from the market and kill all unnecessary processes that run. The Task Manager that comes on your phone can detect applications that are multitasking, but it can't detect processes. Processes can randomly start running when you open apps like Facebook, Browser, etc. When you press the "back" button to exit an application, these processes keep running and consume lots of battery life. I saved muchos battery life with this app.
2. Go to Settings>About phone>Battery use and see what's consuming the most of your battery life. Click on the items you see that are consuming battery life and it'll tell you if you can do anything about it.
3. Live Wallpapers consume a considerate amount of battery life, so if you're having battery problems, avoid using them.
4. Remove unneeded widgets.
5. A friend told me using battery conserving apps actually increased his battery consumption. I don't know if it's true, or why that would be but I would try testing to see if using a battery conserving app actually helps, or makes it worse.
6. Turn off WiFi when you're not using it, or it will constantly attempt to search for WiFi, decreasing your battery life.
7. Try using SetCPU, and set a limit to the processing power (is that what it's called?) that your phone can use. Don't set it to the minimum because you don't want a laggy phone, but try lowering it a bit and see if that reduces the amount of battery life used.
If that doesn't work, nothing will. I don't know why you only have 4 hours of battery life, but that should fix anything that makes your phone have less battery life

There's a better apparently than adv task killer it has like 5 apps in one its called android assistance. And its worth looking at trust me

[Q] How much battery life are u getting??

Hi,
I am using quantum with mango update and i am getting only 6-7 hrs of battery life tops. So i just wanted to know if this is the case with all or only for me. I use 3g network and browse for 1 hr or so.

Battery life varies on how much talking you do, so to conserve battery, you need to turn off data, wifi, gps, and Bluetooth and turn them on only when you need them. I have to charge my phone every night. So your battery life is consistent.

Using 3G for continuous use, really drains your battery, so it's normal to last so few.
You could use some tips from Rob Miles: robmiles.com/journal/2012/3/4/lumia-800-battery-life-tips.html (even though they are for Lumia 800 they apply to all WP7 devices)
Also, you could track to see how many apps are running as background tasks (settings-> flick left on the applications pivot item, and select background tasks).
But the general advise is to carry an USB cable and hook the phone into a computer everytime you can, to maintain it consistently charged.

[Q] How to get better battery life?

Hi everyone, I'm currently on CloudyG3 and i wanted to know how to get better battery life. I'm using Eco mode, Greenify, 2x Battery utility and still im getting only 4h SOT. I've seen people on older versions with 7h SOT. Does anybody knows how can i maximize my battery life? Thanks in advance

Turn off google now, syncs, and uninstall facebook. That's what did the trick for me. Also, location settings to off.

Google search (velvet.apk) always eats my battery. So i always delete.

Start with wakelocks and everything automated like syncing and such... After that make sure nothing is getting in the way of screen off battery consumption... From there Basically ur looking for longer screen on times which really has to do with your type of usage... (I can play games while listening to music and get a max screen on time of 2hours or I can read forums check mail..( do stuff that's not cpu/gpu intensive) and hit 6~7 hours screen on time)) Remember those high screen on times are for test purpose and not daily use (unless u really hardly use ur smartphone as 1 )...
Step1. Turn screen brightness to sub 0 value using something like lux auto brightness.. Screen brightness is ur 1st enemy.. control the minimum comfortable brightness u need and that alone will give u an hour or so extra of screen on time... Next is apps running and cpu freq (control what's running and how long u stay on high freqs~ the longer u stay there the more battery u use up..)
... Clear memory when uve used many apps during the day( some tend to stick around when not needed and use battery~ make sure greenify does its job)
Find a good profile for usage between freqs~cores online~ this will introduce lag but nothing too crazy if ur willing to squeeze every last drop of juice
