I have seen pretty many ROMs here, but am unable to make out which ROM is best optimized keeping battery life in mind. Could anyone please help suggest me a ROM or two that give the most of the battery life. Please.
You could take any ROM that will work with a kernel supporting OC/UV (like Setiron's) and use Xan's voltage app to limit the top speed of the CPU to something less than stock (1ghz is stock, your choices would be 800, 400, 200, 100)
Then apply an undervolt as low as you can go while still being stable.
This will of course result in a slower device, but that's the tradeoff. Less speed for more battery life.
Do note that the screen is the largest user of power by far and thus you can make the most difference by keeping the backlight as low as tolerable and shut it off whenever you aren't actively using it.

Thanks Da_G. I did use SetCPU, and set the speed to 800, but for some reason it is giving me lower battery life compared to without SetCPU. So took it out.
Also, I have my screen brightness turned all the way down with auto set to off.
I meant to ask for a ROM that has all the battery hogging stuff in it removed/optimized.
I am currently like 45% left after about 8 hours with moderate usage. Trying to see if I can stretch more than this.
My today's usage statistics:
1. 11 hours 25 min 4 secs since unplugged
2. Battery remaining: 63%
3. Voice calls: 1h 10m 15s
4. Display: 1h 15m 42s
5. 2 gmail accounts with push turned on with about 10 mails delivered today
6. google voice with push all time with about 100-120 messages delivered using push
a. I do not have SetCPU.
b. I have my brightness set to 0, with auto-brightness turned off.
c. I used SamServMode to turn on EDGE, and 3G turned off since the phone was off charging hook. In short, on EDGE all the time.
d. Static but nice, colored wall paper.
Could anyone suggest me if this is good enough. And any ROM that could get me battery atleast on par with what I am getting.
A few of my ideas:
1. Use a dark colored theme. Our nice SUPER AMOLED screens don't use up much power to draw black - so the more black - the merrier.
2. Be careful of what extra apps running. Things like widget locker are one more app to run. Go slender. Theme's are okay if they replace files like frameworkres.apk but if they run in background (see it under processes) then that's bad.
3. Be extra careful of making sure you are fully charged when you flash. This means, charge, turn off, charge, turn on, charge, flash. I get a little more charge when I go back to eclair stock .
also note that 95% of battery is the screen
Everything else that was said before me was spot on so try that too.

OK...so MUCH THANKS to Mr. Carlisle for gettin me all squared away with rooting my Hero and upgrading to Froyo 2.2. All back ups complete, apps downloaded and only major bug thus far is the camera...SO....why is my battery running at 105 degrees on average? What should the normal range be? I turn it on @ 6 am after charging to 100% and wiping battery stats and ten hours later recharge it to 100% (Currently @ 50%) and all day the temp has been between 103 and 105. whycome? HELP!

Because on FRF91 on Cyanogen mod (which i assume you are using) is overclocked to 710 mhz, where the hero's processor runs at 528 normally. My suggestion is to download an app called overclock widget from the market, (Obviously, it's a widget and you'll have to add it to your homescreen) and set the minimum and maximum clock (processor) speed to 240mhz(min) and 518mhz [or 534, if you want to, but it won't make much difference] (max).
You can set the max (or minimum) clock speed to be more or less. Lower clock(processor) speed=More lag but better battery life, and potential to freeze your hero because the processor can't operate the system fast enough. Higher clock(processor) speed= Faster and less lag but less battery life and can damage your touch screen (It's happened to me). if you leave it at too high a clock speed for too long, and can also freeze your phone because your processor can't operate at that speed and crashes your phone.
It's up to you if you want to overclock or not, but you should keep it resonable, and if you have heavy phone usage, don't go much further than 613 mhz for your max. There is also another program called set cpu that is avalible for free for xda members, but is a paid app on the market. Using that, you can set your frequencies to the default hero processor, or of other phones. But overclocking over 710mhz could do some harm to your phone, so be careful.
If you say, "I wonder if this will damage my phone," then don't take the chance without asking around first.
If you have any more questions about overclock, pm me, and I can help you out.
That temperature range, ~40C is completely normal when charging and using at the same time (with me, anyway). I'm OC'ed to 710 and using undervolt, too. The highest I've ever seen mine go is 43C, or about 109F. I don't really know where the "danger zone" is, but if I had to guess it would be around 48C or higher.
Edit: I reread your post, and do you mean it's at 40C always, even when it's sitting doing nothing? If that's the case then follow Ryoma Echizen's advice and fine-tune your CPU speed.
.
..
I use setcpu to do this.
Look into the governors, choose one.
Then choose the appropriate thresholds (in the advanced menu) for what you do.
It doesn't allow you to tweak per app, but tells the cpu governor at what %of cpu to move to the next cpu speed (up or down).
I set mine very low, as i care more about battery than performance. So my up threshold is like 95% or something.
But my down threshold is a lot more agressive.
But you do the opposite.

Hello,
my question is regarding dynamic overclocking. I've used the ones that raise the speed when under a load - but my question is -
Is there a way to return to stock clocks after certain time?
Explanation:
situation1: I want to check new single mail or open new single IM or check university's website for some news, I want the device to be FAST as possible, nevermind the battery.
situation2: I want to use maps/navigation/IM/games/web browsing for longer period of time (hours?) with the screen on. I don't need all the power when I play solitaire, text on IM or browse not-so-important news websites.
I think when I've seen the realtime clock displayed on my phone it jumped to max clock right after I've clicked almost anything on the screen. I want the speed-up, but after certain period of time to stop doing this in favor of the battery life-time.
Any ideas how to do this? Thanks!

Yes, just throttle the cpu to give you more power when you are sluggish. That could work for you.
Me? I have my droid do 110 when screen is off (works quite well!), and then I FORCE the unit to 1000 when plugged in. Besides that i throttle the cpu based on battery power: more cpu power with more battery life. Makes my droid last longer.
I might want to add a throttle up when sluggish and not in my personal battery red zone and a throttle down when the cpu gets too hot period.
Any cpu frequencies that you all would suggest?

MuF123 said:
Thanks for the reply, but - think about this, I will start a 3D game, it will use 100% of the cpu so it would always stay at the highest possible frequency (+highest voltage). I don't want that.

I dont get it?
You dont want max speed in game? Why do you overclock?
If the game requires 100%, the it will (and should) clock up.
As soon as the game doesnt, it will clock down (depends on your threshold).
The only other i could see, is to change the max clock rate in setcpu before you play the game. This will ensure it doesnt clock higher than your choice, but requires a manual step.
But seriously, if your cpu is pegged at 100, why would you not want it to step up the higher speed?

exactly - I don't want minimum battery in game, that's why I don't want to overclock.
actually from the nature of 3d rendering I think every game will run at 100%, but the situation when the game hits the frame limiter (not likely on milestone).
I want snappy performance while doing few quick tasks:
e.g.: new IM comes, I want to unlock, load the application, get to the IM, reply, lock. (40seconds)
or
taking phone from cradle - I want the phone to load homescreen fast, rotate the screen, open phone app, to look at last missed call and call back (20seconds).
Battery life won't be affected by 40 or 20seconds of ~1100mhz, okay.
And then I start a game for a prolonged time. It will run smoothly even on 550MHz, the additional frames I see are just waste of battery = I don't want that.
So now I have two options - either run at max speed and it will be always fast and it will drain my battery when I decide to play for an hour.
OR
I can use default speeds for longer battery life for everything and I will wait an hour to rotate the screen in browser or IM app.

You could compromise and find a max speed that you could undervolt to make it drain battery like stock. My 800mhz vsel is less than the default vsel @550. So the battery drain is less...
It requires some trial and error, but most "slight" overclocks (700,800; depends on the phone) can be configured to drain less than stock.
Of course, if you feel you need 1000 or 1100, this wont work as it requires increasing the vsel (or at least not decreasing it).

Hey guys
Recently just got a optimus black and started playing games more, before i had a HTC dream and Magic was able to get 2 days of battery but atm, I'm getting like 4 hours battery playing **** what are the best settings on nova to get the most battery.
---------- Post added at 11:28 AM ---------- Previous post was at 11:21 AM ----------
+ are there any apps that really help?, using juice defender just with the balanced setting any advanced settings that improve this?
Mainly 2 things consume battery:
a) CPU ~ 15%
b) Screen ~ 80%
For a) you can decrease it by using a good governor for battery, ex: InteractiveX.
For b) it's a matter of having it on the lowest possible brightness you can handle. *
* For example, automatic brightness indoors (low) != minimum brightness, it actually consumes twice the power. Twice.

Thanks for the reply, yeah don't really change brightness so i will do that from now on, also auto uv and underclocking i am going to have a play around with.
Our SoC is already underclocked with SmartReflex.
Further UV won't do much difference.
Oh to easy then.
I bought this phone bcoz of LG advertisment :"NOVA Display automatically adjusts its brightness sensing the amount of light needed, and saves 50% energy under regular settings." (compared to regular LCD). What is the selling point for tat? LG Optimus Black eating battery damn horrible. We like LG Optimus Black including the super-bright NOVA display (LG so proud of it), then why should i need to adjust the bright to lower to save my battery? What's the point???
The point is:
- If you want the brightest screen, and to use a lot the phone with the screen on, it will drain your battery a lot.
Regards.
With CM it's possible to calibrate the auto-brightness values.
I'll try to come up with a good configuration.
So just inherited my dads OG Droid. Currently rooted and runs Steel Droid (Mod Version 9000) and 2.6.32.9_RZ Kernel.
Phone is overclocked to 1GHz (125/1000 ONDEMAND).
Like the title says, the phone gets about 5 hours and then hit's 5% and keeps asking me to charge. If I charge it overnight and unplug it when it's 100%, it'll hit 90% idling (while I sleep) about 3 hours later.
Running Programs:
DSPManager
Words Free
Facebook
3D Digital Weather Cloc
News & Weather
3G Watchdog
Videos
SoundHound
Pandora
Temp+CPU V2
Now out of all the running apps, Pandora, Soundhound, News & Weather, 3G Watchdog, Temp+CPU, 3D Digital Clock are all widgets. Temp+CPU and 3D Digital clock are the only ones that actually run, the rest are just there in case I want to use them.
These stats today are from using Pandora for about an hour over Wifi.
Any ideas? Phone runs fine most of the time but I have seen the occasional lag where you have to click something 10 times before it opens.
I used to have a pretty big problem with battery life too, but even though I think they are somewhat silly and annoying the Easy Battery Saver app helped me quite a bit.
Wifi and using the speakers are heavy on battery life. Not sure how much difference it will make but try consolidating your widgets and app shortcuts to as few screens as possible.
Also your CPU governor might be set to something that lets the phone hog through anything at the sacrifice of battery. When i set my CPU to Performance my phone runs like a boss, while setting it to battery saver I get a little more lag but more battery, obviously. Not sure how/if your ROM will let you change that but it's something to look into.
I got it set to On Demand which might be the issue. The kernel is a low voltage kernel. How do ultra low voltage kernels run?
I did a battery calibration, downloaded Advanced Task Killer (Battery saver didn't work well, I'd always have an issue with 3G not activating) and got rid of all my widgets. Currently charging it up completely, I'll check it out tomorrow.
So the title is incorrect, it says 5 hours and 5% left. I checked the battery info at 5%. It said 4hr 4x min. About 10 minutes later it shut off so I didn't even get 5 hours to a full charge.
I don't have high expectations but coming from an Alias 2 that had the extended battery (I'd get a week of battery with my use), this is pretty disappointing.
Well I can tell you now, ondemand is NOT good for battery, what that governor does is make it so the CPU will go from MIN to MAX speed slots depending on what the phone needs, AFAIK it doesn't scale with need, it just goes to max. So your phones CPU was running at max most the time which kills battery.
Can't say anything about your ROM, but I use simply stunning 5.6 http://www.droidforums.net/forum/chevyno1/177728-ss-5-6-2-3-7-incl-1-battery-other-goodies.html Which, with his low voltage 1ghz kernel set to the smartass governor, I get anywhere from 8-14 hours of battery life depending on use. Using ultra low voltage kernels depend on your phone, some phones have trouble overclocking to 800mhz mid-voltage (mid-voltage is considered to be the most stable, but use the most battery), others can overclock to 1.25ghz ultra-low voltage, which is very rare. I would say try out all the different voltage kernels and see which one works best with your phone.
Also task killer = MAJOR MAJOR No no! The task killer will kill the apps, and the android OS will restart them, using more CPU time and making the battery actually not last as long, I would recommend learning how to use the supercharger script http://forum.xda-developers.com/showthread.php?t=991276
Can't say much about the majority of programs you have running, but I've found facebook does not like to play nice with the Droid, also, why use the 3D clock when the Droid comes with a built in-clock app? Pandora uses a lot of battery, so running it w/ the ondemand governor is probably what hurt your battery there.
Not many Droid users left out there, but I was and still am an extremely avid Droid user, so if you have any more questions just shoot me a PM and I'll help as much as I can.
Thanks! I got rid of all my widgets and installed Chevy's ultra low voltage 1.1GHz kernel on smartass. I lost 20% battery pretty fast but let's see how long it runs. I've had no force close issues so far. I'm a bit tempted to go to 1.2GHz ulv.
How much does the ROM have to do with battery life? I really love this ROM and it's interface. I thought the battery life really only had to do with kernels.
I also got rid of the clock widget and put a default clock widget. What's the built in Android one? Is that the "Analog Clock"?
Sorry for all these questions, I'm pretty new to Android. Only had this for 2 days (~8-10 recharges...)
Its fine, better to question and learn then to just get mad and over it, and Roms have everything to do with battery, they are just like kernels, some work AMAZING on some phones, while others can destroy battery life.
Like my rom, I found the perfect one for my phone, I get 8- (been thinking about it more) 20 hours of battery life on mine and it has pretty amazing performance too with the occasional hiccup.
And I thought you had the clock app installed for an alarm, not for a widget, my bad. I don't use a clock widget so I wouldn't know.. Also, I've found its not very good to run many widgets on the Droid, as it has limited memory and can only handle so much.
Well I got sick of it and reflashed the entire ROM. CPU governer is set to ONDEMAND 125/1000. Only*widgets I have are a simple clock (like the iPhone lock screen) and power control. Gonna see how it goes. So far so good but I'm saying that because I didn't loose 20% overnight. If I can clear the day, I'm good.
googlelover, what CPU Governer did you find to work the best with your phone?
I have been an Android owner for a while now, with the Droid being my first. Until recently battery life had always been an issue for me. Undervolting has never had an effect over a 20% improvement. And this is only when it's in deep sleep. Otherwise, in very general terms, undervolting can require a higher current aka worse battery life if you use your phone a lot. With undervolting comes the risk of data corruption in your phones memory and SD Card. What really kills your phone is screen on time, wakelocks, CPU overclock, and signal quality.
The last you have no control of. But if you're overclocking 1GHz or higher you have to realize that's almost twice the manufactured clock speed. As far as wakelocks, this is when something keeps your phone from going into a low power state. This can happen because of a rogue app, a buggy ROM, or having too many widgets. I ran into a ROM a while ago on my Fascinate that would stay awake if you had GPS enabled. The best you can do with your display power usage is to keep your brightness down. Hope this explains a few things
have the same issue

I already told you, the smartass governor, and like I said before, ondemand is not a good governor in my opinion. There are way to many factors in battery life to have anyone else be able to truly help you with it, all our phones are different and it really just takes time switching kernels, switching ROMs, etc to find what works with your phone
Sorry googlelover, I forgot you already said that.
So update guys. I've been going a day (so like 18 hours) of use after which it finally hits the 15% warning.
What I did:
Basically I reflashed the ROM and started from scratch. Before reflashing, I wiped the user data/cache/davick cache etc at least twice just to make sure it was really wiped.
I reflashed SteelDroid 9.0 with the default chevyno1 lv 1ghz kernel and gave it a go with just a simple clock widget. Worked well. One by one, I'm starting to install applications until I can figure out what was draining the battery fast. So far, so good. If I can get 18 hours on a 2 year old battery, I'm going to be doing fine with my extended battery.
One thing I did notice was that the phone back by the camera (where CPU is) isn't getting as hot as it used to. Makes me think that the phone was at a high clock speed in sleep. Another issue may have been my CPU temp/speed monitor. It was probably poling the CPU stats every second which made the phone increase the CPU speed because it sensed activity.
Try out the ROM I'm using. I absolutely love it. The interface is phenomenal and it runs very well.

Don't forget not many roms have the default android interface, many have themes to completely change the look, if your happy where your phone is, great! But if you ever feel like your phone is slowing down again, I'd still recommend looking around and flashing some different roms.
Thanks, I'll keep that in mind. I'm only using this phone for another couple months. I'll be getting the Droid 4 when it comes out. Looks like a really nice phone.
So as the title says, my note has never lasted a full day on a full charge. Even with moderate use, it lasts maybe 15-16 hours. With heavy use, playing a game or 2 or using the browser, it lasts maybe 9 hours. From the first day I got it I've rooted it and have used only the romow rom.
Currently on the version 7.5 HD.

Each time I flash a new rom I always do a battery calibration test and even wipe the battery stats on recovery.
I notice people get a full day's use from the battery and maybe even more. Is there something I am missing? My wi-fi is always off unless I am at home or when needed. I turn the data connection off too most of the times. When I look at the battery usage in settings (I do this often), the display shows the most usage, always more than 65%, and nothing else. The android system, android OS, cell standby and whatever else are always less than 10%. Is there something I can do to increase the time the battery lasts?

Use black backgrounds and dark apps? Amoleds don't use power to display black. Whites will suck your battery dry.

I would also suggest get your battery checked. But more than likely, Samsung will say 15-16 hours of moderate use is normal.
I am currently using Rocket ROM v20 with Abyss 3.5b. I have had it without charge for 12 hours now and from 100% it is at 82% right now. So far today I have watch an ep of anime (22mins long), gaming for 1.5 hours, had 4 phone calls (total of 42 mins). I think only draining 18% after all of that is impressive.

That is impressive. If I watch a 40 min show only, my battery would go down from 100% to 65. And if I play a game for an hour (depends on the cpu/ram usage the game takes up to), then my battery is at 20%. And this has been since the beginning. The moderate use I am talking about is calls here and there, texting, playing a game for maybe 20 min. Like today I played Shadowgun for a total of an hour, where's my water for 20 min, and texted a bit, made 2 calls, and used dolphin browser for 10 min. It hasnt even been 12 hours and my battery is at 20%. Ahhh I think I just need to get a new battery.
I know roms/kernals/basebands all factor into battery usage as well, so are there any suggestions as to which one might be good with this? Aesthetically I love romow's rom. I love every layout of it. Rocket rom is a little too "in your face" kind of, atleast for me.
Im always set my brightness to 0% and im not using auto brightness. What if you change the kernel to FM 2.0 Kernel. i find it saves more batt than abyss kernel.

That is impressive. If I watch a 40 min show only, my battery would go down from 100% to 65. And if I play a game for an hour (depends on the cpu/ram usage the game takes up to), then my battery is at 20%. And this has been since the beginning. The moderate use I am talking about is calls here and there, texting, playing a game for maybe 20 min. Like today I played Shadowgun for a total of an hour, where's my water for 20 min, and texted a bit, made 2 calls, and used dolphin browser for 10 min. It hasnt even been 12 hours and my battery is at 20%. Ahhh I think I just need to get a new battery.
I know roms/kernals/basebands all factor into battery usage as well, so are there any suggestions as to which one might be good with this? Aesthetically I love romow's rom. I love every layout of it. Rocket rom is a little too "in your face" kind of, atleast for me.

I actually like the "in your face" look, of course that is my preference. I heard that checkrom is good for battery but in all honesty, I have tried a couple of roms and there isn't a huge difference between them. The biggest difference with battery usage I have notice is when you start using a OCing app with profiles like SetCPU. Tweak the power usage with each speed step and create profiles for when the screen is off, on call and etc.

So as the title says, my note has never lasted a full day on a full charge. Even with moderate use, it lasts maybe 15-16 hours. With heavy use, playing a game or 2 or using the browser, it lasts maybe 9 hours. From the first day I got it I've rooted it and have used only the romow rom.

How hot does it get compared to room temp? 15C warmer? 20C warmer?
I'd really love to work with some people to come up with a step by step guide on how to track down and fix battery drain / over heat problems.
The best way to waste power is to make heat with radio chip and GPU. Second best is to make light with torch or screen.
I know with the change in battery technology, some old practice no longer applies but I still follow the old rule of thumb when I get a new equipment.
When I got my Note, the very first thing I did was charge the phone for 12 hours before actually using it. You might want to give that a shot, the reading on the battery may not always be correct.

Currently on the version 7.5 HD.
BB: LA4
Kernal: AbyssNote 3.3
Each time I flash a new rom I always do a battery calibration test and even wipe the battery stats on recovery.
I notice people get a full day's use from the battery and maybe even more. Is there something I am missing? My wi-fi is always off unless I am at home or when needed. I turn the data connection off too most of the times. When I look at the battery usage in settings (I do this often), the display shows the most usage, always more than 65%, and nothing else. The android system, android OS, cell standby and whatever else are always less than 10%. Is there something I can do to increase the time the battery lasts? I'd like to get a full day's worth, and even more

may i know which governor are you using? try to update the AbyssNote kernel to latest v3.5c and try either the AbyssPlug, lulzactive or SmartassV2 governor then see if there's any difference
Running stock LA4 ROM here. Brightness usually on lowest. If you don't touch the phone, it can last on standby a week. See below how it only lost 3% after 17 hours. Of course as the screen was off all the time, the internal processes take most of the power consumed.
After more than 1 day I still have 50% battery. See how it drops fast when I'm using the phone to read and download web pages.
I have the self same issue - battery hardly lasts a day - I just about manage to get home 8 hours later on critical - to hook it up to mains to charge.
All I use it during the course of the day - is browsing forums via tapatalk, viewing the occasional email. No hectic media consumption and music playing.
I am trying a different route now - it was running on stock firmware - over the weekend I've taken the following steps.
Rooted my device , installed CheckRom Revo v5 , running speedmod kernel with modem LA4
Hoping to see how that improves things.

First of all, you should post a screen shot of your battery graph.
How bright is your screen? If it's at 100%, then you're going to chew through battery very fast.
Games that require very high cpu usage will kill the battery.
Some games I can play forever on - some games, like Plants vs zombies, or puzzle quest 2, kill the battery. I can probably get 3-4 hours worth on a battery, and that's with a very low screen brightness. That's the price to pay with a fast cpu.
Dolphin is quite the battery hog too. I try to avoid it - I browse for hours with opera mobile, especially with the green on black mod.

I use the ondemand governor usually with overclocked to 1600. The only profile I have set is the temperature over-heat (temperature above 104 F, 40.3 C) and i've set it to conservative with max cpu to 1200. What should I set the screen off and in call frequency to be? I have just updated to AbyssNote 3.5 and changed the governor to AbyssPlug. Lets see how it pans out tm
My voltage settings are:
1704 MHz - 1375
1664 MHz - 1350
1600 MHz - 1325
1400 MHz - 1300
1200 MHz - 1250
1000 - 1125
800 - 1000
500 - 900
200 - 850
100 - 850

Whats the best app for battery statistics? I will get the graph and post a screenshot tm. My brightness is usually 50 % set in the middle always. Today I put my brightness all the way down to 0, I literally did not use my phone, maybe turned it on couple times during the day for 2 min, sent 1 text, played a game for 5 min, and used a medical application for 10 min, just to check the battery. With that much minimal amount of phone usage, after about 9 hours my battery was at 79%. Is that normal?
Just wanted to say thanks for the help also
it should make a difference. for battery monitoring, I'm using Battery Monitor widget. you may give it a try.

Install better battery stats and check for kernel wakelocks. If there exists some that last longer than 10 mins then some app is involved in the battery leak
