Best Battery Settings NOVA - LG Optimus Black

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.

[Q] battery optimized ROM

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.

[Q] dynamic overclocking

.
..
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.
MuF123 said:
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?

MuF123 said:
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).

how much does the governerr really effect the battary?

im just wondering how much does the governerr effect battary life? i changed from ondemand to smartass2 and im not sure i see any diffrent...
and im scheduales which one is best for multitasking and which is for when playing games?
and should i change the governerr setting?
i also read that sleep_ideal_frequency should be 200 and not 100 beacuse 100 wastes more or something like that, is that true?

I use Performance governor all the time for 3 months now, battery life is same as on demand, smartass v2 or any other governor, except my phone lags much rarely than on any other govenor. For those that dont know, CPU of PC, your phone, calculator or anything else always works at 100% of its frequency even it has no work to do (Let's take for example your PC, even cpu usage is 5%, CPU still works at full frequency, the same works for your phone), so to me there is no point of any other governor except for Performance. If you have problem with battery life, it's mostly your screen. When I drain out my battery, my battery mostly get drained by screen (70-90%), I use about 0-30% of brightness always. Screen of 60-100% brightness will probably drain your phone's battery in 2-3 hours.

This is so wrong its a pain to read.:banghead: Why do we have the max and min frequency options in the semaphore app? Why do we have "Max Performance" and "Max Battery" power settings on laptops?

There was a thread some while ago that concluded in OnDemand and Performance being to two to give longest battery life and best performance.
I don't have specifics or even a link, but the thread was about schedulers and governors and which went together for best performance and battery life. I'm sure it's google'able

i found that thread but im just wondering how much battary life is wasted if i prefer preformence?
lets say i use smarassv2 since its faster will my phone drain lets say insted 20%\hour - 22%\hour? or is it more then that?

maybe you can try and tell us
There should be a significant impact regarding battery life when using Performance for example. But it also depends on what you are used to. If you play games all the time or do heavy tasks, the governor will kick the CPU to 100% all the time anyway. But if you mostly surf on the Internet or read texts there's no need to let the CPU go rampage.
Oh and Btw: Modern CPUs in notebooks or computers in general clock themselves down as well when they're idle.

[Q] Which Governor/s to deal with heat

Hello,
A friend of mine is using the phone for facebook/whatsapp only and he really hates the heat from the phone
I guess those apps don't need the CPU to be at max freq so my question is:
Which Governor / Cpuquiet Governor to provide the least heat and an a reasonable performance for those apps?
Interactive or ondemand governor and lowering max frequency to 860 MHz should extend battery life and reduce heating while keeping the phone running smooth in those apps. For gaming turn back to original frequency.
Alternatively, min frequency to 860 MHz and powersave governor, but the first option is better, I think.
Thanks for your reply I set the max CPU to 910 but I don't know what to use out of the three governors:"abssplug , interactive , ondemand"
I set the max CPU to 910 but I don't know what to use from those three governors: "abyssplug, interactive, ondemand"
I don't know the first. Interactive and ondemand are working similarly - they reduce frequency when max isn't needed, to extend battery. I recommend you to use one of them.
Hi Community
I have installed last stable (3.1 from 3.07.2014) version of LiquidSmooth and Mourty's kernel 3.1.10. I would be extremely happy, because I have never seen this phone working so smooth and fast, however I have two major problems:
- can't change preferred network option, there is only 3G to choose, I actually need 2G. May that be operator's (O2 in UK) fault?
- second problem is even bigger. It takes 9 hours to discharge 100% battery to 0 when I'm not using the phone at all (0 calls, 0 texts, 0 wifi, no gps... just laying on the table with everything switched off). On the CM or stock ROM I had completely normal battery life.
My settings:
CPU speed: 51000 - 1150000
Governor abyssplug
Cpuquiet Governor balanced

Please I really need your help as at the moment phone disconnected from the charger becomes useless...
Ondemand- when in idle the phone is on the lowest frequency. When in use, it is at the max frequency.
Interactive- is a scaling governor that scales the CPU frequency based on the load. Its possible that this will allow the CPU to stay at lower frequency with screen on thereby saving a little battery.
Abyssplug- is a hotplugging governor that scales the CPU frequency AND number of cores active based on the load.
I suggest using abyssplug with the "balanced" CPU_Quiet governor (CPU_Quiet determines how many cores are active at any given time) to save battery.
To reduce heat, you can underclock your CPU to 1.3ghz and undervolt your CPU based on your CPU variant. Also I've noticed that replacing the crappy lg battery also reduced heat since the lg battery is covered in plastic and does not dissipate heat very well
Also what kernel are you on?

Thanks for answers mates. Right now battery draining when phone should be in deep sleep is 10% per hour. over 70% of that is used by kernel, however I have reinstalled kernel yesterday and it didn't help at all. The strange thing is that when the phone is switch to plane mode it doesn't drain energy at all, 1% per few hours. I would understand that if the draining would be described as searching for GSM singal, but it's not, that's another 28% of battery usage. So there is definitely something wrong with gsm signal.

I have also that phone and i am not happy. Why is very hot. And also the battery is crap. Is logic for battery do not take long time, because the heat it means energy . Its caloric energy you lose. I want to try to lower the frecvency of cpu to 1000 . But ... Its like i have an MERCEDES car and the engine is not good( low power and higher consumption on 100 km). I am not recomand that phone. The chinesse phone for ex with mtk cpu is more good. It is a fix for this? I see here in the forum a guy who put siliconic vasseline on cpu. Maybe a cooler , like on the pc . Shame of you lg. My friend have the same phone and like mine have the same problem with heat and also the left corner of display is unglue i think because of heat. If you put the phone in light and look not straight , in upper corner its like on samsung s3 phones for ex , when the special gel between display and touch is damage. You have a problem like this with the display?

That's what I felt about it before I undervolted CPU by -135 mV and LP cores by -75 mV, underclocked to 1300 mhz.
The technology this chipset uses is the problem here.LG did a fine job with keeping phone cool in stock kernel, though stock performance is not compareable with custom ROM/kernels as customized ones have better performance.1300 mhz is fine though, unless you play heavy games such as real racing 3 with many bots around, you won't feel the difference between 1300 mhz and 1500 mhz.
re
I see what is the problem with my phone with temperature. First i want to tell you about someone on forum who open the phone and see how the producer (LG) make the cooling. On the motherboard in the cpu zone it is a metalic sponge who make the transfer of the temperature with the metalic plate inside the phone. It is the same plate you see on the back when you take the battery. So, in his case and mine the problem is this sponge dont make very good connections with the metallic plate. WHy? Because ( in my case) , the lcd in the top is not glue very good, the tape double adesive is open. I think in time because of heating , the tape is opened. What do you must to do? If you can not make , put someone who repair the phone .So, you must to put some termal paste like pc cpu , or put a small aluminium plate, between cpu and the big plate inside the phone. That it. Ony if you have problem with the temperature like me. For ex . yesterday , without termal paste my cputemp it was max 60 degrese. Now , after modification i have i game and cpu stress app max 39 degrese. I am very happy now, but i must to rezolve also the problem with the bettery drainage. Maibe i must to change the battery. If you want to speak and put answers you found me on facebook cgamberea , or [email protected]. Sorry for my english, i am from Romania.

[Q] CPU running at high clock most of the time

Updated section:
After clearing cache through recovery and doing a hard reset, the uAh has gone back to 3142000. Standby time seems good with the battery losing 7% overnight. It does charge quite quickly from 0-100 in about 2h. The previous heating issue remains with cpu monitors showing that the cpu jumps to high clock when I touch the screen. I don't see any change in which apps use the most battery with the screen taking up the most as before the problem started.
The heat appears to be what is draining the battery but I can't find any single app that causes it to ramp to max.
Pictures:
No-frills is set to stock settings to see how the phone handles the actions
2nd picture is when phone is idle
3rd picture is immediately after swiping through a few tabs and scrolling through some pages in the app which causes cpu clock and load to increase
Old sectionFor when battery uAh was low)
I've had this Z1 for about 11 months. I can only get around 2.5h on screen time with regular usage. The battery uAh was only 1848000 Recently it fell to the 1700s. Calibration appears to reduce the value further. The phone seems to heat up in about a minute or two no matter what app is running.
The phone is rooted on stock 4.4.2
I have tried updating to Lollipop before but received an error due to rooting, so I don't think anything changed.

sounds like it's time for you to replace your battery.
You may try to disable the "input boost frequency"
By default when you toch the screen, cpu frequency of two cores instantly jumps to around 1400 to preventing any lag but it seems to use more power and causing heat
I have disables this and since then I'm no longer have any heat issue and also the battery life is so much better now but you may exprience a little lag while scrolling on heavy web pages but thats all
Btw i'm on .157 and using Kernel Adiutor for cpu tweaks
You may disable this by the app mentioned above or by editing sys.somc.touch_perf_kick=1 from 1 to 0 in buid.prop or adding this line
