[Q] How to set the frequency for battery,with stock kernel? - Optimus One, P500, V Q&A, Help & Troubleshooting

I have only flashed the rom not kernel in LG P500.But want to see if the frequency of the processor can help me.My battery drains very fast and i don't play any games etc also.
My minimum is 320 Mhz & maximum is 600 Mhz.I want to do mainly coz battery is draining too fast & not once i am able to charge full.Thanks

Hmmm you may have to calibrate your battery
Use this app
https://play.google.com/store/apps/details?id=com.nema.batterycalibration
BTW which ROM are you using ?

all CM based roms shoud have in settings development a thing to activate to show you CPU usage, if you tick that option, CPU usage(frequency) it will be shown on home screen in a little widget
or use CPUSpy
if battery drains fast it is because of various problems, wifi, apps that runs in background and prevent deepsleep and causes wakelocks, but CPUSpy it will list all hungry apps and all CPU usage
cpu frequency cannot be set over 600 with stock kernel, but it can be changed with some apps like SetCPU or CPUMaster (root required), this apps have profiles for different situations (screen off, charging, gaming, music, talking, net surfing etc), if I remember SetCPU can be found here on XDA free, search it

Thanks, but in this rom there is one feature called 'performance control' and it shows exactly what cpu spy shows.I have used cpu spy and it does not show hungry apps,maybe it is cpu spy plus.
I AM CHECKING REGULARLY AND MY PHONE IS NOT GOING INTO DEEP SLEEP AT ALL EVEN WHEN SCREEN OFF.
And i have installed only whatsapp and titanium.My battery was at 80% when it freezed and when i took the battery out and restarted it battery was at 40%.
And i am concerned about the minimum frequency which is 320 in this,it can be changed to 122 which is not being used coz of the default settings.I s it safe to do?

with stock kernel any freqv is stable, but it will not help, something is preventing deepsleep, uninstall some apps that you suspect that can do this problem, search web abouth apps that you have installed on your phone, or read pacman thread or change kernel, I do not think a custom rom runs well with LG stock kernel, and when you flash a custom rom that rom comes with a custom kernel, try DJNOxD or sweetnsour 2.6 kernels
change governor and test it, maybe it will help, I allways use smartass governor but search forum for governors preventing deepsleep

I think my phone is not going into deep sleep and it is coz of the minimum frequency which is 320.
But still i will try battery calibration but i can't install from google store.Is there anyother place or can you attach here the apk?

Yeah i have already installed betterbattery stats,lets see.Don't if i will be able to understand what it shows,set it to partial wakelock though.Pac Rom thread is not responding since three days,i mean no reply no help as yet.
Tomorrow i will do to things,one is remove this rom and have another & second is to remove the gapps as well and reflash.I do not know how to this.Then i will know if rom was responsible for this or not and decide for the kernel therafter.
Should i make new thread for that or you will tell here only?

or you can change rom if you do not solve the problem

oh, sry, I'am a big NOOB, all JB 4.2.2 are using 3.0.8 kernels that have big problems with wifi battery drain, it is a common problem with all JB roms, disable wifi And drain should be ok, but I recomand to use an ICS rom that uses 2.6 kernels
but this problem is known by everybody and discussed to all JB roms threads and in link that I provided you, so, it cannot be done by me or you, we have to wait for the people that can do real things in here, developers
this problem is because Qualcom and Google does not support old ARMv6 processors in JB, so with all the magic from XDA developers some problems cannot be solved

I do not use wi fi,i use only 3g.Mine kernel version it says is 2.6.35.10.
I used BB stats but did not understand much,only thing i could understand was gps location provider running all the time.
Phone did not sleep for one second neither this 'gps location provider'
By the way which cpu spy or cpu spy plus you were talking about which tells about the apps consuming battery,coz even in the cpu spy plus it is the same like cpu spy.

I was mistaken, it is better battery stats

[Q] Which is the best firmware for S5670

Dear Friends,
For those who love visiting the Development section of this forum, you would notice that there are many firmwares available. Also these firmwares have corresponding Custom Roms made by our great developers.
Therefore i would like to ask, which is the most fast, stable and battery effecient firmware for our phone ...
In other words , which firmware, truely Fits the Fit ????

Well,,,,i feel that the de-odexed KPL (2.3.4) firmware with FITDroidv2.0 custom Rom ......both of them are by VISHWANATH PATIL!...i am using it and its supercool,fast,energy efficient and super stable!
if you want official firmware go for Gingerbread DDKQ5
and
if you want custom firmware go for Fitdroid it is very fast than official firmware. and it supports darktremor app2sd which completly moves all apps to SD
and saves a lot of internal memory space;-)
Thanks Vaibhav,
Have seen the post of the entire rom containing darktremor app2sd bundled with the Custom Rom. Could u pls tell me if we move the apps that are actually meant to be on the phone memory, will it affect their working or performance??
KK
I flashed the deodexed XXKPL firmware, FitDroid, Blue Steel theme in the same order.............I must say it is working perfectly and just one bug I feel is that the music player force closes when opened

If you want to save some battery life
try using JuicedDefender it saves a little bit of battery
or use SETCPU and select profile which is best for you
Pratyush creed's rom v1.0
I tested all most all the roms and i found creed's rom v 1.0 is the best for me.
Ram utilization is very low when phone is idle and so the battery performance is better.

No there not many bugs in cyanogenmod 7.1.0
the only bugs that i hate its
1.FM does not work even if e use spirit fm app
2.USB tethering does not works
But it can be fixed using weird tether app
And the 801 mhz kernel its little unstable
I faced random reboot issues
So I'm using 763 mhz kernel its stable
And it don't have any issues

sorry for having too many questions...
According to my test spirit fm radio doesnot work so tgere is no alternative of it till now
Secondly battery consumption depend on how much do you overclock your processor for eg 700mhz will consume less battery then 800 mhz overclck produces more heat and strain on processor so it can damage your processor over overclock your procesor than stable overclocking

hmm....dont have an alternative for fm...but as far as oc is concerned i too want it to be ported to FitDroid..and dont worry its in progress!...and we'll get it soon....battery backup will definitely be an issue ...i use overclock only while playing games..and i get a nice battery backup!
galaxy fit + CM7.1 (2.3.7) + 801Mhz
I definitely know that there will be an issue with battery consumption which is quite acceptable... but with regards the OC itself, let me compare it to a regular desktop PC...
Say i did overclock my processor, there are definitely a possibility to fry the board or make it overheat, can the same thing happen here?

No i don't see any heating issues,
After OC if you properly configure setcpu
according to your use then battery life is not a big issue
And try internet radio apps such as spotify
or Pandora instead of spirit fm app

razodroid v2.3
razodroid v2.3 is the best which also has a oc kernel file which supports upto 801mhz and its very stable....+it has darktremour app2sd app so not problems of low internal memory...and it comes with a cyan coloured appearance which is also cool...the battery stays alive upto 2 days for normal use...the only dwarback is that when we change the dpi of the phone...the music app FCs...but dats ok.....
just wait for razodroid v4.0
RazoDroid 4.0 is the best (ADRENALINE SCRIPT)

CPU apps And underclocking - batter life?

I have a couple of question/advices I want to receive an answer for about CPU.
So I am struggling to get better battery life without hurting performance.
1) Can CPU apps hurt battery life by themselfs. I mean could only using an app not regarding the settings damage the battery life. Is it better to let the cpu work by itself and not any apps managing it?
2) Which is the best CPU control app?
3) Will Underclocking improve my battery life a lot and will it make performance worse. What are the best settings to keep battery life and performance optimized at the same time. If I want to play heavy games I will overclock for the time I play the game. But I don't want my cpu to be working at 1600ghz for instance when I am not doing gaming or similar heavy processes. What are the best settings to improve battery life but not hurt performance?
If you use an app like SetCPU, you can have profiles. I used to have it so that the phone would underclock when the battery reached a certain % or was too hot.
If you're S-Off and rooted, you can get way better battery life if you flash a new kernel. I'm using Faux v004, I've set SetCPU off and just let the kernel do its thing, and my battery life is at 1 day and almost 15 hours.
(I also play a lot of games and the Faux kernel is very resposnive. My games load much faster that they did on stock kernel)
Thanks! I am using this Kernel http://forum.xda-developers.com/showthread.php?t=1216197 and I find it good. I am rooted and used SetCPU in the past so I know all about profiles and etc. But my questions were. Do programs like SetCPU drain battery? And which best CPU program? And what about undervolting?

Apps like that don't really have any more of a drain than checking your email or receiving a text. If using Faux Kernel, there's an app out there designed for it that helps with clocking and undervolting it, made by the man himself. If not, AnTuTu has one on the market, I think.

Fauxclock hasn't been updated in ages and it's by Romanbb, not faux, afaik.
As for the OP's questions:
1. Not really. I haven't noticed any extra battery drain with CPU apps so it's probably not significant.
2. I don't think there's a 'best' CPU app. I used to use SystemTuner, which worked fine for me, but I switched to SetCPU because I wanted to underclock the intellidemand governor on faux's latest beta.
3. Underclocking will lead to some improvement in battery life. As for undervolting, some people say it helps, others say it's a placebo; personally I've never bothered with it. You could try using faux's kernel with the intellidemand governor, which sets the clock speed (and whether the second core is online/offline) depending on the CPU load. As for best settings, it depends on each individual kernel and your own personal needs, so you might want to try flashing a few custom kernels to decide which one is for you.

Hi,

You cannot get away from that.
How long have you had this ROM and kernel.
You need to give them time to settle.
Battery works best after several cycles(charge/discharge)

It tends to get warm because CPU need to run quicker instructions.
If its sensation then bear with the slightly bad battery.
Because its a 1500mAh battery but needs to hold up a 4.3 screen.
Lower clock speed clean background apps before playing. It helps at least a little.

If you're not crazy with games you can downclock it to below 1000ghz. Its more than enough for most apps.
As for your system language, post another thread would be good.

Can someone suggest better kernel and configuration for better battery life please?
I have tested a few kernel and with each have same results:max 12-13 hours battery,with only 1-1,5 hours of screen on and normal usage(just 10 minutes of gaming,~40 min. voice calls,~10 min of facebook and few sms).At all kernel max cpu was 1188 and min cpu 192, no GPU overclocked.I tried this:bricked v1.36,sultan v19.5 with badass governor , faux with intellidemand and sebastian with ondeman (with this i have just 11 hours of battery).I am on darksense v1.2.1 rom.What seems to be suspect is cause when i use phone,battery drain so much and when is locked battery remains intact.Thanks and sorry for long post.

Hi,
It seems you are going the right way about it.
No 2 people use their phones in the same way,so battery life will vary,and there is no single setup that will work for everybody.
Keep trying different combination of ROM and kernel.
But give them a couple of cycles each,otherwise you will not see how they work properly.

[Q] Does it really save power to reduce cpu frequency

We use kinds of kernel and cpu tools ,does it really save power ?if so,which kernel do you think is the best..Thanks so much
I like PA rom and i just want to know which kernel would be better......
Cant say whats best kernel. Kernel is fone depended. Some kernel work well for some ppl but wont work with others. The most popular is BMS and KT747 kernels. Give them a try. Im on bms stock battery get about 13-15hrs with 7hrs sleep mode and 3-4hrs of screen time

Undervolting is over rated. If lucky may gain 30 minutes on a complete charge/discharge cycle. Too much can cause reboots and/or increase battery drain.

i see,thanks very much:sly:

IMO its pointless to mess with the CPU settings in order to save battery. Seems like the major cause of battery drain is always going to be screen on time.

battery drain

hi i have the usual problem with my samsung galaxy S i9003: my battery drains extremely quickly. on the battery usage it shows that the display is what is draining my battry the most, but the problem is, it is on its lowest. i just don't know what to do, i wiped the battery stats, i downloaded lots of programs to save battery, i removed the google backup transport apk, i don't use wifi, 3g, gps, bluetooth, i don't play games, i really don't know what else to do.
so please, help me.
i bought the phone from another person, so it's been already used.
i'm on gingerbread DDLF2, i'm rooted and have already tried a few roms but had the same problem, if you know of good, stable, smooth and for daily use rom please let me know.
ps: my phone doesn't show real battery stats, what i mean is, when the phone is on 30% it just shuts off, and when i plug it and turn it on, it shows 0%. it has happened since the day i got it.
ps2: i don't know if this matters but, i soft-bricked my phone like two weeks ago trying to restore the stock rom from a remics rom, and flashed the stock rom to get it back.
the battery drain problem has been there since before but i just wanted to put it out there to see if it helps.

can you tell me for how many hours your battery lasts after fully charged.
battery usage also depends on cpu usage ( like if u have set your processor limits to high ) or may be because you have lots of apps running in the background. you can try installing watchdog application to trace whose eating up your battery

I experienced battery drain too on GB ROM. I guess that newer apps are using android functions that are not coded very efficiently on GB.
I was surprised that battery life got much better after flashin to 4.4 kitkat. If you want to give it a try, I definitely recommend trying out flashing your device and see whether battery life improves
yes.... can try out different rom or some other kernels too. and try changing processor to some battery friendly mode like " conservative " or tweak the default processor to save battery.
and try out greenify app if you are not using. @luligorla

my battery last for about three or four hours if not less. i'll try downloading that app, but anyway the problem here is that in battery usage in shows that display is what is spending the battery the most, when it is on its lowest, i just don't get it.

i'm rooted, indeed, but it seems i'm not finding that application or if i have to download one. i downloaded whatdog and the only alert i got was about the gallery using the cpu.
what i'm worried about is that the display is literally on 0%, isn't it weird?
i tried flashing 2 different roms and with both the battery drained just the same. if you know about any stable, smooth and for daily use rom please let me know!
