hi guys,
i'm having some problems with the battery life of my LG P500 (with CM7 + Kernel v18.1).
i installed this custom rom because some people told me that it has the best perfomance. But what I see now is a bad battery drain...
what I have to do? Change the CM? The Kernel? Or what?
unfortunately, i accidentally deleted the backup file...
thanks!
After you install a custom rom you need to first wipe your battery stats from your recovery then you can also use battery calibration app also you need to give your phone some time to get used to the performance for the battery life to be accurate you can see this warning in a few roms and in francos kernel thread the performance is better and the battery life is better to issue also suggest turning off your 3g when not using it if you have a 2.3 rom then you can go to cyanogen mod settings if it has it and add it to your notification buttons my battery on medium to heavy use will last 24-36 hours where with stock rom maybe 10

thanks, man! =D
well, i don't use 3G... i keep this turned off. ;D
so, this is the only thing that i can do? Wipe battery stats?
i did this right now... let see...
There's not much you can do that has actual effect on the battery life. Keep wifi & 3G off when u don't use them is usually the first advice. Unfortunately overclocking means that your battery will drain out very fast. Mine's on charge via USB-cable most of the day, and using wifi or playing games for 40 mins means at least -20% battery power.
i know about wifi and 3g... ;D
and what about custom roms and kernel? my cobination could be a problem? =\

CM7 (6.5.5) comes with franco's kernel, and as far as I know, that's the best one at the moment, so I don't think that is the problem either. it's just how this ROM is ... you're not the only one with the same problem lol
how many things are you running in the background?
I've had issues with a couple programs eating cpu in the background.
oh and brightness makes a large difference.
if you have missed message flasher running by either flashing the screen or vibration's that will also drain the battery fast.

this is something that i'm really looking... the apps that are running in the background... and something that i think very strange is the maps app... it is running though i didn't open it... o.o
the same thing happens to the equalizer...
they run without i know... so, i go there and cancel them. =s
flashing the screen or vibrations i have disabled. ;D
thanks!
if maps is running that is what is killing your battery .
if you want maps
get titanium backup and backup (or if you have paid freeze) the app and restore/unfreeze when you want to use it.
Yes Maps can drain the battery a lot lol
ps. you can see what is using your battery if you goto
settings ----> about ---> battery use
Lucky you can turn off 3g I'm on a provider that won't work unless I have it enabled -_- lol
My main reason for flashing a custom ROM is the ability to change permissions for each app that has been merged into CM and is part of mik's port. That combined with droidwall is a very important tool to battle the privacy violations with so many apps. That means that I didn't overclock, but I still saw an incredible battery drain on 6.5.5 + 18.1. Plus I was getting a weird log error with droidwall. I appreciate all the efforts on behalf of the developers, and I really hope to get a stable rom that would let me modify permissions of all apps with good battery life. Everything else is secondary.

Google maps will not drain battery until u have data enabled,same applies for other processes running in background.
And overclocking also doesnt drain battery faster as said on franko tweaks page.
(Correct me if i am wrong)

False, read this about overclocking and battery, analyze the chart
And with google maps plus other similar apps running in the background, it will try to connect and find a connection therefore draining battery.
processes that only run in mine are:
google services (1process, google messaging service)
android keyboard ( dont tell me u dont know that )
pretty much those are necessary for your phone to be functional.

I got OC info from this page.
And abt maps,i have stated that it will not consume battery when data is NOT enabled.
Anyways thanks for those charts.
But as per my personal experience,OC doesnt drain battery faster
Use v18 CFS, not v18.1 .. i had the later and the battery drain was huge. Switch to 18, charge to 100%, wipe battery stats, use until completely discharged then charge again and see if that helps. OFC not even v18 can compete with the stock (or even mik's kernel) in terms of battery life, but if you want performance...
For me the best option was mik CM 6.5.5 and fk v17 cfs!! Definitely feels stable all the time!!
thank you, guys!
well... i really made a little mistake... the battery life improves with the fkv18 cfs. isn't a awful improvement, but is something.... =D
should i change to v17? =s
how i can see, CM 6.5.5 is the best option...
thanks!

Hm, i thought devs like andy and a couple other devs mentioned it before that g-maps & other similar apps will consume a %tage of batt. It's similar to bgsyncs. You can see for urself and log then block it with droidwall.
let's say:
you got every connection off (wifi, 3g off, only 2g for messages/sms otherwise none) > g-maps running > it will TRY to FIND a connection at a specific interval e.g. ~20min. > therefore consuming resources. I dunno about the latest versions of google trashes though (maps got offline support)
About oc'ing, yeah 122-480ish consumes the same BUT not if your phone is demanding more cpu to complete tasks, i.e @ 122 clocked it completes the tasks at a longer time than 320 wc is fast, just balance it if you are gaming or just using it for web browsing/sms/calls/music/minimal gaming like me( ~2.5 days atm im on 320/729 v18 bfs smartass & it's good enough).IIRC franco told this on his earlier pages on the kernel topic

Correct me if I'm wrong but for a 2.3.4 rom shouldn't you be using the BFS version of Franco Kernel? I believe that CFS is for Froyo roms (at least that's what Franco himself told me on a post a few weeks ago)

Hi Guyz,
I am using optimus one for the past 6 months and have 3 major problems..
1. Scrolling in Launcher pro which was silky smooth once upon a time stutters a lot now a days. i tried different roms, posted a thread on this forum , tried the suggestions but still the same issue exists. When the rom is new, before my set of apps are installed, launcher pro works smooth. but once my apps are installed, it gets back to stutter pro. PLease help
2. Battery drain. - I used to get One and half days of battery without the data on. Its been a week since i subscribed to unlimited gprs pack and with the data on, on 2g mode, with auto sync off, my battery s drained a lot. even in stock rom, it went down from 70 percent to 8 percent in 7 hours. with franco kernel. I also tried froyofinal, void, lol, mik gingerbread, stock gingerbread roms and .. same results.... i used facebook and downloaded a lot durin tht 7 hours. is tht normal...?
3. Minor issue.. When i lock the device and then press back key or any other key after the device is locked, for a split second i get to see the desktop and then only the lock screen appears. some times i used to see a blurred dotted image(we get it wen the cable connection is off). and then the lock screen. This issue exists in stock rom with franco kernel itself... Y?
Please help guyz.....
1. You say once upon a time your launcher pro was smooth. Try reverting to the same configuration you had then and see if this issue is fixed.
2. If you did downloads, then I would say it may be normal. Keep it idle, i.e only a few calls and sms and then see the drain.
3. This happens in franco kernel. Small issue.
make sure u dont use live wallpapers.. they really screw up the phones performance..
for battery drain its.. quite good.. if u downloaded a lot. calibrate battery and then try once again.
i would say u should try miks 6.5.5 with fk v18 cfs.. it gives best battery life with 2g.. and has best performance too
I tried mik's Rom . Still the battery drain is noticeable. And more over the call volume s too loud . Is there any way to reduce it .
And i also calibrated the battery and i don't use live wallpaper. Any other suggestions

J.k signing off using XDA app on OPTIMUS PRIME
Any live widgets that you use, they do contribute lots in battery drain
Use startup manager and see what apps are loaded on startup and remain in memory there might be some you will like to remove, maps also causes lot of battery drain, remove it from startup

I'm also facing this issue. I'm using CM7 6.5.4 with v18.1 Franco's Kernel. People have said v18.1 kernel had very bad battery life and I am experiencing this like everyone else. The performance of 18.1 is amazing, but battery is being drained to fast. I'm going to revert to a lower version of the kernel and see if battery life is better.

That right there. You are obviously installing one or a few apps that are taking up much CPU. You need to try and scale back. I would install your apps back one at a time until you find what app(s) might be causing your stutter.
And quit bumping your topic 2-3 times in a day... FFS people will get to you, chill....
hi just wanted to ask if there is a ROM there that is as close as the original ROM of the samsung galaxy s II in terms of apps and looks but is tweaked for better battery perfomance?
cause my dad bought a SGSII almost a week now, and we only get about 5-6 hrs of it using only it. already did about 4 charge cycles. (4 only cause most of the time the GSII is off, my dad's getting a hang it yet)
config:
- stock android 2.3.3
- 3g auto
- auto backlight (but we are inside a mall so the backlight is isn't that bright & have strong signal)
- auto sync is off
- background data is on
- haptic feedback is off
- audible selection is off
- fast dormancy is off
- power saving mode is on
- juice defender app in balanced setting
apps running:
-skype
-messenger
it drains a LOT even in standby a lot more when using it (browsing, not yet chatting). my hd2 is much more efficient knowing it is not a native android smartphone...
is there a tweaked battery efficient rom there that is as close or at least still looks as the stock?
You can do three things,
1- Install Better Battery Stats and see under 'Partial Wakelocks' to see whats running on background.
2- Stay on Stock ROM and flash a kernel which allows Voltage tweaks and install SetCPU and Undervolt CPU. Ninphetamine 2.1.3 is such a kernel.
3- If thats too complicated for you, then flash an Undervolted kernel, like SpeedMod.
I won't advise you to change to a Custom ROM for battery backup betterment. But doing the above processes will certainly save some.

thanks for the quick reply, so custom kernels work with the stock rom...i thought it won't. i'm not that familiar yet with native androids cause in HD2 most of the undervolted kernels there are already built in the roms so i don't change it that much now with the NAND builds....but anyway, i'll try for the mean time # 1 & 3....i'm not that into that #2 tweaks yet in a phone that is not really mine....
It is proven that Stock ROM's with custom Kernels have sweet battery life. As with Stock ROM's they haven't tweaked anything, it's just stock and you flash what YOU want, whereas a custom ROM you're getting things you dont infact need.
I keep going back and forth from Custom ROM's to Stock ROM's.
Hi
I would also recommend looking at SicOpat's ROM (http://forum.xda-developers.com/showthread.php?t=1183774)
This is essentially a stock, rooted ROM with a custom kernel and I find it exceptionally good.
The other thing I would recommend then is to install Titanium Backup and freeze/uninstall a lot of the Samsung apps - WiFi Sharing, software update, *hub stuff. Removing these has a very positive impact on battery life.
Hope this helps.

I have also been troubleshooting poor battery life on my phone. I used to lose 10-15% an hour just idling. I reflashed Stock KH3 with the KH3 CF-ROOT kernel and reinstalled a few things (twitter, yahoo messenger, google voice, and some apps that don't sync data). Currently I had 18hrs now with 60% left. MUCH better. A lot of the time the phone was idle but I did listen to music, play some games, and browse the internet/chat, use wifi a bit. Phone only lost like 4-6% overnight. (sorry I don't have hard figures but I didn't document any of it on paper). I'm trying to find out what was killing my battery so I am installing things little by little but I would definitely recommend stock KH3. Seems great so far.
I think your problem lies with the wifi-sharing battery bug. I hear this is updated in newer roms. This was the biggest battery hog on my phone, but after noticing it, my battery life is excellent now.
When Wifi is turned on/off this erroneous process starts in the background called "Wifi-Sharing". It hides and drains your battery at a VERY fast rate. The remedy is simply to "Force Stop" this process after you use Wifi.
Let us know if that helps.
You could root the phone and install Titanium to freeze this process permanently.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
sorry for the wrong forum i got messed up in opening a lot of samsung galaxy sII threads....
i dont see the "wifi sharing" in my dad's GSII when we used it. and as with kies, i think JKG2 firmware is the latest, so i assume that the wifi sharing bug has been fixed there, yes?
i know it would consume a lot since the GSII has a big "engine" but i didn't expect it to eat a lot even on standby with only YM and SKype messengers running in the background.
i'm still observing it. i'm still running stock.
EDIT: i just used wifi to download an app then when look for running apps, i saw "wifi-sharing" is running but i didn't even turned it on
i just flashed Speedmod T38 kernel (it seemed less complicated to use ) now observing if my dad's SGSII gets better
I'm a new Galaxy S II (and new Android) user, and am a bit disappointed in the battery life of my new phone. It was running down extremely quickly yesterday, only lasting about 12 hours with relatively normal use (sending half a dozen texts, downloading 2 apps, checking Facebook and Twitter once an hour or so for a couple of minutes throughout the day). I allowed the phone to discharge completely and charged it fully last night, but this morning nothing seems to have improved. I burned up 10% of the battery in half an hour sending 2 texts, checking my emails, Facebook and Twitter and downloading and trying out a couple of apps.
I'm anxious to know if there's a bit of a burn-in time with the battery on this thing - does it get better after a few charges? I see a lot of people saying they can have the phone on for a few days in some cases, but that's definitely not my experience thus far.
I've installed JuiceDefender (balanced profile), AutoKiller Memory and Advanced Task Killer to try to sort things out but none of them seem to having too much effect and to be quite honest I'd rather not have to compromise my experience by running a number of apps like this to try to extend my battery life at all (nor do I want to have to turn the brightness right down to an unusable level, or set black wallpapers for example).
Does anyone have any real advice on this? I'm starting to think that switching ROMs might be worthwhile? I see that the leaked 2.3.4 ROM seems to have better battery life - is this correct? I'm a bit reluctant to switch to any other unofficial ROMs as there are so many I wouldn't know where to start. It seems they all make a lot of changes but I'd want to keep as close to the stock feel as possible, just with better battery life.
no one uses stock roms/kernels nowadays. u should flash a custom rom or kernel since they provided optimizations to batt life.

It is argued that task killers and memory killers will only make the problem worse. Juice Defender might be useful if you are using it for scheduling sync and turning WI-FI off when the screen is off, but this feature is only present in the Ultimate edition and you can turn off sync and WI-FI manually if you want. Also beware of rogue apps which are syncing all the time. It is normally the main reason of poor battery life.
Other reason, is that whereas powerful tech specs for phones were rapidly developed, battery technology didn't followed the pace. Our simply batteries cannot cope with our beasts.
Also, there is a thing that it's called "new phone battery blues" which is described as poor battery life due to excessive use of a new powerful toy. After you use your phone normally, for the purposes that normally people use a phone, your battery life will became better.
That said, personally I have a spare battery and a spare charger, and when the battery being used is low, I replace it with the charged one. Sometimes it is necessary, sometimes not.

They also have a tendency to look very tacky I think though. I think Samsung's skin and widgets are pretty nice and don't care too much for the mods I see in the screens of most ROMs. I'm really looking for something very similar to stock, except with better battery life if there are any suggestions? That's why I was thinking of just jumping to the leaked 2.3.4 if it had any noticeable impact on battery life...
Try using better battery stats, link in my sig, to see if you have any wakelocks, the thread has a good howto on using it.
The biggest thing that uses the battery on this phone is the screen, you will get between 4 and 6 hours of screen on time depending on usage and screen brightness.

Fair point - not all of the roms are everyone's cup of tea. My advice, as a starting point is to flash the stock XXKH3 variant for your area, and then flash a custom kernel, such as Ninphetamine's or Hardcore's Speedmod. This will greatly help with battery life, and also give you the ability (via root access) to use Titanium Backup to freeze apps and services you're not using, which is often the major cause of battery drain through 'wakelocks'; apps that prevent your phone from entering Deep Sleep, or continuously wake it up.
Update to the latest version in your area, uninstall those task killers and whatnot or do a factory reset, install the apps that you are going to use normally like facebook twitter and install better battery stats, decrease brightness to your most tolerable level.
use the phone normally and when the battery is low, use the tool provided in android to check if your phone is sleeping when the screen is OFF, if you are having wakelocks, then use better battery stats to find which apps are causing the wake locks.
No need to install battery management apps, or task killers or memory optimization apps (or as custom rom as yet), that would only compound you problem which may be a very small one to begin with
Thanks for the help so far guys. I've installed XXKH3 and flashed hardcore's Speedmod kernel, and am just getting things set back up the way I like them again. I'm going to uninstall the battery saving apps for now and see how the battery lasts the next couple days.
I'll install Better Battery Stats and keep an eye on any wakelocks too.
Thanks for pointing me in the right direction - it was all very simple and quick to get set up; the sheer number of kernels, ROMs, etc. is all a little overwhelming to me right now, being new to Android!

there are other tweaks with custom roms that aren't found in the stock rom (which provides better functionality).

wow, good for you
I used HTC Desire before this device, and the roms on there actually hindered battery life, even with all the fancy underclocking, so I am betting, without even attempting to brick my phone, that they are just as overhyped on this phone too.
I get two to three days out of my phone, using it as a PHONE. I can send and receive emails and texts all day, along with phone calls and the occasional browsing and still get at least two days before it dies. I turn off data when I dont want it and stick it in 2G mode and it dares me to kill the battery.
Just let usage settle down and it's fine

Beware using anything that isnt ondemand on samsung phones, can cause stuttering, that's what I found anyway.
As far as undervolting -25 to -50mv is a safe first bet.

That is wrong. I used to have a UGKG2 ROM and since I upgraded to XXKH3, the battery is MUCH better while the GPS pinpoints in less than 3 seconds with a 5meters accuracy.
When i was using 2G the battery life was good for a whole day. How i have switched my connection to 3G, the main problem is the battery life as it drains in a half day. How can i control this ? which application is draining my battery life? what are the other systems that can save the battery life and extend it to a day time when using 3G????

There are several threads for this topic.
Why don't you post your question there?
Maybe there is already a good answer for you?!
My recommendation is to calibrate your battery (e.g with BatteryCalibration app from the Market) and un-install all apps you do not need.
Maybe a Task Killer app (I am using Advanced Task Killer from the Market) can help you to eliminate some battery draining background apps.
If that does not help in your case, you can check if your mobile provider supports fast dormancy. If not, you can try to disable fast dormancy in the settings menu appearing after dialing *#*#9900#*#*.
What ROM, kernel and modem is your phone running on?
There are some versions which are better for battery life.

Why don't you post your question there?
Maybe there is already a good answer for you?!

When i was using 2G the battery life was good for a whole day. How i have switched my connection to 3G, the main problem is the battery life as it drains in a half day. How can i control this ? which application is draining my battery life? what are the other systems that can save the battery life and extend it to a day time when using 3G????

When I use 3G it drains my battery a lot quicker but that's dependent on a lot of things so it's hard to pinpoint what is wrong.
3G is not as widely used as 2G, well in London anyway, and it'll use up lots of battery trying to get a good signal.
3G uses way more battery than 2G or Edge in general use.
I suggest only using 3G when you need to and don't bother with task killers - they use more battery than they save. I use an extended controls widget to switch between 2G and 3G, and also use Tasker to turn on my data every hour for 5 minutes.
As the poster above me suggests - root your phone, install a custom ROM and a kernel such as Speedmod and try a few modems.
I easily last a day or two now with moderate use so search the development sections on xda to find one that suits you.
Hope that helps.
Find the app Betterbatterystats in market or here on XDA and have a look at the partial wakelocks statistics. They show the apps that keep your phone awake. Try to find better settings for the apps with the highest count.

Had downloaded and installed and extended controller for 3G, let me see how it works...
Also is it good to root the device rather than having the factory settings????

Its good root the device if you want to try custom ROMs and kernels. Some are highly optimized for better battery life.
If you do root give VillainROM a go. It looks exactly like stock, is very stable, offers good battery life and has a few themes available for it. I've been running it for a while with speedmod kernel and I'm very happy.
Sent from my GT-I9100
Tried practically every rom under the sun, now back to stock 2.3.5 rom with speedmod kernel, seems the best for battery life, no need to calibrate batteries, this is a myth, simple use for a few days, and all will be well, stay stock, root then try out kernels is my advice.
Oh yes you can do the fast dormancy thing, not that it makes a lot of difference
Calibration of the battery does indeed help. My battery lasted for only 12 hours (100% batterydrain in 12 hours!). This went on for 3 days. I then calibrated the battery through clockwork recovery, without changing anything on the phone. Afterwards I was back to my usual couple of days of batterytime.
I'm currently using CheckRom RevolutionHD, Hardcore Speedmod Kernel k2-12, fast dormancy off and I'm getting quite good results regarding battery life and performance (lost about 1 percent in 8 hours on standby; WIFI always on).
I only calibrate my battery, when I switch to a new romupdate.
Disable fast dormancy could be a bit helpful, if your carrier doesn't support it.
