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

You can get a 2450mah battery that doesnt need a different case. Also try Android Assistant, you can view processes that are running and sort by cpu usage. Try to remove or atleast kill from startup any apps that do not need to run all the time. Most battery assistant programs do not work as after killing an app it will just load back up a few minutes later.
I got the official 2000 mAh battery which did give 15% more life. However the most effective improvement I got was from using the SpeedMod kernel and using Tasker to be more precise about when things came on.
Went from around 14 hrs stock to 30+ hrs for SpeedMod on stock rom for GB.

Hi,
To avoid too fast draining, some classics advices are to turn off some functionalities when you not need it, by example Auto Sync. Many applications needs to be configured with less frequent synchronization (weather apps or widgets, email apps, news apps...)
And as it was mentionned, some kernels can dramatically improve your experience. I agree that Speedmod is one of the best kernel to preserve battery. You can flash it easilly via CWM.

I have been struggling with trying to figure out if the battery life I am seeing is what my Atrix is really capable of. I am occasionally a heavy user, but on weekends I am a very light user. I'll start at 8am with 100% and be almost dead at 6-8pm. I have searched around and seen other Atrix users with 24 hours of battery life and even if I tried my hardest to not use my phone I wouldn't get those kind of numbers. I feel fairly confident in saying i scoured search results and tried everything i could find to extend battery life.
Am I doing something wrong?
Is there something I can do to help?
I know it's been asked before, but I am hoping to get some current answers for this question: what kind of battery life numbers are you getting on your Atrix? Which rom are you using?
Atrix 4G running CM7 RC3. If the answer is "keep it charged as often as possible", it is what it is. It would be great to find an answer to why battery life is so much shorter than others though! Many thanks in advance.
Just noticed CM7.2 stable was released, upgrading to that now to see if battery life improves. Might try a full wipe to see if battery life is better without email, syncs, etc. etc. if the upgrade doesn't help.
i would recommend getting cpu spy and also download and install as a zip 'blue sleep fix' (blue sleep zip can be found in the CM7 thread). This has greatly improved my battery life.

Which kernel? Flash Faux 1.0GHz and undervolt across the board by -50mv. Instant battery life!
Also, use ROM Manager or equivalent to stop all non essential apps from starting on boot.

You should turn wifi off when not in use, that will save battery life.
Badass battery will let you know how you spend your battery by % and let you know which app takes the most battery. (Lets you get a really readable easily understandable battery read out.)
I can help you get even better battery if you use this app and give me some numbers (it has a share via gmail/etc)

turning off wifi is not going to help him that much. I leave my wifi on all the time no problems, make 2 days light usage no problem.
More likely he's got some apps running around in the background. I suggest he pick through what he's got installed and start turning off the things that like to sync all the time in the background.
I think step number 1 would be to install a non-stock ROM and startover fresh.
Blur-based ROMs (Nottachtrix was really good) then the faux123 kernel then slowly start installing the apps he likes to use and monitor battery life. It might take a month but he's definitely got an offender here or there causing these problems.
also install Juice Defender. My mom's Galaxy S2 was having tons of problems with battery life even though she wasn't using it at all, 60% battery life at 3pm without using it at all, installed that and immediately helped her a lot, like 80% by 3pm WITH use.
Also, clear your dalvik cache. After installing lots of stuff and not using it, it just fills up with sometimes poorly written code. Clearing it always makes phone faster in my experience.

I think this is what I will do today! I'll do a nandroid backup, and try Nottachtrix with no extra stuff installed or setup. I will report back! I appreciate all the help to get my phone performing where it should be.
Just wanted to report in. I tried a clean ROM as stated in my previous post with no luck. I just couldn't get past the battery life I was getting with cyanogenmod WITH all of the apps and syncs enabled. Should I try another ROM maybe?
Maybe your battery is just a bit old? After ~2 years, you can expect that battery life drops dramatically. if you are a heavy user this might happen earlier. Maybe check with the battery of a friend of yours whether it's a software or a hardware issue
Nvmd
You could be right, the battery might be dying.
I was on vacation the past few days so I got the opportunity to not use my phone most of the day (job requires me to use the phone a lot). The battery lasted about 12 hours and looked like it had about 4 hours left. So maybe I am expecting too much, but I'm not trolling...no.
If you aren't going to be helpful, go somewhere else. You could have said "Your phone screen was on for probably longer periods than the average user and that's why you can't hit longer hours". Based on your previous comments, I shouldn't expect much from you though.
Many thanks to all who are helping me. You're all awesome.

Guys before flaming, try AOKP JB 4.1.2 Milestone 1 by Bytecode, you'll notice the difference in battery life. It's based on 2.6 kernel
actualy JAVA causes battery drains:
"What’s the worst thing about Android which iPhone does not suffer from? It’s battery drain. With the battery strength most manufacturers are putting in the phone, it appears, 3 years down the line we would need car batteries with the tablet and phones (I’d prefer carrying my CPU on head anyways)! This is one thing where iPhone beats Android hands down and proves its pure awesomeness! But we believe Apple hasn’t put any patent on that word so we can use that for Ubuntu Phone as well.
The reason Android sucks (the phone’s battery) is ‘Java’. Most hardcore tech geeks (aka hackers) call Java a pathetic language. We’d call it (and .NET) a technical eunuch – it is not compiled to binary, it is not interpretable as a script and what do you get – a false sense of security. Yep, under certain circumstances, it is beneficial but then (whatever happened to reverse engineering techniques) a Mobile OS and Java? That sounds like a troubled marriage. Java is one of the biggest reasons why Android under-performs. A significant amount of power gets consumed for the bytecode interpretation. Alright, it is technically not the bytecode as in Java SE/ME and is an optimized and converted version of the same which runs on the Dalvik VM but it’s still far from binary." from here http://www.c-integration.com/blog/showpost.php/75-5-reasons-why-ubuntu-phone-can-blow-away-android
FOR ME, ITS THE GOOGLE APPS, I FREEZE THIS, TAKE NOTE: GoogleServices apk, and GoogleServiceFramework.apk (you will see the wakelock named xxx-gsf or something like, well this is the app).. that works for me, but you are not able to use any app what uses google connect, like youtube, etc!

I'm using google apps on aokp jb, no battery drain
Well,in ics you can flash a 2.6 kernel.I used it too(4d kernel by S'n'S),but not because of battery,but in terms of performance is way better than 3.0.x.However I admit that on 2.6 the battery is a little better.You just have to optimize the phone corectly !

not necessarily direct battery drain..but cause Wakelocks which increase battery drain
battery drain is, I think, now native in Android, it depends only how bad is it, some gapps make wakelocks preventing deepsleep, and wifi that is really a big trouble with 3.0 kernel, and since we do not have an 3.0 kernel designed specific for O1 and has an increased battery drain(especialy wifi drain) did someone used an special app like SetCpu or CPUMaster that has profile settings for over/under clock that you can set to see if this app prevents wakelocks with 3.0 kernel ?
and, the battery drain is increasing as OC or no ? in my opinion it shouldn't be, or not? a drain is a drain and should be same or is exponential ?
so OC makes CPU drain more, gapps drains too, wifi drains, outch, poor battery, screen drains? cannot read anything on phone in daylight if it's not at max, what does more drain ? some funny apps installed from market for my kids (like Talking Friends, Talking Tom etc) why apps does not really close when you close them? here is an major issue, apps not really closing but run in background draining juice and creating wakelocks
so, my conclusion, EVERYTHING DRAINS BATTERY, oh, and does anyone remember if stock rom has battery drain? I think yes
And YES, the kernel 3.0 is a bit problematic, you notice the difference in the duration of the battery... the deepsleep is not working fine with that kernel!

i use DS battery saver which forces deep sleep and setcpu profiles.standby battery is great without wifi/3g
standby [email protected] 5-10% per hour.
while using 15% per hour..

OMG ...This kernel is maddening me...
@hariraj96, you're on JB, right? Try getting the Greenify app, then use it to hibernate problematic/resource consuming apps. I find that using Greenify along with CrossBreeder (performance & battery saving tweaks, found here on XDA) helped me get the most out of my battery when using JB (jenkins build).

This is CrossBreeder. It's a collection of tweaks/mods that, IMHO, works really well in smoothing out the performance and user experience of a phone like the O1. Simply flash the mod, and you're done, no configuring required. The governor tweaks and IO tweaks are disabled by default, though, so you'll need to enable them yourself (I find that enabling them helps with battery life slightly).
A caveat: CrossBreeder is incompatible with many other mods that do similar things (eg. V6 Supercharger, Seeder, etc.), so you need to remove those other tweaks if you want to try CrossBreeder. You shouldn't have too many tweaks installed at the same time, anyway, since you run the risk of conflicts.

Oxygen ROM, the best!
You, guys, never tried Oxygen 2.x by popdog123! It's actually the ROM which is the most optimized for our phone! Leaving the 3G on during the whole day, while being connected to my home router only spent 3-4% of my battery! Can you imagine how long your phone can be running on a single charge?! Trust me, this is a revolutionary ROM for our beloved smartphone
