Hello everyone, I recently went from the Revolution HD rom to the ViperS rom. I had flashed the radio and firmware required (stated in the rom's thread) for the Revolution HD and didn't see anything stating I should flash a different firmware when changing to the ViperS rom.
Now I have noticed my battery life has been reduced tremendously, where on the old rom I could get a day of general use this struggles to last 5 hours now. I have changed the governors and settings for ViperS and reflashed it many times but nothing has changed. Am I missing something here?
You might have to re calibrate the battery.. this can be done by wiping battery stats after a full charge in 4ext touch, or using a battery calibration app from the play store.
Hope that helps

Wiping battery stats is actually useless, it auto wipes every time it hits 100% and doesn't actually offer better battery life. To calibrate, just charge all the way up and discharge all the way down two or three times.

If I see another misleading post about wiping battery stats I will bang my head against the wall in frustration. I dont know how many times Ive said it, IT DOESNT HELP. A google engineer even said as much and gave a full explanation on G+ (google it if you want more info).
Sense 4 ROMs naturally have more battery drain than Sense 3.6 for some reason. To calibrate the battery, charge it to 100% then let it discharge to 5% then repeat 2-3 times. For some reason ROMs need a "settle" period
This is interesting because this Rom has given me the BEST battery life I've ever had in a Rom. Have you tried disabling the logging feature in the settings? This might help a bit. Also perhaps it does need to settle a bit. I've been reading and it's about 50/50 some are getting great battery life like me, others are not....I'm not sure what the differences are that some will get great results and others not. Maybe it's in the settings.also I did not flash the new firmware...

Okay I will give it more time to see if the battery just needs longer to adjust and I'll turn off logging.

I just root my phone last night and my battery is dying pretty fast without me even really using the phone.
Does anyone know if flashing a new kernel or any tips to conserve my battery?
Flashing a new kernel could help.

Always wipe battery stats in CWR Advanced>Wipe Battery Stats whenever you flash a new ROM. Also, you have to give it a couple of days to sort itself out. I've had ROMs lose 10%/hr in standby for the first day and they usually level out after a day or two. Especially CM7. Then try messing with kernels and whatnot. Just give every setup at least 2-3 days before passing judgement.

I assume you've verified that no rogue apps are causing battery drainage, correct?
Hai..
Im just switching to AOSP JB by AdamG Version 0.1.4.
No mod, stock AdamG ROM kernel, full wipe, just install few app such as whatsapp, cpuspy, medscape etc...this is not my daily phone..
the problem is very high battery drain..
in 4 hours battery drop from full charged to 69%..
Here the screenshot and BBS stats...Can somebody help me please to find the culprit??
Is Google Now on? it takes a ton of battery.

You need to install a better app. The Android built in power usage thing is about as much use as a chocolate teapot, and better battery stats isn't much better.
Try system panel from Play, you will need the paid version from here. Put it in monitoring mode and leave it for a few hours.
You will be able to see what is chewing CPU then, and that is invariably the thing that is causing the drain. It very rarely fails to assist me with diagnosis of an obscure drain issue.
Ok..just bought system panel app.will update about this crazy battery drain later..
Thanks thalamus..

Cool, it's well worth the couple of dollars.
I've used it pretty much constantly in monitoring mode since they were in beta when I had my desire. So, probably not far off a couple of years usage with me.
It doesn't eat battery either, because it polls when the device wakes up for another reason.
And the thing which really makes it good for me, it records usage of the system tasks, such as kernel threads, which can be massively handy in diagnosing an issue.
Solved by flashing latest adamG ROM..
Thanks adam and thalamus..haha..enjoyed my nexus s back...:thumbup:

i have a quick kernel question, i have cm9 rom installed and i did some searching and found that changing the kernel could help with battery drain, so im needing 2 know if this actualy helps. with cm9s kernel my phone only lasted abt 6hrs from doing nothing but txting (i have no apps on my phone except batteryxl/2xbattery. im not using the pro ver as i do not buy apps, so my wifi is constantly turned on even after i shut it off manualy and turn data on), i flashed the team faq kernel and still see abt the same, if changing the kernel does help with battery life, what kernel would be the best 2 use? and if possible could you link me to it. i have searched the sgs4g section for kernels but havnt found many in the development forums.
(if a question like mine was asked/answered b4 i am sry 4 reposting, as i am still trying to figure the best setup 4 my phone that will last atleast a full day or longer from just txting)

Atm there aren't any ICS kernels besides those two. You can try to under clock to 600 or 800 MHz to get a little more screen on time. Its either that or go to a GB rom with known good battery life
First off, have you read some of the other threads on battery life and ICS?
Second, what do those battery apps actually do? They may be doing more harm than good. BetterBatteryStats will provide insight into why your phone might be draining so quickly.
Third, turn off the WiFi! Not clear why you have it on if you're only texting.
Sounds to me that if it isn't one of those, it's new-shiny-toy syndrome, or cruft from flashing (if you believe in gremlins)

Battery apps don't do anything to improve battery life anymore. They were needed back around froyo and earlier but not anymore

I've had this problem once before and it was simply as easy as switching my kernel. You can see here.
Now I've tried GR to CM9 and then to Codename Android Build 4 still had the problem changed Kernels.. Then decided to GR to CM9 and try Beam, and yet again still had Android OS draining the battery. I then flashed the Hefe kernel and NO change.. I've looked around on forums and remember seeing someone mention strange battery stats I can't find it at the moment, but if you look at my stats below you can see that not only is the Android OS draining the battery the graph shows huge drop off points. What exactly are those? Thanks in advance for any help!

That looks like you need a new battery. A couple weeks ago I had the same problem. My usage looked the same as yours where there were sudden drops in the battery percentage. I suspect you have the same problem.

Try or buy Better Battery Stats. There really isn't anything that compares, either for features or support.

Have you tried clearing cache, clearing dalvik cache, then fixing permissions, rebooting and waiting at least ten minutes after reboot? That is what always fixed my "Android OS problem"

Yeah I've tried it all, and now I have replaced my battery and still getting the random huge battery drop offs. Tonight I'm going to GR to CM9 and then to codename and not restoring my apps

I started on stock GB, went to the 1 click stock with root and CW, to CM9, to Remi's ICS. This is what my battery looks like
@getochkn
Yeah, but you were sleeping or doing nothing, phone was idle. LOL Seriously, how is that possible? I have tried many ROMs, today I had a big issue on CM9, battery dropped from 60's% to 1% when phone got stuck and shut down. I had an emergency and needed my phone to call and couldn't. I got very pissed off and now I'm on GB because that battery drain issue has been all over ICS. I have tried calibrating, GR's, I use less apps... nothing! Phone lasted like 4-6 hours with average use. I needed to charge it like 3 times per day. It made my mobile phone, not so mobile.
Not complaining. Just a real issue. I know there are bugs and that development is ongoing. I love ICS but just can't afford to loss so much battery again in another emergency case scenario.
I would be happy to get 12 hours of use. I remember with Redux 1.2 (GB) I got 18-25 hours depending on use. Share some of your usage. I may need to buy a new battery.

Music for about an hour, wifi on most of the time, airdroid'ed into it, messing around with settings, took about a dozen pics.
Hello everyone and thanks to all the developers for the knowledge.
I've searched in the forum but still can't find the answer, so I have one question:
I bought a new battery, wich is still in the blister. I've already flashed my phone before (specifically Infuse 4g) with Custom Rooms, and had no problem.
My question is if it's good to use the new battery and flash the cellphone after charging it completely (i've read already battery university and pages like that for the health of the battery), or, if is it better to keep the actual battery, then flash, and then change the battery for the new one.
I know it's possible to re-calibrate the battery after flashing with programs, but I also believe that the first charge it's extremely important for the new one, and the stats for the previous one might affect the new one.
What would you recommend?
Thanks.
I think it's good to use the new battery and flash the cellphone after
charging it completely
You should def go ahead with the new battery.
There is nothing related with battery and flashing roms
Only sometimes you may get calibration problem which can be simply calibrating battery by using battery calibration app from playstore or deleting battery_stats.bin file

It doesn't really matter to much when you flash the rom, just i would clear the battery stats after you flash it just to be sure.
