[Q] [i9000] Team ICSSGS RC3.1 - Battery Life

Hello everyone!
I've installed few days ago the onecosmic's ROM RC3.1, beatiful, perfect, smooth bla bla.
The problem is: i'm seeing so many post of people saying that with full charge, phone can stay alive for an average of 1 day- 1 day and an half (24-36h) with a normal use.
My phone can last 13-14h staying most of the time in standby and it's the 5th cycle so should be "stabilized" now. 1st cycle was awful, 8h (didn't expect anything else), then things got better but i've reached this cap of 14h.
I've tried Fugu kernel at first but i didn't get much improvement so i switched to paul kernel and changed modem too (jvk->jvt).
Still can't reach the dreamed 24-36h, i mean, i don't care about having 2 days of battery life, i would like to use the phone without having to charge it in the middle of the day.
btw nstools installed and set Deep Idle on, which seems to works just fine for me with the paul kernel.
(can't post outside link -.-)
nstools stats:
h*tp://i44.tinypic.com/6duvzb.png
does these stats means it's working?
i'll post also CPUspy stats:
h*tp://i43.tinypic.com/35052qf.png
is it everything ok here?
On standby there's no battery drain effect now, but when i'm using it, i get 1% down every 1-2 min.
What do you guys suggest? do i need to try other kernels/modems? shoud i try to flash again?
p.s. on 2.3.5 stock i used to have 24-36h but there's no way i'm going back to GB, i love ICS.

I used to have 24h of battery life, but I don't know what happened, after a week or so now my phone is draining 20% every hour, dead by noon...
Tried NStools with undervolt, and it didn't change anything.
It's now an useless piece of junk... this is retarded, either i will try reinstalling ICS or im going back to GB.

maybe your problem is caused by an app, or more than one, which are using push notification, you sould try uninstalling some...
Tried undervolt too, i got maybe an hour more.

Update: i just flashed again with RC3,1 and paul kernel. Situation seems a little better, gonna update again after few battery cycles.

What thing is in the battery status menu?
If it is media server: settings-->apps-->all--> Mediastorage-->force stop(dont wipe data)

sure! with the new paul kernel the battery life is better! amd now i'm trying the last glitch...my phone seems to work better...!i will hope to have also a good battery life without hard drain (with didle support maybe it's possible!)

actually, there was a lot of "Android OS" usage, maybe something went wrong from the beginning, the phone wasn't going to deep sleep state when put on stan-by and use more cpu than necessary when active, that must have been the main issue.
As i said, installed RC3.1 again this morning now everything is gooood
Lots of facebook, whatsapp, camera and 1 call, still have 67%. When put on standby battery almost doens't drop at all (checked on battery graph).
I think it's solved

I've the same problem. my battery life sucks...
Now my question. Where can I find/download the paul kernel? I#ll re-flash it too .
And my second question, do the "devil - der teufel" kernel do a great job too?

dunno about devil kernel, i read that for someone is even better than paul and it solves also "green screen" issue that appear when you lock the phone. I'm happy with this config so i won't touch it until RC4
I confirm that ,now, when my phone is in stand-by, battery usage is almost 0.
btw paul's kernel can be found here:
h*tps://w*w.dropbox.com/s/ts8j2o7wuklq9zg
(sorry about the "*" in the url but it won't let me post link 'til i get 10 post -.-)
is also in the first post of the Team ICSSGS rom btw

I have flashed RC3.1 yesterday, it lasted for 8 hours. I was using it heavily to check all the features, syncing the contacts etc. I have drained the battery fully now. Will charge it upto 100% and see how long it last now with normal usage.

thank u
i'll try it today and pray for a better battery life...
when RC4 is out than i think i will try the devil kernel... but until that i think "paul" will make it ^^

Battery Drain
hello everyone - I have been searching a lot abou this i9000 battery drain on ICS. I am using ICS and Devil karnel and battery lasts for around 11-12hrs. My usage is pretty normal. I dont use phone for most of the time but still it reaches to 12hrs mark. If I check battery stats then Android OS and Display (brightness is very low) are consuming most of the battery.
Please let me know if there are any ROM Tweeks or any other way to increase battery time. Or I will have to go back to GB because I hate charing battery two times a day.
Thank you.

[Q] Battery health

Hi, I would like to know the best way to measure my battery health. For about a month my battery starts to drain fast. I know my phone is already old and battery don't handle the same charge, but I have recharged the phone all night long and in ten minutes using wifi to just update some apps the battery just gone.
It is just ridiculous as I don't use any different configuration.
To be more specific, my phone configurations are:
- Cyanogenmod 7.2 by vo-1 (31/06/2012) deodexed by me;
- Firekernel Unnoficial OC (22/07/2012), CPU governor: smartassv2, max 787, min 245;
- Adrenaline Engine 4.2b;
One more thing. I was facing the same problem with blackhawk kernel.
I just think a battery can't die a sudden.
Could anyone help me with this?

There are a few things that can be causing this, but the first thing that you can try is to wipe your battery stats using "BatteryCalibration" app. After flashing a few things, it's best to do this. I had the same thing happen after flashing my third ROM or so.
After that, it basically comes down to the apps and widgets that you have running. Shut them off with a task manager so they don't end up draining your battery, but it might not be that either....
The only other thing that I can think of is that I heard in another thread (I really wish that I could find it again ) that the ace has a motherboard fault that causes it to drain faster than usual.
Other than that, all I can say is that the Ace generally has poor battery life, and it really does suck, but I don't really know how much more you can do. You could try flashing a stock-light ROM and see if it does the same thing (wipe battery stats too). But I would say is that you should try wiping the stats and see if anything changes.... Other than that.... I`m out. Hopefully it helps, and if it doesn`t, you might need to take it in (Service Center or wherever you bought the phone).
Maybe try searching in other threads (as it is a common problem) but besides that, goodluck :fingers-crossed:

I forgot to mention but I already did the calibration, using the app and manually to see if I could get different results.
I even tried to force a better charge, charging the phone off, waiting till 100%, unplugging and recharging, till the phone gets 100% again.
Ace's battery isn't good, but a month ago my phone was holding 12-14 hours without charge, using wifi a lot, that's why I think something is wrong.
Well, I'm flashing the original stock rom to see if get some change.
Thanks about the motherboard information, this is new for me :good:
Gonna see tomorrow if the battery holds better with the original stock ROM.
Thanks again!

Wiping the battery stats is a myth. All it does it clear the battery usage screen!
Android has a built in tool which can try to check the health of your battery.
Open the dialer
type *#*#4636#*#*
then go to battery information
Look at battery health.

Feedback
Just to give a feedback, my battery was really damaged. I bought a new one, stock because I didn't find other, and the phone now easily last a day, even using wifi a lot.
But that's not the only reason why I posting here again, I want to share how my old battery is. Comparing with new one, I realized that the old battery had stuffed something about 5 mm
If you pay attention, you'll see the small deformation.
Don't know yet what could have cause this, but I think it was heat and bad recharges...
Thanks for the help :good:

I'd recommend you to use SetCPU to prevent this on your new battery. Set up a profile with sound notification when it hits around 40degree, and underclock it at the same time.

I faced a similar problem. Battery was hardly six months old when it died but it was my fault. I was running a wi-fi tether and continuously charging it for about two days. :silly:
Got a new one under warranty. Been a year with the new battery and just recently facing problems with it. 3G just sucks the life out of it.

OK I just got 3g on my phone (yay for promotional 6gb plans!). But yeah, the 3g definitely kills my battery. I used to be able to go two or three days with very little use. Now I can only go one day even with standby with my 3g enabled. As long as I can put my phone on to charge before it dies, its all good to me
Finally with my 3g going, I understand everyone else's pain with the battery life haha

Baseband_xmm_power wakelock

Hey I have a problem with battery drain..AGAIN! My battery drained over night abnormally, over 20%. In BBS paerial wakelock was audioout_2. I resolved that with installing an old version of viber. After that,the phone was working almost 2 days without problem. Then anothe problem occurred.. Yesterday,I charged my phone to max, killed wifi,cleared RAm,did the fast reboot.. Over the night it used 34% of battery!!! In BBS, partial wakelock it said baseband_xmm power! How can I fix that?
I have to say, this JB sucks! This never happened on ICS...

It seems to be tegra3 issue that randomly pops up. I've found no solution yet

i got this wakelock too, factory reset did not solve it

When I woke up and so the wakelock, I just rebooted the phone and the wakelock was gone,and so far it is not a problem anymore... But I still dont know what caused that...

I keep having this problem as well. Rebooting temporarily fixes it but it comes back after a while. A solution would be much appreciated.

Same for me guys, I would like to add that I'm using the Zaiben ROM; are you using that too?
The reboot didn't fix the problem on my phone

im using portuguese 20A, and i can´t get rid of this damn wakelock, sometimes it goes away with a reboot, but eventually comes back...

I'm on Asia 20A with the same problem. 26% lost overnight. Not good at all. In ICS it was like 6% overnight, lol.

Dunno but in official bootloader unlock thread it needs you to be connected to real network for some time then I would say there's a way to monitor that time and maybe this is it - maybe it disappears after bootloader unlock

my bootloader is unlocked

My baseband_xmm_power wakelock is showed in kernel wakelocks but in partial wakelocks there isnt any wakelock worth mentioning.. But over the day,when i turn wifi on and do a reboot it doesnt show at all..
Thats my biggest problem,it shows up randomly...

I have the same issue, 6.6%/h battery drain last night. And the big problem is baseband_xmm_power. I check my wife phone (not tegra device) and "baseband.." not even in the kernel wakelock. I read somewhere (forgot the site) it's tegra kernel problem, and after they install custom kernel the problem with baseband is gone.
I'm not developer but I wish lg will release kernel source now, so somebody can optimize the kernel asap

is that JellyBean 4.1.2 got bug?

It seems to affect a lot of the Tegra 3 devices, however, I owned two Optimus G's (they're not Tegra 3) and they both had issues with battery drain too and it also had to do with the baseband. I surely hope my next LG, which may be the Optimus G Pro, doesn't have these issues.

Battery drain problem

Hey guys,
from about two months I am a proud owner of a 4x. I really like the phone but I am having serious battery issues. It did not take long for me to get CM 10.1.2 Stable. The main reason was the bad battery life of stock 4.1.2. However, the problems continued in CM as well. I have baseband wakelocks, wlan_rx_wake wakelocks and whenever I leave network location on I get nlp wakelocks as well. I tried Werewolf, iodak and Optimus Prime kernels. Not one of them seemed to resolve the problems. I had a lot of faith in werewolf 8b, but unfortunately it rarely goes beyond the LG logo and when it does I do not get network signal. Can any of you guys recommend what to do to get a decent battery life out of my phone. I do not expect miracles from a 4.7" quad-core phone but I'd like to be able to go through a whole day without having to charge it. I rarely get more than 2 hours of screen on time.
Thanks in advance!

Then I will be glad to have contributed to this record! Joking aside though, can you tell me in which version of CM are the new RIL/baseband changes implemented? Are they in 10.1.3 or just the 10.2 nightlies?

Try slim bean (4.3) port for our phone... Used to last average 4 hours of screen time with max 700 mhz cpu and interactive governor, which was more than enough for texting and some light games, and also use greenify to freeze those pain in the ass apps always awakening the phone... Download bbs or somthing and post the results, if you want, so you let us know !

I use BBS to track usage. This night I did an experiment. I charged the phone before I went to sleep and left it with wi-fi on. After exactly 10 hours the battery was at 42%...The strange thing is that it was in deep sleep over 8 hours and there is nothing strange in BBS. I will do this one more time just to check that it was not a one-time thing and post the dump file. With the wi-fi off (and data off), the phone can idle for hours without loosing a single % of battery.

i have encountered similar error - my device does go to sleep, but if i leave wifi on, the drain is pretty sick, around 5% per hour (and yeah, the phone was sleeping like 90% of the time)

Same here, 89% deep sleep and exactly 6% per hour. That is enormous, this means that during the day (12h) you lose 72% of battery without even touching the phone...After all with a smartphone it is expected to keep wi-fi on during the day. Have you found a solution to that problem?

none as of yet. switching kernels may or may not help, roms too. nowadays i only use wifi when needed and have data on for push notifications.

horrible battery

Is it just for me? After a full charge the screen on time is about 2 hours.. Tried cm11 and other custom roms without luck.. When i bought the phone and wasnt on KitKat the screen could pass 4hours. Huge different!
In battery info the only program that drain the battery is the system it self . any tips?

check your rom and kernel, any overclock setting is active.
check battery usage to find what drain your battery.
Mine have 4h30 - 6h screen on (just wifi, without mobile data)

No overclock set.. Just the system thats drains battery..

@colors Battery life isn't as good as I think it could have been but at completely stock and with nothing on the phone the phones battery is pretty phenomenal, an idle Z1 will stay on for over a week, infact i've seen some phones with 19 days before now quoted within stamina mode.
Just took a pic of one in my workplace and it's saying just over 19 days, that's not too bad for a phone which is always on and capable of receiving apps via wifi (see picture attached)
I know that 19 days is excessive and no one here is ever going to get anywhere near that or even a week, unless you don't use the phone, the problem most of us face is the apps that we use and their footprint on our phones, affecting battery life and performance.
Take a good look at your apps and what you use and see what you could do without or what could be affecting battery.
A clean install will usually give you great battery if theres nothing on the phone to slow it down, eliminating apps one by one might seem mundane but it's key to great battery life, after a while you'll learn whats bad and whats acceptable.
Using the likes of CM11 could cause even greater battery drain as it's all custom stuff, not to mention that some things within the system aren't working as good as they could be, there is still a lot of work before things are perfect, double tap to wake for example is a feature which could cause massive drain.
Always perform a full wipe and don't restore anything via recovery, leave it as a bare rom until you can verify the ROM you are using is without issue.
Hope this helps
