Someone can explain this battery drain?
in a lot of roms based on 2.2.1 there is a big battery drain, in some other there isn't.

Reboot after unplugging from USB and battery drain is gone. For further improvement install SetCPU and reduce min/max frequency. I am getting more or less the same lifetime as with donut ROMs.

OK I have done.. but the problem is that when I use it 3 o 4 minutes (for example I install an application using a file explorer, then I read a message and then I come back to home) m battery get 5% lower...
In standby I lose 10% in 6 - 7 hours (I think this is normal).

I am currently without a computer therefore immune to this USB bug. I flashed CM6.1 to this and the other g1 and both suffered substaintial amounts of battery drain so I nandroid restored back to CSDIv4 and still the lowest frequencies and settings did little to combat the descending digits. So I tried this...
Recalibrated my battery
Flashed SuperWipe.zip
Reboot
Flashed SparksMod's latest
Reboot
Wiped battery stats
Unplugged...reboot
Battery lasted 23 hours the first day never seen anything like it.
Lifes great.

I'm using TMUS-G1-Froyo CM6 remix..
and I'm using the new radio with +14mb.
The rom flies but the battery go down too fast.
I'm using setCPU with 256 - 528 mhz while screen is on, 122 - 256 mhz while screen off.
If I go to battery use in settings I see
Cell standby 45%
display 28%
phone idle 22%
android system 3%
I don't think is normal... cell standby is the battery use by cell radio..
I wonder if the new radio give a big battery drain..

I got real excited when I heard about the new radio and hboot even thought that its exclusion was the source of the the battery issues. Haven't been able to try it as I'm without a up-to-date PC at the moment.
It would be real nice if I could find a seasoned dev who understands battery consumption. I thought the kernal was the main culprit but I've tried two different roms with the same kernal and one has notably better battery life than the other. So confusing.

I can't use my phone with this battery drain...
I will come back to official android OTA-AOSP 1.6.. with +14mb.
So I'll test if this kernel with 14mb is a cause of battery drain.
PS: I'm not a lover of rom customizations.. I think the official roms are the best.
The other are all too heavy. I'm not a fan of cm kernel, that is too heavy for g1.
I would see an official OTA 2.2 without customizations, so every one could customize as he want, and if he want.
PS: OK I flashed AOSP 1.6 using ezBiff_kernel to have 15mb (cause I have new radio and spl, so I can flash roms only using this kernel).
Result: my battery life is similar to froyo 2.2 roms... so the problem is:
1) Kernel? (ezBiff_kernel is based on cyanomod kernel... ... ... heavy as death)
2) New radio/spl?
3) My battery (I don't think so.. it's new battery. I buy it 2 weeks ago and in the beginning it works so well.. but then I flashed new radio/spl and new kernel for 15mb..)

Come now.. the cm pershoot kernels are super optimized so they don't collapse under the heavy as death rom that is usually on top of it..
I get mixed results with that kernel between testing and feedback.
A test phone can idle on wifi+2g for days on the stock g1 battery even after a usb unplug.. but on more common use with syncing services its not performing as well as I'd like..
Some of it is fixed with less swap/compcache or changing clock speeds 122/480 for most the speed but lower voltage levels. Also the interactive governor may work better.. I'm testing these ideas if results are good my next kernels defaults will use them.
Cm/pershoot have some interesting new power management code from other htc devices.. So hopefully soon all will be better. (I merged most of it to my kernel but there are some loose ends.. works well untill the phone locks up.. so no public release yet)

Ok sorry I talk without knowledge. I really don't know the effect of the cm kernel. I only know that all roms based on cm release, with cm kernel, are so heavy and slow.
I like your rom (2.2.1 AOSP) and I love your new way to get 14mb.
But I have this orrible problem. My phone has a lot of battery drain when I use it. With screen off, no problems.
I have never used swap or compcache in this days, and I also try different clock speeds (not over 528mhz).
The result is that when I unlock my phone, I go to settings, I see for example 95% battery. Ok, I return to home, I open a message, I return to home, I open contacts and I scroll some contacts without make calls.
Then I come back to battery settings and I see that is 92-93%..
in 2 minutes of soft use.. I think this is impossible. If I open stupids 2D games... ahah in 5-10 minutes my battery lose 10 - 20%.
I remember 1 year ago, with 1.6 (no cyanomod) my battery was good.
Now it isn't (I have a new battery).
Today I flashed aosp 1.6 with your kernel for 14mb (I have new radio&spl) but nothing... I lose a lot of battery percent as in froyo.
So I think problem is or battery calibration, or something to wipe, or cm kernel, or new radio&spl + your new kernel...
Now I'm recalibrating battery (is at 1% from 2 hours, I'm not using it.. ) then I will recharge for 8 - 9 hours and then wipe battery state, but I have done this process a lot of time without a benefit.
I'll try to remove the new radio+spl (so also using standard kernel) if my battery continue to lose percents so fast.
I'll keep you update on my "story".
PS: Sorry for my bad english!! XD
OK.. after a day of low discharging and a night of 8 hour of recharging, I wiped battery states, I wiped data-cache-ext ecc... I flashed aosp 1.6 and ezbiff kernel..
"battery drain" continue...
I will try tomorrow to reflash death-spl and old radio..
BTW, is normal for hours battery 4v at 90%?
On the back of the battery sais 3.7v... I thought 3.7 was the voltage for 100%
Update
I know this thread is a little old, but I ran into this problem as well. What I found was that the official US radio (2.22.23.02) used considerably more battery than the international one (2.22.19.26i). The other thing I noticed is that switching to "use 2G networks only" in mobile networks settings and disabling data over mobile drastically improved battery life.
I also noticed that wifi used a fair bit of juice so my recommendation is to disable wifi if you're going to be on the go for a bit, and disable data/3g if you're just going to be hanging out in the local webcafe, your/a friend's house, or some other location with wifi access for a while.
If you wanted to be ambitious and cared enough you could write a script to use as a shortcut on the home screen to do the swap automatically (detect which setting(s) are enabled and swap them to the opposite).
With those changes, you should get much better battery life. My thoughts on different Froyo flavors is that possibly different builds have different settings by default. Cyanogen comes with data and 3g enabled by default so this will quickly suck out your battery if you're running your 3g, 2g and wifi antennas all at once.
The stock build (1.6) got about the same battery life as I'm getting now with those settings applied. With either build, having all antennas on all the time will drain your battery very rapidly. Being a little more cognizant of the settings (perhaps you also had it set to 2g only on the stock build) you're using will significantly improve your battery life. And when I say significantly, I mean night and day (but the antenna version definitely does also make a difference... at least in my case).
Hello,
I'm currently running:
Slick2x-F V4.5 (android 2.2.2)
+
HTC Sense 3.0 theme
I'm not sure about my kernel, I haven't flashed it but one of the roms I used might have flashed it, not sure.
I'm looking for a good rom/kernel/theme combination which looks good, performs well and maybe the most important thing, gives a good battery life. A good battery life is about 15-20 hours with about 2-4 hours of heavy usage in those hours. I currently get around 14 hours using the phone heavily for around 3 hours a day.
The current combination I was looking at:
ROM: http://forum.xda-developers.com/showthread.php?t=1254359
Kernel: http://forum.xda-developers.com/showthread.php?t=1295486
Theme: http://forum.xda-developers.com/showthread.php?t=1178640
Will this get me good performance + battery life?
I can tell you one thing for sure: any GB based ROM will be less easy on your battery life, it seems like Froyo releases are better are that, ATM.
I am currently using Topogigi's ROM, with SP 1+2+3 applied, and have just flashed HP kernel SR1 so it is too early for me to say anything on battery life; beware, though, that the latest HP kernel has a very strong vibration even in haptic feedaback and this in my case messed with the 'tap side' gesture to move in between your text... I had to disable this feature or the cursor would keep randomly jumping to the left.
If you are looking for best battery life, stick with Froyo: using stock v10d I managed to use my phone for two entire days with light usage.

Thanks, I'll keep that in mind
for me, i use GR4 modaco(v20j) 2.3.4
Code:
http://forum.xda-developers.com/showthread.php?t=1181407
and the kernel i use neoblaze
Code:
http://forum.xda-developers.com/showthread.php?t=1200726
the combination is good, i get 6452 score on antutubenchmark(oc 1,4GHZ), and it's still using ext3
you can use horsepower kernel from spica check the development section. i think it's pretty fast support ext4 (haven't tried to flash it) and it's already stable release
Code:
http://forum.xda-developers.com/showthread.php?t=1295486
or you can use CM7.1 it's 2.3.7 and the function like bluetooth audio & fm radio already functioned
or miui or any other rom in the dev section. have fun flashing
I'd say that the most stable rom is topogogi 2.0 + all the 3 sp's.
Combined with the sr6 kernel from spica it is very battery efficient (About 1 day
and 14 hours with light usage).
If you want to get a lot of juice out of your phone then get a froyo ROM.
Just wait a few days untill v20l roms start popping up, they probably have increased stability + battery life

They don't... They only updated the ROM not the kernel so the kernel should drain the same amount as it did before (and from my experience that kernel drains a lot!).
I vote for MIUI 1.10.28+Owains tweak pack (with swiftextreme)
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.

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.
Currently using the lastest CM7 kang + Etana kernel. While i am pleased with the performance i'm not pleased with the batterylife.
I've been updating Kang and using custum kernels but my batterylife seems to keep descreasing every time i change something. Probably because of the multiple roms version/kernel tweaks which do not always like eachother.
I'd like to start over but before i do i'd like to know which rom/kernel combo is considered to be the best for batterylife + smoothness! Any recommandations?
Second question - i've read several threads about 3thparty batteries but none seem to be conclusive - is there a battery which beats the stock battery?
Did you calibrate battery after flashing ROM?

I use Owain's CM9 with Harsh Kernel and the battery life is amazing!
I got the best battery performance if i am using 313 baseband with 725 10d RIL. I also use WIUI 2.3.30 as a Custom ROM with ETANA - Kernel with LOC - DS -OTF flag ;-)
it happened to me when i first install cm9, even use match ril&bb , the battery die quickly even i do nothing . but after i install harsh' kernel,battery be normal .
so,i suggests you use another kernel for cm7, from top topic in android development forum. hope this can help

I am finding my X2 only lasts about 4-6 hours. i take a couple of fotos/video, use wifi etc and its dead so quick. i read about reseting battery and filling the cells with the OFF charge on Charge method. so far i have charged full while on. restart charge while off. its on what looks like about 95% and has been on 1 extra hour still not full. is it a bug?
ok so next i disabled alot of stuff uninstalled car home etc and run on 2g etc,
is there anything else i need to know for battery life.
i read a tutorial on this site had a huge list of things. ive done those so far.
just cant get the battery to charge full while off charging.
ok did a few of the battery mods used "juice defender" uninstalled car home etc.
on standby with "wireless left on" and sync left on. 10 hours 40 minutes..
is that bad. I THINK THATS REALLY BAD. right?
So I've been testing CM9 for quite a while now and can't help notice the battery life has been reduced heavily compared to Honeycomb 3.x.
Now, I don't mind that my battery life gets a bit shorter as ICS brings more features and might be more power hungry. But I went from my tab being able to hold a charge in standby mode in 3 weeks to barely 3 days. And if I use it more heavily, it barely holds a day, which is worse than my Motorola Atrix and that's just not normal.
Now, I've been discussing this with pershoot and for him it must coming from something I do. Honestly I don't see what. In the Honeycomb days, I used to have so many apps installed (may 100-150) and battery life was fine. In CM9, I'm running 50 apps, the essential ones. All the apps that could be power hungry have those settings set to off. No push notifications, very large updates intervals (a day) or none when possible. Also, I run most on these apps on my Atrix (which has more apps installed) and my battery life is way better on the Atrix.
In usage itself, I don't see any change, it seems the tab consumes the same amount of battery than before. It's the sleeping battery life that is terrible. In my case, in sleep mode, wifi is off, brightness is set to Auto and data is off (not the signal itself but I tried to take off the SIM and the battery life is the same).
Honestly, not having to care about charging every day is a must feature for a tablet.
I'm running now RS125 ICS, based on stock and the issue is also there. So I wouldn't say it's something related to CM9 but more on how ICS behaves with our tab.
I've read report of other people complaining (with the 10.1 also) so I wonder if it's a general issue. Could you please fill the poll so we can see if there's an issue and if so, how could we identify it ?
Don't hesitate to describe your tab usage and battery life !
Thanks !
For me worsts battery life was with the official 3.0.1. 3.1 was big improvement. 3.2 and 4.x were a little bit better than 3.1.
Got gmail and exchange push notifications turned on, but most of the time the tab is connected to the wi-fi, not to the 3G network
Attached is my personal stand-by record on the 10.1v. I think it was with one of the first pershoot's CM9 roms
Hi Danny,
Same for me. Especially the standby mode I see a battery drain.
By the way, somehow my battery usage is not working since I moved to the official ICS ...
Cheers
No problem @all. Stock 4.0.4 with OC kernel.. Looks like this:
