[Q] Cyanogenmod 7.1 Battery Life?

Hello all,
I have seen reports that because the source code for the captivate has not been fully released, some of the processes cannot be put to sleep when they are not being used, and therefore causes bad battery life. I am just about to flash CM 7.1 and am curious to know how the battery life is on the captivate.
All info is greatly appreciated!

LWt mw know what you find out! Just flashed it and my battery goes quicker than my bank account. Please let me know what I can do to help this I like the rom

Jaye,
This happens frequently when flashing a new ROM, you should try wiping the battery stats or giving the ROM a few days to calibrate with the battery.

Been a week for me and battery life is still horrible. I lose about 25% an hour

You should try a custom kernel like glitch or Neo to see if that will help. I get awesome battery life in miui which is bases of cm7. I find that neo gives me the best battery life.

What do you think about the Boog Kernel?

Also, some people must be getting solid battery life, or CM7 wouldn't be as popular as it is. Or is this a known thing with CM7?

I get better battery life on miui and neo kernel than any samsung rom I have tried. But each phone is different.

Yeah that's pretty awful. Try doing a battery calibration to see if that helps. It should never go that quick (unless you're playing some serious games). I've never really had great battery life with cm7/miui I've had the best battery life with all the recent samsung gingerbread leaks. I think those are better than cm7. But that's my opinion.

I am in CM7.1 since Sunday. I had very awful battery in start. So I did battery calibration, manually. So I got very decent battery on wifi. But at work I use att data so again my battery life was horrible. But I am seeing improvement since I am using this app called green power to manage my data. Try that.

If you get good battery on WiFi but not with mobile data, try a different modem. Not only are some modems inherently better on battery, but if you find one that gives you a better signal you should see improvements in battery life as well.

Flashing the Glitch kernel seems to have improved my battery life.

Hi, Can you point me to a post that (a) has the Neo Kernel and (b) explains how to flash it on MIUI? I've had MIUI for a couple of months now and battery is to as good as expected. Would love to try to use another Kernel but I sincerely don't know how to do it.
Thanks in advance,
Mauricio

I just love MIUI, no battery problems for me. Gets me through 2 days of moderate usage so I'm a happy camper.
I just wish it had the Audience chip workingg...

Solid Battery Life w/ Stock Kernel
Hey Everyone,
Juts came to report that I have been getting great battery life using the stock kernel. I would say it is a little better than Serendipty VII Build 2 which I came from. Only issue, and this is something I know is inherently wrong with Cyanogenmod on the Captivate, when you fully charge the device, it only shows it is charged to 98%.
Other than that, all good!

Have you seen an improvement in this regards, I am having the same issues, the WiFi is draining my battery slower then my data is.
I have also done the battery calibration and it doesn't seem AS bad... still doesn't appear to be great though.

I am just coming back to this ROM after experiencing battery issues even though Glitch helped a little. I decided to try and tweak some more this go round.
I am experiencing much better results this time. Here are settings and other tweaks or modifications I have in place.
-sync is turned off
-using Launcher Pro with very few widgets (just 3GWatchdog and Power Control)
-auto brightness turn off manually adjust according to need
-gps, wifi, BT, and data turned off when not in use
-wifi notification and location detect off
-installed jk4 modem (may get better results with different modem depending on your area)
-installed Glitch v12 high leakage
-the biggest factor this time I think is UVing on the Freqs that are used while phone sleeps >>>>>100/200mhz (set for the lowest UV setting possible on these that do not result in a sleep death or reboot when phone is put to sleep)

[Q] Increase battery performance on Optimus x2

What is the best way to increase battery life on LG P999 Optimus X2?
Model: LG-P999 (Wind Mobile Canada)
OS: 2.2.2
Baseband: M6600A-SCAUTNZ-2.0.9.972T 1
[JUL 15 2011 10:00:00]
MP:TRULGLE_08.09.02R_MDM
Kernel: 2.6.32.9
Build: FRG83G
Software: LG-P999-AWC-V11h
Rooted: YES
Or would it better to put on a custom ROM instead that looks identical to the current stock?
I am not sure if this battery issue maybe due to the fact that I had O2X installed and then flashed it back to a backup copy I got from XDA-Dev but ones again not sure, it just seems battery now die's even faster then it used to with STOCK firmware without CM7 and O2X

Isnt that a g2x
http://forum.xda-developers.com/forumdisplay.php?f=1114
Otherwise I am happy with battery performance on Miui 1.11.25

I don't think so since its 2x is also P-999 unless it P-900. I heard Miui lacks some features and has problems dealing with stuff like MMS and others.
Would still love to reduce battery usage

Your phone is a g2x as its real name p999 proves it. Canadian providers falsely renamed it o2x.
O2x is p990. Nobody had the unique solution for battery. Too many factors.
As hardware, kernels and ROM are different, you should ask on g2x threads.

LG optimus X2 (P990) battery charging
Hey guys I bought my LG OX2 a month ago, and I do have a few phone/tablet chargers, one for my blackberry, one for the kindle fire and one for my LG-OX2. All of them have the same connection, so I thought i will keep my Lg charger at my office and use my kindle charger to charged my OX2 at home. I was using CM7 and i had no problems at all. A few days ago I flash it with NOVA HD+ and first couple days charging over night with the kindle charger had no problems but after that in the mornings my phone is completely shut off. So i have to take the battery off and back on to start it. This morning i notice it again but the battery was empty, so i connected again and after 20 min was doing fine but after 40 min the phone shut off again completely and was very very hot specially where the camere area is. Anyone knows if is because I'm not using the original charger or is the new rom NOVA HD+.
Any suggestions?
Thanks!

It shouldn't be the charger. All micro USB ports should have +5V on their power terminals (this is the USB voltage from your PC USB port).
EDIT: You can refer to this link
http://en.wikipedia.org/wiki/Usb#Power
EDIT number 2:
Unless, of course, your charger is defective.

Well yes you're right is not the charger. As i just connected to the lg charger and after 15 minutes i check the phone and was very hot and unable to turn it on. So I had taken the battery out to cool it off for a few minutes. What else could it be? I don't remember or changing or doing any tweaks.

I've seen a lot of complaining about exactly the same thing as you. I would try flashing temasek's latest kang and vadonka's latest kernel, which should be among the most stable ROM/kernel combination out there for O2X.
If you still get SOD (sleep of death) while charging the phone, it could be a defective battery, or a defective phone altogether. In which case I would suggest that you try to flash your phone back to factory settings and ask for a replacement.

I appreciate your input. At this moment is charging ok, no heating, no SOD (SOD hehehe funny). I have download it the latest NOVA HD+ and i think i gonna give it another try. If continues heating up while charging I will take your advice (although flashing temasek's latest kang and vadonka's latest kernel sounds more complex work for a newbie like me. Do you know if there's any tutorial to follow?)
I will post the result after the update.

It's very simple. How do you flash NOVA? Isn't it through CWM? Flashing temasek's kang and vadonka's kernel is exactly through the same method.

The first time I flash NOVA was thru rom manager. Last night i flash the latest NOVA (which seems to be a new version almost everyday) http://hei1125.hopto.org/Nova HD (CM9)/
And I did it thru recovery mode, this time I wiped cache and delvik. And seems like everything is working normal. I did charge it over night, no heating, no SOD, is working flawless. Camera, clock, email working fine, browser now works on landscape which before wasn't. Video still not working. (ooopsss as i'm testing the video the phone kinda crashed and i had to remove battery to reboot it).
But so far so good... I hope stays 'stable'.

Glad it's working better for you now
How do you test the video? I can record video and play it back without any problems. I can also play youtube videos. Never had problems.

I open muy camera app and click on record video and the apps shuts down with a message "sorry the camera was closed because of error".
I can play videos on YouTube without problem.
So for a couple times the phone has gone frozen and the only way to reboot its by removing the battery.

I have found the solution to the poor battery life on the wind mobile G2X.
The culprit is the stock battery. Get rid of it. I was getting less than 3-4 hours battery life from mine with everything I could possibly do to reduce the battery load.
I purchased an extended battery off e-bay. It is the identical physical size, but has 1950mAh.
I now get well over 24 hours battery life. Over 10 hours playing games/browsing internet.

A lot of discussions about aftermarket batteries in many forums (here i guess, too).
If there is a print on the battery like 2200mAh, actually it doenst mean anything. You can be lucky to get a higher capacity or maybe get one with less. Dont believe in the sellers claim

battery performance
in the market you will find same aplications like battery maintenance-very good for battery life

[Q] Best ROM/kernel combo best battery life w/3G is turned on (Android 4.0 & above)
Hi guys, as per thread title -
I'm constantly on the move and usually do not have access to a charger for the day, and I rely heavily on 3G for my job. I don't wish to go back to stock Gingerbread, and will at be on Android 4.0 and above. 3G seems to drain a lot of battery.
Be it flashing customer kernel or going to the extreme tweaks, do share your thoughts here! V30J was a good ICS rom with acceptable battery drain, but it has its own set of issues (mainly freezing randomly and not waking up). But that's my benchmark of battery life, as I got almost 10 hours with moderate usage (no wifi, no GPS, minimum brightness etc with Pimp My Rom).

Since your a local, I bet or kiasu(Singapore Attitude). Or maybe not. Anyways, The best for battery life is V30J. Or not. When I used it, its very power savvy. But take note that the performance is poor

yeah perhaps haha but for one I don't mind a sacrifice in performance as long as the rom functions and doesn't drain battery. However V30J as mentioned had its freeze issue and that is a problem that I may not be able to accept.

Battery drops!

Well, this is weird, I bought recently a i9000b guys, my old Galaxy Ace rusts in peace now... well, flashed it (took some long hours) and now i'm using CyanogenMod 10, but here's the probelm
It has been charging the entire night, then this morning I took it and went to take a breakfast, I've been chatting and stuff but it got laggy, so I decided to restart it (apparently with 72% of battery aprox), when i checked it again after the restart I saw 4% of battery. What? Is that possible? I must say that I haven't calibrated the battery, I tried to check if charging it with the phone off and had a very low battery level. What could it be? Battery Calibration? Rom? Kernel?
ROM: [ROM][LINARO][JDQ39E][22/05] **C-RoM Mix v22 *&* C-RoM v3** [ Stable & Fast... ] [
Kernel: Semaphore 2.9.0 (for i9000b)
Thanks
PS: I turned on again the phone and there was a 80%~ of battery

Do one thing might solve:
Switch off your phone
Rwmove battery
Press power button for 15-30 sec
Insert battery back and reboot
Let me know if it solves your issue

Done, let's see if doesn't happen again. Anyway, should I wipe the battery stats? I haven't yet...
I will be doing tests because it happened to me yesterday, I got a random shutdown and the battery was empty, so I'll be looking for that.
Any another solution is welcome, thanks anyway :good:

Battery drain problems are usually kernel related, yeah. When I tried CM10.1 I noticed a hell of a lot of battery drain as well (then again, 3 year old 1500mAh battery, 3 year old SGS, can't expect miracles).
Try using any of the 4.2 kernels in the forums (Semaphore, Mackay, Devil, CyanCore). I've tried most of them (usually Semaphore) and they're all pretty good for getting that extra bit out.
Aonther option would be to switch rom. Some devs have made roms with pretty good battery life considering the extra ram consumption on JB.

Thanks, i'm on it, will change my rom to Mackay rom and kernel, sadly this kernels aren't usually updated, because I have a i9000b and there are not much kernels for this model. I'm going to install a Mackay kernel compiled for i9000b

[Q] Battery life

I've tried a few ROMs, including Albinoman's CM11 (4/24 official and a few nightlies) CM10.2 (the newest October official, I forget the date ). So here's my question: Out of all the JB+ ROMs out there, which ones have you had the best experience with, in regards to battery life? Right now I'm running Albinoman's CM10.2.
Also, any battery life tips would be appreciated. Currently, I am doing the following:
LCD brightness turned down
LCD off when not in use
Wifi/GPS off when not in use
Processor slightly underclocked
Unnecessary/unused apps removed/disabled/stopped
Haptic feedback off

In all honesty, I think my best battery life ROM has to be albinoman's CM 11.

I have to agree with Isaac. I'm running the 5/15 nightly and my battery life has almost doubled with BT and GPS turned on. I just turned BT off and set location to "battery save" so I'm hoping to squeeze even more out of it.
Don't get too excited about my doubled claim. Prior to CM11 I was running Paranoid Android (Jellybean I believe) as my daily driver and would get about 6 hours of battery life on standby. With CM 11 I get around 11 hours with light use, the Vivid is just abysmal when it comes to batteries.
Now that MMS is working the only complaint I have is with the in call mute feature not functioning, but I can live without that for now. I plan on running CM11 as my daily driver for the foreseeable future.

Ain't that the truth. I'm sporting a 3500mAH extended battery and I get like 12 hours with light use. Can't wait until I can afford to upgrade and put the Vivid on a permanent leash. Maybe make a media server out of it.

Well I stand corrected. I'm still running the Albinoman 5/15 nightly (loving it) and over the weekend I conditioned the battery by running it dead and then overcharging it while it was turned off. I now get 24 hours on light usage and about 10 hours on heavy usage. I had tried this process on other builds and versions but this is the first time it's actually worked. The battery I'm using is the battery that came with the phone. I'm amazed!

Don't unplug it or turn it on once the charge indicator turns from orange to green. Keep it plugged in and offline for another 2-3 hours.
