CM7 Battery Solution?

This is NOT a thread where I have a fix for battery usage problems on CM7; I'm looking for a fix. Ladios's kernel is not fixing my battery issues. I'm running Ladios's modded RC4. It's not that I get battery drain while off; while actually using the phone's internet browser/doing anything other than texting it'll drain at faster than 1% per minute while browsing in 3G. Putting it in Edge is NOT an option, I did not buy a 2G phone. Any solutions?

Why start a new thread just to continue your constant pissing and moaning?

You don't want to admit the battery life is a joke? If it wasn't for S2E I'd probably flash over to Sense.

Zing!

My point was that there are more than enough CM7 threads to post in, and you choose to start a new one. After complaining in all the other ones too.

My battery is fine. Maybe layoff the phone and stop making pointless whining threads and you wouldn't drain so much.

Here's the thing man. Cm7 has new features etc that take up more processing power which = battery power if u trace what is actually being used.. common sense. Sure cm6 may have outstanding battery life we all know that. However, It may seem small but did cm6 have the notification pull down Widgets? The theme Chooser app? Compcache support, nicer graphics? All of this plays a role. The more features were ***** and moan about NOT having leads to *****ing and moaning when we do have it. Add in the tweaking and time spent testing new releases and yea our battery will **** out. If we ran stock full time no Modding our battery's would run to manufactures spec minus a few lemons here and there that get missed by the phone company production line. Nothings perfect. But honestly give the battery a break. Just cause software is updated doesn't mean the battery magically can handle it. Hate the battery life? Get a new battery or a new phone.

a) this is the first thread I've made
b) by *****ing, posting issues in the nightly topic, I assume
c) early builds of cm7 battery life was great
d) cm6 had the pulldown power widgets
Since when is 5 hours of battery life usable?

[Q] 3G Huge Battery Drain

I'm experiencing a HUGE battery drain when i'm over 3G Network.
I'm using inDroid v6 Rom + G3 Kernel Ultimate (Not overclocking all the time ofc,i'm using "on Demand" ).
Any idea of whats happening ?
Would a Factory Reset Solve it ?
I've tried Battery Calibration app,twice,and still getting drained.
Maybe,chaning the kernel should help ?
I just dont know, waiting for a Light !
Many Thanks in advance

I'm getting 1.75 days on a single charge . No 3g usage but wifi with moderate gaming and calls and stuff.
Havent changed the fugumod kernel that came with i6.
better replace g3mod by fugumod from OTA. I hope it'll solve ur prob.
I'm not an expert , just based on my experience

My battery only gets drained once i'm using 3G.
Overall lifetime is preety decent considering gamming + heavy usage.
I recalibrated the battery (for the third time),and so far,it is working.
Lets hope / wait !
Thanks anyways : )

whether battery calibration has to be done with 100% charge or not?? and after calibration what does it mean by full cycle? discharging it until it switches off??

Same here :-(

Try another kernel
I use g3mod v2.0 (waiting for 2.1 final version), but you can try Fugumod, and see whats bets for you

First charge phone fully to 100% Leave it for maybe an hour extra because the phone shows 100% when it's actually maybe 95% ish. Then calibrate the battery and fully drain the battery until phone dies. Then fully charge. Then fully drain. Do this at least 3-4 times and your battery should last a little longer.

by now I've seen quite a lot of reports about heavy drain in 3G.
not sure if this is entirely exclusive to g3mod but might be.
I myself am tinkering much with my device right now to know what causes what.
Can anyone tell whether 3g drain is also a problem in fugumod?
Perhaps some kind of bad setting that causes excessive polling?

There is no such problem in fugumod from what i have seen. Also tinkering with your device without having a lot of knowledge about how it works could cause problems. I should know

I know just about enough to keep it running, toy around the Linux level with busybox, change mount options, locations and the likes while also frequently changing the kernel to g3mod's latest.
It's really hard to know whether you get a comparable objective reading of the battery capacity, even after recalibrating.
Sometimes when I'm outside my battery drops relatively quickly but then back home it remains at the same percentage for hours. So I guess the quick drop was a false reading.
It might also be temperature related. Or about local 3G infrastructure. Or something to do with your custom ROM and installed apps.
That's not to say that the 3G suspicion is invalid though.
But do fugumod / g3mod even address the 3G module with different drivers?

G3MOD is HEAVILY modded so i think they will have messed around with the 3G module. Fugumod is a little lest intense so i don't think as much development has been done to it. Just the basics which is why i love it.

battery drain is dependent on rom too.some heavily baked roms will give less battery life

[Q] Odd battery spikes adding to battery hell

I've been having general horrible battery problems with my Sensation on stock Sense and Miui.us. I just installed HyperSensation and Faux 0.2.3 kernel with a full wipe and reset the battery calibration thinger.
First 2 charge/drain cycles were yesterday (got around 5.5 hours as has been normal for the last 2 weeks) and after the second drain to 1% I plugged in AC and went to bed. This morning I checked Battery Monitor (not the Beta or paid, so I'm aware the mA reading may be incorrect/offset on Sensation).
The graph overnight shows some odd spikes every 50 minutes draining the battery. This is the first night I've been looking at my graphs so I'm not sure if this is regular or a separate issue from my normal battery hell.
I've included a screenshot of everything I could think of including Battery Monitor and SetCPU profiles. Re running apps, some I've never run before, the only other one on the 2nd page was Thumb Keyboard.
I would really appreciate some ideas on my battery life in general, and what this issue is in particular.
Background:
- Horrible battery problems with my Sensation on stock Sense, Miui.us and now with HyperSensation ROM-CM7.1 with kernel faux123v0.2.3r.
- Been getting around 5-6 hours with normal use, no 3G, no wifi, no GPS, no Bluetooth, low screen brightness, etc etc.
- I also uninstalled Gallery as I was getting the sensor usage issue which I thought may be causing my battery woes, but no dice yet.
- I prefer to keep data on at all times (2G) as that's what I use my phone for, so I don't use this Juice Defender function.
Thanks,
P7

How did you calibrate your battery? Did you..
Flash Rom
Kill battery to 0%
Charge fully 100% then wipe battery stats? Or did you wipe battery stats as you flashed? Thy could be a major problem
Also you have CPU your max set to 1.56ghz when its charged. That could cause the peak in usage. Especially if you have it set to performance and not ondemand. Those are the only two things that's really stand out to me.
Also check the arhd thread. In one of the last pages (depending on when you get this) there is a link for a fix on battery drain on fauxs latest kernel. Check it out

Thanks rddocke, I will check out the kernel fix. I did wipe, flash rom and reset the battery stats at the same time. I will definitely try your method, I didn't realise I had it upside-down.
As for the spikes, they seem to be continuing today, I can post screenshots later. Given that the major battery user is "Adnroid System", would this narrow my issue down to the built in apps?
On the plus side, with the new setup today on my 3rd battery cycle, I am getting better battery life than before aside from the spikes.

ya the spikes could be do to an auto update, maybe background sync... any things could cause it as long as it isnt a constant high usage i wouldnt worry about it. but if you want to help your situation i would set back my cpu max to 19200 when charging, and clock back to 1.2 for daily use, switch your goveners to ondemand and get them off performance.
basically whatever its doing at those times its running at the highest point your cpu can handle. adjusting wont solve your problem but it will reduce the amount of battery it uses
idk its hard to tell android system is always going to be the juicer, that and sense. nonsense for arhd could help you out too. i particularly like sense tho
hope i helped

I'll change these settings as well, great. I feel like I'm getting somewhere gradually, been spinning my wheels for a week on this.
I can't 'thank' you for some reason, but my buddy should have just done it, which is fair since I can finally pester him less about my battery problems and pester other XDA members instead!

No problem buddy glad I could give you some help. Let me know what you discover from all that. Another tip I could give is maybe test out a bricked kernel 1.4rs or 0.91 seem to be working best with sense 3.0 from what I've read

Android OS killing ICS batt life?

So, one thing I've noticed when running through the various ICS ROMs and kernels is that regardless of rom or kernel, Android OS eats up battery at an alarming rate.
In my experience, it usually is eating more power than the screen, which just aint right. Now, I know these ROMs are at an early stage, but this is a common thing between all of them. I've noticed a few others noting it, but I think most are too excited about the new OS to notice the batt life.
Has anyone narrowed down what's going on? I'm curious....
**NOTICE TO FLAMERS**: This is not a post passing judgment on ICS. I'm simply asking if anyone's figured out what the issue is currently, or if anyone has solved it.

Don't form an opinion of ICS until you actually run an official rom, and not something someone hacked together from AOSP release from a different phone, and leaked dev binaries.
I see this happen too, on the rom i am running. but won't form an opinion until there are proper roms out.

my battery life is great. I get 15+ hours on mine with no issues at all.

There was no need for that....

it doesnt necessarily mean that the android os is using more battery. you can also look at it a different way.. maybe the screen is taking less battery. if the android os uses the same amount of power as always, but the screen uses less, the % battery used is going to go up for android os.

Yeah, but the likelihood of a hardware item suddenly using less power than it used to is certainly way less likely than an OS, software-level item.
I understand your theory on percentages, but as I'm sure you've noticed simms, something's draining the batt quickly, even on UV kernels, and I'm willing to bet it's OS related, and probably related to Android OS (in batt usage). I doubt this is the type of batt life we can expect with the official OTA, so I'm thinking something's running amuck.
My screen used 26%, while Android OS used 39%. In the past w/GB roms, it would have been more like screen 45%, Android OS 11-15%.

im just playing devils advocate, to try and see it from a different point of view. right now my screen is at 43% and android os is at 35%. normally my screen is around 51-57% and android os is around 7-11%. mind you, i am tethering at the moment also. but, the screen % is below what it normally is and the android os is much higher than it usually is. so something is definitely going on.
btw, in on the seuv kernel, and its doing alright on battery for me.

i am usingkoush v11 with Franco 26/11 kernel. Off charge at 9.30 am at 98%...5.30 pm 89%...very little usage today..just a couple of emails..but easily getting 15+ hours of battery life with WiFi my main usage including phone calls over WiFi.

My phone is turned on for 17 hours 38 minutes and still has 24% battery with brainmaster v5 + franco kernel

I've noticed this, too.
Last BM version drained my battery massively over night while being in flight mode.
Android OS took 87% of the battery in 8 hours.
So it's definitely a bug.
CM9 Alpha 11 is way better. In 18h 36m Android os 25%, android system 17% Display 15%.

Even though i appreciate the work the devs who are coming up with these ICS roms are doing, i can't use any of them as daily drivers (no flash/Google calender sync issues/performance is noticeably slow e.t.c). Played with Koush's version the other day and was mighty impressed, very. I'm still not sold on the whole ICS look in general, might take a while to get used to it. Seems too fluffy to me, too much eye candy. Battery life wasn't the best, but manageable.
Right now i'm on Oxygen+Carbon rom mix with Franco kernel, and OMG this combo is phenomenal regarding performance and battery life..

my battery life is the same, if not a tad better.. using kwiboos v2.

With all due respect, "Don't form an opinion of ICS until you actually run an official rom " is not a statement of fact, it is your opinion/emotional response based upon you misunderstanding of my post. I clearly acknowledged that we were working with early builds, so this is obviously not what the final product should be.
The purpose of this general forum is to have general discussions, and troubleshooting posts. I made a troubleshooting post, seeking out others experiencing the same thing, in an attempt to solve the issue, or see if the culprit has been found.
I will admit that I overreacted a bit, but I think you did the same.
I'm gonna leave it at that, otherwise this'll turn into a flame war.

I'm curious: check your batt usage. Do you see Android OS almost equal, if not higher in batt usage than the screen?
Now remember, on phones, the screen is the biggest power drain for anyone other than a light user (never turns on screen, makes 1 call a day, etc). Typically, in my usage (usually 25-30% brightness), the screen takes anywhere from 40-50% of my batt life thru the day, with Android OS way down the list. That was Gingerbread.

Android OS 38%
Display 29% (brightness at 12%)
Miren Browser 17%
Cell Standby 9%
74% remaining
8hrs 44min on battery
Sorry, my native screen cap won't save to disk, otherwise I'd upload it.

Yeah, I figured it'd be way up there. Now, I'm not saying batt life is BAD. I still can get a good 15-20h out of it if I dont use it much. But I'm used to going 24-36 hrs without having to charge, all with medium usage. I've tried various UV kernels to achieve this again, but Android OS is dominating the battery.

My battery is actually good. I am on cm9 alpha 11 on franciscofranco's kernel. It lasted more than 24 hours on medium use.
more than 24 hours is already good for a smartphone.

yep. My first impressions for it were the same, too much eye candy and too much things going on the screen. Maybe I was just used to the very simple and minimalistic UI of the stock gingerbread. But after using it for a day.I am beginning to realize how amazing and beautiful ICS is.

Yes Android OS is top for me at 45% and on GB ROM it was 4-5%. Batt life ain't too bad but I think the Android OS usage is just something that will get sorted as the development moves forward, especially after the official update drops.

Battery Life on Infuse: Gingerbread vs Ice Cream Sandwich

Hi, so I recently got an Infuse from someone that is still on Froyo and I figure I might as well upgrade to a custom rom.
Since I care about battery life the most, I figure I would ask which version of Android provides the best battery life for the Samsung Infuse: Gingerbread or Ice Cream Sandwich.
I probably won't be running apps that fetch/push for data a whole lot, which obviously helps the battery life. But I thought I'd ask to get someone's opinion on this specific phone and a comparison between Gingerbread vs ICS before picking a rom.

And the winner is... Gingerbread!

Gingerbread is a better battery saver. Although i get decent battery on ics and jellybean. I know i perfer all that ics/jb has to offer in features over having battery life. But for what your asking id suggest AEON or the stock gb. Aeon is very stable and has some cool extras without much battery drain

Really? I got faaar better battery life on Scott's Paranoid Android ICS build than I EVER did for any Gingerbread rom...

Honestly, I don't even remember by now
I have never payed that much attention to battery life..
usually lasts all day for me on JB, that's all I need
Sent from my sweet & buttery Infuse

the more recent ics and jelly bean kernels get great battery life due to fixed bt and wifi drivers (the wifi driver and binary were taken from another device from what i understand) and more stable cpu clock code than it had initially. not too much more than stock but i have to say it is better for me. but i guess it all depends on usage. one may have better standby vs awake battery life or something. the available kernels have been this way for atleast a month. when we start to see more kernels with undervolt it should get better yet.

I'm using CM10 8/23 and my battery life is good.
One of the best I even made a snapshot (can't upload right now): 51% left after 12 hours 46 minutes.

That's why I'm in a dilemma between jelly bean and gingerbread. I do appreciate JB a lot, way better functions. But still the battery life and compatibility are big issues. I can get 2 days under gb but only less than 12 hours in JB, that's a big issue.

I have been getting great battery life with the latest JB ROMs I have been using. Pretty much on par with the GB ROMs I used.
Sent from my SGH-I997 using xda app-developers app

Can't say i've had good luck with battery life, I used to average 3 hours of screen on time in Gingerbread, but since moving to ics/jb that has dropped to anywhere from 30 mins (if i leave the phone and standby drain eats it) to 1 hour 45 mins on a single charge...not good.
No rogue apps, no media scanner (i constantly check these things with betterbatterystats, i don't install anything i didn't install on gingerbread). Just the cell phone standby drain eating my battery alive (BBS reports it as GTALK_ASYNC and RILJ wakelocks).
I've been researching it for months now and get various answers (the wakelocks are caused by bad APN settings for example), tried all the fixes, still no luck. I suspect that it's probably a Rogers thing but who knows.

you may consider a factory reset and sdcard format
when you reinstall, decline all google locations and backup services.

I have done a factory reset, i formatted my sd card not too long ago (I also suspected this)
I also make sure google locations is disabled, never keep backup enabled (i did once by mistake and the auto restore nearly killed all my monthly data)
I am going to toggle wifi tonight and set a marker in BBS, i'll check the drain overnight (I did this a while ago and it did improve standby drain somewhat, but I am going to try it again)

Can't say i've had good luck with battery life, I used to average 3 hours of screen on time in Gingerbread, but since moving to ics/jb that has dropped to anywhere from 30 mins (if i leave the phone and standby drain eats it) to 1 hour 45 mins on a single charge...not good.
No rogue apps, no media scanner (i constantly check these things with betterbatterystats, i don't install anything i didn't install on gingerbread). Just the cell phone standby drain eating my battery alive (BBS reports it as GTALK_ASYNC and RILJ wakelocks).
I've been researching it for months now and get various answers (the wakelocks are caused by bad APN settings for example), tried all the fixes, still no luck. I suspect that it's probably a Rogers thing but who knows.

i do notice battery drain in some areas. but not others. some people seem to think certain modems are effecting the cell standby drain, not sure myself. but there are many compatible modem.bins to try from att and t-mobile(t959v)

Just an update: wifi didn't help much.

I've been playing around a bit with different gb kernels, odex and deodex.
I found the drain issue much less on stock uclb3 kernel and rfs file system.
Almost all drain were associated with being on wifi...wakelocks and something else kills the battery.
If I have wifi off, there is usually not any issue.
You may have to play around a bit to see. My experience on cm9 and cm10 has been limited. I have noted several users noticing drain on cm9 and cm10 as well.
To avoid drain:
1. Use it to the max and constantly.
2. Leave the phone on airplane mode when not in use.
3. Turn off data (wifi and mobile data) and background data when not in use. I use this last mode.

Thanks for the tips man :good:
Airplane mode of course makes batt life better (disabling data doesn't), but when I start having to make sacrifices I didn't have to on GB it becomes a problem for me. Why should I jump through hoops and gimp my convenience for battery life that still isn't even as good as GB?
Instead of that i'd rather try to find the root cause of the problem. Doing so then allows us to help others that may have the same problem.
It definitely is an issue with the radio (or rather CM code overlooking something concerning the radio). What exactly, i'm not too sure. I've tried different modems as well, UCLB3 on JB was awful for battery life, UCKL2 and UXKG3 are slightly better but still not that great.
I don't want to complain about these things, I always try to research first, but damn....i'm stumped.

Yeah, I agree with you there. The techniques I use is pretty simple. Pose the hypothesis. Start with a full deck and slowly eliminate or start minimal and add.
ex: flash jb without gapps; without microSd. try different modem; try a different kernel. different kernel from different build.
have to use it for a few days to find out.
do the same for cm9.
add gapps...
add microsd
etc..
at some point, you will find out contributing factors.
There are a few battery thread that may be helpful if you havent looked:

Really? I got faaar better battery life on Scott's Paranoid Android ICS build than I EVER did for any Gingerbread rom...

This is true, and you can save battery life w/ customization and now Scott is up to JB being one of the best battery life roms I've run
or just turn down your screen brightness
