CM5 or CM6 Battery Life ?

Which provides more battery life.
Im on CM5 now and my battery dies SO FAST you can almost see it going down just watching the screen, i have the screen turned all the way down, use only 2g networks. ever tried to under-clock, when i check battery usage says system idle uses 49%
any ideas ?

Are you serious?
Better yet, don't use the phone at all, that might save the battery.
Dude with those settings its like having a 20th Century device.
Flash another ROM or something, try wiping battery stats, it has been suggested all over the forum...
Why do I even bother...when the mods see this youre a gonner anyway.

It's not so much the ROM, its the apps and widgets you have installed. Some are poorly written, some don't play nice with other apps or certain set ups.
All you can do is install a monitoring app like system panel, and remove the apps that are using alot of CPU.
That's what I have done.

listen pal what im saying is my battery doesnt last for **** since i flased CM5 so im wondering if thats to be expected with CM5 and maybe fixed in CM6. but yea ur super helping that for the sarcastic reply, next time dont bother. ooh and btw i dont have to use the phone for it to die with in like 10 hours it will be idle the entire time and it will die.
Edit : OH LOOKY (Dev)CM's2.6.34.2(NR-6.35)(v0.63_08/16)(git updated-08/16)
**ONLY FOR NEW RADIO MAGIC-6.35**
Updated comp to 2.6.34.2 code, mic works, power issue is gone
look a possible fix with CM6...smart ass

and thank you for your helpful reply i will look into the apps i have.
EDIT: Battery usage says system idle is nearly 50% of usage, even after i kill all the apps :[

LOL! Wow, someone's a little edgy...
It's definitely not a "CM5 issue" that would be fixed in CM6 (CM6 is still in RC, CM5 has had several stable releases!) eyegor's suggestion to wipe battery stats was probably good advice believe it or not. Charge full, power off, leave plugged in. Boot into recovery and wipe battery stats. Power down, unplug and start up, let it drain allllll the way.
Check out xda homepage even - a battery calibration post!!

Battery life is pretty variable as you can see in the numerous threads on this topic. CM's forum has one with a poll with most saying CM6 is better, but not a clear cut answer.
I used SystemPanel's monitor function to identify which app was eating battery. It worked great! My biggest offender was Weather and Toggle widget. I loved its customization but its battery gulping was just not worth it. Got rid of it and my battery life is much more consistent.
I also got a cheapie battery off eBay which helped.

Both CM5 and 6 run perfect on my phone. No battery drains.
My point was that you're in the wrong section, pal.

You also might want to watch logcat while the phone is idle or sleeping to see if there are numerous errors or warnings scrolling by when there should be very little activity.

I have a similar issue. Initially I had the rediculous drain, but as mentioned wiping battery stats from recovery fixed it for the most part. Once it says its fully charged and you turn the phone off, let it sit charging overnight. Then wipe the stats in the morning and don't charge again until the phone turns itself off. Only issue I have now is that when I've got my GPS turned on, in use or not, it kills the battery. While in use I get about 2 hours from a full battery to the phone turning itself off. Haven't figured that one out.

thus far ur method has worked ! my battery so far seems to last longer then when i first got the phone LOL
i was playing music at the loudest volume for an our just to test it and it only went down 3 percent battery life
thanks man

No worries. It freaked me out when I first flashed 5.0.8. I use my phone as an MP3 player in my truck with it plugged in to my CD players AUX Jack. Did a 5 hour road trip and only lost around 10% including a few phone calls.

[Attn] battery life tips

As I've noticed people ate flooding the threads with battery issues
I thought some tips might help
1. Wipe battery stats once and only doing it when switching between liberated and cm6, don't do it everytime u flash over a newer version of the rom
2. Use minimal brightness and do not use auto, although it may seem like it helps it doesn't, someone told me this and explained basically using the sensor wastes more batter than it saves
3. Use minimal data and get into the habit of shutting it off right after your done or set it on 2g for those who need the notifications, yes it might take a few seconds more to download but its better than the phone being dead
4. Don't let the phone completely die its bad for the battery, I've got into the habit to charge it every night even if it is full and its shown improvement
5. Leave the thing alone!!! If you need the phone don't play games, or anything else that drains it

To contribute: Lithium batteries are most definitely temperature sensitive. When possible, take it out of your pocket, bag, etc. The hotter it is, the more it drains.

4. Don't let the phone completely die its bad for the battery, I've got into the habit to charge it every night even if it is full and its shown improvement.
^ that is a very important thing as Lithium Ion batteries do not react well to being deep cycled. It is actually recommended that you charge at no less than 35% to prevent the battery " memory" from retaining half charge and reporting full. Almost all new lithium ion batteries are manufactured with a microchip attached to a PCB. This maintains battery function and also allows your phone to report what the current charge, temp, and health of your battery is.

How do we set Aria to 2g ? I want to turn off 3G however not finding any option. Battery life is terrible with Aria.

if you are on stock/liberated use the dialer to put in *#*#4636#*#* (speed is neccesary)>>phone info>>prefered newtwork type>>gsm only
cm6 has a toggle in the network settings/power manager

I've seen a couple posts, in other forums, that a task killer will hurt battery life more than improve it. Is this true? If so, why?
Also, I wiped battery stats more than I should've. Did that do permanent damage or will it fix itself over time?

some programs you cant kill so it makes the cpu jump to 100% which drains the battery
i personally find out which programs pop back up and put them on a ignore list to make it drain less
it isnt permanent it will fix over time just charge it fully and dont let it go past 15% and it should improve over time

If your in a 3g saturated area the 3g will contantly swap towers even with screen off, when i first got my phone i could sit and watch the battery level drop about 1% every 10 seconds to get around this open phones dialer and dial *#*#4636#*#* and under phone status select gsm only you use same method to swap back to WCDMA prefered for 3g if you need to use wifi tether or need high speed but this was like a whole new phone for me battery wise. will be neet if there is an app that enables 3g for like browser or maps or something like that and then swapps back to edge when not using something that would need it. if there is already one out there lemme know i could use it.

but will charging it overnight bad for it? so it dosnt overcharge? i thought i heard someone say that so i try to charge it before i go to bed then charge more in the morning but i wasnt sure if Li batteries would overcharge or not
edit: nevermind i just read that it is not possible to over charge a batty but it is bad to leave it charging for more than 24 hours because it will over heat and can cause internal damage to battery and to phone

Some battery saving automation
Ran across this a couple of days ago:

Been running it on my Aria on CM6.1-RC1. So far running as advertised. In areas with weaker 3g coverage, switching to 2g has cut my battery usage in about half. I've really only used this to turn off 3g, as I need 2g on all the time for push gmail and im, and am using setCPU for cpu clocking.

i am running Liberated FR006, and have no plans on switching to anything else (maybe the official 2.2 release, but not likely). when should/can i wipe battery data? i've had the phone since june and havent wiped it.

Interesting. I was wondering about this the other, thinking that perhaps my battery life has gotten worse since I put the phone in a silicone case. Is that perhaps holding heat in/creating overheating and battery drainage?

Battery Life

Hungry Man ~
Lately I've been running the latest update of the same ROM (Nonsensikal Froyo - now 15.2) without any CPU apps (no o/c'ing through script either), no autokiller, no battery tweaks (just Juice Plotter) only 1 widget (Fancy Widget Pro), JIT enabled, VM heap @32, compcache @18 (default) and depending on which app I look at, TiB or RE, I have +/-110mb of free RAM, very minimal apps. Also, I upgraded to CFSv9. I even bought a Seidio Innocell 1750mh extended life battery. I recalibrate my battery after flashes ....
Oh yeah, a little more info, I am not a power user, just an average user with poor to ok reception, I tend to use wireless at my house b/c reception out here in the woods ain't good, but turn it off when not needed. I use airplane mode during sleeping hours as well. The max of my battery usage is Display, then And OS.
Ok, now the question ..... If I don't use airplane mode, I get maaaaaay-be 6-8 hours of average phone usage, usually less !!
What finally broke me to PM you now is that (i recently put numbers on my battery icon) while typing a text message earlier (a few minutes tops, not on wireless) I watched my battery click down from 50 to 48 !!!
When I charge my phone full & I easily lose 10% in half an hour (I've tried this with SetCPU, JD, CBT, Super Power, CPUBoost Lite - I think you get the gist) ... and not including airplane mode, I NEVER get more than 6-8 hours of battery life !!!
Is there any knowledge that you can give me on this issue or have I pretty much exhausted my options ? I am this PM short of resigning to crappy battery life
Many Thanks for your time ~
Matt

What does the phone/Spare Parts say is using all the battery? Have you tried flashing and then using the phone without installing apps (other than the essentials?) Are you leaving the phone idle, screen off, and noticing the same big drop?
You could try going to stock for a bit to see if it improves...or trying a different ROM. Maybe you have a dud battery?
Edit: Sorry, you may have meant this to be directed at someone specifically.

Just an observation. If you're not using anything to overclock the phone maybe the battery life would be better if you at least underclock it. I suggest Conap's CPUBoost Lite, free on the market and here. Just set the minimum frequency to 245760 (my suggestion), and I currently have the screen off Minimum to 19200 and the screen off Maximum to 480000.
Also, I used to use Juice Plotter. I theorized that maybe Juice Plotter wasn't great for my battery itself.

I noticed the same thing when I used Juice Plotter. I got significantly less battery life when i had it. Try deleting Juice Plotter and see if you get more life out of your battery.

well you've noted your in a poor coverage area, and that is your problem, nothing can completely fix other than moving, but you may want to research flashing a new radio, becareful and check your md5 hash sums

Actually, the Verizon Network Extender can definitely help without moving. http://www.verizonwireless.com/b2c/store/accessory?action=gotoFemtocell
It's $250, but probably a lot cheaper than moving, and it should help with battery life. It does with me - I get 24-32 hours on a 1750 battery, with WiFi on all of the time (I have the old, non-3G extender.)

I'm running Tazz Froyo and get a minimum of 24 hrs on stock battery. I would try changing roms.

Battery life on my eris was never good, that's why you buy a extended battery. I have the biggest one that they have on amazon and my battery can last for five days with average use

so my battery has been draining really fast too, but my question is does the battery recalibration work? some people have said their battery drops even faster but is that only the first time?
PS. ive been on xtrrom for awhile now (like a month and a half) and it just started dropping. spare parts says android system is greater than the rest, if that helps

Yes, it works if you do it propely. Charge phone to 100%, boot into recovery, wipe battery stats, reboot phone. Use your phone as normal until the battery is fully discharged and it shuts the phone off. I sometimes try to turn it back on also just to make sure it is all the way dead. Plug your phone in to charge it, walk away, don't touch it until it is 100% charged. Turn your phone on and use it as normal. It sometimes will take a few times charging it to see a difference. If I missed anything or mistyped anything some one correct me please lol

consistently mediocre battery life even after calibration and undervolt

I just can't seem to crack the battery life conondrum. I've calibrated (charge to 100%, wipe stats, then full cycle).
If I'm listening to music its consistently I'm sucking ~10% an hour, if idling ~4-5%. Which means I'm getting around same battery life as my old nexus one – mediocre, I end a working day with around 30-40%. If I want to go out after work i have to remind myself to charge during the day...
Right now I'm even running a mild setcpu undervolt (with faux123 kernel) and profile (screenoff max cpu 600mhz) but seeing not much improvement if any.
I am on gingerbread AT&T radio so thats not it either... any tips aside from 'use juice defender' (which I don't want to do as I want always on data instant push etc., I know juice defender basically shuts your data radio off)?
Note this is the same with stock gingerbread as well as the ROM and kernel I'm currently on (redpill, faux123 kernel)

I've done everything you have and i'm on a Bell Atrix....i have been looking into this for about a week or more and i just can't crack it either!!! it's driving me nuts and i have spent sooo many hours googling, searching xda and other sites and have tested MANY different methods and still can't seem to figure it out. For me i know its the phone idle...but what it is i can't tell, i have SystemPanel monitoring as as well as watchdog which i alternate with. Flashed the battery calibration fix and calibrated the meter blah blah blah....driving me nuts and i know its not a faulty battery because before i unlocked and flashed 2.3.4 i could get about 30 hours with heavy to moderate use!!!
For the love of god i wish a team of dev's would look into this!!!!!!!!

Honestly none of the faux kernels worked for me... Try gobstopper, stock kernel with watchdog was the only combo to give me good battery life. Not to mention lock sounds works properly, and its fast. All bell users should use it. Seriously... 19+ hours worth moderate usage.
phone idle is still high but it seems to be a slow drain.

a.) not an option for me, AT&T phone
b.) I'm not seeing faux's kernel do any worse than stock kernel, I don't think its the kernel?
c.) yeah I tried system monitor as well, the highest process was opera at 3%.... 3 lousy percent lol

1. Calibrate your battery again (I have posted a guide in the General section)
2. Flash a kernel which allows overclocking, install SetCpu, add battery saving profiles (downclock to 500mhz on screen off, downclock to 800 mhz when battery less than 30%, downclock to 800mhz if temperature higher than 50C)
3. Freeze all MotoBlur bloatware (there's a guide in the general section)
4. Disable data and wifi unless you need it
5. Install Watchdog and set it up according to instructions I provided in my calibration thread.

Well, if you keep data or wifi turned on at all times, then there's no way you can have something more than mediocre battery life, sorry.
It's not the Atrix'es fault, its the brutal truth with all modern smartphones.

it is not a kernel issue, i simply dont know exactcly what hack in particular gives ninja the amazing battery life. but im working hard to determing this so i can share it.

The people in this thread have listed all known steps to improving battery life.
If you really follow all of these guidelines and have bad battery life, you might want to try a battery replacement.
If you are sure your battery is not the problem, you might also want to try a couple of custom roms. Who knows maybe you will get lucky with one of them.

Is there any way to log off from motoblur once you are in so you can stay offline? Of course any connection that gets cut will increase battery life.

I don't understand all these battery life problems. Its got to be an app you are installing or your battery is buggered!
Admittedly when I first installed 2.3.4 OTA, battery life dropped like a stone, but I drained it flat, and then charged it up again and its been fine ever since.
I'm running on stock 2.3.4 without root, and I have quite a lot going on (IM's/Facebook/Twitter) and I can last well over a day and a half with moderate use, this includes sms and calls.

Battery life is a very subjective issue. One person might be fine with the phone, while the other person will say battery life is terrible with the very same phone.
Besides the obvious drainage problems, it all depends on how you use the phone.

Honestly the best thing that worked for me was turning off "Syncing".
I currently have 3G on, BT on, ETC...
Syncing in the background killed my battery life. Now I usually make it through the day without the need for a top-off...

Im in stock gingerbread and battery life is definitely worse than on stock 2.2.2 and and im basically running the same Apps. I am a heavy user and I used to drop 10% per hour. Switch on at 7am and by 5pm I was changing battery. Now I am switching around 3pm.
That's why I have 3 batteries!
I still think its better than nearly every other device I have owned but that nay be because battery is larger. I dont know why they don't design to put in 2400 mah batteries (my treo 650 had one!).

The treo 650 also had a thickness double that of the Atrix .

The batteries in your phone are high-capacity lithium-ion batteries. This kind of battery technology cannot be simply reset and “re-calibrated.” When you follow the steps to recalibrate your battery and delete the batterystats.bin file from your phone, you are getting rid of more than what you think… Stored inside that batterystats.bin file, your phone keeps detailed logs of the capacity of your battery and uses it on how it can be utilized more efficiently. By deleting this file, it basically wipes the phone’s memory on what the battery can really do. This actually does damage to your battery by using up valuable charging cycles, all while giving a fraction of battery life and performance.
Now, you might be saying uh-oh, I’ve already re-calibrated my battery! What do I do?!
Well here’s your answer. Use your phone like normal. Yes, your battery and phone wont perform as good as it can for a while, but after a few days, you will notice that it starts doing better and better. Give it time, its trying to rebuild all those logs that you just deleted.

This is the first time I am reading this sort of opinion, though I have read countless info on the subject.
If you want to make such a strong point, you better have source to back up your opinion (article, studies, other source of proof, etc).

These threads are all USELESS without NUMBERS.
Like another person with common sense already stated in this thread, you need to provide numbers.
GB has this improved tool (over 2.2) where you can see how your battery is wasting its juice. Watch those numbers for a few charges and then POST THEM TO COMPARE.
Saying your battery sucks without giving any numbers is like calling a color ugly.
(just in case someone misses the points, without numbers it's hard to compare, since it mainly becomes an opinion at that point)

I recently did a battery calibration on my HTC Leo with MIUI 2.7.27 and now it does last much shorter than before i did the calibration. Does anybody know why this is happening? Before i did it i could use it a full day without charging, but now i have to charge it twice every day. And that does not work too well since i still go to school. Besides, i just want to be able to use it a full day without charging. I calibrated it with the built-in MIUI battery calibration app.So it happened like this:
1. Fully charge it.
2. Click the ''Calibrate Battery'' button.
3. Fully drain it (I drained it until it indicated 7% because i use MAGLDR and we all know MAGLDR can't charge if the phone is turned off. If i would have drained it fully i wouldn't have been able to charge it again and it would be useless.)
4. Fully charge it.
And no improvement, it only got much worse. Someone, please help?

Calibration
These are threads on calibration just in case... http://forum.xda-developers.com/tags.php?tag=calibration
Nonetheless, i had the same problem too, what i did was i drained it to 2percent, power off, on, mgldr reset bat stats, and charged without break, and when the green light shows add another hour (i've read it somewhere in the threads).. As of now from 8AM to 6PM, moderate use still have 50percent using Team Blue Droid SENSE 3.5+ HTC ONE X TWEAKS TMO ROM.

Hope this helps...
Thanks sundawg for the rom.

Thank you, but i am afraid that if i drain it to 2% that it won't be able to power up and boot again. If it is below 10% it drains battery extremely fast, and that would be a waste of a battery. (I've got another one lying around so it woulnd't be much of a problem though) Please advise me, should i do the same as you? By the way, i already noticed that if the green light shows it is not fully charged, but thanks for confirming i was right
Anyways, thank you for your help. I might give it a try when i am more sure about if it will power up with only 2% left.
P.S. Sorry for my english, it is not my native language

Battery drain is a common problem and a lot and I mean a lot has been written about it, just like roms where you have to make a trial and error method which suits you best, you also have to take into consideration battery quality sans its true capacity. In my case, I simply follow the dev's advise on battery tips. Since you have an extra battery, choose your best performing battery, and drain it to at least 5 percent and reset battery stats in cwm. Reboot it and charge without break, no sim , so that not to disturb it until the green notification kicks in, patiently add another hour just for keeps. Use it and sometimes it seems that there is no change but again patience is the key , Let it work out more until the charge settles and hopefully you get a better battery output and with correctly reported stats.
Finally, a rom that would not be too much demanding on power, one for daily use, devs post them if it is for daily use. Practically, only the apps you really need, a little eye candy, and simple games. Ciao!

One more question: How do i find out which battery performs the best? Simply by trying? Anyway, thank you for your advice, i'll try it for sure one of these days.

is wiping Battery stats from CWM better then using Battery calibration from play store?
