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

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.

Rom with the best battery life

What Rom is getting the best battery life these days

also doesnt matter if its sense or vanilla or stock OTA i just want good battery life

from what i can tell, battery life is MOSTLY tied to the kernal. Try an undervolted one, i've found they all work pretty well (hydra and KK)

o alright im using kings #2 BFS kernel undervolted and underclocked

I research before I got my DINC so I never used the factory battery from day 1. I have the same size battery but is 1750 power rating... I think Verizon has a newer one which was before I got mine...

Not directly related to the ROM. Check out the Hydra kernels. Also, with regards to battery, you need to do some recalibration so it works better. I got the 1750 battery for the DINC and it was dropping battery very fast no matter which ROM/Kernel combination I used. Finally found a thread that discuss how to get the OS to read the battery levels better. As an example, my battery would run down from 100% to 90% within 10-15 mins! After trying the following, everything works better.
Here's the thread: http://forum.xda-developers.com/showthread.php?t=714471&highlight=battery
Here's a summary of what you need to do:
01. Power off phone and change battery to full level (Green light).
02. Unplug the power and plug it back in. It should take another 15-20 mins to go green again (there's a thread discussing this also -- "bump" charge).
03. Turn on phone and go into recovery mode. Remove the battery stats.
04. Reboot phone and use without recharging until the battery drains completed - i.e. phones shuts off. May want to turn it on once it shuts off.
05. Charge normal and you should see a positive change in the battery life.
Hope that helps.

Yeah but how much do you really gain by doing all that? And how often if at all do you have to do it again. I have the 1750 and it seems to depend allot of what kind of signal and which radios are on.

Of course if you had bad or no signal, the phone will use up more battery. Normally when you don't have any signal and you check the battery status, the phone tells you to put it in Airplane mode to conserve battery.
For me, it's worth doing because my battery does not drain as fast for my usage. Since I did this over the past 2 days, I've had the phone one on a single charge with about 6 hours of Awake Time (gaming, Internet, phone calls, texting, emails, some GPS usage) and UP time is 22 hours. And the battery is down to 20%. Definitely an improvement for myself so just try it if you like and see how it works out. Everyone's usage is different so it's hard to quantify.

bump charging before wiping stats makes no difference. bump charge is still necessary regardless. until htc acknowledges its a problem and fixes it on their end, bump charging is a part of our lives if you want a fully charged battery. unless you use an external charger of course.

I charge externally and I still bump charge tho I don't need to power the phone on and off. Also the bump time is much shorter

Nah, Virtuous gets really good battery life, especially with the custom kernel built for it.
Does JuiceDefender even function on CDMA phones? I thought it wasn't working

I would also like to know this! What about SetCPU profiles too? I just want the best possible battery life, speed is not very important to me.
So, who has tried out various ROM and Kernel combinations? What have you concluded gets the bets battery life? Thanks!

im in the proccess of downloading and setting up virtous ill report back with different kernel set ups. i just want a rom and kernel set up that will last easily the hole day

Bump charge with or without battery stats wipe doesn't seem to make much difference for me. I plug in at home/car/computer and carry a spare battery. Just wish there was a way to turn off 3g and force 2g with Verizon on CDMA phones. That way I could still have data/internet.

[Q] ROM problem or my battery?

Currently using Stepp_aospX 1.0.0-MR2.
When I'm watching a 30 minute YouTube video, the battery goes down by about 45%. When I turn off the phone and turn it back on, the battery jumps back up about 20-30%. Now I'm wondering if this is a problem with by battery or with the ROM.
Can anyone else get this issue to occur on their phone?

probably the battery, how old is the battery? Any water damage?

I'm using the same battery the phone came with (bought new 2 years ago). No water damage.

Two years is a lot of time bud, thats the problem right there.. Batteries wear down, imagine how many times that battery has gone from 0% to 100% in the course of 2 years..

Yeah, it sounds like you need a new battery. Anker makes great ones, they aren't too expensive, just buy them off of amazon. Before you do that, take out the battery and check for lumps or stuff like that.
Again, there is a 90% change that you just need a new battery

That's what I was afraid of. No lumps on the battery (thankfully). Probably not going to buy a new battery though. Waiting for a good deal on a Galaxy SIII or Nexus 4.
Thanks guys.

Someone once said to charge the battery to 100% then clear battery stats then drain it down to almost 0% then clear stats again. then charge it back to 100% in one sitting. that helps me sometimes when flashing an old backup and the percentage jumps around after a reboot.

Thats a placebo. It really doesn't do very much. If you get random battery level jumps, its a sign that you need a new battery

Spin it

Ive found that a lot of times you can't see it starting to bow, but if you spin it you can tell. If it just spins 90-180* then it's probably ok, but of it spins more than that it's bad. I grab the battery charger + 3 batteres from eBay for under $10. Now I just swap batteries rather than charge the phone.

[Q] Miscalibrated battery, need help!

I need some suggestions on how to calibrate the battery on my n4. It got miscalibrated when I did the update 4.2 to 4.3 and I haven't been able to calibrate it since then, a week ago.
I tried using battery calibration from the store but it didn't work, I tried charging the phone from 0 to 100 and it didn't work.
I remember I had the same problem 2 years ago with my Atrix and I solved it by wiping the battery stats from recovery, but now twrp and Cwm removed this feature and I don't know how to solve my problem.
Maybe it would help flashing all back to stock with the toolkit?
If you have any suggestions I'd really appreciate it.

Just the answer I didn't expected, and frankly a pretty useless answer, everybody knows that battery calibration doesn't improve battery life.
But I have other problems, like I turn off my device at 80% and when I turn it on it's at 77%. Do you think that's normal?

Either faulty battery or do the following:
1.Completley discharge N4
2.Charge fully(+2 hours after hitting 100&) WITHOUT disconnecting from the charger.
3.Repeat for better results.

You mean off as in all the way off? If so, then that ~3% is being used when the phone boots.

I've had many phones, and none of them lost charge during the boot, at least not that many. I think that's the clear sign of battery miscalibration, I've had this problem before with another phone. Besides that, I've had a strange behaviour of the battery, for example I saw it lose 4% in 1 second, from 66 to 62 in a blink of an eye.

It's not that it's losing charge quickly, it's just the OS (or the hardware itself) doesn't always do the best job of reading it. There's not much you can do about that, and it's really not an issue unless you make it so by staring at your battery level all day.

Hi,
I'm having a similar issue. Phone rebooting to weird battery levels (not the %age it shutdown at).
Phone shutting down at 31% battery and rebooting to 0%.
I tried charging only to 100% yesterday with the phone ON.
Do I have to charge it even after it's charged to 100%?

I tried charging through the night and then discharging it completely and charging it completely again. I also tried deleting the batterystats file (even though I know it doesn't do anything)
So what do you suggest I should do? Get the phone replaced or get the battery changed?
I live in India and the phone is from Canada, so replacing the phone will take some time but I can get the battery replaced for around $20
Also my nexus is also showing +ve mA values while it's not charging, and the values are absolutely crazy, +268, +168, +1171 (in batter monitor widget)
Please tell me what I should do.

Before you replace the battery try to disconnect the battery's flex cable and reconnect it [after you charge to device to 100% and turn it off of course] check if its 'reset' the battery.

Getting less than an hour of SOT with a new phone and battery

I am in desperate need of help, I've only had this phone for like a week and I really like it but the battery life is abysmal. I'm getting less than an hour of screen on time, the phone is using about 10% per hour when in my pocket.
I've done the factory reset, deleting everything, downloaded greenify and absolutely no progress has been made.
Phone Idle and Android OS is sucking up about 20% of my battery. For the first couple of days I was getting about 2 hours of SOT and that's the best I've gotten so far. I just bought this thing and I really want to keep it but I can't afford to have this thing dying on me when it's just in my pocket don't nothing. Please ANY help would be appreciated, thank you!

Seems to me you may have a flawed device? 2 hours sot at best with a new device and new battery is horrendous, I have the T-Mobile variant as well, was refurbished and I'm getting a solid 15 hours with anywhere from 3.5-5 hours sot! Depending on usage so I believe you may have a defective V20 friend. I'm going to keep an eye on this thread see if anything comes up

Is the battery new, is your phone refurbished, water damaged battery? Old battery in New phone? Something is up with your battery it sounds like. Would be the easiest thing to replace and test. It could be the phone itself having a hard time receiving the charge (faulty pins)

The phone was new for sure, but the battery was already installed in the phone when I opened the box. Is that normal? I watched a couple unboxing videos and they had the battery separate.
