I've been running the latest BAMF DESENSE . By going through the settings and setting up set CPU with some good profiles I've been able to push my TB through the day with battery to spare.

Imoseyon's Battsaver leanKernel with TeslaCoil has served me well.
Today I had about 13 hours of uptime (with ~5 hours of being powered down,) and about 3 hours 50 minutes awake time. Pretty good, I think.

Thanks.... I think ill give teslacoil a try .... Any other ones ....

I've been running the new BAMF 1.6.3 remix with the new included kernel and its been about the best I've tried so far.

My problem is that I work as a field engineer, so I spend a lot of time in plants using my phone as a tethered wifi internet connection (in fact, I'm posting from it right now). I have yet to find anything that lets my phone last more than an hour while connected to 4g and using Wireless Tether. I realize those are probably pretty extreme circumstances, and I get by since I bring a wall-charger with me to plug into whatever electrical panel I'm working at, but I can dream, can't I?

the bigger question here is what kind of plant lets you take your cell phone out around the plant? Those are supposed to be no cell phone areas

Exactly. The majority of my work is in "big 3" automotive plants, and they have "no picture" rules, and "no walking and talking" rules, but cell phones aren't banned.

Yeah, this sounds like me. Battery drains like crazy regardless of what roms/kernels i use. My radio, in CM7, is currently set to CDMA /EvDo Auto. Is there a more efficient one that wont put me down to 2g speeds?

Wait, does that awake time mean screen time? It only takes me 2 hours of screen time, at most, to get to 63%

Are you overclocking the bamf 4.4.7 kernel at all or running stock speed?

uptime: time the phone has been powered on
awake time: time the phone has been on without going into sleep mode (time it has been doing stuff)

Leankernel extreme with setcpu limiting to 1ghz. Also, screen off @ 245mhz. Runs great even when playing music. I set to 3g using lteonoff app but it doesn't make much difference if you're going to be leaving on an app such as skype that constantly uses data. I have set everything to sync manually except for email. At lest it runs all day with light to moderate use now instead of draining 5% per minute from just check my email. My backlight isn't set past 40% (can't see the screen if I'm outside otherwise.

[Q] Kernel Help

Right now I'm running H57 with JT's 4/15 voodoo kernel. For the past few weeks my battery life has been miserable. I've tried several different Kernels, wiping, data, cache, dalvick cache, and battery stats. Ever since the bad battery life, I've noticed that the Android OS is consuming much larger battery percents than it used to 30-50%. It used to stay around 5% or less. Also I been using CPU spy for a couple weeks. My CPU seems to spend almost all of its time at 800 Mhz for some reason. It will not power down to 100 Mhz even if I turn it on and leave it in my pocket for a few hours. Today i've burned 80% of my battery in 5 hrs while it sat in my pocket during an exam. Any advice on what I can do or check to see what exactly the problem is?

Im not quite sure what the issue could be but I can suggest a program called osmonitor that might help you narrow down what rogue process is eating away. i recently just upgraded from 2.1 to 2.2 as well. I am running JTs 4.15 voodoo kernel. My battery seems about the same so far as 2.1, maybe something with H57 ?

Yeah, I can try another rom. It was happening prior to H57 though. I've been on 2.2 for a while now. 2.2 was running great at first. It happened while on PNP. At first it was amazing on battery. I don't remember changing anything specific to ruin my battery life. To the best of my knowledge it occurred after flashing OTB on PNP. I'll download osmonitor and see what i can find. Thanks.

I'm pretty much stock / rooted w voodoo and about same as eclair check the misc section in osmonitor for cpu scaling

Er you're roaming?

Yeah, I'm pretty much always roaming. No USCC in Raleigh where I go to school. The only time i'm not is when I go back home, which is not a whole lot anymore.

That is likely why your battery life sucks. The phones is constantly trying to find a better signal. Also, USCC doesn't always enforce this but they do have a clause in the contract that they can shut down your line for using it more than 50% of the time outside of their network. Just something to keep in mind.

Yeah, I've heard that, but I've had uscc up here for 3 years now. It used to be fine up here. I've had it in raleigh for 6 months and it just start acting up about 2 or 3 weeks ago.

I'm going to be in uscc service for about 3 weeks here. I'll see if it makes a difference.

And the answer is no. I charged the phone over night. Left to fish at 5:30 this morning. Unplugged the phone and turned it on when I left, turned off tasker just to be sure that wasn't causing the issue, and left the phone on the table at home. Back at 3:30, phone at 35% not even using it. I can't find anything using osmonitor. When I look at it, osmonotor is usually using the largest amount of resources.

Battery life is not something people can fix for you, there are too many factors that affect it, u just need to troubleshoot. I've had various results with different roms but typically it is your usage and the apps on your phone that are culprit
Sent from my SCH-I500 using XDA Premium App

I completely understand that. That's why I spent a couple weeks troubleshooting to try and find out what the problem was. Like I said I can leave the phone on all day and never use it and the battery still sucks, so It's not usage. I can not find any apps that are consuming much battery. The only thing I changed between good battery and bad is from JT's voodoo kernel to OTB. Android OS and System began to use 60% of the battery and a 5 minute phone call will burn 5-10 %. I said that sucks, switched back to JT's kernel problem still persists trying different roms and kernels. That's why I posted this to see if something could have been messed up when flashing to OTB.

I had mine up I think for like 182 hours something.

Before I started playing with GB, running Perception 10.4, I saw 194 once, and a few 170s.
Now I'm not even on the same ROM that long.

You can go weeks if you make it a Captivate Touch.

I has just over 1,000 hours... Yep, over 40 days.

You know you can actually find a definitive "up time" in settings> about phone> status right? All the way at the bottom.

CM7 USERS. how often do you upgrade

I usually don't flash a new version of cm7 until 8 to 10 nightlies pass. I'm on 51 now so ill prob wait til low 60's to flash again. How often do you flash or upgrade?
ITS ALL WONKY!!!

I usually look at the changelog to see if any big updates have been made and then look in the nightly thread to see if people are having problems. If not, I'll flash.

You're missing out. 56 is a rock!

I flash every 2 to 3 nightlys unless changelog shows they have change something dramatically. On 54 right now

yup I do the same minus the nandroid backups... I live on the edge
( I do have them but they are like a week or two old)

I upgrade once a week..

everyday unless there wasn't really anything changed. remember all you have to do is flash an old version no need to do a nano since when you flash the old version it over writes what had changed. I also do a titanium backup before each flash since if i need to wipe that puts me back to where i was at anyway.

I just have my stock nandroid backup in case I ever want to go back

I upgrade daily in the morning.
#55 and #56 have lots of new fixes.
Battery Driver, Dual-Radio bandwidth (doubles bandwidth), Builtin Notification Backlights, etc.
I don't see much difference between #55 and #56 but I'm sure there are some tweaks. So grab the latest and go. Anyone using CM7 should upgrade to #55 at least.

Nightly, and literally nightly.
Haven't run into crashes since well, i reboot every darn day.
While charging overnight it does freeze (known issue seen other have same issue).
That darn battery.
I took a break from CM7 just to try Evil's ROM. Also other reason I stopped was the brightness issue. 55+ the issue went away.

The brightness was fixed on earlier roms but came back, then went away, and came back. Brightness bug came back around #53 and fixed on #55.
Mine doesn't freeze, reboot, or lockup while charging over night... on any CM build.

I'll be honest I'm rooting for CM7 and will be my final ROM when it reaches stable/RC version. The crashes/reboots are gone and I don't keep the uptime past 20+ hours because I keep flashing to the latest ROM.
Battery freeze is disappointing, but I blame it on the hardware/LG. Its not perfect but its getting there. Gingerbread update will fix this. It better

I usually look at the channel log to see what has changed, but every 2-3 days. If I am having good luck with the current build I will stick with it, if it is giving me issues, I will update on the next build. I was on 54 for 2 days (with the same battery charge) and updated to 56 yesterday. After only using 20% of my battery after 12 hours of mild use and a lack of any cool/important updates, I will stick with this build for another day or 2.

You really should update. 54 fixed a LOT of problems: the battery meter now gives accurate readings and data speeds are doubled.

Any time there is fresh Gigglebread;-)

I was updating every morning before work but right now im on 56. Its been running pretty good for me so im probably going to stay on this one for a little bit.

I know. I wanna be done with this backloght crap but I'm gonna wait until I need to reboot because I wannna see howblong of an uptime I can have. I'm just about at 105 hours ans no reboots so far.
ITS ALL WONKY!!!

I flash almost every day. I keep nandroid backups on my SD, my desktop and my dropbox. I guess I'm paranoid.

I can't shake the Android OS from draining my battery.

I've had this problem once before and it was simply as easy as switching my kernel. You can see here.
Now I've tried GR to CM9 and then to Codename Android Build 4 still had the problem changed Kernels.. Then decided to GR to CM9 and try Beam, and yet again still had Android OS draining the battery. I then flashed the Hefe kernel and NO change.. I've looked around on forums and remember seeing someone mention strange battery stats I can't find it at the moment, but if you look at my stats below you can see that not only is the Android OS draining the battery the graph shows huge drop off points. What exactly are those? Thanks in advance for any help!

That looks like you need a new battery. A couple weeks ago I had the same problem. My usage looked the same as yours where there were sudden drops in the battery percentage. I suspect you have the same problem.

Have you tried clearing cache, clearing dalvik cache, then fixing permissions, rebooting and waiting at least ten minutes after reboot? That is what always fixed my "Android OS problem"

I started on stock GB, went to the 1 click stock with root and CW, to CM9, to Remi's ICS. This is what my battery looks like

@getochkn
Yeah, but you were sleeping or doing nothing, phone was idle. LOL Seriously, how is that possible? I have tried many ROMs, today I had a big issue on CM9, battery dropped from 60's% to 1% when phone got stuck and shut down. I had an emergency and needed my phone to call and couldn't. I got very pissed off and now I'm on GB because that battery drain issue has been all over ICS. I have tried calibrating, GR's, I use less apps... nothing! Phone lasted like 4-6 hours with average use. I needed to charge it like 3 times per day. It made my mobile phone, not so mobile.
Not complaining. Just a real issue. I know there are bugs and that development is ongoing. I love ICS but just can't afford to loss so much battery again in another emergency case scenario.
I would be happy to get 12 hours of use. I remember with Redux 1.2 (GB) I got 18-25 hours depending on use. Share some of your usage. I may need to buy a new battery.
