I recently flashed Froshedyo to my eris and my fiances eris. I set up setcpu and auto killer its now on aggressive. Today uninstalled setcpu thinking that it was affecting battery life since my fiance mentioned that his battery went from 90 something to 54 in 30 mins. Mine went from fully charged to 61 in less than 3 hours. We dont use our phones heavily. I do use the internet most days but not for long periods of time. I did wipe the battery stats on both phones and still havent seen much of a difference.
My question is, is there anything else I can do to get really good battery life. Do I have to do the collins battery tweak because I was going to try that next or would I have to end up switching roms which I really dont want to have to do but will if it will mean improvement. Id like the phone to not be dead after less than 24 hrs of use. Thank you for any help.
When you flashed and wiped battery stats was the phone fully charged then did you completely drain the battery and then charge to 100%? Do you have wi-fi and or blue tooth on all the time? Just trying to start with the easy things... I've heard of no issues of bad battery life with sheds roms. In fact quite the opposite. But I think his includes cpuboost in which case you don't need set cpu as they will conflict each other.

I charged the phone to 100% wiped them this morning and then went about using the phone as I usually would. Sounds like I missed a step. So I have to charge to 100% then let it die then charge again then wipe? I
I never have wi-fi or blue tooth on.
Yes the rom did come with cpu boost. I believe I have that set 710/245. Should I change that as well?
i found this very useful on the desire forums

After much googling this is the way that seems to be best when recalibrating battery. I just see so many people with poor battery life and it's likely because you've flashed new kernels and roms 50 times a week =p
Minor update! I recalibrate my phone today and realized something, this is reflected in a few new steps.
Step 1: Charge phone to 100%
Step 2: Wipe battery stats and shut phone off.
Step 3: UNPLUG PHONE and power on
Step 4: Leave phone on until it it shuts itself off. Do not plug it in.
Step 5: Turn phone back on, still unplugged. If it can't turn on that's fine. If it can turn on let it fully drain again.
Step 6: LEAVE PHONE OFF. Plug the phone in and let it FULLY charge without interruption. I let my phone hit the green light and then wait an hour before step 7.
Step 7: After it's hit green and you've waiting a while unplug your phone. Do not turn it on. Wait a minute and then plug it back in. If the light stays amber for more than a few seconds (like 10 tops) leave it charging again until it's green.
Step 8: Repeat step 7 until the light turns green very soon after you plug it back in.
Step 9: Unplug and turn your phone on. Enjoy your (hopefully) extended battery.
I also suggest using "Juiceplotter" widget. It "records" your phones battery usage and uses it to predict future battery life. It won't work perfectly for the first day or so but after it gets used to your habits it's very good at predicting.

I am going to have to try that. Thank you. =D I hope it helps.
Charred the phone to 100% then wipe battery stats. Let the battery drain till the phone shuts off then charge it again. Wait untill its fully charged to unplug it and power phone on. You shouldn't need to wipe everything and flash again. You also dont want to use cpuboost and setcpu together. That will cause conflictions. I can't say on the settings because I don't use either of these. Im also not sure about task killer.

Thank you again. I only installed the auto killer due to I read a few places that it helped a lot I personally haven't seen much a a difference. How long does your battery last just out of curiosity.

I would probably get about 30 hours is my estimate but I plug it in every night. I use mine alot... some would almost say heavily. Lol. I would probably say moderate though. I don't use any cpu o/c apparently or task killers myself either.

***NOTICE***
The ROM Manager version of CWM does NOT wipe battery stats properly, as with many other things. What you need is jt1134's version of CWM that is all happy and works and stuff.
You can find his happy CWM here. And here. And also here.
And here.
Big thanks to LegionTHEFecalExcretion for the heads up on that.
***END NOTICE***
NOTE: On current DL30 and EB01 ROMs, you will not see battery life like you did on DL09 with undervolted kernels. There are NO undervolted kernels as of yet, everything kernel wise with Froyo ROMs in very much stock. These steps will improve your battery life in comparison to when you flashed Froyo, but you are not going to see spectacular changes in battery life up to what you were getting with undervolted DL09, etc. It's just not possible until we get undervolted kernels and Froyo matures for our device, development wise.
Hi everyone, I've been seeing a lot of threads about bad battery life, whether switching to Kaoscinate, Vanilla, or DL30. Stop it! Just kidding. There is a simple process everyone should follow when switching between different enough ROMs, like AOSP, CM6 and TW Eclair and Froyo. This is how you retrain your battery.
1. Charge your battery to 100% (when it gets there, let it SIT there, your phone is NOT reporting correctly).
2. Reboot to Recovery and Advanced -> Wipe Battery Stats.
3. Reboot, and use your phone until it is VERY low (5-10%, you can let it die if you want).
4. Charge your phone back to 100%
5. (Optional) Power down, then power on phone. (Thanks goes to BrwnSuperman for this suggestion, give it a try!)
Your battery issues should be solved. This needs to be done every once in a while, especially when switching between different ROMs and OS versions.
User dalrym05 posted this alternate method for retraining the battery on page 4 as well, so I thought I would share it here in the OP. I'm posting this as a USE AT YOUR OWN RISK method, as I have not tested it, and am not quite sure what the *228 steps for it actually accomplish and have to do with retraining the OS battery reporting, so I'm leaving it quoted to dalrym05 for the time being.
dalrym05 said:
Here were my steps to better battery.
1.*228 option 1
2.*228 option 2
3. Run battery completely dead to 0%
4. Plug in and boot immediately into cwm
5. Wipe battery stats and dalvik cache
6. Reboot and let charge fully before unplugging
7. Completely discharge again and fully charge again.
After this you should notice a very nice increase in battery as I did. My battery life is back up to par with eclair.

HybridByNature had an excellent suggestion on page 4. If people have good tips and tricks for maintaining good battery life, and they are easily reproducible, then I will gladly add them to the OP here. What works for you?
HybridByNature said:
This might also be a good place to add tips & tricks to extending battery life.
IE
-Close programs that you aren't using.
-Don't leave your camera or navigation running in the background.
-Turn off WiFi & GPS etc when you aren't using them.
-Don't run your screen at full brightness if you can help it.
-Figure out what uses more battery life than other things:
Pandora, internet browsing, downloading, camera/camcorder, Angry Birds etc.
If you are rooted, try and narrow it down to the best kernel/theme for your situation. I've found that I have better battery with a non-voodoo kernel but the performance increase is worth it so that's a trade-off that I make.
Let's hear from our readers: What is working for you?

Would not surprise me if this is all it is. I have turned my phone off at 5% for an hour and turned it back on without charging and then it showed 45%. I know when batteries are low letting them sit a little bit can help, but not that much.
It is just being reported inaccurately by the OS.

Yes, but not as a thread, it gets posted in everyone else's "Why does my battery life suck ass" threads, so I made this so maybe people would see it and try it before posting another useless question thread in Development.
Definitely works though. Did it yesterday. Good post. It has been posted in other threads ... but I think we all know people don't read through everything very often.

I have the battery charger and 3 batteries, I always run my battery low and leave it in the charger for a day.
I did this last night and it didn't work too well for me.
Also, when I go to wipe battery stats in the recovery, it doesn't tell me if it wiped or not, just goes back to the advanced menu.
And also, should I be concerned that when I cold boot into the recovery, it doesn't appear to be CWM? It says Android recovery...I know I have CWM recovery installed.

Wow same here..I just took mine off the charger bout 10 minutes ago and it's at 95% now. I guess I'm gonna let the battery run completely dead and charge it and see what happens.
I did something similar. I charged to 100% while it was on, removed from charger then powered off. When phone was off I plugged charger back in and waited til it was at 100% then unplugged again and powered on. Waited until phone was completely on then unplugged again and connected to charger. Waited til it was at 100% and while still plugged in at 100% booted into recovery and wiped battery stats. Then rebooted phone into OS and unplugged. I had tried this previously with DL09 and it helped a little. Last night I wanted to see how my battery would drain after doing this. With WiFi on and I got about 10 emails during the night, from 8:30pm to 6:00am I lost only 13%!!! Previously I would have lost from 35 to 40%. ymmv

This is a proven technique, and it takes patience. Seeing the battery drop from 100% down to 95 or 96% after unplugging is normal behavior. I've done this already. Left my phone unplugged overnight and lost 1% battery. If you're too impatient to take the time to do this, that's your loss. You'll see the battery life "improve" over the course of a few days as the reporting gets more and more accurate.
Sent from my Fascinate using the XDA app
I agree with supplysidejesus. This is a standard practice and should be done with each major rom or kernel install. This leak hasn't been put long enough for most of us to know what our expected battery life will be yet. Give it a few days for your phones to adjust.

Hi,
I just flashed SuperClean 2.9.2 (non-voodoo) yesterday, and I love the speed, but it really drains the battery pretty fast. For example, with minimal usage it drains from 100 to 82 in less than two hours. That's a lot worse than the stock settings I had on there before. Since I'm new at this, is that normal? If I switch to a better kernel would that fix it? Any suggestions on what to do or tweak?
Thanks!
[Update] 3/30/11
So after a full day of observation, I've noticed that it seems to go from 100 to 80 fairly quickly (less than 2 hours), but then the rate slows down. It took 4 hours to go from 80 to 62. Then last night I left it on all night, starting at 78 and it is now at 48 (almost 12 hours). Obviously I wasn't using it much overnight, but I wasn't using it much when the initial drain from 100 to 80 happened. Might just be that the meter is not consistent? But at least I know that it's not draining faster than the old setup.
Still looking into the idea of an undervolted kernel. Any good suggestions?
Thanks!
An undervolted kernel might help but who knows... if I get over 5 hours I usually consider myself lucky.
i updated this morning, have an extended battery, and seem to notice massive drains, but i guess with power comes sacrifices

Not sure why this double posted. Must have been my frustration waiting 5 minutes just to edit an already posted post to correct the name of the app....
Each phone reacts differently to ROMs / Kernels when it comes to battery life. Same setup shows different battery life for different people.
First I would use the "Spare Parts" app and see if you can find any app taking up a lot of your battery life and remove it. (included in SC ROMs)
People also report different battery life with different Kernels. You can flash different Kernels that work with your ROM to see if you can get better battery life.
You also may need to remap your battery. There are posts on how to do so. Basically you charge to 100%, shut down and wait for it to show 100% with power off, then boot, go into Terminal gain SU and type bstats. Phone will reboot. This should be done anytime you flash a new Kernel and some do it with ROM flashes too.
Also don't run screen at 100% bright, use auto or something at or less than 30% unless you are in sunlight.
When not in use turn off WiFi and GPS as well.
All I can think of right now

Running not even 2 hrs yet and mines at 70% right now from a full charge, so I feel your guys(gals)' pain. I checked with Spare Parts and noticed that under "Network Usage" there is a "0" that seems to be using up a LOT of juice. Searching it up on google brought me to a possible issue with GSM/CDMA (Time w/o signal issue). I remember issues with this with the D1 and the Eris, usually you could fix it on those phones by turning on Airplane Mode for a little while, then turning it back off.
EC10 is based off a GSM SGS phone if I'm not mistaken, and because of that may make the phone try to find a GSM signal. My time without signal was around 45% this morning so I dug around threads with similar issues with other phones brought me to this Hero CDMA thread: http://forum.xda-developers.com/showthread.php?t=651848 .
Now we do have the same menu as shown here: http://forum.xda-developers.com/wik...sung_Galaxy_S_Series&oldid=13336#Secret_Codes
My thing is that I can't access it using SC 2.9.2. It doesn't automatically go to any of the menus. Anyone else have an issue getting into any of the secret menus?
It also looks like turning the airplane mode on and off seems to work for now.

Read like 20 threads about the "0" and came to no conclusion haha. People just said it means root... and it could mean any app that requests Super User/Root permissions. Who knows though... I'm about to wipe date and reinstall afresh.
I'm really hitting a dead end with my phone recently. I flashed devoid froyo final with Franco's kernel v18 and have been getting horrible battery life. I'm not sure if I calibrated my battery correctly and I doubt its the rom or kernel at fault since everyone else is getting fantastic battery life. I have been using void echo until last month when I switched to the more updated roms of open optimus and devoid with Francos kernel since v12 i think.
I had great battery life with void echo but since moving up to the newer ones and newer kernel, its been horrible.
Can someone help me on what to do to properly calibrate my battery? And maybe on what app to use to find out the cause of the problem?

Charge your phone fully, calibrate battery using battery calibrate app, disconnect your phone, let it drain completely, then charge to 100% without pause.

With data on you will loose hell lot of battery either with FKv17 or FKv18....Desable data when u not need it..it will improve your battery strength.... And as suggested use full charge and discharge process to get every penny from battery.
probably install watchdog to check if some internet related app is draining your battery....uninstall those and watchdog after your work is done as wastchdog also consumes little battery....
flash void# forever i suggest...and wipe everything to start fresh....
hit the thanks button if i have helped you.
I charge to 100%, wipe batt stats from recovery, discharge to 0, take out batt, put on, try to on the phone for 3 times, then charge to 100% without using the phone
Battery Calibration
I've been doing the following steps after flashing new ROMs or if I just want to calibrate my battery:
1) Recharge the battery to 100%
2) Reboot into recovery without disconnecting the charger
3) Wipe battery stats
4) Reboot & wait until your phone is fully operational
5) Disconnect the charger
6) Use the phone as normal & let the battery drain to 0%
7) Recharge the battery to 100% preferably with the phone switched off
8) Disconnect the charger & use the phone as normal

Before you start doing this make sure you have time on your hands.
Follow it step by step...
Read the entire set of steps and comments first.
Do not deviate.
If you are having issue's with it not charging fully. "70% to 90% and no further." then begin at step 7
If you have Xrecovery installed wipe battery stats first to reset the battery cache to the defaults.
This post will not talk about apps or any odd mods.
It's here to clear up on how to properly optimize the battery in your phone.
The battery has a cache file used to set the top and bottom battery level.
Today i am gona teach you how to set it correctly using nothing more than your phone and charger.
While doing this it will also properly "cycle" the cells.
1. Charge your phone fully to 100%
2. Plug out your charger & switch off your phone.
3. Remove the battery and plug in the charger.
4. Re-insert your battery
This is sets the top end battery parameter to a higher state allowing for further charging.
Should read 88% now.
5. Keep a eye on your phone as it charges!!!
Remove the back plate and feel if it's getting hot "it should not be a issue"
6. Repeat steps 1 to 5
Repeat this no more than 2 to 5 times till the battery will not charge further
A few extra may be required...
The battery may get stuck at 70% to 99% "most of the time 88%"
The cells have now reached full potential
IF in the case that it keeps charging after the 5th time your battery is fully optimized Enjoy
7. Let your phone run down it's battery
Don't use the phone aggressively
Leave it till it switches itself off
Now it has marked the very lowest point of the cell in the cache
8. Don't leave the battery empty, begin charging as soon as possible.
If your phone does not switch on right away.. relax.
Just leave it on charge for about a hour "will switch itself on"
9. Repeat steps 7 and 8 a few times.
You will notice each time that the battery may charge just slightly bellow 100%
Getting closer to 100% each time
10.Soon it will read 100%
It has now marked the top charged point for the cells
If step 7&8 does not bring the battery to 100% use the battery calibration app from the market.
Don't rush.. take it calm and easy.

Battery drain can also cause due to some buggy apps that keep running in background, and taking lots of cpu usage during sleep.
If you are sure you have calibrated the battery correctly, and still facing problem with the drainage, I would suggest to try an app "systempanel" from market.(paid)
https://market.android.com/details?id=nextapp.systempanel.r1&feature=search_result
Keep the monitoring tool on for a day, this apps itself will consume few pinch of your battery for keep running in background, but once it generates the reports: you will know what apps are exactly using your phones CPU/Data/battery % etc which will help you to remove such buggy apps.
Hope it helps.

Keep the monitoring tool on for a day, this apps itself will consume few pinch of your battery for keep running in background, but once it generates the reports: you will know what apps are exactly using your phones CPU/Data/battery % etc which will help you to remove such buggy apps.
Hope it helps.

Hi there.
So I flashed Cyanogenmod7 to my Optimus One
I'm very happy with it, however, there's a problem
On official froyo and 2.3.3 official gingerbread, i had the data connection ON and wifi on,too.So whenever I left the house, it would switch to data.And it wasn't on 2g,it was on HSDPA. Anyway, the battery consumption was barely noticeable,especially in standby mode.
However, if i do the same thing now, on CM, the battery drain is enormous
Wifi does not consume a lot, but whenever it switches to mobile data, the battery consumption is 10% / HOUR in IDLE mode, using the Smartass governor 245-600MHz, making the phone useless. And this is the consumption in standby mode...when I use it it's a lot worse. This problem makes me unable to use the mobile internet without returning home with a dead phone.
Is there a fix for this? Does anyone have the same problem?
Yes, i have the latest version of CM7, for my model,p500. Is it because of the old baseband?
Thanks in advance for any help
i encountered this for the first few days when i flashed to CM7 too
battery drop so quickly even when its at standby mode for 8 straight hours.
but after using for weeks, the battery begun to last longer, can last up to 2 days with light usage (some texting and tweeting)
im getting minimum of 4 days battery on cm7 -.-
Try this
1. Charge your battery to 100 percent.
2. Reboot into recovery and wipe battery stats.
3. Completely discharge the phone till the state it switches off.
4. Charge again.
Maybe it will help.

I have never understood how or why this should work. Maybe somebody could elaborate this a bit?

@OP: Which CM7 version? What kernel?
This is not usual.
I'm getting few days with CM7. Try calibrating the battery with Battery Calibrator from the market.
I already calibrated with the app from the Market
Charged to 100% ,Calibrated,discharged to 0%,then fully charged.
I did this twice.i dont think this is the problem.
I did a test :
Yesterday,when I first saw the problem,i had data enabled.I got 10 hours of battery life with the phone Idle (locked,yes.)
Today, i didn't enable data.I had 99% battery after 2 hours of idling. I guess that's normal.
So, i already know the problem. the data connection does this to the battery,but why?... as i said,when I was using the official froyo and gingerbread,i had both data and wifi enabled and i had absolutely no problem with battery drain...

This is called battery calibration.Whenever u flash a new rom,u need to calibrate ur battery so that it wont show u the stats of ur previous rom.If u dont wipe battery stats,sometimes the phone may switch off fue to low power at 15-20% or strange things like virtual increase in battery % by 2-3 %.So it is required to wipe battery stats,so after booting the phone,a new battery stats file is created and it wont give false info.

There's no need to completely discharge a Li-ion battery, it can in fact damage the battery.
Proper steps:
1. Charge your battery to 100 percent.
2. With phone still plugged in, reboot into recovery and wipe battery stats.
3. Reboot phone
4. Wait for phone to completely boot up then unplug.
5. Calibration complete

Hmm.. that's unusual. By the way, 6.6.1 or 6.5.8? And also specify the kernel you're using.

flash newest goldenleaf kernel; -> http://forum.xda-developers.com/showthread.php?t=1227682
disable gps;
disable wifi;
set interactiveX as default governor;
set minimum brightness;
disable data;
use 2g instead of 3g;
disable bluetooth;
make sure that your installed apps aren't killing you battery (via android config/view battery status);
reboot phone could help sometimes.
ps. the new baseband consumes even more battery

wait....better signal=more battery consumed?
New baseband for me is lesser in battery consumption than in old baseband

Wait !!!!!if its only bcos of data i have a solution!its because unwanted apps n process use data n consume charge ..so go to market --download droidwall ..and manage apps tmwhich you require connectivity for
Trust me it sounds silly but you ll surely see much improved results! !

I checked for apps that consume internet.I don't have any.Facebook would be one,but that's all.
I read something about the older versions (official ones) of the firmware using something called NETMGRD to reduce the battery drain caused by the APN being on..
what do you guys think about this?
And also,since you asked about the kernel :
2.6.32.42-franco.kernel.v18
Cyanogenmod 6.5.8
If i use 2g continously i get batrey lyf of 3.5 hrs..
Is this normal?

im not sure but according my exoerience even the android sytem sometimes uses internet..
once when i checked my battery usage is saw something names MEDIA SERVER poping up!havent seen that before and i was having say 5%battery darin in 10 minutes with screen off and wifi connected n active!!so then i got droidwall and blocked everything except for ones that i needed like market,xda,browser etc!and i saw that thing named media server go down n my battery lasted longer..had about 1-2 %drain with 3g active and screen off!else it usually will be higher!

That's pretty outdated kernel. Flash a new one.
I get good battery life using the 2x Battery program that cuts off the 3G data when the screen is off and opens it at a set time (every 30 mins on mine) to check for email etc instead of constantly when the screen is off.
One of your major killers i see is the constant WiFi, with it and GPS if your not actively using them turn them off.

Forgot to add, the rule of thumb is anything that uses a hardware component uses battery power.
GPS
Wifi
Cell Radio (2g,3g,Phone)
Screen
Vibrate motor
Speaker
It takes power to make those work so the less you use some of them the longer the battery lasts.
Anyone that drives at night knows the effect of turning on the wipers, the radio, the lights and the blower fan on high to clear off the windshield and seeing the voltage gauge lowering from the heavy voltage draw.
