Default Cyanogenmod = Horrbile Battery life

Well I finally made the switch to 2.1 and am runnning the cyanogenmod 5.3. For about 2 days, it seems like I am getting worse battery life then I did on my 2.01 rom. I only have the facebook and beautiful widgets running, I have also tried disabling them. I have disabled live wall papers and have also updated to the latest baseband to see if that helps. In settings the biggest culprit is display and cell stand by. I use the medium setting on the power widget for my brightness so I am not sure what else to do. Btw, I'm at about 40% on 6 hours of ligbht texting. Is this normal, and anything I can do to help with this? Thanks again!

40% after 6 HOURS AND YOU'RE BITCHING? I am a hardcore user, and im at 40% on my n1 after pounding it all the way to work on my commute(2hours). Buy a second battery if you have a problem with REALISTIC battery thresholds that current tech is able to provide...or buy a damn razor...cause smart phones SUCK BATTERY!

n1, CM 5.0.5.3, 2 BATTERY!

You are doing fine. Try experimenting with a few different kernels (see if the low voltage kernels work for you) and different profile settings in SetCPU. I use Quick Profiles to turn off bluetooth and wifi, and adjust screen brightness depending on my current situation. All in all, 40% after 6 hours is not bad but can get better with some experimentation (and will continue to improve with the developers constantly tweaking ROMs and kernels). I keep my USB charger handy at work and if it is going to be a long day keep my phone plugged in in my car just to top things off.

40% after 6 hours seems rough. I have live wallpapers, plenty of widgets, and light usage (texting mostly) and I'm at 70% after about 24 hours.

Bout to update the baseband. Hope it helps with the reception in the basement. Bleh.

for cell standby are you seeing the 50% Signal loss in the Cell Standby details? that could be causing the battery to drain faster

I would try a new kernel and if you are still having issues then I would try a fresh install of CM.

I never realized you could click the specific battery drains for more information. Neat.

The cell standby reading in the ROM is evidently inaccurate...you can actually turn airplane mode on and then off again for it to read properly. Worked for me.

I have a friend who is at 70% after a full day of use...I'm more like at 40% after a work day. Never been able to figure out why - he uses more stuff than I do, it seems...his phone is just better at battery use. Could partly be he has a much stronger signal at work than I do, and if the phone has to hunt for a signal it eats battery...

yeah, pseudo fix

Turn on Airplane mode.. then wait a minute and turn it off.

I read somewhere that there is another set of steps, that has you plug in the phone, make it sleep then unplug then turn off airplane mode

From what I have read the crazy signal loss percentages are more of a reporting error than actual battery drain and not really anything to worry about. This has been an issue for a while. Also, how is everyone reporting there battery usage percentage? Programs that reported estimated battery life (like Battery Left) vary significantly from direct objective system readings.

Settle down there.

I'm running a low voltage kernel at 1,000 MHz and I can go 12 hours of decent usage and only use 50%.

Do you stream pandora and stuff all day?

I'm about dead after 13 hours - and I don't use the phone much other than to text and read email. Battery Left says about 17 hours start to finish. I AM OC'd at 1.2ghz, however. A buddy of mine, totally stock, can go 35 hours on a charge, which makes me a little angry

I had bad battery life as well until I updated to 5.0.5.4....my phone has been off charge since 7am EST and I still have 70% battery left. Mind you I don't use my phone much, but still it has increased tremendously throughout the updates.

From what I've read, if you have high standby as well as high signal loss you may have a "real" problem that is costing you battery life...as opposed to a simple problem w/mis-reporting of standby...

See this thread for more info and arguing:

anyone worrying about the Cell standby loss, but wanting to keep cyanogenmod, I would suggest trying JRummy's CM 5.0.5.7 Themed ROM...

I have not really worried with the whole cell standby battery issue, but when I switched over to JRummy's ROM it has gone away completely...

I did not try Koush's 5.0.5.7, so it may have been fixed by his latest update, but I know for a fact that cell standby loss doesn't exist on the JRummy ROM....

copied and pasted from a post i just made in jrummy's thread on the cyanogenmod forums:

today i finally had an 8 hour work day so i had some time to let the phone sit idle to test out this issue. i took the phone off of the charger at 8:15 this morning and after 8.25 hours of idle time it was still at 80%. right when i left work i had a quick 2 minute phone call and then on my 15 minute ride home i played some music with the rhapsody app with the screen on. when i got home, so just under 9 hours since it was taken off of the charger, my battery showed 70%. other than the 15 minutes of playing music with the screen on, the quick 2 minute phone call, and me pulling it out of my pocket to check the time every so often, all other usage was the phone sitting idle.

about mid morning i checked battery usage and it showed time without a signal being 50% under cell standby. i quickly put the phone in airplane mode and quickly took it back out of airplane mode. i checked it again maybe a half hour later and time without signal then showed 0%. so there is definitely some kind of bug or glitch going on there but it doesn't actually seem to be consuming battery. i guess the only question is whether me quickly toggling airplane mode on and then back off midway through the morning had any actual effect on battery or just had an effect on the percentage that was being displayed.

either way, battery life has been good. also with bekits 1.0ghz lv kernel the phone seems to run pretty cool and fast.

I'm on P3Droid's 7-slot 900MHz...

I get bad battery life in general at work, where we have a poor signal. At home w/the phone off charger at 7AM, I'm at 70% at 4:30PM. A key issue, IMHO, is that I get a good 3G signal at home, so the phone doesn't hunt for 3G constantly like it does at work. I've used it for calls, some texts, and hour streaming a podcast, marketplace stuff (adding an app), some email, used wireless for about 20 minutes, and IRRC I made a nandroid backup of my current ROM earlier this AM.

Can everyone cite their battery life in: hours to dead.

The kernel they are using and what their basic SetCPU setting is: i.e., 550/1000.

Use would be based on the amount of hours of continuous use, web surfing, etc per day:

Light: 1-2 hours, Moderate: 2-4 hours, Heavy use 4+ hours .

The only thing I have noticed was that my CPU heats up faster then with BB but I just think thats the Kernel. My Batt seems to be about the same.

for everyone having this battery issue, can you check under Settings > About Phone > System Updates to see if there is something there?

just wondering because i had a huge battery drain issue due to the fact that my phone kept trying to download and redownload the 2.1 OTA update. for some reason, BB0.9 didn't block the OTA but instead removed a file that caused the OTA to keep downloading over and over again. phone heated up and battery life kept dropping even when phone was mostly on standy throughout the day.

The Cyanogen roms do not have the Sytem Updates option at all. Koush took it out of the code completely... So there is no way to check if there is an OTA update. If you are running Cyanogen though you should not be getting the update at all...

weird. seems like only some people have that problem then. i know not everyone had it for some weird reason. but otacerts was removed completely and this caused the 2.1 OTA to keep dling over and over. after downloading otacerts from another forum and putting it in the appropriate dir and allowing the update to "install", the problem went away. so i dunno. just a suggestion because i thought BB was supposed to block OTA updates too but i had the problem anyway.

I'm running the newest cyanogenmod and a low voltage 1ghz kernel @ 800mhz. Battery life since I made the switch the past 2 days has been pretty good. Moderate usage and was at 50% when I went to bed last night. Pretty good if you ask me. And my cell standby has been 23% of battery usage. Time without cell signal is at 50%. But that can't be right.

right now i am running jrummy's latest rom with no success. i just updated and so far i am not impressed when it comes to battery life. i took my phone off the charger last night at 100% and made sure no tasks were running in the backround. made sure my screen was off and i put it on my night stand. i just woke up and my battery is at 80% by just idleing! i went to battery use and call that 51% is cell standby. i will try again tonight with the airplane mode fix but i swear i have done that several times...

Wait how much time was it off the charger? Cause if it was the whole night (8 hours) and you are still at 80% that is pretty good... Even if the phone is idleing there are still processes that will start and stop.

As far as the 51% cell standby issue, everything that I have seen has shown that this is a weird bug that happens to all Droids rooted or not. There are different variations of it as well, What does it say for "Time On" and what percentange of the battery is it showing it used (not the standby percentage but the actual battery used)? My understanding is that the bug that most people are seeing is a display issue and it will show the Time On as double what it should be. This does not drain the battery and is what most people have, the one that actually drains the battery is very rare.

It was prob off the charger for about 6 - 7 hours. I will leave it plugged in all night and see if that makes a difference tomorrow morning.

Update: I decided to try Cyanogenmod V5.0.6.2 with Smoked Glass-Esque V1.5.1 and I couldnt be happier! Best battery life i think i have ever had with my phone with moderate to heavy usage today. I have had it off the charger since 6 this morning and did alot of texting, picture and video recording, and just plugged it in with 20% left! Looks might I may be staying on this one for some time [:

Here is my experience.

I was haveing bad battery life with CM 5.0.6.2 and all previous versions, so I did as someone suggested and turned off the percentage battery indicator. I also changed back to the stock home in RomManager.

Prior to those changes, under settings > about Phone > Battery Use it was always showing Mediaserver taking up a large portion of battery used. Well for the last several days Mediaserver has not been running at all and my battery life has been GREAT.

I don't know why Mediaserver was running before, as I had no media running. I do not listen to anything on my phone. or play games.

I hope this helps someone.
