Hey guys, I am on cm 7 nightly #11. I am on radio 09.01 and have experimented with Chad's and the stock kernel.
I have background data, auto-sync, wifi, bluetooth, gps all off. I dont have facebook or anything pushing either. Screen brightness is on about 60%.
With the seido 1750 mah battery, I am getting around 7-8 hours of battery. That is to the bone dead .
That is making maybe 1 call a day, a couple dozen texts, browsing the web a bit and listening to an hour or so of music/pandora.
In spare parts it says under 'other usage'. Running 42.7%, screen on 23.8%. 'Partial wake' only ones on here are really music and pandora, but they are relatively small slivers.
Under settings it is 68% display, 8% cell standby, 7% voicecalls, 4% android, 4% idle.
I have tried wiping battery stats, doing the drain all the way technique, etc.
Anyone have any suggestion on what to do here?
Thanks.
I'h suggest moving to Cymod 7 RC1 (unless you mean the new nightly, then I'm not sure) I have been running cyanogenmod since before the nightlies hit and I've never had battery that bad. I get about 3 days of standby out of my phone on RC1 and the incredikernel. I listen to pandora on 3G (charging only in that time) about an hour a day and never charge otherwise unless I'm using it heavily. I text semi often, but don't really listen to music or call.
Seems wildly different that my experience. I take it this is specific to this rom, and your battery is better on others, ie battery itself not going south? With pretty similar usage and syncs to yours, I make it about 10 hours to use 50% of batt while at work. That's with stock battery. Only new nightly #8 with stock cm7 kernel.
1) change to 2.15 radio
2) did you buy the battery off ebay for $10? If so its really a 1250mAh or so. Either way OEM batteries are better than the aftermarket (ie Siedio)
3) Is the battery really old? If so it may be wearing down
4) Kernels are all decent, they should all get better than what you are getting...
5) Don't overclock to 1300+ it should run smooth at 998 or whatever it is.
I get 12+ hours of moderate use out of my OEM 1500mAh battery.
When I first started on the nightlies and flashing different kernels, I was having the same issue.
I stopped flashing other kernels and started using the stock cm7 kernel, now I am getting awesome battery life. Also, after flashing, several people recommend immediate rebooting to improve battery life.
Thanks guys.
Few questions.
1.) Radio 2.15? I am on 2.15.00.09.01 currently. Is that the same?
2.) Mine is an authentic Seido. But should I start using the OEM 1300mah battery?
Oh, I should mention. I don't overclock at all.
I was using the stock battery and got ~6 hours even with UC to ~850 most of the time and ~200 while screen off. Turns out my battery was defective and even now OCing to ~1100 most of the time I'm getting 4x the battery. Of course I couldn't be sure that my battery was defective until after I bought the new one but if the battery life just doesn't make sense then you might want to try going back to stock (assuming that's fine) and comparing.
try a different battery maybe
i currently have the stock battery which was only used a couple days
a HTC 1500 battery
a seido 1750 battery but i havent tried any of the other batteries in awhile but i also use CM7 nightlies on #11 because it seems to have best battery life
maybe ill try my other battiers and see my findings
I've had a similar experience and I'm fairly certain it was not my battery. The battery worked great with other ROM's; Normal usage of my phone would yield roughly 40% remaining battery life at the end of the day.
After going to CM7 (I started at #38) my battery has been lousy. I can't get through a day at all.
Two days ago I flashed incredikernel 2272011 as well as CM7 build #11. I'm using the default smartass governor and my battery performance is back where it used to be. Going through an entire day for me is no problem with normal usage.
Not sure if that helps but I've had good luck with this kernel thus far. Oh... and phone has been rock solid!
I'm on CM7 Nightly 11 right now with stock kernel. Seidio 1750 that I've had since last June. I've recently been comparing Tiamat's 3.14 to stock. If I'm on any kernel that has Smartass I'll use that as my governor. If I'm on the stock kernel then I use SetCPU with the kernel set to ondemand and a screen off profile set to 245. Either scenario seems to give me pretty good battery life, but I think Tiamat's with smartass may be a little better. With any kernel I've had it overclocked to 1.03.
Also, the brightness settings based off of HTC's ROM that were posted in the cm nightly thread in the development section have worked great. I've definitely noticed an increase in battery life.
I use advanced task manager with the shortcut on the desktop. I leave essentials running in the background but try to make sure everything else is killed.
All in all with the current setup I have I can get roughly 12-14 hours with heavy texting, 4-5 phone calls, internet and games scattered throughout the day.
I found this thread on Desize HD forum:
http://forum.xda-developers.com/showthread.php?t=984337&page=6
then i wonder can we get some information to know where the problem come from?=> we can fix the battery drain issue on all GB build. Hope it help out devs. cheer
Sorry for my bad english
What drain?
Are there really so many problems with drainage on CM7/GB builds?
2d, 3h, 25m on battery with 60% left.
The first CM7 build i used is the one in my sig. I'm amazed by the lack of problems with this build
The only drain that's still ongoing is bluetooth on standby drain AFAIK. This DSP issue is not related to the HD2, thus I don't think it's valid to implement. With bluetooth turned off and heavy usage, I get roughly 2 days out of my device also... I really don't think the drain is a big issue. Honestly, the biggest issues is (And it's not much): Robot voice once in a while, some Wifi issues (EAP mostly), Wakeup lag and BT drain on standby.
the drain is related to the toolchain used to compile our kernals and roms?). I however can do easily 3 days with out charging on android, using the same setup as KrewsialNL
Actually
Actually, i get pretty horrible battery life across all builds...
it could be that I have a v1 TMOUS hd2 though... something is weird with it. I always get random energy spikes (even with sync off)
can't get more than 14-18 hours...
My battery drainage is fine using the Typhoon rom. I think some people are expecting a little too much out of their batteries.
It's only 1230mah if it was 1500mah it would have been way better.

How on EARTH are you getting that long out of your battery?
Are you using the phone at all?
I've used loads of different builds and never come even close to half that battery life, in fact no more than about 20hours MAX with light usage.
I am using Juice Defender to disable my WiFi and Data when the phone is not in use too.
Any tips?
I have run all the latest GB builds and I also get this weird spike (around 70mA to 100mA) usually when I leave the phone overnight (not charging) and this drains my battery down to almost empty by morning. This is with bluetooth off and wifi on. No apps installed on the phone.

mmmm That CM7 build has great battery life but yours is beyond reality... are you sure you haven't connect the phone in those 2 days?
Mine says "4D 10h 1m 50s on battery" and has more than 50% left but it has 3 green spikes (in battery use, I connected 3 times but didnt charge to 100%)

Well I was going to say exactly EXACTLY the same thing! Except that i didn't like Juice Defender
Is battery THAT GOOD?!?
Battery
well yes, it's certainly feasible...
it's just that MY hd2 specifically gets random spikes in energy usage.... I'm not sure why, been trying to resolve it for a while.
I don't really get those spikes in WM, only when I go someplace that doesn't have signal... it will spike up initially and then settle down (dutty's rom)
However, with these android roms.... i get random spikes of increased current around 100-200ma while the phone is in sleep. Bluetooth off, sync off, wifi off etc.
also, when the phone is in use... it is not uncommon to have current of 400+ consumption... hitting 500+ when web browsing...
I never got this high in windows mobile...generally around 400 when streaming youtube in wm. I'm wondering if it is an android thing...
edit:
in a perfect world, our battery consumption should stay around 4ma constantly... Which we know that isn't always the case because we have data syncing and signal strength changing...but to give you an idea....
if we have a 1230mah battery... dividing that by the current draw (4ma) gives us a standby time of ~307.5h....
that's ~12.8 days
however, with my current usage... say, i'm getting about 14 hours out of my battery... that's like if i constantly had a current draw of ~68ma...
Taking a look of my usage charts.... if we say the phone is only in use for 6 hours, and the rest is in standby for 10h at 4ma...
the 6 hours would have a power consumption of ~300ma the whole time....
which i think is kinda excessive....
meh. i don't know.
perhaps i'll upload my usage charts later... lately on this new rom, i've been getting only 8 hours of battery :/
but it could be because i've been playing around with it too much
I am on a TMO US HD2 first generation and I am doing good if I can get 6 hrs of battery with the stock battery and normal usage. No wifi, 3/4g, no GPS, and auto screen dim. If I am using the net or something like angry birds I am down to 2-3 hrs max. I have tried underclocking and still not getting a full 8 hrs of life. Would love to find a solid rom that lasts 12 hrs or more. Ordered an extended battery so maybe that will help a bit.

Define what's good and what bad with the standard battery? I have been getting on average about 10-15 hours and that's with doing alot of texting, web surfing, mp3 player and xda lol, and crunchyroll (streaming shows) usually over 3g but sometimes over 4g.

Thanks for the tip. I have a second HD2 that I test builds on and I was actually in the process of installing the ROM you mentioned last night I am excited that this may be the rom to drop on my daily driver I have noticed that non GB roms (2.2) seem to have much stronger WIFI signal strength so I am hopeful this GB version will have solid WIFI signal too. Love using GB but hate the wifi issues I keep having. Thanks agian for the tip.
Well, this thread didn't go anywhere.
I'm finally trying to get up the courage to switch to a NAND rom.
I get awful battery life out of my SD build I've been playing with and that is with a 1500mAh replacement battery.
I'd hate to switch only to find myself in the same position?

battery drain on SD builds may vary from SD card used.
I can confirm that from my experience, i was not able to use the phone on the second day (total up time 1d + 12h TOP) when i was on SD builds
BUT.. while on NAND (no A2SD no Data2SD)
I can confirm that i can now use the phone for 2d + some hours, depending on use.
All battery info apps told me that battery life is Good (not excellent, not very good).
Made the switch. Battery life as good if not better than with WM and SD build. I feel the biggest improvement came when I installed setCPU.

is a 14 - 15 hours a day a good battery life?
all i do is send text about 150-175 sms a day.
from 8am to 12am then i charge but still about 20-30% of battery life left.
thanks. sorry for my bad english though.
Not to bad but could be better if sll ur doing is sending texts. Do you have set profiles in set cpu?

I think i have one. I think when it is off screen I have set it with 245/245 only. I dont know how to use well setCpu until now. yesterday i OC'ed it to 1ghz with the same result.
Think you can help with some settings with it to better improve my battery life?
I also use the .26 radio. .27 drains my battery alot.

screen brightness is gonna kill your battery.
i send a good 100-150 messages between sms and google talk a day, browse a few pages, check xda, a few calls, 10 pix a day, wifi on all the time even when not home, and ondemand governor 1209max 368min and with a 830am start to a 10-11pm recharge time i would have 30% battery left. today i didnt quite use it as much, and im at 62% right now, and its 915pm and i took it off today a little late at 9am. so 12 hours and 38% loss is not bad (cm7 nightly 31)
i do not even have setcpu installed anymore, that was actually slowing my phone down. im using the AUS radio again and its working good now with that ril update, and im using a 1500mah battery, which isnt much over stock but im gonna go to the stock battery and see how that goes to get a bettery battery life/accuracy on a stock battery to see how it does. not that this battery has given me any troubles, but im not a fan of some aftermarket stuff.
The best Battery You will get is with the Miui Rom. You will loose Sense. I did purchase the Red Battery and It is Very Good
for the screen brightness i use 30%
so what tips can you share to even improve my battery life? thanks

Do you have flip to silence enabled? That killed my battery since i unchecked that feature been great since.
Im at 67% now. Off charge for 12 hours now, but i did plug it into the computer for 15 minutes to get pix off of it. SO realistically id be at 60 or so.
I would be going thru your settings and your battery stats to see whats really killing your battery.

Really? That's a bit weird.
I have it enabled and don't seem to have particularly bad battery life, although I am a light user, so my phone is just on standby most of the time.
The amount of time your screen is on will have a big impact on battery life (even with the brightness turned down). So even though SMS itself is not a big battery drain, if you have the screen on often, and for long periods while texting back and forth, that may be the culprit.
I notice an instant drain when screen is on. Ill be going down slowly at say 90 for a few hours, but will drop to 70 within 30 min if screen is on whole time
sent from the rooty tooty fresh and fruity cm7 nighly powered G2
nope dont have that flip to silence.
How's your signal? At my home (ironically) I get terrible 3G, so I switch to Edge and my battery life does a lot better. If sms is all you really do, you don't need to be on 3G. I only switch it back when I go out where I have better signal.
Of course this only really makes a difference if you're in an area with bad signal.
I got 3 profiles set with SetCpu
screen off "246 min - 768 max" powersaver
< 15% battery " 246 min - 768 max" ondemand
charging "246 min - 1209 max" performance
and my main is "246 min - 1209 max" interactive
I'm running whatsapp, 2 pushmail accounts (contacts, mail and calendar), 2 pop mail (1 hour autopoll), facebook (15 min autopoll) and then about 50 texts /day + some calling. I can get up to 14 hours max... but indeed the screen is killing the battery.
Also at work I got bad reception (gprs only and sometimes 3g/E but very poor). When I'm athome I get full 3g/hsdpa and the battery will last much longer.
I ended day yesterday with 33% battery. I also was on the phone for 3 hours. Prior to phone calls in eve, i was at 67%

Screen brightness. Turn off 3g, or other services..
And if you want better battery then buy a bigger one. The stock battery imo sucks.. the red chichi battery is what I got. Cheap, came with 2. Work great.
I also use fast reboot to kill any apps that may be running in the background that I don't want to, I.e. browswer, maps, facebook..

thanks for all the reply. i will surely remember this to further improve my battery. i have never used an Edge connection at my place. btw i do not live in the US. i live in Philippines.
for the radio's what do you prefer using?
is it the .27 Aus radio or the .26 radio? thanks. i use .26 radio at the moment and it gives me nice performance of one time about a day with medium to heavy texting with half an hour of games. but one thing, when i was on a mall with free wifi service, i could easily connect to it sense / gb CM roms (i think it's the original radio but could not recall it anymore). But after updating to .26 radio bout 4 or 5 weeks ago i guess, i can't connect to their wifi connection anymore. But weird i can connect to my own connection at home. Hope you can give me advise before I change the radio tomorrow i guess to see if the problem in connecting to the wifi service in a mall at our place could be solved. and sorry for some bad english.
I have a 2800mah yoobao battery and its only lasting me about 18-20 hours...but a guy on youtube shows hes easily getting 2-3 days on his phone. I moderately use this phone with black backround...wifi enabled gps bluetooth and everything else i can disabled...and i have app killer and juice defender why is this battery not lasting long
Well first those ebay 2800mah batterys are more like 2100-2500mah. Second that guy on youtube did some black screen tricks and some other things to get 3 days. I wouldnt use any app managment programs unless you have 10 things that want to startup,and juice defender just isnt a good way to save battery unless you always have a bad signal,when you have a great signal very little battery life is used by the radio.
But I just posted some great numbers using the seido 3300mah battery,and I actually used this phone plenty during the tests...

Like ecooce mentioned, those batteries aren't generally as good as they claim. But I can't answer your question until you answer a few more to the best of you ability:
1. Are you using a ROM? What ROM?
2. The "guy" on youtube was definitely using a ROM, what ROM was he using?
3. How long does your phone last on your stock Samsung 1500 mah battery, for reference?
4. How many and which widgets do you use?
5. Do you have poor signal and frequent roaming? Do you use Roam Control to rectify the constant signal searching?
6. Is your task killer an auto killer?
Answer me, and I'll answer you
well im not using a rom... i want to try to find the best rom for a extended battery. and i dont use any widgets just a clock one. i get about 10-12 hours on the regular battery if im lucky...im gettin about 18-20 on this one...i jus think i could get more

OK, this is simple math...1500mAh battery is stock, you get 10-12 hours. 2800 mAh battery is only 87% higher which equals 18-20 hours. This is only true if it is a true 2800 mAh battery...so count your blessings.

Well you can try the Syndicate Rom Frozen I'm on, it's referenced in my signature. Only use your task killer manually. On auto-kill it will use battery to constantly run, and will kill services which immediately restart anyway. I use Advanced Task Killer manually by its widget, which, combined with my Power Control widget, are the only two widgets I have confirmed are not battery drains. This includes Pandora, Music player, Wifi Tether , Tesla Flashlight, and ES Task Manager widgets.
Moving on, Low brightness when possible, Google Sync off, unnecessary apps found to be running in the background removed. Google Wifi and GPS locations off, you want none of that. DRM and SNS services frozen by Titanium Pro or MyBackup Pro if unneeded (yes those apps are not free, but worth it!). Mostly black wallpapers use less power due to the nature of Super AMOLED screens (the pixels are effectively off when black). Do not use Juice Defender. VisionKernel 1.1 may be helpful. Do not use setcpu, stick with the Dev's stock settings, I'm sure you'll be happy :-D.
If I think of any major steps I've taken that I'm forgetting I'll be back lol. I think I may end up making a new thread on this with a list of my steps and setup.

Well I'm that guy on youtube abd I believe I at that time I was on syadicateROM Froyo with a 1.3Mhz OC'd Kernal...now what saves on most of my battery life is underclocking while the screen is off to a max speed of only 600mhz...since about 75% of the time your screen is off...those numbers were for about the 1st 3 months with the battery....now I'm averaging from at least 30 hours to around 50 sometimes 60...but no more 3+ day stretches...and I make sure to condition my battery on a regular basis...because I did go through a major sump in performance jut like you are with around only 18 or so hours...a few (like 3) calibrations got me right back up to where I was at with hours unplugged....I think I talked about this in one of my video's...hope this helps fellas

When I switched to ec05, my battery life went to crap. I now have the yoobao 2800 and with syndicate frozen and a few tweaks I now get around 24 hours moderate to heavy usage. 48 hours or more with light/idle usage.
On the other hand I'm lucky to get 8 hours out of my stock battery with light usage. I can literally sit and watch the srf battery meter draining every minute the screen is on. I'm thinking my stock battery may have gone bad.
The extended battery makes my phone huge. But theres nothing better than being at a conference talking on the phone constantly and still having 30% left at the end of the evening. While all the other evo's n blackberries n such are crying that their phones are dying by happy hour...
I'm not a heavy user, but I regularly get 30+ hours with 2.5 - 3 hours of screen on time off of a 1500MAH battery using SRF frozen.
You could have one of several issues:
1. Gallery app sensor issue.
2. Airplane toggle issue
3. phone not sleeping properly.
Any of them can severely impact battery life. If you look at your screen on time and you are regualrly at 2-3 hours screen on time in 12 hours then that is about right I would say.
I am a light to medium user and I get 40-55 hours of life out of my extended grant you my back ground is mostly black. Only widget I run is sense analog glass clock which pulls the weather every 15 minutes, I have task killer auto kill on, set cpu set to ondemand 10000 and 1000 which I believe is stock I was playing with it for a few still am (I just modified this to 13000 - 1000 set to performance so stay tuned for a update), Avg, wifi is usually on i forget to shut it off and gps is always on. I am using Frozen 1.1 with Vision kernal 1.1. Hope this helps. Don't forget to calibrate your battery I found that it does help to let it drain fully once after the calibration.
**********************************
Update well I have been testing since I first posted I am now getting about 18-24 hours but my usage has gone way up to high like 200 to 400 txt a day plus now using winamp cuz my music player died. Playing music for over 2 hours a day also poor signal strength at home so always have wifi on. Not sure what modem I am using not sure how to find that out either. Also my Setcpu is set to 1300 - 100 ondemand it didn't like having any other setting. I also turned journaling on which might not help the battery life.
EC05 suck your battery? Flash the EB13 modem. http://k0nane.info/rom/acs-eb13-modem.tar
I have this same battery and I have google and AOL email syncing every 30minutes, brightness on full, 6-7 widgets, 3 of which run constantly, and usually have pandora running most of the day, spotty signal, and data on all day...
I get 52-58 hours every charge with all this running, and an average of 4-6hours screen on time...
Also, when I put it on the charger i never let my battery get below 12% usually it goes back on after 55hours @ 16-21% left
Maybe I am lucky?
Running AOSP rom
ur lucky...cuz i have had this battery for about 2 weeks now and im starting to get about 24-26 hours of life...maybe the battery needs to be broken in cuz its increasing
I've been using CyanogenMOD 7 and love it (mostly). The one thing I don’t like about it is the short battery life. I'm kind of new to rooting phones so it took me a bit to get it rooted and get CM7 rolling. I was wondering if there are any mods out there like CM7 that have better battery life? Or if there's any thing I can add to CM7 to give it more batter life?
I've been using android since the first phone came out so I’m already knowledgeable in what to turn off to try and extend the battery life, but I have noticed a big decrees in batter since installing CM7.
Thanks for the help guys

You can under clock the processor when your phone is asleep. This creates better battery life.

Have you tried wiping battery stats?

your phone automatically underclocks your processor when it sleeps (for most CPU governors), you do not need to tell it to do so.
I'm not picking on you fyi, I'm just making sure we are giving people accurate information... there's only one thing worse than no information: incorrect/incomplete information.
op: which version of CM7 are you running? remember, the more minimal your setup (ie less homescreens, less widgets, manual syncing of gmail and whatever else, etc) the better your battery life will be. this is especially true of newer phones that are getting heftier cpu & gpus that, while intelligent with power consumption, are going to drain even larger capacity batteries relatively quick with moderate/heavy usage.
how long are we talking with battery life? how heavy a user are you? for reference, I get around 16 hours of battery life if I don't charge the phone at all from unplugging to battery dying with moderate to heavy usage (texting ~50 times a day, sometimes up to 100 emails depending on what's happening at work, couple hours of calls, couple hours of streaming music [pandora or audiogalaxy], couple of hours of games [peggle and plants v zombies mostly - both of which are resource hogs], etc).
I have just learned to get used to the fact that the phone is going to die if I use it a lot, so I've purchased three micro-usb cables and a car charger.. that way, unless I'm in an area where there is no charge-capable usb port nearby, I'm always able to get a little more juice if need be.

but i also mean setting the max sleep to 368mhz. by default its set at 800mhz. sometimes with apps running in the background, the processor may go to 800mhz without you knowing
check out 'powersave' and set your cpu max to 806mhz. should last you a nice long time like that. responsiveness suffers, of course.
'ondemand' and 806mhz is the best comprimise for me. still fine with HDvideo recording, streaming audio, Nav, etc
if you really want to make it last... clock down to 400mhz, turn off all the sync, set brightness and timeout to minimum, all the radios off (airplane mode), and the volume down, on vibrate.

But some govenors don't drop the sleep to the lowest profile. In fact almost all keep it above the lowest clock. Other kernels allow it and you can also use third party to set it lower. When the tweaKr script becomes universal it will be even better =)

It suffers in powersave because it stays at the lowest setting only. No reason to set to 806. Lol and that bottom comment is hella funny =), but if he does that his phone will just be...a waste of pocket space.
Your best bet is to do some research on kernels. If you are using cm7 to cm 7.0.3 id recommened pyros kernel. If you are on 7.1 or a nightly over 121 I believe id go with eugene's streamline5. It did wonders for mine Also there is a battery saving tips. Google G2 battery saving tips. Should be first link that comes up.
Cyanogenmod roms are known to be battery hungry. Nom nom nom.

I used the battery califration app if that's what you mean.
Thanks for all the help guys, i'll check out some Kernals.

Do you have link for this? I'm running 7.0.3.. but I dont think im finding the correct Kernal.
Mugen 3600mah = better battery life...
Can you elaborate on what kind of battery life you are getting now? How many hours, and for what level of usage?
How long have you been on CM? It takes a couple charge cycles of the battery after flash any ROM, for the battery meter to be accurate. Clear battery stats (as mentioned) then charge to 100%, let drain to about 20%, repeat a couple times. Don't drain until the phone dies. Some people say to do this, and its not good advice. Over discharge of Li ion batteries can cause them to no longer take a charge. There are people on here, on the Vision and other phones, that let their battery drain to empty, then the phone would no longer boot, forcing them to replace the battery.

It has good battery life but the battery sticks out a lot and its very uncomfortable
