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.

Hello all,
A few months ago I became a proud owner of a Moto Defy, a great rugged phone that has been working great for me until just last week. For some reason the battery life was cut drastically! So bad that while the screen was off and not touched at all, the battery percentage would go from 100% to 40% in four hours.
what was even worse was when I would connect the charger, the phone would charge completely in less that 1 hour! I didn't seem to matter if I was browsing the web, playing music over the loud speaker, or just leaving it alone, the battery seemed to fall the same.
I began to research online for some answers since I couldn't believe that the battery would just go bad just like that! first I installed a custom recovery that had the option of wiping the battery stats, but that didn't work. then I stumbled across this thread on a battery bug in the android os 2.3.
http://forum.xda-developers.com/showthread.php?t=1039696
Even though the os on this defy is 2.2.1 I thought I was on to something. they talked about an app called watchdog. I also found an app called Battery monitor widget, which allowed me to see the battery usage in milli-amps.
I got concerned when during the day, I noticed a spike in the battery usage that was crazy! the app showed where the usage went from 99ma to 2399ma drain and I lost 8% of the battery in that one minuet! Keep in mind that the battery is only rated at 1500mAh to begin with. With that being said, I was thinking I have a short in the phone! The spike happened again later on that brought my phone to it's knees!
while reading further into the thread, I installed watch dog lite. Immediately after the installation finished, I started getting flagged for an app using over 60% of the cpu while the screen was off! Fancy widget 1.3, I had liked this app so much on my old Moto cliq, I imported it over to my defy.
Maybe I have found the culprit, I donno. This is just my experience so far, if anyone can add to this, please do. I will continue to monitor the phone and the activity of the apps. I am still shocked about the battery drain spikes that I saw! I am still, to my knolage, running the stock rom that came with the defy, now with the addition of Clockwork MOD recovery installed.
i have issues too, in the last week my battery dies in 13-14 hours with normal use. before that, it lasted 24-25 hours with heavy use. i also have sudden pattery percentage drops (which is probably the same as yours, that 8% in one minute). i already tried reflashing sbf/cm7, calibrated battery with cwm and app, nothing seems to work. now i disabled boot oc and use setvsel, and installed battery monitor widget and watchdog lite, maybe those will help :S

Since I installed rc1.5 my battery last for a fairly long time. It droped from 100% to 26% in 23 hours with medium use (data connection always active, when I used it heavily I turned on 3g, I used wifi and I was on a sunny place so the screen was bright)
Sent from my MB525 using xda premium
many have reported battery drain on rc1.5, seems its not present in every case. just installed 110909 nightly, so cant really report on that yet, but ill do as soon as i can.
Im on CM& RC 1.5, my battery last me a long time (more than 30 hours) using a lot of wifi + edge data, and lots of calls and sms, so i guess i dont have the battery drain bug
Hello all together
I'm browsing xda for a little more than a year now. You guys helped me a lot!
First I want to apology my english, I hope you understand what I want to say
Not a long time ago the battery of my WFS lasted up to 3 days (incredible if I think of it now).
That was with a self rooted stock rom and some changes (bravia, turboboost script, oc-kernel, etc.).
Out of nowhere I had problems with my calendar.sync.provider. Processes htc.bg and htc.bgp used the most of my battery (found out with Battery Mix).
I could watch the percent falling... Battery was getting very hot.
After i killed calendar.provider and calendar itself those bg-processes disappeared and all went back to normal.
Installed m1nd's rom, tried a lot of different settings, used calengoo instead of normal calendar (uninstalled the other)...
But battery life was never the same since then.
We also had a really rough winter and I was outside a lot. my battery began to drain faster. First I began to install apps like "auto wifi toggle" to stop that battery drain, after all I just bought a new battery this spring - 1500mAh.
But other than i expected - battery life did not increase. So I decided to install CM7.2 (wanted to do it anyway - great work btw!).
And guess what, nothing changed...
You will find some screenshots at the end... (did barely use the phone this 4 hours)
So what can I do? I'm desperate. The battery does not hold the whole day...
Please give me some tipps (if you have others than the general battery saving thread) or at least cheer me up
tl;dr: Phone works for 10h (mail,text, no phones, no games) - Changing battery & ROM does not fix battery drain...
Thank you in advance!
it happens to me too unfortunately, i charge it everyday or every 2 days
when i play a small mini game for a few minutes, battery drains like over 10% in a few minutes.

Thing is, I charge my phone everyday. And I've been using CM7 or CM9, battery life never lasts more than a day. If it's only lasting 4-10 hours. Check your sync settings. Keep it only on 2G networks if using data. Get a battery saving application, in my opinion, it sounds like your using a lot of mobile data/wifi.
I switched to jellybean (android 4.1) recently. The system is great. However it drains the battery much more than cm7. During a night the battery can reduce from 80 to 60. Is it normal? If not is there solution to extend battery usage?
Unfortunately, that is normal. Turning the fire off can save the battery, but I just charge it everyday. Compared to rooted stock, battery usage increases between 10 and 20 percent for me under normal use.

According to Better battery stats, most of the drain on my Kindle is caused by AudioOut2 wakelock. I failed to resolve the issue and i'm not sure what is causing it. I would like to know if anyone else experienced similar issues.
IMHO, it must be sort of a bug since JB is fairly new and devs need time to resolve all the issues.

That's not normal for a standby... it should be <5% ...not the mention that device does not have to communicate with 2G/3G networks (unlike smartphones), and on my smartphone i get average of about 3days (medium usage, light on wifi) without recharging
It's a bug - some process prevents device to go to sleep (aka. wakelock) which causes drain. I expected at least 2-3 days on a single battery charge, and tbh, recharging it daily is little bit disappointing Something tells me it's a kernel bug since i encountered it on every CM10 rom so far :S

Well coming from an previous ICS build it's a major improvement. Typically the battery life from ICS builds(That I used, Energyrom, AOKP Kindle Edition, GedeRom) would drain 20-30% nightly like the OP said, so coming from there it seems like JB fixed whatever was killing the battery. I can probably go a week with light usage on my kindle before I recharge it. ICS in general drains the battery on any device. I used to get 5 days on my Droid 1 running CM7. With ICS I'll go through 3, though I never want to go back to Gingerbread, hahahaha.

My record for battery on a smartphone is 6 days... using ICS
Anything that drains battery more than 1% in 1.5/2 hours in standby is bad, no matter what OS version...
I also have the impression that on a fully working Jellybean ROM, battery usage is more intense than on a stock ROM. I still prefer the advantages of the new ROM, and also charge daily. Being mobile, I use the XTPower MP-10000 Powerbank, which gives more than enough battery life and charges the kindle while in use to 100% full. This has resolved the issue of battery drainage for me.
Hi, now that i have your attention!
I have cm7.2 democracy on my gio
I barely use it for wifi or gaming now because the battery is S**t.
I had 2.3.6 GB before and battery could take out 2 days on games and music. Now suddenly after switching to cm7.2 i need to charge it twice a day without using any app or game. just some texting like 10, 12.
I use ondemand governor and max freq is 806 min is 245
Also a couple of times i have seen that when my battery is at 30% and charge it then within 5-10 minutes it showed 100% charged. Unplug the charger.
Any suggestions or something on this? I really need an answer guys. Thanks
I can tell you that you can't charge your battery within 10 minutes.
Charge it at least 2 hours, 2.5.

No one has found a solution 'till now?I'll try to use ODIN and go back to stock version, maybe that will help. Has anyone had those battery problems before using a custom ROM?with stock my battery used to last 2 days with games and music etc, now I can only use it for 5 hours without any games or music or internet. It also charges from 0 to 100% in 30 minutes , maybe less. I'm still hoping someone found a solution for this problem because it is useless to have a phone without any battery.
Try to get a new battery because huge draining problem is not caused by roms it caused by battery damage.my battery runs on stock rom over the 10days without using anything but on cm9/10 roms it drains faster but still runs more than 3days for me.
so no one got it?
Thank God I am not the only one here
But guys, I have been using stock GB for an year. Its been only a week on cm7.2 democracy and nightly.
Both have same battery issues and non of this happened in stock
It's not the battery issue.its something else. I'm sure
Have you tried going back to stock version using ODIN?I think that is the ultimate solution before sending my phone to service(I still have warranty).

Try to "recalibrate" your battery; in cwm theres an option "wipe battery stats". some say its nonsense, some say it really helps; i would give it a try.
No idea if theres an option with stock roms, though.....
I'm calibrating now...Will post the result in a while. (Tomorrow i guess)
I still couldn't solve this..I flashed the stock firmware with ODIN and still no luck, I'm starting to think it is a hardware problem, maybe I will send the phone to service now that I have the stock firmware back. Has anyone found any solution?
Hey, i found this article
For the users who like to try out new ROMs very often or by default Android receives updates to Android very often. These updates re constantly pushed to the users to provide the better experience to the users. For those who flash their mobile handset with custom ROM they are advised to charge their handset to 100 % battery life and then proceed with the upgrade processor. That is advised because if you have 50 % of battery life and proceed with firmware update, the new custom ROM will consider 50 % battery life as the full battery stats and this will provide half the battery life then earlier as specified by your phone manufacturer. In those cases you need to go with the battery calibration to gain 100 % battery backup as specified by your provider. There is complete procedure on how you will calibrate your phone battery is mentioned by us and if you would like to make the process very much easier then you can make use of a specially designed application which calibrates your battery. (Battery Calibration)
Okay so i flashed a new custom rom with 100% battery but no luck on battery issue. Its still draining the same.
then i calibrated my battery with this app with my battery at 100% which of course is 50% as said by this article, the app said "Your battery has been calibrated by 6%". Don't know what that means.
ANY HELP? DEVELOPERS PLEASE GUYS!

I have the same issue, I am using CM10.1 RC0 by Olddroid but I think my problem is the charger. For the last month I charged my Gio using the usb connection from PC. Now, if I use the charger the battery drains faster than charging with the usb connection method. I am gonna buy a 1500 mAh battery and hope to solve this problem.
