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.

http://forum.xda-developers.com/showthread.php?t=933951 just uncheck bluethoot when you don't use it.
I get from 1 to 2 days with moderate use.
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.

I feel like I make a thread for each phone I go through. First Blackberries, then Droid X, now Galaxy Nexus.
I am getting pretty horrible battery drain that is definitely worse than others' Nexuses. I have gone to the extended battery now for a few days, yet in the morning, when I unplug from charger (says 98% but charged?), with brightness only a quarter of the way up from lowest, I can literally watch the percentage (battery number mod in corner) drop one-by-one each minute or a few...So if I am actually using the phone, you can imagine it drops pretty fast. Yesterday, with very very moderate use the phone was still dead within 5-6 hours. It was at the mid-80s within an hour or more. Again, with moderate use.
It is stomach-dropping watching the percentage number just go down and down. Yet my friend's Gnex using the extended battery his first day did not hit 85% yesterday until 5+ hours later. The battery stats page on mine shows nothing with high numbers except Screen and Android OS, so I assume no apps are draining it. I am rooted with unlocked BL, on bigxie's deodexed ROM with softkeys mod, battery percentage mod, and power menu mod. I have 100-something apps and many widgets but no battery draining/updating ones. Others with the same ROM report fine battery.
I believe after using the ext. battery for a couple days, it should be "conditioned" if needed at all, yet I see no improvement.
I'm getting very angry watching this drop.. For example, 40 minutes off the charger with almost NO use except for turning the screen on here and there, I am at 94% battery with Screen at 46%, Android OS at 34%, Phone Idle 11%, Cell Standby 9%, and Android System 2%.
And then 1 hr 20 min in, at 88% battery with 55% Screen, 27% Android OS, 6% Phone Idle, 6% Cell Standby.
This doesn't sound normal right? Keep in mind, those numbers are with almost no phone use..very minimal settings menus visited and one update from Market.
Jesus, literally almost every time or two I turn the screen on just to check these numbers, I see the damn battery percentage drop a number. Not even using the phone how/as much as I normally would be. This is infuriating. Luckily, it doesn't seem to drain much with the screen off.
Quit checking and wait til the bug is fixed and blood pressure stabilizes?
Crazy world, ay?
Update to 4.0.2 or 4.0.3 with an improved kernel = success.
Use the phone for 1-2 weeks to stablize battery life - mine is better now than it was when I began using it. But the kernel/rom makes a big difference.
Thanks. Any suggestions on with combo to use now? 4.0.3 preferrably I guess.
Then why does my friend on totally stock 4.0.2, non-rooted have that great battery life from the first day using the extended battery?? I'm pretty much basing mine off of his and other's who are getting ridiculously long life. I never understood how it varies SO much. We should all have the same relative to usage.

No. Because no two phones are set up the same. Too many variables to say relatively same usage. For instance, when i go to bed i get 2-3 hours standby per percentage point. Not everybody is going to get that.

Maybe, but the fact that I have no other visible outstanding draining factors, and I get no 4G at home and therefore have it set to CDMA only...I should not be seeing 1% drops almost every time I turn the screen on for more than 30 seconds. Especially with an extended battery.
God forbid I want to use GPS or 4G.

Wow, really? At first glance in all sub-forums I saw about two, if that. I have a legitimate concern, especially when my friend is getting about 4 times better life. Thanks for your help though in the device forum where this 'doesn't belong'.
..And over the course of only a few minutes of the screen being on maybe twice and sending one email, I saw it go from low 82-83 down to 77. ****ing awesome.

You probably have a misbehaving app. Download better battery stats from the android apps and games section here at xda and let it run for a day or so and see what processes are being used the most and what your wakelocks are, etc.
Also, find a 4.0.3 rom with a kernel that can be undervolted and try that out.

Thank you, downloading now and will check it out.
I'll admit I'm using the GSM version so my experiences may not apply but for the first few days my battery life was utter crap.
Its been MUCH improved over the last few days, I dont have the wakelock issue and with the screen off the battery drain is literally only about 3% per hour, and thats with background data on.
YES, the screen DOES use a lot of battery, it isnt really avoidable and is somewhat expected with a 720p 4.6 inch super AMOLED screen.
The one thing I can recommend doing is finding a modded kernel and undervolting that CPU - It seems they've been really rather generous providing power to the thing, I've been able to take off at least 100-150mv across the board.

This - My battery on the stock battery on GSM sucked first few days, and I was really concerned I made a poor purchase. But with the screen on probably 5 or 6 hours of my work day it lives through the day and just enough to get home after that. I can charge it at work too, which I usually do. On my day off it survived 18 hours and still had ~20% battery life left on 4.0.3 AOKP/Francisco.Franco Kernel
From my experience, the battery life isn't bad. I did install the "extended" battery as soon as I bought the phone but is isn't much bigger than the stock battery. I am on stock rooted 4.02. With LTE off I use about 2% per hour in standby. With LTE on it is almost double that (3-4%/hour). I have several widgets running and gps enabled. (wifi when available) I can easily get a 16-18 hour day and have 50% remaining when I go to bed unles I sit around gaming for a couple hours.
I may try a new ROM tonight but I expect it will probably make things worse.
Im running a bone stock setup and im getting 12 -14 hours a day... normally I read posts like the one skiddingus posted and wonder why I never can achieve those readings so i feel your confusion . I do have 4g on and gps off screen is about 1/4 of the way up brightness wise
Hey all,
I recently put Blu Kuban on my phone and I'm loving the look and feel, but I'm having REALLY bad battery life. I couldn't get through the day with only a little use. I download the battery calibration app and tried that. Its also been about 4 days since I flashed the new ROM. Anymore suggestions? I bought an extended battery at 3800 mAh and I'm getting less than a day with the new ROM. Before the update I was getting at least a day and a half with MUCH more usage.
So long story short, BAD battery life. Any suggestions? If I cant get this figured out, I'm going to have to go back to stock.
Thanks in advance.

Hi. I've noticed you posted two separate threads relating to RUJELUS' Blu Kuban ROM. I would suggest you ask in his thread if you haven't already due to the fact that he may offer more assistance.
However, there are many different battery solutions. The problem is, if you were previously running Stock Gingerbread, you must get used to the fact that until Kernel source drops, battery life will not be as good on ICS as it is on GB.
To address your ICS battery problems, I suggest you turn here:
http://forum.xda-developers.com/showthread.php?t=1668853
Also, if possible, it would be nice to see your battery stats. Take screenshots and post them up here.
I would definitely post in the thread if xda would let me. I tried because I had that thought originally and because I don't have 10 posts yet it wouldn't let me post in the thread. I will post battery pictures tomorrow but its pretty much saying like 36% android OS, 20% display at one hour of use.
Thanks for the help so far guys. I checked out the first link and changed a few things. Hopefully it helps.
Still rocking Gingerbread ;p
How old is your battery?
How old is your phone?
How much do you have running in the background?
Do you keep WiFi on at all times (so that it might be searching for signals constantly)?
Use the apps listed above to try and get an idea of what could be causing the drain.
Hopefully it will improve so you can fully enjoy the ROM.

My phone was purchased in October. My battery is about 2 weeks old. I don't believe i have anything but gmail sync in the background. However, I'm not used to all apps I used staying open after I use them so I've been kinda bad about closing them. Is there something I can change so this goes back to closing most things after I press the back button. I do not keep WiFi on.
My extended battery got about 18 hours and was at 15%. I slept for 11 hours last night with nothing on. I used facebook for 15 minutes, just responding to a post and scrolling through messages and battery dropped at least 10% if not more. Granted, I was trying to download the update but doing that for 10 minutes dropped my battery over 20%. I'm very concerned.

I essentially didn't use my phone for half the day. I can't expect with a battery double the size to get 12 hours of light use?
are you on the latest build? Im on 1.0.4.1 and my battery is pretty solid, Id say give it a few days. are trying different modems?
I experienced the exact same thing on that rom. It is definitely one of my favorite roms but I would get half the life that I would on the others I tried.
Were you having issues with battery at all before you flashed the Blu Kuban?
I'm running Blazer ICS now and getting almost as good of battery life as I had on Gingerbread.
So here is my screenshot. In next post ill type how long each process was running.

So 3 hours and 46 minutes. Less than 50%.
Android OS CPU total: 20m 36s.
Stay Awake: 1 hr 8m 34s
Screen: 34 minutes 17 seconds (last 10 minutes or so has been trying to get this post up)
Facebook: CPU Total: 10m 25s

GPS: 3 seconds (turned off immediately after realizing it did that)
Android System: 7m 10 s. CPU foreground: 8 seconds. Stay Awake: 4m 27s
Cell Standby: Time without signal 4%
I figure thats enough but if not let me know. I just updated to the new version so I guess I'll have to give it another few days, however this was typical of the last version. Please help, I really like Blu Kuban.

1. You're addicted to Facebook lol
2. Your signal seems very low...could be your phone is running up its battery trying to get signal
3. What are your wifi settings? Use one band only and leave sleep mode "always"
4. What is the brightness on your screen? Set it lower and unselect auto adjust
5. Sync can kill your battery, either remove some things from sync (like Facebook) or remove them all and only sync manually

Wow, that is incredible!
You slept 11 hours? I have not gotten that much sleep in years!
In all seriousness, I have recently gone back to Blu Kuban and the battery life will get better after at least two full charge cycles. I am currently at 9 hours and 75% remaining. I am in a low signal area and keep data off and use wifif when available. I do use Juice Defender to automatically turn wifi off when the screen is off, so when I am not using my phone, I can still receive calls and SMS.
My battery life on Blu Kuban is really good... been getting like 25-30 hours for the past couple of days. One thing that you can do to maximize battery life is turn off haptic feedback and also turn off pulse notifications. Pulse keeps your phone from entering Deep Sleep and haptic feedback also uses a lot of unnecessary battery.
I found out what my problem was. My extended battery has gone to ****. I took my extended battery out yesterday and put in my standard battery and it is running better than the extended battery. What is crazy is that I replaced my stock battery because it was running poorly and not getting good life. Therefore my 3600mAh battery is running worse than a BAD 1800mAh battery.
Tips though to improve battery life that I found:
Download CPU Spy
Download GSam Battery Monitor (Previously known as Badass Battery Monitor)
- Use this to see what is using your battery up.
Turn off any data syncing you don't need
Turn down screen brightness to an acceptable level
Make sure you close the facebook app because its a crazy battery drain
Give your battery a few days on a new rom to even out
This is what I can think of right now.
Good Luck all!
I see countless comments with people complaining about battery life not being good enough in most threads, and it being affected positively/negatively by updates.
I'm aware a lot of ROMs can have a very positive effect on battery life but I am more interested in the general overview – your battery life's life if you will! The reason I ask for your experiences is that I would like to qualitatively collect a bit of information from a fair few people and see what's to be seen.
It's worth noting that my latest HOX's battery life is exceptional and I believe it's down to a simple life/career change. It's really nothing new to someone who knows their fair share about batteries however I would be interested to compare.
So, list the times you wake up, take your phone off charge, put your phone back on charge, and go to sleep. If you can it would also be nice to know what your battery percentage is at certain points. It would also be interesting to know what hours you do on an average working week and in what sort of work environment (home/architect, office/marketing, shop/clothes retail etc).
If anyone can remember the things off the top of your head, even rough estimates just chuck then in the thread. I will then compare them all to my own personal habits.
Sent from my faster than SGS3 HOX.
Personally for me ICS was 4.0.4 was perfect, after update to JB it's really bad. On ICS i was loosing 1% of my battery during whole night on JB i can even loose 10% ; d. Overall battery drains faster during usage... all stock.
There's already a thread for battery stats.

Fantastic. I'm more interested in people's actual habits not stats about their battery because it only tells one half of the story. Like I mentioned this is more of a qualitative approach, so less battery stats.
I should of assumed that most people would be like more yourself so I will get straight to the point.
I have the benefit of working at home which means I can charge my phone whenever. I'm not forced to charge it over night; having it over charging for excessive amounts of time. I charge mine in the day and as a result I'm conscious when it hits 100% – I then unplug it. Other than natural degradation, I doubt I have ever damaged my battery in any way which has left me with a great battery life.
I was quite interested if most people charge their phones at night, go to sleep, unplug their phones when they wake up etc. This will severely accelerate the degradation of the battery.
well for me, ICS was bad...im using custom rom and various kernel to see which has the best battery life...all bad accept ncx 0.99....well some of the time its ok but some not...the battery percentage in ICS if not using will stay at 1% but for a 5 minute use, it will drop 10%...but amazingly, if you keep using in screen on, wifi or whatever, it will not drop that fast, well for me its ok....but now i have updated to JB still in stock, and the battery life is great.. i have watch HD movie using MX player in 2 hour and only drop 20%....when in ICS about 80%...big difference....i think stock kernel is best...
Well for me it's decent i mean yes it could be better but it's okay... heres my usage: i take it off the charge around 10 am when i wake up or so and it's off the charge till the next day morning with avarage 45-50% battery left and screan on time avarage 2:30 hours - 3 hours, sync with FB , hotmail and weather is On all the time as well is the wi-fi even when i sleep, my reception aint so great tho , around 2-3 bars top 4, 2g network, anyway my tops on the screan time would be around 6 hours with around 30% brightness idk how that guy managed to achive 6hours 20 mins on a single charge on medium brightness , could be jelly bean or maybe partitial charges ( i'm on ics btw ), anyway hox battery aint so bad as ppl may think, besides if you're lucky enough you'll get hox + battery into your hox ( 2100 ma ) which should provide avarage 6 hours + screan on time, tho i bet we could get around 8 with that battery. Hope this helps.
Ive got arhd and i got to say Im happy with my battery life, first I wasnt, when I went through a couple of charge cycles it got better and better. Now I can do 3.5 hours on screen time playing games and use it for atleast 24 hours with a mix of everything with watching videos to on the bus lol. So mines has been really good.
Battery has been pretty bad on any ROM. Now that I have ICJ421, my battery is near perfect. Yesterday I got 14h with 3h22m Screen On time.

I know there are hundreds of these threads but i was unable to find the information that I'm looking for. But my guess is there is no real answer to my question. But i've been wrong before. Please bear with me
Here goes.
I want to know how to maximize the battery when USING the phone. I dont care about wakelocks or sleep time etc.
I am interested in getting to max out the usage time.
For example when I stream radio and surf the net and text. My phone lasts 2 hours with max birghtness. That seems really short.
- I've done all that I know to minimize power consumption with turning off sync, settings, etc.
- I have tasker starting and stopping data during screen on/off.
- I have the phone UV and under clocked.
- I Limit my phone to 3G only, with no LTE
- Also signal is not a problem since I can stream and surf without an issue. With areas with poor reception. I don’t even use the phone really
-*I also have all the chats turned on include facebook, whats app, etc. Once again, phone is awake. and I'm concerned with its ON screen usage battery time.
- I even have the second CPU setting on conservative. (when set on ondemand it drains even faster)
But during usage, its terribly short! What can I do to prolong the life?
The battery was always like this and I dont believe its defective. With regular use, checking phone (once or twice every hour) can easily last a day. But during multitasking usage I notice the drain to be 49-59% per hour according to battery spy.
I know I can uninstall battery spy/BBS to conserve battery. But I'm looking for what some are reporting (4-5 hours of on screen usage time).
Looking for some guru-like advice Thansk in advanced
Personally, I get the best battery life out of the stock kernel of whatever particular ROM I'm running. I stick with tw based ROMs, and I greenify almost everything! I consistently get between 5 and 6 hours of "screen on" time with the stock battery.
You never said what ROM and kernel combo you're using. I know that I get 3 to 4 hours of screen time depending on the apps used and the connections utilized (wifi, signal strength, LTE or H+, etc). 2 hours definitely sounds low though. I'm using stock debloated ROM right now and stock kernel. I have not modified voltage or clocking in any way (yet).

I didnt really notice any improvements on the KT747 vs stock kernel.
I greenify everything except for the messaging apps. But then again, when my screen is on, i want ot be using those apps.

Its in my sig
Stock 4.1.1 JB
KT747
3G good signal.
Using tune in radio while texting on go sms and surfing using chrome with 7 tabs open

You're doing heavy multitasking!! It's going to eat the battery, sorry, but no one's going to post a magic "cure" to increase battery life! Buy an extended battery... Problem solved.

Websurf and radio or text and radio is just 2 tasks occuring.
Well I can say that running on Wifi, I can get regular battery life about 4-5 hours of use and over 20 hours of idle time.
The radio seems to be the main culprit, so the question is..... what can be done about that?
I'm asking because
- I flashed diff modems and seems to yield same results
- other S3 from my friends seems to last longer with multitasking
- signal....strong or weak seems to produce same drain.
Battery?

I've had the same problem. I couldn't get the same battery life as others I know. I always turn my GPS off if I didn't need to use it. Google now seemed to kill my battery so I stopped using it. But, the one thing I did notice is that the battery stats can be a little deceiving. If I left my phone off the charger and didn't use it for 10 hours and then started to play a game, it would look like I was getting good battery life as I would have about 60% battery left. Now if I played the game right after unplugging my phone, and then after the same 10 hours I'd be around 40%. Hopefully that makes sense.
One thing that I did do to overcome this was get an extended battery. It does add a little bulk, but now I can use my phone like I want and not have to worry about my phone dying on me at night. I can even forget to plug it in and still have battery the next day. For me I got the hyperion 4200 battery. The Zero Lemon seemed just to big for my tastes.
The other thing is also the ROM. At times I have found the same ROM but a different version exhibited different results. All ROM's offer something different so it is a give and take situation.
I hope this helped.

Yea my gps only turns on when my map turns on via tasker. I also dont have google now on.
Ya i understand what you mean on the percentages.
Ive seen people wiht great battery life, i wanted to try to acheive that without an extended bat. I was wondering if there was somehting that was obvious, or some radio battery drain fix. (I even tried only 3G, and still drains)
Thanks

It's a little hard to compare, but right now I'm on a 4.3 ROM and the battery life has been exceptional. Otherwise the next one that has been closest for me in terms of battery life has been Dandroid. Also, it's hard to judge a ROM after a day.
I guess I should have asked if you have tried or have any interest in a custom ROM.

I tried customs like AOKP, PA, CM etc before. I dindt notice a gain in bat life.
I do enjoy's stocks stability so I would like to find a solution with my stock phone. But doesnt see like theres one....

I've had a hard time getting really good battery life from the stock ROM. At best using greenify, I could prolong it a bit. If you are interested in a stock ROM with some tweaks, I always suggest S3Rx, or Dandroid if you want a slimmed down version without the bloat.
You can always try the power save mode as that does seem to help some, but you may experience some lag.

Ive frozen most of the bloat, greenified everything, plus I unclocked and under volted it, so any lag I would feel from power safe wont affect me since i believe power save throttles to 1350 ish .
