I'm currently using MildWild 4.3 Final and find the battery level decreases on idle far too quick. I've checked using badassbattery app and nothing untoward is shown in there. Any advice would be greatly appreciated

firstly, need to know what your actual decrease over a period of time, and whether you have anything syncing. and also what you're expecting or wanting it to be. this can be very subjective. what you're already achieving could be quite good. age of your battery is also important.
- assuming you're using inbuilt kernel, set min cpu to 245 ondemand
- betterbattery stats is another useful app to check partial wakelocks (bad apps keeping phone awake)
- use something like currentwidget to monitor idle battery drain if you want to. with screen off, 3g on, the minimum standby drain you can normally achieve is around 3-5mA drain.
if the above checks out, it's probably not a rom issue, may just need a new battery. switching roms may make a difference, and you can try the above on others to actually measure if there are any, rather than placebo. oxygen is supposed to be of the more efficient variety anyway
I've done all those things and I'm also using a brand new genuine HTC Desire battery. I still find that when I leave my phone alone, no Wireless or data or any app running in the background, the battery goes down by 10% every hour or so.
woah then that's way too much, definitely doesn't look like rom/sofware issue to me, sounds like hardware.
what does idle battery drain report?.
i think there are other apps which will measure the actual battery capacity. if it's official should hopefully be close 90-90% of the stated 1400mAh capacity i believe.
not sure what else to suggest which will actually solve problem this however, other than repair
Use the manu 2.1 axi cfs kernel. Only lose 2% an hour with wi fi set to turn off on screen off!

ManU is not designed for oxygen, also loses camera drivers by doing this. 2% idle drain / hour is not that great either...50 hours standby with screen and wifi off...
@elrasho, you could try flashing a different rom or stock RUU to be absolutely sure. if you've done all the sensible things above like checking bad apps and still getting ~10% drain / hour, you can pretty safely assume it's hardware...

2% an hour is so efficient! You find another ROM/Kernel which can give you the same battery drainage.
Oh and I thought he meant mw cm. For oxygen use thalmus mod 8 using smartass v2 governor

stock/inbuilt kernel with ondemand should work just fine. mod 8 is based on slightly older sources. whether smartassV2 is better depends, but i think it has to be actually measured, not 'seems to last longer'
The older kernels tend to be more power efficient ala manu kernels. I've never tried leaving my phone on standby and waiting for it to discharge. I get 14 hours out of my desire a day with mw cm 4.3 with manu 2.1 cfs kernel under moderate to heavy usage

not tried enough, though i trust bortak!
but no rom should give you 10% / hour idle drain...stock rom/RUU with nothing installed is an easy benchmark to test

What is the best ROM for battery usuage?
Every sense with leedroid kernel...
Sent from my Desire HD using Tapatalk
i use revolution hd 3.1 and its great for performance and battery
I will second that Revolution HD 3.1 makes such a difference to battery life, its much smoother than stock too. Tried CM7 and CoreDroid but they were both a little too battery hungry to be useful.
ROM, Kernel and Radio
I have used LeeDroid HD, Spike CM7 and Android Revolution HD. All with different kernels and radios.
I would think the battery drain has to do with both ROM, Kernel and Radio versions (and maybe more). So it's vital that all the components is compatible. Most ROM devs recommend both a radio and a kernel.
And of cause it depends on all the services and app installed after the flash
Anyway, to you question:
I use the new Spike CM7 build 19 and have great battery life now.
I had problems with no sleep mode on other ROM/Kernel before. (and yes I have tried various patches)
I'm using CM7 latest nightly with mad murdocks battery fix and the the most latest radio and I'm getting 3-5 mA battery drain while in standby (with constant 3g, mobile data and sync on). So I'd say all the roms are quite close to each other when it comes to battery drain nowadays and the battery drain isn't a main concern anymore while choosing between roms.
My friend and myself bought the phones on same day. He runs Revolution and I run LeeDroid. Looks like there is a small advantage with LeeDroid.
i'm using Spike CM7 build 19 flashed with mad-murdock's batfix build7 and my battery life is great
I recommend Android Revolution HD 3.2 for you!
I had 2-3 days of battery with ARHD3.1 all the time!

I'm not saying that it isn't possible as you can get a week out of the device if you just let it run on standby but as soon as you switch the screen on the consumption jumps to at least around 200mA and add a little gaming, browsing etc the consumption doubles from that (not an exact figure). So what I am saying is that it's kind of false to imply that another rom has way better battery consumption if you really don't use it that much. As it has been implied in many other threads that you just can't get over a day out of the device if you actively use it. It's just maths and there is no way around it as 1230mAhs will only get you that far
It is possible to get a few days by using it as a "regular" phone, it is all really usage dependent, and therefore the times are pretty hard to compare.
I am seeing a battery improvement using Coredroid V4 over Coredroid V3.2.
Today I have given the phone light use, about 4 short phone calls, email browsing, some facebook browsing but no gaming and I am at 73% after 12 hrs from full charge.
Combination of Buzz 1.3.8.2. 1.61GHz kernel, ARHD 3.2 with sense and the recommended radio is working great for me battery- and performance-wize. Using On demand gov at 1.22 GHz with 230-460MHz screen off profile.

I did'nt say that it all depends on the ROM I use, but with my normal mobile phone lifestyle and this ROM I get those battery lifetime. It was ment as an example, because on the other hand, if I use my DHD more frequent with playing games and stuff, I don't get around the 24h with a single battery charge, but that's (like you say) ROM independet because of the big display consumption and the 1230mA battery.
I just wanted to state the ROM I use with my normal battery experience for the thread author to test out.
It all depends on the user

Hi guys!
This One X is very performing smartphone, games are really pretty... But I can stand that battery problem! I've tried so many rom, using setcpu for ondemand governor of the Tegra3... But I still not have so many battery life!
Can you guys suggest how rom, kernel or something else can save my battery?
Generic suggestions about this problem... Now I'm using Jdroid exodized 3.0.3 with bricked kernel v0.2, but battery is so draining... 63 % of battery with 1.37 hours of screen.. 4 h 22 min on it! =(
Hi!
I see a lot of people complaining about battery life, but if you take a look around you'll find the thread where people posted their battery usage. Me - I'm using rooted OneX running the stock ROM and am more than satisfied as far as battery life goes. I do 15 hours with ease. If I try to save it it usually lasts for more than 24 hours. Maybe you could try stock rom + root ... maybe a little underclock? I've been hearing underclock is quite the juice saver.
Hi,
I am the same I have tried custom Rom's but they claim to improve battery life but they just move the tegra 3 powersaving driver into the correct place!
I have a unlocked O2 HTC One X with O2 Rom and flashed battery fix and rooted the device!
Using this thread: http://forum.xda-developers.com/showthread.php?t=1597227
I have managed to setup a shortcut using widgets on the screen to select how many cores I want to use. I find that using one core clocked at 1.5GHz is fast enough and I don't have much lag! This has helped my battery massively! This is because O2 still haven't pushed through the HTC updates yet!
And also using this thread: http://forum.xda-developers.com/showthread.php?t=1630200
I flashed this using CMW and this has also helped.
I also find disabling some stock apps using App Managment in Settings, also using CPU spy from the Play Store and Battery Usage in settings. I can find the apps that use the most CPU power then uninstall or limit their usage (maybe using the internet instead of a dedicated app) this then has the phone stay in Deep Sleep for longer. I can easily get through 24hrs without having to try to save battery at all! I sometimes have almost got two days without charging!
Another tip is in the Usage app you can Restrict Background data over the network although when you connect to your WiFi it enables it again. Although it is meant to help save your Data it can also help your Battery Life.
Hope this helps!
Steven
Thanks for the answer!
I noticed that, in this Rom that I'm trying, I've the Screen that consume a lot of battery, even in the lowest brightness mode. Not using WiFi, 3g data, autosync, nothing, only a lot of text message received and sent. I think that this S-LCD2 consume a lot of battery or maybe the software of HTC, this time, is a loot poor of balance with this expensive hardware.
Do you think I can improve battery life with the tips that you said? I'm using this ROM right now http://forum.xda-developers.com/showthread.php?t=1597778.
Setting CPU to ondemand governor 304 mhz min and 1.5 ghz doesn't help me? I must disable some cores? I can give it a try, hope that this tips can be made in this AOSP Senseless Rom.

I'm asking myself [ and you ] if this screen consume really a lot amount of battery... Or there is some problem with my one x... Reaching the 3+ hours screen on is a good result, but in a 15 h battery day life, I hope... Maybe I can reach disabling a couple of processors
Don't worry about the screen, it will always take a lot of power whatever you do! It isn't worth messing with it.
You don't need to mess with the CPU although personally it does make a diffrence to the battery, I don't notice it too unless I am gaming!
Maybe an app is preventing your phone from going to deep sleep whilst the screen is off
Try using this app: https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&hl=en
If it says that your phone hasn't been in deep sleep, We need to try and find the culprit. Once you have done this maybe post back and I might be able to help you sort this out! It took me a while as I had this problem but it was definatly worth the effort!
Try looking in battery in the settings and see if there are any apps that are using a lot of power (maybe take a screen shot) and also try in Data Usage, there maybe apps using the Internet whilst you aren't using the phone. This also wastes the battery. If you restrict background usage (only on certain apps) it will only use the Internet in the background whilst you are connected to wifi only. Facebook is a good example!
Hope this helps

If you don't understand anything please say, I know my explanations are awful but I will try my best! I think I have changed everything here to fit your rom!
The rom itself although you or the developer know this but the overall system could be causing a problem! (just a theory!)

You're too fine with me steven, thanks!
I've downloaded Cpu Spy and it says that my one x has been in deep sleep for 70 % of time, so there is no problem with some apps doing something during screen off. My problem is that when I'm using all 4 cores, without internet via wifi or 3g, without autosync, nothing at all, and screen at lowest brightness, there is still a drastic battery drain while I'm using only Message app a lot. I don't wanna think that my HOX have a fault battery, but how can I test and prove it ? I don't know if there is a program, app or test for doing this thing.
Now I'm with that ROM Senseless AOSP ICS, I will try next charge with two cores actives only and view how much I can stay with that SetCpu settings. I'm using this settings: 101% Battery <, CPU Max 1Ghz to 51Mhz and priority 100, governor ondemand ; screen off, CPU Max 1Ghz to 200 mhz and priority 100, governor ondemand. I'll give you the result soon.
you need to give it time to settle the battery mate. i manage to go a day or two and have like 3 hours screen on time and that is with everything on. if you need any help send me a PM mate and i see what i can do to help you. and i would not use SetCpu for now i am using No-Frills. And switch from ondemand to Interactive. and that is with 1.5Ghz as max and 100mhz mininum

I agree that you should not use set CPU although you are best using ondemand as that is only using the amount of power you need, interactive keeps the speed high to increase the overall speed. (not good for battery life) also maybe, my mothers Samsung Galaxy S2 had battery problems and she got 6hrs of battery out of her phone at max, she always carried her charger around.
I calibrated the battery without using any software, I just fully charged the device and left video/audio/maps on to get rid of the battery as fast as I could and then fully charged the device. All I am trying to say is give this a shot (I did this when I first got my phone) she now gets on average 2days battery life! I know that it can take ages but it is defiantly worth the effort!
Hope this helps

Hello,
I have a high battery drain because of "Android System". I lose about 3-5% per hour of my battery in idle state. I turn screen off and didn't use it.
I'm using Slim ICS ROM with franco kernel #174.
Badass Battery shows me that following included processes are in Android-System:
Code:
com.android.systemui
system
android:ui
com.tmobile.themechooser
surfaceflinger
com.android.settings
servicemanager
So anybody know what's the problem here?
I'm already disabled Google Photo Sync, NFC and GPS because I didn't need that. Also googling for the problem doesn't help.
Hope you can help, thanks!

Again, I've mentioned this twice today: Bullsh**, I don't mean to be disshonouring, or anything, but please, give proper answers,. It's all good, that you want to help, but only with proper and correct answers.
Right, back to topic;
Go into your dev. settings, and uncheck everything that doesn't need to be checked (Stay Awake, Strict mode, etc.) Undervolt the CPU, that should save a ton of battery charge, and underclock to 900-920 MHz, that is definitly enough, on a dual-core
Thanks for your answer =)
I think my phone is already undervolted through Smartreflex in francos app and I also tried underclocking by setting max cpu to 1036 Mhz (instead of 1200 Mhz).
The problem disappeared after 1-2 charges (don't ask me why..).
And now after flashing Slim ICS 3.9, battery time seems to be ok (for me at least).
Per hour in idle state the phone consumes ca. 2-3%.
I ask myself how do others get 1% drain over night. Is that even possible? Tried very much kernels (franco, trinity, glados and leankernel) and didn't even get near that.
Any tips?
OP Im glad you mentioned the issues went away after a few charges. this has been an issue for some who do not believe that a few charge cycles does anything. well im with you as i always see things sort of "settle down" after a few days of flashing a new rom.
I have the same problem on my Nexus S.
The process consuming battery is surfaceflinger. I can see it on battery screen before the name change to Android System.

Yes, it is possible. I get 1 or 2% drain overnight with wifi and mobile data disabled, and up to 5 to 6% if mobile data is enabled overnight.
My record with it is 1 day and 20 hours from 100% to 3%.
I had a LG Optimus Black before and didn't last a day. I'm loving this Galaxy Nexus.

I would like to achieve battery drain like that, seems like what it should be.
I am running AOKP Build 2 and I feel like my battery life is ok but not great. I let my phone sit overnight last night with sync off, but LTE on and it drained roughly 4% an hour. I actually turned off LTE in the middle of the night to see if there would be a difference, and no, it drained at the same speed on 3G as well. I live in an area with pretty good reception actually, GSam says I spend the vast majority of my time with a signal strength of 4/5.
GSam reported that roughly 34% of my battery drain overnight was due to Phone Radio. Another 52% was due to app usage. Drilling into that it tells me that over 40% of the battery drain from apps came from "Android System", "Phone" and "Kernel". Under Android System, which was by far the greatest drain of the apps, it only kept the phone awake 1m18s overnight so that doesn't seem excessive. However, I'm confused as to why, with a good signal/connection my battery would drain at nearly 4% an hour whether connected to LTE or CDMA. Unless the radios in this device are poor, I have a hard time believing there isn't a way to fix this without using something like Juice Defender.
I can't recall because it's been so long, but I don't really remember any ICS ROMs draining this fast. I'm on a clean install of AOKP B2 and I've tried a few different kernels with the same results. Any ideas anyone?
So I wanted to let you all know that after trying a few different ROM/Kernel combinations all with similar idle battery drain, I installed the latest (9/21) CM10 nightly and I only lost about 10-12% overnight last night connected to LTE. That is a much better drain than the 30% or so I was seeing previously. Not sure why but my phone just hasn't been handling the latest AOKP builds very well. I am afraid to try a different kernel right now as I'm leaving town tomorrow for most of the week so I'll leave it as is until I get home next weekend, and see if I get this good of battery life with the latest Leankernel.
Surfaceflinger
The same happens to me, this app appear in BetterBattery stats, Surfaceflinger appear as the culprit of my 45%+ battery consumption caused by Android Sys
When I first rooted my phone (xperia S) I noticed an 31%+ energy consumption by Android Sys, I reflashed and re-rooted and stoped for 2 weeks or so, now 2 days ago I woke up to find that 81% of the battery is being drained by Android Sys, then it lowered to 31-43%. I noticed that when I refreshed the stock "Battery" app ,"Surfaceflinger appear for a moment, I seem that I confirmed with the BetterBatteryStats, Surfacaflinger appears at the top.
Why is this happening? Can something be done about it?
PS: I cannot change kernel, bootloader is locked...
Surfaceflinger and android.process.acore are top battery drainer. I mean how to make them not sucking on battery?
I flashed Jellybean for my gnex this last weekend, and I've noticed a severely precipitous drop in battery life (15% in 90 min, 15 min screen on). I found this yesterday when my phone went completely dead after just 6 hours on idle, despite running some pretty severe power-saving options. I can literally see the battery draining as I took the screenshots to post.
Running 4.1.1 stock, Franco Kernel Version 5 (power save powermode), 2100 mAh battery - I tried to provide as much information as I can in the screenshots. The weird thing is that none of the information stands out as an obvious power-drain, its just falling for what I believe to be no good reason.
Please help!
First of all: congrats if providing such detailed information about your battery information! (I'm being serious, not sarcastic)
Secondly, have you tried running it with WiFi only to see if there's a difference? Also, you need to go through about 2-3 charge cycles before you have a good idea of our battery range.
Also, what kernel are you using?

Kernel
I'm hoping its just running it a few charge cycles fixes the problem, because my battery meter is like a countdown clock right now.
I'm running 3.0.41-franco.Kernel-Milestone5.

I reccommend getting cpu sleeper. Its brillant and saves me tons of battery
https://play.google.com/store/apps/details?id=com.eugene373.cpu.sleep&feature=nav_result#?t=W251bGwsMSwxLDMsImNvbS5ldWdlbmUzNzMuY3B1LnNsZWVwIl0.
CPU Sleep
Thanks! However, I'm already running on only one core, from a setting in Franco's app.
My problem is that there doesn't seem to be anything glaring that is draining my battery. Awake time is slightly more than I'd like, but not nearly enough to drain the battery at 10% an hour with the screen off.
And for the above poster, I have not tried running it with wifi only and no mobile data - wifi at my office is spotty, and I'd like the conditions I am testing it at to try to mirror how I would normally use my phone.

hmmm... did u try replacing the battery?
Battery
No - the battery worked just fine on ICS as of last Friday (28 hours standby charge). I would hope that flashing ROMs/Kernels would not actually damage it.
Thanks for trying to help - I'm really confused since all the ratios look comparable to people who get great battery life, but for some reason, just seem to suck about 5x more battery for me, so its impossible to pinpoint one specific culprit. I thought it was a mis-calibration, but apparently that is just a myth.

Let me start by saying that I am not an expert, but the following tips helped me. I agree with the WiFi and the detail you provided was great. I see that you are running 4G, this will eat up the battery. Your ROM may have a toggle for the 4G (LTE) and 3G (CDMA). If you have WiFi available I would use that. You may want to turn off the NFC (system setting>Wireless & Networks More....) unless you use google wallet or share screen alot. Also, I had horrible results with the Facebook app running in the background, which I have taken off my phone. I set a bookmark in dolphin browser instead of using the app.
If you are not seeing any improvements with in the next few battery cycles you may try wiping the battery stats in Recovery. The first ROM I flashed from stock my battery life was all over the map and wiping battery stats helped. I ran the same Franco Kernel and was getting 2.5 -3 hrs of screen time. Hope this helps.
also, get CpuSpy from the market, and see which speeds your cpu is using (or not using).
Not that this will help software issues but Sprint is giving away a free 2100Mah extended battery with the door. You just have to pay for the shipping. No scam at all, I think they know that they have a glitchy piece of product and need to help calm us down. Just call telesales and tell them you own a Gnex.
CPU Speeds
Almost exclusively at 384 or 729 mHz, capped at 1026.

So that means that the CPU isn't going into deep sleep, which is an issue.
All I can suggest is reflash with a full wipe, and reinstall the apps you can, and slowly weed out any rogue apps that could be causing said issue.

Deep Sleep
Sorry, I meant that when awake, the vast majority of the clock speeds are 384 and 729. I am in deep sleep approximately 75% of the time.
If no solution comes up in this thread, I will try re-flashing to stock JB/stock JB kernel tomorrow night to see if it just needed a few recharge cycles to stabilize, and if not, if wiping/reinstalling helps.

I'm getting the complete opposite of u op
Sent from my Galaxy Nexus using xda premium
Yeah, that seems to be the general experience here. My phone is down to ~28% since the OP. Again, the proportions in which things are draining power are correct, they are just doing it too quickly (1% per minute of screen time).
I'm going to completely wipe and re-flash JB tonight, keeping the stock kernel this time, unless someone can help me out.

Did u flash francos kernel yet ?
Sent from my Galaxy Nexus using xda premium
Yes - every process/screen is drawing the typical percentage of power use (~50% screen, 8% Phone Idle, 8% cell standby), but the battery is draining 4x faster than it should. Francos app shows me running at completely standard voltage, and I'm on the powersave mode. I think it must be a battery indicator/stats issue, otherwise the proportions would be all off.

Hi guys,
I recently switched to CM 10 (Android 4.1.2) and the battery life is significantly lower than what I had on the stock ROM and the new Sense UI... I guess.
My phone won't run longer than 10-15 hours a day with normal usage, which means Wi-fi and 3G always on, screen on automatic brightness being used for about 1 hour in total (for one charge). However Android OS, Cell Standby and Phone Idle still account for the most battery usage, which I find weird. I have no wakelocks and my device goes to deep sleep when not used.
Is this normal behavior with the new Cyanogenmod and Jellybean or are my expectations too high? I already read most threads concerning battery life, but most of them discuss problems such as wakelocks or similar issues. My question relates to the normal behavior of CM 10.
I am grateful for all replies on the matter or personal experiences.
It's known that CM10 battery life is worse than stock JB. You can try different kernels and different governors, but it's a trade-off between life and performance.

I don't understand, I thought that CM is stripped out of unnecessary background processes and apps. As long as I'm not using any CPU or GPU intensive apps like games it should consume less battery than the stock ROM. Is there something I'm missing?
Maybe the updated kernel and drivers give better power effeciency. When the JB kernel source is released, hopefully CM10 and other AOSP ROMs will also improve.
You were saying about on screen time?

CM 10 really uses a lot of battery but of you could switch off wifi and 3g when not using, and clearing all the apps frequently in the recent menu may help... My battery then lasts from about the start of the day till night though the batterys now quite old.

i got a weird battery life yesterday, i was walking from work to home, i started watching videos on youtube, looked at the battery, 31%, after few videos looked again, still 31%, i walked 41 mins with a total of 9% of battery drain, i also played a game for about 25 mins, it was a really battery life.

That's pretty much my battery life as well. Regarding age, I'm really concerned, as I'm not able to open the phone and just replace it. But I guess that much better smartphones will come along before I consider getting a new battery and it won't be worth it any more.

I get that sometimes as well. I pick up the phone a couple of times and the battery is always at, say, 50%. Then, a couple of hours later I read a message and it suddenly jumps to 41 or lower. But from what I've read that's normal and no cause of concern.

I heard what causes the CM10 to have such an awful battery life is something that was supposed to save power when you lock your phone [Which is normally quiet often] and actually causes it to depelt, so it obvoiusly doesn't affect screen time
CM10 is a horrible ROM, get something else... I used LiquidSmooth for a while, it's a great ROM
Now running ParanoidAndroid 2.53
Btw, Stock ROM had a wonderful battery life, I only realize that now ... lots of ROMs can't reach that much

That's exactly what I did, flashed the old RUU and installed all updates. I don't know how the guys from HTC managed to do it, but the battery life on Android 4.1.1 and Sense 4+ is AMAZING. I easily get 24 hours with normal usage, over 2 days if I'm really careful.
This is what I got during a night sleep with cm 10.
I installed it yesterday so its kinda new tot me. What causes this?
Sent from my HTC One X using xda app-developers app
Probably some nasty wakelocks. Install with wipe/factory reset if you didn't so already. Then try betterbatterystats (search xda) to find out what is causing wakelocks.
