Now, I do use my phone pretty heavily. My girlfriend and I text back and forth about every 2-5 minutes, all day, which will surely rape some of my battery. In addition to that, I do things like surf the internet, market, Gmail, no music, rarely games.
Is there any kernel, or ROM/kernel combination that has users getting >20 hours on a full charge with heavy usage? I always see people getting it with what they claim as "moderate" usage or they'll post screens and their phone is like 40% idle, 40% standby, which is silly.
Just wondering.
It is...on CM7...with Tiamat kernel...19 hrs at 55% left, 3.3.5, non-sbc. ; moderate usage.
With heavy usage, I had around 18hrs @ 35% left.
I knew CM7 had far superior battery life to Sense ROMs, but only tried SZ with it, not Tiamat. Guess I'll give it a go for a few days and see what happens!
That whole some users experiencing dead SD cards issue kind of worries me, but nothing a new SD card can't fix! Ha.
I see some people sticking with RC2 instead of going up to RC4. I know thgre's a changelog I can check, but is there a particular reason some people are sticking with an earlier release other than that they might not necessarily need the new things added in a later RC? Does RC2 have more stability or something?

Some people are just clinging to it, and don't like change, or they're content with what it offers. Use the CM7 final that was released, along with the Tiamat kernel, you'll be good to go.
Didn't know final was out! (I don't follow CM much.)
Thanks for the tip!
Will certainly flash it tonight!
This was the best I have ever seen my phone do. I didn't use it heavy, just somewhat moderate. Typically with this same combo I will burn through a whole battery in less than 8hrs at work. Of course I am streaming Pandora/Slacker or on PowerAmp alot. But this screenshot was on Myn's Warm Z Nightly with kernel netarchy-toastmod-4.3.2-cfs-nohavs-nosbc-suv-universal-signed. Set Cpu running 1036max/38400min OnDemand and a screen off profile of 652max/245min. The only things autosyncing are Google acct, HTC sense and everything else is manual on my phone.
Of course being in a strong signal/service area is key. At work my signal is weak at best and we have no wifi . This particular stretch of time I was at home for a bit (ok signal) and my in laws (strong signal) working on their car for 5-6hrs. I Then of course let it sit unplugged all night. But I did a lil web browsing, searching, games and otherwise calls and texts. I was pleasantly surprised. If I was in a good service area at all times I'm sure I could run my phone 10-12hrs on heavy use.

I don't see the point in spending some money on an extended when I'm just gonna go get the EVO 3D when it releases. I'll just spend my time trying to find the best combination for me.
try calibrating.
full charge...after light turns green check with battery monitor widget
then clear battery stats, unplug
use the **** out of it till it hits the redzone
plug back in full charge again *checking charge*
see how it lasts...
Ih they're using the same battery and there bit expensive anyway...

Enough said!
I would highly recommend setcpu. I do the same thing as you, mainly use my phone for a lot of texting, and maybe 20 mins of internet a day. I have my setcpu set to 384mhz when the screen is off. This alone saves a TON of battery during the day, and doesnt affect any apps or anything else. I also have step down profiles, so if the battery gets under 60%, it throttles down to around 700mhz, at 40% it throttles down to 500 mhz, etc.
I am currently on cm7, and I can easily go a day and a half without a charge. But when I was on Myn's rom, I could go almost 3 full days.

Are we sure the battery is the same size? Another forum said the pics showed a square shaped battery. I know it's supposed to be more mah than current evo battery. But maybe they are confirmed to be the same size and I just missed that info.

Why not use something like gvnotifier to send/receive texts using your google voice number. The program runs in the task tray area of windows and integrates very nicely with google voice.
http://www.daveamenta.com/products/gvnotifier/
The only issue is texts you send will not be stored on your phone. Both however are available via the website at google.com/voice .
Most of my texts conversations are relatively unimportant, so saving is not vital.
Funnily enough, just the next charge, I got 23 hours on Warm 2.2. Moderate usage, though, not heavy usage.

GVoice has always had such a terrible wakelock for me. Like, the wakelock was the amount of time since it had started the process!!!
I use an SBC kernel, but I didn't for awhile. Here's what I did:
1. Turn off mobile data when you're not using it. Background data takes up a lot of battery.
2. Turn down the screen brightness.
3. Keep screen off as much as possible. My best, with SBC, battery test is nearly two days and my screen-on time is only like 7 hours. Use it for what you need it for then turn the screen off. Display is one of the biggest battery users.
4. Don't use haptic feedback or vibrate. It takes more battery than making noise. Since you're a heavy texter, like myself, this won't seem like it's helping, but it is.
5. Get a kernel that undervolts. That user up there who said use SetCPU to underclock when your phone display is off is basically doing what kernels that has undervolt does manually. Undervolting does it automatically.
6. In my personal experience: CFS > BFS. I'm not sure why, I'm not a kernel specialist, but I use what works best for my phone (0004 Hardware).
If I were to give you a suggestion, it'd be Netarchy 4.3.4 CFS-Mor-Havs-NoSBC. It's in beta but I've been using the SBC version for a month now and it seems to be the best bet for Sense users. I don't know AOSP at all, so I'm unhelpful if you use that.

Which Rom do u guys think has the best battery life?
My say is SILLIAN Rom but it was banned from the site.
So now I am using Virtuous.
Sent from my HTC Vision using XDA App
I am looking for a rom with good battery life, I just got the phone and I love it, but it should have a bigger battery! My Cliq XT had a biiger battery, at 1390 mA lol. I have tried CM7-RC1 and now I'm on CM7 Nightly (released on the 25th). Currently downloading Virtuous and will give that a shot.
Stock ROM. Period.
I have been unsuccessful in finding a ROM that can match the crazy battery life that I got on stock.
I used to get 30+ hours on stock. Now, I can't get more than 10 for sure..
I keep jumping from ROM to ROM, maybe that could be an issue too with battery stats in CWM and stuff... but as far as I'm concerned, stock is the best option for the best battery life.
Sent from my Liquid Metal using XDA App
I noticed No difference with stock over any cm rom i have used. Battery sucks. Htc overall sucks with battery life. For some reason any htc device i ever had sucks balls. My mt4g was probably the only good phone in terms of battery.
Otherwise htc is retarded.... 1200mah is plain dumb on a smartphone.
From my permarooted 1209mhz G2 with CM7 nightly 6
Different people have different results. You're gonna see someone with every rom in the dev section claiming ridiculous battery life. When it comes down to it you have to realize everyone uses their phone different and the rom isn't gonna make the biggest difference, its how u configure and use it.
No matter the rom, using things like SetCPU, juicedefender, etc. and other battery savers can improve ur battery life. Most dev roms are going to offer better performance and life, just choose one you like and set it up the way u like it. The only way to know what to rom offers the best life for u is trying several and comparing.

No. I'm not kidding. Rooted via the non-ADB method. Flashed CM6.1.1 and didn't mess about with any different kernels or radios.
However, when I try CM7, my battery life is halved. Maybe I got lucky. Best battery life I've ever had on a smartphone. Not even my old Dash lasted this well.

Its because hes hardly using his phone... If you have a screen off profile and let your phone sit for long extents of time you can easily get that kinda life. Don't expect it when you actually use it regularly or keep the screen on for any length of time. See these are the people I'm talking about. You're always gonna find someone running every ROM out there that say he/she gets great battery life on it.
I personally am on CM7 overclocked to 1ghz and im at 43% battery with 12h 34m of usage today. General usage off and on, texting all day and some phone calls/app usage etc. The problem is I can easily have days where I only get 12h out of the whole battery because I'm on the phone all day doing things.
Even something as small as signal strength where you use your phone can effect your battery life numbers. take every battery life screenshot with a large grain of salt. The best thing about the battery meter in 2.3 is that it at least shows how long the screen has been off so you can tell when people just idle their phones to claim huge battery life numbers.
That is one of the things I really liked about CM7. The battery graph.
Never said I was a heavy user. I quantified my average use by time and activity. Still, with the same average use, my battery life on CM6 far outstrips CM7. They're both excellent roms. I like many of the new features in CM7. However, the battery life and GPS troubles influence me to continue using CM6 as my daily driver.
Once I figure out how to replicate the battery life or CM7 hits stable, I'll gladly upgrade.
Try out some CM7 nightlies.
I'm on nightly 12 and I get excellent battery life: as much or even better than stock. GPS also works without a hitch. I remember my first lock took like 20s max. And navigated without a data connection using Navigate (voice guided) for 45 minutes without a hitch. After that may bat was at about 79% I ended up not charging until 15 hours later.
So yes, Nightly 12, atleast for me, is solid. And I will never upgrade until something better comes along.. like the Meizu rom.. your mileage will vary though.

Cyanogen....the best rom out there and it gives you amazing battery life.I'm using cm 7 nightly 26 and I can go a whole day on moderate use.
Sent from my CM 7 Monster Evol.
So every time I read a battery thread and someone mentions how well a ROM is on battery the pictures posted always show that the user is barely using his phone. They show a picture of their phone that shows it being unplugged for over a day and everyone gets excited and thinks their phone will last over 24 hours on a particular ROM or setup. Then when they do not see the same results they can't figure out why.
The answer is, as long as your device has no apps or bugs keeping it wake, if you don't use it, it will last. My EVO 4G could last 24 hours if I didn't touch it. The thing is once you started to use it it wasn't long before it was over!
So I would like to see pictures of battery life from people that actually use their phone so we can see what Roms truly are the best and what battery tweaks really do work. I am not interested on what Rom sleeps the best. I use my phone and don't need it to sleep for 2 days. If you cannot get to a charger within a 24 hour period, you have something else going on that you might need to address, lol.
Please post what Rom you are running and anything that might be installed that would effect battery life for good or bad.
I am running my phone stock. It has never been rooted. Below you will see after 12h/44m unplugged my battery is down to 26% with 4.5 hours on screen time. I was on wi-fi the entire time and also have an Airave in my house so signal did not play an issue with this stat.
I keep my phone on auto brightness, GPS is always on (doesn't effect battery like people think, only uses it when it needs to) and have my weather, news, and Twitter apps syncing every 3 hours. I have no battery hacks or software running. I also use ADW Launcher EX as my launcher. I know some launchers are better then others with battery and it doesn't seem like ADW drains much at all.
I look forward to screenshots and setups from other people so we can truly see what setup, Roms, and tweaks work best for battery from people who truly use their phone.....
On a typical day I get about 12-14 hours from 100 to 0 battery charge.
I kinda agree with op. I ran stock for 2weeks and i got the same performance as him. It was superb

It looks like your phone barely sleeps. It's awake most if the time. Seems like you need a replacement phone or try a different kernel.

no, not at all. i guess i really need to figure out what is causing my awake time & wifi statistic to not be on par with my screen on statistic. i've had my phone for just over 3 weeks now and learned to sort of deal with it, but after reading a few more threads about it, i'm concerned again.
This is what i currently have syncing:
2 gmail accounts - set to push
2 pop3 accounts - set to pull once a day
1 google calendar account - auto sync unchecked
facebook - 4hr refresh interval w/ notifications active
twitter - 4hr sync interval
and all native google apps that may sync in the background
This is what I got:
Here's mine. I didn't use my phone as much today as I usually do. But screen was at max brightness when I was using it and WiFi was only connected while I was at home. It was on but off except when searching for open signal otherwise.

and it shows 3% accounts for calls,unless for "load of" you mean texts and games
You guys are also forgetting about screen brightness and also signal. If you are in a low signal area you will get less life.

I haven't ever had FANTASTIC battery life like I'm seeing from some folks around here... when I first started on Starburst (I didn't keep stock for more than about four hours), I was at around 70% at the same time. I'm currently on Calkulin's 2.0.0; about to revert to Starburst and see if it's ROM-related, now that I've given Calkulin's about a week with a calibration to no effect.
I'm currently undervolted by -75 on all steps, and this seems to have made it WORSE if anything, which I didn't think was possible for undervolting to do. I've been monitoring things fairly closely with Watchdog, and nothing jumps out at me. The phone signal in the pic doesn't look good, but I've been in all the same places as I was when I was getting much better life.
What interests me is that I'm seeing absolutely no usage-based change in battery life. Until that sudden dip you see up there, it was going down at the exact same rate whether I was using it or it was sitting on my desk doing absolutely nothing.
That dip started after I played Fieldrunners HD for about ten minutes during a break at work. After I stopped playing, battery life went into a continuous plummet.
I use Tasker (extensively) to keep things in check; generally speaking, nothing is active unless it needs to be, except for Wi-Fi which is always active as it's my primary method of detecting my locations.
Am I missing something simple-stupid here? If not, anyone got any ideas, assuming going back to Starburst doesn't magically fix it?
Not sure if this will help, but improved my battery.
(1) go to your email setting for each account and change sync update, I believe by default it's set up to check every 15 minutes. With 10 email accounts, it took a toll on my my battery. I changed all my accounts to 4 hours.
(2) best way to kill a task is by holding down home button, going to task manager and kill from there. Market task killers were making things worse for me.
Hope this helps.
Thanks for the thoughts! Sadly, neither of those really apply in my case. I stick with with the default Gmail app, which is all push, and I don't use task killers at all.
I'm running the stock rom with a custom kernel. I did notice that as soon as I went from stock to a different kernel I started to lose battery life. Maybe its something Samsung did? I am still a novice with Roms and what not, but nothing like this happened on my original Epic or my Hero. Maybe the yellow triangle isn't the only thing Samsung put in there.
Maybe the aggressive undervolt is causing your phone to ramp up to a higher state to perform the tasks? That drop is steep with how little screen on time you have

For as little as I know, that certainly sounds logical. I still wasn't getting as good as I would've expected even the UV, though.
I just flashed the EK02 modem with today's wonderful developments; I'm going to wait and see if that gets me better reception and thus better life. If not... now I'm not sure whether to try the new ROM first, or scale back the UVs. I want to try one thing at a time, since it's not urgent that I have good battery life ASAP. This gets me through my day, currently, more or less; I'd like to try and find my root cause so that I'm not just trying things wildly in the future.

Well, the good thing is that as of today, its possible to return back to bone stock and start again so you can mess with a few setups and see what works best for you. I have found that this is the first phone that uses the frequencies well. I haven't undervolted at all yet and I have had great battery life. I did the standard delete Sprint bloat, Social Hub and associated apps, Maps, etc. Also, get BetterBatteryStats. It may give you some insight into what's happening.

Then update to EK02
Got very slightly better today after flashing the EK02 kernel. 23% at the same time instead of 18%... anything could account for that 5%, though, so I don't really think EK02 had any effect on this. Zedomax kernel with stock voltages is next.
CPU boots pro
(From the market & assuming your rooted)
Settings
~Screen off profile max800 min200
~GPU to Conservative max1000 min800
~Nitrous Widget GPU to on demand max1400 min1000
What this should do is downclock your device when on standby by alot. Second for phone calls and daily stuff a clock of 1k will be silky smooth and be a small downclock. Third when you set up the nitrous widget and activate it you will overclock to 1.4k which is stoopid fast my quad score is at 1.4k I get 4500 scores at 1.6k oc but forget batt when I'm using the nitrous. I like too personally keep my phone at a clock of 800 for daily phone calls and web surfing... if I play a graphic intense game ill oc it with nitrous and not worry about burning up my phone because if I set the phone down it downclocks as soon as it stands by and will pick right back up when I'm ready.
Hope it helps here's pics.

If you're talking about the page I think you are, it'll have to wait until at least morning. I just did a full charge.
To wit... I spent 43 minutes on a phone call, and lost almost the same as what I normally lose in that same time period. 6% for a 43 minute call; I'm averaging 5%/hr loss doing NOTHING.
@Dchibro, assuming that's true, what would it mean for me? Does it give me a solution?
So, doing a bit of my own detective work... I've had Watchdog installed for about three days, with aggressive monitoring. I was almost immediately getting a bunch of alerts for two processes:
I initially whitelisted them through Watchdog, dismissing them as system processes that unavoidably needed to run. However, the comment from Dchibro got me thinking and sent me back to those, and I started Googling around. Here's what I've turned up so far:
http://goo.gl/Hsvej (HUGE thread on the issue in SGS2 forums. Haven't had a chance to go through all this yet.)
http://goo.gl/kUcqx (SGS2 forums.)
http://goo.gl/mlWW4 (Nook Color forums.)
http://goo.gl/mNiId (My Google search results.)
Gonna try some of the suggestions on here and see what I turn up. For now, I'm returning to stock voltages, implementing a bunch of those changes and keeping everything else as it is now to see where I end up. Phone will be charged to 100% before bed tonight, and I'll post sometime tomorrow with my findings.
Wish me luck!
So, in stead of waking up to 50% this morning, I woke up to 86%! Which is the same I went to bed at. Six hours of sleep, not a single percent lost. If nothing else, I learned from all this that I can reboot the phone when this bug hits me and and get away from it.
As I suspected. Your Watchdog shot clearly shows that you are/were (sounds like a reboot solved your issue at least temporarily) suffering from the Android OS bug. This bug presents itself most prominently in the suspend and events/0 processes. Unfortunately, a conclusive solution has not been found, but there are some things you can do to hunt the problem down.

I charged too 100%, shutdown, then charged to 100%, powered up and used the phone very sparingly since. Battery is at 91%

Definitely seeing a bit of an improvement, here.
Watchdog alerted me to the suspend and event/0 stuff again about an hour ago, but I quickly rebooted and nothing seems to have come of it. I'm going to try to make a Tasker profile to do this automatically, kinda like Viper's LoS script.
All in all, I'm considering this a mostly satisfactory alternative to draining 80% of my battery with almost no use in eight hours.
Well folks, I took time to study our G2 battery to really see what is killing it. After testing it on different roms i have come out with something that can save your battery for a while before you think of replacing it.
On a general scope these are the main factors that really drain your battery:
1.3G data connection
2.Screen brightness
3.Rom type(mostly sense roms)
On 3g, if the user has a wireless network nearby i suggest you connect to that for your browsing and all that, there is no need using hspa when you have a WI-fi network working great, 3g networks drains the battery faster than you think i tried it and i saw that the WI-fi use was very slow in draining the battery up to the point i switch to 3g. IF your thing is voice calls i still don't see how good and different 3g is from 2g "it's not like you are recording an album over the phone to need such voice clarity" remember a good battery life affects your phones performance in a great way. these photos tell the whole story..

i used the wi-fi for about 12 hours and when i switched to 3g it drained in 2 hours
For screen brightness you will notice that every time you check battery usage your screen always has the biggest share of the consumption. You have to reduce your screen brightness to 30% or lower or put it on auto-brightness that's about all you can do about it.
Also your rom and the kernel it comes with are a huge factor in battery consumption. On a general scale i have noticed that sense roms are the big killers of all just see
in 51 mins of no use at all just screen off the battery drops to 81% i have never had above 9 hours of use with any sense rom
Other things like gps also drain your battery, so if you are not on "MAPS" just switch it off to save your battery. Also keeping your cpu clock speed at high points drain the battery a lot try to use apps like setcpu to control the clock speed and set profile like screen off to keep your cpu down when you are not using it, and use cpu governors like smatass, ondemand, conservative etc
Also the trick of draining your battery completely and then recharging it in intervals of 3 months or more help enhance battery life,
do not leave lots of apps running in the back ground they also drain you battery alot :good:

About the sense roms, even though i agree it consumes more battery than AOSP, they are not as bad as u say (at least not all of them). I use a sense 3.5 rom and with regular use i get about a day and a half before it hits 20% (80% consumed) (This is on 2g, with wifi on... when with data on, i still get at least 22 hours). I know it comes down to settings and usage, but just saying, its possible to get a lot of battery endurance with sense.
If anyone is interested in more detalied information on my settings and usage, feel free to ask me (through pm if possible)
Nice review though, thanks for sharing!

This is impossible if you havent got a problem with the rom. I have been using all kinds of roms with my Desire Z. The battery life is not that much different on sense and aosp roms.
I am using GenY Beta5 right now for example. On standby mode (only gps is disabled) it can go more than 2 days! A stock optimized 2.1 Sense rom can go even more than that.
For battery life problems I suggest using an app like Better Battery Stats and see what is causing your phone to stay awake. It is easy to see what eats your battery.
Other than that as you said, whatever rom you use Screen will eat your battery the most. Overclocking will obviously eat more battery too. Using 3G instead of 2G will use more battery. COnstant Wi-fi activity and gps are battery killers too as you may guess.
The rest is how the user uses his/her phone.

All you are saying are basic stuff everyone knows about power consumption, and all that you have been testing are YOUR results, what you are saying now are absolutely no facts, and some are wrong. You're saying sense takes more juice? Well since IceCreamSandwich it doesn't really matter. Are you sure your battery is properly calibrated?
After installing a rom you shouldn't put the phone on a charger, but just use/leave it till the battery has 10% left. then charge till its full. By prefer you should do it another time and then it should be calibrated.
Also you forgot to add the radio. The radio is also important, if you got a proper radio for your provider/rom, you can easily get more power out of your phone. If you have the wrong one, drains can be high. The extremest example I can take is my old HD2. Which had a radio not compatible with the version of android and the battery drained from 100 - 10 in 3 hours.
Now look at my stats of my DesireZ, running Gen.Y RC1(Which seems to be using more battery then the B5). I attached a screenshot. The battery is totally stock and not an extended one. I used it yesterday at home when I was busy with my car(whatsapp, mail, google), at the evening I played some games. Before I went to bed my battery stats was 60%, when I got out of bed this morning it was 59%.
Also I think the topic should be in "general" since its talking about everything, and I can't see how this is rom development.
Thanks for adding up guys,but I am sure your batteries are quite fresh that's why you have very good batteries,people like me with aging ones who still want to use it for a while. I had to wipe my battery stats a few times to calibrate it. And if your read things very well this was meant for guys who really don't know the does and donts about battery usage yes it's basic but people still ask these questions in dev sections. I did not add radio because that thing does not work well for everyone and it's still an easy way to brick your phone most of these radios were made with USA service providers in mind ,people have complained about having serious issues with battery and connectivity when they Change their radio and if any one is even reading this then I don't think that person even knows what the radio is so why not do the basics than brick your phone in an attempt to go high .....to the big boys who know all.... you have to know that there are still guys out there without rooted phones facing these problems so radio is the last option......

If their phone is not rooted, how can they have a custom rom then lol. I think if you want to use a custom rom on your phone you should read everything and not blindly start everything. Also flashing a radio has risks, but not really something to worry about if you do it right. Its quite easy and as long as you stay on the right path you are fine. If you want to make a proper thread about battery consumption you should include the radio thing. And also post it in a place where it belongs. You are right that newbies don't know everything, but if we should do everything for them, you get even more newbie questions. They need to put some effort in it like we do.
also you have not added the tricks like changing the advanced wifi to always wifi when screen off....

Ditch lean kernel. Do you have Chrome installed? It has an undocumented feature. It does unspeakable things to your battery. There seems to be at least a little incompetence going on in Chrome's code.

What version of CM10 are you running? I'm giving it sometime, but just flashed CM10 M1 last night, and am wondering if a change from cyanogenmod's kernel may help with battery. Got about 6 hours of lite-moderate use today on my I747
What things are you running in the background (NFC, GPS, vibration, haptic feedback, etc.)? I'm running CM10 9/15 nightly with ktoonsez's kernel with a 1.9Ghz overclock and my phone lasts from 8 in the morning to 1 in the morning. Today my screen's been on for just over 4 hours.
Another thing to check for is are you located somewhere where you consistently get good signal? If your phone is constantly reacquiring 3G or 4G or constantly searching for signal it's going to cause a severe drain on your battery.

I'm using SmartassV2 with SIO. I know I'm old school with SmartassV2, but comeon the name alone is worth whatever marginal performance increase I could get with some of the newer governors.
Well I notice that when I'm on screen, my battery drains like nuts. I slept 8 hours and I went from 100% to 88% which isn't bad at all, however if I'm texting or w/e, checking the web (keep in mind everything is off, I'm not a retard, and my brightness is at maximum low), battery eats like nuts. Is there a kernel or specific rom I should install?

This kernel? It says that if you install it, and you want to go back to stock, you need to reinstall the drivers. Wtf does that even mean? Where the hell would you even find the drivers. Sounds too high risk lol
I am running the latest CM10 build and my battery life is terrible as well. Wednesday night I was about 75% charger before bed and when I woke up, less than 7 hours later, my phone was off with no juice. I tested it again last night with about 85% left and it was dead again this morning. I have the same app installed that I had installed on stock and did not have these issues. I absolutely know and understand this things differ from person to person and settings to settings, but I am not sure my settings are that different from when I was on stock. I fairly enjoy the ROM, so I am just dealing with it.
Well, I've charged my phone to 100 last night, wiped battery stats (still on lean kernel), and i put my phone to sleep, and it drained only 8% which is very good (7 hours of standby). Now where my battery drains like a **** is during on screen time. I've put brightness all the way down to low, but I see people who get 20 hours with 5 hours of screen time. I could only wish to get such battery life lol. I wanna try that k747 kernel but I'm scared about losing my original USB and and **** drivers and I have no idea how I would go about restoring them if I no longer like the kernel lol.
CM10 battery life isn't that great. There was one nightly build that had outstanding battery life, but I can't remember which one it was.

If you both read his OP all you have to do to get the original drivers back is Reflash your ROM that has those drivers. It isn't a huge deal also to the guy going 80%-0 overnight, you have an app eating processes in the back destroying your battery.
