I'm currently running Liquid Smooth 3.0 and losing battery life considerably. If I flashed the latest radios... could this be the reason I'm losing battery life so quickly?
Wow where to start, depending on your phone settings after you flashed your new ROM could be a direct drain I won't get into that since i don't run your Rom on my phone, could be kernel settings again don't know the kernel used or settings on kernel. They made a thread that reads like a book on battery drain so needless to say there are many factors. Suggest you hit up liquid users in the Rom thread and ask direct questions about settings. Signal strength can play a pretty big factor in battery drain, I get about -84 at my house and it drains at normalish rate but at work I get -100 and get about 4 hours less battery. Always remember every phone is different what works great for mine may drain yours.

Try using SystemPanel by NextApp
It's worth the money cause you want to use the paid version that allows you track your history.... don't forget to turn it off after you find your battery hogger cause the tracking itself is a battery eater.

ive had my xv6800 for about two weeks now and im still trying to get my power settings tweaked right. granted, i ahve been playing with it alot and probably doing some things that arent conducive to long battery life. One problem is that i dont really know what to expect, so if everyone could please post what they do, any tips/tricks to increase the battery life that get out of it.
also if anyone does think they get good battery life out of theres, what they try to avoid doing on it, that gives you such good life.
thanks

The brightness of the screen is a factor. Try lowering it if possible.
Disable active sync, bluetooth, wifi, and beam when not needed.
Using the GPS drains the battery quick. ( results vary )
Push email also assists with battery drain.
Put your phone on standby when not in use.
Also the extensive use of PIE and Windows Media Player also assists with the drain of battery.
Last if you have poor signal strength this can also be a factor for battery drainage.
There are others out there but these are some that I encountered and learned live with.
There is a battery hack out there that can help you with your battery life. I don't know from the top of my head but search for a registry battery hack.

I think [email protected]$ hit the nail on the head. Everythng stated is a sure fire way to drain your battery quicker. I just got my Mogul and have been playing with it quite a bit even though its pretty much the same thing as my Apache but none the less all those things will drain your battery. I have this thing going on 2 days with very little battery left with minimal use of phone options.
I had previously not had data, so i kept BT always on, never went past 80% with texting and using some programs throughout the day. Now with data, for the last 2 days, wow, down to 20% both days. I turned off BT to see if that can save a little and will turn down the screen a little (was on 100%).
Hi everyone, this is my first ever post on the forums so don't be too harsh on me lol anyways, my question is what is the best ROM + radio + kernel combination to get the longest battery life out of my stock thunderbolt battery? Currently I am running DasBAMF 2.0-5 the MR2.5 radio and the dream kernel. I haven't really noticed a huge improvement in my battery life since I flashed this rom a few days ago. I have seen people who claim to be getting 10-15 hrs on one charge. I don't think I need that much because I charge overnight every night, but it would be nice to know how people do that. also, what are your thoughts on juice defender? thanks!
I am currently using CM7 R1.2 w/ the MR2 radio and I get very good battery life. 10 hrs plus with minimal use on the regular battery.
I've been running Gingeritis 1.0 with JuiceDefender Ultimate and I've been getting anywhere from 16-20 hours on the standard battery with regular use (facebook, email, words with friends, browsing, etc.). What I find most helpful with this rom is the brightness slider in the dropdown quick settings. Unless you're outside on a bright day or it's absolutely necessary, keep the brightness as low as you can comfortably use. I've found this to be huggee in the ongoing battle to get better battery life.
And if you can tolerate life without 4G, use an LTE toggle app to keep your phone on 3G. This also helps a lot.
i like the Inj3ctTh3ory rom so far.
It looks to me that all MR2 radios use more battery. The best battery performance for me was on BAMF 1.7 and MR1 radio. I would use 2 to 3% battery on standby overnight, with the phone on 3G. I am on BAMF 1.8.6 now with the OTA radio and the overnight battery usage is up to 10%. I will keep testing, but I think stripped MR1 ROMs have the best battery performance.

BAMF 3.0 RC4, imo 3.4.0, OTA MR2 Radio... constant 40-45 hours on the extended battery.
How I maximized my battery
In terms of my battery I just wanted decent battery life without using a tone of extra apps to do it. I'm using the CM7 RC 1.2 with the MR2 Radio getting about 20+ hours of battery with standard use. I am not using Juice defender or any battery saver apps. I am just using Tasker to turn on and off my Wi-Fi when I'm not at home, because I hate doing manually
One thing I did do to maximize my battery life is after I flashed my new ROM I did the following after searching multiple forums for battery optimization methods
1. Charged my Battery to 100%
2. Did a Bump Charge Cycle 4 times, and then turned on phone
3. This step is probably key. Downloaded the Battery Calibration App. You can find the app in the Android Market.
4. Plugged in the charger until the Battery Calibration App read 100% and 4200+ mV. I found that even after bump charging my BW battery widget would say 100% and the led would be green. However when I go into the Battery Calibration App it would say 99% and the mV would be about 4160. I just plugged it in and waited about 30 - 45 minutes and it would finally be fully charged at 100% ~4200 mV.
5. Press the Battery Calibration button in the App to clear the batterstats.bin and unplug the phone. Do not shutdown or reboot.
6. Let battery drain completely without plugging it in (USB and AC)
7. After it completely dies Charged battery straight until 100% with no interruptions.
I'm getting good battery life without having to use juice defender or anything, and that's also with streaming bluetooth music everyday driving to and from work for a total of 1 hour. I also keep the radio at 3G the entire day unless I really need high speed data. And unless I'm in the car, Bluetooth is turned off. I'm pretty sure these steps should work on any rooted phone regardless of ROM.
I tried many different rom and kernel across the forum... I dun see any differences in term of battery life, just go with the one you love.........weeeeeeeeeeeeeeeee
My bolt gets better life running Ziggy's kernels for some reason. Not sure why, but it does. I've tried every sense ROM out there. +1 on the post above. Go with what works best for you and the way you use your phone.

I've found cm7 (cm7 kernel) to have the best battery life for me, getting up to 28 hours with light use and no 4g. I find the auto-brightness on cm7 to work much better than on any other ROM I've tried, and for some reason all other ROMs drained the battery around 50x faster while idling. I can leave my phone unplugged overnight and expect to lose maybe 2-3%.
There certainly is no universal solution though. That is the only certainty
Whatever rom/s you test with...make sure you try various kernel versions (lean kernels mostly) to find what works the best.
I've tried them all,
GINGERTH3ORY V5.0 DreamKernel is my favorite one. it's super fast and very responsive.
Battery life is best on this one .
I use speedtweak batt saver ondemandx.
I'm on Bamf 1.8.6 remix right now with the OTA MR2 radio and getting about 14 hours on 3g all day and 8.5 hours if on 4g all day. Still looking for something better.
I have had a lot of luck with Inj3ctTh3ory. I have only had it now for two days but I'm already impressed with how long the battery has lasted. I have not experimented with any Kernel/CPU combo's yet but it's performing so well now I might not mess with it.
ROM and kernel linked in my sig. I'm using the 1.4GHz extreme UV with interactivex speedtweak, I love it. Bulletproof stability and with mild/moderate use I can make it through a 9hr work day with 50% left on the stock battery. 4G left on, everything syncs every hour. I don't get 4G coverage at work, I don't know if that helps or hurts, but I do leave it on.
Simple question for all the experts...
If two different Roms are running the same Kernel, should the battery drain be that much different?
Im running REZRom currently and thinking about switching to Bamf 2.1. i'm sure both roms are smooth and fantastic I just want the one with the best battery life.
Any advice would be great, thanks in advance.
You should get good battery life on either. That is depending on your usage and setup of course.

Battery life with same kernel should not vary too much from ROM to ROM. Depends on how much "stuff" is running in bakground that might be using the battery up. The kernel makes the biggest difference since it controls the whole system. I am personally using Scotts CleanRom Developers Edition (Senseless) and it is great! I get a solid 13+ hours with moderate use (some calls, lots of web, and a few games) and thats on 4G for 11-12 hours of it! If you use wifi you probably could squeeze another hour or 2 out of the battery...
This is on clean rom dev edition. 2 hours screen on time so far with standard battery. I use 3g normally unless I need 4g. I also use juice defender ultimate and keep data off while not in use.

While there are a number of tweaks and apps you can use (like SetCPU) to improve battery life, it's true that the kernel has more to do with battery life than that ROM itself.
Sometimes a rogue app can prevent the cpu from idling or prevent the phone from entering deep sleep mode. This happens on mine occasionally, and you can usually tell from the extended battery graph because the phone will show as awake for large periods of time, even when the screen is off and it should be in sleep mode.
Plenty of focus on all ROMs have been performance and battery life has not been so good. Request a ROM that focuses on battery life, for those that are away from a charger during a 14 hr. work day.

Have you thought about purchasing an extended battery ?
Or
Simply limit your processor, brightness, radio connectivity, and use am android firewall to limit which apps can and can't use data/WiFi. Also ensure you have good settings in your task manager

I get 2-3 days out of my 2400mAh-battery, using MIUI and the forbidden kernel.
I can't complain at all about battery life.
Everything runs silky smooth at 192/1180mHz - xondemand
A little undervolting and a little gpu underclock.
I think poor battery life is more "user error" than something to call dev attention for.
There are plenty of guides on how to maximize battery life on the web and on xda.
2 tips from me, because many guides get it wrong or fail to mention:
- This app lets you schedule autosync. With some care and thought when setting it up, you can be always up to date without your phone snycing all the time. If you need to be in second-precise sync-though, it's not for you.
- Wifi off @ screen off is a myth. I have set my wifi to be on all time for months now and haven't noticed any decrease in battery life. If anything, it's better now.
I use mwakious, forbidden kernel at 1512 mhz and an anker 1900mah battery and get about 19-24 hours no problem
Try using Juice Defender too
I've also noticed keeping wifi connected all day is drastically less harsh on the battery than 3g.
I get awesome battery life with mentioned banned kernel and meanrom. I just switched to another rom and not sure about battery life there yet or i'd share
Hello,
I was wondering which rom you guys could recommend for better than stock battery life? Seems like a lot of the roms are tweaked for smoothness and speed not battery life. Currently on d3rpICS but the battery life isn't so great...barely getting 8 hours with 1 hour on screen time. If anyone could point me in the right direction I'd appreciate it. Thanks!
Meanrom ICS comes to mind. Your kernel can also play a role on battery life too. Overclocking will drain your battery, so will certain governors. Experiment around a lil bit to see what settings work for you.

How are you only getting 1 hour of screen on time? I suspect something else is the issue. Are you in an area with poor signal reception (that is usually my worst battery drainer)? Or maybe you have a runaway app. I recommend that you download Better Battery Stats XDA to monitor what apps are eating your battery.
Maybe you could try a fresh install of the ROM, but leave off the extra apps and see how it runs.

No I'm not in an area with poor reception...and the ROM was a clean install I haven't even put anything back on. I'll give meanrom a try and see how that goes. Thank you.
Coolexe's kernel UV's the screen, i'm getting 4+ hours scraping 5 hours+ on screen tme ... note not using 3g, i find 3g canes my battery.
tips.. stop the media service in running apps 'the one that often gets stuck restarting' .. mediadbmservice or something, i can't find anything that doesn't work after disabling
running 1188 -ondemand, cpu1 not forced always on and gpu3d/2d/266/200 using 'kernel tuner' and a small undervolt.. all 1xxx up to 1188 frequencies set at 1.0
I also stop apps that i don't need after their use, including 'kernel tuner', I know your not supposed to but i haven't seen any ill effect so far.
