Question regarding cell standby and battery life since a recent upgrade (eh03_sc3_0.5_full with the KGB 1202 kernel). I did the upgrade on 12/6 coming from UKB, pbj50 kernel and ed05 radio.
All is working well, including better reception, though I have noticed substantial battery drain recently despite all other settings being the same (wifi off, brightness low, debloated and frozen apps with TBU Pro, etc, etc.). Ive lost probably 40% of my battery capacity and am near dead by 5pm with minimal call use. I wiped battery stats, flashed with a full battery, *228 after modem update, gave it two weeks, and so forth, just as I had with every other upgrade.
I see in battery use that cell standby is 34%, followed by display at 20%, calls 6%, 5 hours after boot. Is this excessive for the cell standby ? Would another radio work better ?
IMHO, eb01 was the best radio for my use, followed by ed05 and ec09. Possible that the current radio isnt working properly ?
do you use an OC/UV app? like SetCPU? perhaps setting a profile for screen off down to like 400/100 would work for you? I found similar issue with my battery using KGB 12.12... i reverted back to KGB 11.27, and did notice less draw...
of course I failed on the first attempt and had to reflash the rom and all... but I'm a flashoholic anyway...

My wife is fully stock and I'm on the Ultimate KangBang Rom. Both have the ED01 Radio's and no 3G issues that we are aware of.
Since the update, we are both getting far worse battery life.
I have not touched the voltage controls in the rom.
Anyone have any ideas?
Could this be related to a 3G issue we simply are not seeing?
Should I (as she is not rooted) try to reset the battery stats after next full charge?
Should I call 228 to make sure everything is kosher on that end?
***************
Update:
I unplugged this morning at 7:30ish. 100% battery.
I started this thread at 10:30ish. 75% battery.
~3hrs, light use, lost 25%.
I hit both options in *228 at 10:30ish.
Its now 1:30ish. 71% battery.
~3hrs, light use, lost 4%.
I think the update, in general, just screws up your 3G/roaming etc. This was already known with other issues Verizon had over the last week or so. This seems, to me, as the most likely cause of battery drain.
I'll will come back later to say if anything changes. Also, need to see if wife ran the *228 options on her phone and will report back if findings are similar.
Hey superchunk,
I have a somewhat related post in the general section, and am finding low cell signal together with Google location services are giving me 4-8% batt loss per hr. See below. Also make sure to toggle airplane mode once per boot to workaround the 50% TWOS bug.

Check what apps you have installed. After I did the full update to ED01, and then replaced the kernel with Imnuts' -100 undervolted kernel, I was getting great battery life until I installed the full Skype client. Even logging out so the program would quit, the battery started draining upwards of 10% per hour, even when the phone wasn't being used.
It seems Android in general, and 2.2 specifically, is pretty vulnerable to errant battery drains. Worst part is that it didn't stop after I uninstalled Skype, so I had to go through the whole process again - back to DL09 and then update.
We've always had google services on (before and after upgrade), so I don't think that has anything to do with it.
Neither of use have Skype and no other apps have been installed anything new (don't use skype), but that doesn't mean something old has a new undesirable effect.
So far, I've ran the *228 options and will see if that helps. I'm thinking we simply haven't noticed 3G dropping and really needed the updates to programming and roaming.
Having a phone constantly searching for its best band will cause quicker than normal dead batteries. This is one of the reasons the Thunderbolt is getting so many negative marks for battery life, LTE just isn't there yet.

Seems the Google location services battery drain was much less of an issue with 2.1.

Have you charged to full and wiped bstats?
So my settings aren't anything unusual on my tbolt, but right now my battery usage reads as follows:
3hr 36 min since unplugged
82% Android system
5% cell standby
4% voice calls
4% idle
3% display
There's a laundry list of items under android system, and I'm in a pretty poor signal area. I always though signal-searching went under cell standby though, is that correct?
Additionally, when my e-mail accounts sync, I always assumed that would go under cell standby, but there's something in system for syncing as well, would it go there instead?
thanks for the help
*edit - battery died after 6 hours of almost no use. phone was also getting quite warm. I also want to point out that this doesn't happen normally and I've only noticed it a time or two in the past.
What ROM and kernel combination are you running?
lean kernal and das bamf 1.5
I would backup your applications and data, then reflash the ROM and see if you are getting the same results on a stock kernel.
I was using leankernel too and got this same problem. Or rather, as soon as I flashed lean kernel, I noticed that my phone would die quickly in standby, regardless of what speedtweak.sh mode I was in. I was getting something like 4-6 hours of light use out of my phone with before it would die.
As soon as I switched back to the stock bamf 4.4.7 kernel, my battery went back to normal, draining to 30% battery after 10 hours of light use.
I don't know why, but the ROM and kernel just didn't play nicely for me. Try reflashing back to the stock bamf kernel and see if it helps.
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.
courtesy of my rooted bolt
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.
Hi. I know there are tonnes of battery related threads out there but I would appreciate if I got some personalized help.
I am running Trigger 3.2 Final with Bali v1.8.4 and the JK6 modem.
I have gone through all the modems available for Froyo and JK6 gives the best battery life for cell and data. No overclocking or anything.
The problem is I get extremely bad battery life on data on all modems. JK6 seems to be the best of the bad. With data off, I can get 20+hrs with light phone usage, but the moment data is turned on, the bat percentage just drops like a rock. If I enable data and browse the net with Opera Mini (no flash), a 100% charged battery can be reduced to to around 30% in around 1 hour. Sometimes more, sometimes less.
If it is the battery needed replacing, why do I get excellent cell life with no data activated. Bali is supposed to be battery efficient, but I am bleeding power. I bought those cheap knock off batteries from ebay and get the same results.
Brightness is on lowest, syncs are all off and email checks every hour I think. Nothing else I can think off can be chewing the battery.
I have calibrated the battery many times and makes no difference. I should also mention that I had worse battery life on the bionix roms.
On battery use,
Display takes up around 83%,
Cell Standby 11%,
Idle 5%
What can I do? Is there an app that will tell me if I should replace my battery or anything. I am all out of options right now
Bali Is The Problem
I just read about this same problem from other users, the Bali kernel eats up a charge cycle extremely fast and has even caused major over heating problems!
My suggestion is to go to a different kernel or change the ROM completely to something less power hungry
it could possibly be the batttery itself, mine did this a while back and replacing it helped, maybe even upgrade to the extended battery if a little more bulk doesn't bother you it's a great option try a different kernel, i use Bali and am not overclocked with the JK6 modem and text all the time at school I then got an iPod touch and stopped using my phone for music and it saves me an average of 30% battery 0_o idk why but oh well
I'm running the latest CM7 nightly, and I've noticed that cell standby is draining the battery. In battery usage, cell standby is anywhere from 50-80%, depending on how long the display has been on. And this is with a clean install (no apps, no google account sync).
The thing is, I'm traveling abroad right now so I don't have cell service but I do have wifi access, so I don't want to just put the phone in airplane mode. With other roms (I've tried stock and unnamed) there doesn't seem to be this issue.
Any ideas? Thanks
I believe it has no real effect on the battery life. It has been discussed many times and you should be able to search for it on the forums.

Is your battery ACTUALLY draining?
Remember, everything in battery stats is relative - if you reduce one drain source, the percentage for another will increase.
Cell Standby is a fairly fixed drain source - the only way to actually reduce it is to move to an area with stronger signal or put the phone into airplane mode. If it's high percentage-wise, that just means your other drain sources are very low.
Thanks for the tips
The battery did seem to drain faster with CM7 (not just based on the percentage of cell standby).
One thing I noticed is that with CM7 the phone signal bar in battery usage was almost all red, but with UnNamed it was mostly yellow. Could this be why the battery seems to drain faster with CM7? Would flashing a different modem help?
