I've been running the latest BAMF DESENSE . By going through the settings and setting up set CPU with some good profiles I've been able to push my TB through the day with battery to spare.

Imoseyon's Battsaver leanKernel with TeslaCoil has served me well.
Today I had about 13 hours of uptime (with ~5 hours of being powered down,) and about 3 hours 50 minutes awake time. Pretty good, I think.

Thanks.... I think ill give teslacoil a try .... Any other ones ....

I've been running the new BAMF 1.6.3 remix with the new included kernel and its been about the best I've tried so far.

My problem is that I work as a field engineer, so I spend a lot of time in plants using my phone as a tethered wifi internet connection (in fact, I'm posting from it right now). I have yet to find anything that lets my phone last more than an hour while connected to 4g and using Wireless Tether. I realize those are probably pretty extreme circumstances, and I get by since I bring a wall-charger with me to plug into whatever electrical panel I'm working at, but I can dream, can't I?

the bigger question here is what kind of plant lets you take your cell phone out around the plant? Those are supposed to be no cell phone areas

Exactly. The majority of my work is in "big 3" automotive plants, and they have "no picture" rules, and "no walking and talking" rules, but cell phones aren't banned.

Yeah, this sounds like me. Battery drains like crazy regardless of what roms/kernels i use. My radio, in CM7, is currently set to CDMA /EvDo Auto. Is there a more efficient one that wont put me down to 2g speeds?

Wait, does that awake time mean screen time? It only takes me 2 hours of screen time, at most, to get to 63%

Are you overclocking the bamf 4.4.7 kernel at all or running stock speed?

uptime: time the phone has been powered on
awake time: time the phone has been on without going into sleep mode (time it has been doing stuff)

Leankernel extreme with setcpu limiting to 1ghz. Also, screen off @ 245mhz. Runs great even when playing music. I set to 3g using lteonoff app but it doesn't make much difference if you're going to be leaving on an app such as skype that constantly uses data. I have set everything to sync manually except for email. At lest it runs all day with light to moderate use now instead of draining 5% per minute from just check my email. My backlight isn't set past 40% (can't see the screen if I'm outside otherwise.

CM7 MR2.5 bat issues

Hello to all you great people! I am not new to this site but I havent posted much or at all. This site is increadible and has taught me a ton about what a droid can do once you know how to use it. Thanks everyone! Anyway I have a question that I would of posted in the CM7 dev thread but I dont have permission since I havent posted much. Is anyone having bat drain issues with the newest build (RC1.1 MR2) using the GB radio 2.5? I have lost over 10% bat life in 25 mins while in airplane mode, no data including wifi and the screen was only on for maybe 2 or 3 mins. It may be a problem on my end but I just wanted to see if anyone else is having an issue with this. Oh and thanks to all you devs for doing all the hard work and dealing with angry wifes or girlfriends! We all appreciate it!

On mr2 it did feel like my battery was draining faster than normal.. with the stock kernel at least. Glad I'm not the only one try switching kernels
Sent from my Incredible using XDA Premium App

I actually had this problem too with the stock kernel, and once I overclocked with the Dream kernel it actually stopped draining my battery, strange.

I did try using Imoseyon's CM7 leankernel but had the same effect. Ill try the dream kernel and report back. Thank guys!!

I'm on my first day with this build of CM7, with MR2.5 and noticed my battery has drained way faster than it did with gingeritis.

Did you try wiping battery stats?
Sent from my ThunderBolt using XDA Premium App

Is there an official name for this kernel, or someplace to get it? I tried a quick Google search for "htc thunderbolt dream kernel", and it didn't bring up anything definite.
I noticed the battery drain too. CM7 7.1.0 RC1 with the MR2.5 radio. It seems to be "cell standby" that's using the highest percentage of the battery. I have it set to CDMA / EvDo auto.

What programs do you have running? Are you overclocked? I an running mr2.5 cm7.1 rc1.1 and still have 22% on 18 hours unplugged. 3 hour screen on, lots of texting, xda browsing, market updates, and an hour of plans vs zombies. On stock kernel, no overclocking. Using interactive governor.

I do have things set to run in the background, but they don't even register a high enough percentage in the battery usage to show there. I was not having battery issues with the 7.0.1 RC 6 on MR1 (the last build).

I've tried two of the utkanos kernels (not the OC one), and the dream kernel. On both of the utkanos kernels, I had no data. I tried rebooting several times, switching data on and off, and changing the network mode. No luck. The dream kernel took several minutes, but data finally came on. I haven't used it long enough to comment on any battery life differences between stock CM7 and this.

Running BAMF getting 1 1/2 on battery easy on 2.5
I am currently running the 2.5 on my BAMF sense 3 2.3.2 dream kernal. My battery is lasting very nicely currently. See the post below I have had better times the best was 1 day and 19 hours.

Ok so here's the news on my end. With the dream kernel things seem much better! However I was watching my ma usage and it went from 48ma to 240ma something after turning on wifi. Then after turning wifi off it never dropped. I rebooted and things went back to a cool 48ma. I'm guessing my original problem was with the stock kernel. But now that I'm on the new one the phone wont power down the wifi or something and made me burn thru my bat till I rebooted. Any ideas gents? Reboot did fix but that usually kills a good 4 to 10% of my bat everytime. I have next to nothing running in the background too.
Sent from my ThunderBolt using XDA App

Guess I should add that now after reboot I'm around 100 ma usage and steady with wifi on. Maybe a reboot once a day might do the trick till CM is finalized. Was thinking bout trying the mr2 radio stead of 2.5. Anyone know if there's a difference or advantage to either?

Battery draining after MR2 terrible

I have been running bamf 1.8.6 and the leaked mr2 for about a week and average battery life is a day I would say. Last night I flashed the official MR2 radio hosted here. Great signal. Gps didn't lock as fast as some said but still faster than before. I went to bed with 90% battery and woke up 6 hours later with 29% wth?
Sent from my ADR6400L using XDA App

i had about a 20% drop overnight, a bit more than usual but nothing too bad. ill test today after a full charge and calibration. i will say this update locks 4g fast and my signal is stronger.

my battery is sucking after official radio too. running CM7. gonna flash back to mr2 leak until the guys release an update hopefully with the new radio.

what update? the devs do not mod or create the radio's.

No issues here.. I feel like I have a real cell phone now.
Ive got about 14 hours of uptime right now with 45% battery left. I have mobile data always on, screen on auto-brightness, and gmail and weather syncing. Ive actually used the phone a bit also for surfing and a lot of texting.

the offical radio is the update. Mr2 leak is no longer supported or needed. It was canned by verizon. Radio version 1.39.00.0627 is the offical OTA MR2 radio

Here's what needs to be done:
1) Charge phone to 100%
2) Delete battery stats in CWM
3) Drain battery till phone shuts off
4) Charge to 100% again
5) Drain battery till phone shuts off
After step 5 you should be fully calibrated. Now if after doing this you still feel the battery is draining faster than before, then you can safely say you're seeing the adverse affects of flashing the official MR2.

Battery life after flashing a radio always sucks. You have to give it several days to adjust.

My Thunderbolt says, under Software information>Baseband version:
1.39.00.0627r, 0.01.69.0625r
Is having both those numbers normal, or should it just say 1.39.00.0627r?

The first one is the 3G radio and the second one is the LTE I believe. Might be vice versa but thats the reasoning behind having 2 basebands.

I also noticed that I won't switch up to LTE even when in a LTE area. If I put it in LTE only mode it will lock on immediatly and strong.

New radio = hot phone

Anyone else experiencing a hot backside of their tb on the new radio. Im even running battery saver mode, undervolted and no overclock.
Sent from my ADR6400L using Tapatalk

no but im not a fan of this new radio.

I agree the radio is great. Just im cooking eggs with my tb.
Sent from my ADR6400L using Tapatalk

i have been experiencing the same thing... big time !
regardless of what rom i use, sense/de-sense or aosp, the phone gets really hot after awhile. i've had a few instances where it got so hot that it froze the phone and i had to yank the battery and let it cool down.
for the hell of it, tried going back to an older radio and the problem went away.
damn.. did have a tad bit better battery on the new radio as well as a very slight improvement in reception... but considering the consequences of the new radio, it's better just to stick to an older one for now.

Was this only happening when using a 3G/4G connection or all the time? I haven't experienced that but I only switched to the new radio a few days ago and haven't done any long term mobile data usage with it yet. I do seem to pick up 4G at my work quicker and in places in the building where I couldn't before.

I know i read if you undervolt it too much it can cause a phone to run hot if done incorrectly. Causes phone to work harder since it needs more power.
Sent from my ADR6400L using XDA App

Refering to a couple of the posts above, i am in a 3G only area but i do heavy usage(web, movies) so the phone will be on for a few hours at a time.
As for "undervolting", i use DreamKernal + SetCPU and just overclock to like 1222. I also have a profile set so when the screen is off it is set to max out at 368.
Oh, and for the heck of it tried that VZW thing with pulling the battery to reset location and.it didnt help with the heat either.
On a positive note, at least if your hands are cold(or other body part), then hey!

i think the kernels have alot to do with the heat as well. i doubt the leaked 802 radio will harm anyone's phone. i will admit its a very wonky radio for me. ive just recently combined the cdma 627 radio and the lte 802 radio and all is well. i went 23hrs on a stock battery with lte on all the time. im running cm7+kangbang kernel.

I've been running the latest leak (2.11) rooted, along with the latest radios, for about a week now, and haven't noticed the back getting any hotter than it did before. I'll have to pay more attention and see.

How is the battery life of 4.0.4 Official AT&T version?

Can anyone comment on the battery life on the Official AT&T 4.0.4? Battery life is one of the most important necessity of mine. Right now I am on SKY ICS 4.2E with the nexus extended battery and I can go with a full charge from morning 8:00 a.m to 7:00 p.m with moderate usage. The ICS leaks were horrible, so that to back to stock GB. Tried Sky ICS 4.2F but 4.2E was smoother so went back and sticking to Sky ICS 4.2E.
If this official release is too bad on the battery life like the leaks, I am gonna skip and stay on Sky ICS 4.2E for a while.

If you're worried about battery life I would stick with SkyICS. You can wait a while till sean works on the ROM a little bit more but hes been working hard to get the tweaks with the latest ICS.

Check that frequently for more updates. :good:

two days on att ics, fully stock non-rooted... yada yada. day 1 was great got 11 hours with moderate to heavy use (mostly internet, set up, download apps). day 2 sucked, only got about 7 hours of use .... slight to moderate use (some internet, fb, 10 mins of map with gps).
i'm hoping day 2 was a fluke.

I'm impressed with it. I got a solid 12 hours of usage out of it. Playing tunes, texting frequently, downloading apps and what not... Keep in mind, I'm not on an LTE and as such I have it disabled. I've heard it can wreak havoc on battery life.
Can't give an accurate estimate for today, as it was plugged in and floating around 30-50%... But it seems better than GB to me.

What about your screen on time?

Yeah... battery life has been bad for me since I switched from skyics Rodgers edition to att official skyics release. Tried reflashing the rom a couple times but the problem remains. Just gotta wait around now for a solution.

The battery life of the official ICS was definitely better than 2.3, that being said I have moved on to SkyICS, and it's simply fantastic, even with the stock kernel

For me, it's excellent on wifi. On 4G, it's decent. I can go about 10 hours with moderate use and system power saving settings on.

Battery life
My wife and I have the same phone her's is white(stock) mine is black (rooted and using stock rom bloatware is frozen ). I am getting better hours of use with some Words with friends a few calls and a few txt message. I can go day and half before I charge. Wife has to charge nightly and she uses her phone less then I do. I am rooting her phone tonight after work. Both have upgraded to ICS.

My wife has my old Skyrocket now that I have the GSIII..She came from a Cappy to the iPhone to the Skyrocket and she swears by the battery life on her phone and she LIVES on her damn phone...(I do too, I'll admit). She claims it's even better with the firmware upgrade, stock & unrooted..

Stock rooted rogers, with heavy use, I've got a dismal 4-5 hours! But that's scree on & browsing... Good thing I'm close to a charger.......

12 hours! battery @ 78% didn't use the phone much since 5 am. Made a couple of phone calls, surfed play store... not much

i didnt like the battery life on the official build so i am using skyics 4.2f6 now with better battery life! Seanzscreams is the best developer for the skyrocket love his work.

for those of you who were like me and had horrible battery life on any of the ICS roms including Sky, i have found a solution i have tested this on 2 roms so far the first being my Daily Driver CM9 Nightlies, and stock ics. i found that for some reason when my phones screen turned off my phone would not go into sleep mode, the fix for me was to run SetCPU app, which i did pay for, and create 1 profile, for screen off, and just change the the cpu max and min speeds to max 540 and min, 192, i found that will keep your notifications coming without any lag, and when you wake the screen it will not be laggy as well. I'm Currently at 13 hours and my battery is at 79% and i played with the market, and surfed the web some, obviously texted a few time as well. https://play.google.com/store/apps/details?id=com.mhuang.overclocking&feature=search_result#?t=W251bGwsMSwyLDEsImNvbS5taHVhbmcub3ZlcmNsb2NraW5nIl0.

Pure bone stock phone here (for now), battery life has been pretty good IMO (compared to my Captivate). The other day I was down to ~72% after >15hrs of light use.
As always, YMMV. My theory is that it depends on the apps you have installed, and what version they are. I would get updates to some apps and my battery life would suddenly be different after the update (sometimes better, sometimes worse.)

My gfs on stock has dropped by about 50%. Lte in sf.
