So I know this subject has been hashed a thousand times. But... My tb was actually getting fantastic battery. Ten hours without charging. Right now I'm on the latest thundersense, no OC, conservative scaling, juice defender ultimate with data off when the screen's off, and my battery went from 100% to 49% in two hours. Am I doing something wrong, or did I just not quite understand that one day my phone turns on and says "I'm going to have terrible battery life from now on"? Because that's literally what happened. One day I was bragging about how fantastic my battery life is, the next was like I got blindsided by a mugger.

Charge it fully, calibrate the battery.
I will try that and post back if I have any issues.

Sorry for being a newb, but I keep on hearing about calibrating the battery in these forums. How do I do that?

Download Battery Calibration from the Market. It's free. Open the app, it notifies you when you're charged to 100%, hit the calibrate button and you're done. Simple as that.
I had the same problem and set a profile in setCPU to have max and min cpu speed at 245 while the screen is off. Used onDemand at 1.28 i believe and I went from charging by 4pm to still at 50% by midnight. It really was night and day.

One thing I'm having trouble with understanding is the governors. I'm using smartass right now with no profiles. Will it underclock the phone to 245 when the screen is off? I read an article that said it didn't need profiles so I assumed it did this automatically.
i never expected fantastic battery just equivalent to my Dinc which is 9 hrs, on average i get 8 with my TB so it works for me
I get quite good battery out of my Thunderbolt. I ran it on stock battery with light usage almost 60 hours before I needed to charge.

Thank you for the amazingly valuable contribution to the thread! We can all rest easy knowing that user 'boythatkills' has good battery life. Pack it up and close the thread, this guy gets good battery so therefore the OP is of no concern!

To op first I would ditch juice defender never been a fan of that app plus it also takes resources to enable data again seems counter productive somewhat. Second it does seem these phones have days where they suck down the juice. Also I would use ondemand instead of conservative I have never seen one person even back to my Droid that said they had amazing battery on conservative scaling. I notice way to much lag with conservative as we its only supposed to scale up to the clock speed needed but it takes to long to scale up in my opinion. I've always gotten decent battery life from Droid to thunderbolt and I've always used ondemand with the min clock speed when screen off. Also if you dont have spareparts get it from the market it may have been a rogue app for some reason that day. I have Google voice act up on me from time to time. Hope this helps. Oh and I'm getting 20 to 30 hours out of mine. Whoever said 60 hours must have it hooked up to a car battery haha.

I don't know about 60 hours on this phone yet. I have gotten 2 days with small usage, but not longer. This might be doable when CM7 starts getting nightly cranked out. Or when our AOSP kernels get better. That is when I started getting 3 days with my evo, but then again, that was with 3G only.
Ever since I did the battery calibration, it seems a lot better. I tend to flipflop back and forth between conservative and ondemand with my main profile- I wouldn't say conservative is a total waste, I'll reserve that for the powersave scaling. So in any case, was it just bad values were written to the batterystats.bin file? And if so, what steps can I take to keep it from happening again? Other than this little bump, I'd say the tb has been the best phone I've ever owned.

I have a friend that sent me this message today, which sounds like a great idea:
I've been messing with setcpu and trying out some underclocking profiles. Underclocking while the screen is off as well as reducing the CPU power has gotten me 75% battery left after 8 hours. This is with constant emails but no wireless, bluetooth, or gps. This is better than I was getting under windows mobile.
Using a complete black background as your desktop background screen also helps with battery life. The black areas dont use battery power.
If you install one of the cpu meters, it will show that there is automatic underclocking... mine says it has been running at 100MHz for 76% of the time (1 day uptime).
Android System Info will tell you this.
Now, I'm not sure if this is the same as what you are doing though.
You know, I believe that is correct. I don't know if he is getting any advantage or not. I'll forward the info to him and see what he thinks.

That only helps if you spend a significant amount of time on your phone's home screen or hit buttons a lot when the phone is in your pocket.
I've found that the best way to save battery life is to use manual brightness. Auto brightness is just too bright. In fact some newer firmware hidden on samsung's site does make auto brightness a bit dimmer.
Using manual brightness I get about one hour and fifteen minutes of screen time per 10% of battery. I get about an hour per ten percent at work, where it's brighter. I get about half that with auto-brightness.
I think one good way to test which i am going to do to tonight is charge your phone and right before you go to bed unplug it and let it run through the night and in the morning see what sucks the most battery. i'm going to assume it should be "phone idle" but if its cell standby then something is sucking data, someone correct me if im wrong .
Just flash to jh2 out jh3. I'm on 16 hours and have 50% left

I know my 8525 (a precursor to the tilt) had excellent reception. It was far better than average. This captivate is not as good. In my experience the captivate has average reception. I've had much worse.
Well, my buddy that told me about the topic I used to start this thread just stopped by.
He is playing with an Android 2.2 ROM that has been installed on his HTC HD2, which also is undervolted a bit. And of course, tweaking with SETCPU>
He said he is getting email and messages etc as normal; has full CPU and good power when using it (BTW...the Quadrant readings on his phone is coming in at over 1700). His phone has been up for 24 hours, 15 minutes when he stopped in, and he had 58% battery left. Before he started tweaking (and I think before the undervolted ROM), he was getting 11-12 hours on a charge.
Sounds pretty good to me.
okay well i am one TB owner who suffers greatly from poor battery life. so bad i have 4 replacement batteries and one extended! i try to cut back on my usage to help this but its so hard, especially at work where i carry 3 spare batteries with me. now at first, Juice Defender didnt work but it recently got an update that made it work with the Tb and it works great. i used to get 6 hours top on a battery. now im getting 13+ hours with 6+ hours of awake time (i was asleep during most of the other hours). i am overclocked at 1.4MHz, running the latest BAMF rom and kernel. i have SetCPU set on conservative. Gmail pushing automatically with everything else updating every hour. Twitdroyd updating every 5 minutes and a lot of texting, games, and some music/Slacker Radio throughout the day. i think this is GREAT for me, seeing how im not used to getting this kind of time. i cant wait to test this with my extended battery to see what i get! how about you guys? have any of you guys been testing out JuiceDefender? might get some of you whiners to stop whining haha jk what are you experiences with the TB and JuiceDefender?
PS, on a side note, i never really messed with SetCPU like that but which "profile" (i guess u can call it) gives the best battery life with out sacrificing a lot of speed? i know theres smartass, ondemand, conservative, powersaver but which is best? im just curious since i never touched this
The reason JD is saving you so much battery is you have a bunch of stuff syncing. And JD is preventing it from syncing. (Twitdroyd in particular)
All JD does is turn off your data (wifi/4G) radios when the display is off. I've measured it and for me, 4G/wifi idle only pull 1/4 of a percent every hour. So in a 24 hour period I've only lost 6-8 percent from idle data.
What's your display on time?
I normally use on demand for setcpu since smartass can have issues if not coded perfectly ( I also like the control of on demand) and conservative can cause lags when there are cpu spikes.
When JD wasn't working, I started using Green Power, which has been working fine for me. Any reasons why some people think JD might be better?
BTW, one thing that seems to have helped me is to use 4G-only mode at work where I have a very strong 4G signal.
I only have one spare 1400 mAh battery and one 2750 mAh battery.

Only 8 percent? I lost over 30% within a 8 hour period with 4g on. And 11% with 4g off when idle. I have background sync off, set CPU clocked at 245 MHz when the screen is off.
Maybe I should exchange my TB?

Me? I'm in the range of 2 - 3 bars at home on 4g (mostly 2). When I'm out I get 4 bars.
I was always curious how the BatteryStats.bin works when using multiple batteries... especially if you are using a combo of standard and extended.
Does the device get confused and need recalibration? I am not sure if it would be reporting the correct battery stats to the device and may require calibration... but I honestly do not know.

Bars don't mean anything, you can have no bars and still have a full 4g/3g/1x signal. The signal db level is what matters, not bars.
My guess is that the optimizations from BAMF and the undervolted kernel combined with the smartass governor through setCPU are dramatically helping you.
There's no way that juice defender doubled your battery life with stock kernel and ROM.

That percentage is souly from the radio, not including al the other processes. I do get super good 4g signal so that probably helps my battery life
Im rooted with setcpu set to drop down to 245/368 when screen off and have Juice Defender with UJ, unplugged at 100% this morning at 7:30, its 2 now and have 88% left, texted some and had a 10 minute call over blue tooth. Stock battery.

Oh okay. I misunderstood
I wouldn't usually start a thread but i feel like this is worth getting out to the public.
I was sick of the battery life on the tb but i can say i have found the cure.
I went all out and tried all the goods and i found out how to make the battery last at least twice as long and thats being kind.
Just to let you know im no developer but i do understand the just of it.
Ok so this is it. (this is for rooted phones)
Step one. Download setcpu (i think this is the most important thing to save battery life)
Step two. open setcpu and navigate to profiles. This is where most of your battery is saved. (I Think)
add profile. It is pretty simple just tell the phone what to do in certain circumstances.
This is my set up and i will tell you it works.
battery 35% = 844800 and min
charging = 998400 and min
temp = 54.7 c 844800 and min
AND THE MOST IMPORTANT
SCREEN OFF = 384000 AND MIN
This is because i dont care how fast my phone is when the screen is off.
Step three. Some people dont believe this helps but hear me out.
download Advanced Task Killer.
I does not matter to kill apps by clicking kill apps cause they just start back up but if you set it up to kill all unwanted apps when you turn the screen off then the apps dont open back up till you turn the screen on again. (this will let the phone sleep quietly when the screen is black.)
Step four. This is for the little things. Just go through settings page by page and turn off what you dont need. For example i dont care if my phone vibrates when i type, i actually like it more with out it. And i recommend turning off animations, if not just to try it cause i really dont notice them gone.
Step five and the finale one. I have tried the phone on 3g and 4g and didnt seem make enough of a difference to make me happy but for this test i was on 3g although i am on 4g now and am very happy with how the battery is performing.
I hope this helps and if you have any questions dont hesitate to ask.
Im on an extended battery and did all those things you mentioned, but still saw massive battery drain and I get about 6-8 hours before having to charge. I then started turning off 3g when I dont need data. The phone still works with 3g off and I can still text and recieve emails. When I started doing this, my battery life was incredible. Im getting over 20 hours now and sometimes a day and a half between recharges. I just flip 3g on when I need to surf the web. Im on VirusRom and ziggy kernal.
Flash a kernel. Setcpu. Better battery life without having to sacrifice features. Accounts and sync make sure everything you want syncing is done properly. Change brightness to a set value. Do not use auto brightness. I would have to disagree on task killer, task killer is an app that is constantly running in the background. Why have an app that kills apps (improperly) when android does it automatically native. Just my two cents.
The main battery drain is the 4g and HTC knows and has stated its an issue. The latest ruu was the first step at fixing this. As tasted before we are te first ones to use a new technology we are basically guinea pigs.
On the EVO you only turned 4g on when your phone knew 4g was available which is a good reason why there weren't a massive amount of people moaning about that phones battery. As I'm sure everyone knows the thunderbolt is always actively scanning 4g and may also have some 4g data leak issues (as I'm sure some people have noticed with some high data usage when not doing a lot). I use 3g (4g is not available in my area) and easily get a full day 16+ hours of battery usage as a norm.

Honestly, that's still fairly wasteful if you want to save battery. Little performance was sacrificed in my setup.
Screen off: MIN, Conservative
Temp > 45 C , MIN, Conservative (I don't want anything to melt in there)
Battery < 80 %, .8 GHz, Conservative
Battery < 35 %, .4 GHz, Conservative
Battery < 15 %, MIN, Powersaver
My point is that at .6 GHz with Conservative governor, Sense was still snappy, fruitninja has as almost zero lag, etc.
Feel free to experiment with SetCPU! It won't blow up your phone. (Probably?)

See, this is funny. What do you qualify as "great" battery"? You are getting "great" battery for a phone with incredibly horrible stock battery life.
So by all means, dont speak for the community. Its known Nation Wide.. even when speaking with Verizon employees, that the battery sucks. They are even sending people extended batteries for free or with a huge discount. Yet you come here saying you have the Jesus of all battery settings when you probably hardly use it.

I don't have amazing battery life I have great. With screen on 2 or 3 hours I can get 16+ hours of battery life on 3g only. Others say the same thing.
Talking to Verizon employees is the just dumb. They know how to activate phones that's pretty much it. How many sim cards were ruined on launch day from Verizon employees.
Finally you can check my post history I am on my phone (mainly xda) almost constantly every day. I email, text, call, play games, etc.. you got a problem with the battery switch to Apple. They will hold your hand to great battery life.

Works for me.
I keep a spare battery in a small SanDisk zippered pouch, in my pocket.
My phone is never on the charger, ever. The batteries get swapped when needed and the empty battery goes on the charger.
I don’t have 4G in my area and know even if I did I would leave it turned off. Not sure what everyone is doing on their phones that need a lot of data speed but whatever it is I am not. 3G is fast enough and I would much rather have the battery life. With the 4G turned off the battery life is shockingly good.
I guess if I was doing wireless tethering or something I would want more speed but for using facebook, foursquare, Kindle, Gmail, Skype, News and sports new... I don’t really see why I need a faster speed. Browsing the internet is fast enough but I admit I don’t do a lot of that anyway. Almost everything I do is app based not browser based. Seems 4G would be most useful as a hot spot speed and not really needed right now as an actual phone data speed. IMO.
I woke up this morning at 5am an found that my Thunderbolt was running very hot. 60 degrees Celsius to be exact and the phones charging led was flashing from amber to green very quickly. I pulled the phone off its stock charger and pulled the battery to find that the battery its self was very hot and even producing and odd smell. I let the phone cool for five mins an once cold to the touch, I installed my spare battery and with heavy use, I am back to running temp of 34c and not sure what caused this??? Phone is rooted an running Bamf 1.6.2 overclocked to 1.4 and has been running like this since may 5th with no issues. I have noticed in the past two days, so very rapid battery drain but haven't installed anything new and i have all HTC sense apps not syncing... Any ideas?

Do you use SetCPU to overclock? I would recommend it, as I think it would've prevented your phone from overheating.
I have 3 profiles set up, and then have the overall max set to 1.4ghz and min set to 245mhz using Smartass. I've found it's always a good idea to have a profile set up to limit the overclocking when the temperature is >50C, to prevent damage to the CPU. I have a profile to limit the max OC when the phone is charging, to help prevent it from overheating. I also use a profile to limit the max when the screen is off, since you don't need the extra speed then, and it helps on battery life. My profiles are:
Temp > 50C - Max=768; Min=245
Screen Off - Max=368; Min=245
Charging - Max=1024; Min=245
Just set up all these profiles and even added another. Thanks for the tip! I hope this helps with battery life also.

Are any of the governors better than the others for handling this?
The goverer used really depends on your own personal usage of the phone. Experment and see which works best for you. FWIW I use interactive and am pretty happy with it.
Ill try that one out. I found Ondemand to waste too much battery, and smartass to be passable.
i just had something weird happen myself. i just installed NONS3NS3 rom and then 'adownloader'. had it downloading a file then all of a sudden the phone locked up and was completely unresponsive. i pulled the battery and it was incredibly hot. waited for it to cool down and now everything is normal again. bizarre, because i could use adownloader just fine when i was on CM7.
My phone gets warm to when i charge it but not 60c. The kernel can cause this too.

I don't think the battery has any issue. When a Li-on battery fails, it will create a lot of heat, but it will also alter the resistance and voltage characteristics in ways the phone will detect.
If SetCPU resolved the issue, then you've got an issue with your ROM. It shouldn't do that under normal circumstances, and even if you're using SetCPU, something is still trying to use resources abusively. I'd try a different ROM or radio and get SetCPU off of there. It's actually abusive in itself with resources. It's great for testing OC settings, but for long term implementations of settings, a script is the ideal tool for the job as it implements setting directly to the kernel with no further intervention.
First and foremost, I completely understand the battery reporting is inaccurate.
I, like most of the G2x users, have occasionally experienced excellent battery life and at other times barely lasted 5 hours. We all know this has to do with the LG battery drivers. I think I may have found a potential stop-gap fix though.
Another preface:I'm running CM7 nightlies.
Now, using SET CPU you can set a screen off profile that will underclock the cpu to be more efficient and save battery life, anyone worth their salt knows that. The other aspect of this that I have been doing is underclocking the CPU during normal usage. With min set at 312 and max at 760, I've gone 4 hrs and 13 minutes with 96% left. Even underclocked, this phone performs. The only issue I've noticed is a little bit of buggery with the lockscreen reactivating but honestly it's worth it to me to have a phone that lasts.
The issue is with the battery drivers, nothing else, your "fix" are just ways to increase battery life
