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.
Hey guys... I finally updated my E3D with that update. My sister and dad both updated theirs when they first got it.
I'm getting really good battery life. Minimal usage yesterday, but after 16+ hours I still had more than 60%... I even played a little N64oid.
However, my sister and my dad both get pretty bad - decent battery life. My dad doesn't use the phone nearly as much as me.
I wish I knew what settings are doing it. We all have the same settings but my idle time loses me like 2-3%/hr but for them it can be up to 7-10%/hr.
Anyone in a household with more than a couple E3D's getting this varied battery life?
Settings are virtually the same, and location isn't a big factor either.
A lot of things impact battery. If the settings are the same across all phones perhaps the drain is app related. If you really want to test you should factory reset all phones and then check. This way all truly have same settings and apps. I would bet at that point they all drain the same.
I did the OTA and my battery life shot up instantly.
Before the OTA I would have around 15 hours of light to moderate use of text, calls, and browsing before it hit 50 percent. Now, I would basically do the same things but I can go a full day before it hits 70 percent.
I bet you they use the phone more...calls..facebook....etc..friend of mine gets couple hours...and he plays games non stop.
Anybody else notice that standby battery life seems to have gotten worse in 8.8.3.33? Mine was dropping less than .5% per hour before, now it seems to be considerably more (just noticed so no chance yet to quantify)...
Edit: Actually, I'm leaning toward battery life in general being worse...

Hard to say but I'm leaning towards maybe lol
I agree it could be a maybe.
Mine was fully charged when I disconnected it before work. It's been sitting at home on standby for 15.5 hours and it's at 94%.
During that time it's been connected to my WIFI, it updated google translate, and it synced with 3 e-mail accounts every 4 hours and my main email account every hour.
Seems the same to me.
mines seem to get even better battery life after update. check your background processes to make sure they aren't any unwanted background apps running. those will drain battery. overall battery life is great and the standby life is unreal how good it is. do you think your battery fully broken in yet? how long you had it?
Mine seems worse as well. No testing to prove it but it's been in the back of my mind since shortly after the update.

Nothing new since the update as far as background processes. I've had it since Friday, and it's had two full charge/discharge cycles. But again this is compared to before the update...
I'll let it sit overnight and see if this is just my imagination.

Mine goes down 15% per hour - mainly browsing www. isnt it to much? Before and after uptdate
i had 99% a hour ago and now its 90% i have only watched 10minutes of iplayer and read one email the rest of the time the tablet has been on stand by. i have a task killer running and it was up dated yesterday.
also i cant seem to see Time remaining of the battery rather than just %
its as bad as my HTC HD before it was rooted
As an update, I let it sit overnight for 8 hours and it went from 15% to 12%, or about .375%/hour. So, that's pretty good standby performance and my impression was mistaken.
After using it, though, I'm thinking my impression was coming more from battery life in use, which does seem less than before. I think they've done something with the power settings that I'd expect them to undo in the next update (or just in the ICS upgrade).
The power mode you using, type of activities you doing on prime, and brightness will directly affect battery drain while device being used. I always have my prime in balanced mode for the best of both worlds, Performance and battery life. as i never had any lag or any anything in this mode. I've noticed, even with heavy usage in balanced mode, battery drains about 10% or a lil less per hour. if light usage then it even drains less. Check out my "Different Performance Modes of Prime/Tegra3" thread. I started it to address issues like this and people compare performance and battery life in different modes. as everyone will have a different setup or use different. There is also a bstterylife thread started by TylerZ that needs resurrecting also. now that all the preorder threads n such got merged we can have some more relevant threads stay current.
honestly though, the battery life is amazing on this tab. to the other guy saying he has a task killer rubbing in the background..lmao that's his problem right there. Honeycomb or ICS doesn't need task killers as memory managemanent is already taken care of by the OS itself. and does a pretty damn good job at it also. if you wanna kill one or 2 apps that's OK. but to have a task killer running in background of honey comb OS does more harm than good.

i've noticed a slight downgrade in battery life while using the tablet, but not in standby mode.
also noticed that changing the performance mode no longer seems to make as big of an adjustment to the screen as it used to. perhaps the update increased processor performance, which explains why it feels snappier in general, and also seems to use up slightly more power.
By inherently bad, I mean are there some extra power sucking hardware components that were just poor design choices (processor/screen) and therefore can't be remedied through software fixes?
I understand that the sensation has decent battery life, whereas the amaze does not. Yet the Amaze should have a more recent processor and a larger battery. So I just want to make sure before I buy that if I'm willing to add a custom rom and use juice defender this will make the Amaze no more power hungry than its direct competitors.
Thanks
I'm thinking most of the drain is coming from the extra work caused by Sense. Custom ROMs do help with battery since they are debloated and all but when we have something AOSP, battery life should be much better. I had experience with my old Moto Cliq where Motoblur would just chug battery. It wasn't until we got AOSP or CyanogenMod that the battery life was acceptable. You could also buy an extended battery like Anker. With the ICS leak, I heard some people report better battery due to better management with the dual-core CPU.
To summarize, we can extend battery life greatly. I'm not sure if there are any hardware stuff that causes shorter battery life though.

It's only bad if your going to play one of the new console quality games out there or anything else that really going to push that dual core 1.5mhz chipset. Imagine powering your laptop with a battery the size of the one in your phone that's what you get. Get a car charger grab a Pocket seized power pack from Amazon for $10th or an extra batt and you'll be fine. Either that or just text make some calls & listen to some music and let all that power chill & you'll make it all day no problem. Push it hard & it's dead in 2hrs. But the things it can do are crazy. This thing has more balls than my laptop. Just my 2 cents.
I don't believe that the Amaze's battery is inherently bad. I was able to get 10 hours off of Beast Rom with moderate usage.
I talk a lot on Skype with my relatives sometimes. It's much cheaper for me because I'm using the T-mobile 5 gigs of 4G at $30. Lots of data but only 100 minutes.
So I'm pretty familiar with the battery life. With the new ICS leak my battery life has improved a lot. Still had a green bar on the battery even after using Skype on 4G for over an hour. I do however keep a charger at home, car and at work.

On stock yeah the battery life is HORRIBLE, I am a average user and it use to last me 6-8 hours and sometimes less. After switching to Energy rom my battery improved GREATLY, I had anywhere between 12 to 16 hours.
With the new ICS leak that came, I notice stock had improved significantly over previous GB stock ! I just switched over to Revolution, checking it out to see how it is although I much prefer the Energy rom simply because of the 5x5 layout.

Wow, thank you for the reassurance. I was getting 6-8 hours as well. I am highly skeptical that a ROM could make that much of a difference, (going from 12-16) but I am happy to try.
I have noticed on some days prior to the pics leak that I would get 10+ hours and some cays I would get maybe 5 Max. Bone stock btw. Since the update I am killing that thing. I was able to go 6 and that was with the radio off, no sync, nothing. Only thing running was a podcast. Then again for the first time I was able to get 12hrs via radio off. I don't know I am personally not too happy with the radio update. Regardless I am glad I have the leak and I'm glad there is a place like this where I am giving so many options and get to learn more about this phone.
Thank you xda members glad you are here
i get great battery everyday. since day one by far the best phone i've owned in every aspect but the battery life for me is incredible.

You don't have to be a farmer to know what sh*t smells like.
Well... here's my results
Stock GB Amaze: After 10 hours (with moderate use) I was at 20%
Unlocked bootloader.. installed NRG's GB ROM (still waiting a bit to upgrade to ICS.. mainly waiting for radio issues to be resolved)
Before I had to plug in for the night, I was at 13hrs54minutes with 30% battery left and MUCH MUCH MORE awake/screen time (total screen ON time was at about 3hrs45minutes) than the test with stock..
So yeah, the ROM you're running makes a GIGANTIC DIFFERENCE.
Does the energy gingerbread and the energy ice cream sandwich rom get the same battery life? Have the ICS Roms been maximized for battery life like the gingerbread Roms have?
What has been people's experience with battery life with the different ROMs? I've been on AOKP for awhile, and the battery, quite frankly, sucked compared to stock. I'm currently on PA and am getting just under stock. For me, battery life is first priority, even if there is occasional stutter. Testing battery life takes a long time, so I just wanted to see what others have been seeing. I would stay on stock, but I really want Tablet UI and real setting toggles.

Disable Google Now and see if that helps, totally did on my HOX and I've yet done it to my Nexus but I've not used it enough to actually deplete a battery yet.

You sort of want your cake and eat it too. If you want a ROM full of features and packed full of unicorn blood and the tears of leprechauns something is going to have to give and that will always be the battery life.

I read a lot.
Don't game.
Watch videos with zero stutter.
I finally charged my tablet last night. Im at 82% in 8 hours.

I'm addicted to my tablet... I've been using it without stop for the last three hours. This are my results with Paranoidandroid:
Very similar with stock though. I think I could upload some as well.
I'm pretty sure this is stock. Not a lot of difference as I said. Both of the images are with very heavy usage, I mean, screen on all the time, but almost the lowest brightness. With the screen off I get almost no drop.
(I couldn't attach the image in the previous post)
Battery life will always be a combination of idle drain + screen on drain. THe most important is obviously how long you can actually use the tablet (screen on time), but you also need good enough idle drain to not lose hardly any charge between when you use your tablet.
The more features you add the less battery life usually is. So either keep PA so you have the tablet UI or use a ROM that is very close to stock, like the stock ROM from scrosler or Muzzy's ROM.
A kernel can also have greater effect on battery life. If you want the best battery then go with KTManta kernel. Use either PegasusQ or ktoonservative governor and add in some undervolting to lower power draw. Using this combination I was able to get over 13 hours of screen on time in 1 charge. Idle drain was about 1% every 8-9 hours.
Personally, I've found that my battery life has improved maybe 10% since running cyanogenmod. If I'm really lucky I can get 7 hours SOT. Not a huge improvement over stock, but its definitely better.
Its worth noting that I use the "performance" CPU governor, which is supposed to be a battery killer. Strangely it doesn't seem to make much difference for me though, it just makes everything quicker!

Well, it is difficult to notice a higher battery drop when it is already insane... XD. Well, according to battery widget I'm getting around 8h with the screen on, which is not bad.

I've used the "battery widget" for a very long time and that app is a battery drainer. Got way better battery life uninstalling that app.
