Which rom has the best battery life?

Currently I am running Liberty test build 48. It seems to last me around 6-8 hours on light use but I can't live like this forever. Light use is not why i bought this phone Lets face it. With heavy use every rom I have used has been around 35% after around 2-4 hours of heavy use with 4g enabled. All the reviews gave the bionic great battery life reports. But this is poor, I live with a charger in my pocket.
So my question is which rom are you using and what are you battery life experiences.?

Stock. Debloated.
Battery life? More than 6 hours.

Keeping 4g enabled all the time is what's killing your battery. All of the 4g phones have the issue but from what I've read Bionic is the only one out with decent life.

I have never turned 4G off on my thunderbolt or bionic.
My bionic stock got about 20-30 hours with moderate use. With the TH3ORY roms I get about 8-10 hours.
The Thunderbolt got 6-8 hours stock, and 10-12 on the bamf roms

20-30 hours!? I'm in awe. I must be holding it wrong or something lol.
I got 6-10 with 4g enabled but didn't answer the phone lol. No usage.

And yeah, 20-30 hours man? Was your phone dormant? Sleep mode perhaps? Did you lose it? Was it turned off?

Dumb question...but are you calibrating your battery every time you flash a new rom? If not that is your issue.

No task killers, LTE enabled but on wifi most the day. Normal use. I got 20-30 hours on stock. Do your research I'm not the only one.
Coming from the thunderbolt I was very impressed.

I do restart my phone every morning and keep the text and things cleaned out.
Just like a computer the better the maintenance the better the performance.
Also as I understand it don't run task killers, its like pulling the plug on your computer over and over and then wondering why everything is unstable.
Also isn't gingerbread built to close apps if they aren't in use after a set amount of time?

6-8 hours isn't good
I've used most Android based phones and all of the Iphones. Loved the utility of the Androids but loved the battery life of the iphones. UNTIL the Bionic.
Based on my Thunderbolt experience I opted for the extended battery for the Bionic. Don't really need it. I use my phone almost totally for data and GPS. Easily 10 hours of heavy usage on standard battery. Not sure about the extended battery.
If you are only getting 6-9 hours on regular usage you really need to trim your running apps or return the phone. In my experience that is WAY under what your expectations should be. My best guess would be about 12-15 hours.

I should be getting mine in the next couple days and I've been curious about the use of 4G.
Is there any reason to have it on for the typical phone features? Such as phone calls, texting and idle. Unless you're a really heavy data user, it seems like you could have 4G off for a fairly significant portion of the day. Am I overestimating the power saved from having 4G off?
I haven't decided whether or not I plan on using any of the current roms, but I'm definitely not going to use one if that's the kind of battery life I can expect. I'd definitely like to hear more input about battery life from those using roms.

I have the 2760mah extended battery. Running d3blurr3d beta4. Im currently testing my battery to see how long it lasts. Right now im at 24 hours and I have 37% battery left. Battery life has been insane coming from the tbolt. Im in the moderate to heavy use bracket.

D3blurr3d or r3blurr3d?
Sent from my DROID BIONIC

Well...
Having tried all the custom roms out there I can say without a doubt that d3blurr3d (currently running beta4 but beta6 is current) has the best battery life. I agree the r3blurr3d ate my battery alive but this d3blurr3d is a whole new story. Off battery with moderate usage for 12 hours I sit at 53% right now with the extended battery...used to be below 10.

How does it compare to your stock experience?

Where is reblurred at? Saw it before but nit recently. Lately just r3blurr3d 1.7 or the liberty teat build on andirc#bionic
Edit: nevermind found it in deblurred on page 50 in rootzwiki forum
Sent from my DROID BIONIC using xda premium

Stock debloated, 10 to 15 hours if I'm in a good coverage area, if the phone is looking for a signal 2 to 4 hours.

Vivid Battery Life

So those that have a Vivid how has the battery life been? HTC has been getting a bad wrap for that.

RE: Battery Vivid Life
Mine has been absolutely horrid. With moderate use I'm lucky if it lasts 3 hours. To be honest, though, I didn't let it charge completely when I first got it - I was too excited. I'm actually recalibrating it now in hopes of improving it.

The notification light blinks yellow, and a big battery image and a message pop up on the screen when the battery level hits 10%, then again at 5%. It's pretty obvious. Also, the phone shuts down some background functions such as data syncing to conserve battery power.

Full on data streaming of my podcast or Rdio on Hspa drains my battery in 5 hours or so. With sporadic web browsing in there, just listening to cached music and podcast I stretch it past 8 hours. Better then my desire by 2/3 hours

Yeah, I thought my GS2 was good, but this is definitely better, especially considering LTE.
I finally ran it down to low battery the other day because an app ran away with my processor and drained my battery in the background. It did this in my locker while I was at the gym. When I finally pulled it out of my pants, it was super hot and down 20% lower than usual for that time of day. I restarted the phone and still managed to make it through the rest of the day and night before it died, but just barely.
Runaway apps is one of the things I have always hated about android, but that was the only time it happened since I bought the phone, so I can live with it.

Yeah, I'd read reviews that the battery life wasn't spectacular - but this is downright confusing! Do you think I ruined it by just using right out of the box without letting it do a few charge cycles (again I was TOO excited, the most excited I'd ever been about a phone)?

Is My Battery Defective?

Just wanted to see what you guys thought. I have the official extended battery (albeit purchased from Ebay). I’ve had my Bionic for about 8 weeks now and my battery life has started getting progressively worst. I checked for any rogue apps eating away battery life and all seems to be well. On average it’s lasting about 6 hours with moderate use. Here’s the breakdown:
Cell Standby: 43%
Phone Idle: 40%
WiFi: 8%
Display: 5%
Bluetooth: 5%
Voice calls: 3%
4h 53m 47s on battery with 20% remaining.
My phone is completely stock, not rooted. It’s also been running a bit hot lately, right now with no use it’s running @ 39c/102f. It also takes about 3 hours to completely charge on the stock battery.
According to the system my battery health is good as well. Any ideas? I can’t find the stock battery so I would have to purchase another one to compare.

I like to use the Watchdog app to see if there are any apps eating up my battery. Maybe it'll help you. https://market.android.com/details?id=com.zomut.watchdoglite

I remember an issue where your phone just scans and scans the sd card. You'll need to save everything to your comp. Format. Then put it all back. Should be good then.

Watchdog just helped me isolate the problem. It does include a task killer though.

This happened to me as well. Shortly after getting the extended battery my battery life was worse than the standard battery. Mainly cell standby eating battery under usage stats. This was mis-leading. I used an app called System Panel to isolate the issue to the external sd card, which led me to a corrupt movie file. Deleted the file and reloaded movie. Have had excellent battery life since then :^)

can you format the sd card straight from the phone, does it matter? I've also had worse battery life since popping in my micro sd so i unmounted it for now

Yes under settings/storage/unmount sd card then click format. I actually formatted my internal memory and sd card last night. Battery life has gotten much better since then.

You don't need to calibrate, just charge it full. Battery stats are automatically wiped when you unplug with a full charge.

It shouldn't affect battery. I've tested it myself, battery life before and after calibration is no different. This calibration myth was debunked by a google framework engineer.
Sent from my XT860 using xda premium

ya I read a short thing on that. Kinda odd though. Seems like sometimes u could get a worse battery life some days compared to others. But it also seems like a good idea since u don't have to calibrate every time u do something.

The calibration has nothing to do with the battery life, it just gives a more "exact" reading of the battery level.. I miscalibrated my battery once, and it was at 1% for about 3 hours, then finally died..

I have now been convinced that there is no reason to calibrate your battery at anytime. Google engineer pretty much put it to rest and since then I have flashed repeatedly and all that changes is the ROM , sometimes battery is bad and other times its great. CM9 is best so far. Until we get new kernals our battery won't ever be great.

Ya reading through the comments it seems batterystats.bin has nothing to do with the displayed battery level, but rather just what is using the battery. The displayed battery level comes from kernel level

Same, although not for 3 hours but 15min heavy load (720p mkv). Which normally kills 10% battery.
After calibrate it never happened again and died right after 1%
