[Q] When to Battery Calibrate

Do i need to do a battery calibration when switching between the extended battery and the regular? Depending on my work day i take a different batter with me but the extended seems to be dropping as fast at the standard one. I am running Blurry 1.3 ROM.

IMO its just a placebo effect

I had never run one before but when I stitched to blurry 1.3 I was losing 10% battery life every thirty minutes while not in use!! I was told to run the calibration on it and boy did it help, now I drop ten or so every hour/hour and a half with heavy usage, and only a percent or two when not in use.

Absolutely. Placebo? The battery stats are for the stock battery. You put a bigger battery in, and you don't think you need to tell your system?
Don't calibrate and enjoy the same battery life you got on the regular battery.

I'll post a link to a great calibration trick in a minute. I was easily getting a day and a half on my x2, with heavy use.

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.?
Sent from my DROID BIONIC using xda premium

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.

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.

[Q] New cpu app to help with battery life?

Found this new CPU app and you can change the voltage in it
https://market.android.com/details?...29tLnNtYXJ0cHJvamVjdHMuQ1BVQ29udHJvbExpdGUiXQ..
I was wondering if blitz supported the voltage adjustments as maybe it would help us that get a decrease in battery life because of blitz? Ik its UC already but thought fine tuning it to phone could help even more?
Also, if you were to use this with rom toolbox would the CPU settings interfere? Would you have to remove rom toolbox?

Can't change voltage. Lol

Okay thanks I'll try it out.

A few things that people seem to forget when comparing battery life. One person can get twice the battery life than someone else for many reasons.
A few:
1) are you in a 3g or 4g area? 4g will use more battery because of dual radio (recommend to switch to CDMA only mode when in a 3g only area, OR when you don't need 4g connectivity)
2) What options are running? (Wifi, GPS, Bluetooth, etc) Don't have any of those features on, especially Wifi, it will suck your battery down quick.
3) Your CPU app (Such as SetCPU). Is is set to Performance, OnDemand, PowerSave? I don't fiddle around with custom settings, just use the stock of those 3 and notice a major battery improvement with just the stock PowerSave.
4) Is your screen brightness on manual or auto mode? Auto mode will take 2-5 times as much juice as it's constantly scanning and changing screen brightness.
5) (almost forgot this) Most importantly, make sure you are in a good signal area (at least 80%) before complaining of poor battery life. Anything below 80% signal can cause your phone to search hi and low for a better tower and better signal. Anything below 50% is likely to draing your battery in half the time, or even less. Constant scanning for a better signal uses up a LOT of juice. I've had past phones that lasted for 2.5 days on a single charge when in full signal. Down to about 10-12 hours in poor signal and similar usage in both areas.
5.5) Those who don't yet know... Don't complain like the ones on Verizon website/reviews where the only thing that some will complain, or markdown on, is battery life. You are using (by assumption you reading this in this forum) a 4g, dual mode phone. NOOBS: This means there are two radios/antennas in your phone that are working together. One on 3g(CDMA) and one on 4g(LTE). This automatically makes your 4g phone use more battery. Don't like it? Go buy a 3g only phone... :O
Make sure to also not have any 'task manager/killer' running. These apps are not only bad for your phone (been proven), but they also use more juice than they save. At least in my experience and from other posts I have read.

Copying battery stats file?

Would it work to just copy the battery stats file to another rom so u don't have to re calibrate everytime u install one or would that be a bad idea

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%

Two hours of screen on time contributed to only 10% battery loss???
Did you just left it with screen on without touching it?
