So my battery has been great since switching to bangster's build. I loved it. Only thing that confuses me was my "about battery usage" status. It shows that my display is eating the majority of my battery. Any idea?
I'm using the latest tmousa radio. My setting is always 25% dim and no animation. I don't have live wall paper nor any widget that requires constant update.
I've attached a screenshot to show my status.

How did you get that screen? Then I can compare. I'm sure it's correct and probably normal if you think about how big it is. All those numbers are relative to each other. Your screen is going to take up the majority of your battery compared to apps, regardless of what it's set at. I bet if you set it at 100% brightness, the percentage will stay about the same.
Mine has always had similar readings regardless of build
i also got 80% ? even when i turning off the brightness :-D
Mines doesn't ever seem to take as my much but my android system does.

Wow my screens sucked sorry lol
but after about 50 mins my display was 16% and my system 60%

80 percent is pretty high.
These are my stats after being off the charger for about 8 hours. Even if I had my screen on and playing on my phone all day I have never seen dispaly that high on mine.
Maybe the app you're using isn't working correctly on the HD2 (what is that, taskkiller x?)
As long as it's a minor inconvenience like that I wouldn't worry about it...
I was running dark stone's build before this and I remember system taking the majority of the load so I was just concern about my display setting.
I have task killer but not set to autokill. I'm stumped on this. Maybe it is normal since my battery life is better than ever.
Maybe I should post this question in bangster's thread to see if other users of this build experience similar things.

Yea i used some free one called screenshot, looks fine on my phone not when I uploaded it. I feel my battery is pretty good coming from a Sprint touch diamond whose battery is horrible and being that I use WiFi a lot.

The screen using an average of 80% of the battery is nothing unusual. I have just checked mine and after 13 hours I have 58% of battery power left and the display has used 75% of it.

How much do you use your phone a day?
Mines is weird. I am already at 82% and it's been only a few hours off the plug.
What the heck? If you check my signature, I think I have a decent build. Ugh. ANy Ideas? PLZ!
i have some thoughts on battery life that id like to share.
our batterys are a " 3.7v" Li-Io.
a typical 3.7 li-io shuld have the folowing voltages...
4.2-4.25 fully charged
3.7v " nominal " charge
3.2v " sag" (voltage mesured when a nominal battery is hit with full rated discharge amperage)
3.0v discharged
2.5v the protection curcuitry kicks in
what ive been seeing on my vibrant is
4.24v @ 100%
currently im at 9% @ 3.709v
im projecting it to die @ 3.700v ie the " nominal " voltage
we are missing out on over half our battery potential.
i remember back in the G1 days when cyanogen lowered the shutdown voltage. i dont recall the values, but it helped.
now, i dont know if this is handled at a kernel level, or in the rom or what.
ive been doing experiments on my wife's hd2 running android, and seen great battery life even with it only having a 1200mah battery
it see's a full 4.2-3.0 discharge cycle
yes i know its diferent hardware, but the battery technology is the same, but we have a larger battery.
theres alot of talented dev's here, i doubt it'll take to long to find a solution to the early shutdown so we can finaly see full battery life.
Definitely sounds like there will be a viable solution to this. I don't know much of what you are talking about but i fully understand it. Cant wait for a solution.

you can change all the voltage, although i dont know if its how youre saying, you can play around with it and see how it goes.

um, no....
thats for reducing cpu voltage.. ie: undervolting...
im talking about actualy useing the battery's full potential rather than pretending its dead when it realy has 60% left.

Ah, ok. like i said it might not be what youre looking for...and i learned something
It is probably done this way to conserve battery life expectancy. I remember reading somewhere that unlike the old nickle based battery, Lithium ions likes to remain stimulated, as it likes to carry active charge and be topped off when ever possible. Oppose to discharging it completely and then recharge the battery. So at 3.7v vs 3.0v, you don't have the battery completely drained so that in long term it doesn't ast at least 2 years like the specification stated (2 years, drops capacity to 80% if battery is well taken care of, ie topped off when ever possible, modest temperature, humidity, etc.)
I am no battery expert just what I though might be the reason.
As stated above, this is done to increase the life of the battery. A LiIon battery can only be power cycled so many times before it looses too much capacity to be used any more. By not fully draining (or fully charging) the battery you are able to get more cycles out of it. Here's more info.
Of course if you figure out how to change the set levels, you will get more time per charge, but you might have to buy a new battery sooner.
I'd be willing to trade increased usage time for battery life span especially seeing as they are so cheap now a days. I'm not a dev or anything but it would seems like the problem is software related not hardware. I've been through 5-6 ROMs all with horrible battery life until installing Macnut R11 and suddenly getting almost double what I was getting before. Changing the battery voltage for better life per charge would be icing on top of the cake though.
right, i understand that for optimum longevity they recomend staying between 40-60%.
we currently are well above that, we are in 100-80% range. 3.7v is the nominal voltage and we are useing that for shutdown voltage. so basicly we are draining the surface charge of the battery as it comes off the charger.
think of it another way: a 12v battery in our car, is it realy dead when it drops to 12v? no.... if i recall, 10.2v is considered dead. and most batterys sit at about 14v just after you turn your car off.. ie: just off the charger...
heat is the primary killer of a li-io battery. more so than discharge cycles. ie: constant heat generated durring charge cycle does more damage than the cycle its self.
so if we are currently only useing the 100-80% range, and we were able to unlock the full 100-0% range, our run time would be greatly extended. the typical user probably charges over night, and durring the day if they think there going to need a top off. thats to charge cycles in 1 day.
lets say @ current useage you get 8 hours use, if we were to unlock the full capacity, we could get an easy 24hours of use, therefor kill the need to have a mid day charge cycle. the overall life span would increse not only due to the number of charge cycles, but also the heat cycles.
this would also make it easyer to stay in the optimum 60-40% range (we cant even drop to 60% right now) providing even better battery life....
i can see if samsung had chosen 3.5 or 3.2v for shutdown, those values would have goten awesome life. once again, it seems that samsung engineers just throw stuff at a wall and run with what ever sticks... hmm... the battery says 3.7v, i guess thats when its suposed to be dead?
Wow this is an interesting thread!

I think a dev should take a look at this , this can be a great breakthrough!
Sent from my SGH-T959 using XDA App
On the vibrant, where is battery percentage calculated? Within the Kernel? Or is solely in hardware? What determines @ what voltage the battery should shutdown?
From what i can tell battery level is set in "mBatteryLevel" And that is set in the Status.java file. ( hxxp://android.git.kernel.org/?p=platform/packages/apps/Settings.git;a=blob;f=src/com/android/settings/deviceinfo/Status.java )
But there is other stuff going on that i have no idea about...
I'd really like something to come of this. Like you guys, I'm sick of not getting a full day out of my battery. Bumping for great success!

Myself personally thinks its basically software headaches from samsung that cause diff problems (bloatware running in background). All the hardware is doing is what its told by the software. If the software says run random apps in background, it does it but at the expense of battery life.

personaly, i usualy get 12-16 hours with moderate use. so i wouldnt say that i get " poor battery life , esp with the early cut off voltage.
I'm running Onyx 3.1 with the Voodoo kernel. Currently at 54% at 3.779v
My problem is with the standby drain-- I'm consistently losing 3% per hour even when sleeping. For some reason this ROM spends a lot of time doing VM swaps. Tried lowering minfree thresholds in OLCF, but system is still way too active.

Actually, I rather like my 1ghz. I underclock to 600/800 to try to conserve battery where possible and my phone runs just as smooth as it does at 1ghz.
Sure a little OC doesn't hurt, but really what's the point right now? There are no "practical" apps out now that demand more than 500mhz, and you can still do more than enough multi-tasking.
So instead of sounding like a pretenteous asshole, either contribute to the topic or shut the hell up.
Now then, I wanted to ask about the possibility of an extended battery for the Galaxy. Something with more amperage perhaps?

After i flashed cm7 a long time ago i noticed that after total charging (100%), when i disconnect the phone it immediately says 99%, i have callibrated the battery and still the same... is not something too important either, but it stills bugging me :/
any help?
btw, it's a red lens defy...
thats just how it is. When plugged in its using the power from the plug and when you disconnect it, then its drawing power from the battery so it will read less. There is no helping it, just what happens it doesnt mean your phone will discharge faster or anything.
99% battery after plug off happens to me always on every rom I tried (even stock one).
Actually I don't care at all.

On stock...? Rally? Didn't know there was a stock ROM with 1% increment. Stock ROM's only have a regular battery indicator and in battery's settings it shows the battery state in 10% increments - 100; 90; 80 and so on...

He said he calibrated it. I calibrated mine with battery calibrator and with deleting battd.bin and restarting with no battery and both do exactly as he says. There is no fix its just that the battery is fuller when plugged in. If you have battery monitor the mV will go down as it stops drawing power off the plug and draws it off the battery. You can never be 100% when you are drawing power off the battery its a simple fact

Well, i had a Moto CliqXT(Quench) running cm7 that keeped the 100% for a while after unplug, that's why i asked... but thanks for the info, i thought my battery was damaged or something like that...
maybe it's something related to the kernel, as the cliqxt have the bootloader unlocked and many optimizations were made to it's kernel... just wondering...
i believe i have found a way to charge the note and maybe other devices faster what i did was in setcpu i set my max from 1.4ghz to 500mhz and let it charge via plug my battery was on 10% after half hour i came back to check and it showed 60% charged this worked for me so i hope it does for all who view this thread

What's the problem with that exactly? (Most issues with battery life are user problems - usually a poor wipe / flash regime and using poor quality apps and heavy syncing. I assume you have used the usual wakelock detection procedures).

1% / 3mins sounds like 5 hours on battery to me. Reasonable, but not great.
Depends if you have your screen on during that time or not, and what brightness, and what tasks it is doing. If that is screen off at all, then it's horrible. If full brightness screen-on for the whole time, then it's ok.

If your phone is the international version, you have the option to buy a new battery And swap it out. I would try this since batteries are pretty cheap at the moment.
If it still drains after all these things only then do I recommend you return the phone for a new one

I would suggest to stop draining processes first. If stopping it doesn't cause any problems i would rather freeze than delet it.
But if it's caused by a ****ty app you downloaded, delete it right away.
if none works, get warranty
