[Discussion] Talking about battery life with Android

Hi All,
I've test all of Android builds with lastest kernels but Android on hd2 still eats battery like a T-Rex
My phone survival time not longer than 6 hours on GPRS network.
How about yours?

Come on man, I'm fairly new here but I'm comfortable enough to say... You have to have seen that there are several threads not only on this same topic, but even on how to improve your battery life with Android.

I've try all of these tips not work for me How is yours?

Make sure to turn down the brightness of your screen. There is a thread not far from this one titled "how to improve battery life on Android HD2." Read that. Also put your phone on a charger any time you're near one: desk, car, couch, etc. Disable some of the always on widgets, maybe don't sync social networks or minimize the frequency they sync... the list could go on.
The fact of the matter is these are not final builds and are running from the SD card. A super long battery life isn't to be expected. Follow some if the steps above, read the how-to thread, and give it a shot.
Don't forget to thank the devs who put this together.

With SetCPU running and set up properly, after a day of normal use (around 16 hours) on Shub's Cyanogen's 1.1 build I have around 15% battery left. So clearly you have something setup wrong to be only getting 6 hours. My battery life is now no worse than it was on Windows Mobile.

yeah i get over 20 hours

I got 20 hours with heavyish use for 10 hours, and 10 hours no use.
Which is about the same as i'd get with just winmo.
I could easily use this build for my day to day phone

If I'm using the phone heavily, 12-15 hours. I have no idea how much idle time I would get as my phone is rarely idle as I use it for work constantly... And this is without using SetCPU or any of the battery life tips/tricks honestly. Keep in mind I use the T-Mobile "extended battery" case which recharges my battery with the flip of a switch on my case but I don't ever let it get below 20%.

Hmm I see. I'm starting to thing my battery problem doesn't about Android Builds maybe my SD cards needs a lot of power to work?? What is your android setup? Which build which zimage?

um...that's not a really good comparison.
that's like saying "I can get 1000 miles on one fill up, but I have two tanks and just flip the switch for the second tank".
What do you get with out using the extended battery case?

Sorry, I didn't make that clear. I get 12-15 hours without having to flip on my case. I usually switch it on at around 20%, which is why I said I never let it go below 20%...
Edit: I forgot he asked me which build and zImage as well.
MattC Froyo RC 1.4, 08/03 zImage.

battery "life" is not the main issue here.
in my opinion, the main issue is power management. that causes short battery life combined with high battery temperature.
can the devs say the reason(s) why is the power management that bad? that is the main issue with android builds right now, once it's solved, android can be a true main OS for everyday use.

where do you see a new zimage?
http://cotulla.pp.ru/leo/Android/
just checked and there's none for Aug5?

Other than using the latest zimage and SetCPU to force autoscaling CPU and Conservative CPU Governor, I've noticed Darkstone's vanilla froyo v1 build gives pretty good battery life (vs say, the CM RC1 build) by default.
I've also noticed that I get great standby battery consumption if I ensure that S2U2 is running in the WM background (as iLock2.exe) with the setting "Don't Suspend Power" unchecked in S2U2 options before booting into Android.
On a 3G network with a idle data connection, the (standard HTC) battery only drops 10% for a 10-11 hour standby time.

You get 12 hours with heavy use? Mind telling us what Radio/Rom you are using? What other settings?
I managed to get to 8.5% per hour drain with normal use.
Of course, I never got better than that with WM anyways...

lol i get about 31 to32 hrs (1hrs mp3 and 30min internet) with light use

I must admit my android battery issues were solved with setcpu and screen brightness tweak.
Only funny thing is that with my setcpu profiles identical between Mattc-froyo and Shub-cyanogen, there is a short delay in the latter's response to a key press once screen is off and device locked. No delay on Mattc.....

battery life vs. battery voltage

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!

Also the vibrant SAMOLED display brilliance isnt pretty for free, that sucks up most of the batter right there dont believe me, check ur batter stats ureself. u c HTC, Moto dont have a screen like this right now in the point of time for a reason. cant have both, It dont work that way...Just like You cant have a 1700 HP V24 engine and want 55 MPG out of it too...if this is u then thats pure ignorance. 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.

wow, thank you... ? do you blow every thing out of perportion? nice rant tho....
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?

[Q] Overheating Motorola Defy

Hi!
So I've installed BatteryLife to monitor the percentage of battery remaining as well as the temperature of my Defy, and I've noticed that as I run some apps, it sometimes reach as much as 40°C. What I'm worried about is that it might fry my processor, if I assume things correctly. Will it be that way? How do I solve this?

not use it?
40C is fine.

the temperature that you talk about is that of the battery. 40C is fine if you play some games or similar cpu intensive apps.

Yes 40C is fine!

Yesterday I have 48 C, and the phone was acting normally, so 40 isn't a issue. Also, the phone has cool down mode that activates when it reach critical temp.

mine is normally 37degrees. but make sure your rom doesn't have some overclocking settings and vsel is not set too high.

Once my phone did reached 50°C and I open up the battery cover for better ventilation. I did this because I was on 3g continuesly online while listening music. Phone run no problem for another 2 hours non stop..

what you can do is give us more info. battery temp? cpu temp? custom or stock? the back glass plate is glass so that your quad core cpu can transfer heat through it, thats how its supposed to cool off. thats why it feels hot. has the temp in your area warmed up for spring? btw, the heat isnt harming your phone. if it gets to hot, it shuts down by itself, as a safety. before that, itll reduce the cpu speed to keep it from getting to the shutdown point.

[Q] Overheating Problems [franco kernel | cm 10.1]

After having my phone for around a month, I (yesterday) decided to flip the switch and flashed myself cm10.1 and the latest franco kernel. Just now, I reached to pick up my phone (after letting it idle for around an hour and a half in my pocket), and burned my fingers. The thing is running at 46.5c when the highest it used to get for me was maybe 40-42 (watching a movie, or charging).
What do you guys think the cause is, and my best way for fixing (I dont want to go back to stock, but I will if I have to).
Thanks,

your device isnt overheating nor did it burn your fingers. human body temp is 37C, and it was sitting in your pocket at that temp, insulated, keeping warm. 46.5C will not burn you, ever. it could feel warm because the heat is escaping from the glass back to cool off. thats what its supposed to do. you have a quad core device, it WILL get warm.

think about this.. your body is 37C. 39C is a bump warmer. since your fingers are extremeties, they will be slightly cooler than the rest of your body. since they are a little cooler, your phone will feel warmer. but in reality, your battery temp is just normal, even relatively cool for being on the charger and being used.

Okay, I didn't mean literally 'burn', you're right. My point was that I picked it up and was shocked (figuratively ) by how hot it was.
Again, for the last entire month my phone (on stock) has never reached near this temperature before, even when It was actively running.
[Oh and jacket pocket, it wasnt on me. My point was that it was in a cool, dry, place not charging, and I wasnt using it].

Okay, so saying that makes me stop worrying its going to blow up (happened to my friend's moto milestone back in the day), but it's still a new occurrence to me, which cooincidentally happened right after a changed both my rom and my kernel from stock.
The office aircon is a breezy 24c no matter what day it is .
I was leaning more towards this questions, that I gathered from when i glossed over the two respective threads, but dont understand well enough to decide or check if they're relevant:
-could it be that the rom or the kernel overclocked my phone and thats why its running hotter?
-maybe theres a wake-lock (or partial lock or whatever its called), that had my phone on though it was being left alone?
-did the kernel mess with the radio so now it keeps jumping signals?
-was there an option for 'testicular irradiation' that I accidentally enabled?
Not even sure if these are the right questions to be asking. Definitely not sure what to do about it even if they are...

there could be 1000s of reasons that your device is running a little warmer today, really. it could all just be random too. as long as the battery stays below 55-60C(60C is the battery temp safety shutdown) and the cpu below 80C(95-100C is the cpu safety shutdown). you wont see those high battery or cpu temps unless your really pushing your device(cpu) or watching flash movies/playing intensive games while plugged in(battery). there are safety protocols set in your phone in case it really does overheat.

Just now, I reached to pick up my phone (after letting it idle for around an hour and a half in my pocket), and burned my fingers. The thing is running at 46.5c when the highest it used to get for me was maybe 40-42 (watching a movie, or charging).
What do you guys think the cause is, and my best way for fixing (I dont want to go back to stock, but I will if I have to).
Thanks,

niw we just got to get you to flash trinity kernel with it :angel:

So you think that trinity kernel which runs at higher clock speeds runs cooler than Franco which runs at stock CPU speeds? Mmmkay. Sure.

um, you run it at whatever speed you want. default, it boots up at 1026mhz, with all 4 core set as minimum, and thats recent. before that, it booted up 1458mhz hotplugging, which is still slightly underclocked. just because you have a choice of raising the cpu speed to 1836mhz, doesnt mean that is the kernel default. you should learn about what youre talking about first, before you say something silly.

Yes I did it and it's cool can we add pie control as in PA 3.15 by removing navigation bar shortcut and status bar.
