Camera will not work when battery is low. Way around this?

I hate that if I try to fire up the camera for a quick snap, and the battery is low, it will give me a low battery error before closing the app, and I don't get to take a pic...
Is there any way around this? I searched but didn't see anything...

The camera requires juice to snap a picture. If there's not enough juice it won't even try. Charge the battery. That's the only way around it.

I think that while that is true (that it has to have power to do so), it does not apply here, This is a software restriction, and therefor should be able to be altered. I am unable to take a picture even at %10-%15, which is WAAAY more than it requires physically. ALL of my other phones would allow the camera to be active until the point that the device actually powers off, this one does not, which is software/firmware related...
So?

[Q] Battery charging paused by too high or low temperature

Hi,
I've tried to search for a solution but haven't find any. You know there is a message when battery temperature gets too high then charging stops. The popup message is very very annoying: I use navigation and blackbox while driving. And when this message comes I have to press OK, and 5 secs after it appears again... very very annoying.
I agree with not to overheat the battery but why not just stop charging without this message? Is there any trick to eliminate this? In summer time and sunny days this msg comes very often. I have to place a piece of plastic to car's ventillation hole to minimizing the chance of this msg.
I don't care if it's charging or not, I just don't want to see this msg.
Please help if you have any idea!
I'm on stock JVR now, rooted, underclocked @ 800MHz. Other ROMs (CM7, MIUI) just stops carging without any message.

Had the same problem awhile back,reflash jvr, and dont use undervolting/overclocking programs/kernels.

+1 Dont OC/uV too much.

My apologies guys, but please read: I don't use OC/UV, I use stock and underclock.
With normal use and simple charging everything goes well but under heavy use I get this message while charging. Under heavy use I mean navigation, blackbox, and of course phone is at the windscreen while heated by the sun. The phone's glass is hot. It's normal of course because I use CPU intensive apps.
I repeat: I don't care about charging or not, just want this message to be disappeared.

I just unplug mine from the charger when this pops up. It happens with me in exactly the same circumstances. GPS navigation, dashboard of the car, and bright sunny days, it's not an overclock issue, just high ambient heat source, high cpu usage plus charging.
I also find it's aggravated by the silicon skin case I use.

Yes I'm doing the same as workaround. But other ROMs just stop charging and continue when phone cooled down without any message. It would be very nice to just remove this message by a script or editing a script or something else (I'm not a dev just an "I-like-to-hack" power user).

DO your devices get extremely hot at all? Mine did ,to the point that it was to too hot to handle, im surprised the dam thing did not exploded.
As for removing the message i have not a clue how too, i do know however that is is triggered by the thermal sensors.
I can also recall this happening with my windows mobile devices a few times,this happened when the gps services were stuck working in the background.
In all occasions the only fix a found was to re flash the rom.

No, it's not too hot, it's just warm enough. I don't say it's abnormal because in direct sunlight while charging and using cpu intensive apps it's normal. Just try to figure out is there any chance to do this all without this message...
Ok, I'll wait for someone who knows something or know someone who has seen someone who know something...

Referring to other threads I'm not the only one with this problem and not SGS is the only one with this problem.
While this message is not needed and has no function it has to be eliminated some way because tapping OK is very disturbing while driving/navigating/etc...
Script? Kernel patch/hack? Something? If some ROMs can do it (like MIUI) there must be a way to have it disappeared...

I had the same problem with a Galaxy S II today. First, it began to warn me that was starting charging. And 1 second later it warn the Power Saving was activated and the charger was turned off.
Later, it said 'Charging pause. Voltage too high'. When I've tried to power off the phone, it was powering on by itself.
During the morning, I've used the phone to consume battery. At the afternoon, I put it via USB cable and it seems the problem is solved, for now.
I'm using the ICS ROM beta, by Samsung, have some days.

Your wake locks look just fine....
So it's losing battery when it's completely off? That doesn't sound right at all

yep even when the phone power off i lose battery

That doesn't sound right. I was getting quite a lot of battery drain during screen off/sleep, not as much as you mind, but I disabled Google maps, installed a third party navigation app and tuned Google location settings off and pow...I'm on my second day without charging and still on 50% battery! Really has made a big difference. And the third party nav app works offline so no data usage.

i dont think this will work for me ,what you think about the sensor wakelocks?

Mine look exactly like that. I don't know why audio_out needs a wake lock, but it does. I get about 2% drain per hour though. Really do try disabling the location services. That uses a lot of battery.

help guys

What's your CPU bin number ?
Look at the file /proc/last_kmsg
search for where it says something like [0.602014] c0 1 acpuclk-8064 acpuclk-8064: ACPU PVS: 5
That PVS number is your CPU bin number quality. 0 is the lowest (bad quality & high drain) and 6 is the highest (best quality & reduced drain)
If you've got a PVS 0,1,2 or maybe 3 you should consider going and swapping the phone with your provider.

It's in the /proc directory. You'll need to be rooted to access it afaik sorry

more help guys tnx

This is the second thread this OP has started about the same issue. He refuses to accept that he can't achieve 0% battery loss when the phone is idle or even powered off. I really don't know what we can do for him... :/
See his original thread.

Actually, this is quite correct. No battery technology to date retains charge forever--the physics simply aren't there. As a battery ages, it will deplete if it is not fed a constant charge. Now, I'll grant you that this depletion is VERY VERY VERY VERY VERY SLOW, but it's still there. My Droid RAZR MAXX would be incredibly low on battery in about 4 days even completely turned off.
EDIT: Re-reading the OP's post here, I noticed he cites that he lost alot of battery while the phone was "powered off" for 24hrs. Likely, I suspect he had "Fast Boot" mode turned on, which actually puts the phone into a hibernate mode rather than actually powering it down completely. These are not the same thing.

Set charging limit

Hey all,
Someone on reddit just posted a link to an apk file that let's you set a custom charging limit. Should be a great tool to limit battery wear.

I highly recommend accubattery. It lets you check lots of things like discharging, charging speed, battery health, what apps use how much charge an hour etc and tells you how long you have sot and deep sleep and hibernation etc. You can set an alarm for it to tell you when you get to a certain charge. When mine gets to 80% it tells me in a notification that makes noise to disconnect the charger. Really useful and works great.

It doesn't help when you're charging overnight. The app linked in OP let's the user define a threshold, such that the phone doesn't get charged beyond this threshold, regarding if it's plugged in

Download automate, theres a flow that lets you choose what to limit it to. you will need the premium version of automate though

LED Flip Cover Always On, Possible?

Hello, I have this case and I wonder if it is possible to make the display always on. In that way I can see faster any notifications...

VERY GOOD idea !!!
I own the led flip cover and it's very great and wonderfull but much more great if AOD available ... but what battery drain effect if it's possible or hack made it ?

I don't believe that a few leds will have a huge impact in the battery drainage. My personal opinion is that I am ok with an extra battery drain, in order to achieve the result I want. I believe that it would be very useful to have AOD the time and if you have any notification the LEDs to make a loop showing time and notifications ( I don't know if I expressed my thought correctly in order to understand it)

This. I agree completely. This should be an option inside the icon editor software.

Have you found anything?

I agree!
I agree, they must do something and show at lees a notification light.
I notice that the led view not working on wireless charger.

it is working. But only when LEDs are off.
