General :: How To Set Minimum Voltage Cutoff (when Device Forcefully Shuts Off)
Dec 3, 2011
I was wondering if there is a way to set the minimum voltage cutoff (when the device forcefully shuts off), if it's device specific then we are working with the HTC Aria. The reason why I ask this, is that I have a device with a 12 Ah (that's 12,000 mAh) battery. Now I'll be straight, I'm an EE so software is not my forte, I work with analogue circuits, not software. So my knowledge of programming is nil. I was going to go the extra mile and make a flyback regulator to keep the voltage at 4 volts all the time (I can get it to work down to .5 volt if I wanted), but did not want the extra mass. (Already have 3 long C cell size sized batteries, don't need a PWM board on top of that). If this is the wrong thread, call me a noob and kick me in the nuts a few times, will ya? BTW the minimum voltage we are working with is 3 volts.

As usual, these are update.zip format. Rename to update.zip, place on root of sdcard, and install (don't forget to 'allow').
My advice to you, in selecting a kernel, is to #1 try the lowV varieties first. Then select the slowest kernel that exceeds what you expect to run on a day to day basis. So if you plan on running 800-1000, run the 1.0lv kernel.
If for some reason you get stuck on the 'M' while booting, first try switching to the mediumV kernel. If that does not work, back the speed down, say from 1.25 to 1.2, or 1.2, to 1.1, etc.
5-slot Low Voltage
1.0Ghz (125/250/550/800/1000)
1.1Ghz (125/250/550/800/1100)
1.2Ghz (125/250/550/800/1200)
1.25Ghz (125/250/550/800/1250)
5-slot Medium Voltage
1.0Ghz (125/250/550/800/1000)
1.1Ghz (125/250/550/800/1100)
1.2Ghz (125/250/550/800/1200)
1.25Ghz (125/250/550/800/1250)
7-slot Low Voltage
1.0Ghz (125/250/550/700/800/900/1000)
1.1Ghz (125/250/550/800/900/1000/1100)
1.2Ghz (125/250/550/800/1000/1100/1200)

All this talk about different rooting methods and how some are unreliable makes me want to learn exactly what's required.
So far from looking at different exploits and methods to root different phones, the most simplest to understand is Peter Alfonso's Galaxy S rooting method posted today it seems all you need is to find a way on your device to install the following:
/system/bin/su (is this included in stock and replaced or just doesn't exist in stock systems?)
/system/app/Superuser.apk (it seems the Android OS has a "super user access" intent that this listens for -- so when apps try to access su this picks app it up?)

I've done some research, but haven't found what I'm looking for. To cope with the memory limitation of my phone, I move some apps to Rom with titanium explorer. Does the rom use the rom partition free space for something? Writting cache, and so on? I have a Xperia J and a X10 mini pro, and they both have around 20 Mb of free space on the ROM. Is it ok? Is there a "safe threshold"?

I'm wondering why the Nexus7 doesn't allow you to slow scroll/pan down at single pixel steps. Always seems to be in 2-3 pixel jumps. I got a bad habit of scrolling web pages while reading from iOS but on my N7 I get these kinda annoying start/stop jerks.
Is this related to the virtual pixel resolution being lower than the actual screen resolution? And would changing it allow one to match the virtual pixels to the screen pixels and get smoother slow speed panning?

Whenever I try to set minimum CPU frequencies higher than the default value, no matter what app I'm using or what kernel or Rom it just won't stick. Governors and maximum frequencies stick though.

I have a sprint Samsung Galaxy S3, rooted...Int he past week or 2, whenever I am in an application (Chrome, Yahoo, GTalk, etc) The screen will sometimes randomly shut off. It just goes black, i can still touch and use whatever app I was in (I can hear the sounds of clicks, etc) and the buttons stay lit on the bottom. When I press the lock button it makes the lock noise. When I then unlock it, i get to the lock screen with no problems. If I unlock into whatever app I am running, the screen will almost immediately shut off again, or sometimes after a few seconds, or sometimes it waits until i touch the screen. BUT, if I unlock into a system app (messages, phone, homescreen, etc) the problem doesnt happen. I have tried adjusting all the display settings for screen timeout, rebooting, battery out, killing services, etc and nothing seems to work.

My phones got a full battery but if I go to take it off the charger it shuts off. I've tried taking the battery out but still doesn't turn back on unless I plug it back into the charge. I need my phone for work I drive the work truck and have to stay in contact with the people at work.

From last one day, I am suffering from this problem, my HTC Desire HD rooted and installed with ViperDHD keeps restarting as it soon as it boots. The phone bootscreen shows, finishes, even the android home screen appears but just for one second and then goes blank and restarts. This all started happening, when I had connected my phone with my computer and a restart occurred, instantaneously.
I have tried everything, Factory reset, full wipe, keeping battery out for 10 minutes, removing SIM and SD card, formatting SD card, even re-installling 2 different ROMs with Full wipe but the problem still persists.
While I do realize it might be a hardware issue but it is impossible go give it up to any service center because it is an imported piece without any warranty. I won't give up that easily. Here are some of the stuff I tried, and some observations I made Device shuts off at bootscreen if there is no SD card, (I doubt that SD card is an essential thing).
I can only boot into recovery where adb logcat or adb bugreport don't work. I tried adb shell find -f | log. None of the log files seemed useful. Is there something I can find here?
What kind of hardware issue might it be? Is it possible to debug it? and what causes shut down? and since I am have some knowledge of computers at lower level, C and linux, is it possible to hack into the kernel and perhaps correct what might be wrong?

I have a Sprint Samsung Galaxy S4 (SPH-L720). My device is currently stock rooted running Android 4.4.2. I recently just did a factory reset and need to encrypt my device. I have my screen lock password setup and when I select to encrypt the device it shows the screen with the android gear icon for a second then shuts off. About a minute later it will turn on again on its own and boot right up to the regular lock screen. It will not encrypt and gives no error message.
The only references I have found on a Google search about encryption not working was referring to an error message saying the encryption failed and asking the user to factory reset.

Any app that will automatically shutoff my Samsung S4 after a set period of time?
What I use this for is I may be listening to a Netflix or HBO GO movie (yes I know, "listening") and I want the phone to shutoff after 30 minutes.
I was having a hard time finding any app that does this. Google searches just showed me results of shutdown problems, and the apps I came across were to reboot the phone.

My son rooted ny Galaxy Note 2 (SGH-i317). After 3D Launcher crashed it, I tried the Galaxy Toolkit offered by mskip. It seemed to work well. I set the phone back to completely stock. (in the hopes of rooting again). But now I get these messages
a) google.process.gapps has stopped
b) Contacts has stopped
c) Gallery has stopped
When I try to dial a number the phone freezes after the first number then suts down. Contacts open in a plain black screen.

(Galaxy note 2, Sungsonic ROM)
When streaming from Grooveshark in a web-browser, the audio-streaming stops (after finishing current song) when the screen shuts/locks. I have tried several browsers with the same result.
Audio-streaming from audio-specific apps (i.e. TuneIn) works just fine.
Someone mentioned somewhere that it has to do with the browsers not being set to over-ride the screen-lock.

I forgot to bring my Droid Incredible charger with me to work. Since the battery was getting low I decided to use my BlackBerry Storm charger on it. The ports are the same, and it goes in without any problems. However, after doing this, it became difficult to unlock. Swiping down usually didn't work. If I was able to swipe down I couldn't get past the "password puzzle." I thought the phone was locked up so I pulled the battery, but it still wouldn't swipe after coming back up. I took the charger out and realized I could swipe again. I repeated this, again plugging the charger in and again I was unable to swipe to unlock. Is there a voltage difference between the BB charger and the Incredible charger? It seems like it was charging it fine. JuicePlotter shows a charge while it was plugged in.

I just installed Cyanogen from DroidMod and while I was at it, I installed the p3 1ghz low voltage kernel. So far, I'm pretty happy. I'm not sure it's been a huuuge battery saver, but I think it's helped. Wifi and bluetooth have been on all day. A few phone calls. Lots of texting and emails. Also some market apps downloaded as well as files transferred on/off. At 8:30 my battery life is at 50%, which is pretty damn good considering how much better that is from strait out of the box on release day.
I'm running 800mhz overclocked, instead of 1ghz to save some power. Should I switch to a different kernel since I'm not even using the 1 ghz slot?
What's the best low voltage kernel for battery life, overclocking included? No need to even bring up stock speeds...
