[REQUEST] simple app: Help with overheat problem

Hello,
I need a simple app to help with an overheat problem on my EVO.
Let me recap the problem simply, when the phone gets too warm it will shut down and vibrate five times and then blink the green LED. The phone then cannot be turned back on until the battery has cooled down.
I have found a half solution, if my phone is in Airplane mode then it will not shut down even when it is warm. So, to avoid shutdown, I need a simple widget. The widget should be 2x1. On the left side, a simple battery temp monitor. On the right side, an airplane icon to let me know if the phone is in airplane mode or not.
What I need the app to do is to automatically switch the phone to airplane mode if the the phone gets above a user designated temperature. The only exception to the automatic airplane mode should be if the phone is in a current call. Seems like the phone will let me finish a call before shutting down due to heat. Hopefully the app can throw the phone into airplane mode immediately when the call ends. But if that exception is too difficult, the primary functionality would still be worth it.
This is my first app request, so I don't know if I'm being specific enough. I also know that other people can use this app. Hopefully someone out there can help us all out.
Thanks

There is an app called tasker that should be able to do that for you. At least untill someone can build an app for you.

Not sure what your doing to over heat the phone, but I would try to fix the problem instead of usong a work around. It sounds like you have an inefficient kernel or its too far ovrrclocked. I'm thinking continual use in this overheated state will cause unrepairable damage to your phone.

Just looked at Tasker, from what I can tell it does not have Temperature as an event.
And the problem cause is not my kernel, from what I can tell. I've tried a few different kernels on a couple different mods. I've tried underclocking and under volting. Nothing seems to help. From what I've read, I might have a faulty sensor.

I had a hell of a time with cm7 and the jit compiler. Poor battery life and running warm even when browsing the web. Not sure what your running but it may be as easy as tapping a checkbox.

It's a hardware cpu sensor calibration issue, according to Sprint tech Lokifish Mars. Search for my thread in Evo General.
I avoid shutdowns by keeping battery temp < 39°C.

mine overheated when i was charging and using hotspot/tether, somehow after i wiped my sd card and everything else and installed the rom again it never overheated again.
somehow the more apps get installed the more the chanse some of them be are gonna be running in the backgroung, who knows...

Some phones overheat and shutdown regardless of installed apps, rom, or kernel. My Evo consistently shutsdown at 39°C, even when running bare aosp w/zero apps installed.
It's only an issue for me when playing games, using the phone in high ambient temps, and flashing mods. Keeping the battery & cpu cool with a fan or ac vent is the only way I can flash mods or roms.

Elixir is a free app on the market, you can make customizable widgets (1x1 up to 4x1), one for temp, the other to toggle airplane mode.
I use it to monitor temp, battery, cpu freq, and cpu %, and to keep an eye on ram.
Works well.

[Q] Automatic wake up when connecting power or USB

I'm running Nova and CWM9 and whenever I connect the phone to USB or a charger the phone wakes up automatically forcing me to push the power button evey time I connect it to turn off the screen.
Anyone know if it's possible to disable this "feature"?
Thanks!

I believe stock does that too. That would be an interesting tweak if it's not already around! In terms of disabling, I'm not sure there is an option to do so.

Confirm stock does it as does Apex; presumably it's set somewhere basic in ICS

Its in developer options. Untick 'stay awake' (if I understand the question!)

And this is a problem why? Its just indicating to you that its plugged in properly and charging... the screen will time out and turn off a few seconds later.

Thanks for checking!
It is interesting that Google would assume everytime you plug the phone in (and unplug the phone) you would want it to wake up. Considering the short battery life these phones have, lots of charging would be commonplace and therefore lots of connecting/disconnecting without the intent to actually use the phone.
I could see giving people the option to have the phone do that - but for me the unplug wakeup is especially annoying because I have to turn it off everytime I go to put it in my pocket.

Well considering by stock there's no charging LED indicator, turning the screen on momentarily to indicate a charging state is a smart idea.
Also, if you're plugging it in, why are you worried about the battery drained by keeping the screen on for 10 seconds? 10 seconds.

Well that's that I thought too, but sometimes it doesn't go back to sleep like it should and I'll notice my pocket getting quite warm pull it out and it's still on.
It could be a bug in the ROM I'm running (not going to sleep correctly all the time) but I don't remember my DINC doing that so I figured it was something that just needed to be disabled.

Hmm, I did have this option enabled - mainly because when I connect it to the charger I do like it to stay on -prime example using Slacker Radio in my car when plugged into the dock.
Maybe I'll try a different ROM since it seems the problem isn't so much that I need to disable to wakeup on connect/disconnect but instead I need the sleep function to be more reliable so I don't have a mini oven on my pocket.
Thanks!

A great option for your car dock needs would be to introduce something like the app Tasker. Then you could leave the screen off but have tasker set it to constant on and load slacker when the Bluetooth connection to your car happens.

Battery icon or battery information not showing charging but still is why?

Just trying to get my head around this dumb battery charging issue. Seems that some Roms the wife's kindle charges but doesn't say/show anything is actually charging. Some Roms show charging under battery information. All Roms don't show battery charging icon. Also the light on the power button works or doesn't work. Can someone explain all this so I can understand.. Its pretty bizarre.. Thanks

I will try to first give you the short answer then I will make an attempt at the long one. The charging issue is directly related to the kernel.... the long one... the icon will not indicate charging ever... go to about phone or tablet and status plug it in if it still says discharging unplug and replug if it still say discharging reboot then try again.. its common for the light to flicker amber when charging and not remain static at some point it will go green near the end of the charge... bottom line its just the nature of the beast...high usage fast or slow charge erratic indications all part of the animal...

Thanks for the explanation! What you mentioned is exactly what we have been seeing. It does charge so knowing its kernel related thing works for me.

I'm having a similar problem, I know it charges by going to the settings menu. The problem comes from when the Kindle goes to sleep, I always had a light come out of the button, but after installing Jandycane the light wont come on. It's hard to know if it is charging or not, anyone have the same problem?

Everyone has the same problem that's just how it is on JB and I believe ICS roms. The kernel needs fixed, but there are other issues that are most likely higher priority.

I have Hashcode's kernel and have flashed many ROMs. I'm on Hellfire's now . I find that if you charge in TWRP the light acts normal, stays red while charging and turns green at 90%. It may be my particular kf but try it , it might work.

[Q] Does anyone know how to turn off the LED light?

I think the LED light drains my battery too much when the screen is off
any way to turn it off ?

Are you on ICS or JB? I thought on ICS there was a direct setting but can't remember what option under System Settings. Maybe "More Settings"?
If you're on JB, can you do it through Settings -> Blocking Mode?

I think "lightflow" from the playstore gives you the option to turn it off

Think it depends on what ROM. What do you have enabling the LED when screen is off? From what I have read around here it really doesnt drain battery.

Should work. This way, you can disable all LED indicator all the time or for a selected period of time -- i.e. during the night.
More LED options are available in Settings -> Display -> LED Indicator, you can select which type(s) of LED indicator you want to activate or not (charging, low battery, notifications, and voice recording). It may then be interesting to configure these settings in conjuction with the blocking mode.
But that's on stock ROM. It might be different in CM10.

The S3's flashing led has negligible battery drain. (my experience)
I am using Light Manager app on a Stock ICS rom in normal mode blinking rapidly and have done the A/B tests to confirm that it is the least of your worries. I am a battery saving nut and have lots of experience with this.
But I would say, that some LED control apps have been known to cause heavy battery drain both to wakelocks and/or just the way they handle the switching.

SGH-T989 (T-Mobile Samsung GS2) - 66% wakelock (KWL) after placed on charger

I have a T-Mobile Samsung Galaxy S2 (SGH-T989), with TWRP 2.6.1.0 recovery, rooted with Stock Jellybean 4.1.2 and have an issue with a pesky wakelock that I can't find. This wakelock sets the CPU to 66% of max (1080mhz) and holds it there. It occurs whenever I plug in the power cord and the wakelock will remain in affect until the phone is rebooted. A soft-reboot (using either Xposed Installer or Android Tweaker) will not break the wakelock. Only a full reboot, where the phone goes black and the Samsung progress indicator stripe is displayed will remove the wakelock. The soft reboot that just shows the Samsung GS 2 splash screen won't cut it.
Any idea where to look. I think this is a kernel lock bug since a soft boot won't clear it. Is there a compatible replacement kernel for the STOCK 4.1.2? I tried Beanstalk 4.3.1 but had lagging and didn't want to lose the Wifi calling feature from stock rom.
If there's no replacement kernel that is compatible with the stock 4.1.2, how about a replacement rom that supports Wifi Calling which I understand is deeply rooted in TW and the kernel?

its been a known issue for a while although it has gotten alot better than before ... reboot your phone every time you take it off the charger or you can try cpu sleeper your phone will be in a COMA! lol also anything google with make your wakelocks sky rocket , location access etc.. try cpu sleeper see if it helps first ?

Yes, this!!!
Don't know about cpu speed, never checked....but my phone won't sleep while charging ever. Always thought that was normal. And a full reboot after unplugging the phone, every time, is a habit I've had for a long time. It used to, still does, cure a few issues. One used to be media scanner. It would run wild until you rebooted after a charge, or force stopped it. Another issue has to do with chargers other than the Samsung one....phone would not sleep after a charge.
So anyway....unplug and reboot. Every time and you'll be fine after charging. Unless its another issue completely.

I've seen that JMT supports Wifi Calling. Do you know of any other roms that still have Wifi Calling? Also, since the latest stock rom was on Android 4.1.2, does this mean all custom roms that provide Wifi calling will be on 4.1.2, or is a higher (4.2.1 or 4.2.2) available with that feature?

You might have to go back few pages on the development thread, but anything that is TW 4.1.2 will have wifi calling. Jamison904 has one Rushing has one a few others I'm on my phone so can't link them but give it shot :thumbup: an as always make a back up

LOL. Of course I've used cpu sleeper....it was great!! Just haven't needed it in some time.
I meant I never noticed what my cpu is at while its charging. Pretty sure its not over 1000....
Hopefully deep sleep won't be an issue on my G2 when I get it. Come on Christmas! My 5 year old daughter is getting a galaxy tab 2 I think. Want the sd card for her movies. She filled up our N7 fast! LOL Is cpu sleeper for any phone??

FYI, I did confirm last night that the wakelock is not taken if the phone is charged on USB instead of AC charger. I charged last night using my USB port and I was even able to power off my phone (to the "charging" indicator at least). Usually the phone will not power off while charging on AC. It will power down and then start back up automatically. I'm using a PPA 2.1A 4-port charger but I think this also occurred on the Samsung charger as well. It seems to be that the wakelock that is taken due to the AC charger gets orphaned after the phone is removed from the charger, but I still can't explain why the phone won't power off when charging on AC.
