This thing gets really hot!! - Acer Iconia A500

I was watching Netflix with HDMI plugged in, brightness all the way up CPU Max 1.5 ghz on demand governor. I set it down on the couch and when the movie was over I picked it up and it was scorching! I looked at my antutu widget and my internal temperature was almost 120! And the aluminum back doesn't help. Has anyone else got their tab this hot??

No, but your usage case is probably detrimental to the device. My suggestion is to not crank it up to 1.5 when doing task that will make it stay there for over an hour.

Agreed... a 50% overclock is in now way called for to run Netflix. In fact, if you playing around with CPU speed, I'd suggest trying to underclock it and see how things run. Less stress, lower heat, longer chip life.

Highest my A500 ever got was 96 when I accidentally left it running youtube under my pillow. Do you need the brightness level to be that high while watching it on TV?

Interactive Vs Conservative Governor? CDMA Battery Life Tips

What is this nonsense people are saying about 4 or 5 hours with screen on and their phone is still at 20%? GTFO.... Usually I would say about 3 hours of screen on and i'm dead. I can get like 18 hrs or so lightly, and by lightly, I mean only using it for a few text and check email, maybe some fb just to check inbox and such, lightly, using the phone (with my reception).
I know the Fascinate is better hardware, and I switched for the GPU among other reasons (2 of em for free...=P) but, on my nexus, I still find that the interactive governor ramped up to the max freq. (1113Mhz) less. Of course, I am using the 1150 nonvoodoo from geeknik, but I doubt I will make it 4 or 5 hours of screen on time.w
How can you use the phone, with the screen on, and not do anything that uses the battery. I mean, without cyanogen, it was cool that I can make it through my day, easy, close to out of box (getting to superclean dj05 is about 100 less flashes that I made it through with the n1/sense/cyan nightlys/test roms/etc.).
But now I want more, the price I have to pay I guess for the .3 inches of gained screen is not using the phone heavily in order to save battery!? That sucks. I used to hammer my iPhone and I rarely made it through the day, but I hammered it with atleast 4 or 5 hrs of screen on time sometimes, and it would make it atleast 8 hours... that thing would idle wayyyy better on GSM Edge than CDMA I guess, as with my T-Mobile N1, it idled wayy better, than this CDMA phone. Is there a way to put it on 1x instead of having it always on 3g? There isnt a setting to uncheck, and you cant get in *#*#4636#*#* on CDMA. I tried that immediately after unboxing to get off 3g when I wasnt using net apps, and usually that gave better signal on GSM, saving battery.
Check out my interactive battery test on my N1 that I did, the interactive setting eventually fell out of favor because it ramps up to the max... instead of ramping up accordingly like OnDemand, and not too slowly like Conservative. Again, why does Fascinate use conservative?
http://forum.xda-developers.com/showthread.php?p=7370179 thats my Interactive Governor Battery Test on my N1 I did in the summer time...
I just wanted to start this thread so we can get a consensus on what works best, and for charging this battery. I used to charge my N1 an extra 1.5 hrs with it off after android says it was at 100. That way it idled on 100 instead of immediate drain. An extra 3 or so hours of battery life if you use it right.
CPU governors control exactly how the CPU scales between your "max" and "min" set frequencies. Most kernels have "ondemand" and "performance." The availability
********I want to be able to choose between ondemand and powersave when my battery gets low. On this phone, as I did with the N1.
ondemand - Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
conservative - Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
performance - Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking.
powersave - Available in some kernels. It will keep the CPU running at the "min" set value at all times.
userspace- A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.

Thank Samsung for breaking ondemand on every sgs phone.
Sent from my SCH-I500 using XDA App
Well what else can you contribute to this thread? Thanks for letting me know that the ondemand is just broken on galaxy s phones. So basically its interactive ... or laggy UI experience. And if you've never used a ondemand kernel, you wouldn't notice the difference but i certainly do. It just takes too long sometimes for it to wake and other things. I have my screen off at 400 mhz but still that is higher than the 256 i was using on the nexus one and it used to wake immediately.
I was reading today and I found that ondemand is pretty much the way to go so i wonder if we could bounty up enough would somebody unbreak it...

You are doing something wrong. Conservative is not choppy on my device and the CPU will always ramp up faster than a human being can judge the response time.

My phone makes it the entire day with heavy use, this means about 20 - 10 min phone calls one or two lasting 30 min, texting my wife all day at work, checking emails, and angry birds for at least 1 hour a day i love that game but I suck at it lol. Something that I found is that the phone will last almost an hour of being on the phone after it hits 0%. In my pocket it lasted 4 hours at 0% the day before yesterday. I thought maybe this is on purpose so you have more then enough time to make it to a charger. When I first downloaded angry birds I played it for three hours straight with the screen at full brightness (i always keep it at full brightness, looks prettier that way) I know it was three hourse because it was while i was waiting at the hospital I got there a little before 7 and wasnt called until 10. Overall I am very pleased with the battery life of this phone not so much with other aspects but battery life and lag never came into my mind as a complaint for this phone, except with all the stock touchwiz stuff.
As adrynalyne said, CPU's scaling changes faster than human's perception. It's your phone or setting that's having an issue.
4 hours at 0%?
The little graphic samsung gives you in the stock battery is misleading.
In my brief experience with it, I got the following impression.
full battery graphic: you have between 100% and 75% left.
<full battery: 75%-50%
Half battery: 50%-25%
low battery: 25%-15%
empty: 15%-0%
This may not be quite right, but you get the idea. It has been a while, but stock battery is pretty misleading. Samsung reports [more than] half empty [always] as being half full!
Want a more trailer indicator? You can get an accurate battery mod (via a theme for instance) or you can download an app to check current battery % left (i use osmanager - do not leave this app running in the background! )
Assuming your phone lasts 27 hours or so unplugged with no use at all, I would say 4 hours at "zero" battery makes sense.
For my phone, the display uses an average of 3.5x as much power as the rest of its functionality (total of 1/4.5x lifespan in active use vs. pocket)
Swyped w/ XDA App. When in doubt, mumble.
I meant "reliable" not trailer.
I get about 5 hours of screen time with little voice calls on wifi.
I don't know if I am just one of the lucky ones but my phone gets between 30 and 36 hours on a single charge, having even made it to 44 hours on a very rare occasion and that's without setcpu profiles even set.
Wtf... my phone is brand spanking new and I get about 4ish hours of screen time on a full charge, with the lowest brightness + screen filter app set at 50.6% reduced light. I get like 3 hours without screen filter on.... wtf. This is running on conservative or interactive the whole time..... wtf!!! With wifi on and 0 extra screens or Widgets using launcher pro without animations... wtf!!!

What's the screen filter app? Conservative and interactive? That's SetCPU?
I wouldn't worry about these guys coming in here saying they're getting 2 days of use either. They're not using the phone anywhere near as much as you. I've had 3 of these things and know 2 guys with them. They all got the same battery life. You don't see anyone posting any screenshots, do you?
Me and my gfs fascinate gets about same battery life in our apt and hers is still DI01 and i'm on DJ05... she has jts 11/16 kernel and i have the 12/21 voodoo5 and we get about the same battery life... dependent on how much we use the phone. .... so just use your phone, and charge it as necessary... its better for the type of battery we use anyways in our phones... **************************************************************************************closed.**************************************************************************************

[Q] Battery got up 114.5*F is that safe?

had my phone charging of my usb on my laptop last night while i was texting a friend, when i noticed that the the Kick stand was getting warm so i checked the temp through my battery widget and found the temp to be 114.5* F I immediatly unplugged my phone and took my case off and the back off to let it cool. I was wondering if this is common or even a safe temp. My setup is as follows
Azrael X 3.1
Net's 2.3 more aggressive universal havs NO SBC
Amon RA 1.8
Max temp for the battery is 60C/140F. I have had temps in that range if I had the screen on for a long time or wifi tether. Around 50/55C though and I would worry.if you notice it often and overclock then I would lower the max cpu frequency.

You are definitely within safe limits on temperature. The only bad thing is the batteries capacity degrades quicker when at a high temperature, but you will probably replace the phone prior to actually realizing the degradation.
Its fine. Mines been a little higher. I don't like using my phone around those temperatures though.
Sent from my Evo using XDA app.
I've read 120 F as safe. So it's close.
General consensus is that using the phone while on USB tends to yield higher temps, but no one knows why.

Whats a safe temp with overclocking ???

I was wondering what some opinions are with how hot
The phone gets with overclocking and when to shut it
Down ? With playing around on the phone it gets to 107*
Fairly quickly depending on outside temperature . What's
A safe and not safe zone for temps ?
Sent from my Rooted HTC G2 with Cyanogen 6.1.1 Stable
If my conversion is right thats 41.67 degrees Celsius.:eek Personally, I wouldnt be comfortable letting it get that hot.
I have a SetCPU profile that if my G2 reaches 38.2 degrees Celsius it underclocks it to 245 (max and min frequency, with performance governor). My G2 has never reached over 34 degrees Celsius though. My daily overclock is in my sig (1.5ghz).

CPU wise it's fine, other parts of the phone and your hand may not be. If it's too hot to hold it's too hot.
Just a note that temperature is the battery temperature and not the CPU temperature.
Sent from my T-Mobile G2 running Cyanogenmod.
I say keep it under 40 degrees Celsius and you're fine.
My phone has only once gotten that hot. I was running a game app on my phone for over an hour straight and I had a case on. Holding the phone in my hand only added to the heat. My temp profile kicked in and I let my phone chill for a while and it came back to normal.
I do not however underclock it to 245 Mhz. I take it down to normal clock speeds of 806 Mhz and that seems to work well for me.
if you dont care about how hot your phone gets or if your watching it ive takin mine up to 1.5 GHz
My nexus one used to reboot at high temperatures. First the screen would become unresponsive, then it would just reset. I think it started doing that when it got into the mid 40s.
So I was just playing homerun battle 3d for a couple of hours and noticed the back getting fairly warm.... Shut it down and looked at setcpu, 117.5F degrees or 38C!!! Hmm lol and its still running like a champ. Might need to set a temp. profile fo sho!

Your conversions are not that great. 40 degrees Celsius is 104 degrees Fahrenheit.
So was your phone at 117.5F or was it at 38C? It can't be both at the same time.
38C isn't bad. 117.5F is quite hot, however.
I'll run the 1.516 GHz OC until the battery gets to 100.4 F. Then I drop it down to 768 MHz. However, when the phone is below the max temp I have it set to 1516 max/256 min (I think it's 256 it might be something else, but I'm too lazy to check). So my phone only starts cooking when I'm running my PSX emulator or something fierce

[Q] CPU

ive just looked at a phone tester app thing, and found out my A500 is only running at 480mhz, how come? tried couple other apps to check and not moved, it should be an 1ghz?
help lol
Like virtually all modern processors, the CPU in the Acer scales its speed to the current required load; running @ 1GHz full time would generate additional heat (and system wear) as well as reduce the battery life.
My tab tends to spend about 2/3 of its time @ 456MHz and underMHz, and about 11% @ 1GHz, the rest being spent in between (with very few stops in the 760/816/912MHz stages.)
If you have SetCPU (requires Root) you can fire up a reasonably complex game for a couple of minutes and check the Time in State info again.
Now, if this isn't the case, what specific "phone tester" app did you try?
Yeah you would not want your tablet running Max CPU speeds all day.
Sent from my ADR6400L using XDA App
i understand about not running full all the time, but its a constant 430.39, it hasnt moved, even using a high end game or anything?
What's a high end game for you?
Because my tabled does go to 1GHz while playing Galaxy on Fire 2.
Get systempanel from the market and test.
If you are rooted, you can use the script i wrote to log clock speed and usage % of both cpu cores while you are doing something. I OC to 1.5 GHz and it is easy to crank both cores to to the max while watching a movie or even just browsing the web.

[Q] Nexus 4 heat problem

I am getting bothered by the heat of my nexus 4 especially at the camera side..., when I play psx emulator it really gets hot and it gets hotter when it is charging... even if i am only watching or streaming the internet it gets noticeably hot, so i would like to know if this is ok or not.
what are apps that could monitor the temperature?
what is the normal temperature when gaming and idle?
I would like to know about this things so that if my unit is a lemon, i could return it to lg for the warranty.
thanks in advance.

you have a quad core device, its normal. when you stress the cpu, gaming, streaming, itll heat up. when you charge, your battery will heat up. the back o the phone is glass, so itll feel like it gets hot fast. when the device hits a certain cpu temperature, heat throttling kicks in. this will lower your cpu speed and cool down your device. when it goes over the cpu safety temperature(100C i believe), the cpu will shut down and the phone will power off. there are several apps that show the cpu and battery temperature. remember, battery temperature and cpu temperature are two completely different temperature readings.
System tuner gives you cpu temp. But you should get an app that tells you battery temp as well...

simms22 is right you can under clock it safely kernel tuner is free on play
Intel CPUs (i5, i7, etc.) can survive going over 100 degree Celsius, but the commonly quoted safe temperature limit for long term operation is 70 degree Celsius. I would assume that the same holds true for other silicon chips, and find it difficult to believe that the shut off temperature for the Nexus 4 is 100 degree Celsius - you will be getting serious burns on your fingers by then.
