General Warning: Overheating!

Just a warning to all using the FreeX10/other 2.2+ performance ROMs that I experienced is the overheating of the device. This may only be me, but I'm posting this just in case.
Quick details of my X10:
Flashed to FreeX10 Beta #4 last night.
Used SetCPU to set scaling to Performance and minimum clock speed @ 998MHz.
Using the 3G (build.prop) enhancement modification.
I have a rubber casing around the phone.
Usually connected to WiFi.
My phone has been on since last night and has been charging for most of the time since then and now.
Just then, I decided to turn my phone off a couple of times. I did not notice the heat from just holding it. I was browsing here and read a thread about removing the battery, so I just did that for some reason. It wasn't until I opened the case when I could smell the smell of melted/hot plastic - it was coming from the battery. I immediately placed the open-phone and the battery in front of a cool fan, the battery and phone both started to cool down and the smell disappeared. I couldn't find any liquid/melted plastics anywhere on/in the phone, but I could definitely smell it.
Just a general friendly warning (that can't hurt). Not sure if it's documented or not, and whether this is only Froyo or below/above.

Used SetCPU to set scaling to Performance and minimum clock speed @ 998MHz.

what's the point?! if it is to overheat your x10, mission complete

Why using setcpu? I use the same rom and it runs like hell without setcpu. No overheating neither...

nytral is right. You set the CPU to run @998Hmz at _all time_ so it'[s only natural that the device/battery overheated.

u have managed to make a perfect guide on how to overheat the phone...
u push all the components to their max working capacity (full cpu, 'enhancement' of radio) and on top of that u keep it enclosed in a rubber casing...
bravo!!!

Sorry, Min is 245. Not 998.. :-/
And I'm pretty sure the material of the casing (rubber vs hard plastic) wouldn't matter, but would contribute to the heating. I'm sure that a lot of people would use a case of some sort to protect their device.
The only reason why I started this thread is because I was on a ROM not too long ago (a couple of nights ago), which has exactly the same settings and modifications, except, it wasn't running Froyo - it was running Eclair. And since I installed that Eclair ROM, the phone has only been turned off once (with the battery removed, about a couple of days after installing it and it being on and charging pretty much 24/7) and has been charging pretty much non stop.
The only difference is it is using Froyo instead of Eclair... Hence why I thought it'd be best to start this thread.

LOL, now this is n1 example of a person who didnt read before he flashed
Solution dont whipe data...

lol nice overheat guide
i'm using setcpu to scale it to powersafe and max @512 Hz
and when the screen is off it's max is set to the lowest (256?)
and when i wanna play games i always set it to min 256(?) and may 998 ans performance
then my battery won't drain so fast

nice overheating guidelines

Do you guys actually see a difference with setcpu? I have used every option available and nothing ever got slower or faster for me.

Yeah I'm running 2.2.1 and my X10 is no where near hot. well, at least in temperature because its a hot-sexy phone ;P
Nice overclocking there though X10 watercooling systems now in development, expect another forum branch to open in XDA in the next coming weeks.

To my understanding the 2.6.29 doesn't support overclocking so setcpu shouldn't make a difference at all. The rubber case probably contributed to the heat retention but the heat likely is from the constant charging.

Try the JuiceDefender app and set it to turn off wifi and data when your screen is off or unless certain apps are visible, helps with battery and stops unused functions while your phone sleeps.

Phone doesnt overheat, if you use it right.

Useless topic!!
Sounds like a guy (not saying names) that Z tells to remove some files from "some" roms he was taking without permission, just trying to desestimate Z rom.
Beta 4 runs very well, theres no overheat.
Sorry for my bad english!!

I have installed cm6.1. 3 v4. 3, its a fab rom.... but charging is the main prob... even if i charge for 2 hrs continues it charges upto just 60% and it becomes very hot..... any solution for this......

Try charging the phone while its off. Ive heard people say that their phone wouldnt charge past a certain point but after charging it whilst off it returned to charging back to 100 percent. I bought a new usb cable for my charger after the terminal end into the phone became deformed and my phone now charges ~3x faster but ive never had it get abnormally hot.

Hmmm... i set cpu to 998 when running emulators, otherwise its just ondemand. Using freex10 b4 for a fortnight high use frequent charging added 3g build prop lines, got no overheating issues.

Its funny that anyone with the know how or has supposedly read these forums continue to pay for (or pirate!) apps that have no effect. WITHOUT UNLOCKED BOOTLOADER AND CUSTOM KERNEL OVERCLOCKING APPS HAVE NO EFFECT! Check the overclock option in JuiceDefender, this option is not supported! The developer of the app has apparently left out any notice that it doesnt work with our kernel so they can continue to make sales.

Screen Brightness in EC05

i dont know its just me or the screen is brighter than DI18 , bcz the screen even in the lowest brightness is killing the battery more than eclair .
I just got like 3 hours at screen usage , please let me know is a common "issue" or just me , or more tips to improve the battery performance bcz the phone can be like more than 5 days in standby like calibrate battery or something like that i dont know (i dont have the phone rooted)
Also the battery goes warmer than DI18 like 104 ºF i think is a normal temp for heave usage but i got less in DI18

Thought it was just me. I have brightness all the way down and it's STILL bright.
Will have to try out the app Top nurse recommended. If I have my phone hooked up to my PC and the brightness all the way down and i use it to send texts or surf, it actually drains my battery. Phone also gets really hot.

i´m going to try SyndicateROM - Frozen expecting it have the same brightness level of eclair DI18

What settings are you running with this app nurse?

For the time being I'm done with custom roms. I find that they introduce some quirk or the other that ends up annoying me. For now, stock and rooted, crap ware removed and getting decent battery life.

All it does is choose how bright the phones screen is, but it can go dimmer than the phones settings. Set t any number you want, just (caps lock for emphasis) DO NOT use zero.

[Q] Auto Brightness Changes Extremely Frequently

I got my GT 10.1 this past Monday and I have noticed auto brightness changes quite frequently. I can't figure out why. I don't think I am blocking the sensor but I don't know where it is...
Has anyone else had this issue? It's making me dizzy so I just turned off the auto setting but it seems like it should work.

Yes, mine does the same. I assume the sensor is next to the front camera, which I'm not obstructing. But the brightness level will change rapidly. I had to disable the feature. Found it default to a level too dark most of the time anyway.

I agree with it being too dark. At least I know I'm not the only one with the issue.

Same issue with me. Turned it off. I read that auto brightness burns more battery than full brightness cause it's constantly asking the CPU to make a decision regarding brightness.

Interesting. I always thought that one if the purposes of auto brightness was to conserve the battery.
Sent from my DROIDX using XDA App

I had this problem too. It would constantly change so i had to disable it.
Maybe samsung can put a fix out for it.

I imagine the algorithm included is very simple and uses very few cpu cycles, so I doubt it has an impact on battery life. Especially since it probably doesn't (shouldn't) run when the screen is off, so it shouldn't prevent the device from sleeping.
I agree the levels they have set are much too dim and make auto-brightness just about useless. I had the opposite problem with my Captivate, where the auto-brightness as too bright. Fortunately CM7 allows you to adjust the levels for auto-brightness. I hope we see something similar show up in a custom rom for the Galaxy Tab 10.1
Anyway, I keep mine set at 20% and that seems to work pretty well for me.

Where do you see the brightness percentage? I have a slider but don't see a percentage anywhere.

It's an approximation on my behalf.

I notice the same problem especially when holding the device vertically with my right hand on the front facing camera. I guess the ambient sensor is located somewhere where my hand is and thinks that I'm in dark room and automatically lowers the brightness. I also noticed that the brigthness change whenever I touch the screen so i guess its listening every time you touch the screen unlike the ipad where it refreshes evertytime it wakes up.

Automatic Brightness... Bonkers, help please

Hi,
I bought a Nexus 7 32GB Wifi version yesterday from Carphonewarehouse.
I brought it home and it asked to update, I let it update to 4.2, with automatic brightness my screen is very dim, I mean its not nice to view with automatic brightness as it seems to dim the screen to much.
I know people are having problems with latest update etc, as I updated immediately when turning on device etc I cannot be sure if this is due to the update or it was like it before the update, I would like to use automatic brightness to conserve power but it seems to dim the brightness to much and I also notice the brightness level adjusts quite a bit in same lighting and is very noticeable when viewing screen.
When using full brightness the screens brilliant.
Is this part of the 4.2 bugs ?
I disabled auto sync for Google Currents to help some performance issues for now.
As this is my first tablet and updated immediately I can't compare differences between updates to know if its just a bug.
How long does it take to charge the tablet fully approx ? as mine seems to take ages, again I am aware this is possibly another bug after 4.2 update.
PS: I here that I should have got a £15 Google credit but never got an email and I had to pay by card when I purchased a £2 app as no option to choose Google credit only to pay by card. Was this a limited time offer or something as am gutted I not got it ?
Thanks for any help/advice!

Hi,
Unfortunately the screen flickers issue is a well known issue to nexus 7. Since you just bought it, I would recommend exchange it and hope you get a good one. Mine is having the same issue but I kinda get used to it. Good luck...

If automatic brightness does not work the way you want turn it off. Flicker gone.
It is a checkbox under settings / display.
I like mine best with brightness set to about 50%. An added bonus is that really extends battery life.

I highly suggest giving lux a try. I bought it because I found the minimum brightness on the n7 was too bright for night reading. It has a lot of settings to tailor the auto brightness to your taste. I turned off the android auto brightness and set the manual brightness almost all the way down and let lux adjust it from there.

4.2 totally screwed up automatic brightness, made it super sensitive. best option right now is to turn it off and change thaw brightness manually

Thanks everyone for replying, gonna just turn off auto brightness and set it to 50%, its ok at 50%, thanks much appreciated!
Fingers crossed an update will sort the sensitivity out.

What does the flicker everyone refers to about auto brightness look like? I don't think I experience this issue. It may be the lighting I have around doesn't cause it.
What I DO have an issue with is low brightness either manual or auto in dim rooms where I don't want to be blinded, is the flickering caused by WiFi signal being low. This isn't the same issue others refer to here is it?

If it flickers on manual - you have a different issue.

Some devices have screens that are significantly dimmer than others on all brightness settings (I've had 4 so I should know). I've got an n7 that the screen is virtually unusable on auto under some conditions. I complained and got a replacement and they've never bothered picking up the faulty one. My Mrs has it now and it doesn't bother her but, side by side with my n7, its a massive difference. If it bothers you return it because it'll really get on your nerves after a while.

my device died anyway so took back for replacement. I decided not to update to 4.2 as auto brightness works excellent without update and no bugs either so will wait for a more stable update, much happier now. Thanks!

Disable auto low brightness on low battery

When my battery reaches 5% the screen dims (probably to the lowest brightness possible) so much that when outside the phone is not usable because I can't see anything and the brightness slider from the notification bar disappears. Is there a way to disable this? btw power saving is turned off.
Also does anybody knows if the phone slows down cpu/gpu when on low battery because I've been playing some games on low battery and I think they were a bit "laggy" but power saving was turned off.

Also interested

Me too

Also trying to find a solution since more than 1 week. Until now i've no clue
Thats really annoying an i hate Samsung for that - It's strange because my girlfriend owned a S3 and she don't have this :silly:

OMG I`m not alone in this problem. waiting for the solution patiently

I hate this feature as well, but it's on all phones that run android
It's built into the system
At 5% power, brightness goes to minimum
It's good feature, but when you have extended battery, it's really annoying with still a lot of power left. Screen becomes pretty dark.
And the fact that power of extended battery does not show correctly, it's 5% us not even like 10, but could actually be like 20, makes it even a bigger problem

Any ideas how to fix this issue ?

There's no actual way to override low power at 5%
It's built-in android.
If you really need backlight, get app in market, called adjbrightness, that's one word.
It can override brightness to any percentage you details yourself, it actually guess from 0-255, but it won't Activate auto brightness, since that blocked by android due to low power.
So just use that apply if you really need more light on screen till next charge cycle.

You need stock rom and stock kernel
Otherwise, everything is messed up.
You don't have necessary modules for the program to work with.

5% low battery no brightness adjustment
This is absolutely bs! I really can't stand samsung for doing this the only thing that I would say that puts samsung a downfall. I tried to do the same thing and rooted or not makes no difference. My guess is that it must be custom rom med or at least hack the binary and system to customize. Example remove enabled 5% lowest brightness from the system and identifying what the name of the file of system thats corsing the problem.

worked for me!
Wow you are my saviour. I've been having a problem with my battery showing a fualty value after rooting my galaxy tab 4 with stock ROM and kernel. My battery always reads 1% even though I charged it not too long ago. I can finally use my device again! Thanks so much!
