Temperature issue - Galaxy Tab Q&A, Help & Troubleshooting

I'm using "circular battery indicator" application and it always shows temperatures above 30 deg. Now it's showing 33.3 deg and I just turned the tab on 20mn ago! !
The tab is not hot at all.
Is this temperature true or fake? And is the app accurate?
I'm on GB 2.3.3
Wow now 33.5 deg! !!!!!

Battery concern

My sister bought a cherry mobile orbit. Her charging time was two hours.. The battery voltage is 4200 at 100% if unplugged and
4300 if plug. Why is my x8/w8 only reaches 4170 and upon unplugged 4132???

Me too.My X8 charged only about 30mins and it reached 100% from 40%.But when my X8 is in android 2.1 ,it charged about 1.5hrs from 40% to 100%.
Me too
can someone confirm their battery voltage @ 100% and the charging time?
I need only 20 mins from 20% to 98% since using custom froyo (almost any froyo in xda.)
btw what apps you're using to see the voltage?
I am dialling *#*#4636#*#*

wow i need 1.5 hrs
Its all depends on your battery condition and from which % you start your charging...but for me it never reach 4200 at full...
i have the same problem why is that ?
But how many hours?

n7000 battery problem

Hi, there,
My note battery, or maybe system is a bit wired, normally when charging, CPU only use 200mhz, even in screen off mode, but today it was charging on screen off with CPU jumping 1400mhz, so it makes my note like no charge at all, but when screen on and do nothing the note CPU will drop till 200 MHz, any solution?

Do you have better battery stats and cpuspy installed? Have you tried a factory rs? Maybe something is running in background forcing such to occur?
Yup, I have them installed, I have this situation once, but it went well after a couple of battery taking out and cooling down, factory rs was my last touch, if using 3g, with 10mins of online game, the better battery show 13% used for an hour, is it normal?

13% per hour may be normal when 3G on & u r playing games..it may b even more if u r playing some heavy games..about the charging, AFAIK phone won't go to deepsleep during charging even if screen is off..so, processor will be running @ 200MHz..
Yeah I know, but this time it when to 200 on screen on, but 1400 when screen off.
Anyway, I already fact reset the kiddo, and everything seems to when back to normal, maybe is something I installed.
Thank you all for replying the questions.

My Nexus 7 overheating

Recently, twice in the same week, my Nexus 7 has been over heating to almost a burning heat. Now, every night I plug my nexus in and its usually around 30%. Then I put it under my pillow while I listen to a podcast and fall asleep. Then I wake up and usually it fine but today I got my temp gun and it read 138° F on the front glass. I looked at my battery status and it showed that it charged to about 80% and then the screen turned on and the battery was draining very fast while on the charger. I think that is when it overheated and the nexus couldn't vent air cause it was under a pillow. Would this screen turning on be a result of a bug in JB or could it be a rouge app? Or could it be that daydreamer thing that is like a screensaver.

What kernel do you use? Do you OC your CPU and GPU?
Oh, I'm sorry I didn't post those details. I am stock with android 4.2.1 with kernel 3.1.10-g22b4fcd. I am unlocked though

I looked at my battery usage history and my screen turned on around 3 in the morning and its draining the battery while its charging. So something is going rouge.

Download trinity kernel toolbox. This app will show you the cpu`s temp. The normal temp for the CPU on 1.3Ghz is about 60-75 °C...
dont keep your seven under a pillow while its charging,. thats the only way that you will get the battery temperature that hot. for a cpu temperature, 138F isnt hot. but for a battery temperature, 138F is very hot.

NEVER put these devices under a pillow while charging! You are asking for it to get fried. I did this with my phone once, and it was too hot to touch once I took it out in the morning.

OK, that solves the heat issue but how can I find what's drain the battery so fast.

Overheating

Okay, my phone easily overheats if I am charging and using facebook or browser with 3G same time. Also overheats when I am playing Pocket Legends when not charging. If I am charging my phone and Playing Pocket legends, it becomes really hot and just frozes and then reboot after i just unplug charger and leave it alone. This happens in less than 40 minutes. I have a battery app that shows battery temperature and sometimes it goes up to 78 degrees (celsius).
I use cm10 on my phone and never run over 3 apps same time because it causes overheat.
Is this normal for older phones? I have been thinking if I buy that Nexus 4 phone but that is soo expensive in Finland. I haven't overclocked or anything. Can you tell me how to fix this or do i need new phone?
Thanks

You can check with Bat Stat. It's a widget and work very well.
From my experience a mobile completely in idle should stay at 25/30°C, messaging and do some other light things up to 35°C and gaming 45°

There is an app in the system that monitor the temperature.
The phone will shutdown if there is an overheating.

Temperature change means that your CPU is working. That's why you use more battery. If you want to preserve your battery on a rooted phone you can use apps like "SetCPU" and set as max cpu speed 1016 MHz. This will not reduce drastically you phone speed but will help you to preserve more battery. When you want to play some game set the max value back to 1500 Mhz

Atm I was reading a book from Play Books and temp is 29. With my Note I had similar values.
The thing that is different between XZ and Note it's that XZ can't exchange hot cause it's waterproof and Note can do more effectively.
XZ has a front and back "glass" so it's more sensible about external temp.
Here in Italy summer it's coming and I'll expect about 30° CPU temp as normal

CPU???? xD I was talking about batt temp, around the camera gets very hot sometimes... how can I see cpu temp?
but like i said my battery is draining fast, I used to be able to get like above 24hrs on 1charge
and now I'm on 3% in 9hrs... it bothers me...

My fault, i was talking about battery temp. Cpu temp can't be monitored, but i think that is directly propotional with battery temp
Yeah is normal it is a special feature Sony build in. That's foe the winter time to keep Ur hands warm when u use the phone. To bad they do not included a turn off switch for it.

Today I wanted to test how is the battery of this phone. I had unplugged from charger at 6.30 AM and connected to PC for 10 mins during the day. Now I have 33% remain and I went on YouTube, listened songs with Spotify (offline), SMS, FB, Twitter, Viber, Play Book: a normal daily use for me.
I have .253 fw and Doom Kernel with wheatley governor and cfq scheduler. 1026 MHz max - 192 MHz min. Juice Defender Ultimate for mobile data and WiFi always active when I am at home or at work.
About 18h without charge. For me it's an exceptional battery life. (when i hade Note I used to go with 3 more battery in the bag!)
