Hey everyone, what are your battery temperatures during heavy usage? More specifically, while watching a movie, playing a game, or even surfing the web, where the phone can get unusually warm?
My battery temperature has reached as high as 47 degrees celsius. I am concerned considering if you take a look at your battery, there's a sign on it saying that it shouldn't go above 40 degrees celsius/104 degrees fahrenheit.

my phone starts feeling hot at around 86 degrees F. i have a setcpu profile to underclock when the phone is about 85 degrees because i dont like the heat and i figure its not good for the battery to be so hot. before setcpu, i was at around 90 during heavy usage..
My battery temp range is usually between 30°-40°c. Rarely do I go above that temp range. If you are seeing higher temps, there maybe something wrong with your battery. It would be helpfull to know what the thermal limits are, in reguard to battery temps. My rule of thumb is anything over 40° may be approaching the danger zone. I woikd stop what im doing and let the phone cool off.
I got to 52c w teathering. Now i keep it near my window when i do dat.
G2x
mine reached 108F 43C with just the screen on doing nothing else when it's charging. whole top half (back and front) of the phone gets really warm. is that normal?
Set up wifi tether, plug the phone into the wall charger, start downloading on your pc, and watch those numbers fly!!!
The first day I had my phone I did this and I heard a weird beep noise. When I looked at the phone, it had a warning message on it regarding battery temp.
I don't know the temperature it was at though.
mine is at 109 degrees right now and im just downloading stuff off of the charger.
My battery temp is usually around 35-40°, and I am pretty sure it has not gone above that. I don't try to kill the phone, though. If I am downloading a bunch of stuff, that is when it is usually the hottest.
hey guys, it think my phone is becoming hotter than usual while charging, i would just like to ask what is the normal temperature during charging and during heavy usage such as playing 3d game(not charging)
The Nexus has an issue with heating up. Mine does the same. If you feel it is getting too hot, then shut phone down for a bit. Temp shouldn't get more than 120F. It can, but keep that number as a safeguard. Hope this helps.
ok, tnx a lot..will try to monitor the temp regularly
Anyone having charging issue. I ran my shield battery down when I first got it. Then I plug it in to charger. Its been charging over 8 hours and still not at 100 percent. took it off charge at 80 percent. No way it should take this long. I read on reviews it took like 4 to 5 hours.

You used the charger that it came with? And you're not playing games the entire time it's charging, right?

yes I use charger that came with it. and it was charging over night when I was sleeping.
That sounds really odd. What does the battery usage say for the device? Was it awake the whole time? Does it think it was charging all night?

I feel like that has happened on my nexus 7 before. I bet it is an android thing. I would try again and see if it acts up a second time.

when I was charging, i close the screen. so it went to sleep. I dont know how you can tell if it think it was charging all night. I went to battery info and its said 13.6 hours on battery. and 48 percent of that was screen usage. rest was on game and apps.

If you go into the "Battery Info" and touch on the graph area, it'll show you below some bars of time spent on different functions (like charging)

1. Sometimes the battery indicator on Android can take a while to figure out your battery. It might drop 5 percent in ten minutes then take an hour to drop 5 more.
2. The vent area on my Shield seems warmer than the surrounding plastic even when in sleep for a while, so it may be drawing more power than is charging. Just try turning it off and charging it.

Which vent area? Front or back? Because batteries do warm up when you charge them, and those are some big batteries (and a full 2 amp charge)

The smooth part on the bottom back with the model number, FCC, etc. And it's not when I'm charging but when the lid is closed. If I manually power it down then the warm goes away.
i never recommend running your device down when it comes straight out the box. usually i tell people to just fully charge the device first before running it dry therefore it can register the full battery, personally i would not leave a device connected over night just for the simple fact that it can be one in a million that the device might get screwed over a long period of time.
it be nice to know if the problem is fixed or not and what you did just in case others run into this same problem.
ive had no charging issues yet. batts do tend to get nice and warm tho.
but for what its worth i just noticed that im still getting notification sounds from my Shield even tho the lid is closed. so maybe its some kind of hybrid sleep and if you have some rogue app pulling a ton of CPU cycles & its not going into full sleep so its taking longer to charge?
just some food for thought on your issue

Like most Android devices, the device goes to "sleep". Unless you power it off, it still handles notifications, and it still talks on WiFi. But it should consume very little power.

Modern devices use LiPi or Li-ion batteries, these explode when overcharged (seriously, youtube search overcharge lipo). As a result all devices sold with this kind of battery have charge monitoring tools and will disconnect the battery from the charging circuit when full, also they should then run purely from the mains power when the battery is full rather than running on the battery again (they don't like the repeat connect/disconnect effect that would lead to). End result, can't overcharge it.
The heat on mains power tends to be from the voltage regulator. These devices don't run on 5V power like comes from the charger. They tend to use a combo of switch mode and linear regulators to drop the 5V to 3.3V for the CPU and peripherals (3.3 is most common at any rate). Linear regulators in particular get quite warm. Switch mode regulators don't get so warm but don't give a clean output the CPU will run nicely on, they have the odd drop or spike which would either reset or fry the CPU, so generally what happens is the switch mode reg drops a large chunk of the voltage and then feeds it into a linear reg to drop the rest of the way (*the less voltage a linear reg has to drop the less heat it produces). From 5V to 3.3V it is most likely going to be purely a linear regulator, with the CPU and screen drawing at least 1A of current and a 1.7V drop that would equate to 1.7W of heat produced, not much, but enough that if you were to put your finger on the bare regulator chip it would come away red, hold it there long enough and it would be somewhat like those competitions kids have over who can keep their hand on the hot radiator longest That is the main reason they will get hot.
The batteries in these devices are usually 3.7V, that would need a separate regulator from above, and another regulator would still be needed to go from 3.7 > 3.3. 3.7>3.3 would not get so warm. 5>3.7 would still be warm as above.
Never fully drain a LiPo. Gets too low and you damage the cell ir-repairably. When the device claims it is at 0% charge and shuts off is usually closer to 10-20% charge. But that is still considered too low by some people. General advice if you want to prolong the lifetime of your battery is to turn the device off and charge it when it reports somewhere around 5-10% charge.
Batteries do get warm while charging. But my bet is that the voltage regulators would be far more significant heat producers.

good to know. :good: i didnt think closing the lid was the same as pushing the power button on my phone to turn the screen off.
but the OP's problems still might be "sleep" related.
prime example my SGS3 batt life started to tank after the 1st VZW JB update. it took twice as long to charge & would never "sleep" (cuz of the OS not a app) but since the Tegra 4 is a much higher profile chip it could suck a bit more juice if its not being aloud to fully sleep, for whatever reason.
like you said tho, looking at the battery stats could easily tell us if this is the issue.

yes while all this your saying is true i still wont risk it. i say this from experience had a note 10.1 and would leave it over night charging and sure enough it ended up screwing up. might of been there was something wrong with the device itself but still. good post on your behalf though :laugh:
but still im paranoid and prefer to just disconnect once its charge it wont hurt

I tend to go into way too much detail sometimes :/
Disconnecting can't harm it at least if that's what you prefer.
As for info source. Quite into electronics and robotics, intact the shield would make a good controller for robotics purposes
well i did my second charge last night. and this time much faster, about 5 hours to 100 percent. guess i dont have a problem after all. dont know what happen the first time.

no worries lol i tend to get spaced out at times and go into details does not hurt to enlighten people :good:
the problems continue
this time temperature in this device
when I use a fast charge charger the device in a few minutes shoots CPU temperatures above 64C ° and interrupts the charge until it cools down
It also gets excessively hot when playing video games or just watching videos on platforms like YouTube.
is there any solution to this situation?
Try factory reset and if its still persisting, check out the battery, it might got old and inflated. And don't use it while charging it's like you are holding a bomb in your hand unless you don't mind if it exploded...

the battery is new
is in perfect condition
the problem is in the mobile's CPU which is excessively hot
which I don't understand why it happens even when I don't use the device
CPU reaches over 60C ° while using fast charge and device is idle
Hi All,
its been 3 days since i bought the watch 4 44mm, it works great but the charging rate seems to be too slow, as per reviews and such it should take max 2 hours for 0 to 100 but for me its too slow from maybe 25 to 100 it took 4 hours or so, its crazy and the watch is very warm and yes the ambient temp is indeed high in my place but 4 hours for charging??. I have tried two charging blocks 12w charger, and 1 QC 3.0 charger , both seems to be slow only, what block are you all using, I am not sure if my watch is defective
today I checked and found that it charges only 8% in 35 mins
Any suggestions
Did a Reset change anything?
Either way i wouldn't gamble with a new device, you are just 3 days in, so i'd suggest getting a replacement. Excessive heating is bad for the device, it could shorten it's lifespan anyway, and battery is max. 2 days with saving as is.
Put it on a cooling pad and you will see the difference. Install Aida64, you can see the charging rate and battery temperature with it. Keep it below 40 degrees Celsius but not too low either. Perfect would be about 36-37 degrees Celsius while charging.
The charging itself heats it a lot and a hot climate simply adds to it. The system just prevents the battery damage as much as it can, so go with a cooler and aida64 for temperature monitoring.
