Lol not sure what happened here.
I left my phone off charge to take a shower at 60%, came out and it was 20%?
Im on MIUI Rom 1.11.11
Is it just bad calibration or something?

Did you also see a significant drop in raw battery voltage?
Most likely the fuel gauge just glitched or reset. 40% in 20 minutes = 2 amperes drain, our device simply can't pull THAT much current, not even close.
Does if really equate to that much? I have seen a few cross ROM battery complaints ND I'm pointing my finger at the Facebook app

Fastest ive had mine drain down is when I left PocketCloud logged into a VNC session. It will run it down close to that fast.
Ya, Id take it off teh charger, reboot and see what it says after that.
When I was running CyanogenMod 7 this would happen all of the time to me. My battery would be at 98% and then suddenly after about 5 min, it would read 50%. I'm not really sure what caused this, but CyanogenMod 7 is the only ROM that I have had this issue with.
I'm now running Miui and I haven't ran across this issue yet.
I did read that calibrating your battery should solve this issue though.
Possibly similar to what a few of us encountered here: http://forum.xda-developers.com/showthread.php?t=1325164
It had to have been pretty hot to draw that much current that quickly. It's a 1650mAh battery. It will provide 1.65A for an hour from fully-charged, until it is discharged. You lost 40% in, say 15 minutes. That's 160% in an hour. Or about a 2.6A rate. Nearly 10 Watts. Sammy spec's a 9 hour talk time rating on 3G. By comparison, this means normal battery usage during a phone call is about 0.18A. Think about how warm the phone gets during a call, and compare that to how warm it'd have to get if you were sucking juice at 14x the normal rate.
If it wasn't really hot, IMO, either there's something wrong with the battery or your issue is "cockpit error".
Minds did the same thing today. I think it was from a old theme I applied.
After the theme was converted my phone started acting funny.
The screen started to lag
Phone got extremely hot without even being touched, just laying on my bed.
Phone kept rebooting
I didn't have any of these issues until I added the theme

It did happen to me too, I just added a new theme (GOlauncher app) and the phone has started to get hot without using it, and the battery goes down very fast.
I've been using my i9300 S3 for a few days now and it seems to heat up on the lower back when using wifi/data extensively. It's not hot to cook an egg sort of thing, but it seems hotter than usual.
Any of you experience such issues?
Hello
I am first time android user. Even i noticed this. Please let me know if it's ok.
It feels normal to me though....but I guess extensive usage may increase heat, just like computers and other electronic devices
I noticed the heat issue a lot more when I just got the phone. It still warms up a bit but i would say it is normal.
Though it did get pretty hot on my last flight during take off that I had to turn it off. Didn't want my expensive phone to melt.

It's normal I wouldn't worry about it to much although it will get warmer if it is being charged while using the program.
I am facing a similar issue ! My question is what temperature is safe enough ? I mean I have used few battery info apps. I have got a temperature reading of around 42 - 43 degree Celsius ! Is it normal ?

Do you own a computer of any kind? Not even that, any electronic device... a TV, PC monitor, anything? Use it for a while, and then report back to me any changes in temperature....
Is quite normal as long as your palm doesn't feel uncomfortable with the heat.

S3 overheating
Krico is absolutely right. It happened this morning when I was charging thru a notebook using both devices at the same time. And the heat lingered on even though I unplugged it. So I switched it off and now it is back to normal. Tks.
The phone can get pretty hot using WIFI and 3g extensively or 3d games. This is normal, electrical components heat up after prolonged use, your computer heats up your tv heats up. As long as the phone isn't burning your hand or exceeding 60C you should be fine. My phone gets warm to the touch and noticeably heats up but doesn't get HOT, if your phone ever gets HOT, turn it off to avoid damage.
I use an app called temp cpu v2. It displays a few interesting stuff incl. battery temperature. There are probably other apps like this.
With wifi on I get around 26 degrees but it sometimes goes up to 50 (or a little more?) on 3d games using wifi.
While charging it gets a little hotter.
After how long does it get warm when you play games like NOVA 3 and such?
For me it does after like 10-20min which is somewhat short to me, but then again, I've never owned a proper flagship phone such as the s3 before.
My phone gets heated up to 47°c after 20mins of riptide.
What's the temperature your phone heats up to? I suggest you use badass battery monitor to check the temperature

Your phone does what?Are you overclocking or something?My S2 doesn't get to 47°C after 1h of NOVA 3 while still being overclocked(Both the CPU and GPU).And the S3 is supposed(And I think proven too) to produce less heat than the S2.
My S3 gets a bit warmer too. Think it will be fixed in subsequent rom releases. Same thing happened with my S2 when I had it; it went away eventually

My s3 barely produces any heat compared to my s2,that thing was burning the flesh in my hands... Maybe that's the reason nova 3 runs sluggish on my phone but not to anyone else?
Sent from my GT-I9300 using xda premium
Has stock roms ever fixed the heat issues through updates in the past (on other phones ofc), or do I have to root and flash a custom rom to decrease the heat?
My s3 also get very hot from both sides after playing 15 mins of shadowgun. I m using stock rom. And yea here temperature is 42C in pakistan lahore!!!

I can't find any details for the Exynos chip in the S3, but afaik most ARM devices have a Tmax (maximum CPU temperature) of 50-something (58?) degree Celsius.
So if it's already 42 outside, you can expect the system to be 52 as air-cooling is terribly inefficient, especially in hot dry air.
When you fire up some games it will thus go above it's threshold and automatically reduce it's performance to keep itself from being damaged due to overheating.
Like the title says. ... What are your phone's temps like? I've read some bad things online about some in the high 40's and low 50s Celsius. So let's see averages (idle, usage, charging)

I've seen mine as low as 84F and never higher then 94F streaming 40+ minute vids on YouTube. at its hottest i've only barely felt it warm just under the flash on the back side.
I guess I'm a lucky one. No issues with the headphone jack crackling no over heating either. Though i do have the wifi issue (I own a D-Link DIR-655 router) that keeps the S$ from staying connected to it but found a workaround. Disable the WMM (uncheck it) and poof, rock solid never a drop since.
I'm on Stock ROM. Rooted with TWRP 2.5.0.2 and about 30 apps frozen
Mine stays pretty cool like that as well. The warmest I've felt mine is while charging. I like how fast this phone charges but it will eventually take its toll on the battery. It usually runs around 35c while charging without using which is new to me. Yours get warm while charging at all?

How do you do this? I saw something you had to dial in another thread but it did nothing on my phone.
Do what? Check temp?
Sent from my unrooted, extremely bloated Galaxy S4 via tapatalk 2.
Yep. Are you using an app or that diagnostic code thing?
I use battery widget from market. It's simple and is not full of bs. Just tells you % temp and voltage

jus got my s4 yesterday.. great phone! but I'm noticing that just doing normal stuff really heats her up. my s3 heated up as well, and it was on the bottom of the phone making it uncomfortable. but the s4 gets warm, or hot, on top. the ear piece gets hot and so does the camera area. I presume this is where the antennas are?
anyway how's everyone else's? good thing I don't talk on the phone often because if that thing heat up my ear I'd return this phone asap lol

It may be your service area. In places where theres low or spotty service or a fringe from 3g to 4g, the radio has to work harder, thus heating up.

Mine gets hot/warm doing normal crap too.. kind of a bummer because the Note2 doesn't get this hot.. just warm at times. I'm assuming this is where the CPU is located, near the center top area where it gets warm/hot.
It's something about Qualcomm it seems.. all of their CPUs love to heat up fast.. seems like the battery percents also drop fast whenever it warms up.
funny thing is that my DNA never gets hot, and that's the snapdragon quad core. and hwen it gets warm, it never breaks 40 degrees C.
the gs4 easily hits up to like 37, 38 degrees C....but even when my DNA is that hot, it doesn't feel that hot. the heat dissipation in that must just be better than how samsungs is. kinda worries me, but my gs3 was just as hot.
i put ktoonz kernel in, which seems to not have the CPU running at full speeds like the stock kernel does, so i think that may be helping. i might flash a custom rom next.
I'm stock rooted so I can't say for other roms/kernels. Mine doesn't break 35c which is a miracle to me coming from the heat plagued rezound where 45c can be achieved just browsing xda for 20 mins. I didn't like how hot samsungs 2amp charger makes the s4 whole charging (even during idle about 35c) so I use my htc charger which is the same 5v but only 1amp. Charges slower but will increase overall life of the battery

ha i didn't even open my s4 charger yet; didn't realize it was 2 amps..i was using the DNA charger too lol
so never over 35? are you on 4g all the time, or wifi? i'm always on 4g and i can easily hit 40. blah. but again, my s3 ran hot too, so i think it's just a samsung thing.
and yeah the rezound was a heater lol i had one.
I know I remember seeing you over there. nice to see some familiar people here. That's on 4g outside yesterday 90 degrees outside Internet browsing and some YouTube for an hour straight. The hottest ive seen was 42 but that was in my car with the sun beating on my pocket with the phone in it.

The only time mine ever got hot is when I used a sleep tracking app which required the phone be on all through the night. Being under my pillow probably didn't help either, but it the battery temperature apparently got up to 45 degrees celsius which made the phone stop charging too.
good to know it stops charging at 45...the rezound didn't lol.
mine right now is sitting at 33.6 degrees C. i'm copying like 6 gigs of music to my sd card. thing is, the earpiece and camera are very warm..the entire top of the phone. can't imagine how annoying that must be when you're talking on the phone...good thing i never make phone calls :\ lol
if you look in system panel or something, you can see that all 4 cores are like always working....and the CPU speed is hardly EVER below 700mhz when the screen is on..i find that odd. my DNA would easily hit down to like 300. it seems like the s4 cpu is always doing something..it's always above 50% on mine, never below. i find that pretty odd...bc idk what it's doing in the background. i put on ktoonz new kernel and it helps a bit, but it's still running often.

god i'm really hoping there isn't a bad batch of ones that get hot. i went through 3 at the store to pick the right one...two of them actually had banding issues on the screen....SERIOUSLY?! i thought we were past that on AMOLED?!?!
they ALL have this very faint veritcal line towards the bottom that's like white when you're looking on a gray background.....every single S4 i've seen. it's crazy. idk wtf it is. this one had it, but the least amount compared to the other 2, but i think i have a tiny piece of dust under my screen. is it really that hard to ask for a piece of technology that's perfect anymore? lol
Do you have power saving mode enabled? I do and trickstermod shows it rarely using anything above 1.3ghz which I like very much lol. Im guessing the gpu and cpu is up in the camera region as it only gets warm on mine when watching videos or having the screen on for long periods.

Holy crap I was tethering using my S4 and charging it up at the same time.. It felt dangerously hot.. I sure hot this doesn't fry the phone, i'm pretty shocked there's not a safety circuit that turns off charging when it gets this hot. This worries me as I rely on tethering for work pretty much daily.. it did seem like once it charged to 100% the heat level went down a bit.
My Note2 gets warmish when tethering and charging.. no where near the heat level of the S4.

next time you do it, check the temp with an app like system panel and report back how hot it was.

If you have a different charger, use that one Samsung gives us a 2amp charger out of the box which is nice for fast charging but is going to cause shorter overall life of the battery and hotter temps. I use my htc charger and it keeps it much cooler, especially when using it while charging

I haven't noticed any heat problems thus far. Sometimes the back under the camera gets a little warm but nothing out of hand
It runs cooler than my gnex!
Gnex and s3 always ran hot for me when torrenting or gaming. My note 2 didn't have this issue. Well because it was probably huge. And now s4 issue remains. Maybe the size of the phone? It always gets warm where the cpu sits on the board. Not a huge deal. I never let mine get scolding hot. But it'll get warm.
