How hot does your S3 get?

When I'm on mobile data with GPS running, I noticed the bottom of half of my S3 getting pretty damn warm. Is this normal?

Just started using mine I'm feeling the same heat

Are you guys all running stock kernel and ROM or custom? I'm on stock.

Ha! Try hours with GPS, Bluetooth music and Tethering on... the heat seems to really hit while I'm charging and doing all that. Fact! I can't touch the ass end of the phone. It probably gets about 8 hours a week like that. Still working perfectly. Samsung tells me it's normal. It also has a lot of factors for me too. I use a 1 amp charger. After 96% it's not so bad. At night when brightness is down. Not as hot. I tried to get it to mess up but couldn't. GPS, Bluetooth, tethering, charging from 30% and 100% display, and I pushed out to a low coverage area. Didn't miss a beat or melt. Lol.

Navigation makes phones really hot, but with normal usage it should stay within 30-36°C.
I like this phone's heat management more than my old phone. My Evo 3d would get hot from 10 min usage.
On this, my screen has been on for 2 hours straight and I'm running at a cool 35.1 °C.

When I was running CM10 for a day or two I thought my phone would melt but it was also 90+ degrees outside so it was hard to tell. My phone gets a little warm, but nothing too worrying.

When you downloaded that, were you on stock ROM and kernel?

This is to be expected. It is pretty high clock rate too but seriously a huge improvement from the gs2

It actually shouldn't be expected. The Snapdragon S3's also ran at 1.5ghz and was pleasantly cool and the Exynos on the Galaxy Note was at 1.4ghz. Both are less power efficient and should run hotter than the S4. I've used the Evo LTE for a while with the same S4 and it barely got warm on a hot day. The issue is with the second core being weird. For those that hasn't already, make sure you flash Freeza's fix, http://forum.xda-developers.com/showthread.php?t=1790061 . This fix made my phone cool and got rid of my quickly draining battery life.

Most of the time my phone will stay within "normal" (to me) range, but when I game heavily... it turns into an oven range! I've gotten so paranoid a few times, I took the battery out and let it cooled for 5-10min

Im having the same problem....it isnt the software thats causing this its the hardware
Sent from my SPH-L710 using xda premium

I hope you guys will repsond to this... What do you consider to be "normal" temperature for your phone to reach? Is 35 degrees realy normal? Ive heard people with s3 talk of theirs only reaching temperatures of 29 degrees max.
Thanks.

I get phenomenal battery life out of my S3 (stock).
I had an Epic 4G and was afraid to leave my desk because of the battery drain. With moderate usage (30-60 mins talk time, texting, chat, some web, exchange, ect) I can easily get 16-20 hours. Signal quality in your area will impact it more than anything. Also, wifi is vastly easier on the battery.
PS Facebook app SUCKS. Just bookmark the webpage and use that. Works better and doesn't ruin your phone.

I think it depends on how its configured. I've seen it eat the battery but also not use it much at all. Been a bit since I messed with it though so don't remember what settings made the difference.

Post a screen shot and I'll tell ya what could be happening.

You can improve battery life by switching to custom roms with less bloatware, and updating to more efficient kernels. (This is on a Rom/Kernel level)
Software wise, just figure out what apps are causing wake times and try not to use them. Basically whenever an app/widget refreshes/updates content, it may cause phone to wake (like weather/clock widgets for example).

I have been using cpusleep and it seems to have helped my battery life ... also using a custom rom without the bloatware is key for me.
my current setup is freegs3 release 6 with the latest trinity kernel...even though its overclocked my battery has been amazing and phone has worked flawless.
Im also using system tuner which has given me the ability to manage the cpu with on demand and other customizable settings
The only thing I synch is my k9 mail account
I also have frozen several samsung apps which helped...
Im now getting over 20 hours of basic use between charges...I dont use games/videos so might be a little skewed . I use this phone for business calls/internet/messaging/photos/navi...pretty basic

I have been using Gigajoule lately by feckmu and it has given me the best battery life out of all the custom roms I have tried. Even with GPS, WIFI, and screen at full brightness I can make it through the entire day with 30-40% battery left. If your looking for a rom-based solution to your battery life, check it out!

Need battery tips for 6+ hrs screen time

Hi guys using wicked with trinity 7b. See a few people posting 2 days on one charge and over 6 hours screen time. Would like to know how as i cannot get anywhere near that. I use system tuner, odex my Rom and kill my tasks whenever possible. I use lh2 modem.
Anyone with huge battery time please help us out here. I'm sure many of us would like some help. Also if you tweak your build.prop press share that.
Looking for details. I'm not a noob
sgs3 : wicked v6 Rom : uv : odexed : trinity

They are not using the stock battery. If you want battery like that, buy an extended battery. That is the only answer.

What I find most telling in many of these screen shots is that Device Idle and Cell Standby are almost always in the top.

Cell standby is actually lying. It was coded with a decimal in the wrong place and so it shows that it uses a lot more than it actually does. Purely cosmetic really, but can be annoying when testing battery issues.
Edit: many custom roms have corrected this btw.

Ya, I saw that before. There is a zip floating around here somewhere that moves it from .34 to 3.4 and fixes it. But you're right that most custom ROMs have this (Cell Standby) fixed.
I just mainly think that Device Idle even being in the top 3 or 4 is a very telling sign that the phone is not being used very much.

Install the easy battery saver app.

I hate to be the jerk... but OP has spammed every rom thread nearly bugging about screen time. Nowadays its hard to get 6+ hours of screen time. Maybe switch to an older, dumber phone with not as sexy as display and you will have better luck. Or carry a spare battery... or strategically place chargers in common spots.

I do all those things (-underclocking and undervolting), and more, because I don't need most of this on all the time, and my screen time is great. Plus, I bought a 4400mah extended battery & get 4-5 days on a single charge.

Then u need an old nokia.

When you plug you phone in the charger the hours reset, my screenshots were to show that its not impossible to get 6+ hours, if I under clock and turn everything off I can probably get that.
The liquid smooth ROM has amazing battery life, you should give it a try I think you will like it.

Screen shots are great guys. I do want to see them. Most importantly trying to see if there are deeper settings and apps to freeze or avoid and tweaks to build.prop etc.
Rom and kernel and modem used would be helpful.
Also, you did charge but the timer will only reset when you fully charge the phone.

WiFi Calling - Efficiency

I was looking at logcat and saw that there is a garbage collection happening almost every second! This happens even if the phone is asleep. If you disable WiFi calling it goes away.
This garbage collecting every second can't be good for the battery.
Does anyone else notice this, can you check?
See screen shot for sample.

I've done extensive testing for overnight power consumption (no use at all) and you save about .2-.3% an hour with wifi calling off with poor signal (my house reception is horrid) and with wifi on. This amount is probably small enough to be considered negligible.

Any graphs from settings > battery to back this up?
My other device has this feature but nice never thought to test it.

Turned off diagnostics how does that affect battery life? And that usage was on 4g just got home and turned on WiFi. GPS is always off. Anything else?

Turning GPS and WIFI off makes no difference. Those draw no power unless they're in use. WIFI only passively looks for a signal when it's on (every 30 seconds and gps is only active if an app uses it. Juice Defender will cause your battery to drain faster too.

My battery life takes a dive when leaving GPS on all the time I don't know if it has something to do with jelly bean or not? It also keeps the phone awake, thus definitely using more battery.

So many devs would like to have a talk with you...
T-Mobile Galaxy S 3, stock and rooted.

Actually the 4G radio uses more battery than wifi. Wifi can turn itself off after inactivity, having apps syncing all the time if you have it on will drain battery immensely. Mainly because it's suppose to be sleeping yet it still running and working and those apps will have a great time doing that. also depends how long you had phone, I have read batteries tend to drain faster after about 5 to 6 months of use.

Ever since Jelly Bean (cm or tw) battery life just isn't what it was on ics I was pulling 20 hour runs with 4 hours of screen time with ics, now I can barely get 9-10 hours with 2 hours of screen time.. It's almost like I'm afraid to use my phone because it'll die.. Very frustrating ik. Hopefully Google addresses this issue in android 4.3 (presumably key lime pie)
Until then, turn off Google Now, and maybe try to pinpoint some random app possibly causing wake locks and not letting the phone sleep properly (with the use of this: http://forum.xda-developers.com/showthread.php?t=1179809 )
