[Q] Which Android fixes overheating?

Do the 4.0.3 ROMS fix the overheating at the top and other battery drain issues? I'm on and been using 4.0.2 ROMS.

I've had it since day one and a bunch of other people have too I just don't know of 0.3 fixes this and the battery drain issues.

Its not so much a fix, as an improvement. Heavy 4g or calls still heat the phone up, but not as bad. remember that there are a lot of fast electronics crammed into a tight space, so its always going to get warm/hot. It seems to come down to better battery use. Its only getting better and better.

data/voice will always heat up your phone. simple as that. i'm just glad that playing games dosn't seem to overheat it.
on my nexus one, if i was playing a kairosoft game my battery got up to 115F+ in no time.

Yeah, when the device is actually being used, its going to heat up no matter what you are doing. But just like a regular PC, it depends on the load of the tasks as well

No overheating problems here. I would hope Samsung has a failsafe and shutdown if it overheats. Otherwise I only get hot when playing a netflix movie over mhl. Amazon movies get warm. Everything is not even a concern.

No I wasn't concerned at all I wanted to know is that in the 4.0.3 roms, was the fact of it getting hot at the top not as bad. The other guy said it got better. Sorry can't quote the name forgot it.

Gnex's Issues !!

Guys , tm not able to understand why gnex's appdrawer and browser lags in landscape mode ??
and here's an archived page
and besides this Galaxy nexus suffers from overheating , grainy and bands on the screen , wifi problems why are there so many issues regarding this device despite of having a dual-core processor and nexus brand name....
Does anybody's else's nexus gets heated up quickly while charging + wifi , lag in landscape ??

Request a replacement sounds like you got a bad egg.

Of course it will heat up if you're using it while plugged in.

Yeah all devices do get heated up while charging but while wifi + charging / flashing ramps up my phone temp to 45C !!
iv'e actually got it imported from USA & here in india we don't have support for nexus.
i'm out of luck , waiting for a workaround or any advices

I'd play with the radio first. If the reception is crap the phone will boost power to the radio, get hotter, and use more battery. Since radios can be very network and region dependent it's worth experimenting.
Since you have no warranty and your phone isn't working right you have nothing to loose by unlocking and flashing a new radio.

My Gnex and my sis's GS2 also heats up to a minimum 40+ degrees.

Damn... Idk what you guys are doing... my battery temp is always 38 degrees celsius and my CPU temp is around 51 degrees celsius and I've never not had my phone feel cool to the touch unless I'm tethering or playing a graphically intensive game.

[Q] T-Mobile S3 - Low Benchmark Scores/Processor not going 100%?

I've had my Galaxy S3 from T-Mobile now for about a week. The phone seems to run perfectly fine. However when I attempt to run Quadrant for example my friends are averaging anywhere from 4900 - 5300 for their stock T-Mobile S3. My same phone, stock, everything closed/killed from task manager, only manages to score 3100 - 3600.
When I check system information in Quadrant sometimes it says my current clock speed is 912Mhz, 1134Mhz etc.. Rarely do I see it at the full 1512Mhz..
Power saving mode is definitely turned off. Even after doing a factory reset and running quadrant on a fresh install it still scores the same. Beginning to get frustrated this phone isn't living up to the hype.
Ideas anyone? Thanks.

I did a battery pull, killed all my apps, cleared my memory, waited a few seconds, ran Quadrant again and still can only manage to score 3100.

No offence but who cares about benchmarks...... the phones soooo smooth and awsome

Sent from my SGH-T999 using xda premium

Don't have mine yet but I have seen someone have the same problem on here and what was wrong with theirs was they didn't know they could set the CPU Max mhz in the settings. Perhaps yours is not set to Max? Not sure where exactly in the settings it is but I'm sure it isn't hard to find
Sent from my SPH-D700 using XDA

I've been through the settings menu in the phone numerous times. Have not seen an option like that nor do I think it exists? For the most part the phone runs smooth I do notice it lags/hangs up sometimes but I'm guessing that's because the processor isn't going to full potential.
Anyone else have any ideas or where I can find this mysterious setting?

I've noticed on my sprint phone that as the phone gets warm the upper limit that the CPU can scale to seems to be reduced. The day I got it the first quad run was about 5k, but after 30min of nonstop usage the next run was down to 3.5 or so. Check it yourself with setcpu, it will start capping at 1100-1200.

I will check it out but considering even after a battery pull and letting the phone sit power off for an hour I still get crappy scores. Then theres others who can run Quadrant back to back to back to back to back and achieve 4500 - 5100 constantly. I can't even get it on one try! I'll download SetCPU and see.

If you are that concerned, wipe and try it all over again.
EDIT - Damn my spotty reading, you already tried that. Sorry. Not much else to do, unless you try to restore the OS through Kies. A fresh install from a fresh source?
Or sell it on craigslist :laugh:

The phone works fine. Everything is very smooth and responds fast. It's pretty much just the benchmark scores that are throwing me off. I'll see what happens with the second S3 I will receive tomorrow. I can't imagine the heat playing a factor because this S4 is supposed to be one of the coolest running processors out there. There's a huge video on it somewhere where they did a butter melting test. Anyways time will tell I suppose.

Why do you care so much about benchmarks? Also the phone won't ramp the processor up to 1500 if it has no reason to..

What's the point of having the newest hottest phone right away? To be able to say it can do what others cant. One of those things being blowing away other phones in the benchmark arena. I just don't see why others are able to hit 5000+ scores and my device can't seem to even come close. It just makes me think there's something wrong with my handset. Do you blame me for being skeptical after the price we pay for these things?

Considering you say it works just fine and are basing these problems that you have off of Quadrant..
Also I guess I will try and help since you are from Chicago they're should definitely be a setting somewhere that allows you to change the CPU settings. I'm not positive where but I did read in a review this was the first phone out of the box able to adjust governors. I would look but I'm on CM9

There is a setting for this, it's actually incorporated in the power savings mode. If you read through it, there is an area that says the max cpu speed is actually lowered when it's enabled. But, if you're not using the power saver mode, then it's irrelevant to your situation. It could have to do with the bloat though, and also the international is almost double the scores as ours yet there is minimal difference in speed presented in side by side real usage testing. I wouldn't get too hung up on the benchmarks, it kind of ruins the enjoyment you get from just using the phone, and seeing how smooth and flawless most everything is. Also, once debated and tweaked, those scores will most definitely improve and will probably ease your mind a bit.

[Q] Is overheating still present in Jelly Bean?

I remember reading somewhere that it was a software not hardware problem so JB could have a fix for it.

I've never had an overheating problem. I also don't recall many having that problem.
Sent from my Galaxy Nexus using xda premium

Overheating? I've never had any of my phones overheat, on GB, ICS or JB.

Are people really having serious overheating (as in phone crashing or shutting down from heat) on a stock device? I have a feeling anyone overheating on ICS is running a custom ROM with voltage changes or overclocks.

My GNex on AOKP and stock voltages does overheat while, for example, playing Modern Combat 3.
Ok maybe overheat is a wrong term a bit since it never crashed or force closed. It just gets fairly hot in the area above camera.
And I'm asking people who did have the problem and upgraded to JB.

My GNex does seem to be running hotter than normal on JB than ICS but not by much. No serious overheating problems at all.

Getting hot and overheating are completely different. The phone gets hot where the battery and processor are, that's just how its going to be, especially when playing 3D games.

No no, my battery stays fairly cool (39 celsius degrees) but the area above camera compared to that is really hot. Way too hot than I think it should be. My previous phone - HD2 was never that hot unless I overclocked it.

Around the camera is where the processor etc. is. The HD2 is also severely less powerful than the Galaxy Nexus.

My cdma nexus doesnt seem to get as hot. I havent really noticed it as much as i did on ICS.

I've been getting overheating since Jelly Bean. Keep in mind that google "improved" things by ramping the CPU up when the screen is touched, even if it's to do a simple task that doesn't require full CPU power... this might exacerbate the overheating issue if you're actively using your device.

Way less then usual. Maybe 50% less. when it does it gets a bit hotter.
So in conclusion I think it's better at this job then ics.

It doesn't ramp it to full clock speed, it ramps it up one step, or two, whatever.
Ramping it up to full speed on every touch would murder the battery.

I've tested it. It ramps one CPU to full clock speed when you move your finger around the screen.
Try it yourself. I wish I could turn that feature off since using Swype has now become an issue...

While on ICS, it'd get up to around 70°C. Now on JB, it usually tops at around somewhere in the 60s°C.

My guide for 18 hours battery life on Jelly Bean

I am here to share my experience to get 18 (around 5-8 hours screen time depend on your usage) hours normal usage, browsing chatting, facebook and calls.
2 days if you are not touching your phone at all, standby.
follow my guide, I think it's all about the Kernel but I shared the rom I used too just in case.
this guide is for GSM, might work on others just download the proper rom and kernel.
Optional, you can underclock to 1ghz but I didn't and got 18 means more if you underclock it.

point 1: when you go to 1GHz , it's called underclocking. undervolting is when you lower the voltage for the corresponding processor frequencies.
point 2: 18h , but what about screen ON ? how much is the "normal usage" equivalent to, in terms of screen ON and the stuff that you're running on your phone.
it's nice to see you trying to contribute and thumbs up for the effort, and i really don't want to sound like an a-hole, but this is not a guide. flashing a custom rom + kernel, and letting the battery go through a few cycles cannot be considered as a guide with battery saving tips. Cheers mate.

You are right, but I learned now ^^
well around 8 hours normal usage of screen time (screen awake), and when I am on a phone call and the screen is off it toke 1% every 10mins
pardon my English

delete this reply cuz I don't find how.

Yah I hate to be that guy but where's the guide? Everyone uses their phone different. You should at least show your battery usage screen shot so we can see screen time etc.

What? Are you telling me that you get 8hrs of screen on time? Is this trolling or just a language barrier?

sorry, I wiped stats but you can study this.
just look at my charge time compared to the times I am using phone, and because it last longer I don't care when its red and low, I was in 5% from 9pm to 11pm chatting from time to time and facebook, and btw my wifi is always on.
and pardon me I am new Xd I am just sharing something not an expert or something but next time I will make sure : it's called underclocking <- I though both are same, and post screenshot and screen on time
EDIT: I think I should charge it to 100% and make it drain then share pics with you guys, that's the proper way for screenshot right Xd? cuz mine looks like a mess XD

Nice XD but I love messing around my phone stock is just... normal XD

Your phone was plugged in multiple times throughout your screenshots. So yes, you should redo screen shots from 100% and include display on time.
It doesn't really matter though, as no one will see your same results unless they use their phone the exact same way.
And under clocking is unnecessary on the nexus, it doesn't spend hardly any time at 1200mhz anyway. I use mine for a lot of game play and still don't spend much time over 691mhz (Trinity kernel). So if my phone decides it does need to ramp up to 1190mhz to remain buttery smooth I'm not going to interfere.

I'm not understanding why you prefer 1.5 trinity kernel and 307 gpu. What benefit are you seeing versus the other trinity kernels with higher gpu and lower overclock limits? Are you running your phone at 1.5?

Same here. I have no problem getting 18 hours out of my stock battery using the stock ROM and kernel, including just shy of 6 hours of screen on time.

I dont know that I would call this a guide. Its saying to use a certain rom and kernel and to charge the phone. . . . .

hey thanks for the write up... i used it alone to change the colors! now my screen isn't yellow.
question though... when I adjust my colors manually, when I go to 0 percent brightness, everything goes like super green... like crazy looking lol.. but at 3 percent it's fine again... any idea why this happens and how I can fix it to get true 0 percent? thanks!
Sent from my Galaxy Nexus using Tapatalk 2

I'm using a stock one and all I can say is: Just dont use Nexus as a videogame.
I got 3 days and some hours of battery talking some minutes and using wifi for some time (probably 4 hours overall).
Playing sucks up the battery life. At least for me.
A normal day of use, with wifi active, many calls, auto bright and SetCPU profiles gives me 'bout 18-24 hours of use.
A intense play day gives me 8 hours. And I think its generous.
