About battery

Hi guys
Does using the device during charging weakens battery
Sent from my GT-S7562 using xda app-developers app

The crucial thing you want to avoid is high temperatures. If you're charging while an app is drawing a lot of current from the battery it may cause the device to become really hot.
But for regular usage as long as the phone stays at normal operating temperatures it shouldn't cause any real damage that would every be noticeable.
Usually if you have your device rooted and have learned about proper rom and kernel setup and kernel configurations you should be able to adjust things to keep temps at a decent level.

Most of the rooted phone will try to run faster with CPU overclocking, so we can't say rooted phone will operate cool.
Best thing is to avoid phone while charging.

Heat issue ,is this normal?

I am running cm9(beast mode wifi calling one ) atm but I have a heat issue with my phone around the camera and speaker area where the phone is really hot but by the battery n bottom half it is much cooler.
is this normal for you guys? N gals? And even if I turn of the phone n it cools to 91 is shoot back up again

idunno why but we have the same problem..
i think that the reason why it heat up is because you overclocking it?
when i set it max it really heat up quickly.

Install betterbatterystats and see how much CPU you are using and on what.

Sometimes I have this problem while charging my phone, it actually will not charge at all through the night. I think this happens when it is warm, because in the summer, the phone overheats in my pocket and dies out

That's a 'feature' of the ICS+ kernels. While 100MHZ is the minimum, if it's actually set to that, the kernel is set to go back to 200MHZ anytime it gets the chance. You can watch this happen if your scheduler/governor app actually updates on current min/max speeds. ROM Toolbox PRO, SetCPU, ROM Control, and CM's Performance controls all display this shifting, though with luck you can sometimes get it to stick at 100MHZ. It just takes some persistence.

The modem on the phone isn't very good.
It even happens on stock where if you go in and out of dead zones, it will "SEARCH" for network and become burning hot, so it's a common problem that happens year round. It's a great way to kill battery. That's also why if you leave you phone in a sock drawer, it's going to last longer than if it's in your pocket walking around.

I never got my phone to go into deep sleep when I selected ondemand (or maybe it was ondemandx). I would try a couple of the other governors & see if that would help.
Sent from my SAMSUNG-SGH-I547 using xda app-developers app

OndemandX gives me good sleep, but forces the phone to minimum speeds when the screen is off. That tends to cause issues if I'm trying to use GPS or music without the screen burning.
As to what will work best... that depends on unique your phone, its apps, any tweaks that have been made, and your specific combination of scheduler/governor settings. I'm a fan of SIO, but sometimes the tweaks make that (and deadline) stick at max MHZ, in which case noop is great. At various times, I go with any of the SA2-based 'intelligent' options (SavagedZen, brazilianwax, SmoothAss, or SmartAssv2) or the OndemandX/Conservative basic sets. The others have gotten stuck more often and tended to allocate more processor than I think it needs.

I've always had the best luck with smartassv2. I think it's a good tradeoff between good battery life and quick processor speedups in order to prevent lag, plus I haven't had the issue of the processor locking up while the screen is off.

That's usually the one I always fall back on too despite new ones all the time and everything, it's my default now on any ROM.

overclocking GPU

Does overclocking the GPU cause damage to the device??ther's a warning of overtemperature when i overclock.Is it safe?

http://www.tomsguide.com/us/overclock-android-device,review-1762-2.html

To answer with something other than a link, potentially. It all depend on the settings and hardware used.
Sent from my LG-LS970 using XDA Premium HD app

Well... it depends of the phone's model. Generally there are not any advice of overheating, the phone simply frezzes or reboots itself.
All overclocking forces to work harder our hardware, so its live will be less (it sufers more wastage and higher temps). Anyway this is not so worrying, cause devices have years of live.

Depends on the hardware so yes and no. For example, the galaxy s1 had a powervr sgx540 clocked at 200mhz. The galaxy nexus had the same GPU but clocked it a bit higher at 384mhz. These companies that manufacture CPUs and GPUs over clock them on purpose to see how high they can push their products before causing them to blow out. They then set their clock speeds far below that max so users don't have to worry about a CPU or GPU frying. Also you must realize that it depends on the cooling as well. So the cooler you keep the higher it can be safely overclocked.
In many cases a device usually would freeze up if problems came up. However, you'd know first since the device would become very hot. If your device has a GPU temp sensor (most have only one for the CPU) then you can probably get an app that tells you you're at a high temp. It is safe if you know what you're doing but overclocking anything has its risk.

Back panel heating

Hello guys,
Guys post your battery temp during normal use,gaming,heavy app use plz..m facing heating issues and want to compare with other Xperia L's

This is during my normal use with 3G which heats upto 40 sometimes

Normal Usage using Wifi

Normal usage with wifi:
After playing around 10 minutes of Asphalt 8 on High settings:
The CPU was at 50 degress but it goes to 48 when I took ss.

I cannot said what the temperature is when I use 3G as my data package is out for this month already, but I think the temperatures provided by you are normal. Like when you are playing Fifa the CPU is cooler than mine. I think they are normal. Most of modern phone's have heating issue during playing.

Well, don't think so. My phone also heats up during charging when I use it. I'm not sure if this work or not but you of course when you wan't can enable option that Nexus 4 has. It's like when a phone reach certain temperature a cpu/gpu clock is lower to prevent battery overheated.
I don't have it enable as mostly I don't play or do anything more stressful that will make phone hot.

dude you have a fit right...oh you sold it, still that device was about half as powerful okay 1/3 rd yet the battery temp with 0 activity and mostly in deep sleep is at 30 C.
now xperia L is way more powerful so should get a tad bit hotter too right(of course that's based on CPU activity) try it put is down for say two hours no charging , no nothing so that in deep sleep(lowest freq) also no 3g(that has its own daemon that eats cpu power i.e. causes cpu to work and hence battery drain and heat). wifi is okay(stable connection hence minimal cpu usage as no reconnections).
now check yor battery temp should be around 35C so your device is fine.
all this is based on stock heat and power management cant comment on custom kernels.

if you are on a custom kernel the best practice is to uv and NOT oc also change the governor to Interactive since thats far better than performance.(spimply put performance goes to top cpu freq even when not required and slowly scales down while interactive scales up fast and down fast at user touch events) for heating and basic phone wear and tear purposes.
and one of the main reason along with more ram(i mean lower bloat hence more free ram) that i want a cyanogen mod ROM.

Before and after playing candy crush.lol
When charging,it will up to 37-39 degrees

Qualcomm makes the MSM8230 chip that you see in L, there are 4 different "types" based on how it meets their quality standards. These are Slow, Nominal and Fast (Faster is on Higher end chips like APQ8064). The main difference IIRC between these types is how stable each can handle undervolting. CPUs that are "Fast" for example come pre-configured at a lower nominal voltage than a "Nominal" type CPU, and more so than a "Slow" type. IIRC, there's like only a -50mV difference between Fast and Slow out of the box, however Fast CPUs should be able to handle lower voltages than Slow-type.
This may explain why some people complain higher temp than others on account of same tasks. Although there can be other reasons. I'm not quite sure.
To find out what binned CPU you have, I recommend the following:
YOU MUST BE ROOTED! And installed busybox
1) Install Terminal Emulator
2) Reboot your phone
3) Open Terminal Emulator, and type:
su
dmesg | grep PVS
(if you don't see anything, try it.immediately after fresh reboot)
For example I've fast binned cpu

So basically, far as I understand I got Fast CPU which isn't going to be as hot as the Slow type due to lower voltage ?

then go for ondemand the performance might be a tad bit slower than preformance governor but your battery life should be better along with the heating...also no oc.

Note 3 N900 4.4.2 heating and lagging discussion

Hello everybody,
I opened this thread so anyone experiencing this problem (overheating and lagging in heavy games such as: Real Racing 3, The Amazing Spiderman 2, even Candy Crush, Asphalt 8 and so on) can discuss it here and maybe we'll get a better perspective of the problem, and maybe find a solution for that.
The Problem :
The phone would heat up, sometimes to the point I can't touch the phone, and the game FPS drops significantly (the games start to lag).
It happens for me after about 5-8 min of gameplay.
From a little google search, some users reported that the problem was caused by the constant running of the IndexService(this process is responsible for Indexing files both on the internal and external sd card) process, some users formatted the sdcard and reported that it has stopped, some users reported that the problem is still there, some users replaced the sdcard with another.
For me, I'm still trying to figure out if the sdcard is the problem by running some monitoring apps like System Panel Pro, and waiting for tomorrow to see which process/apps uses the CPU more than the others.
For anyone commenting this post, I would like you to ask to state if you are on a stock or custom rom, as well as the kernel.
Hopefully, we can identify the cause and help the Note 3 community and finally enjoy the full power of our AWESOME phone.
Happy discussion!

up

From my own experience, the cpu clock and the brightness of the screen has most to do with overheating. I have the same problem on a rootex X-note v13 (and all other xnote versions before 13), the cpu temp would reach 60 degrees celsius after 5-10 ninutes of gameplay on max brightness and stock cpu clock. BUT if I were to lower brightness to minimum and lower the cpu clock to 1.7ghz (left it at 1.7ghz since then out of laziness), it would last at least 25 minutes before reaching the same temperatures. Still, I would be curious if there is any software trigger that creates this overheat, not just the cpu and brightness. I had my phone unrooted for a very short period of time so i cannot really say, but it did feel like stock unrooted did not overheat so fast. Or maybe it was just a placebo, I do not know

Not sure what could cause that problem but i cant confirm that i dont have the problem, i usualy play RR3 and Clash of clans for long periods of time, 2+ hours and my phone wont heat up at all. i do have the lastest RU official firmaware do, but even with the other ones i never got that problem, i use to hate my s4 for that but i cant be happy enoght with my note 3.

I will be sending the device for repairment to see what the problem is, and will report back here
Maybe there is a problem with some Exynos devices ...
Will be interesting to find out what's the cause for the problem with our high-end phone.

Update: installing other ROM + Factory reset in that ROM gave the exact same effect: overheating.

Disabling DVFS completely fixed this issue for me.
Either use the DVFS diabler app or Wanam exposed to do this.
FYI I have the n9005 so this may not work for you.

I think everyone has the hot screen issue but for me it seems to happen in certain games only.
This isn't limited to 4.4.2 either, it happened in 4.3. It really seems to point to a software issue rather than hardware.
The weird thing is its the upper portion that gets hot on my phone while the battery portion is just normal.
I have temperature software on mine and for what it's worth I've never had a warning about overheating yet.

Disabling DVFS does not Solve the problem unfortunately...
The heating is where the cpu is...
It gets to the point I can't touch my phone...
I've tried different games and it kinda happens in every single heavy games... It is very annoying that I have such a powerful phone and I can't fully use it as I please...
Will try to send it to Samsung and see what they will do...

I managed to solve the problem !
Opting out google's location based ads in Google settings , disabling Samsung DVFS , formatting the phone and SD Card (with data included), installing a custom Rom (Dr.ketan K7 ROM with some options from the AROMA installation) ,
All that has managed to solve the problem .
Now the phone just get warm , as I think it should be for such a thin and powerful device.
I hope that now everyone that have the problem can solve it and enjoy his awesome phone!
Have a great day guys!

If you have SD card, it might be causing heat and lag issues, so try to remove it then try phone, if yes then format it, if its not the cause then perhaps you have an app causing problem, so do full wipe from recovery mode, after that try phone for couple of days without downloading any app.

The problem was DVFS. SD has nothing to do with battery drain

The temp seems about right.
My phone got up to 80C when I tried to play it once for more than 10 min and then it just did a reboot...
Within the Android OS and Android System services there are a lot of processes going on... You should try and pin point the exact process that causes Android OS and Android System to be active.
I'm here if you need anything else!
