Starting a month and half ago my LG Nexus 5 would get hot near the camera (Where the CPU is) and drain the battery unusually fast, even without an active app opened, now I can not keep it on outside because of the drain and even if it stays connected to a charger, it slowly builds a charge because of the drain.
I recently changed the battery and the problem continues to persist.
This started happening around when I went over all the settings in the phone and apps, I fear I might of turned on something that is causing it in the background but I can not figure out the exact problem.
Please help.

Check the frequencies of the cpu, sometimes the minimum value gets stuck to a higher than needed frequency.
You can do so by using Kernel Auditor (root) or CPU-Z. Obviously if they're higher you'll need to set them lower, 300 MHz is the normal minimum freq. If that is not the case then install Gsam Battery Monitor and enable extra stats, you should be able to figure something out with that one app.

So I just got a brand new D2G and thanks to the info in this forum I rooted it and installed fission rom and FRM...Im loving the phone, its fast, smooth and beautiful but the battery is AWFUL. I have read all the info about how to get the most out of your battery and everything on these forums but mine is waaaay worse than anyone has said before.
For instance, last night my phone was charging oernight, at 6 am when i woke up to pee it was at 100% so I unplugged it and went back to sleep, come 10 am when i woke up my phone was down to 15%!!! From just sitting there with the screen off...
Ive set the network to CDMA/Evduo automatic, installed Jrummy's overclock app...Can anyone explain in detail what exactly the settings in the overclock app mean? "set scaling frequencies at boot, cpu scaling frequencies etc?" for instance if I set scaling frequencies not at boot to ultra low voltage and 1 ghz and lower, do i need to also go into cpu scaling frequencies and make profiles and stuff?
Any information is greatly appreciated, Ive been reading up for days but this stuff is hard to find clear answers on specific issues. Thanks!
This is probably the most basic first thing to ask/do, but have you checked the battery useage to see which apps are using the most power? try doing what you did where you charged, and then let it sit for 4 hrs, and after that see what's using the battery, I bet there is some app that just nonstop uses the gps or 3g data or something wearing your battery life out super fast.
Yeah i looked at that this morning to see and all it said was suspend took up like 90% of the battery...Doesnt make any sense
1. Set at boot isn't what you're thinking. Set at boot means that whatever your current settings are will be set the NEXT time the phone boots. This is used when you have a setting you like. The reason you DON'T want to set at boot is that if you accidentally pick a setting that your phone doesn't like, and it makes it crash, then next time it will boot up with normal settings. Otherwise, you'd be looking at some work doing a recovery with either CWR or RSDLite... There are better ways to spend 30 minutes. Disclaimer: I use SetCPU, but the settings are all essentially the same.
2. For scaling, unless you're a power user (read: Geek) who's really up on his stuff, you should just stick with ondemand. This means your CPU will run at the lowest frequency possible, but will scale its speed up when processes call for it. This is efficient.
3. Yes, you should still make profiles. The setting on the main screen where you choose "Set at Boot" (Again, I'm speaking from SetCPU experience, but it SHOULD be the same) is just the main profile, setting the global minimum and maximum. You should leave the minimum on this at 300. The phones don't like to run much lower than that, even with the screen off; They start not ringing for calls, not waking up, etc. Set the maximum to whatever you want the max to be. You can overclock, which will obviously hurt your battery life. You could underclock and set the maximum to 1GHz, or even 800MHz, which would have a decent effect on battery life with no noticeable performance decrease to the average user. I run mine at the stock 1.2GHz and it's fast enough for my needs.
4. I wrote this thread to help people maximize their battery life. It's pretty detailed, you should give it a thorough read, it works well for me, and seems to work for others. I'm at 32hrs unplugged and my battery has gone from 90% to 20%. That's pretty light use, and I have an extended battery, but I still see over a day on my stock battery when I use it. There's a list of my SetCPU profiles there too, that might be helpful in setting up your own.
Thanks for the info on overclocking, I think I have it figured out now...
I will definitely read through your thread, but is it possible that I just had a bad battery? due to a shipping error, when verizon sent me my phone they sent 2 by accident so I just swapped out the battery for the other one and it seems to be doing much better already...
This is what I've done to help my battery life.
Firstly you'll have to root your device, then follow the steps below.
1. Install SetCPU(from Market or where ever you can find it)
2. Run it, allowing root access when asked by superuser.
3. On the Main tab, set Max and Min to 1200000(1.2Ghz), or whatever you want general usage to be. Most users probably want it like this so it will stay at best performance during using, and will not slow down. Also, whatever speed you're using set Scaling to Performance. Even if you are not running at top speed, it is still good to use Performance for the settings you want while using the device.
4. Go to Profiles tab. and check Enable, and click Add Profile. Set it to Screen Off, and you can change the settings to whatever you want. I had it at 100000(.1Ghz) for Min and Max, but when you go to unlock your screen, it lags a lot for a second. I currently have Max and Min set to 400000(.4GHz), and it made it so it does not lag when I go to unlock, but it is still low enough to be very conservative on battery. Set Scaling to Powersave, and Priority does not matter unless you have more than one profile, so don't worry about it.
5. (Optional) Install JuicePlotter from the Market, for free, and it has a nice widget that collects your phone data and after a few days will become very accurate on phone battery life remaining. It will show it after a day or so, but it will tell you how accurate it is, and it might not be very high until a few days later.
And that's it. Whenever your screen is off, it will underclock the processor so it's not using as much battery when not necessary. If you want, you can add other profiles, such as for when charging, and when the battery is low. I originally had it set to 1.2 GHz Max and Min while charging, and set the priority higher than the Screen Off, so it didn't clock down if I turned the screen off while charging, but there is no reason, I'm still not using it when I turn off the screen, so I deleted that profile.
So if your only profile is the Screen Off, then once you turn the screen on, it will change to whatever settings you have on the Main tab.
I unplugged my phone at 6:30 AM, and it is now 5:30 PM here, and I still have 32% battery, with JuicePlotter telling me I have 4 hours and 49 min left, but it only has a 72% accuracy since I just got the app yesterday. That's great since yesterday my phone would have been dead over 2 hours ago. When I woke up JuicePlotter said I had around 15 hours, but it wasn't as accurate as it is now, and it so far is expected to last longer than that..
I just use JuiceDefender free set to Agressive to obtain the best battery life. I got this little vendetta against SetCPU though.

It takes you to a recommended battery saving app from the market. I haven't tried that app, but I imagine it is probably something similar to SetCPU.
I think this is wholly unnecessary, I'm sure samsung underclocks when not in use already, it's an obvious thing to do. I haven't done any of this and I can get ~40 hours of light-medium use
But try watching justin.tv streaming movie on hspa+ lets see if you even get 4hrs?

After reading a lot of battery drain threads on this Samsung Galaxy I9003 subforum i have a doubt:
The recommended solution is to install a clean android 2.3.4 rom?
In my case the phone came with froyo and after a couple of months i decide to upgrade up to 2.3.5... anyway, about one week the phone starts to constantly heat up on stand by mode without 3g or wifi activated and off course the battery starts to drain :S on battery stats i can see the bigger consume (about 62%) is related to stand by mode :S
I try :
battery calibration
factory reset
wipe
reflash 2.3.5
flash 2.3.6
But sadly the problem persist :S
Todayi installed CPU spy and i got a big surprise when i saw the stats of CPU speed, most of the time turns to 1000mhz , like i said the phone it's ond stand by mode with no 3g, wifi connections activated :S
Also i rooted the phone and installed setCPU to limit the max speed up to 300mhz, with that i can see the phone doesnt heat that much (compared when it runs at constantly 1000mhz) but still works at constant 300mhz whatever i do...
I really hope that the solution is to reflash 2.3.4 (or maybe lower?) firmware
Thanks for share all your knowledge and help people like me
If that the case then its an APP. You surely have an app that avoids your phone to go to sleep.
Thanks for your attention and time, i hav running setCPU (at barely 300mhz) and now the CPU temp is always at 32°C also i installed Watchdog lite and doesnt show any program doing an excesive CPU usage :S
Really i have no more ideas of what to look at
Yesterday at night i was reading a lot of drain battery related post (all the threads i found basically) and do the following:
Enter to CWM recovery menu > Advanced > Wipe dalvik
Also i select the ondemand settings for setCPU
Now the phone it's all the time on stable 36°C but sadly my battery still is drained (probably on deep sleep) Most of the time the processor is only at 300mhz and looking the battery stats android system and screen use an average precent (42% for display 23% for android system)
From a full charge (over a powered off phone) after 4 hours the battery has only 40% of ramaining charge and the phone it's on deep sleep (this phone today it's used only for make and receive calls, so no internet connection is activated)
No other people are facing this issue?
My HOX running on 4.2.2 Sense 5 stock rom is having heat issues i believe i dont know if its normal
PS default Kernel (still cant get Beastmode,god knows why)
i use "ondemand" as my governor and "noop" as my scheduler with set cpu
i also have trickster mod installed but i use it only for monitoring temp and on what frequency is the cpu running!
when its idle temp is temp of cpu is 35 degrees Celsius and battery 26 degrees Celsius
whenever I am using my phone for internet for benchmarks etc CPU is 40 degrees Celsius and battery is at around 32 degrees Celsius
the phone feels ok
but whenever i start any game no matter how simple it maybe (this applies for a wide spectrum of games ranging from * ball pool to demanding games like Asphalt 8) i notice my backside especially region around my camera getting warmer (now its not very hot but you can tell the difference)
at that time the reading shown is CPU is 45 degrees Celsius and battery becomes 36 degrees Celsius
PS the phone never restarts the game doesn't crash it runs smoothly
is it normal!?
i have read on web that lithium polymer batteries should be kept below 35 degrees Celsius for optimum life and performance
i dot have any background apps running whem i am gaming and the rise is observed in a few minutes or so i usually play a game for max 15 mins after that everything cools down!
this rise is also observed during taking back up through Twrp!
Those temps seem totally normal. Yes, higher temperatures are stressful to Li ion batteries, and hasten capacity loss. But to some extent, you need to try not to worry about it, and enjoy the phone for what it is.
While I don't game much, I do notice the phone getting warm while using Navigation, Netflix, etc. I've had my EVITA since just after release in May 2012, and I haven't noticed any loss in battery life.

you know the device very well and since u says its normal m glad
thanks u saved me i was thinking of what not like under volting and all those tweaks with the kernel!
Btw redpoint is i know the nature of ondemand governor but in my case it is either the max or min frequency it operates,so is it a good idea to switch over to powersave?
(and does our kernel support that)

Haven't used SetCPU in a while, but pretty sure if the option appears in SetCPU, its supported by the kernel. Depending on what kernel you have installed, more or less governor options will be visible.
Governor seems like a trial and error type of choice. It depends on how you use your phone, and not everyone will get the same results.

66° Celsius. seriously and that too the battery?
like is this normal?
besides the phone doesn't restart or get damaged?
Yep, 66° battery temp. That isn't a normal operating temperature though, that was while my phone was rendering a huge picsphere image from the Focal camera.
There are safeguards in place in case the phone does reach a temperature that would damage the phone. The phone will first warn you it's getting hot by flashing the led red and green, if it continues to heat up it will shut down.

Hello. I'm new with the account here, but been reading this forum for years.
I'm creating this thread because my new Nexus 5 (which I have for 20 days now) is overheating more than a normal mobile device should.
When i bought it, it had 4.4.4 Kit kat android, and I had that one for about 5 days, and in that time, I didn't notice any overheating, or maybe didn't pay attention, can't remember really.
But after installing official Lollipop 5.0.1, the device is heating pretty good even when browsing internet for 5 minutes, at about 30-40% brightness.
**** Please tell me if some of your devices are acting the same, and is it worth a try to install back an older android to try if it will stop overheating, or my device may be faulty and should I take it back for another one (or maybe switch to LG G2) ?
Because I'm still unable to post image links, i will write it down:
- Ambient temperature: 23 degrees Celsius
- The temperature sensor is taped on the back side, at the side of camera, this is where it overheats most. (even if not using camera)
- Phone temp after staying on standby with screen off: 28 C (it's not warm but it is warmer than desk which it is sitting on)
- After staying idle on home screen with screen on for 10 minutes (50% brightness): 30.5 C
- After chatting on Messenger for 10 minutes: 34.3 C (feels warm)
- After recording video for 4 minutes: 41 Celsius!!! (almost uncomfortably hot in the whole upper half of the phone, both the back side and the screen)
- After 15 minutes letting it cool down, with screen off of course, it is 38 C (still hot to touch), and it stays like that untill I reboot the phone, then it cools down.
The test took about 50 minutes, and after that, battery was drained for about 25%.
-While charging, the phone does not overheat, just gets a little warm which is OK. (haven't tried wireless charging)
P.S. I don't play games on the phone...
Please act quick in case I should return the phone...
the only time my phone gets hot is when im intensively doing a lot of things..
for example.. im playing ingress, have tether ON, and my two sons are using their tablets connected to my phone playing ingress too..
but if i turn off the game and turn off tether, it cools down..
to me it sounds u have something intesively using your CPU and perhaps GPS and other radios.
hold power button.. when PWR OFF shows, long press it and reboot into SAFE MODE...
use the phone for a bit and see if it gets warm... this should tell you if its apps installed.
I only used wifi, no tethering, no GPS, 3G, NFC or any other radios, cell signal is good so phone is not searching for it.
- In safe mode, it still gets warm when using camera. When browsing internet and watching images in google search, also but just mild warm..
- But after sitting and thinking, I've found a problem! After recording with camera and leaving it to cool down, it didn't cool down because it had to make an effort to upload that 5 min video on Google drive via Auto backup!
After turning the Auto-backup off, it is now much cooler!
I will post tomorrow with the results, if something changes...
Anyway, thank you!
First of all, "warm" doesn't mean anything.
Battery temperature does not mean much either, as the CPU is what generates the most heat.
There is a battery temperature throttle that reduces the CPU frequency, but it is almost entirely pointless as the CPU will always reach it's own throttle temperatures MUCH, MUCH earlier than the battery will. The CPU starts throttling at 65C CPU temp (NOT battery temp), and shuts itself down at about 105C CPU temp. Unless your battery somehow reaches a batterytemp of 70C+ (nearly impossible because the CPU will always hit it's throttle first), then I would never even take it into any sort of consideration unless you have a physical battery defect.
Using the camera generates heat since it's CPU and power intensive.
Using the phone in general will generate heat.
Keep in mind that mobile devices are passively cooled, not actively cooled with a fan/liquid.
Not sure what you're so worried about.
Lower your brightness
Lethargy, thank you for a short physics lesson. I'm already into physics and cooling systems so all is clear. I was just worried a bit because all of my previous phones weren't getting this warm (hot), but also never had a multi-core processor in phone eather, maybe that's the reason why I never experienced this before.
Battery temp (measured with app) gets up to 40-42 degrees Celsius, while the phone case gets up to 41 when recording video. Of course that temp won't damage the device, I'm not worried about the processor, but that temp is degrading battery life, in long term.
And about the brightness, phone is not meant to be used at lowest brightness all the time, so that shouldn't be an excuse for high temps. Just sayin'...

The only thing that sounded odd was how it wasn't cooling down until you rebooted, but it sounds like you figured that out with the automatic upload setting.
41-42c battery temp can be normal after prolonged usage, though personally I usually see that after a short gaming session. My brightness is around 40% and high brightness will cause extra heat.
Otherwise the phone is very thin so you can feel the stacked SoC and RAM heat up through the skin fairly easily, right around the camera area as you mentioned.
I think each device and CPU is slightly different and can vary by a few degrees under load as well.

Your temperatures are fine and you shouldn't worry about it. It's average for a Nexus 5, and there are throttles/shutdown temps anyways, for both the battery and CPU. I've had mine for a year and there hasn't been any sort of issue, normal usage should be negligible to the condition of the battery.
Ok, everything seems to be ok then. Now I can go to sleep without worrying Thanks guys!
