Meaning, does the battery life take a dip when you overclock to 1.5ghz. Does it get any hotter? Is heat an issue at all on this thing? Also, any performance or battery changes from installing the tiamet kernel itself? I'm in the wifi xoom btw.
Strangely enough battery life seems to be about the same. Heat has not been an issue mainly due to having the dual core, however its something you always want to keep an eye on.
Battery life is affected most by the screen. Screen> Network connections > CPU > RAM
There was a thread that someone made a while back about the things that affected battery life the most. If I can find It ill send it your way. After seeing the charts I figured Id try changing some settings.
things I did:
1. Set my max cpu freq to 1.19 min to 488 same for all my cpu tunner profiles ( I wanted to have my phone running the same all the time)
2. Lower'd my screen settings. I didnt need a pocket flashlight EVERYTIME I unlocked my phone.
3. Turned off un needed network connections. Its not hard to turn them back on when you need them.
4. I then looked for things that were running but were not needed by anything ( google maps are used by a few apps so dont disable it haha) I used Uninstaller for root users to get rid of some things.
After all these steps my battery life went WAY up. I have been doing the same thing on my Xoom now and my batt lasts the same at 1.5 as it did at 1.
I still get VERY respectable battery life at 1.5ghz, I can easily get through the day with normal usage. Yesterday night in fact, I left the house with maybe 75% battery life, used my tablet quite a lot throughout the evening(left the house around 9, went to sleep around 1am) and used it all morning basically constantly from 7am to around noon and came home with 9% battery left.
No problems here either. Woke up around 8:30 yesterday and used it all day sometimes pretty heavy. Finally had to plug it in around 6:30. I'm home all day with a broken hip and femur, so I've been putting it through the paces. Running @ 1.5ghz with interactive gov.

+1 on 1.5GHz having little effect on battery life. I didn't have to change anything else, either.
thats all great to hear! I suppose ill start looking into rooting my wifi xoom tomorrow then. Thanks for the help!
Im very happy with the battery life on this thing. I expected 4 hours max after a few weeks of use/charges. I never thought that it would keep up with anything Apple, Lets face it.. Apple knows how to make stuff run forever. But I was plesently suprised. Xoom +1000
yeah, the battery is good, but i won't know any damage to the cpu when overclocked ?
I wouldn't worry about any CPU damage- too many people have reported success (and no reports of failure).
Anyone else notice with the tiamat kernel that their xoom becomes very unstable overclocked at 1.5 using setCPU? Mine was essentially a soft brick at 1.5 constant rebooting and never able get pass the unlock screen, I had to rewipe with bootloader. I can do 1.2 no problem but don't even want to try going higher.
All of our chips have variations, so the overclock isn't universally guaranteed. That being said, I've been using the Tiamat kernel @1.5GHz since it was released with no problems.
Should have stated that mine is the wifi model, but yea thanks for info.
Here was that post I was looking for on this stuff. http://forum.xda-developers.com/forumdisplay.php?f=946
Hi all,
I have been using the ONDEMAND CPU governor for quite a while on my SGS4G running CM9 (Team Acid's version, the final herring one), and I have just gotten used to the 12-14 hour battery life that I have had ever since I switched from GB back in August 2012. However, most of the frequent users here recommend the SMARTASSV2 governor, so I tried to use that yesterday to see if battery life was enhanced.
If anything it seems that my battery life got worse (see attached picture). I am a moderate phone user in general; I use my phone for texting mostly, and sometimes I'll look something up on the Internet, but no music, WiFi and GPS are always turned off, no overclocking/undervolting. I recently purchased a new battery as my old one died about two months ago.
I was wondering, is there any governor for the CM9 ROM that is particularly good with battery but doesn't completely drain performance?
(Also, I tried to use the LZ kernel before, but it seemed to cause many more problems than it fixed.)
You've got some pretty bad wakelocks going on there. See how your phone is awake even though your screen is off? That is an issue. Also how much screen on time did you have on that run? Get Better Battery Stats(free on XDA) then fully charge and look at what wakelocks are occurring. You might also want to consider UVing if you want better battery life.
Also, if you're a fan of ondemand, I highly suggest moving to ondemandX, which actually does deep sleep when the phone is off.
But that will only help if you fix the wakelocks first. So follow hechoen's advice and your phone should be way more awesome.
Downloaded BBS today, we'll see how it goes.

Hey all,
As of about a month ago, my beloved Nexus 5 has been getting extremely hot to the touch. As a result of that, the device is uncomfortable to handle and is dying quite quickly. As this was a factory refurbished I got from eBay, I had no warranty on it. I read a thread on here awhile ago that Thermal Paste could help with heat on the CPU, so I decided to try that as I didn't have a warranty to void. That did help with the temperature on the CPU, but because Thermal Paste is a conductor, all the heat dissipated into the screen, essentially making the screen a mini stove. I then heard that Thermal Pads might work better, so I ordered some off of Amazon and applied them to my CPU. This helped with idle temperatures, but as soon as I touched the screen they raised back up again. I've tried everything, CyanogenMod 12.1, CyanogenMod 13, CAF ROMs, and I even flashed it back to stock. Nothing works.
Now for the odd thing: Idle Temperatures are normal, at around 38°C. Load Temperatures are fine, it reaches around 65°C under AnTuTu's Stress Test. However, under normal use such as browsing Chrome or watching YouTube, the Temperature IMMEDIATELY goes from Idle up to about 58 °C, and stays there. The phone loses battery rapidly, and it burns my hand using it. I've checked for CPU hogging apps, there were none. I made sure I was on the correct CPU Governor, and I was. Even on the Conservative Governor the Temperature was still going up to 58° C.
I have no idea what is going on. I might have an idea, but I don't know if it's even how the phone would work. My battery has been acting up lately, even before the phone started heating up. Some of the times when I've taken the phone apart, I noticed that the Battery's Ribbon Cable sparked a bit. With this and the fact the the battery has been acting up, it leads me to believe the the battery might be unstable. Could the battery be delivering too much power/voltage to the CPU, causing it to heat up? Just a wild guess
Help would be extremely appreciated
its battery issue. try changing it
OK, I ran into this issue about 5 days ago. No matter what ROM I install, my phone constantly heats up within 15-20 mins of casual usage. I don't even play games on my phone. I tried N ROMs and MM ROMs too, no matter what ROM I install, phone just heats up. I'm attaching a screenshot from CPU-Z app (which I used to monitor the temperature). Are those readings OK, or is there something wrong with my phone?
My phone's temperatures are usually similar to yours and I thought this was normal. In case it's not I'd like to see a solution to this as well.
Btw, do you have any custom kernels? Agni made my phone way too hot..

I don't really go for custom kernels unless I'm testing one. I stick to the kernel that comes with the ROM.
Check kernel adiutor if your frequenties are peaking constantly

I have checked. They are mostly around 800 MHz mark. And 45% of the time in deep sleep or 400 MHz.
Also I want to whether surrounding temperature can affect the values? Right now the temperature at my home city is averaging around 34-35°C. Would that be the cause?

Not to hijack the thread but I have experienced all the cores being on max. frequency. I noticed this when my phone started warming up even being idle.
I saw this behavior for a few times in RR with both Optimus and Firekernel (Optimus had optimus set as its governor and Firekernel had darkness), however never encountered it in Ultradevs (with both chill and darkness).
This was a couple of months ago, and it hasn't happened again yet. However I am not sure if this was related to kernel because sometimes force stopping random applications such as greenify or nova launcher made the frequency scale down back to 400 (efficiency profile). Unfortunately I didn't get a hold on what was causing this, but I suspect some background user application was the culprit.

I also faced this issue first time when I flashed RR 5.8.2, no custom kernel used. And now its following on every ROM I install. I even tried custom kernels, different gapps packages but none seem to work. The phone heats up while charging and while doing simple things like using WhatsApp, sending emails, browsing through XDA. Also kernel adiutor is showing that GPU temperature is always above 43°C.

Did you restore apps through some backup program such as Titanium backup? In my case, I used to use it and it might be the reason the problem was popping up everywhere.
If not, and if the phone still heats up even in clean state (after a fresh custom/stock rom install), then maybe some hardware issue could be the reason.
My Cpu-z reports battery being at 37° discharging and the sensor0 to sensor5 show 45-51°c although the phone feels way cooler than that.

I clean installed all the ROMs. Still the issue persists. I haven't tried stock ROM yet. I'll try that and report back.

yeah, thinking you may have to flash stock, not restore it via twrp. I know it's a pain but it would give you a good reference point.
Well I can't flash stock ROM for the next 2 days. So let me ask this : Is a temperature of 37-42°C for battery and CPU harmful for the phone? Or I shouldn't worry about it?
107F? I shouldn't think so...
"Right now the temperature at my home city is averaging around 34-35°C. Would that be the cause? " It wouldn't help...
I am 26 ambient and my phone temps run 36-36 or so.
Ambient temp does play a factor. If the phone is Almost as hot as the ambient it's hard to transfer the phone heat to the ambient surrounding.
My freqs and temps in attachment. I use aosp-caf with prepackaged kernel(ud i think) with some custom settings.
Ambient temp is around 20 C inside and 10 C outside

Thanks a lot. Even when my phone was not heating up, the CPU and battery never got cooler 31°C. And GPU was around 38°C. And even after intensive use, CPU never got hotter than 37°C.
Now my phone's CPU and battery are around 35°C mark and GPU around 43°C. And during use CPU reaches 43°C mark and GPU about 52°C. Can these temperatures cause any harm to the device?

Don't quote me but I think it's okay. Motorola should have tested it on much higher temps. So just go with it if it dies you maybe have warranty.

I had the same issue . with few ROMS . My device temperature went around 70C on oen ROM. I am usimng Osprey 1GB RAM
I have not faced any issues since I am using Nano Gapps. Previousely I used Mini gapps and that was causing the issue . Depend whar Mobile you use 1GB RAM or 2GB RAM. Also it is better to clear cache after every install
Also I use following settings to make suer it doe snot get hot.
-Ambient Display Off
-Adaptive Display Off
-Try not to block any apps from sending notoification as I had issues where battery draining and mobiel heating up by doing so
-Keep brightness to minimum
and since I am using this I had not any issues with heating

Thanks for replying but its not the issue of any ROM. I flashed stock and the issue still persisted. So I literally contacted everyone I know of who owns an unrooted osprey in my city and asked them about this.
Turns out everyone's phone is getting hotter a lot faster than before. Even went into a Moto Service Centre, they said its fine for the phone to heat up in such temperatures.
The issue is ambient heat. As you might have seen in my previous post, I mentioned that the temperature in my city is averaging around 35-36°C (Today it reached 40°C), the phone just doesn't cool down enough after using it. So when I started to use it again, it heated up.
Thanks everyone for replying.

That's what I figured. Thanks.
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.
