[Q] XT1527 pure stock - excessive CPU? - E 2015 Q&A, Help & Troubleshooting

Just picked up an XT1527 (full package, box, accessories, everything) from a craigslist seller for $40 - I figured it would give me something to play with until Motorola ships my "free" Moto X (32GB 2013 model) as a replacement exchange for my old Atrix HD which bricked when I installed the last update for it. For the record, this is the Cricket model.
Upon playing around with it for the past few hours, however, I've noted it tends to run just a bit warm even when I'm not really doing much of anything so I started checking into it - I'm still pure stock, mind you, 5.0.2 build LXI22.50-13.4) and I'm thinking about rooting it and perhaps checking out the CM12.1 build but there's no hurry at the moment.
Having said all that, I grabbed CPU-Z and took a peek at the SoC specs: it shows an idle speed of 800 MHz for all four of the cores even in spite of them having a 200 to 1.2 GHz range. One would think that the device would ramp down to 200 MHz when idle and not doing much of anything at all but, that's not the case so far.
So I grabbed System Monitor Lite to check just in case CPU-Z was reading things incorrectly and got the same exact results. Upon checking the pie graph it clearly shows a range of 800 MHz to 1.2 GHz and nothing below it.
Has anyone else noted this issue with the Moto E 2015 model or... am I just so new with this thing (having owned oh, maybe 200 other devices in the past decade and doing some rather intensive customizations on 'em) that I'm missing something here and just not even noticing it?
Had hoped to keep this device relatively clean and stock but, it appears that's not practical if this CPU speed situation can't be resolved. I see there's basically only the one custom kernel available so far (Squid) and while I'm not opposed to using it once rooted/etc I'm still curious as to know why this thing isn't ramping down the clock as it should. It's using the default interactive governor as well, would be nice to be able to alter that but again that's where it gets more complicated.
Anyone else noted this on their XT1527 (or any of them, really, just as long as it's a 2015 model) or would someone else that's running pure stock be willing to check their CPU usage with CPU-Z or System Monitor or something else and see if it's not ramping down below 800 MHz as it actually should? Obviously the battery life would dramatically improve if this thing would slow down as it should - there could be some new Qualcomm trickery at work here that I'm not aware of, but if it's capable of dropping back to 200 MHz, it damned well better.
Any comments and suggestions are appreciated...
ps
Also I've noted the GPU doesn't ramp down to 200 MHz as it should either, it hovers at 310 MHz almost constantly which again is just another waste of battery when staring at a static image on the screen (save for the info updates themselves but that's not really a thing that should or would trigger a big spike in GPU speed).

o.o thank you so much. You'd wonder why. Well, yesterday (I think) I made a topic about how my phone drains battery abnormally and I just checked with the app you said (cpu-z) and it seems I have the same problem. My phone feels warm almost all the time and it also keeps working up to 800 MHz in all cores. Also, I own the same model and someone in the other topic told me that battery should last 2 or 3 days without doing something. Oh anyway, thanks because now I have a hint about what's going on. Maybe its a manufacturer problem.

For some reason, Motorola set the CPU idle speed to 800 MHz. I don't know why. I lowered the idle speed to 400 MHz on my phone, and I'm not noticing any performance degradation. I haven't noticed any heat or battery issues though. My phone stays fairly cool, even under heavy load (like running benchmarks repeatedly). I've undervolted my phone slightly, that may reduce heat a bit, though I don't recall having any heat issues without the undervolt either.

Well squid, I'm guessing you are using a pretty customized setup at the moment including the kernel you've created so, I'll most likely end up getting a similar situation I suppose. Since the Snapdragon 410 can do 200 MHz to 1.2 GHz it damned well better do it; if Motorola for some reason chose to "hard lock" it at an 800 MHz idle speed that's a bit ridiculous and will only serve to hamper battery life overall.
Performance isn't the issue here since as soon as some CPU power is required it'll ramp up as expected - the issue here is the 800 MHz "bottom" which should actually be 200 MHz. That's a big difference in terms of overall battery life in the long run.
I owned an LG Tribute in late 2014 and was regularly getting 8+ hours of SOT with that which is powered by a Snapdragon 400 (1.2 GHz quad core) and that has a 2100 mAh hour battery - the Snapdragon 410 in this Moto E should be better for battery efficiency + we've got a 2390 mAh in it so, as long as it's ramping down to the 200 MHz "bottom" that it actually should be hitting then I, for all intents and purposes, should be able to expect or even exceed that 8+ hours of SOT without issues. The Tribute has an 800x480 panel in it, the E has the 960x540 so in the long run that increase in pixels should be covered by the increase in battery amperage (290 mAh more).
This Moto E 2nd gen model should be able to do 7 hours of SOT without breaking a sweat, even with cellular/Wi-Fi/Bluetooth/location services on and functional.
At least that's my goal with it... I'm on my first full charge since I bought it earlier today and currently at 58% with 3.5 hours of SOT and that's using Wi-Fi a lot with video playback as well. I've been keeping on top of the Baltimore riots that are happening presently and monitoring things using Scanner Radio Pro as well as a lot of surfing for info and news too. So far so good on the battery life, but obviously it can be much better as long as that CPU speed can be brought under better control.

848MHz?2.6.3x kernel?

Hi guys!For the last few days(that I have my Hero rooted that is) I'm using VillainRom 10 as my everyday ROM and have tried some others.Anyway,that's not the point!
Being one of the lucky ones whose Hero can happily overclock to 768 I came to use RaduG's extremekernel and ben39's no-bfs no-whining kernel.With the second,while configuring OverclockWidget I saw that it gives a 848MHz option with auto-detect frequencies.Is it possible?I'm not asking about stable daily use,but even for some minutes for benchmarking?Has anyone achieved it?Without making their phone catch on fire that is!
And secondly,why are we all using linux 2.6.29(for total newbies I mean the kernel) while there is 2.6.32-33-34?Can't a newer kernel be compiled for use with the Hero?Newer kernels would provide native ext4 support and would probably prove to be better overall.
Oh,forgot one more!I am currently running on minimum 176MHz-maximum 749MHz(after I got a couple reboots with 768 I abandoned 19MHz for stability) with screen on and minimum 123MHz-maximum 384MHz with screen off.Should I give it a higher minimum frequency?Sometimes it lags when waking up,the screen turns on but shows nothing but black and turns off again or it turns on and everything is distorted,colors are completely distorted,background is upside down and some other unnormal things,but everything is alright when turning the screen off and back on again.Does it have to do anything with the frequencies I am using?I am running on VillainRom 10.3.
Now I have set the minimums to 160 and 190 MHz to see what happens!
Thanks in advance!
About the high MHz... I have done it with over 800 but don't max it out at 848 or your phone will freeze but anything below works And that screen **** I've also had and it has something to do with the high MHz (don't know why) but it helped me to set the MHz lower when the phone sleeps in SetCPU And at last about the kernel... It runs on the old one on Android 2.1 but in 2.2 it will be upgraded to ....33 or ....32 don't remember which...

Thanks for your reply C0mpu13rFr34k!
I know Eclair is running on the old kernel.I just would like to know if it is possible to compile a newer kernel for it.
As for the frequencies...Are my settings alright?Some too high or too low?The way I see it there is a big gap between maximum and minimum frequencies when screen on which results on the CPU working at low frequencies most of the time,thus sacrificing performance.But it helps with battery life and presumably this and the screen-off underclocking reduce the overall damage caused to the CPU by the overclocking,which is said to reduce the CPU's total lifetime by 50% or more,depending on how much you overclock it.Working at 749 I sometimes get a nice 43 degrees Celsius while charging,but that's only when charging.Average temperatures are 30 for standby and 37 with screen on(average,can be lower or higher).
And one more question.At 800+ how hot does it get?Will it be stable for some minutes to do some basic benchmarking or nah..?
Thanks!

If your phone is stable your settings are just fine even though your phone might have problems waking up if the low freq is under 246MHz (something like that) Also if you want better performance you might want to test some other freqs and then benchmark... Sometimes it makes a BIG difference if your phone is running at 691MHz or 710MHz For me my phone works like **** if it runs at 749MHz but it works like a dream at 729MHz (I think the difference was 0.5-0.8MFLOPS) Im also pretty sure your temp is fine (OC shouldn't make your phone that much hotter since the voltages in all ROMs are adjustet). If you should compile a newer kernel you would first of all need a .32 (.33?) from HTC because of hardware capabilities and im sure there's is A LOT more things devs need to compile such a kernel but i don't know to much about kernels I don't really know that much about 800+ because I only did it once and benchmarked it (MFLOPS was **** and i couldn't get them high at all) actually it slowed down my phone but you should test it. Maybe your very lucky and your phone can take it
Well,I have set it to 653min-749max with screen on and 160min-352max with screen off.Testing only!But it runs like a dream if we don't take into account a small lagging when I turn the screen on and it has to change frequencies!But it's great so far.Will see how battery life goes!By the way,tried 800,806 and 848MHz,but none worked.It didn't crash or something,it just wouldn't change to it and stayed at lower frequencies(low as 246).
Thanks for your time anyway!
And a small question...How bad does overclocking affect the CPU's life?I asked around and was told that the maximum overclock for desktop PCs is 20-25%,depending on the CPU,while needing special cooling systems,and that it can reduce the CPU's life up to 50%.Given that we overclock over 40%,how bad do we damage our CPUs?

I haven't heard to much about that actually but from what I've heard it shouldn't damage the CPU at all because of the voltage adjustments but i find that very hard to believe... Talking from personal experience my phone runs as smooth now as it did when i bought it so my CPU has probably taken minamal- or no damage at all and I got it when it had just come out here in Denmark (Europe) which is about 8+ months i think? So I wouldn't care to much about the lifetime since It's probably like 1-2 years and by that time I don't think people are using the Hero anymore Keep up the good work with optimizing and your welcome

Phone really heats up when I play MC3/GTA III for around 10-15 minutes

Hey all,
I've been noticing over the past few times I've been playing GTAIII and MC3 that the internal temp of my phone rises drastically, to a point where I can barely hold one side of my phone without having to let go every few seconds because it is so hot. From where the battery is positioned, I assumed it might be the GPU heating up, but other att gsII users said their batteries were heating up.
So,
1) Is anyone else experiencing these problems
2) If you are, has anything happened to your phone
I'm debating whether to trade it in for a new one, because I'm still under warranty.
Welcome to high performance electronics. If you push the CPU/GPU hard it's gonna heat up. It's like a desktop, if you do something CPU/GPU intensive it'll heat up. It's a simple byproduct of inefficiency.
As to batteries heating up, that could just be because they're close to the CPU/GPU. Batteries will warm up under high current draw as well.
Do you have a case on your phone? Those tend to trap heat in as well.

If your phone is overclocked, the processor will be running at the max clock you have set while playing the game, which is higher than what it's supposed to be running at, i.e., the stock clock. Prolonged usage at this higher-than-normal clock will generate excessive heat.

Yeah I don't play GTA3 anymore because of this kind of stuff. It doesn't get to the point where I have to literally move my hands because of the heat though. I simply don't like my phone getting even remotely warm. I'm just really anal about stuff like that. I fear that doing it will shorten the life of the device and I love this phone way too much to let that happen.
I'm sure it's designed to run at these higher temps since mine is completely stock with regards to cpu speed and voltage. If I can't play a game due to this, then I simply pass on the game. Same with my computer but I digress...
Download an app to check the temperature. Yes, ideally cooler the better, but the phone is designed to handle a certain amount of heat.
From what the op is describing, that is definitely too hot. Over time the components life can be shortened. But what you'll see first is your battery life going down, even quit working all together.
Underclock the processor. That can help keep the heat down. Even as low as 500mhz can pay many games. 800mhz should be plenty for most high end games.

I'm not overclocked, but yeah, same thing happens with me when I play MC3. I got scaredish since it got a bit too hot, seemed more hot than it was supposed to be.
download the diagnosis app and set it to check your batt temperature, if that gets above 45c I would be worried and think about underclocking/undervolting.
As long as your phone is cool enough to handle, don't worry. There's a lot more to it, but the electronics can take a lot more than most people credit them for. The battery is the most sensitive to temp, but so long as it's not for terribly long periods of time, you shouldn't even notice any additional degradation over the long run.

I have the Otterbox, which is probably the absolute worst case for heat efficiency

I agree! I baby this phone to every extent and I hate that feeling I get when it gets warm because I just assume the worst. I keep thinking the gpu is going to blow up or some extreme thing like that

Average day to day operating temps are between 30° and 40° celsius.

If anyone's interested, I have pretty much eradicated the heat problem while also boosting battery life and conserving performance. This was done through setCpu: http://forum.xda-developers.com/showthread.php?t=505419
The problem was that apps were just running the processor like crazy on the 1.2 GHz speed setting, and it used a considerable amount of juice that was unnecessary, heating up the battery to a ridiculous amount.
But anyway, here's the profiles/voltage settings I use:
Main Governor: 200 MHz - 1200 MHz on demand
Profiles:
- Charging, 800 max, 200 min, ondemand, priority = 100
- Temp > 44.1 Celsius, 500 max, 200 min, conservative, priority = 100
(this is a conservative temperature, but most place the *dangerous* amount of heat at 50 degrees before battery life starts decreasing, the CPU/GPU components have solder that melts at 70 degrees)
-Screen Off, 500 max, 200 min, conservative, priority = 75
-Battery <25%, 800 max, 200 min, powersave, priority = 75
-In Call, 800 max, 200 min, conservative, priority = 50
Voltages:
(I was able to undervolt by 50-75 mV for each and still remain stable, these are tested btw)
1600 MHz - 1400 mV
1400 MHz - 1225 mV
1200 MHz - 1200 mV
1000 MHz - 1100 mV
800 MHz - 1025 mV
500 MHz - 950 mV
200 MHz - 875 mV
and that's it! It's working great, I don't have the heat issues I used to, now I can play graphically demanding games and the temp doesn't rise past ~42 degrees, pretty solid improvement. I also get 24-28 hours of battery life with 2-2.5 hours of screen on time per day.
No need to worry about this. That's nowaday phones designed to be. Just normal heat.

I agree that's how they're 'supposed' to be. But things mess up. AMD processors are designed to handle heat, but they are still known for getting too hot and damaging the graphics chip. Better safe than sorry.

[Q] Huawei u8160 Battery Temperatures.

I'm running subpsyke's CM7 port on my u8160, and have overclocked the CPU to 691mhz using the the smartass governor. The processor runs at 600 by default. Any higher than 691 and it immediately locks and restarts. At this speed it doesn't reset any more often than at default, something this phone did every couple of days even before I flashed the ROM, and it never locks up.
So my question is: at what battery temperature should I start getting worried? During browsing it gets up to around 25 to 28C, but when plugged in and being used I've seen it at 36C occasionally. I have a feeling that's pretty high.
Watchtower isn't showing me any processes eating up runtime erroneously either.
I'd really like to keep the higher speed, it's just enough to view higher quality video on this toy.
EDIT: The battery temp sensor is the only thermometer on board, I think. AndroSensor picks up another one but its forever 'waiting for event' so I don't think it's really there.

Lumia 710 battery drain issue - i have an idea

Probably all thought about battery drain issue. I have an idea how to fix it. In Lumia 610 processor is weak (800 MHz). So, I had the idea that if a processor driver from the 610 put in 710? The processor will not work quite the power and flow rate will be lower. What do you think about this?
All ideas are welcome!

It's a good thought but I am not sure that it can be done just by swapping out the drivers. The processor has to be underclocked for it to go down to 800mhz, and as MS has locked down the OS hard, we don't have access to the kernel for underclocking.
Skepticism aside , if this happens it will be a huge breakthrough. Totally excited for this and will follow the development.
The CPU won't be the main battery drain or even close, the Screen and the Wifi are the biggest drains
I have my tablet overclocked from 1GHz to 1.4GHz and battery drain is no higher than it is at 1GHz, the 710 CPU won't be running at 1.4GHz constantly anyway, it will clock down as often as it can
Screen by far is the biggest battery offender. Then, I'd say GPS, WiFi, Bluetooth, in that order, especially when any of these is in use. A CPU shouldn't only be underclocked, but also undervolted in order to get the most "gains", gains being a relative term here, cause you lose in performance.

Is my Z5c throttling?

Hello guys,
I bought this phone about two days after release and was pretty happy with it. It felt like the Snapdragon 810 didn't overheat at all and the performance was far better than on my "old" Z3.
Reason enough for me to try PPSSPP and emulate some good old games. For example MHP3rd ran at 100% speed in every area in-game with no frameskip activated.
But after some time (I'd say 20-30 mins) the cpu throttled a lot. The game speed was only at 50% even though the device didn't feel THAT hot (I've seen/felt hotter ones).
I tried the same thing again with the app "CPU Temp", and it seems like the CPU temperature never exceeded about 58°C. I'm not sure about smartphone CPUs but as far as I know, most chips can take up to 80-90°C until they start throttling. My Z5c runs at 52-58°C perfectly fine, but suddenly starts throttling for some reason.
Is it the CPU governor that tries to save battery life? I'd probably need to root the phone to "fix" this, but there are no roots available yet.
Or is it something else? Is the max. cpu temperature set too low? Could it be the S810 has no real temperature sensor and CPU Temp shows me something completely different?
Thanks in advance!
Greets,
Uftherr
I think that Sony it's throttling the CPU more to be below 58°C than to save battery life.
Try with the latest firmware (released today at PC Companion) it seems to be a little more snappier (maybe its a placebo).
I don't know why because the kernel is from the same date.
I consider that they should let the phone gain 65°C to increase the performance (at heat cost).
