I've heard that having your screen off setting to 128mhz that it drains more battery than 284mhz and does not let the evo perform correctly. Is this true?
I have mine to 128mhz atm and dont seem to notice qany diffrence in battery loss to when it was at 284. I have only had it this way about 24 hours but so far not a big diffrence one way or the other
Haven't noticed any extra power drawn, only thing I noticed and hate is that when you wake up it can lag bad, until the profile changes to a higher clock

Im interested in this also. I saw some people say 128 drains more battery but nothing to actually show it. I am running some tests of my own currently. Im sure it will be hard to see a difference unless there is something crazy going on.
It must have been me who posted about the 128Mhz bug first.
I'm running latest ota stock rooted, latest ota radio/wimax with Netarchy's 3.0 or 3.7.3c kernel.
I noticed that when I had 128-998 set on boot, the phone wouldn't sleep properly, and the battery drain in standby mode was ~3x what it normally was.
The normal battery drain for my configuration is about 1% an hour in standby.
If you are running a different rom/kernel, I suppose, it's entirely possible not to see this problem. Test it yourself and find out.
I have had my Evo clocked at 128 for Min and Max for about a day. I initially thought the reports of uneven performance were wrong, but a few runs of Pandora during "Screen Off" did cause some long pauses and some FCs on a couple of occasions. I suspect this is why many recommend increasing the clock to 245, especially when you have process heavy apps running.
I personally don't think the difference in such low clocks will have a significant impact on battery life, but for those of you who get the warm and fuzzies from the absolute lowest setting, I have been playing with my Min @ 128 and Max increased to 245 for a couple of hours. It's jumping out of the low clock much smoother (I can immediately drag the lock bar down) and I haven't gotten any FCs while using Pandora with the screen off. I have ran Pandora with the Screen Off and the "adb shell powertop -d" from my terminal. It is reporting that my Evo is staying in the 128 clock, but, like I said, it's transitioning to higher clocks without a hitch when I turn it on.
Hope that helps.
I've also found that 128 is just too low for things to work properly. It stutters a lot when the screen comes on and things like music also stutter.
Having tested this for a little over 24 hours in response to the increased battery drain, I could not tell any additional battery drain still after 24 hours. On the flip side i could not tell of any additional battery saving either. At the end of the day i was in my normal range.
I do not use the Stock rom but do use Netarchy's latest kernel. So ti may just be a stock rom thing. I will agree that the screen comes on sluggishly and music will skip if you have it playing with the screen off. Since i was unable to tell any significant benefit from lowering it i will be stick to 284.
I prefer screen off profile to scale down to 285mhz as opposed to 128mhz. I know the clock differences are minute, but the phone feels more responsive and ready for action when woken up at 285mhz. You can feel the 128mhz drag.
Due to some of the instability I've gotten, I've decided to bump up the Min to 245. It runs much smoother and I cannot see a difference in battery life. I think the occasional lag and FCs that 128 might cause will hurt your battery life before the increase in clock will. I'm now with the "128 is not an option" camp.

What is your screen off profile, min/max? Obviously 285 is min, but what is your max? What about when the screen is on?
I have my screen off setting for 245 min & max. I get no stuttering pandora and it doesn't **** itself when I turn the screen on. The transition to normal is smooth.
I am getting over 40 hours on battery....
with the set-up in my signature below.......
I have Set CPU set to 245/128 with screen off. I get almost no drain with phone resting. Went to be last night and when I picked up my phone this AM, it was still on the same %. This has been consistent for the last 3 nights.
If you go to the baked snack rom thread, towards the last two pages as of today....I discuss my set up. Others are experiencing the same kind of battery results.
I get no hiccups from resting to on. Pandora plays fine. If it needs the 245 for Pandora or such, it's there. If not, it goes down to 125 and uses almost no battery over an extended period of time.
I just tried setting 128 as min and 245 as max for screen off and my phone got stuck in a boot loop. After sitting idle for a few minutes it started rebooting on its own.
I had to remove the battery and was then able to get into the OS. I have since set my phone back to 245 . I will update if I find out this was happening for another reason or if I try 120 again.
I had noticed some slow performance from my Galaxy Nexus recently, (while playing games) and decided to do a little investigation of my own. I realized that my device was spending almost all of it's time at the idle 350 MHz.(using CPU Spy) Even though the games were lagging, the device was never clocking up, an always staying at 350 MHz. After a 5 minute text run, the device spent 3 minutes 26 seconds at 350 MHz, 1 minute, 13 seconds at 700 MHz, 4 seconds at 920 MHz, and measly 15 seconds at 1.2 GHz.
You can see the change in gameplay too. The test run was Super Mario 64 on N64oid, and the game was somewhat laggy, with occasional ten second or so bursts of smooth gameplay.
I've seen this game played on a Galaxy S played perfectly smoothly, and although the resolution is increased, the bumped up RAM, CPU, and GPU speeds should be able to accommodate that. As a note, even when played without stretch, and with the menu brought down, (which results in the smallest possible screen) the device still lags similarly to full screen mode; leading me to believe this to be CPU rather than GPU limited.
One last thing to add here is that during a 5 minute idle control test, (sitting on home screen, screen set to 10 minutes till auto off) the device performed as you would expect, with all but about 3% of the time at 350 MHz.
Not sure why you are seeing this, I have no problems playing n64oid. I noticed a stuttering effect like you described when running the first overclock/uv boot.img when it was posted, but I have since not had any problems.. perhaps a new boot.img is in order?
I'm running completely stock, have there been any known issues with N64oid on stock?
Hi Everyone,
Just wondering how your Nexus 7 runs under the new OS? I notice my device getting higher temperature than before, especially when playing some games. For example, with CPUTEMP and Smash Hit, CPU's temp was around 50-55C on Kitkat but now it is 65-75 on Lollipop.
Would be great if someone can run the same test and see if you get high temperature on this game.
Thanks
I can attest to this myself. I use the same app (on a N5 and N7) and I've noticed that the feel in the hand, while doing normal stuff with the same usage pattern, seemed hotter than normal. So I launch the CPUTEMP app and run the overlay, put the N7 to sleep for 15 minutes to idle. Temp starts around 36 C when first turning on the screen, then it ramps up to 44 - 50. Then while actually using the device, (e.g. surfing the web, email, basic stuff) the temps will go up to the 50s and 60s easily. If I leave it at rest on the homescreen after using the tablet, it idles around the low to mid 40s. While video chatting online with someone (hangouts / skype / etc) it will ramp up to 70s, then 80s, and finally cap out at 95 C. (5 degrees before S4Pro SoC maximum?) A video chat will last 2 - 2.5 hours on a fully charged battery, and the heavy SoC throttling affects the frame rate / responsiveness of both my front / back camera preview during vid chat and the entire OS. Downloading an app or two brings the temp 55 - 61, and then installing them (due to AoT compile) from 61 to 72.
The same goes for my N5 also on Lollipop, to a lesser degree, but nonetheless, it runs higher average temps than I noticed while running KitKat. Both devices appear to drain battery quicker on Lollipop, especially during use. That's not even considering LTE / mobile data use, since these days I'm here at home using WiFi all the time.

Yes. You are correct. Even i face the same issue. The device gets heated even on playing candy crush / angry birds which was not the case with kitkat 4.4.4.
Hello. I have noticed that my mi5s has some lag while playing asphalt 8 even at medium settings. After doing some benchmarks with 3DMark I realized that there is a drop in performance at relatively low temperature.
At "Ice storm unlimited" I have a score around 30,000 when the cpu is cool. However when I hit a 36 degrees of Celsius I am around 27,400. Furthermore, if the temperature increase at 39 Celsius , the performance drops even more and 23,500. This gets even worse when I hit 40+ Celsius where the score drops under 20,000 and if I semi-covered it with a cloth to reach higher temp it gets around 16,600 at 45 degrees of Celsius. After that it need to cool down to 33 degrees of Celcius to restore its performance
Needless to say that these temperatures are very easy to reach when you are playing a game. Has anyone noticed something similar? Any suggestions?
I have the 3/64 version with the 7.7.20 developers. Same issues were faced with the 7.7.6. . I have not tested in depth with the global rom but I think I had similar issues (it was only for a day). The room temperature is around 30 degrees of Celsius.

If you're okay with the high temperatures then you could disable all the CPU thermal throttles from any kernel manager app, though you need to be rooted.

I was thinking something similar but I do not want to disable it fully but just increasing the threshold by 2 or 3 degrees of Celcius. I am rooted but I am not sure how I can do the modification. From some quick search that I have done there should be a file named thermal-mplampla.conf (I do not remember the exact name) where you can modify it but I am not sure by how much should I change the respective lines for just a 2 or 3 degrees increase.
Anyone that have been playing around with thresholds and have any tips or guide before messing around?

First of all, that isn't the CPU temperature but the battery temperature. This phone actually has fantastic thermals due to its aluminum back and well placed SOC. No wonder you're getting throttling, you live in 30°C and you're playing games, what do you expect? Every phone on the face of the earth will throttle to that level. Just saying, your CPU is running probably around 70-80°C while playing intense games. So if you continue to play, it will eventually heat up the rest of the phone.
40°C destroys a batteries lifetime and 45°C everyday will reduce your battery within half a year which is why they throttle phones. Hell my One plus 3 in 30°C weather will throttle like crazy and that's the best phone in terms of throttling. Its normal. Stop playing crappy games like Asphalt 8 in 30°C and go enjoy the sunny weather instead.

Actually the truth is somewhere in the middle. I have used an app called "cpu temperature" but if I check the battery temperature it shows exactly the same degrees. So I guess it mistakenly shows the temperature of the battery. Do you have a more reliable app to check cpu temp?
On the other hand, 30 degrees of Celcius is not that high. In the winter usually we do not let the room temperature drop under 20 degrees since we use heating. Nevertheless, I will let it as it is for now and check again after 5 or 6 weeks where the temperature should be cooler.

You need a rooted phone to see actual CPU temperature. The best way to do this is get an app called simple system monitor (blue app icon) and go in temperature zones and you'll find a bunch of sensors there. There's a bunch of them that are for the CPU and you kinda have to figure it out yourself (I don't know exactly which one it is, one of the tz_sensor ones) by running a CPU benchmark and finding the ones that show the highest temperature. If you were to remove thermal throttling, and maxed out the CPU and GPU, you will see your CPU hit around 100-110°C and your phones gonna shut down for protection. And I'm in Canada so 30°C is extremely high haha.
Hello, I have the S9 for almost a week now and i think its getting hot sometimes with just a normal use (facebook, internet etc. not gaming). Whats the ideal temperature is should have. i think its getting warm on the upper screen and a little on back at camera place. While charging is a little bit warm but i think its normal. Should i send it for a test or getting a bit warm is normal?

Have you looked at the battery or CPU temperature for your phone? I'm wondering this too about my own. I sit at around 85 F (29.4 C) while it is in my pocket. It gets down to 72 F (22.2 C) while on the table. That's about the room's temperature.
Definitely getting warmer during certain use than my S8+ ever did (I remember noticing that it pretty much never got hot) or even my Note 8.
I have an Exynos version though so probably has something to do with how inefficient it is when the cpu ramps up.
Haven't noticed any warming on normal use. When gaming, yes specially pubg. Not too much coc.
SD variant.
Is it about 22,5C CPU temperature when not used, its the same with rooms temperature. after 15 mins of use for example scrolling on FB it reaches 35C both battery and CPU (from AIDA64). Battery also drains fast. Last night 30 mins of scrolling on FB lost 10. Screen brightness is always less than half. and only WiFi and sync are enabled. AOD disabled. Bixby button and bixby home page disabled. While sleeping also battery loses about 8-10%. Yesterday with 15 mins driving with google maps the screen was burning.

Hello brother, I was gonna buy s9. How's the gaming performance specially pubg? What max settings can it run? Thanks.
Anyone knows where can I locate cpu temperature file of s9?

Honestly, i would recommend it. Even the plus. For me tho carrying more than one phone for work and stuff it got old having the s8+. But for the s9, man the stereo speakers sound great. Much better than last yr but of course they werent stereo so diff is noticeable. As for pubg, i really have messed with resolution and looks great i think im on fhd. While playing tho the s9 does warm up, havent checked exact temp but its noticeable. Cant say if it does the same on the s9+. Hope someone can confirm.
I look at it this way, like having a macbook air for gaming vs a macbook pro, the air will make more noise and warm up vs the pro.
