Is my Nexus 5 a defect? Slow CPU performance. - Nexus 5 Q&A, Help & Troubleshooting

Hello everyone,
I have taken many benchmark tests and all of them fell short of a Galaxy S4 and even some other Nexus 5s. Here are screenies:

The first Nexus 5 I had I noticed this! Antutu would show it on comparable performance with the HTC One X! I swapped phones unfortunatly but I have another Nexus now. Haven't run any benchmarks but Minion Run runs like crap

Benchmark apps run horribly on this phone. It throttles way too soon. That said, benchmark apps are useless. Nearly all major brands are known to "cheat" on them by temporarily boosting performance above what you would normally get during use. Especially Samsung.

like what was said above, dont trust benchmarking apps. They are pointless. Download cpu spy and better battery stats and see what running when at what cpu speed. as long as your hitting top cpu clock at some point (like when playing a game), the hardware is more then likely fine and probably just needs some kernel tuning to get it to your liking

That said, there are people who get amazing results... One last thing to note, Franco kernel hates my phone. I get random reboots at normal clock speed 2.3ghz. Or is it my phone...?

It depends how many apps are in teh back ground, the phones temp, and all kinds of stuff. I have gotten as low as 17k and as high as 29k.
Also - I don't think the majority of benchmark apps have been optimized for 4.4 yet.

Damn this thing gets hot!

Playing games is usually the culprit, but my nexus sometimes gets hot even after web browsing... How hot does your Nexus 5 get??
I can't say mine gets hot... I use Faux Kernel with the recommended settings and also undervolt my phone. You can also fiddle (lower) with the max frequencies for the CPU and GPU to your liking. You'll often find that you have more than enough power to handle games and can reduce the frequencies quite a bit.

I dont want to mess around with Kernels and Root just yet.. Once the big ROM's start to pick up speed and become stable thats an option... Hoping Google brings out a software update to reduce the heat, and do something about the Camera, I honestly think if this had a Camera app which was optimised for the Camera it would be better than the S4 and the likes, when you put the S4 on a fully stock rom, the pictures are horrible, on the Nexus 5 they're just average... If it had the S4 Camera App who knows what it would be like!

Have some faith in the Devs. There are a couple of ROMs and Kernels that are perfectly stable. Thanks to the Faux kernel I have seen a ton of improvements over stock when it comes to performance and battery life.
I came from the HTC One and my nexus hasn't gotten near as hot as that would get.

N4 vs N5 speed

Anyone else feel their N4 was faster?!
My N5 feels same speed as N4 but bench mark shoes my N4 was faster..
Speed test internet in N4 was faster as well!
Why? Because in still on stock rom with N5?
Sent from my Nexus 5 using xda app-developers app
Maybe cause you was on a cooked ROM on your N4... Same di for me, not really slower but something like "hesitating"..
Sent from my Nexus 5 using XDA Premium 4 mobile app
I don't know what benchmarks you were using but my numbers show it beating out just about everything on the market, except for devices that were cheating their scores.
I had an N4 stock and the N5 stock is way snappier/faster than the N4 to me

My Nexus 5 is noticeably faster on both benchmarks and to the human-eye. I'm completely stock also.

I used antutu on N4 with PA and got around 26,xxx. N5 with stock I get 22,xxx..
Internet speeds via speedtest.net app
N4 H+ 20-24mbps
N4 LTE 24-30mbps
N5 H+ 15-18mbps
N5 LTE 18-22mbps
To the eye, moving around menus the N5 seems same speed.. although it does boot faster.
I also get more bars on the N5 on H+ and LTE! So I would think it would get better speeds.
Sent from my Nexus 5 using xda app-developers app
The Nexus 5 is much, much faster than the Nexus 4. PA ROM is probably causing some dirty results in the benchmark, because it most certainly isn't the correct result. Hell, I just ran the benchmark on my N5 and got nearly 24,000 with other apps running. There shouldn't be such a dramatic range in numbers. It might also be Antutu, which is probably why no tech reviews use it.
Also, at least for LTE speed, I've seen over 45mbit/s download on my N5 already. It's capable of doing just great on LTE. Keep in mind that these speeds can vary DRAMATICALLY from one moment to the next.

Fps drop games after few seconds

I have noticed (since today this is happening to my device) when i start up a game, it runs very smooth. But after a while it begins to stutter and it is just not playable anymore.
I play real racing 3, i have seen videos on youtube where they are playing this game on ultra high quality and it runs smooth, but on my nexus 5 it is laggy and not fun to play.
What can cause this problem? This never happened before till today.

It might just be thermal throttling. Let the phone cool down a bit and try again later.
Thank you for your reply, i will try again tomorrow then. But i hace a feeling thay it will comeback because my nexus gets a little hot while playing heavy games

I Have tried it now, still having the fps lag.

Wrap it in a shirt, throw it in the freezer. Try to get it to like 20 degrees Celsius (use CPU z app to check temp) then play the game. If it still lags, then you can confirm its not thermal throttling.

Sorry i am not planning to root my phone, it gets hot when gaming and then the fps drops, am i the only one having this issue? I hope for not

Hi,
You have a quadcore phone running at 2,26 Ghz (ok, not all the time but...), enclosed and without a cooling system, so when you play an heavy game "for a while" expect some heat then thermal throttling... (the CPU freq decreases according to the CPU/battery temp, maybe the GPU freq too but I'm not sure about that) so you can have at a certain point some FPS drops... Nothing more. And in a game it's not only the GPU that plays its role but also the CPU.
If you don't want to root (at least unlocked) there is nothing to do (like decrease the max CPU freq to limit the thermal throttling, undervolt, or tweak the thermal management), maybe trying to play less longer? Have you some "huge" apps running in background? You don't play while charging your phone?
Thank you for your reply! Before all this i could play deadzone 'shadowgun' for like 1hr without any problems.
Now i cant play any high quality games for 5 minutes because after the 5 min it starts running laggy. That is what i found strange
Its very sad because i see videos on youtube where they play on hughest graphics with real racing 3 and other high end games. And mine cant even run smooth for 5 mins.
All other things besides the gaming runs smooth

Hum...What have you done between "before" and "now"?
Maybe a weird question but maybe there is something...
What is your room temperature?

I havent done anything between then and now (maybe installing some apps but thats it) my room temperature is normal. 21C - 18C i live in a cold country haha.
Sorry i forgot that question with apps in the backround.
I never have any apps running in the backround, i always use task manager and i always close the recent apps.

Maybe some useful info: I have ran a antutu test and my score was 21k.

Ok...
How did you measure the FPS drop? Does your game have really some lags?
In any case I don't know a single game with a solid and constant FPS..., for me nothing wrong with your phone, try a factory reset to see...

Nope, or at least it could confirm thermal throttling that's all, full stock you should score about 28 000-30 000...
Thank you for your reply, realy appreciate it! i will backup my apps and try a factory reset.

Fac. Reset worked i guess!? Still a little laggy but it is less noticable for sure! I am downlaoding real racing 3 now, hope it will run smooth

Also you should be mindful of the heat coming from your phone. You say you can play games for hours in the past. I know after 1 level of dead trigger can have my phone @ 105 degrees easy. I can't imagine playing for a hour straight with ultra settings. Heat is the biggest enemy to your CPU and Battery.

[Q] Safe to overclock?

Would it be safe to overclock to 2.8GHz with the CPU Governor as "intelliactive" and leave it there for normal use?
ROM: HD Revolution 5.5
Kernel: Faux
Probably.

With some tweaking it should be stable. My one question though... Why? Who needs that much power lol

The real question is why not? LOL. Honestly though I just like finding new things to do with my phone and coming from a locked Galaxy S4 I have to say I'm enjoying the amount of things I can do with this device that I couldn't on the S4. The extra 600MHz was because I was hoping it would drop any chances of lag with my favorite apps & Xposed which always seems to cause a delay or two for me. On the other hand I like squeezing what I can out of it. Same with my Desktop too, get maximum stable over clock and stick with it. ;D. If there's some downsides such as life shortage feel free to mention it though because I'd rather know early on than when it's too late. Sorta the point of this thread

I've got my i5 2500k overclocked to 4.3 GHz now stock voltage . As for life shortage its hard to say. I would monitor temps on stock vs over clocked and compare. As long as it doesn't get considerably warmer which for mobile would be 10° more or less you should be fine

Well with normal use it gets like 40-55 C (CPU) and during an Antutu benchmark just at the beginning it hit 75C sooo not very happy with that.... especially considering that's in the highs for a lot of desktop processors, can't even imagine how bad that must be for a phone processor LOL. It was @2.803 MHz with voltage of "1130" & ondemand governor. Not so sure as to what "1130" is based on though as I'm new to mobile over clocking, guess I'll figure it out tomorrow!
Edit: Forgot to include that just a few minutes ago I flashed a new kernel due to some random lag, old one never hit above 50 even on tests (with intelliactive). Also using ondemand/interactive now. Gonna re check the differences on those two governors tomorrow and decide which one I wanna go with! : D

[Q] [RECOVERY] Is there a recovery like this for the N5?

http://forum.xda-developers.com/showthread.php?t=2898705
I'm curious if there is a custom version of TWRP for the Nexus 5. I think I've seen screenshots that have temp of the CPU on the N5, but I haven't been able to find a custom version. If there is, could someone link me to it please? Thanks in advance!

Specifically something that doesn't run all CPU cores at max speed. If in recovery too long, that could lead to hardware damage.
Sent from my Nexus 5 using XDA Premium 4 mobile app
I've never heard if any troubles with phones using full speed during recovery. In that case you shouldn't play heavy games (or even simple games), watch movies, stream video and so on. Don't worry about this, the weak parts of a phone are battery, screen, buttons, orts, not the use of a recovery. This is cosmetic without any proven effect, like UV for preserving battery and so on. Even using it ten minutes every day won't cause any damage.

Not really. CPUs are built to be able to withstand this. Damage comes from excess heat and higher clock. I.e over volt.
Alright, thanks everyone.

Just in case anyone doesn't know this, CPU load / utilisation and CPU clock speed are not synonymous. A CPU can be clocking at 2 GHz or whatever but only be under 5% load. Sure, governors will usually ramp the CPU clock up under high loads. But if you think about the performance governor in Android for example, it sets the CPU at max frequency all the time, but the load will not always be 100% in fact it will hardly ever be 100%
Also if you look at a laptop, it will be clocking high, most of the time maybe not always max, but often not far off
Most android governors will get you to max clock long before 100% some even at 50%
