Hello,
I've updated my Nexus 7 first-gen recently to Android 5.0 and since than have spent a good amount of time using it. I use the tablet for work and fun through out my whole day, so snappiness is a big factor for me. With the 4.4 update, the tablet just got a lot slower, sometimes I needed to wait for a few seconds before I am able to kill a task. Clearing cache didn't fix the issue.
Made me think about that 5.0 update a lot. (Note that I actively started using the tablet only a few months ago. I had it for 2 years but broke the screen 3 weeks after buying it and only now I decided to repair it.)
The 5.0 update it self took a good 45 minutes. When I loaded it up for the first time, man it was buggy, I couldn't complete a single task without it bugging out. All of the Apps and settings were there untouched. The first thing I did, was go into recovery mode and cleared the cache. Then I cleared the cache for every individual app. And that boosted the performance by 100%. Next, the animations, I cut them down to 0.5x and turned on GPU rendering (just for testing) turns out that helped out a lot. I didn't notice a difference in load times, like some articles suggested.
However there are a few quirks, the sound lags behind the slider, so if I crank up the volume to MAX it will take a moment to do so. I often found my self having to tap the apps drawer button more than once to open it. And the killing of tasks is not as easy as before, now you have to slide from one side to the other in order to kill a task you can't just kick it to the side. Also, the auto-brightness is really aggressive so I disabled that. The WiFi status, when you click on a WiFi connection seems to be broken since in portrait mode all the letters are separated, and at first I couldn't make out any of it. And the biggest downer for me is the keyboard, I think they didn't do any favors with it. I have larger thumbs and it will take some time getting used to the keyboard. These are all small things, but they affect my experience.
Now the good stuff, where do I begin? The interface, it's great I like the design and the contrasts. Performance, I guess that's the biggest question since this is not exactly cutting edge hardware. To summarize it, it's good. I haven't had any issues since I cleared the cache, apps are running as they should, games as well, multitasking is as expected, fluid. Later on I switched the animations to 1.5x and 2.5x. no issues there. Boot up times, something completely irrelevant to me, but since there are people that would like to know, it takes around 30-40 seconds to boot up. However, Chrome is still the biggest enemy. If you want something to make your tablet miserable and make you wait and get frustrated because of it's unresponsiveness, you won't need to search far, just get Chrome.
All in all, the update was a step up, and an improvement.
These were my 2 cents on the subject. Hope it was of use to someone.
thanks for the review. I also updated a few days ago when the ota came through. So far, I'm experiencing terrible lag. I don't have anything stored on the N7 and don't have many apps. There is a ton of available storage on my 32gb. I did a factory rest about 3 months ago, as I like to every now and then to give the N7 a fresh start. I think I may have to yet again and keep my fingers crossed. Unfortunately, it's unusable at this point.
My experience has been variable, but not unexpected. In the past I have had issues with installing OTAs resulting in poor performance -- sluggish response to touch, certain apps immediately displayed odd lag, etc. Going from 4.4.4 to 5.0 was no different. So, I performed a factory reset and the effects were stark. The performance is exactly where you would expect it to be for Lollipop i.e. it is smooth.
HOWEVER, all is not well. There seems to be a set of problems that I suspect is related to Lollipop utilizing the ART runtime. Certain apps, even before performing a factory reset, were really really slow when running the first time. I have experienced this before: when I tried out ART when it became available on the Galaxy Nexus. Two common apps this occurs with are Facebook and Mint. Who's to blame? The app developers? Google? Don't know but hopefully these issues get resolved soon.

Ugh, that is quite an issue. Have you tried wiping the cache? You should check your usage, you might be able to find out what's hogging your system, unless it's the OS it self.

I also tried out the ART on some devices, mine were not even supported. There were a lot crashes but I also noticed some performance improvements.
Does factory reset also wipe the cache?
My Lollipop experience with my 16 GB WiFi-only Grouper isn't as good as yours. First, I thought I messed something up by rooting it with NRT, but after a manual factory image (flash-all.bat failed out of the box) without root it didn't get any better.
Most time its not as responsive as my N5, I've already had 1-2 minute hangs followed by hung apps (Google Search/GNL, system in most cases) and heavy lagging under most conditions. From time to time its getting close to 75-80% of the smoothness experienced on the N5 (which has better hardware, of course).
I have no idea what went wrong, I've already enabled 2D GPU hardware acceleration, but I'll definitely wipe the cache in recovery once more - you never know...
Thanks for the extensive review - Chrome is just a pain in the a** if you don't have at least 2 GB memory available.

I suggest wiping cache, because you get to keep your apps and settings.

One thing I forgot to mention is that after the cache wipe the tablet was fairly fast but I also went into Settings > Storage, and noticed I have a lot of app data which frankly shouldn't be that much. I then went and cleared cache manually on every app and as it turns out, I managed to scrape off another 1GB there. So, I'm not sure how that would affect the overhaul system performance but it sure helped me get the snappiness I have right now.
Looks like wiping the cache had an impact on performance. I wasn't able to play around much, but it definitely felt faster after first reboot.
Too bad I just noticed my user partion only had 6,x GB (8 GB image obviously) - there are so many ways you could f**k up an Android system - so I'll have to format user data once more, approximately the third or fourth time in the last week.
Sometimes I understand why people fancy those awful Apple devices, but let's hope the speed boost persists.
Go in and delete all the apps in system folder that can be installed from play store and are not needed. After installing the lollipop images you have 11mb in system which seems to be main cause of lag. I freed up like 160 mb and no lag or stuttering. Not sure why google kept things like dialer and other things unusable on the tablet in there.
Also get now launcher and delete launcher.
For even better performance get faux kernel (Set kernel up to his recommendations) and/or install aosp 5.0 F2FS with minimal 5.0 gapps.
Oh I do have a problem with WiFi being weaker on 5.0 though.

i am getting terrible lag too. last week i updated with the OTA file. wiping the cache improved performance but only for a short time. i guess eventually if ii want the speed back on my 2012 nexus 7 i am going to have to root and go back to jellybean

Thanks, that sped up things significantly. It's definitely a memory problem, because event on full stock setup you're getting glances of Lollipop smoothness.
But WTH is Google delivering a potentially lagging factory image? Couldn't they just resize /system by default in order to fit in all apps nicely? Well, that's Android - if it doesn't work, you have tons of options to fix it.
After my old N7 screen broke, I got a new refurbished 16GB unit for about US$100.
Had some bootloader issue earlier while trying to flash lollipop, and had to revert back to 4.2.2. Then it got all the OTA up to lollipop, and is running really well since.
Loving it now, better than most non-lollipop newer tablets around...
Lollipop is big disappointment. I hate new notification (double swipe down to access settings)
I am back on 4.4.4 Slimkat rom with Legokernel and f2fs
now is system smooth without lags
Listening to some of the advice in this thread, I rebooted into Recovery and wiped cache (I did it 3 times, because why not, right?)
In addition, I went into the developer settings and turned OFF "Force GPU".
After doing both of those, my performance seems to have greatly improved (specifically Chrome, which was borderline unusable).
For reference, I flashed the factory image from 4.4.4, and didn't get it OTA.

Not any more! I have three new iOS devices and things are far, far worse since iOS 8 dropped. Apple now holds the lag crown. At least with Android you can revert back to earlier versions that worked. With Apple all you can do is whimper at the master's feet.

UTTER nonsense. Stop it. System being full affects nothing; it's read-only.
Is there a way to disable the storage encryption that is enabled by default? Disabling this apparently had huge performance upgrade for the nexus 6

understand what you are saying but after doing so i have no lag.
Have 2 x 2012 and both were lagging. After trying other things i deleted stuff in system and both are very smooth now. Very happy with them.
Even wiped and re installed one and just deleted stuff in system, to make sure it wasn't something else or a combo of things i did prior.
So I want to start this out by saying this isnt a Note 4 vs Nexus 6 thread or a complaining thread about how the Nexus 6 sucks.
This is a thread to try and figure out the culprit of an issue I think a lot of us are having, but not all of us.
I was running Euphoria OS for a while, loved it. But there was one nagging issue, it would stutter. It was almost as if there was a delay and the device couldnt process all the frame and would drop them. It was still responsive, just not fluid at all. It wasn't on every single screen or animation, but it would appear on every unlock, opening certain programs and almost always on swiping in a sidebar menu. It is very very noticeable if you put Phase Beam or Sun Beam wallpapers on, the animation was not even remotely smooth. I tried different Kernels (I was decrypted BTW) and all of them showed the same behavior. I then set my governors to Performance to speed up the ramp up time, no change. I adjusted the DPI, no change. Nothing I could do would get rid of the janky issues.
I chalked it up to the ROM and installed the nightly CM build (1/20), the exact same issue appeared even without signing into my Google account. Just the ROM and GAPPS were flashed. Switched to another AOSP (modified) based ROM (not CM based) and the same issue happened again. It seems that only stock unmodified ROM's run smoothly on my device.
Is anyone else seeing this? Does anyone else have any thoughts as to why I am seeing this. I know I am not alone, a few people on Reddit said they saw the same thing on Euphoria (again its not the ROM's fault, its something else).

Well, I get the unlock stutter and some other subtle stutters on every non-stock kernel that I've tried. It happens consistently, then disappears completely once I flash the stock kernel. This is on 5.0.1 stock, though. I've only been on one AOSP ROM briefly and experienced the same.

you have to play with your cpu, and set it up to run how you like it. it doesnt happen on its own, you have to do it. unless you really like how the roms stock kernel runs.

Like I mentioned in the OP though, I have run all AOSP eligible Kernels on various governors and settings with no change. However, If I run any of the kernels on a stock based it runs like butter.

So if you run CM or any of the others on the default Kernel you are fine, but not on custom kernels... Interesting, I cant recall if I used the stock CM kernel or not. I know Euphoria ships with Lean so It wouldnt matter there.
edit - Dont you lose theme manager though? Or do you use the app to set the SELinux to Permissive?

No, I'm saying that I experience the same stutter you're describing (particularly unlock) on the 5.0.1 factory image using any custom kernel. It goes away once I flash back to the stock kernel.

Oh, I thought it just ran it harder. I usually run Interactive.
It sounds to me like all the different rom makers are including some common change in their kernels compared to the factory kernel. Not all that surprising, since when one person makes a change that everyone likes, everyone will do a pull and bring in ALL the changes from that kernel (including the bad ones).... and or everybody forks someone, who is probably not AOSP. CM tends to be a common place to fork or pull from.
After 8 months google finally fix the memory leak in android lollipop. Thanks :crying::crying: Am I dreaming?
Having the memory load increasing is not, in itself, a memory leak.
The Nexus 5 comes with 2 Gb of RAM, the goal is not to have memory load below 300 mb in every case (or you can buy a 512 mb-RAM smartphone)
The leak is a bug in memory management which increase memory load without any limit, thus slowing the device and crashing it. I did not experience this under 5.1 with Franco and stock kernel.
I can confirm that franco kernel does not solve the issue. For me the issue is easily reproduced by opening farm heroes saga and swiping it away, After a couple of times the system ram goes up to 1.4gig

and btw to be frank i'm not having any memory leak or any other buy on 5.1 and i feels everything even better than KK also battery life is as good as KK after 5.1 for me
and finally did you do factory reset After flashing factory image ? if not do it , it seems unnecessary to lot of ppl to F.reset after fresh install but it does solve many problem so do it if you didn't and remember it for every time you flash the rom :good:
Issue stared and '+1 confirmed'.

The same problem with franco kernel, bad luck.
To recreate the problem, simply start a game like Farm Heroes Saga, then close it by swiping away. For each time I do this the system memory increases 100mb or more until there is no more space and then cell phone stops responding. Additional I noticed than when I start Farm Heroes Saga for example the free memory on ‘Show Cache Processes’ is negative as can be seen on the print I took, and there is no free memory, this problem can be recreated even in the first minute after boot simply by starting the game.
i don t know if is due to the memory leak but after 3 days (fresh factory image flash) i m facing the annoying launcher redraw and high system memory usage:780 mb with 1,2 gb of peak

I dont want to create a seperate thread so I am asking here. Got Nexus 5 a few days ago, started reading about 5.1 update and memory leak issue. Tried to update to 5.1 but gave up(usb driver issue). Today I noticed that ram usage for apps increases and does not drop down after shutting down apps (games mainly). System ram is constantly about 300-400 but app ram got from 300 to over 600 in about 6 hours. Is this also a memory leak or maybe apps just do not completely shut down?
Memory going up does not mean there is a memory leak, it means memory no longer in use has not yet been garbage collected which is fine.
Yes, I wouldn't go purely on what the stats say in Settings > Apps > Running.
I haven't made my mind up yet - memory usage according to that screen is even higher than it was on 5.0.1 yet apps aren't killed anywhere near as often. Of course, it's early days though.
It's been said before, but sadly the new "norm" is now becoming 3GB RAM for high-end devices... and most new versions of Android are going to aimed at running best on the new handsets. I suppose that's to be expected.

Of course it is,just to force older phones users to buy new high end Android smartphones with more RAM. Now 3GB of RAM s getting standart,next year 3GB of RAM will get too little and 4GB of RAM will become a standart and so on..This is how marketing works.
My N5 (Factory Reset then Flashed Factory Image then Factory Reset) is up since 73 Hours, it uses acutally 490MB RAM for System and 898MB RAM for Apps,
in these 73 Hourse the App-Drawer was not redrawed once. I hope it will run like this for a long time.
The only thing that hasnt work, was the flashing with the Flash-All.bat.

exactly ! but ppl need to understand that what they need with phone.
i don't see any app that need more than 2GBs for ram on market plus multitasking is exceptional in N5 for me bcz i don't use tons of chatting apps who always runs and eats all resources of phone , i use heavy games and N5 still works great with highest graphics...and i bet none of Samsung or any other premium devices works with them as impressive as this 1.5yr old device still do ! so for me N5 is still more than enough
phone shouldn't be excessive better in specs than what you wants from phone. Bcz it does't make any sanse unless one have lots of money and he/she only want to waste it one way or another
I thought this was fixed at first. I picked up my phone this morning and went to check news and the whole thing was froze for like 5 seconds then starting working, but stuttering. Do I checked apps and low and behold I had about ten apps restarting, just like in the previous lollipop. Except this time I only see half my apps restarting (so far) instead of nearly all of them.

sounds like almost my case
I've read several android blogs they claim damaging, HTC, ect have fixed the memory leak in their roms (although I heard people claim this in cm12 also). Just out of curiosity can anyone confirm this is true?
I tried loading and swiping CoC 5 times and my free Ram still remains at 1200.
My battery life has definitely gotten significantly worse after 5.1. Drained over 20% in just an hour with very light usage.
Couple couple of things here:
1) I bought a nexus 6 from the Google Play store. I got a few updates since then and also rooted the phone. What I did not notice is the build number. The build number on my phone is: LYZ82J. I searched and found that this is a T-Mobile build. This is really strange because this is not a t-mobile phone. Although my carrier IS T-mobile.
2) The reason why I noticed the build number is this: I wanted to disable the forced encryption. My nexus is running EXTREMELY slow! Its just lags after lags. And I figured maybe disabling the encryption might help.
3) I tried everything to speed up the phone. At this exact moment I have 54.64GB of storage and 1.8 GB of ram Free on my device. I have uninstalled all of the third party apps that run on background, such as Facebook. Other than the root, everything else is completely stock on this phone. I do not have anything running in the background for things like Tasks, Launcher, Gestures, etc.
4) I ran a test on Geekbench 3. Every app was closed. And no third party app was running in the background and I got 774 for single core.
Questions:
1) Why do I have T-Mobile's build on my phone. And is this the reason that the phone is slow.
2) Why is my Pure Stock Nexus 6 so slow.
3) Can I download a factory image from Google's Website and Flash a Different build number on my phone?
3) If not, how can I disable encryption. And will it help speed up my phone?
Thank you so much for your answers in advance.
Mine also has random slow downs. I can't stand it, there's no way such a powerful device should stutter from time to time. I'm running the M3 preview, rooted, i don't think i'm encrypted.

Couple couple of things here:
1) I bought a nexus 6 from the Google Play store. I got a few updates since then and also rooted the phone. What I did not notice is the build number. The build number on my phone is: LYZ82J. I searched and found that this is a T-Mobile build. This is really strange because this is not a t-mobile phone. Although my carrier IS T-mobile.
2) The reason why I noticed the build number is this: I wanted to disable the forced encryption. My nexus is running EXTREMELY slow! Its just lags after lags. And I figured maybe disabling the encryption might help.
3) I tried everything to speed up the phone. At this exact moment I have 54.64GB of storage and 1.8 GB of ram Free on my device. I have uninstalled all of the third party apps that run on background, such as Facebook. Other than the root, everything else is completely stock on this phone. I do not have anything running in the background for things like Tasks, Launcher, Gestures, etc.
4) I ran a test on Geekbench 3. Every app was closed. And no third party app was running in the background and I got 774 for single core.
Questions:
1) Why do I have T-Mobile's build on my phone. And is this the reason that the phone is slow.
2) Why is my Pure Stock Nexus 6 so slow.
3) Can I download a factory image from Google's Website and Flash a Different build number on my phone?
3) If not, how can I disable encryption. And will it help speed up my phone?
Thank you so much for your answers in advance.

1. I don't know the logic behind the updates, but since your on t-mobile, the updates appear to pull toward your carrier. Doesn't seem to matter that you have non branded.
2. I have always found stock to be much slower than roms. I know it's a pain, but it does help to wipe the phone from time to time.
3. Yes
4. You have use a kernel that doesn't force encrypt, and do a complete wipe to get rid of the current encryption. i dont believe it will speed up the phone to any noticeable amount.
My suggestion would be to go with a well made ROM (there are plenty).
I suggest Pure nexus ROM with hells kernel.
It will give you a stockish feel without all the stock lag.
My geekbench below, running pure and hells.
OTA builds are decided by your sim. T-Mobile sim get T-Mobile build.
Geekbench score running JDX 3.0.4. http://forum.xda-developers.com/nexus-6/development/rom-jdx-1-0-t3121053
im glad that i was off today, from both work and xda. otherwise, id explain about whatever you ask..
I get a pretty good score running stock and always have. Maybe try reflashing a factory image and start over?

are you running a custom kernel or completely stock? if completely stock, do yoj mess with your cpu at all?

I'm completely stock by manually flashing the image files one by one from the Google factory images page. No custom kernel or CPU tweaking. I did root and decrypt using WugFresh NRT.
EDIT: I guess decryption requires a custom kernel technically...
Always remember, those benchmarks mean nothing. the benchmark scores can easily be manipulated by the software optimization and a little system tweaks. A phone with 4 cores can get a higher score than a phone with 6 cores thanks to the system tweaks (in android particularly done in build.prop) and better software optimization. So for me benchmarks are nothing more than a little estimate and their value doesn't mean anything in the practical world.
And if you want to keep your phone upto date without any issues,you should download the nexus 6 toolkit, its the best thing to restore your phone whenever it gets bricked. It's a simple click procedure with one click rooting to boot loader unlocking, try it.

Mine slows to a crawl from time to time, event the soft buttons not responding to touch for several seconds. The boot animation is similarly slow.
It's always been like this as far as I can remember. I am running CM 12.1 nightlies, encrypted.
I guess it depends on your definition of slow. I am just running plain Old stock rooted 5.1.1 encrypted and my device is fast and smooth.
I would suggest wiping the phone and starting over from stock.
Yeah I would wipe and start from scratch. In addition, I would force fstrim on /data and fsck /data /system and/cache.

I never notice any lag on my nexus 6, its stock on page plus. I have no issues with this phone at all. My moto x pure that I had was a laggy turd, I traded it for a nexus 6
I bought my N6 about a month ago, it was running 5.0.1 during the setup it went through 6 updates until it was on 5.1.1 and build was LMY48M and it's lightning fast. I'm also on Fi network with no problems. Maybe your sim card is bad or carrier is slow. You might want to flash the latest build and a new sim.
Good Luck

Removing encryption will definitely speed up your phone without reducing battery performance (maybe even improving it).
I'm using N6Shamu Rom with LeanKernel and find a nice balance of performance and battery life.
If you just want performance try Pure Nexus Rom
My Nexus 6 slows down a lot also. I ran geekbench 3 and was getting 700s for single core, well below avg.
This seems to happen after getting a bit warm. If I run geekbench about 2-3 times, the phone starts slowing down a lot. I'm thinking I have a hardware issue.
But other times the phone is buttery smooth as are high demanding games. Who knows.
So I got my nexus 6 last black Friday. I have mainly been running pure nexus since then. My issues with it are many.
Terrible battery life. I'm running greenify, tasker, amplify, and better battery stats. I have improved it somewhat but I would like to know I can get a day out if it. I am not a heavy user at all. I'm at 35% an hour right now but can get it down to 8-11%. The is screen off and not many wakelocks reported. Smh.
It is laggy as hell. Chrome takes a while loading websites, keyboard takes a while coming up and sometimes doesn't come up.
I'm running elite kernal at the moment with interactive governor. I also have xposed installed with a few apps.
Can anyone give me some advice?
ok so i would backup whatever needs backing up, flash back to the latest factory image and then see if the phone acts the same.
If it is still this abomination that you describe then get it replaced/warranty.
Try that report back, good luck im interested in the outcome.
I'd go with Skinpipe's advice. But don't load all those apps back on when you test. I'd bet you have an app gone rogue with wake locks or maybe kernel issues. Anyway with a fresh new factory image - and none of your current apps, you'll know.
Thanks I will try that and report back.

Stock unfortunately runs like crap no matter what I tried the closest I came to Nexus 5 smoothness was stock + Elite kernel with Blu-active CPU governor. battery was still kinda crap though.
If you really want smooth I'd recommend Pure Nexus rom + elite kernel w/ blu active. <-- This is that kind of combo where you actually follow instructions and make a backup of before every update because it's so good.

you do realize that "so good" depends on the user? and your so good can be my terrible. I guess I'm better off, because I can use any custom kernel, change up how the CPU works, and become happy instantly. I'd even recommend the op to learn about governors and schedulers, what they do, and how to adjust them and everything that goes with them. I also use pure nexus BTW, but with despair kernel. despair kernel because its extremely easy to get what you want out if your CPU with it.
Thanks for all the help. I reflashed stock N and ran it for a few days. Now I'm on stock N by rocketpanda and it running 1000x better. Battery life has greatly improved. I get close to a full day now maybe even more but I have only been using it lightly. It is snappier. I put on Nova launcher but I think stock launcher was snappier. I did have to up the min CPU freq because it wasn't waking from screen off correctly. Battery life still good though. I also clean installed all apps and left off a few that I use and will just keep those on my tablet (Bluetooth apps)
One quirk is keyboard popping up slow at times. I disabled the option of letter pop-up but still acts up.
Other issues I think are app/N specific. Google play games won't log into my account. Chrome still loads slow. Bluetooth won't always turn on after turning off.
I will look into governors since it is not as fast as my old note 3. I think there is some room for improvement.
Right now I'm happy though. Don't know how much of a fan I am of preview N since still figuring it out. I have no xposed install which is fine. I am off work next week so may try going back to PN.

good to hear you sorted it out a factory reset will always do the trick
