[Galaxy Note 4 General] tmac31:
There is memory leak on s6. 85% of ram is on use all the time. Its very bad experience. We should see it without leak. But im not expecting way better experience since without leak(after restart) phone still use 2gb of ram every time. And everything kicks out of ram too much. My note 4 use around 1.7gb with same usage but stays there s6 just goes over 2.3 gb without any app. And app switches too slow compared to note 4 from multitasking screen.

And windows and ios is just different. Dont compare it. But i can add something iphones has great hardware they dont have outdated cpus. They just have less ram and with everything kicks out of ram after 2 app is big headache.

Yes and if you have alot of apps opened it lags.
[Galaxy Note 4 General] Life Engineer:
Well how on earth your note 4 stays on 1.7gb!?!?

Mine stays around 2.3 to 2.4 from 2.77gb available on N910C exynos version!

This is on custom lollipop rom debloated and already many apps and S-apps disabled!
[Galaxy Note 4 General] Batfink33:
I'm not saying the Samsung phones haven't got RAM problems but in general the way Android uses RAM is different to the way Windows uses it. Android fills up its RAM as you open apps and leaves them in it until you run out of space and then it automatically closes them. Technically when you look at Androids RAM usage it should be high as the apps will be sitting in it waiting to be reopened when you multitask. The problem comes when you have RAM leaking and be used up by these leaks, then you don't have enough RAM for new apps to sit in and the older apps are force closed and you get redraws and slower load times as the apps have to fully restart.
[Galaxy Note 4 General] tmac31:
well yes and no. samsung phones use alot of ram in idle. htc nexus sony phones just use around 800 mb while samsung devices use 1.7-1.8 and it makes problems like reducing multitasking capabilities etc. leak is totaly different thing and note 4 doesnt have it.

---------- Post added at 01:52 PM ---------- Previous post was at 01:52 PM ----------

dunno im running a fully stock rom with disabled useless stuff.
[Galaxy Note 4 General] Batfink33:
Yeah they do use a lot in idle. I saw similar issues in G3 which was over 2GB in idle and the Z2 which was similar to the N4. I think you're looking at Nexus devices with no bloat if you want low Ram bloat without freezing etc. Anyone know what Cyanogenmod on the Note 4 uses in idle? Technically that should be running low but I can't remember from when I had it on my phone.
[Galaxy Note 4 General] tmac31:
well my girlfriend had z3 and it was using 800 mb in idle and now she uses m9 and it uses around 800 mb too. their usage ofc goes higher if you dont restart them like any other android phone but atleast they start getting high from 800 mb but samsung devices start from 1.7 etc. and my s6 just uses 2gb after fresh restart.
[Galaxy Note 4 General] Batfink33:
There is far too much bloat in TW Roms no doubt, they're horrible. Now that Samsung are getting their act together in the hardware dept they need to sort out their software.
[Galaxy Note 4 General] zkyevolved:
And why shouldn't we compare them? All you see on the net is how Windows Phone has the app gap... Compared to...? Android and iOS. All you see are reviews iPhone 6+ vs <flagship here>. I think if we can compare any of those devices to Android, we should also do so here as well.

All I was saying to begin with is that we are in this HUGE race to get AWESOMELY specked phones on Android when if all we need are optimizations we could get awesomely fast devices like on Windows Phone which run perfectly on SD 400 processors and iOS with 1GB of ram. And here we are on Android worrying about SD 810 vs 808 vs 805 vs 801... Our Note 4 is slower than my partners Xperia Z Ultra in multitasking. A device that is 2 years old with a SD 800 processor and 1GB less of ram... All this says to me is that Sony is taking care of their devices while Samsung is not. Windows Phone devices run SOOO smoothly! I had both the 930 and 1520. Awesome devices. Great OS. But Windows Phone is not for me...

I really don't see any problems in comparing any mobile OS. They're all fair game to test, use, buy and compare. So ... that's what I did here. I just wanted to point out that we don't need SD 805 processors if Samsung were better optimizing and spending more time on their builds for us. Instead, I have a 2013 device right next to me that offers a much smoother experience than my 2014 device that has better specs in every way possible.
[Galaxy Note 4 General] Life Engineer:
I completely agree with every word you're saying!

You can see in my signature that I've had many android phones and my experience has never been fully satisfying with any of them, especially with the latest flagships!

I'm not gonna tackle the hardware issues bcz it's device specific but I'm gonna say that android is pretty much an issue by itself and I've come to this conclusion after all these years! Yes it is maybe the most powerful in its potential and it's maybe the most capable and functional... But it's never the most stable or the most consistent or the smoother!

Battery life is completely unpredictable... sometimes something gets stuck in sync, sometimes google play services eat the whole battery, sometimes a wakelock etc... it's really a bad experience! I've never owned an iphone but judging from my ipad, iOS looks so consistent in that regards!

I promised myself the note 3 would be the last samsung i get bcz it had like 2.3 to 2.5gb of ram full everytime anytime even with debloated roms! That's completely unacceptable! And please nobody say "free ram is wasted ram" bcz if the ram is occupied by samsung/google stuff without leaving anything for the user, then that's the real waste!!!

Once my oneplus one failed on me, I got the note 4 bcz it looked the only real upgrade from it! Anything else seemed less than the oneplus one!

However I thought samsung may have fixed it but hell no! It's still the same! and battery life on lollipop sucks!

I may get a nexus 6 or 7 or even give up on android and try the iphone!

Right now I'm pretty sure that android is powerful but really unstable and unpredictable... That's sad but true!
[Galaxy Note 4 General] kolembo:
My note 4 rocks.
[Galaxy Note 4 General] tmac31:
i said dont compare them specwise.... im an ios user too so i know what it can do. but its using awesome specs its not running on an old hardware. its just using 1gb ram but it doesnt mean its super efficent just it does t have multitasking my 6 plus kills everyrhing in background its a big problem. and 6 plus has stutters, crashes, lag on call screen etc dunno how long you used ios devices but im using them since ios 1 and 1st gen ipod touch came out. its not perfect as you think.

and about wp i just used 1020 it can be smooth etc but it was 1 of my worst experience. after 2 months apps got stuck on updating they were downloading always from store but never managed to update their self. so same app were trying to download 7/24 i wont ever buy a wp phone its was totaly fail for me.

s6 is huge fail too.

i used htc m7 and nexus 5 i know samsung sucks lol i didnt say anyrhing about samsung dunno why you answered that way. but comparing totally different os over hardware is bull**** sorry. samsung s own fail doesnt make whole android problematic cuz my 3 year old nexus 4 runs great and smooth. and im happy with my note 4 910c too its faster than my 6 plus more stable and gives great battery life (6 hours sot) i dont know why people think 5.0 update is bad for note 4 but i have atleast 5 note 4 user around me and all happy about it. yes we all dont play games so gpu bug doesnt effect us but only problem is delay kn call screen for me.

so no you can think every other device runs super instead of yours but just no. i can take htc software with note 4 hardware over any phone thats for sure. but all i have is this and i used z3,m9, and still using s6 edge, 6plus , note 4 exynos and still think its best device out there with 6 plus since s6 edge is complete disaster for me.
[Galaxy Note 4 General] Clippernote:
My phone just asked me to update to lollipop and getting worried its going to **** it up I can't find anyones review of the official update with experiences, seems to be either part rom builds or custom versions?

I'll report back the update is huge (1223.79MB) sounds resource hugging to me LOL!

It's been fine for me.

I'd you can't find reviews on it, that's generally a good sign
[Galaxy Note 4 General] Artoriuz:
Android frees RAM as needed, you can pretty much run >ALL< your apps at the same time at 3GB phone and it'll be consuming almost the same as if there weren't anything...
[Galaxy Note 4 General] tmac31:
Yes it will free the ram for your app on the screen but no you cant run everything in the same time unless you are using multiwindow or popup view. If you are just open 1 app and swicth 1by 1 it will start kicking your apps from ram 1st so it makes bad multitasking. Like on my s6 it generally allows 1 app only after 2nd or 3rd app it just kicks your app from memory 1st. So high ram usage is problem. If you are heavy multitasker.
[Galaxy Note 4 General] Artoriuz:
Nah, I leave pretty much Whatsapp, Facebook, Messenger, the ridiculously buggy Gallery, 9gag, Wolfram Alpha, Chrome and other minor **** at the memory and it simply opens them instantly... Reloads are rare, and even the rare occasions when they happen, this damn phone takes half a second to reopen, so whatever...

Well, instantly if I press home button and then press the app button, the recents button lags if it hasn't been pressed in a while.
[Galaxy Note 4 General] tmac31:
Well they are small apps and note 4 isnt bad at multitasking but its bad compared to other phones with 3gb ram like m9 z3 etc. They can open way more apps. So no you cant open every app in same time like you said. Big apps like browser games etc will kicked out of ram soon. But yes its not that bad on note 4 atleast i generally have 5 apps open it does that easyly. But s6 edge fails to that for example or my old note 3. So every 3 gb ram phone cant open whatever you want its wrong.
[Galaxy Note 4 General] monkor:
Realistically speaking, Lollipop is fine for a daily driver. It's not obscenely buggy or disastrous fatal flaws. There are little things that annoy like home screen redraws and browser tab refreshes, and slight volume bugs. But I challenge anyone to go back to a Nexus 4 or 5 or even the 6 Plus (which I came from), and spend a week on it, then report your feelings back on the matter.

I still have all those devices around, and the Nexus 4 (crap battery, camera, and buggy), the Nexus 5 (crap battery, camera, and buggy), and the 6 Plus (buggy, constant reloads) help me appreciate the Note 4. Lollipop isn't perfect, but you show me a perfect experience on a phone and I'll show you a liar. There's always something, and 95% of the time the Note 4 is amazing (it is far from perfect, still).

In the meantime, we have a great community who does a great job squashing bugs with custom ROMs and kernels to supplement actual OEM updates 9 years later. Don't upgrade or do, your experience should be similar.
[Galaxy Note 4 General] zkyevolved:
I don't think anyone can say that the note 4 isn't awesome. It's a great phone that's very fast! But it's not without its issues that are mainly causes by Samsung. My partner has an Xperia Z Ultra, which is now an older device with less ram and slower processor. It's faster than my note 4! His cost 240 euros while mine cost over 600. I'm a teacher and some students come in with their far less expensive devices that have no issues loading recent apps or reviewing pictures quickly... Or worry about battery drain. I think Sony delivers a far better experience than Samsung on lesser hardware. That just proves it's not about hardware, it's also about software optimization. Samsung lunches far too many phones every year to take care of all the models. It's a shame. [emoji20] if these simple issues don't get fixed I'll return my note 4 and get something else. But... The note is an awesome phone. I just think for the money they're charging, it's too buggy. Not just buggy. Tooooooooo buggy. I have to monitor what apps are eating my battery every day! Most people don't have to do that on iOS windows phone or even some Android devices.
[Galaxy Note 4 General] tmac31:
1 question were you happy with phone when it was on kitkat?
[Galaxy Note 4 General] zkyevolved:
Can't say much. I only had it for a few days before the OTA update came. But I did have an issue with GPS lock issues in the camera. That was a horrible one. So I decided to stay with Lollipop, because at least I could use my camera and have it record where I was upon reviewing the images. Half of the time with KK it didn't record the location. What a shame :(.
[Galaxy Note 4 General] Batfink33:
You've got to remember also, the QHD the display is very power hungry and uses a lot of battery. A larger resolution device is naturally going to use a lot more battery and CPU/GPU cycles. The Note 4s panel is actually pretty power efficient and Samsung have done a lot of work on it. Newer phones also have more sensors and therefore use more battery and thus CPU cycles. As phones get and people demand more features then they'll lose more battery and be slower without the tech keeping up with them. The battery's we have today are still the same battery's we were using a few years ago but these days we demand more features from the phone so there's going to have to be a compromise.
[Galaxy Note 4 General] DJJacky2014:
snapdrgon devices or exynos devices?
[Galaxy Note 4 General] zkyevolved:
Oh, I couldn't agree more. But I actually lose less battery while using than while in standby xD haha. Hence the battery DRAIN. Something in the OS or Samsung's optimization is draining my battery while not in use. 0 battery is used by the screen, even if it were 4K or 8K while not in use... BTW I love the panel on this phone. The colors are incredible. Great looking screen :).

Hopefully Doze will help with the next android release since my drain is actually occurring while not using the device.
[Galaxy Note 4 General] tmac31:
i dont think so. your drain will probably be there, cuz im loosing 2% per night with sync on and mobile network. even background sync is on for twitter etc too. there is something wrong with your device cuz you say lollipop is too buggy and for me its definetly not. there is something wrong with your own apps i think.
[Galaxy Note 4 General] zkyevolved:
Normally I would agree. But I don't install many apps... So, it's highly unlikely... Plus, Android system is the "app" that uses the most battery.
[Galaxy Note 4 General] tmac31:
Its probably a setting you have drains battery i guess then cuz its not there for me while its there for on my s6 edge and i cant get rid of it. But its not my note 4.

Here is my battery usage today. Screen has around 1.5 hour and you can see standby is really good. And i have 2 mail twitter sync etc its my daily usage.

Ps:its stock device with disabled useless stuff and no power saving used.
[Galaxy Note 4 General] zkyevolved:
Nice. I wish I could get your stats! Here are all the apps I have installed.

I have 1 google account that syncs and another that doesnt sync anything (for all my apps). No facebook. No twitter. I do have 1 instagram account.
[Galaxy Note 4 General] tmac31:
Do you have google location report active maybe?
[Galaxy Note 4 General] zkyevolved:
Is this what you mean?
[Galaxy Note 4 General] tmac31:
Yes make 2nd option off atleast its off for me and location is on power saving
[Galaxy Note 4 General] zkyevolved:
I'll give that a try. [emoji1]

Other than that, isn't it confusing why my device is getting such a high battery drain?

Thanks.

Edit. I had to change it back due to the lack of Google Maps being accurate now. Shame [emoji20] .
[Galaxy Note 4 General] tmac31:
2nd 1 doesnt effect maps but 1st setting can effect it yes. Since i have navigation in my car i dont need it i generally switch high accuracy when im using it for running trainings only.
[Galaxy Note 4 General] avercros:
You are right.

I feel the same about my note 4, my mom has a moto e 2nd gen and that thing that is really cheap (150 usd unlocked) is faster in many ways like transitios, recent apps and scrolling, it's a shame that the note 4 with its powerful hardware feels slower than a moto e 2nd gen, i think that samsung need to work A LOT in its firmwares, also they are only focused in the new galaxy phones, they forgot completely the note series.

I'm a little bit disappointed with this phone because i was using a xperia z2 and that "old" phone was faster than my brand new note 4.

I'm just waiting for the 5.1.1 update to see if this phone perfoms better.
[Galaxy Note 4 General] Batfink33:
It always amazes me how devs on XDA can make kernels that are blindingly fast and improve the speed of a phone exponentially, yet stock kernels are generally slow and stuttery I'm happy with the performance of my phone but I'm running a custom optimised kernel. A custom kernel (and Rom) really helps with speed but you have to root for that which voids the warranty which isn't good for a lot of people. I do believe the QHD screen is causing a lot of slow down as well as the software though, the Note 4 is having to push a heck of a lot more pixels than the Moto E therefore performance will suffer quite a bit as the SOCs haven't improved sufficiently. I remember first getting the G3 which was running a QHD with an S801 and being really shocked by the performance of it.
[Galaxy Note 4 General] kolembo:
This is the main problem with lollipop - Memory management. In trying to make lollipop accessible to phones with less resources, is become more aggressive with what it kills in the background, which messes up with high end phones. On KitKat the problem is far less severe, so your going to need to be running upwards of 10apps simultaneously before RAM management interferes.

It's a big problem with Lollipop for me.

Here is an update.

[Galaxy Note 4 General] Romainlt:
Yeah very good new! It's the N910F like me, strongly it happens !
[Galaxy Note 4 General] Toss3:
Great news! Hopefully they will bring the 64-bit version to the public (that would certainly make porting the s6 rom easier)!

"We have, however, heard that Samsung could be testing a 64-bit build on the Note 4, though it’s something you should take with a pinch of salt especially since it might not actually make it into the final update as only the Exynos model has 64-bit support (which lies dormant.) " (Sammobile, 2015)
[Galaxy Note 4 General] benzxi:
i also hope that the camera feature for slow motion recording in lollipop gets fixed. 'twas better back in kitkat.
[Galaxy Note 4 General] NamelessFragger:
What I'm really hoping for are fixed Adreno graphics drivers; S805-based Note 4s have a GPU performance regression with Lollipop that impacts certain Gear VR apps, enough that Oculus deemed them unsuitable for purchase through the Note 4's Oculus Store (though you can circumvent this by editing the build.prop with the S6's model number).

The frame drops for the titles in question make it pretty obvious why they did that. Stuttering is not a pleasant experience.

I'm half-tempted to roll back to KitKat because of this, but this sort of update would be prime time for Samsung to get things patched up there.
[Galaxy Note 4 General] Mikael1711:
Software-wise, I think Samsung are doing pretty bad..... always disappoints me...... same with their smart TV's.
[Galaxy Note 4 General] Toss3:
The same is true for the Note 4 exynos; most Gear VR apps just don't run like they are supposed to. Guess we'll just have to move on to the S6 or Note 5 versions soon in order to get any support. Personally I'm considering waiting for the S7 as that one is supposed to be the first Galaxy S with Samsung's custom core SoC. ;)
[Galaxy Note 4 General] zuzulic:
I just hope that they will fix the menu recent apps incredible lag... :eek:
[Galaxy Note 4 General] zkyevolved:
And camera lag for reviewing images...
[Galaxy Note 4 General] barbudaniel20:
I am totally agree with that...is sick this lag on lollipop...and unfortunately we have no choice on note 4...kitkat have same problems ... :eek:
[Galaxy Note 4 General] NamelessFragger:
Wasn't aware of that; I just recall the developer docs and/or some of the VR Jam optimization posts pointing out the S805 Note 4 on Lollipop in particular had a nasty performance regression related to draw calls while suggesting the Exynos Note 4s were unaffected. Sure makes me wonder which SoC actually has the better GPU.

Then again, you NEED Lollipop on an Exynos Note 4 to use the Gear VR in the first place, from what I've read. Only Snapdragon models have the necessary services and software in their KitKat ROMs, if I had to guess, and thus that's the reference point they have for Gear VR performance on S805.

To be honest, I just got the Gear VR as a holdover for the Rift CV1 since I figured the higher-res screen would make for a better initial experience than the Note 3 screen in the DK2, and I'm actually rather surprised at how well it handles smooth head-tracking when optimized properly. Modern smartphones have come a long way, that's for sure.
[Galaxy Note 4 General] zkyevolved:
Since the S6 and S6E are getting 5.1.1 now, hopefully they'll focus on the Note 4... Hopefully...

[Galaxy Note 4 General] Toss3:
The Adreno 420 is undoubtedly the better GPU, but I assume it's easier to include optimisations in games for the Mali architecture considering it's ARM's own design, and that's why some games perform better on the Exynos 5433. It worked better under Kitkat, but you had to do some mods, so it's easier now on lollipop. I also doubt they are including any optimisations for the exynos version, as the snapdragon version was the only officially supported one.
[Galaxy Note 4 General] Batfink33:
Not sure why people are expecting wonders from 5.1.1, it's not that much different to 5.0. The M developer preview was much, much better than 5 or 5.1.
[Galaxy Note 4 General] gekkehenkie11:
Yeah the CM users have been on 5.1.1 for a long while already. Frankly I didnt think it was much of an improvement. But more interesting is the kernel, maybe Samsung made some nice optimizations there. Other than that indeed not interesting.
[Galaxy Note 4 General] one-option:
Truth always hard to believe.

Ok after Galaxy S6 5.1.1 update I don't think Samsung will offer much.

Samsung is busy with Tizen, new devices & updating like 1000 model with 10000000 region, this is too much for Samsung as I believe.

Today I Downgrade my Note 4 to Kitkat 4.4.4 ........... I will stop updating my Note 4, until the day Samsung will come with stable firmware with real update not only changing the theme & OS number.

Lollipop firmware for Samsung really missing so much features like Camera API 2, RAW support & Guest mode with other lag issues.

So why to keep waiting something Samsung could never bring ......?!

As for now I will be waiting for Microsoft Windows 10 Mobile & Apple iPhones ........... no more Samsung
[Galaxy Note 4 General] OnlinePredator:
CM 12.1 on Note 4 is incredibly fast compared to touchwiz. I prefer samsung's features but everytime I flash a "fast" custom touchwiz rom, I see lag all over the shop and doing simple things are so much slower.
