Probably too many apps or widgets in the background running eating the memory and cpu power. Install BetterBatteryStatts and Cpu Spy for app behaviour and deep sleep.

I will try, but i kill app every time when i want so screen off.
Limit background processes to 4 in the developer options. Let us know if it still persists. My gti9500 has never lagged, its now on its 3rd week with me.

Hi guys, just bought S4 I9500 5 days ago and yesterday i just noticed 1-2 second delay / lag when waking up sceen with power / home button
I know this has ben issue since S1 because i have Galaxy Gio and Galaxy Ace. Both have this issue after updating in GB. no wake up lag in Froyo. and i know this also happen in lot of Samsung Phone (S2, S3, Epic, Note 1,2). But the difference is those phone already do that from the start, but in my first 3 day i think don't have the issue (or i don't know, maybe i just too amazed by Full HD 441ppi screen and not noticed it until yesterday)
what i want to ask is that do u have this issue on ur S4 too?
because when i googled "Galaxy S4 wake up lag" the result is direct me to S2,S3 forum /article, even Epic 4G. but nothing about S4. I just afraid that this problem is specific to my device / i have a fault device
I already tried:
-. turning off all S-Voice setting and even disabled the S- voice
-. remove SD Card (because some people on S2 thread say that the device need time to mount SD card everytime screen on)
-. wipe dalvik from recovery
none of them works
i know the problem is caused by SOC that go to deep sleep to save battery because:
-. if i turn off and instantly turn on again, the lag didn't happen (because the processor still wake. ussualy take 3 second to go to deep sleep)
-. playing music / downloading someting /do anything that run in background. the lag didn't happen too (because processor awake to do all the task)
-. use app like wakelock and softlocker that make processor always run even screen is off. but this drain battery very fast because the processor is forced to awkae 24/7
please tell me do ur S4 have this issue? because 2 point below make me afraid
1. i feel i didn't have the problem for the first 3 days (but it can be that i just did not notice it yet)
2. i find bunch google result about this problem on another Samsung device, but none mention S4
thx b4
no one have this problem?

As you mentioned starting Android GB, the deep sleep was introduced, hence the lag when waking up the device, this was put there to save battery.

Have you tried opening S-Voice, hitting the menu button and turning off the 'activate S Voice with double tap of home button' option?

AFAIK, that's just an issue with the wakeup time of the exynos processor. I had this exact issue on my s3 ( with the exynos processor) and it bugged the life outta me. Since buying the snapdragon 600 version of the s4 the lag is nonexistent.
So it's not exactly a problem. But is certainly annoying.

yes, i heard about that too. from the start i also want to buy i9505 but my country only get i9500
what surprise me is that few days ago i have a family meeting and when i played with my cousin's S3 (exynos, stock 4.1.2, no root) there is no wake up delay. the screen wake up instantly. even my finger is still on power button when the screen wake up.
i know a lot of people have this issue in 4.0.4 S3. so this means that the wke up delay can be fixed by firmware update? (like 4.0.4 to 4.1.2 in S3). i dont know about my cousin's S3 pre-4.1.2 because she just bought it recently this year and already have 4.1.2 out of the box
anyway thx for the replies
galaxy s4 2 second delay wake up
i have also thid problem and its killing me plz help me:crying:
I have a version of the i9505 Android 4.2 and the problem did not occur, but after the upgrade to 4.3 the problem occurs: (
Also looking for solutions ...
Hey all,
I recently noticed the weird core usage of my I9505. Sometimes when I start up the phone, all core are active at the lowest frequence (even when I'm texting or something). Even after for example, a half hour deep sleep. And when I restart it, it's just using one core (when I'm just texting or something), sometimes a second, but then it goes back to using one core. Also, if it's all looking good, it can suddenly start to use 2 cores and never go back to using one. Even through and after deep sleep.
I'm running 4.3 XXUEMI8. Anyone knows if this is normal?
greetz,
swa100
By the way: I'm using greenify, so no bull**** apps are running in the background. I've also deleted all the bloatware. And sync is disabled.
I have a SM N900 Exynos running android 4.4.2 factory non rooted device.
I have bought it from an authorised samsung dealer not even 3 months ago.
I have noticed the phone freezing under load, like i had 4 downloads open on UC browser each of 200mb and was listening to songs via earphones on the native music player also had musixmatch open. At this stage my phone became very hard to control kept on lagging to a great extent till the point i pulled down the notification bar and system ui stopped responding and screen went off and only the capacitive keys were lighting upon touch, no haptic feedback. I had to restart my phone.
I have noticed this a lot whenever i have a lot of things going on, well this is an octacore device with 3gb ram. This shouldnt happen ever. It should be responsive all the time.
Also if i open a few number of apps and press the home button to go back to the main screen, the phone starts lagging. Shouldnt the memory management be good like the phone closes the unused applications by itself whenever ram is low instead of me going to recent apps and clearing some of them to regain performance.
Anyways i have some 128 apps in appdrawer including the system apps if thats any help.
Thanks in advance any help would be greatly appreciated.

The device comes with 3GB of RAM not all available to the user. First of all you have an Exynos device so you have 2.7gb RAM. I believe that they opted for a bigger RAM choice for the system to handle itself excluding user input.
So essentially you have half of the RAM to use for your other applications (1.35gb).
Anyways, have you tried clearing tasks in Task Manager? Stopped junk apps from wasting start up memory? If you have, then you really should reflash stock or Factory wipe, in order to see which apps you reinstall to prevent unnecessary slowdowns.
Are you using power saving mode while multitasking?? if yes then turn it off and try again, another tip is that phone are like mini laptops without fans they need to rest from time to time, so try to restart the phone or shut it off for few min, then test again, good luck.

Yeah you should check for this too ^^ (sorry not trying to tell the quoter but I have more to say)
I have over 650 applications installed (including system) and have no problem with lag, I even have Hyper fluency enabled on my launcher which makes it use double the amount of recommended RAM to make it look and feel better. No lag.

My phone runs good without lag, but after opening a good number of apps it slows down. Then i have to manually open multitasking(holding the home button) and swipe away a few apps. Shouldnt the phone automatically exit some apps when running low on ram?
Well as far as i know no one exits apps after using them, after they are done using a app nearly everyone uses the home button instead of exiting the app.
And no, no powersaving mode is enabled.

Just last month, a friend of mine had a problem similar to this: the phone responds to button press but there is specific period of time that the screen won’t respond. We ended up replacing the digitizer. It is a piece of glass on top of the display panel that conducts touch commands. Digitizers come with their respective circuits that when messed up, some, if not all, screen functions won’t work. But it seems that your problem is not the digitizer, so try booting to Safe Mode and observe the phone’s performance while in there.
If the screen still freezes randomly, some of the core functions may be causing the problem and there’s no other option but to perform factory reset but first, back up all your data.

Since i bought the phone in around 4 months the phone has frozen under extreme load only twice. Would you still recommend a a factory reset?
I observed that if a lot of apps are running in the background and phone starts lagging, I just swipe away a few apps from the multitasking area and everything works fine thereafter.

I have a rooted GS5 on verizon running 5.0 and it's very slow. Its seems that the task manager isn't doing much, when i have a lot of apps open, the phone is almost unusable. Sometimes when I'm navigating using google maps, the navigation will just quit with no notice, same with google music.
if i open the task manager and "close all" the phone will run quicker for a bit, but then it just slows down again. it's very frustrating.
Something that has just started to happen is the screen will come on after i sleep the phone. I have no idea what is causing it, but the screen will just come on for apparently no reason. I have recently reset the phone to factory (when i rooted for 5.0).
Are there any apps that will tell me what is causing the slow down? a task manager that will track CPU/ram usage? and is there an app that will tell me what is causing the screen to come on? I'm about to do a factory reset and not root cuz the phone is unusable.
Thanks.

Unless you have a custom rom/kernel root will not affect battery.
There are many battery statistics apps on play store, i would personally recommend GSAM Battery Monitor.
Battery isn't really the issue. The phone just gets Bogged down easily.

Tnx but I have done factory reset several times and the problem still remains
Will high speed micro sd really helpful?
Of course if microsd card speed is low then it effects the device and processor need to do hard work to run everything smooth and lot of data of apps and games saved in microsd card.
Try a new battery.

Overall note 4 always heat a lot because 2k 1440p scrern so don't worry
Try deep black wallpaper this will help save battery and gpu.
Try greenery to hibernate apps
Disable apps you don't use
Root device and Uninstall bloatware apps
Don't ever use junk or ram cleaner apps like clean master
OR even battery saver apps this apps murder the processor..
Don't kill apps by swiping them from recents that you use more often so processor don't need to run wake them again
More your processor sleep the device will run smoothly and no heating.

I've done most of those solutions(except those need root)but they didn't make sense.
Before marshmellow I didn't have this problem and everythings were perfect but after the update...??
when did it start?
what part gets hot?
is there something specific you're doing when this happens?

The center and right part of back start to heating after several minutes all of the phone gets hot.
Mostly chatting or web surfing and some times gaming but the problem is ,it gets hot even listening music or other light works.
that could be very bad.
that's where all the power management and usb related chips are located.
it might require a new motherboard.
I was kinda hoping you had the same problem as me, which is heating just below the camera which is caused by "wifi scanning" going haywire(Wi-Fi toggles blinking on/off while Wi-Fi is off)

Go to settings/battery/details and make all apps to always save power
This will help in marshmallow for doze mode and make apps deep sleep while not using device and not let them run in background..
