Microlag? - Zuk Z1 Q&A, Help & Troubleshooting

I got this phone last week but as I started using it, I experienced some lag in the home screen and in the menu, I looked on running apps but nothing special. Is it a bug?

Probably a bug, mine's fastest than my fully optimized/customized Nexus 4
The only "lag" I have is when I try to wake the phone from a deep sleep, sometimes it takes 2 or 3 button press :/ (but I hope that it'll be fixed in a future update since it's only a software/kernel issue)

I've got the same problem when I try to wake up my phone sometimes.

Yep, same here.

This is nothing new. The Snapdragon 801 go in deep sleep and need about 2 sec to leaf 300 MHz to +800 MHz. After that no lags...
On the other side I lose after 10h stand-by about 7-8% battery with anything on.

I noticed more or less the same battery drain issue at night! Any idea why?!

Is it an issue? I don't think it is!?

Galaxy note update notification 26th July

Hi
This morning 26th on my note I had an OTA notification. Since I had no Wifi, I cancelled it. Now, when I do a manual check, it says 'no updates available'. I already have 4.04 (XXLRG) from an update a couple of weeks ago so it wasn't that.
Any idea what it might have been?
Hoping for some Jelly Bean soon since I like it on my N7.

Omg. Seriously hoping this is foreshadowing the release of jellybean for the note...
Come on Sammy!!
Most likely not jb but to remove search the phone capability

Pah!, it was just XXLRK, 4.04. It installed a load of rubbish without asking (all German due to CSC setting).

Installing that much (really, any!) crapware along with updates is not cool...
But give me Jelly Bean quickly and I'll forgive you, Samsung.
So. Anyone know if this update fixed the battery problem many have? And fixed the issue of bricking the phone when hard reset?

The OP just said that all it did was install a bunch of crapware.
Nothing else.
And it's improved the performance..

Now now....can't use this without "value added software" because your user experience won't be as good
I got this update yesterday. However I can't find the apps mantioned here. It only said "Improved performance". I don't know what they mean. I have had the problems with the battery. I had to either pull the battery for a minute or two, or I had to switch on power saving mode right after charging and leave it on for some minutes before turning off powersaving. I had to do this every time I charged the phone, or else it would not go into deep sleep. It would stay on 200MHz, and drain the battery in a matter of hours.
However, this morning I saw (using CPU Spy) that the phone had charged all night using 200MHz (this might be normal. I don't know this). I tryed to just pull the charger, without doing the steps mentioned above. And i see now, a couple of hours later, that the phone has gone into deep sleep since I pulled the charger.
It might be too early to draw conclutions on this, but it looks promising so far.
I have found no info about the update yesterday. I hope its possible to hard reset the phone without bricking it now, but I don't know.
I will keep monitoring the phone, and let you know.

IIRC the phone doesn't charge during deep sleep, so clocked at 200 while charging should be normal.

That is normal and always was.
After you pull the charger it takes few minutes and the note goes into deep sleep.

I explained badly I think. I have used the CPU Spy for some time now, and i have seen that the cpu use 200MHz when it charging. Good to know this is normal. The big difference this morning was that when I took the phone off the charger, it went into deep sleep. It hasn't done that for a long time. Before the update, it went on using 200MHz after charging, when it was supposed to go into deep sleep. The only thing I could do to get it into deep sleep, was to pull the battery og use battery saver for a few mins.
I just hope they have fixed the brick problem when doing a hard reset too!

Yehh. I asked customer support what the update was, and if they fixed the battery problem and brick problem. They answered that I had to hard reset to fix the battery problem and the update was "improved performance". So I guess I either have to live with a bad battery or bricked phone hehe. Kinda hopeless imo. Anyways, the battery still works good after update :good:

Battery drain even in deep sleep

Hello folks,
I'm facing a battery drain problem when the Tablet is idle. In the last week i managed to get >11h Screen on Time and awesome idle battery stats. But now my battery drains even if the device is in Deepsleep with Wlan on and Synch on (>97%) about 1-2% per hour. [With Gnow off, Bluetooth / GPS / NFC off). The curios thing is, it happens with all Roms I tested so far, when I'm replacing the stock kernel of the rom with the ktmanta Kernel.
Can you guys give me an advice ? If there were wakelocks which wake the Device i would know what to do, but with Deepsleep > 97% ? The only Wakelocks are gmail and google account synch.
I would be thankful for every Hint.
Best regards

This most likely and issue with the kernel. If your kernel supports underclocking you should consider doing that because underclocking uses less battery. With all that stuff off and ONLY wifi on, during sleep you should not lose more than a percent every couple of hours. I have kept mine stock but im well aware that most battery issues are relating the kernel. I have a nexus 4 and Gnex before that both rooted and used to run AOKP before but not CM 10.1. So I have seen enough battery issues to kno that this completely because of the kernel.
AW: Battery drain even in deep sleep
Okay, I'm aware that it has something to do with the custom kernel. But the weird thing is, that all was good and then suddenly after 3-4 cycles my N10 started to lose battery in Deepsleep. There wasn't any change in the rom / kernel or settings. If tried several Roms / kernels but only get rid of it, when I stick to cm stock kernel.
Atm I'm on the actual ktmanta underclocked @ 200-1400mhz + undervolted

If it is happening with every custom rom you have tried so far then maybe it is time you try a new kernel. Also, this might not be it but just to be on the safe side, check what apps you have running in the background. Might help.

Battery acting weird

Battery actine weird
When I go to sleep I put my N4 on AC charging, when I wake up my phone is on 100%, and here starts the issue.
Then I start using my phone, and it goes from 100% to 99%, and after some time again to 100%, and few more times like that and then it goes to 99%, 98% and normally starts to drain.
Does anyone experienced this issue, bug?
Don't worry about it. It's a known bug since the dawn of time. Let's hope Google fixes this in the next update.

There will be no fix!
It is no bug, it is just for security to prevent the battery from overcharging.
It goes to 99% then up to 100% and down to 99%....
It is just a number, you know?

I believe the OP may be referring to this behaviour which is also "Nexus 4 normal".

[Q] How to fix strange battery behavior?

Since last week I am experiencing a really strange behavior of my battery.
Sometimes my phone (in a random app) just vibrates, the screen goes black and then it reboots. After the reboot I have lost 40-50% battery life. Sometimes the phones isn't even able to complete the reboot because it spontaneously has too little power left. See attached screenshots.
Has anybody had similar problems? Or knows a solution?
About my setup: The problem seems to be not rom or kernel related. It occurs no matter what rom or kernel setting I am using. Currently I am running coool boy's 4.3 GE witch KT's kernel (no OC or UV).
Is it possible that the battery is physically damaged? I have NO IDEA...
Experiencing the same problem. I've flashed back to stock and still experiencing this. Phone randomly turning off, not starting, sudden battery drops. Driving me crazy.

Consider buying a new recovery
HITTTTTTT THANNNKKKKSSS
galaxy star duos ****rooted*** xda offical app ) )
I've seen the same sort of graph on my old i9000. You're not gonna like this, but it got worse over time, and eventually my battery wouldn't last more than 5 mins. I thought buying a new battery would help, but it didn't. When I sent it in to Samsung they said they would have to replace the entire motherboard...
I think it's got something to do with the motherboard not being able to correctly sense the battery voltage/whatever/%. The phone reboots automatically because it thinks the battery is flat (even though it isn't).
If you're under warranty I suggest sending it in soon... Hopefully it's not the same as what I had heh.

Well *#!$
I'll observate it for the next few days and see if it's getting worse...
If your phone is rebooting as opposed to just powering off, then I suspect it is hardware related (motherboard) as already mentioned.
I do hope I'm wrong though.
Maybe try using it for extended periods while plugged into a charger and see what happens. If it doesn't reboot then it may just be the battery.
Right as OP I'm suffering the same exact problem or there abouts. I've flashed back to stock rom, fully charged to 100% drained to 0% back to 100% yet still phone keeps shutting off randomly and the only way it works properly is with the charger plugged in. It's escalated quite badly with now after a few mins of YouTube turning itself off and not rebooting. I've requested a repair by o2 who I'm in contract with and see what will happen. I've heard crap stories about their repairs before taking it to Samsung.
I9500 owner. Had this exact same problem when using older firmware. After updating to the latest one, never had this issue again. Its been two months now, even more.
Try this. Flash the latest available firmware for you phone, not talking about OTA but the downloadable one from any region (whichever is latest for i9505). I guess it may have something to do with the kernel too.
Edit: wait a minute, why is your battery level going up when it isn't even charging in the second screenshot. Middle of the battery timeline. That's weird. I guess you should send the phone back

Thank you guys :good:
In the last few days the problem occurred more often. But now it is just shutting down (no reboot after vibrate) and after plugging it to the charger and restarting it sometimes I haven't lost any battery. Strange!
I fear there is nothing else to do than turning it in (warranty)

Same problem here. It started three days ago and today I'm barely able to use it... I'm still on warraty and I even have insurance, but it's a major inconvenience anyway.
Mines gone in for repair back to my carrier still no movement despite them having it for 2 days now really should have sent it back to Samsung directly. Will keep you guys posted.

Hey
I am new here.
but i was looking for information becuase my s4 9505i has the same problem
shuts of almost everytime i open apps too quickly or stream youtube or some other high usage apps etc.
battery drops up to 50 percent then back 40 percent then to 0 percent, the fact it that the phone never seems to know where the battery is.
by the way my phone is not rooted and i have done the factory reset a few times.
samsung... hmmm.. they seem to be real hard to talk to on the phone, i have had to call them 4 times already about the s4 i ahve had since june, and they just play me off like i am some kind of idiot etc. and deny that there is possibly any reason for random shutdowns, phone freezing, and now this battery/motherboard issue.
next bit is kinda stupid, the phone has a few internal scratches on it from when i ahve stupidly had the phone next to keys and all that. im sure they are going to try and void my warranty and say i have mistreated the phone...
had many phones before, maybe close to 50 and never, never, never have had to ring up a company to try and complain etc.....
any ideas.
I am in Australia,
I am thinking of trying the CONSUMER AFFAIRS kind of threats, but i have to word it the right way...

If you are experiencing wake up lag when you press the home button, try disable s voice double press home button detection from the s voice settings.

this issue is in every galaxy, because when the phone in deep sleep it runs at 200mhz and when you wanna wake it up it needs to run at higher speed this is the reason it takes longer, it needs more time to speed up...

It's really annoying but I'm getting used to it.
My exynos variant does not suffer from any lag whatsoever
Samsung wouldn't replace my phone as wake up lag isn't covered by Warranty.
I have exactly the same problem however my lag is 1s at most.
I have tried everything from going back to stock rom, stock kernel, unrooted (all this using odin).
My friend has the exact same phone and it doesn't do it, so I would say it is a defect from Samsung's part.
There's an app called "Wake Lock" in the appstore which you can enable "partial wakelock" and you'll get instantaneous wake screen (basically makes sure one of the cpu core is running at least at 200mhz).
I am not sure what the impact on the battery yet, so I am testing it out. I'll get back to you when I have some data.
Yes, I also see the lag.
And there are also lags when I press the "recent apps" button.
Dispointed... not sure it's Android's problem or just Samsung
I have this issue too.Same boring Samsung problems every year in any flagship
I had a microsd card in my phone. I removed it and no more lag!

I had this problem for months and tried everything, it's the microSD card. Turn it off, pull the card, start up, and your phone is back to its own self! I cleared my cache too, but I always do that. I hope this works for everyone as well as it did for me!
