Hi all!
I bought my SGSII around January and already am noticing a big performance drop. It lags quite bad while watching videos, when listening to music it lags also, even something as small as unlocking it from the lock screen its quite laggy. My phone is not rooted at all and tbh would rather not until my warranty expires or until I don't care anymore lol. I also notice a high amount of RAM being used, I know that RAM not being used is a waste but to me this is unusually high; at the best of times I have around 150 MB free (~680MB used) going as low as having only ~50MB free.
Any suggestions on how to improve performance, anything short of rooting it, or any ideas on what could be causing such a drop in performance/high amount of RAM being used would be a great help!
Thanks in advance.
Root it, clear cache/Dalvik every now & then. If you're not rebooting regularly (say every day), try that if you don't want to root.
You could also back everything up to external SD/PC, format the internal SD card & reflash stock firmware via Odin.

Even running stock I never had more than 450-500mb of ram used. Should definitely root it to remove some bloat and run a custom rom

Haha I feel stupid now, rebooted and that cleared up a lot!! Im now using around 300 MB lol thanks!

could try format or just factory reset it to get rid of some old rubbish
my sgs1 started going slow so i did factory reset and was alot faster even after reinstalling my apps
I have a heat issue with any ICS based rom (official / custom), I almost tried all the ICS roms in xda-forum all of them make my phone like a small sun.
what can I do? is it a known issue? is there a fix?
Ensure full wipe; system. Data. Cache. Dalvik before flash.
Try a custom kernel such as siyahkernel or neak. Ensure no kernel CPU/GPU profiles are set.
BTW, using phone while charging will increase temperature significantly.
Also see what process is using your phone and what CPU frequency may be stuck.

Just flash any official ROM for your model. Do full wipe ( system, data & cache )
Once boot up , move all datas from internal & external Sd card to laptop.
Then format both the sd card.
let's observe one day
Remember dnt install any app

I have same problem when loading the phone, especially if the phone is in my bed under the pillow or anything else soft...
Battery Monitor shows temp capping at 75' celcius (!) and loadcurrent limited to allmost none...
But when phone is on the nighttable, the temps are considerably lower (47..57'c).
And the weird part is, that this never happened on GB roms
So my advice is to keep your phone free from any covering
I have this propsblem with my phone....it heats up while I'm texting or browsing the web. I have read the other threads but its mostly about phone heating up while charging or paying games
But I am not doing any of intense gaming or anything like that that requires lot of cpu power....
should I get it repair or is it normal?
Not normal .
Backup data and Factory reset first .

Thanks for the reply... I already did and its still the same thing.
it first stared when I updated it to ics... Then after I flash the miui rom same thing. Right now its in bell's version firmware (the one that came with the phone when I got it)
I am using the phone to reply now and I could already feel the heat from the back of the phone
r u full on ext sd scard or internal sd card??
did u use tb for bcking up an restoring???
does it wen u keep ur screen on (set screen time out at 10 mins) does it heat??
does it heat wen ur scrolling homepages for a long time??
r u on stock??which gb or ics ??

both storage arent full, i still have quite a few gb free
right now theres no apps installed except twitter and facebook
it only happens while im using my phone... im not sure about when the screen is off
it gets hot when i browsing internet
Stock GB 2.3.3 bell frimware
no custom kernel, on bell's stock kernel (which probably is the samsung stock kernel) before i was using siyah kernel 3.1.2 but it still gets hot on stock and custom kernels
thanks for reply

cause the cpu runs for reading media storage an if sometimes a faulty card gives a continuis run which heats up the phone ..

i thought it only runs once after booting up and then only when you add or delete files from sd card.
well i will try it and post back.
if a memory card is faulty, would the card still work?
EDIT: took out sd card and still gets hot.
thanks anyways
thanks to JJEgan
Did you try checking the temperature when it's hot? If yes, then how far it goes when it's really hot. I think 35 degrees is a normal mark.

download "temp+cpu" and monitor the temp
sent from S2
The main factors of phone heating, are Modem, Kernel, and Rom (but rom not so much)
When you don't have the proper modem, there have been complaints of overheating, i experienced it myself when i used the LPS modem, but since switching to my current one, i have had no problems
the kernel heating occurs when you UV or OC a custom kernel, that can be fixed by flashing a new kernel
Some roms might cause over heating, but very rarely, as roms are lighter then TW, and should be running less programs in the back ground
just some friendly advice, try flashing another modem
Cheers

Hello guys.. I'm a flashaholic.
The reason i'm here, is because i've just realized, that i haven't had my quick fix for some time now..
Everything seems so stable, except the *mic* issue, but hey, i fixed it with a hands-free.. Otherwise, i'm very happy with my phone, it works, it doesn't use up that much battery, and it doesn't crash, you can even do normal stuff to it.
But to the point.. I really, REALLY miss AOSP, especially the theming.
I can live with the occasional bugs, though i wish it could be at least somewhat stable.. *You know, im not that picky*.
But the one thing that keeps me from using AOSP; is the camera app from Sony, because i like taking pictures of my son, and the environment..
Are there any Camera app out there comparable to the Sony equivalent?
Oh, the urge..

I have the same urge, I wanna get the full output from my Xperia Z2, feel all those four cores working in my hand. But that one Sony Camera app stops me because it's beautiful. It's matchless. That's the only reason I'm not changing my ROM and be bound to what Sony's put in my phone.
I am in the same boat here! I want to flash PA so bad especially with all their features but then the camera app, the noise cancelling features and x-reality etc is really stopping me from doing so
i use to be in the same boat before i noticed there is no point to flashing roms when im on a rom which does what i want
perhaps you should find a rom which has what you want
Same here.I literally used to flash a new ROM on my Nexus 5 everyday. As has been said though, the stock Z2 ROM does everything I want it to and rooted with some xposed mods its perfect.I just have to learn to live with my phone the way most other people do.
just a note
formatting then writing a rom to your system slows your device ALOT, it also cause alot of other issues but that comes after long wear n tear

Does this include doing a clean install? I mean doing clean install also slows the system? I've done clean install (re-install the stock Sony Z2 ROM) for 3 times till now. (Via Sony PC Companion)

I remember reading somewhere years ago that flashing new firmware over and over will eventually wear out the hardware and cause it to slow down/eventually fail. I can't seem to find anything for this when searching though! Would it be possible for you to shed some light on what I should be searching for or what causes this issue?
Thanks in advance!

there is something called read/write cycle life
you can only write info so many times onto a disk before it wears out and stops working
formatting a partition takes a huge amount of cycles, installing roms does the same too because its alot of data that has to write

Cheers for the reply! From what I read on the link, it says most flash memory have a P/E cycle of around 100,000 and from what I can remember, it varies depending on the type/quality of the flash memory used (Nexus 7 2012 had rubbish flash memory which a lot of people complained about). Just going off an assumption that the Z2 has a P/E cycle of 100,000, wouldn't it take quite a lot of ROM flashes before the memory deteriorates? Or is it more due to the size of the data being written/erased than the amount of times it is being done?
Sorry for the questions, I know this isn't the thread for it but it is interesting to me!

I used to flash a lot roms everyday on various devices. I didn't notice any side effects of it. As I know a little about hardware there is nothing to fear. You can imagine than one memory cell is one bit of data. If it withstands 100 000 writes it literally means that you can save data (eg. flash rom on it) 100 000 times. There is no way that you can cross this number even with everyday flashing. And it doesn't matter how much data we are writing because each memory cell deteriorates individually, so if we write on 1000 cells it means that every cell will deteriorate only by one write operation which means every cell will still be able to be written 99 999 times.
Another thing is that the storage memory in smartphones is usually one chip which means that all your data including /system partition (which you overwrite during rom flashing) and your photos and music on /data are on one physical device. The conclusion is that if you are afraid of rom flashing and wiping you should also be afraid of saving photos to internal memory. And since we are using our int. memory and change files placed on it a lot it means that we can flash roms as we please without consequences.

Thanks for the thorough explanation. I had my suspicions this would be the case and you've driven it home by explaining the whole music/data/pictures scenario. I used to flash PA and other roms on my N4 more often than I care to count but I never once saw a decrease in performance so it's good to know (personally and for others) the phone's read/write performance is not going to be realistically affected! :highfive:

I've flashed previous android devices ( HTC magic / Desire HD / SGS 3) 100+ times each with no obvious slow down, my albeit limited understanding was that NAND chips where rated for 100k+ P/E cycles?

Correct from the wiki link provided a few posts ago:
"Most commercially available flash products are guaranteed to withstand around 100,000 P/E cycles before the wear begins to deteriorate the integrity of the storage.[21] Micron Technology and Sun Microsystems announced an SLC NAND flash memory chip rated for 1,000,000 P/E cycles on 17 December 2008"
I am using Pocof1 March2019
lately,
1. it lags alot
2. heats up alot
3. freezes on touch and even applications doesn't work as swiftly as before!
now i have done the following
1. tried three different kernels after CLEAN flashing Roms such as Corvus, Crdroid, havoc , of Android 9 and 10 both and tested performance
2. device was running on Lawrun for last many months various updates on Pie rom
3. I FORMAT data and Reflashed MIUI11.0.8 by Fastboot method, clean flashing fully
4. I then format data again and changed by filesystem to f2fs
using now AEX / pie with sphinx3.1 and barely making thru day
device heats alot even on room temperature while ac working.
it is possible the cooling mechanism is deat? or thats the end of this device for me?
any sugggestions? before i go to market and start hunting for some other developer friendly device?
on same node, can one suggest me another Xiomi (LED panel only) which is very popular on xda , having many kernels and roms?
thank you in advance guys
Well if you've done all possible ts software wise, then it's likely an issue with hardware. If it's just heating issues depends on what you're doing. If you have a case, depending on thickness and what you are doing then it would cause heating problems and also if the phone overheats then performance dips.
In my case haven't had issues with the phone at all performance wise, battery, or anything else (only problem is signal, but that's an issue with my network, not the phone per se).
So based on my humble opinion, try having it checked for damages. Since it's out of warranty have a technician check it out, most technicians provide free diagnostics anyway, or if you're confident enough try opening the phone yourself, ifixit has a tutorial on it and unlike most phones it's an easy teardown. But if you're not confident look for a pro who offers free diagnostics first

You are using android 10 firmware with android 9, why ? If you use Android 10 with older firmwares than 11.0.4.0 it will cause issues and so is your case, just in reverse. Try to flash 11.0.8.0 from fastboot. Then flash recovery > AEX 7.3 + gapps. Or try Reloaded OS. It is a CAF rom so performance is great with good battery backup. You won't need any custom kernels. If no progress still then get ready to say goodbye to your poco.

You're confusing bro. As for data, why not just back it up? You yourself even stated that you've formatted, flashed and all that stuff right? So basically by now you have no internal data or you already have a backup. And as I said dude just have it inspected, they should be able to perform a checkup within the day if they aren't that busy. I've had issues before and in my country some where able to diagnose the issue.
FYI that's your problem if they can't diagnose it in a few hours, if you badly need the phone repaired then prep for it, "diskarte" as we call it, that means planning ahead in my country. Make plans and prep for it, either borrow an old phone from a friend for the mean time while you have yours in repair or something or ask maybe the repair guy has a spare dumb phone (some OEMS do that if you are in warranty anyway) or tell people not to call you on a certain day because you need to have the phone repaired.
Again, that's no longer my issue "diskartehan mo" make your own plans. I'm saying if you tried all software then it's hardware. If you don't want to go through all that hassle then just buy a new phone, simple as that

the reason why i am nervous here, locally there arent any good repair shops who can fix Xiaomi Devices. mostly go after iphones or samsungs hence i am pretty positive any repair shop person will open device, ask for something to be replaced and it wont matter
I'm on latest MIUI 11.0.8.0 with No Gravity Kernel, with NGK thermals. Performance is superb and runs very smooth. PUBG runs at constant 60FPS even on HDR + Extreme (used GFX tool).
CPU throttling test app provides results of 170K+ GIOPS. On stock MIUI kernel, this result doesn't cross 100k and even PUBG is not playable when there are many players nearby. Constant stuttering and lag.
You should try fastboot flashing the latest stable ROM and a custom kernel (NGK, ODK, Lawrun etc) to check, as stock MIUI kernel is laggy anyway. If everything is fine in hardware, this setup will provide you with Max performance.
My phone makes two years this november and it still gets 360k on antutu on same setup and never gets heated
*Changed the battery two months ago eve it didn't have any problem
