[Q] Galaxy S4 battery drain

Hi,
I have an i9505 which is currently running NF1/1854187. CSC is btu and this was a recent clean install (and I've done the same preiviously)
I did run rooted for about a year. titanium backup to shut off a lot of bloatware with fine grained control, the xposed framework to tweak, and of course root access to use tools like better battery stats, and on occasion a custom kernel. The end result was good stability and power usage. Very happy.
However more apps are blocking root, and some manage to even detect root when using various root blockers, temporary unrooting or EVEN permanent unrooting (supersu). In particular the worst is "skygo" which I like to use to catch some content like f1 when out and about. My corporate software also detects root and wipes all enterprise data the instant it's detected.. plus add in a banking app and comms app, and keeping root was getting tricky.
On to my issue. Quite frequently the phone batter drops far too quicly. Today's example?
- In one hour battery drop is 10% (100->90)
- "Android OS is taking 30 mins of CPU, and 30 mins keep awake
- GSAM confirms 90%+ of the power usage is kernel/android os
- pretty much every user-disable-able app is disabled
- android OS contains loads of processes, making it tricky to track cause
- full wakelock data is not avaulable when not rooted
- user wakelocks total is down in terms of a few minutes only
This doesn't always happen.. sometimes the phone will be well behaved. the drop was around 3%/hour, and then I tried battery guru to limit auto-sync, and it did seem to help when well behaved, dropping usage to say 1.8% , but the core issue occurs with/without
I'm aware of many of the hints/tips of saving power, though I've done many of these.
I've previously seen mediaserver go awol and spin cpu, and deleted my spotify cache. Since then that process has seemed ok
Very frustrating that these silly "can't be root" situations (after all I'm "root" on all my linux boxes and admin on my windows boxes!) actually result in a LESS USABLE handset.
Is anyone else currently going through a similar situation?
I've just again checked settings and disabled airview/sensor related stuff. Next step if that doesn't help is to remove all my corporate sw stack and see how thing go - a frustrating process of elimination. As above I've already gone through a full reset with no help

try rerooting the phone then install SuperSU and choose FULL UNROOT. if you need to have a phone that will work with Sky Go etc. I've done this hundreds of times on the phone and it works guaranteed to get SkyGo working, so long as you have STOCK KERNEL. I am yet to find a custom kernel that does NOT autoroot, or mess up SkyGo in some other way. So be sure to be on stock kernel then FULL UNROOT.
As for the battery drain, have you updated to the latest version of SkyGo? Most of the old versions had some SEVERE wakelock issues where the app would be constantly running in the background and draining battery like mad. If you update to the latest version I've had very good results with it. Failing that you can drag the apps icon to the top of the screen where it says "app info" and from there you can "force stop" the app. I bet that this is the app which is killing your battery at present.

Many thanks for that very clear, specific information. I had applied a custom kernel, and unrooted that - a classic error, changing two things at once. That did not work, with sky complaining about root - though the other apps were ok (sky are smart....)
With that information it gives me much more confidence I can indeed root/unroot the stock kernel, so I'm going to try that - at least it will let me tweak what packages are enabled - ie disable some of the samsung stuff I don't want/need that isn't user-disable-able. Any other thoughts welcome

Oh yes I'm bang up to date - my issue seemed more with one of the ootb packages rather than skygo. I have had the sky go issue in the past, but only when it's previously been run. I'm very used to wakelocks, and the user app wakelocks were well under control. That being said it's still annoying you can't get the app level breakdown unless rooted.
Anyway thanks again, that info about sky go/stock kernel/rooting was so helpful
Nigel.

Just to confirm root, unroot worked fine...
I disabled more apps with titanium backup. I didn't quite get as far as installing the xposed framework again, this stint was purely to prune down the apps somewhat. If that works/is stable I can tweak further
A little shame it requires hooking up to the pc to root again, but it's better than nothing!
SkyGo is still working, and corporate email threw a wobbly (by design) but is working again after the reroot

you don't need a pc to reroot though......store the towelroot apk on your phones mem card and just reinstall it from the phone (go to file managed, mem card, select the apk and install). then download supersu from play store, update, reboot, update.reboot. done. that's the good thing about using this method to root/unroot, you can do it all from the phone directly, no need to use a pc at all
::EDIT::
1 - root with towelroot
2 - install SuperSU from PlayStore and attempt to open and update binary (it may fail)
3 - reboot and open SuperSU again, if it again asks to update binary it will work this time, reboot once more).
4 - set up your options in SuperSU (e.g. no notification, trust system user etc).
5 - do whatever you need to do with root
6 - to UNROOT just choose "Full Unroot" option within SuperSU app, THEN also uninstall towelroot.
7 - Reboot and you'll be UN rooted and apps like SkyGo etc will work perfectly.
8 - If you need to re-root, repeat the process from step 1.

Thanks again. I'd been using cf auto root for a few years. Hadn't tried towel root. Thanks for the tips. Very helpful

[Q] i need help, bricked my SM-g870a

Disclaimer: this has nothing to do with the quality of the program i was working with and everything to do with MY lack of knowledge of android systems and what I am doing.
purchesed: 8/23.2014
my att gs870a
rooted: towelroot
xposed module: donkeyguard
the last few things that i had done was to install ABP for android and then downloaded donkeyguard. i checked the box in modules for Xposed installer and it required a reboot. i rebooted device and it starts booting up and gets to att screen and stops.
boot loader is set to freeze most of the automatic updates including KNOX
i have root cloaker in place
Xposed privacy guard in place
i can reboot into manual holding up arrow, home and power keys
from there i dont know what to select: restore factory defaults?
please help
i can try to provide any extra information that you may require and i have more rooted updates on device. please take pity on a NOOB. i dont claim anything other than sometimes a little knowledge is dangerous.
thanks
patrrick
sorry that this is my first post. i have learned alot form this forum. this is my first android device. i had been on using BB 9930 up to now.

hi again
here is what i was able to work thru. hard boot holding vol/home/power into manual. at this point i was able to get kies3 to read device. reset to factory options and reinstalled last backup. phone is back up and running/rooted and reloaded with the exception of a couple of the last programs i had installed. now for the question:
it seems to be running slower than it was before. used TB to refreeze a number of apps and i was hoping it would show me if there were dup's. i am thinking this could be causing the slower operation. have used Antutu to check it against prior to brick. any thoughts on what might be causing it?
thanks in advance

ok, back
vndn thanks for the suggestion. what i did was take a close look at all the settings after the reinstall and what i found was Wifi had been switched to manual in advanced settings and was causing conflict with the system operation causing the slower operation. seems to be fine now. thanks for the help.

Phone Lags after root and Greenify Problem

I just rooted my N910C and i noticed it lags? i try to install Greenify and also it lags sometimes it wont even ask for SuperSU access and i tried turning off the power saving and even if its off the icon on status bar is still there. another thing is that when i install greenify i can't un install it normally i tried on google store and the only option is Deactivate. i tried uninstalling it via "Drag icon and drag to the trash can icon" and it says that i need to disable the administrator access and i tried unchecking it but it lags. so what i did was uninstall it via titanium back up and it worked. but still my phone lags any suggestion?
another problem is that my computer does not detect my phone anymore? but when i plug it in it charges and the "windows notification sound" knowing that it detects a device being plugged but i cant see it on my computer so i cant access the Internal storage
update*
so i tried inserting my phone to another PC to make sure and the drivers installs but when installing the MTP device it fails
please i need help i know the root process triggered knox so warranty is already voided

Mine too.. I rooted my stock rom, noticed lag on almost everything, typing, browsing, opening apps, settings... no idea why...then i installed custom rom..!

i tried paring a bluetooth from my Nvidia Shield and it even lags.. the notification with the Pin code is Soooooo delay so i cant pair properly example on my shield i tried to pair the Note 4 shield will show a pairing confirmation with pin code and on the tablet it wont until around 1minute
edit..
is it safe to just unroot the phone using SuperSU Full unroot method?

in that case, download the correct firmware from sammobile.com, i.e. according to your region / carrier.

Thanks everything is back to normal and lag was gone. but root was also gone im afraid to root again the lag might come back =(

I don't know if your Note 4 version is the same with mine (Mine is N910H), mine is rooted + greenify but I experience a little to no lag.
Bluetooth pairing in an instant.
Apps open in an instant.
Buttons response in also quick.
Perhaps background process or some rogue apps do the lag?

Yes iv'e tried slimming down to know the problem so what i did was
1) flash stock firmware (status ok)
2) root my device (status ok)
3) install greenify, six axis & some adblocker (status ok)
4) install xposed (status ok)
5) install xposed binaries and update (status phone lags)
6) uninstall xpoesed binaries amd updates (status ok)

Just do a search here; S-health app and Private mode interferes with xposed (or is it the other way around?) There are some settings you can change (disable secure storage in build.prop) that will get rid of the lag caused by xposed.

I concur that it is the exposed framework that is the culprit. It doesn't work well on samsung kitkat phones but only CM and AOSP. It will even ruin your private mode! So as for convinience I don't install it on Sammy phones

I think I have maleware and a factory reset did nothing

So I think I may have gotten maleware from trying to update my pornhub app. Yea yea I know I know but its that time of the month for my wife and well the rest isnt needed lol. Honestly im not even sure if thats what caused it as ive had the app for about a year now and never had a problem. I did download some new keyboard & themes before all this started so those might be the culprit though I doubt it. Now all of a sudden the phone is installing so many random apps, multiple lock screens, is resetting itself, freezing, and acting all types of weird. Its not just porn related stuff its installing either im getting stuff for clash of clans, travelocity, money something, solitaire, etc. I was able to get it hooked up to my computer to try and manually remove stuff but im not finding certain apps like the travelocity & solitaire and going through phones app manager doesnt allow me to uninstall them even though they are present. I am also seeing little android icons next to some things which are named pornclub which is what makes me think it was the pornhub app.
Please for the love of everything help me get my phone back to working normally. Would flashing the phone work since a factory reset did nothing? I did put the phone in safe mode and was able to clear the cache of some of the apps which seemed to have taken them out but it did nothing for others even though there were no uninstall options.

Did you reset using stock recovery? Sometimes, stock recovery is needed to wipe data, cache.

Use the odin tool to reflash every thing. If it is a virus I'm 99% sure that'll get it.

Flashing with Odin will not always wipe the data partition; therefore, it is a good idea to perform a factory reset before booting the newly-installed rom for the first time.

Usually, partitioning is required if Odin can't pull the partition table from the phone.
Which bootloader is on the i337? Is the phone the att version of the s4?

Did you delete the folders on your phone's internal storage before you did a factory reset? Sometimes it doesn't delete everything.
I'd start by plugging the phone back into the computer, delete all the folders and files on the internal storage and do the factory reset again. See if that helps. I'd also make sure to not have the phone restore apps when you do the initial startup.

Hi! I have too such problem. Only I don't know that my children set. The only way to get rid of a virus it to reinstall completely the Android. You need to pass in a subject about your phone and to esteem as to reinstall the Android.

After using UPSM Manager and UPSM+ almost all apps disabled/disappeared

Hi there
I wanted to add Messenger to UPSM screen (Ultra power saving mode), so I've tried UPSM Manager and UPSM+. None of them worked on my Galaxy S5 however, after few tries almost all of my apps disappeared. There are a few left. System: Contacts, Text messages, Phone, Settings plus Google and Lockwatch. That's all. The rest disappeared.
On application manager in settings I can see all of them, most of them have status "disabled".
I've downloaded those two apps from here:
UPSM Manager - https://forum.xda-developers.com/showthread.php?t=2751785
UPSM+ - http://downloadapk.net/down_UPSM-ROOT.html
I've read that there is a very high probability that they won't work and that Google does not refund price in such case hence downloading .apk - could it be some kind of trojan from the 2nd link?
I've connected with adb console and
PHP:
pm list packages -d
shows 300+ packages as disabled.
PHP:
pm list packages -d | while read line ; do pm enable ${line#*:} ; done
fails with
PHP:
Error: java.lang.SecurityException: Permission Denial: attempt to change component state from ...
I can't run su as it freezes adb shell - su is also disabled so I can't enable it nor reinstall (Failure [INSTALL_FAILED_INTERNAL_ERROR])
Any hint how to restore my phone? Right now it has less features than Nokia 3210...

So maybe I'll ask a different question. Is there a way in my current state to regain root access (via adb shell) and enable disabled apps?

Hi,
In order to get helped it is always useful to provide at the beginning some basic info like phone model, firmware ver , root, recovery (custom or stock) etc.
Easiest way when you messed up your phone would be just restore your nandroid backup but I assume that you didn't make one, did you?
If not, easiest way IMO to regain root is just flashing CF-autoroot or if you have a custom recovery supersu zip file.

I wrote in Galaxy S5 forum so
Anyway: Samsung Galaxy S5 (SM-G900F), Android 5.0, G900FXXU1BOJ1, stock os, rooted
Haven't heard of nandroid before. I had titanium backup, but that's just apps I assume and they are still present on the phone, just disabled.
I haven't heard of CF-autoroot neither, but after picking matching details I got to desktop.firmware.mobi/device:370/firmware:12219 (I can't post urls with <10 posts). I'll have to read what to do with it without breaking a phone even more.

Here is the link to CF-autoroot for S5 variants:
https://forum.xda-developers.com/showthread.php?t=2696537
For applying you need to be familiar with using odin pc software. Be aware that this will trigger KNOX flag if yours is still 0x0.
By the way, how did you root your device initially?

KNOX was set when I initially enable root. To be honest, I can't recall which software I used, but it just worked without any problems. I was more than a year ago. Maybe it was CF but I just don't remember the name?
Anyway, I've generated image via CF-autoroot but it fails:
<ID:0/004> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
and now phone says "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again" :-/

Hmm, so you still can't enable any disabled apps? I am afraid that you may need to try factory reset and if this doesn't help then re-flash complete firmware with full wipe. Before I would make backup of all useful staff what is still working and available in your phone.
Edit: did you read whole app thread? There are a few solutions/workarounds which helped some users with their issues but not sure if it is applicable to your problem,

There is a button "delete everything" but it does not work. Nothing happens when I click it. So the next step is to reflash firmware? That seems like a bit over my knowledge at the moment :/
Also, I assume there is no way to backup sms/mms - not able to install any backup soft and no root for adb:
PHP:
adb pull /data/data/com.android.providers.telephony/databases/mmssms.db
adb: error: failed to copy '/data/data/com.android.providers.telephony/databases/mmssms.db' to '.\mmssms.db': remote Permission denied
I'll try from recovery menu.

Ok, so it worked from recovery menu. Data are wiped, phone install some german bloatware and it's like when I first bought it. As I suspected, despite Google backup enabled, it does not work. No apps are being installed. I have to recreate every single app with it's data. That's a small disaster, ech..
Samsung backup restored some sms/mms but from February this year (heh).
Looks like all those automatic backup from Samsung and Google does not work at all and I should probably do some cyclic manual data dump. So why all those backup settings if it does nothing at all?
Anyway, thanks for your help.

Sorry for that. What do you mean by saying "no apps installed" You wrote before that your apps (user and most of the system) have been disabled, not uninstalled by the UPSM.
Are all your disabled system apps still at the same state after factory reset?
You wrote german bloatware? It looks like you have German branded Lollipop 5.0 firmware installed. I would definitely move to Polish latest unbranded (XEO) Marsmallow 6.0.1 to clean up your phone or if you wish to have rooted and debloated stock-based firmware then this rom is a very good alternative:

By saying "no apps installed" I meant that after factory reset (wipe from recovery menu) and signing into my google account, backup restore did not install anything. But I've done yet another reset, this time from options and this time I've set up google account on welcome wizard and.. it worked, google backup restored all 107 apps BUT with no settings (they claim that settings should be also restored), so I have all my apps, but with no settings, so like after fresh install. I'm recreating everything from scratch, one by one.

Yup, phone was bought as (I'm not sure how to translate "powystawowy") refurbished, from shop exhibition(?), a bit cracked on corners, but 2x cheaper. Anyway, it was just a matter of uninstalling 5 German apps (with root of course).
I did not put any other firmware as the one from Samsung has some unique features like mentioned ultra power saving which I enjoy on long travels. I've read that custom roms does not support this or NFC and few others.
