Strange issues by removing DRM services - running DK28

I am currently running ViperROM(DK28) version 3.0.3. I followed all of the instructions for fixing GPS on 2.2 and then flashed to this ROM.
Whenever I remove the DRM services I notice 2 strange things that happen:
1. Quadrant is not able to complete, it gets stuck on the first test at the Video Decoding.
2. I'm unable to select a new ringtone notification in handcent, when I press OK for my selection it hangs and I have to FC it.
The reason I want to remove the DRM services is that it appears to negatively affect battery life. I notice an improvement when they are removed. If I restore the DRM services everything starts working good again.
Any ideas?

I wont flame you,but this has been discussed plenty,search please...Anyway,you cant remove any of the 3 without losing some funcionaliy.So the only thing you can do is disable the one that runs at boot,not uninstall.I have tried this tip that orked for a day,once you have a fresh rom installed,play some music,watch a ripped movie,change a ringtone and notification,then remove all 3 services with sdx app removal or any other method you like.But like I said this will not work for more then 2 days at most

You're not the only one running into this issue.
I ended up rooting my Epic to get rid of all the sprint bloatware and what-not. Everything seemed to be going smooth from the stock standpoint. I removed Samsung Media hub first. Rebooted the phone and noticed nothing bad. Played around with the setup like that for a few days with no problems.
I next got rid of both the DRM service .apk's that were still running even after I got rid of the media hub... and then the problems started. For the first couple days I noticed DRAMATICALLY IMPROVED battery life and EXTRAORDINARY performance so I imagined what I did was a good thing: WRONG! A few days later, I noticed that if I assigned a sound to a notification or a ringtone *from the SD card*, that it would not work. I couldn't play sounds anymore and instead whenever I went to adjust the volume with said notes/tones selected, the Sound_service would crash.
However, I'm the only person I knew before now who has reported this issue so I'm sure there's not a lot of hubob to fix it. Every Epic is built different. Same parts or not. It's a mass-manufactured phone and each one will have its own quirks. There's my 2 cents.

I just froze the apps when I rooted with Titanium Backup but I thought I did something wrong and figured out that sound from apps seems to trigger the software crashes. No point if fixing it now. Flash DI18 and get the EC05 update and/or get EB13.

So can anyone confirm that the EC05 fixes the DRM issue? Otherwise there's no point in upgrading. I saw the release thread on here. Hecka people already having problems with the EC05. To upgrade for the Sprint ID packs? Won't see me do it...

Just let it do its thing. The amount of functonality you lose removing it is not worth the minute amount of battery life you'll save.

I have to disagree about the amount of battery life I'm saving being minute. When I had this damned DRM service running, I maybe got 10-12 hours with moderate usage. Without it running and now with SRF1.0.2 running (gets rid of IQ), plus SetCPU to (clocking 200-400 when screen off, undervolting 1.0-1.2 during usage) I'm getting a good 20 hours with heavy usage or I can go 2 days without charging if I only use texting.

I do actually remember getting a good bit more battery from deleting the DRM but at the end of the day I'd rather have my music files and apps work properly. I'm used to keeping a charger on me, its just the nature of owning a smart phone.

Yeah I'm with you on that one. Hopefully this will be one challenge [ACS] will be up to digging into.

I just tried stopping it in the running services menu and tested it on a few things with no issues. Doesn't take more than 15 seconds. I'll probably start incorporating it in to my TWS/Airplane mode routine (which just happens to need around 15 seconds supposedly) whenever I reboot.

That's what alot of other people have been saying too. I guess that's what I have to do.
Some threads on SDX about this say you can use some killers to stop it at bootup (personally I've always hated killers since Android 2.0, you don't need them anymore). As long as the .apk and .odex's are there. It's only when you uninstall or freeze it that you start to run into problems 1-3 days down the line.

I use Startup Auditor and it only kills it briefly. I've read all the arguments against Task Killer but I'm still a fan of it. Its especially useful to see what programs start up on their own and I do notice better performance after killing the ones that have no business being open. For everything else I just set it to ignore them.

Battery woes.... already?

I'm so confused.
Just got the mytouch 4g. Charged it, as it said in the book, until it was fully charged. Used it all day until it was drained and then recharged it this evening. Just looked at it now. In 5 hours since unplugging, it's down to 56%. 56!
So weird. And I barely use any apps. I made a conscious effort to keep it as clean as possible.
Help!

Hmmm alot of data is missing from your end but this is what I suggest as basic. Make your blacklight dim so it does not use alot of energy as this is the highest cause of battery drainage during actual awake time. Then disable any unwanted useless services from boot trust me there are lot and also disable them if they restarts. You can also use SetCPU taking you have OC based kernel then make profile to scale your mCPU based on max/avg/idle.
Best advice for you is don't charge the battery, get it low as 1% then do full charge and check your actual usage cycle the uptime/awake time later. Which rom are you using? OCing? if you don't need it just underclock it no need to OC just for the hell of it.

sounds like u need to turn off your network connection

when i leave my 4G/3G/Edge idle, it burns my batteries like mad
unless he has the screen on all day, i dont see how 5 hours would burn 50% of his batteries. even without killing all his task

No I was asking you to clarify as you mean to say completely disable data when you are idle? well you can do that if you have nothing that requires access but most folks have email and other elements that does require it. But yes it would improve it but that depends on him and how/what he has setup.
Whats your uptime/awake time with full bat cycle?

JuiceDefender does that, it disables the mobile data connection when the screen is off, but you can let some apps bypass that have it on every 15minutes or so to have it sync.
I've been playing around with it, and it does improve battery life, but it's not for me though, cause it does take a good 3-8 seconds until you get the "H" or your data connection back.

LOL I was curious and searched "Juice" my 8.1gb paid app archive of market that I just cURLed few days ago and came across UltimateJuice LOL so I guess ill run it. I have so many stuff... only if I could install it and test it but its not possible as its close to 11k apps.

Theres so much that can effect the batteries on these phones. Weak signal, apps running in the background, coutless things.
These are "super phones". I keepo a data cable in my pocket, and a car charger in the car at all times. My phone basically lives on the charger. Its easier that way. I know, not the answer you were looking for, but if you want your phone to do everything it was capable of then thats something you may have to deal with. You could turn all sync off and make sure nothing is ever doing anything in the background, but then whats the point in haing such an amazing phone?

C&P response from every other battery life thread:
werk said:
The first thing to check is if your phone is being affected by the init or suspend bugs. The good news is the former has an easy fix, and the latter can be temporarily fixed by a reboot.
First, download & install Watchdog Lite from the market. Then open its preferences and check "include phone processes," "monitor phone processes," and "display all phone processes." Then just use your phone as normal. It may take a while before you get an alert from Watchdog (and maybe you never will and it ends up you have a different problem). But if you do, note the process that is the culprit.
If it is the init process, go to settings>applications>development> check "usb debugging."
If it is the suspend process, reboot the phone. It should keep it from happening again for a while.
I know the second answer isn't really an answer, but so far it's all we've got for that problem. There is more information on the 2 problems in these threads:

I'm not rooted at all. Although I gladly rooted my previous phone (3g slide) I don't want to root this phone because I don't know of any ROMs that are EXACTLY like this Sense stock ROM on here, just without the crapware (games, VVM, so on). Is there one?

Ya you can go take a look in Ice Glacier v1.1.6 see which you like the regular or themed version.
QL: http://forum.xda-developers.com/showthread.php?t=844594

Battery life is all relative. Every single person will experience different battery life. The apps you have installed, the amount of time you spend on it and the time you spend on/in each app, distance from cell towers, distance from Wi-Fi sources, settings you have for every app and things like sync and what not.

I have the same problem at work (building)...poor reception = constantly reconnecting = major battery drain..

Thanks, I didn't think one existed. I just wish these cooks would put up some screenshots sometimes.
Quick unrelated question... is there any way I can JUST root for access to the phone and then delete the things I don't want with Titanium by myself. I really DO like the phone the way it is and I just wanna lose some of the network connected crap like the T-Mo faves, etc.
Thanks

Yes. You can just root and use the stock rom if you like. Use Titanium to freeze unwanted apps rather than uninstalling them. That way, if something starts behaving strangely, you can unfreeze apps to troubleshoot. Uninstalling system apps is permanent and Titanium doesn't backup system apks, only data. I haven't used it, but I believe Iced glacier is what you're looking for. The unthemed version is basically stock mt4g without bloat with some performance tweaks.

Thanks! You know, the thing is that with rooting, from my WinMo days when it was a really risky process, I developed this fear of rom flashing just because of the risk of screwing up. I know Android is much easier to flash with a ROM but it still freaks me out a bit and if it's not COMPLETELY necessary, as it was on the 3g slide I just had, I try not to do it. But I'll check out the unthemed Ice Glacier. I just wish I could see some screen shots or get an explained list of what mods are done to the stock rom on it.

The other thing you can do , if you like the stock ROM but just want to get rid of the bloatware, is to temp root using Visionary+, then use terminal, and disable the apps you don't want. I forgot where i saw it, but that's what I did and it works great. Also, if you ever want it back, it's not erased, just go back and enable it by typing "enable" instead of "disable" in the instructions below.
In Terminal Emulator (with root):
$"su" <enter>
#"pm list packages" <enter>
#"pm disable exact.NameOFApp.IncludingCase.SensitivityAnd.Periods" <enter>
#
You're done; it should be removed from your app drawer and everything. It will still show up in the package list, so if you want to enable it again, just pick it out of the list and follow the same directions replacing "disable" with "enable."

I don't get the concept of "temp rooting" vs real or full rooting. Does that mean it unroots if you reboot? What's the temp part?

That's it. Temp root goes away on reboot.

How I got my Battery Life Back!!

Through this forum and others, I was able to restore my battery life on the epic back to the 20 odd hours. I thought of writing my process here for the benefit of those who might be struggling with similar issues:
ROM: Clean GB
Tools: Better Battery Stats and Battery usage graph (BetterBatteryStats from the market. I think there is another one that is free. I will try and find it. However, the graph referred to is the one that is built it. When you see battery usage, click on the the top part and it shows the graph of battery drain. )
Observation: There is unusual usage of phone when the screen is off. The phone wakes up roughly once every 2-3 minutes even when the screen is off. Battery life between 3 and 5 hours. Emails do not sync or slow to sync.
1. Removing DRM files: The three said files were frozen using Titanium Backup. However, when I looked under battery usage/Android, I would still see DRM listed. So in the end, I UNINSTALLED all three files and the DRM was no longer listed. Not sure how much of a culprit it is but worth mentioning if you are freezing the files assuming they are not coming up. Check under Battery:
2. Calendar: This was the main culprit: Calendar storage was damaged on the phone and so, the phone was constantly polling to sync my calendar, in turn, running the battery down and making the phone slow. Cleared Calendar Storage using Titanium and that fixed the problem of syncing.
Emails:
1. Hotmail : Activesync (now on 1 hour polling)
2. Corporate: IMAP (1 hour)
(Above two running on Enhanced Email client). Not sure if standart client will also work, will test that and post later)
3. Gmail: using gmail app
Worth mentioning, that I used Enhanced Email and turned on logging to really see what was going on, hence coming to the issue of Calendar taking forever to sync.
3. SNS: The symptom was that SNS would be constanting restarting when seen under Applications/ Running services. Freezing the 2 sns files took care of that. Lost facebook status messages etc for contacts but made the phone faster.
4. KERNEL and CWM : Initially, although the phone was rooted, CWM was somehow, not FULLY installed. And for some reason, the phone would go to Sprint Recovery Menu. Also, worth mentioning, kernel usage was high. Installed the Clean_kernel and the latest CWM till I was satisfied the install was good and clean. A good way to test is to watch kernel usage on better battery stats and CWM behaviour when you go to Recovery.
5. Moved all content of SD card to PC and reformatted it. However, my SD card was fine, so did not see a change in performance, however, others might benefit, especially if you have movie files that the system is having a problem parsing.
I will add more if I think I missed something but doing the above took my phone from a paltry 3 hours on standby to more than 20 hours with usage. Totally acceptable and happy.
Hope this helps others.

Thanks, there's some interesting information in your post!

I cannot find either of those battery tools on the market... I also run clean GB...

I took into account what you mentioned, and removed SNS completely, hell I went a step further and just uninstalled the FB app. I will use the mobile site, and that is fine and dandy for me, I don't really need or want the constant notifications anyways.
I recommend the app Juice Defender, get the ultimate version, either pirate or paid, it is well worth it. Manages your 3g and wifi better, turns them off when the aren't needed, turns them on when they are. Really handy, has at least doubled my standby time.
I also recommend getting CPU Master, and having both it and voltage control on boot. CPU master lets you have profiles based on events, like the screen being off, or the battery getting to hot, again setup properly this also has done a number on my standby time.
Since I just flashed this kernel I haven't run a battery test yet, I am using Legendary 2.1 and IAP 2.0.6. Will run a test tonight to see how long the battery lasts for standby, hopefully it will turn on in the morning, it hasn't in the past very often.

The important part that I wanted to see was when the screen is off, is there any activity, meaning the phone is not truely speaking. At when the phone was at its worse, there was a activity roughly every 2 minutes. That was the main cause of the battery drain.

I cant say much about those tools cause I havent really used them. However, in my case, the problem was a bad calendar sync and SNS, I can see Juicedefender would maybe improve the battery life as it wont let the phone connect, but wont necessarily correct the issue at hand. Just my two cents.

FYI: I have the facebook app installed and it works fine. The problem is in the SNS when you put in your facebook info and it lets you sync fb events etc.
Also, by removing, I am hoping you mean you froze or deleted those two SNS files. Just watch Applications/Running to see if you see SNS there. If not, you are golden.

I also highly recommend this app, and have realized enormous power savings from it. My phone takes microscopic sips of electrons when in standby with JD.
However, I most emphatically DO NOT recommend that anyone be a thieving, pond-scum, crook with the ethics of a crack whore and obtain a pirated copy of this app, as saramon has recommended above. The author if this app has spent a lot of their time developing it, and should be compensated fairly. It is one of the best supported, most often update apps around. For the value it provides, there really isn't any legitimate argument justifying stealing it to avoid a few bucks.
Shame, saramon, shame.

I purchased JuiceDefender but ended up uninstalling it. Much easier just to toggle wifi and sync on-off manually, rather than tweaking it constantly. I found that the app causes more connection hassles and permission annoyances which offset any battery saving benefits it offers, and is yet another ram-draining backround process that slows my phone.

Never said that I did, but not everyone can afford it, just sayin'

I had 2 questions. First, what exactly is SNS? I see it restarting a lot as well, but I've been afraid it was something important so I've always left it alone.
And how would ClockworkMod affect battery life? Doesn't that only come into play when going into recovery mode?
Thanks

If you have SNS restarting it's probably because you removed the stock "Feeds & Updates" widget that came with your phone. Either freeze SNS in Titanium Backup (rooted), put the F&U widget back on one of your screens (unrooted) or kill it after every reboot (unrooted and no F&U widget).

He's not suggesting that you did. He is just saying that you shouldn't suggest it to others.
Piracy is for children that want to feel savvy because they know how to steal Photoshop. Thepiratebay.org, kat.ph, isohunt, and the various novas aren't original or cool, everyone knows about them. The difference is that some people have grown up and understand that people that do work deserve to be paid for it.
Besides it is what? $2-3? Anyone with the intention to buy a product could afford that.
I bought After Effects, Sony Vegas, and Photoshop Elements. Elements I got on sale for $50. The others were a couple versions old and I got them for $300 and $150 respectively. I am a poor college kid. However, I know I can get a part time job and pay for the things I need and that's what I did. I only needed to work for about a month to buy all my software and now I have a legal license to use it. So Sony and Adobe won't try to steal the rights to everything I make >.>
In short, stuff only seems expensive if you have no intentions of paying for it in the first place. My family lives well below the poverty line and I still can afford a pretty decent production set up. I'm sure anyone could conjure up $2. It's less than a round trip bus ride.
I know this was long enough, but I figure I should mention this isn't an attack on you or anyone else. I feel very strongly about the subject and I would say this regardless of who brings the subject up. I have a lot of friends that disagree with me and I have pirated software in the past, I just think that people deserve the money they worked for. Perhaps prices could even go down if everyone actually paid for their software.

I got some life back out of my battery with CM7. Then went back to ERA legendary. I did all the following:
Wiped / reformatted the sd card, odined and repartitioned, odined ec05, odined CWM5, flashed ei22, flashed the rom, then kernel I wanted to try, multiple setups.... no avail. (Monitoring every combo with battery status)
What I have done now is repackaged the rom, removed the "stock" launcher (swapped for zeam) and a couple apks I though were pointless to me, and replaced the kernel so there is all only one flash. I am really starting to think mix_n_match flashing was causing an issue for me. Also, CWM 5 odined and not using the app is not giving me all the aformentioned issues or running as a background process...
So far my battery life is much better with one flash, but one thing I notice in all cases is after a reboot, better battery stats shows "system" under process tab, always highest on the list. Once charged it goes away until a phone call, reboot, and even after forced sync.

my troll post for the day.

Battery life in SwiftDroid (may apply to other ROMs too).

Hai,
Since nobody bothered to answer my call to track down what drains the battery I decided to just post my findings and you do with it whatever you like...
In recent couple of months I've been experiencing quite nice battery life, almost a week on standby, which is basically on par with original LG ROM. The trick is simple:
It's happening as long as the Gallery app is NOT running.
I don't know what this piece of software does but when it's loaded to memory it stays in there and ignores attempts to terminate it, doesn't sleep when phone wants to and eats battery in a matter of single day. Unfortunately it seems some other apps use it directly or indirectly, like when Wi-Fi starts and/or by Market for example. Thus my solution is just to force close the Gallery after I finish activities which seem to require it.
I don't know whether root of the problem is with the app itself (like, CM modifications made so it's more cool, at the price) or it's just something else unearthed by certain SwiftDroid's configuration. To anyone who wishes to furher investigate my sincerest good luck. And I'd be grateful if results were published too.

You do with your phone what it damned pleases you. In case you haven't noticed the battery life is most often reported as either standby time or call time. In my typical usage battery lasts no less than two or three days but what 'typical usage' means may mean totally different things to me and to you.

Hm, even more shotgun approach to what I described. Having user data could be the primary reason for keeping the app installed. But thanks for tip anyway, may come handy one day.

There is gr8 app on xda, better batery state. With this app you can see what aplication keep wake lock, use cpu, gps, etc...

Hight CPU and battery usage on idle system; restarts don't help

I've got a problem with my S8 which is running latest, official, non-rooted XEO firmware. Specifically, it uses battery like crazy and heats up whilst doing nothing. This smells like a virus / malware infection or just... well, the last update was in December 2021 so it's also possible some system component is wonky OR... <shivers> some rootkit? I'm generally rather careful when installing apps, most of which will be coming in from official sources (Google Store) or at least fairly trusted sources.
Every so often I'll get a warning that a system component is using too much CPU and I should restart the phone - which obviously doesn't help at all. Also the battery drain is reported primarily by Android System and System Core (29 and 15% respectively). Battery usage stats generally don't add up because the listings don't add up to 100%. :/
I know the S8 is an old phone... and I know there are probably steps I should take prior to asking here - like a factory reset. But I'm really sceptical of doing a factory reset simply because I've got so much stuff on the phone that, while not impossible to backup, is certainly annoying (authenticator or banking apps for example - and I don't think the standard backup tools like those available from Google or Samsung backup such apps).
So I'd rather try some solutions or methods of dealing with the damned thing without resetting the phone first. Is there anything I can do?

You need to find the root cause. It may be a 3rd party using one or more of the Samsung system apps running under Android services, lol Legend for there are many... all lumped together.
A firewall with logging can help. Karma Firewall is what I use, uses almost no battery. Being rooted you have more options... use them.
Malware is always a possibility.
3rd party apps can cause hell. I don't allow any social media apps on the phone, ever.
Try in safe mode... if things calm down it's likely a 3rd party app. If so start going through the installed apps.
Clear system cache.

Sorry about the root thing, my bad.
If you're running on Android 9 or lower Karma Firewall's logging feature is fully active otherwise not. Samsung store>Galaxy Labs> Battery Tracker can be useful.
I use Accubattery's history page to get a quick idea of charge/discharge rates.
I use Device Care>storage>clean as well.
Make sure no cloud apps are running in the background.

Update: in safe mode the phone doesn't heat up and battery usage seems normal. So it's probably some app.
Alas, the firewall wasn't very helpful - it seemed that apps that attempted accessing the internet were your usual suspects - Play Store, One Drive or other sync apps, Vanced.
Any other suggestions on possibly nailing down the culprit?
PS. I've also decided to send Samsung an error report via the Members app - I don't know what their reply times are and I honestly don't expect much from them but who knows? Perhaps they'll come through.

Why other than maybe text messages is anything syncing? Take out the trash and go from there.
The ones that are connecting every minute or more when not open are prime suspects.
Some apps like Brave browser need to be closed out when not in use or they eat battery.
You can also try a hard reboot.

Update!
I left the phone in safe mode overnight. I mean, it seemed like things were better, so at least I'd have a stable phone.
Well, in the morning I was greeted with a severely depleted battery (went from 100 to 40 in the span of 6 hours) and I got the "high CPU usage" warning popup. The phone wasn't as hot to the touch tho.
So... Whatever is going on seems to happen also in safe mode, albeit less often? Or perhaps it's less "severe" where it doesn't heat up the phone but the drain is still there? But since safe mode is affected it's probably NOT an app, right?
At this point I'm completely baffled. Any other ideas?

Hard reset... hold power button until it powers off.
Try temporarily disabling Google play Services at night, see what that does.

OK, I'm baffled. I feel like I didn't really do anything but the phone is now running fine. Battery drain now might be better than ever!
Warms up on usage, obviously, but when idle it's nice and cool and battery drain seems minimal. I'll... leave it for a few days to see how this develops. It's very difficult to tell what the heck's the case here.

Retrace what you did. Reason being you may need to do it again. Really most times all you need to do is just "play" with it a bit (a lot). Almost impossible to crash a stock load, so explore and learn by playing with it. You are what you load and download; be careful with 3rd party apps they are the biggest potential hazards.
Once you have a fast, stable OS that's fulfilling its mission, let it be. Don't update or upgrade it.
Updates can and do break Sammy's. This N10+ is still running on Pie, current load is over 2yo. Rock solid stable and it runs like a bat out of hell with minimal maintenance. Security isn't an issue.

I have a suspicion this might have been some Samsung app (my bet's on Bixby) since those are likely still able to run in Safe Mode that got updated and then fixed...? Does that make sense?

I'm concerned about the last bit. I mean, upgrading to a new Android version is one thing but security updates are common, no?

Kill wittle bixby... you read it EULA?☠
It's more than one apk though. Takes a while to optimize a Sammy the first time
Well... if it's set up and used right Android 9 will run securely in the real world. No saving dumb bunnies anyway; they'll still get tagged even with the latest version
The proof is in my hand. Loaded over 2+ years ago and this N10+ UI version 1.5 is running clean like a bat out of hell. If I do get malware I can't erraticate in an hour or so, factory reset and change passwords.
My data is redundantly backed* up 4+ times, plus the onboard SD card used as a data drive. I'm ready to reload right now if I have to...
A malware forced reload is still less trouble than constantly updating and having the updates screw things up. That means more troubleshooting, finding new work arounds and still maybe needing a factory reset on top of all that. No.
Not vaxed either... not buying the hype.
*critical data must be redundantly backed up or sooner or latter it will likely be lost. Never encrypt data drives as you are the most likely to be locked out!

Oh I'd love that - but it's a system app and removing those without root is kind of... impossible? I can look into disabling it completely however - I never use it anyway. Since it's not a single app - any chance you got a link to the list of apps that need manual disabling?
Anyway, I'm still getting those damned warnings. The phone isn't constantly hot however, which is some improvement.

Package Disabler kills bixby proper.
You can also disable it with an adb edit. That's one of the first things I do.
Bixby is a hot mess best dump along the interstate... like Google Assistant it needs external servers for many of its functions. I may change my mind but it's eula is like eating dry hardtack for breakfast.
