So I rooted my phone got lagfix.. And mu phone has been very glitchy...getting stuck on screen.. Touch screen sometimes stops working... Sometimes I programs force close themselves... So I started removing bloatware vz crap tetris n4s.. I'm benchmarking 2155 but its like the phone ran better b4.. I've notice my ram is sometimes droping down to like 50 60 left.. So I task manager and end all apps.. And advances task killer end everything.. And my ran avl. Goes to like 136 and in five minutes its back down to 50 60.. What is going on?

Dont run task managers for one. And anytime you have > 40mb of ram, you should be fine. Try removing the lag fix and see where you are at after that. then try removing root. If this doesnt fix your issues take it back to VZW.
I'm not trying to argue.. But why shouldn't I use task killers? And my phone came with a task manager?

I had the same problem, not after rooting, but after doing the lag fix. I removed the lag fix this morning, and so far it's been all smooth sailing. The screen responds as it should, no lockups, no FCs.
Im a little sluggish too after root. No force closes but laggy when scrolling. Whether its changing screens or scrolling web pages. Not too bad just annoying since it was good before root. Lag fix didnt help so I deleted it, but I may try it again. So sure of the problem.

This may sound confusing and its so hard to explain, especially with just text but I'll try to explain the best I can.
Let's say android os is a chalk board and when you open an app the os writes on the board, some apps he writes more than others. The more Ram you ha e the bigger your chalk board. Now when the os gets to the end of the chalk board it simply erases what it wrote at the top and writes in its place and keeps going.
When you kill the tasks you are erasing the whole board that the os wrote on. So now the os has to rewrite what you erased ( killing battery and taking time) and im assuming after you kill apps you are opening another so its trying to write with two hands (multi tasking) and making it seem to run slower.

Also just plain rooting shouldn't do anything to make your phone run different, honestly it must be the "lag fix" that is messing things up. A good quadrant score doesn't mean a faster phone
Sent from my ADR6300 using XDA App
thanks wisenick.. that def makes sense... with your chalk board explination..lol.. and what exzactly is my quadrant score then? and what does lag fix do???
This is a good example of why quadrant scores mean very little in the real world... Im not entirely sure what the lagfix does, it obviously has to do with the on board memory and data. The memory scores in Quadrant skyrocket after the fix because whatever test it does is largely effected by the lagfix. But this doesn't mean that the phone will perform better, quite the opposite in my experience. The lag fix did nothing but make my phone lag and give me and huge quadrant score. Ill take stable real world usage and low quadrant score...
im with you on that on.. 4 sure... so do i just load up lagfix and click uninstall to get rid of it??? or is there some other way.. ive read of ppl doing it that way.. and not getting there memory back?
Removing the lag fix helped me a lot, but I still noticed the unlock screen would hang up a little. I just did a factory data reset, and wow! Everything seems to be working like a well oiled machine. And for those who are wondering, doing the data reset will not unroot your phone.

I called Verizon today regarding my battery life (at work which I started today I get sh*tty reception which kills my battery in 4 to 5 hours--usually last a full 12-14 hours pretty perfectly). The rep that I talked to quickly realized that I knew what I was talking about tech-wise and thankfully didn't treat me like an idiot.
She said something that got my attention though: she said HTC recently (as in the past few days) released something to Verizon reps saying that Task Killing apps actually interfere with the system and code in a way that drains battery *more* on the Thunderbolt than any other device thus far.
Anyone else heard of something like this or have a reason why it would do this?
*edit* I'm looking for like a dev answer to this... How it interferes with the system? I've seen the threads that explain how it messes with the Activity code but it seemed like it was more than that for the Thunderbolt.
Haven't gone a full day with ATK uninstalled but I'll try tomorrow and see how it goes.

they told me the same thing but not about the battery drain, just that it screws with the system
but on other phones (droid 1) they highly recommend using task killers.
obviously two different phones/companies, but still you'd think they say dont use them for all phones, not just certain phones, because most people feel they are useless.
But it hasn't screwed up anything that i've noticed, and my battery has actually improved since day one, so i think it depends on your phone. And i dont think my improvement is from task killers, i'm rooted and i think custom kernels and roms have helped increased battery life.
Id say whatever works for you do it, and dont worry about the task killers ruining you phone, but if you find out they are then dont use them.
good luck
I would guess that they'd negatively impact performance. The only reason you'd need a task killer is if you were on a 1.5-6 device. In all later version, tasks are managed natively as part of the core os.
One problem is with people using them to auto-kill apps far too aggressively. If you're constantly killing apps that are constantly re-launching (such as clock/weather/SMS/MMS/news/widgets/etc that tend to stay resident), you're going to end up up using a lot more processor time, and thus battery life, than if you just let the apps sit idle.
I heard that its because Android 2.2+ automatically restarts apps that you close and then it uses more memory to restart each time it is killed. There is a built in task killer in the phone anyways. No need for a secondary killer. But from my personal experience: yes I got worse battery life with task killer than without it. Although on my Droid x it was the opposite. Must depend on the phone

Your explanation is off a bit but you get a C+ for the spirit of it.
In short, Android use your free memory to cache programs into using spare resources. ATK then removes these apps from this free memory, making it free again. Android then uses your free memory to cache programs. Then ATK. Then Android. Etc... See the problem? Slows down your system and wastes battery doing it. You are correct in that there is a built-in memory-freeing system that does this really when it's needed. There are ways to influence how aggressively it frees memory up.
The reason it helped with your Droid X was because of how pathetic Blur was. With custom roms that removed most of Blur, ATK hurt a lot there as well.

+1 thank you... didn't feel like explaining all that
one thing to add for all you wondering...ram will use the same amount of power whether it is full or empty so don't' worry about using up all your ram...the android os will kill off apps and caches as needed to keep you running fast and efficient. our batteries life sucks because we use our phones so much or because (like me) we run beta software with bugs.
i've tested numerous times and sitting idle overnight (about 8 hours) on 4g OR WIFI, i will lose between 4 and 6 percent.
Quit muddying up the dev section! This has nothing to do with DEV!
This should probably be in the general section, and yes active task killers will ruin your battery life, if you have it uninstall it. The only way you should ever force close running apps is with the app management built into the android system and thats only for rogue apps that never stop running.

on droid x wit blur atk still hurt battery life. only worked on eclair.
One thing that I have encountered in supporting VZW technical issues, in addition to battery life, over-aggressive task killers, if not configured properly, can kill necessary apps. People call cause their alarm clock didn't go off, they didn't get text messages for 30 min to an hour, etc. Some of these programs *need* to run in the background.
Yeah from what I understand its not the phone but the os. On eclair task killers helped out . But froyo and gingerbread both take care of all of that in the back ground and using tk's affects the way the two os's are working. I was told all of this back on my Captivate and at the time I was hooked on task killers and Froyo leaks were just coming out. My batt life sucked and a dev some probably know , Designingears , explained all this to me and omg it was hard for me to take in and delete advanced task killer lol. But I did and have never looked back and it definitely improved my batt life. Now every now and then you just get a stubborn run away app that the os just can't stop, can't remember the app but theres a couple out there that take care of this and there not task killers. Me, I just reboot my phone every now and then and all is well .

so from what I've learned being in the business for 6+ years. The task killers kill everything where android needs certain things to run so your system doesn't lag. That being said a lot of the manufacturer are including a task killer in there new roms to over come this issue. Example the new droid x 2 has a new task killer app. Motorola was the first to say to Verizon no task killing apps and now HTC follows. Wont surprise me with the gingerbread updates to android phones if you see more companies build task killers into their roms. I stopped using a task killer last week and battery life has increased. Just my thoughts and opinion.

I second that. When I bought my Thunderbolt the clown at the store told me to put a task killer on it. I did that it killed the battery...On Perfect Strom 1.4 I am getting over 10 hours with out a task killer. Not scientific but I consider 10 hours good for battery life on this phone
Day 1 when I bought the TB a HTC rep was in the VZ store and he was saying same thing then about task killers worsening battery life and performance

exactly.. froyo and GB do the task management job well.. when I had my droid 1 running 2.0, i compared with and without a task killer, and battery life improved a little when I did use task killer. But then with froyo and above, it would actually make it worse to use one..
Me thinks that the phone processes is set up to where a simple task manger can kill them, thus messing with some essential processes. Which in turn, would make the phone have to use a little bit more juice to start the processes back up over and over.

Atk initially "sounds" good because most of us use to windows OS. Atk would/could be of use if droids ran windows... Droid is based off Linux and if you read up on how Linux operates, there is no need to constantly kill apps when it doesn't draw on system performance while in the background. Where the problem is, is that some apps have permissions to chill in the background and by killing them and the system brings them back up, just to be killed again. Not gonna drag thus on because I'm typing on my phone, but atk's aren't necessary.

Hi all;
For some reason, within the last couple of weeks, my phone has been freezing like crazy.
I uninstalled Advanced Task Killer and I use the installed Task Manager to monitor my ram usage and it's weird.
At any given time, I only have about 40-50 mb of ram left.
On average, out of 304 it shows that something is using anywhere from 230-260 mb of ram.
I shut everything down (using the task manager...shutting down level 1 and level 2) and still there is no change. I tried to not shut anything down to see if things would work themselves out, but still my ram is being eaten up.
I even went so far as to do a factory reset, hoping that this would fix the problem, but nada!
I've uninstalled every single program that I've installed within the last week or so, but still nothing.
My phone is becoming a brick and I don't know why. Next step is to call Tmobile, but seeing that my warranty is over, I"m sure that they will rape me with a replacement fee.
Any help would be most appreciated.
What rom? I'm experiencing the very same thing. Usually this happens when I've been in a rom for a very long time.

Don't need a task manager on Gingerbread and beyond. Just let everything be.
Don't even use a task manager, Android deals with apps in it's own ways, if you force kill them with a task killer, they'll be right back, ATK causes system instability.
Also, the 10+ apps are most likely bloatware and apps you installed that are scheduled to send/receive info intermittently, forcing the app to constantly open in the background for that purpose.
Sent from the resounding Rezound
These threads always make me angry because the people who post "ATK IS WORTHLESS" are just as ignorant as those who think ATK is a requirement.
99/100, ATK won't be necessary these days. Android has built in task management. ATK is really something that store reps were trained on because task management in Eclair was pretty horrible.
Think about it like this. Those 10+ apps are being shut down, then using extra CPU cycles to start up every time you kill them! That's going to kill battery faster than letting them live.
Since Froyo and beyond (meaning Gingerbread, Honeycomb, and Ice Cream Sandwich), ATK is essentially unnecessary. You can uninstall it and won't notice much of a difference most of the time. They've done studies and found on some devices, ATK will either improve battery or hurt battery by +/- 5 minutes (in other words, no battery improvement except possibly a negligible 5 minutes on average for a couple of devices). Search for the article on Droid Life if you're interested.
With that being said, ATK can still be useful. Did Angry Birds crash freeze on you and is causing your system to run slowly? ATK kill it. Is Facebook completely stuck because it's trying to find your location and you have 0 GPS signal? ATK kill it. Is Currents sucking up your battery because it's trying to download on a weak data signal? ATK kill it.
I haven't had ATK installed in a while, but what I do have is Watch Dog. Watch Dog allows you to set a CPU threshold. When certain apps start sucking on your CPU for extended amounts of time, it pops up an alert. From there, you can Ignore it, White List it, or Kill it. This way you're not just killing tasks for the sake of killing tasks.

Leave your freaking memory management to the OS. You are not smarter than your phone, you're murdering your battery life AND performance.
If you kill all apps, your phone's going to sit there for the next 90 seconds re-launching half the stuff you just closed, pegged at 100% CPU.
Even so, if you're sitting there on LTE, 1% per hour is perfectly normal.
The other thing with cell standby being as high as it is, you might be getting signal loss or excessive network switching.
Signal loss is the bane of battery life on any device.

I let my phone run down to 10% for the first time since I bought it 3 weeks ago, it was at 2 days 14 hours when I put it on the charger. It took 4.5 hours to get back to 100%. Now I know I can charge every other day instead of daily which should be better for my battery.
I agree with Travis that a reboot should be done every day, and never use a task killer, Let the phone manage your memory and quit worrying about it,
I never use a task killer. However I never reboot. I dont see a need seeing how stable it is. Unix based. Like... my other phones have had 60 days and still stable and fine. My tablets over 100 still going fine.. reboot shouldnt ever be necessary.

No, not UNIX based.
GNU/Linux based running a virtual machine for your applications, which are Java. It is stable, but not (and never will be) as stable as UNIX or even pure GNU/Linux. Java VMs in themselves aren't exactly the most stable things and despite GC can slow down at times and have other quirks. In a perfect world where every Android app dev is super dev and codes perfectly, then a reboot would never be needed.
That said, you have mentioned several times ending all tasks on your phone...you are using the built-in task manager from Samsung which is still a bad idea.

About 10 times a day, but that is because I am using the phone when building android apps and end up hot rebooting myself half the time when I screw something up
Is bragging about up time, a stat that no one cares about, (for good reason) more important then battery life and stability?
I could leave my car running for a pretty long time and brag about that. Take it to the gas station and pump the gas while still running and all. But that's a really bad idea.
The only benefit is an imaginary number that is only important to you, while sacrificing real word performance.
I restart my phone probably once or twice a day on average. Sometimes I don't restart it all, others I do maybe 3 or 4 times.
I definitely recommend a reboot everyday. Not only for android devices, computers also.
Sent from my SCH-I605 using xda premium
Why are people so adamant about a reboot every day? Seriously, that was sort of necessary like 10 years ago, but modern devices really don't require it. They have enough disk/processing/memory capacity to be able to dynamically allocate resources without getting all messed up. It was a big deal when RAM was expensive and page files/swap spaces were heavily used because magnetic hard disk access is slow, especially when you have to read/write/modify a page file all the time. That's not an issue many modern PCs (I've had my page file turned off for a few years now.. well, mostly off, it's set to 16MB because some programs don't work with it off) and certainly not an issue on phones without dedicated swap space..
Maybe I'm missing something, but I just don't see it. Especially if you're on a high-end device. I reboot my phone/computer when something requires it, such as windows updates, driver updates, needing to flash something in recovery, etc. The "once a day" mark is really arbitrary, especially in a usage-independent context. Just reboot it when it needs it.

Absolutely this. Rebooting arbitrarily is 100% unnecessary.
