    I think both of you MAY have valid points on rechargable battery cell tech' (of which i have zero)
    But surely we three would agree that $20 per 500discharges is far better than even THINKIN about whats best for your batt' am i wrong chaps? :thumbup:

    Guys, AT&T lets you upgrade after 18 months on contract. No chance I'm keeping this thing over 24 months. Battery life 5 years from now isn't an issue.
    I buy my phones mate.
    Unlocked phone with a prepay sim ends up cheaper, unltd data,txt etc but im on welfare so ill be buyin a couple of batterys before i can get a phone like this again

    Oh dude, I buy my phones outright too and I don't know where you are but in Australia, if you get a BYO (bring your own handset) month-to-month plan it works out WAY cheaper than prepaid. For 10 bucks a month I get $200 on voice/text credit, 2GB data, and $1000 voice/text to numbers on the same carrier. I basically never go over my credit limit regardless of how hardcore I use my phone. A lot of my friends think prepaid is the cheapest way to go but here you're not really getting your money's worth. Not sure if it's the same where you are though.

    Back to the original topic:

    Android system is a catch-all for a lot of processes, and it's not very helpful in figuring out what's going on. So far, I've only found one app that will show you at a detailed level what is using cpu, which is a pretty good proxy for battery use (other than screen and radio). That app is System Panel: https://play.google.com/store/apps/d...cGFuZWwucjEiXQ..

    The paid version (2.99) has a monitoring function that runs in the background and shows at a very detailed level what's going on over time. Some of what follows may work on the free version, but I'm not sure.

    Go into the app settings and check App CPU monitors, App CPU Time, and System processes. Then take a look at all the apps and processes that are using up cpu. Scroll all the way down to the bottom section of the app list, labeled "internal system processes," and you'll see the things that make up "Android System." Tapping any one of these rows will display a page with even more detailed information.

    Earlier this week, my SG3 suddenly went nuts on battery, losing about 40% of full charge just sitting, unused, over night. 20% is more typical for me. Using System Panel, I was able to track it down to the QOSMGR service, which was using more cpu than everything else combined. If you're having any kind of device performance issues, System Panel is worth it's weight in gold. Hmm, apps don't weigh anything, so I guess that old expression doesn't work here. But it's well worth the $3 asking price.

    Some Google searches turned up some links indicating QOSMGR had been a problem with some custom ROMs, and some recommendations to rename it with .bak on the end. I didn't really want to do that, because a properly working QOS manager should help with multi-tasking. I tried restarting the device, but that didn't seem to solve it. A full shutdown and reboot did, and I've not noticed a recurrence of the problem. Anyway, try using System Panel to see if you can figure out what part of Android System might be chewing up battery.

    Note, though, that many of these processes are always running in the background, and if you're not doing a lot with the phone Android System will, by default, become the major user of cpu and battery. The battery stats pictured above don't look out of line for Android System.

    Another trick I just learned this week: Go to Settings / Developer options, and make sure that's switched on. The scroll down and check "Show CPU usage." This will display an overlay, on top of whatever else is on your display, showing all the apps currently using cpu.(This is a lot easier to see on a dark background, so you might want to create a blank home screen with dark wallpaper.) If the same app or process is constantly at the top, that might be a problem. When I checked it, QOSMGR was at the top, and highlighted in red. Since I did the reboot, I haven't noticed that process show up in the list at all.

    Watching this overlay can provide some interesting info. I just noticed a facebook process show up, and I thought I had turned off all facebook background actions. Need to go double check that....

    He is having battery performance issues and since I've seen more than a few sources advising a full discharge to calibrate the battery, a practice that in my experience works in most cases, I relayed the information to him. While it may have some minor impact on the expected lifetime duration of his current battery, really what does he have to lose? His battery is under-performing severely right now so why not try a possible solution if he's facing having to purchase a new battery to replace a possibly defective one anyway.

    The OP came here for some advice, and I'm trying to offer possible solutions. If you're gonna try and explain why he shouldn't do it in his current situation then at the very least offer a counter-solution. Otherwise you're just implying that my advice is worthless and that he should do nothing and just put up with his average of 1.5 hours of screen time on a full charge, which isn't really helping anybody.
    Sorry you took it that way, I didn't mean that your advice was worthless, just that particular common misconception that the solution to battery problems is completely discharge your battery and then recharge it is counterproductive. That's all. Doesn't matter how long you keep your phone, it causes extra wear on your battery for no benefit.

    Okay, other ideas, most of which have been mentioned...I agree that looking at the battery usage information in settings is a good idea, if anything stands out there, that's a big help, low-hanging fruit. Also, one thing that I've found very helpful is the "BetterBattery Stats" app, where you can research what's causing your battery usage and what's keeping your phone awake using battery when it could be sleeping. Other things that I've found helpful are to set up the WiFi so that it only connects when either not sleeping or when it is plugged in and sleeping (I leave mobile data off unless I'm away from home, WiFi only at home). Since I let my phone charge all night (and leave mobile data off unless I'm away from home), this is a battery savings for me. I've also rooted my phone so that I can freeze the Verizon apps that want to run that I never use, along with the "email" app (I only use gmail). Right at the moment I have "maps" frozen since I"m not using it and it was running for inexplicable reasons, but will un-freeze it when I do need it next. I don't use Google Now, either. And I"m not syncing anything in the background, I sync manually when I go to look at gmail, etc. No widgets, just apps, and I let the weather app update only when I open it. There are lots of things that one can do, but it means really spending some time focusing on figuring out what's using your battery, and what you really want and what you can do without. And going through your settings to see what opportunities there are for power savings. A lot of little savings can add to a big savings, after you've hit the big battery eaters. In the end, though, your phone needs to be useful to you (and fun *smile*), so the things that you need and enjoy should be able to stay on.

    These were yesterday's stats. Horrific. I let it die and then recharge last night, so we'll see what happens today.
    Please note that the third photo is not my total screen time, but I wasn't sure if I would remember to screenshot it before it died, so I took that with 9 percent left.

    Just a quick thought, I see that you're using 4G/LTE. Personally, I use 3G, since I find 4G is a real battery sucker for me. You might try using 3G for a while and see if that makes a difference. Since I use WiFi at home, I only use 3G when I'm mobile, and 3G has been fine for me so far. When I did try 4G, I wasn't happy at all with it, but I must be hanging out in a lot of marginal 4G signal areas *smile*. Anyways, just a thought.

    Android system is on the top of my list. Why? It's really annoying and I don't know what app is sucking up my battery. Pics attached.

    See post #29, and here: http://forums.androidcentral.com/sam...ery-check.html

    It can often be very useful to read what other people have posted to see if it addresses your problem before asking your question. Even if QOSMGR isn't the problem, the approach I described will let you figure out what is running amok.
