So, i bought an AT&T galaxy s6 and im using it on Cricket. I have really good service here in Delaware. Data and call quality are always great! However, my battery dies very quickly, usually only laster about 7 hours woth regular use. Sometimes, it drops about 12% an hour with no use at all. On airplane mode, it will go hours without dropping at all. Any ideas what is causing this?

How's the battery life with RIL enabled? Significant improvement, or still pretty crappy?
I heard someone awhile ago say they couldn't get through Avatar on a full charge. Is this still the case, even with tweaks?
I'm considering picking up the S7 as my main unit (ditching my OG Droid at last), and I need to know if it's even feasible. I would love to do this, but if I can't get through a day I can't do it. Here are things I'm thinking of doing:
-DJ_Steve's ROM with RIL enabled
-Juice Defender to set my 2G/3G/4G settings; 4G for internet/calls, 3G/2G for notifications/idle/gaming/etc. (depending on which is lower battery consumption).
What kind of battery life can I expect? I still have to get out of my VZW contract (ought to be this month), so I'm still researching what the best solution will be for me. I really want a 4G, dual core, 7" tablet. I've used the Streak 7 at the T-Mo store and I love it (screen is great, unit was very snappy; 4G seemed a bit slow, but it was during peak hours).
So, anyone test their battery life and see any improvements over stock?
Haven't tried any wifi calling on my ds7. Using stock 2.2.2 and I can get about 3-4 hours of playback using rockplayer before battery dies. Doubt you'd make it through the day. It seems to drain some battery even on standby.

Well, I couldn't get out of my Verizon contract and I didn't really get an answer to my question, so I really had only one choice.
I got a Streak 7 this last weekend. Logic be damned!
Loving this thing, so far. I got it rooted/Rom'd (thanks to all that worked on that!). Battery conservation while maintaining data connectivity is a big issue for me, so I'll be tweaking a few things and seeing how it goes. I'll report whatever I find out.
So, ril-off will disable all mobile data (thanks, Hellzya!). That's not an option, as this is now my main device. For anyone else in my boat, here are a couple of things that might work:
This app is basically a shortcut to your network system settings. Seems to work fine; I'm using it to toggle to 2G when I'm not using the device (but still want to get notifications), and then 3G/4G when I am. The S7 switches between HSPA and GSM a lot when I'm at my house due to me being on the fringe of a 4G tower; I'll see if this fixes that issue and report back.
This thread has another app that will automatically switch to 2G when the screen is off. I have yet to try it, but I'll update once I do.
Long live the battery!
Update: From what I'm reading, the HSPA antenna uses less juice than the EDGE one, so I've been setting it to HSPA only. Underclocked as much as possible when the screen is off (216, I believe), and overclocked to 1200 (lower Quadrant, of course, but I don't notice a performance degradation).
I had it off the charger all day, yesterday, and then tethered my Cr48 to it for quite some time. I was off the charger at ~7AM, started tethering at ~9PM. I had maybe 20-30% battery at that time. I hadn't used it much that day; just some light internet usage, ~15 minutes of streaming Pandora (high quality setting), one VOIP call, and a few, benchmark tests. After about 30-60 minutes of tethering, the battery was in the red so I hooked it up to the charger and continued to tether.
So far, so good. The battery is livable, but by no means great. This wasn't a really big usage day, though, but at least the idle isn't eating up too much juice. I'll have to see what kind of heavy usage I can get out of it (tethering, video streaming, etc.).
Hoping, of course, that HC gives us back some precious battery life.
Symptoms started off with 4G being horribly slow (1-3mb where I normally get 20-25). Wireless hotspot (paid for) was pulling even less and not loading pages. I tried a factory reset to no avail. To compound the issues, the LTE chip on the phone completely died. It would not pull anything 4G and 3G would shut down after a few minutes. 4G would no longer turn on - and this was before the so called 4G outage.
Verizon tech support was so abysmal, it made me wonder how they got their positions. With two phones side by side - thunderbolt pulling 25mbs, and the Bionic pulling 1-2mbs .2 upload, it was perfectly fine to them. "We dont guarantee speeds". Ok fine I understand that, but dont tell me something isnt wrong with the phone when there clearly is. When a 4G LTE connection with 5 bars is pulling speeds consistent with 3G... um ya.
The battery was also draining like no ones business with everything turned off (syncing, GPS, etc). Im talking 15% battery drain every 45 minutes with hardly any usage.
Compounding the issues - hotspot would fail after about 10 minutes and completely shut down my data. They also claimed there was nothing wrong with my phone in this instance so I figured it was best to bring it to a Verizon store.
New phone - 25mb down 8 up (speeds ive never seen on my bionic) hotspot working perfectly as is everything else. The guy at the Verizon store laughed about the phone support and just had one of their techs look at it.
So if you have any issues I highly recommend finding a VW with a service center because its a crap shoot anytime you call their support line.
Happy camper once again
I've got a Galaxy s4 active on vodafone (UK) running 4.4.2, kernel version 3.4.0-2450186. The battery has been getting bad ever since kitcat went on it, but its now got ridiculous. Having looked at battery usage, a massive amount is being taken up by the system. Clicking on the graph very dramatically shows why - unless I turn on aeroplane mode, the Wifi is sitting there quite happily on, but not telling me. And I have no idea how to fix this. A few internet searches have suggested that there is a programme on there that keeps the wifi on to find a wifi signal to latch on to, but I cannot find that programme for the life of me. Anyone got any suggestions? This is completely ruining my phone - the battery isn't lasting half a day on standby at the minute.
Thanks.
I have had extremely terrible battery life with this phone since the day I got it in April. Probably the worst ive had with any phone ever and ive had dozens. My cell standby is at 147% in the battery statistics. Absolutely nuts! I had a manufacturer replacement so it's not my actual phone. I live in a fringe area that dissipates between 0-3 bars as well as switching between 3G and 4G which is obviously no good for the battery. I recently figured out that you can just turn off cell signal with airplane mode and then turn wifi and wifi calling back on so that there is no cell standby. I thought it would help but my battery is no better. Can someone please help give me some insight into what gives? I just don't get it. Such a great phone ruined by such a terrible terrible battery. BTW I have all my downloaded apps optimized, limited sync only for gmail,location off, screen brightness very low and I have package disabler pro installed with the known tmobile battery hogging apps disabled.
Do you have Google now enabled? Disable it if so, also go into wifi advanced settings and disable wifi always scanning if it's enabled

I have all advanced wifi options disabled , no Google now. Just checked battery usage. Somehow with airplane mode on and only wifi and wifi calling I have even more increased cell standby. It says 179%. How could that be. Even if I was struggling for signal that hardcore and I wasn't on airplane mode I have never seen anybody ever report there's to be THAT high.

There is something seriously wrong with your device. That's not normal drain, it's not even possible. I would either talk to T-Mobile or Samsung about a warranty exchange

Right, I understood without airplane mode on because my phone is literally constantly switching between LTE and Edge but how the hell would that be happening with the radio off lol. I could be being misled by the battery stats by not giving it enough time after trying airplane mode. Could be the left over stats from before. I only tested it for a couple hours. Visually to the eye it didn't seem like the battery life was much better though. I wonder if wifi calling is an issue or cause? I can't do a warranty replacement. I already used one because my first S6 had some random line of of bright light suddenly go through it that wouldn't go away. I really dislike this phone lol. Wish they'd just let me replace it for something else entirely. I miss CM. Now it's at 242% but it says time on 2 days 11 hours 46 minutes , time without signal 38%, total connection time 1 day 19 hours and six minutes, so maybe the high percentage is just because of how long the phone has been on with out a cycle. I only tried airplane mode for a little while one day and ever since I left it off. Why idk.

You should be able to get a replacement anyway, don't know if having insurance matters but at least for me, I've swapped previous devices multiple times for a replacement. Try doing a factory reset and charge the device to 100%. Only install the minimum apps to get you through and try that for a full day, see how that works out. Also make sure you are on latest firmware which at the moment is DOJ7

Yes I am on DOJ7. I was stock for the longest time then I decided to root and try some roms. Didn't like much of any and I wanted the DOJ7 update so I flashed back to complete stock. I did notice a tiny bit better life on some of the roms. O and I have factory reset before as well as wiped cache. They'll probably do a insurance replacement but I think the warranty one is only once. I think there's a deductible for the tmobile insurance replacement too but whatever I'll give it a go.

Deductible is only if it's your fault, like breaking it or getting it wet. If something is wrong with the device, like manufacturing defect, the most they should charge you is about $5 and you get a replacement shipped overnight

Crazy lol. Maybe I did something during root? First time I ever tried I messed up and got the phone stuck in bootloop. I managed to fix it and get rooted and tried out several roms for a week or two. Then went back to stock once the latest update was available.

Is that on a single charge?

No that's over very many. Stats never seem to reset, it just keeps going up on that. EDIT: Ah it's finally reflected and gone down to 5% in stats. Actual feeling of the time still seems to be the same though. EDIT 2 : The stat is climbing again even while in airplane mode. Screw this phone lol.
I have a T817T (T-Mobile Tab S2 9.7") that gets about 20 hours of battery life with the screen off and nothing running. Bluetooth, and location are off. Airplane mode enabled to try and prevent it from search for a mobile network. Wifi on and connected though. AccuBattery is show a screen-off discharge speed of 238.5mA.
I have another Tab S2 that is a 8.0" wifi only that will last nearly a week with screen off an no use. This one shows a screen off discharge of 12.0mA.
Of course, the larger tablet screen would be expected to draw more, but a difference of 20x with the display off is excessive.
I don't have any mobile data service plan on the 9.7. Could this be causing it somehow? Like if the tablet is constantly trying to connect to a mobile network? If so, is there a way to disable that? I was wondering if rooting/flashing a custom ROM might be able to help me identify and fix whatever is draining the battery so much. I haven't rooted anything since probably 2011 or 2012 though, so I'm basically going to have to relearn how to do everything.
