Battery life in the last few days

Anyone notice a change in their battery life in the past few days? My girlfriend and I both are going through our batteries in just over half a day with no use. It's like the phone isn't sleeping. Looking at battery use Display is using all of the battery. I'm running CM7.0.3 and she's on stock. Looking at mine right now the phone has been on battery for 1 hour 34 minutes, and Display is taking 57% of the battery and I'm down to 84% battery.

Yes! I've had my N1 since January 2010. I stayed stock until recently when I installed CM 7.1 RC1 shortly after it was released. Battery life had always been great, both stock and under CM7, especially with SS4N1. Then, a few days ago it just fell off a cliff. I now get only about 7-8 hours, even with little to no usage. Before I'd barely lose anything if the phone wasn't being used (a percent every couple hours).
Now the Nexus One Battery Calibrator application shows a drain of ~200 mA or more constantly.
I've been tearing my hair out for the last few days, uninstalling apps right and left, trying in vain to figure out what's causing this. I even considered a full wipe and reinstall of CM 7, thinking that some system setting somewhere had gotten horked.
I've always had WiFi set to never sleep, since I'm usually either at work or home. I've also had preferred network type (*#*#4636#*#* -> Phone Info) set to "GSM auto (PRL)" for months.
I've not made any other changes I can think of that would've had such a drastic impact on power consumption. I didn't track all the app updates that happened around the time it started, so I suppose it could be one of those. But I've uninstalled just about everything and it's still happening.

I have the same issue! Just in the past week or so. I have about 50% battery then a hour or so later it's dead! I was going to get a new battery today but maybe it's a CM7 issue. I use the nightly as soon as they hit the mirror.

An update on this... There may be a big issue going on with T-Mobile or some recent update:
http://www.tmonews.com/2011/07/t-mobile-g2-users-suddenly-suffering-from-huge-battery-loss/
Looks like other users on different phones have the same issue!

Thanks for that article, Lost Dog. Makes me feel a bit better. At least I know I'm not just going nuts.
My phone still has increased battery drain even if I put it in airplane mode though. It helps, but it's still much faster than before. This makes me really puzzled as to what the cause could be. How could the cell network still be causing increased drain if the phone's completely disconnected from it? Some sort of configuration information it received that persists even after the cell radio is turned off? EDIT: I may be wrong on this one, see below.
Last night I tried a complete wipe (using Temasek's full format "Format-signed.zip" first), and re-installed CM7.1 RC1 completely fresh. I installed only the minimal Google applications and a couple crucial tools (my password safe app). However, I'm still getting the same quick battery drain today.
I hope we (or T-Moblie) can figure out how to fix this. It really cripples my phone as a useful tool to have such short life!
EDIT: I'm going to try a workaround I've seen mentioned in comments on the TMoNews and Phandroid articles about this: limiting the cellular connection to 2G/EDGE only. It seems to have made a significant difference so far. I may have been incorrect then about airplane mode not having an impact. I'd only been checking current drain with the N1 Battery Calibrator app, and never left it in airplane mode for long. Anyway, I'll post back later this afternoon with results.

Ok, so switching to 2G-only for the cellular connection seems to have made a HUGE difference. The drain rate seems to be back at around what I'd expect. Everything else I left exactly the same (WiFi on, GPS enabled, same applications, etc.)
So, I'm starting to suspect something may be up with T-Mobile's 3G/3G+ service in some areas that's preventing phones from idling properly.
Anyone else want to give it a try?

Interesting, I'll switch over to 2G only and see how that affects my phone.
I've gone as far as wiping everything and that didn't help so if it really is a t-mobile issue then that would shed some light on the situation.

I see the same trend when switching to 2G only. Very steep power usage with 3G then a dramatic decrease in the discharge slope in 2G.
T-Mobile has an issue. The trick will be getting someone there to listen.

Here is my screenshot. You can clearly see when I turned on 3G. Dramatic difference. Looking on the T-Mobile forum there are many people seeing the same issue but there's mostly finger pointing and speculation as to the cause.

I also got the same rapid battery drain since last Wednesday. At that time, I thought there may be a hardware/battery issue for my nexus one. To test this, I switched my rom from CM7 back to GB stock. After a few updates for the GB stock and used it for a day, same battery drain happened. So, I changed to use another backup battery yesterday. It did not help also. I thought it may be a real hardware issue.
Then, I found this thread and research a bit in the web. I found out it could be either caused by tmobile or google map updates. I first uninstall google map and reinstall the new version right from the market again. I also switch off 3G as well. No rapid battery drain for the entire day. The battery runs normally. When I came back home today, I turned on 3G, let it for a couple of hours, checked a couple of emails and received a 20min phone call. Everything seems to work fine. No noticeable rapid battery drain was observed. My conclusion so far is: this is caused by google map 5.8 update.
Try to uninstall it and reinstall the google map from the market to see if it helps.
Good luck.

Well, I'm willing to give it a try, but I'm skeptical. If it were the Maps 5.8 application that was preventing the phone from idling correctly, or transmitting tons of data, wouldn't we expect it to happen regardless of whether the phone was using the 2G or 3G radio connection? Sure, there might be a slight difference in the drain rate, but we'd still expect to see it in both cases. And yet the accelerated drain is alleviated completely by using only 2G. I have the Maps 5.8 application and can fix the problem by using 2G only. That indicates to me it's not an issue with the application.
I'll try uninstalling Maps tomorrow (I'm using CyanogenMod, so it's possible to remove it completely). Then I'll put the phone back on 3G and report back on what happens.

I've been experiencing similar battery issues the past week or so too. It looks like turning on 2G only seems to fix it, but what I don't get is why I'm still getting horrible battery life?
I have tasker auto turn off my 3G all together whenever my screen is turned off, and yet I leave my phone on my desk untouched all day and I end up at 40% when I get off work.
Wouldn't turning off 3G via Tasker be the same (or close to it) as turning on 2G only in the settings?
Hope t-mobile gets this worked out pretty soon!!

Glad I saw this thread. My wife and I both have N1s and have each been noticing unusually fast battery drain just in the last 3-4 days.
Last night I charged both phones to the same percentage, turned off 3G on hers and let them both sleep for a while. The phones are configured pretty similarly (stock, latest Maps installed, similar push settings etc). After about an hour and a half, my phone had lost 11% of its charge and hers had only lost 2%. That's enough of a delta for me to point to the 3G usage as the culprit. I guess I will be leaving my phone on 2G when I'm not using it if I am going to be away from a charger for a while.

It's NOT the Google Maps update.
Well, I did my experiment yesterday to rule out the Google Maps 5.8 update as the cause of this issue.
I'm running CyanogenMod so it's possible for me to uninstall Google Maps completely, not just the updates. I did so on Saturday night. Still set to 2G only, I removed my phone from the charger Sunday morning. A few hours later I enabled 3G. Later that afternoon I turned 3G off again.
I think the screenshot speaks for itself. Again, this is without Google Maps installed at all.
I asked around this weekend, and my friend's wife (also here in Portland, OR) is experiencing the same issue on her G1 on T-Mobile. Reading online I've heard about the problem affecting the MyTouch 3G, the G2, and many here with the Nexus One. The common elements seem to be: T-Mobile 3G service, particular models of phones, and some particular geographic areas.
Bottom line (IMHO): T-Mobile has a problem with the configuration of their 3G service in some areas, and it's preventing many phones from being able to idle/sleep properly, resulting in huge battery drain.

Here's mine, I posted this several days ago in the TMONEWS thread.

That's interesting. Even locking the phone to 2G/EDGE didn't have an impact? (not a Nexus One there it appears, what model?)
How did you go about disabling the 3G connection? I'm not sure if there are multiple ways to do it, but I used:
Settings -> Wireless Networks -> Mobile Networks -> Use only 2G networks
Really strange that even pulling the SIM didn't seem to make a difference. Or maybe that's not the same as turning off the cell radio entirely? Perhaps the issue is lower-level, like the radio constantly polling the tower or something even in the absence of being able to successfully register on the network for active use.
Does enabling airplane mode fix the drain issue for you?

This is a G2.
2G has been much better than 3g, but still probably only 3/4 of my former battery life, optimistically. I checked "Use 2g networks only", same as everyone else. The graph above is a little misleading, since I really saw better battery life, that initial flat and quick drop actually averages out to "decent", rather than "horrific.
At the "Pulled SIM and SD card" mark I re-enabled 3g, so the drain afterwards is still 3g related.
Pulling the SIM doesn't disconnect it from the radio tower, you can still make emergency calls/etc. so it has to maintain a connection I suppose.
Twice I hard-reset the phone, pulled out SD and SIM, and still had huge huge battery drain. Powertutor said IDLE draw was 1437mw on average, no SIM, no WIFI, just sitting there on my desk.
In Airplane mode it'll last for days...

I'm not familiar with Tasker. However, maybe it's just disabling cellular data use, not actually disabling the 3G radio? From what we've seen it appears the problem is very low-level, perhaps something to do with basic communication/negotiation between the cell radio in the phone and the towers, as there's no indication of particular application activity or significant data transmission that the Android OS is aware of.
In the T-Mobile support thread there are reports that T-Mobile is now acknowledging there's an issue with changes to their HSPA+ network in some areas.

I've had 3G off all day and my battery life is back to normal. I'm at 87% after at least 6 hours on battery. Yesterday I was down to less than 50% by this time. Luckily, I am able to be on Wifi at work so I don't have to deal with EDGE speeds, which make the Baby Jesus cry.
deliamber, you probably noticed this already but I'm also in the Portland market. It's gotta be a network issue.

I'm having the same issue on my N1 (I'm around the Portland area myself)
I did everything as well, 2g is the only thing that saves me..
Can't wait for a fix!

New IPC Wakelock

Just started getting this a day ago. All syncs turned off, most Samsung apps frozen, literally nothing extra running in the background and can't get rid of this wake lock. No search results on it either, any idea guys?? Phone went from 100% to 64% overnight from 2am to 8am because of this. Won't stay in deep sleep.

Same here. Just noticed this yesterday. Been searching and have found nothing. BTW, I'm 100% stock (not rooted).
Update 1:
Been playing around with basic settings.
Turned Wifi off : No change (IPC still running)
Turned GPS off : IPC stopped running!!! Still too early to tell, but is your GPS on?
Update 2:
Turned GPS back on : IPC did not restart (phone is now deep sleeping)
Going to turn Wifi back on ......
Update 3:
Wifi back on and IPC did not return. Hmmm, gone for now, but for how long. Still try turning off GPS as that is when it stopped for me (and has not returned even though I have turned GPS back on.) BTW, GPS was not showing as a battery drain while IPC was, it could have been coincidence, just documenting what I've tried.

Problem happened again this morning.
I turned GPS off, problem stopped.
I turned GPS back on and the problem did not return.
Still no root cause, but when it happens, cycling GPS seems to stop it (at least temporarily.)

Glad you found the solution. I finally gave up and just wiped my device because it was draining too fast. Will definitely use your solution in the future if it reappears

My battery life was running perfect, I even bragged about it to friends then all of a sudden a few of days ago, I face the same exact issue. Until now, I can't figure it out. I already did 1 clean wipe (factory reset) and everything seem to be ok for 22 hrs. Then out of nowhere, Wakelock ipc00000024_er.serverthread starts sucking my battery dry all over again. I tried toggling GPS and Wifi but no luck as it's still running in the background. I'm not sure if it's an app causing this or if it could possibly be from turning off a lot of bloatware?

I bet the option circled in my pic was on when you had the problems, right?

Definitely not on or checked and I rarely enable GPS.
I haven't installed any new apps to my phone recently. Only 2 things i've done right before this started happening was 1. unlock my phone 2. turned off and force stopped dozens of ATT bloatware.

Hmm bizarre man. I am not rooted but I have been getting excellent battery life with that box unchecked but with GPS actually on.

I am getting this wakelock as well. Happened after I froze some stuff, so I'm going to experiment.

l was getting this wake lock as well and noticed that in battery stats, the GPS was showing as always on despite every location option being turned off.
After reading up a bit, I uninstalled the task killer I was using. I think some program put in for a location hold without specifying a timeout for releasing it. The task killer then abruptly killed it, and the lock was never released.
Everything seems back to normal now after the uninstall and a reboot.
Hope this helps somebody.

After factory resetting my device it went away. Now after two days of not changing any settings it is back

I too continue to randomly suffer from this problem. I'm finding that cycling GPS does not always work (neither does rebooting).
These "Android OS" wakelocks drive me crazy, its not "Android OS." can be uninstalled.
I'm still fairly convinced that it has something to do with Location (GPS). Could be weather, Google Maps, Google Now, ...

And this is back again. Does anyone have this?
Seriously I am not even installing apps from the playstore. After around 3 days it randomly comes back and doesn't stop. it consumes about one percent of battery every 3 minutes according to BBS. Thinking about selling the phone because of this.

Have you had any luck with this?

I just got back from a 1 month trip to Thailand. I took out ATT sim card and popped in a local SIM card by True Mobile with only 3G support. I had zero battery issues and no Wakelock ipc00000024_er.serverthread for 1 whole month. Now that I am back from vacation, popped in ATT sim card, Wakelock ipc00000024_er.serverthread is back in action draining my battery at a rate of almost 10% per hour. (Running stock with most recent ATT OTA update)
I wonder if this issue is directly tied with 3G/4G or SIM card use?

The issue was never resolved. I ended up rooting and installing x-note rom which is currently running flawless. Smooth as silk, no ipc issues and battery life is insanely awesome. With stock battery i'm running 24-29 hrs moderate to heavy use. With my hyperion extended battery i'm running 48+ hours with atleast 10 hrs screen time. No battery drainage or non sense wake locks on X-note rom.
If I were you, i'd ditch the ATT stock rom, it's night and day.

I just started having the exact same ipc00000024_er.serverthread wake lock and I can't find a solution. Newly rooted, so I don't know if that has something to do with it.

There's nothing you can do if you're still running stock. I've tried to solve the problem for months.
Go install a custom rom, X-note 7 is badass. Kiss ipc000024 goodbye!

I was having issues with this wakelock as well. Toggling GPS on/off fixed it for me. Perhaps Ingress was locking the gps position... dunno.
---nevermind, it returns after a while just like the guys above mentioned---

Battery issues are killing this phone for me

So, I really love this phone. Despite not being able to get it sim unlocked yet, I find that I'm even more satisfied with it than I expected. There's just one glaring issue: Battery drain, specifically at idle.
I have tried everything: Uninstalled/disabled all apps that I didn't need, used App Opps to turn off "keep awake" for just about everything that I could. Nothing works. Last night, I left it off the charger with 100% and 8 hours later, it was down to 50%. It loses 5-7%/hr at idle without doing anything at all. I'm in a high signal area. I tried charging it to full and turning off wifi. That had no effect either.
I'm seriously torn between wanting to return it because I can't even get through a single day on a charge and really wanting to keep it because the camera and screen are so awesome. I'm sure there will be an update down the road that will fix this and I don't think my device is defective. This drain definitely isn't normal.

Do a hard reset and see if that works.
If not take it in to tmobile, do a hard reset there And let it sit for 20 minutes and show them the idle battery drain.

I'm not wiping my brand new phone that has been doing this since I pulled it out of the box. A hard reset is not the answer to everything. There's definitely something wrong with the the software build.
It's my fault, of course. I should have added "in b4 do a hard reset" at the end of my post.

I know it sucks but try and tough it out. There is a massive issue relating to WiFi on this device right now. I am doing some testing but I think proof can be found in that when you turn off WiFi but WiFi calling was enabled in the dropdown you will fail to get cellular signal back at all. It will stay "Searching" all the time.

Yeah, I have tried leaving Wifi off completely, but I'm still draining pretty fast. The problem is, the phone is almost unusable for me like this because I can't even make it to the end of the day if I use it at all. And since I rooted, any update they release is going to be a pain to apply.
I blame 5.01, to be honest. The best thing Samsung could do is rush out a 5.1 update.

Same thing was happening to my phone out of the box as well, something was keeping it from deepsleep, did a hard reset, put all the same apps on. Now it sleeps like a baby.
I should note that battery life still isn't great but it does last me through a whole day, still getting high cell stand by drain.

Go to this thread http://forum.xda-developers.com/tmobile-galaxy-s6/general/discuss-battery-problem-t3071622
and self-diagnose and help us find a workaround and/or the source of the problem!

Glad to hear the factory reset seems to be working. Let's work together to try to narrow this down and not result to attacking each other

From the Moderator
OK People, Cleaned this chaos and trolling.......
Post respectfully or ........DO NOT POST........... easy
To your battery issues......... these issues are pretty much the same with all phones, so the fixes are pretty much the same\
Hard rest
Go into the menu and disable apps that are pinging GPS
Freeze apps that you do not need -if you are rooted then use titanium back up to freeze or other app that does the same - if you are rooted I would disable any updates from the Carrier or Samsung- that means disabling the patches/apps that control those.
Turn off WiFi and Bluetooth when not using it
Avoid leaving social media apps running in the background they can be battery hogs.......
This is what was recommended in 2010 ........... still pretty much good advice ........
The next person that posts disrespectfully or trolls will be met with an infraction
Keep kind and civil and ON TOPIC ONLY
Thanks ~~~ oka1

I have had zero problems with this phone's battery, but then again I always factory reset after an update. Got the 177MB update, installed, FDR, and butter ever since.
I get about 6 hours SOT with heavy use.

Dude, I was having the same exact problem with my S6. First, I disabled all of the apps I wasn't using. Next, I turned off wifi-calling. After that, I turned of VOLTE in the phone app. Last I backed up my music, pics, contacts, and sms's, and done a hard reset. I restored my stuff and completely charged it up. Now I am only loosing about 1% or less an hour at idle. I charged it up at 12, left it sitting and 3.5 hours later it's on 97%. That is quite an improvement for me as my S6 would be below 50% in the morning if I left it off of the charger over night for 6 or 7 hours......Just my two-cents to try and help. Good luck bro...

I wanted to add that this didn't start happening to me until after the OTA was installed, before that, it was good to go for a whole day so the OTA does something to knock things off track.

How do you do factory reset? When I go into settings-backup and reset, hit reset- it gives me the warning and I proceed then the phone just shuts down, and nothing happens.
Method 2 - I power off, then hold vol up, home and power, until this logo comes up and then it goes black. I am strating to think that there is something wrong with my stock recovery.
thoughts?

Did you try to root at some point?

Is the issue with Cell Standby affected all T-Mobile Galaxy S6s or only a few?

Haven't several people said that the Cell Standby issue only started to appear after the update? I would wait on the update a bit to see if you have any battery issues just for the sake of knowing. Then update and see if it makes a difference.

It's not the update. The problem is VoLTE and WiFi calling. Turn those off and it goes away. I'm on the update and have no high cell drain since doing that.

5.1.1 Battery Drain

Is anyone else having huge issues with battery drain after updating to 5.1.1. I've disabled all the crap, wiped my cache, disabled enhanced LTE. and have minimal apps installed besides stock. Just took the phone off the battery charger. It was at 100% when removed. It's been sitting for 40 min with the screen off. The battery is down to 93% already with 3% being used by Android system, 1% by system UI, and 1% by Android OS. This is nuts. I can't even get through 1/2 a day of regular use. Any ideas?

Big time. My phone isn't going to sleep. My Android System Stay Awake time is more than double my screen on time.

I'm having the same problem. I currently have Location History turned on to get more surveys on Google Opinion Rewards (I could turn that off if I wanted to); and I also know that because I'm not in WiFi during the day, the Lollipop mobile radio active bug keeps the radio awake way longer than it should. It's crazy that I can leave my phone alone during the day and watch it drop ~5% an hour because of the horrible standby behavior.

There is something wrong with your phone or app. I have about 100 apps. No problem here.
This is the international version of the phone

Or it's something to do with the AT&T version of the firmware as yours is an international version and not having issues.

Battery drain issue is related to the AT&T 5.1.1 firmware.

Complaint to att to stop messing with a perfectly fine phone. I haven't turned anything off and that's my idle time.

I guess it might make sense to stay on 5.0.2 in hopes of a future bootloader unlock and to stay away from a potential battery draining bug. If only AT&T would embrace a more open approach to this model phone. I only got this phone because the nexus was out of stock and I was in need of a new phone. My trusty old S3 was a godsend, with its unlocked bootloader and fully open platform. The fact that AT&T is closing up the ability to root the phone is drastic enough, let alone introducing bugs that make you want to throw the phone at the wall (battery drain).

How can I see what is keeping my phone awake without root? It's staying awake 3/4 of the time and below is a shot of my app usage. What I can tell it's a system issue, but not sure. And yes I factory reset twice and wiped cache.

Same here. factory reset cache wipe x2 and have everything non essential disabled. It's driving me nuts! This phone was a rockstar until this update. Going to best buy tomorrow and will see if the Samsung folks can reinstall the update or something. I'll post what I find out.

Battery life is worse than my old s4. The screen barely takes any of it, when it used to be more than half the battery life on my s4. Yet I still get about the same screen on time.

Yup I completely agree. Left my phone at 53% overnight and I woke up to the phone completely drained and dead. It's ridiculous.

I noticed something odd. On wifi, battery life is great, maybe 1% every 2 hours idle. But without wifi, battery life goes down 10% an hour idle.

Finally made it to the Samsung center at best buy. The guy was able to force the update again and everything went smooth. So far maybe a little better, not sure yet. I'll post when I know for sure if it worked and was a bad update.

So after the forced re-do of the update it wasn't any better. List 20% at night with everything off. Dido another factory reset and cache wipe and that seems like it might have fixed it. Only 4% list last. Not as good as it was but definite improvement. Hope this helps anyone else with same issue.

TurboRZR please update... would love to know if that fixed it before I wipe my S6 for a second time.

I too am having an issue with the new 5.1.1 update where my "Android System" is getting stuck in a stay awake loop draining my battery. Sometimes a simple restart will fix it for a few hours, but it will always come back.
I installed wakelock detector and set it up to run on a non-rooted phone. When I pulled the statistics , the biggest battery drain I had under "Android System" was diagnostic.client.network. Nothing else even came close to the drain this resource was pulling.
This was as far as I was able to get as I have no idea what that is or how to disable it if I even should.

I have resolved the issue on my S6 Edge, I even attempted a factory reset which didn't resolve the issue. I had noticed my Wifi usage in GSAM was very high (50-70%) and after some searches I found that someone else posted in a different forum (I think it was the S6 Active forum) that the issue was related to multicast being enabled on wifi routers. I disabled it on my fios router (it's in a hidden menu) and it resolved my drain. I am now at 12 days uptime without a random drain. I also had to disabled Enhanced LTE as that was causing a HUGE drain at times when I didn't have LTE. I hope this helps.

Cell standby

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
Sent from my SM-G920T using Tapatalk

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
Sent from my SM-G920T using Tapatalk

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.
