Bought a new Digitizer/LCD off ebay a few months ago and installed it myself.
Question is, could a new Digitizer/LCD be draining my battery more than usual?
I would say its possible, but those screen shots don't appear to fully support that. The way I would analyze that screen shot would be to say turn off wifi and see what a day without wifi looks like. You can see only the little amount your screen was on during your steady decline, but wifi was on constant.
Edit:
The drop doesn't seem to spike at the points your screen is on.
Its very routine for me to use Pandora (on 3G) with a Bluetooth headset for a few hours with my screen off, and have it show the display as the largest drain.

Okay, I am charging up right now and going to calibrate my battery tonight. Should I turn off Data too, tomorrow? Or just Wifi?
Not sure what it is...or what it does, but is it after market or Samsung.

It was from another Cappy. Basically, it came with everything but the guts (Motherboard, etc).

I thought you could only replace with a Samsung AMOLED screen, due to proprietary connections.
My guess would be the screen came from a bricked or otherwise incapacitated Captivate.

Then I'm guessing, as long as it was installed correctly, it's not the cause of the battery drain. Recalibrate, and give it a couple of charges. At least 3.

I would think the same. But this wouldn't effect the battery life, would it?
I mean obviously I put it together right if everything works with it?

Trying both couldn't hurt. But for the truly scientific approach I would do it separate. Like data on, wifi off one day, next day both off, and finally a day of airplane mode. If you can live without it for a day. Just to try to pinpoint where that drain is.

Yeah, like Joe said, I could see it throwing off your calibration, being a new screen to "learn", but I wouldn't think it is really drawing any more power than any other screen would.
Plus you are using GB, and GB is known to have battery issues. I can't get the old Froyo bump charge tricks to work in GB, it just took several power cycles.
Maybe you should start there (instead of days of trial and error as I previously suggested)... how long ago did you replace the screen?

What do you guys think? Isn't it weird how much battery my screen is eating up?
It does look like the screen is the cause from those shots, though there can be other things that turn on when the screen is on.
Just to be sure, have you tried changing the screen brightness? You might want to try setting it to the lowest setting for a time, then change it to the highest and compare.
What is that notification from? Looks like the juice defender one (i could be wrong, probably am, it was a long time ago that I tried it). If that's what it is I would try a day without that. When I used it it caused massive battery drain, essentially the opposite of what it's supposed to do.

My house has terrible reception in general (T-Mobile!), but I've never had a phone drain THIS quickly due to searching for signal.
I've set it to 2G only (I only get EDGE at my house anyway, THANKS OBAMA) and it seems to be helping.
Is the Nexus 5 or Kit Kat in general aggressive with searching for 3G/4G signal in anyone else's experience?
Like I said, other phones haven't had this issue.

I have this SAME problem, and the signal on my phone is terrible compared to my last LTE phone.
same problem at work...... I dont know how 1 place can go from lte to 4g to edge all with in a small building with 1 floor. First day while being at school i got 3 hours screentime on lte, today at work i got like 1.5 hours.
27% over 12 hours with one bar seems just fine to me..

Mine reacts different with st att. I get 1 bar of lte in my home when I force lte. If I do auto switch gsm/lte it opts to 3 to 4 bars of hspa, which of course I prefer at home on Wi-Fi.
I've used tmobile for most of my smart phone life and always used tasker to switch to edge when connected to Wi-Fi. Saved a lot of battery. So your experience has been what I normally get.

I have T-mobile as well and my house is in a bad spot. I found that with my note 2 I could use the dialer debug codes to manually set the phone to what ever freq and service I wanted. I found this to greatly help my battery as the modems for T-mo are particularly bad at determining the correct type of service to use and needlessly killing battery.

At least I'm not alone. It's just annoying to have to switch to 2G only when I go home. -.-

Are you guys using wifi while at home? If not then you really should. It generally makes the data modem go into a lower power state if wifi is connected saving battery. Thats how it is on my VZW galaxy nexus.

I do use WiFi at my house.

I have full data bars in my area. If I turn WiFi off and just use data the battery drains significantly faster.
I am new to T-Mobile, I was with Verizon and my house on Verizon barely gets LTE. My galaxy nexus never got LTE but with T-Mobile my Nexus 5 has 3-4 bars of LTE. So I've been using LTE lately and my battery life has been great. I get 5 + hours screen on time with LTE.
Of course Verizon says my area has great 4g service too but anybody who has came to my house either gets 1 bar of LTE or 3g on Verizon. Trying to acquire a signal will of course eat battery though but I will tell you what I am very happy with T-Mobile so far, a lot better then I expected.
I am happy with the battery life and signal strength where I live and travel to.

Like I said, manually switching to 2G-only when you're in the affected area removes the problem, but you'll need to switch it back to LTE when you go anywhere with a better connection time. Settings > More > Mobile Networks > Network Mode.
If you're worried about battery life. There's a few things you can do. I found that turning off my "Ok Google" hot word detection increased battery life immensely. Also try turning off Google Now sometimes. I realize that the highlight of this phone more or less was Google Now, but if you don't need it for a certain period of time, turn it off. Doesn't hurt to try.
Try out Faux kernel also. On his test 7 (I think he just put out test 8) I was on track to get 60 hours of standby time. I'll try and dig up the screenshot..hopefully I didn't loose it one of my many wipes..

I had this problem and I sent my phone back and got a new one. The new phone doesn't do it at all just got a day and a half with over 4 hours screen time. I think some of the nexus 5's are a bit dodgy.

Yes. Sorry, I had flashed both kernels and decided on Franco for now because it seems he's had the most progress so far. He also received his own device today so he should be able to get even more things done!

+1. It looks like my N5 gets 5-8 dBm worse signal than my N4.
I have been using my N6 for the past couple of days and the battery life has been quite disappointing for me so far. It seems the biggest culprit for me is the poor signal in my area leading to a huge amount of drain from Cell Standby. Even when idle, my battery drains quickly. I lose 1% every few minutes without even turning my screen on and about 10% over an hour. As of now, my device has been on for 2h 49m and 24% of that time has been without signal.
I understand that poor reception is causing the radio to constantly look for a signal but my Moto G and Nexus 5 are in the exact same environment and fair much better when it comes to battery life. Anyone else experiencing this insane battery drain? At this point I'm debating sending the device back, getting a refund, and dealing with the bloated and Touchwiz filled Note 4. It's a bummer because I absolutely love this phone otherwise. The screen, build quality, WiFi signal strength, and audio experience make this phone an absolute delight but the battery drain might be a deal breaker for me. Thankfully I still have a couple of weeks to make up my mind on whether or not I'll be keeping the phone or returning it and going for another phablet. Thanks to the N6, I can no longer return to a phone with small display.
As I mentioned earlier, I am not having this issue with my Moto G or Nexus 5 and both devices have excellent idle battery life.

This seems to be an issue with Lollipop and people with the Nexus 5 are also experiencing this. There is a thread over at /r/android discussing this issue.
I absolutely love this phone and I will be holding out for a patch as long as I can. This phone is so awesome though.
I don't have this issue with my new N6 or my N5 on lollipop. I have very strong signal though in my area.
I would like to point out though it's not that bad considering your without service for over 20% of the time at that point.. From that it looks like you'll have a12 hour day.

This cell standby drain reminds me of eclair and froyo days. I believe the temp solution for this was to briefly put it into airplane mode. Then turn mobile network bank on. It would sort of reset the existing bug. Anyone remember this from way back when?

Just a thought.. try changing it from LTE preferred to 3G. I'm not saying to use this as a permanent solution but just try it out. I was in the -90 to -103dB range in signal on LTE and it would randomly crap out entirely for a few seconds every couple minutes (at best). I have no idea why - didn't have that issue on my older galaxy S3. Anyway, switching to 3G suddenly gave me fantastic reception (at least in terms of signal strength).
If it helps you - that might be the cause of your battery drain: poor signal.

Like others have mentioned, forcing it to a specific network mode will typically save power, especially when you kill something as power hungry as LTE.
From the regular system menu, you only have the options to set "preferred" LTE/3G/2G, but this does not actually disable LTE or 2G when you select 3G.
From the dialer, enter *#*#4636#*#*, select phone information, scroll down to "set preferred network type" and choose "WCDMA only". With this, it will actually turn off the LTE and GSM radios.
From the Android Central forums:
Settings. . Mobile networks. . mobile data .. enhanced 4g
Since turning off wifi also stops the drain, I might speculate the bug is actually in the voice processing for wider bandwidth and turning off wifi or enhanced 4g shuts down that section of voice processing, which is keeping the radio alive when it should not.
Thanks for that. I'll try this..
Does enhanced 4g mean LTE? What does turning it off do (besides save battery life supposedly)?

Thats HD Voice (AT&T's version of VoLTE). Turning it off disables the Voice over LTE feature.
Does anyone have proof that this is related to cell standby? I am skeptical that this is the smoking gun for battery drain. I have noticed a substantial drain even compared to my old Moto X (2014) and that is saying a lot since that phone's battery wasn't great. I am trying to see where we can make stride to determine the reasons for it. I have different results in my details. Sometimes android system is the culprit.
I turned off Enhanced 4g last night and cell stand by isn't even on my battery usage list today. It was the top one last night before disabling.
How's the overall life now? I just shut it down myself.
Anyone do this and leave WiFi on and still have good battery. Seems to me that no matter what I do WiFi still causes the battery to drain far faster than it should.

I switched off enhanced LTE but if I leave the wifi on I see a battery drain. With wifi off I get a stable battery. My Edge (AT&T) is on Android 5.0.2.
I remember first T-mobile users mentioning battery was ok until 5.0.1 which was later updated to 5.0.2 and the trouble started.
If we could just figure out how to get rid of Google Play services
Im gonna try this too. I keep wifi on. Time to charge up to 100% and see how quick it goes down
So today I decided to keep wifi on and wow. Battery life not as good. Not having horrible drain, but it is most certainly effecting my battery life. So tomorrow I will go all day without wifi and see how it fairs. But I'm thinking that unless I know I'm gonna be at home a lot where I can easily charge, then wifi will remain off indefinitely. Good thing I have 30gb mobile share data

Or perhaps one could turn it off halfway through the day & extend battery life.. Lol idk ?
BGR are a bunch or turds, they are iCrap homers and are the absolutely the worst. BGR is a great example of what is wrong with journalism and yahoo today, 2-3 paragraph hit jobs without any research. They just scan xda forums or other news sites for the most popular "problem" threads and then write an anti-android article almost instantly.
With that being said and considering the source, no this is not a possible battery fix .
Apologies for going off, but if you couldn't tell, I really hate BGR and yahoo.

Well that's not a fix its a workaround (I hate VoLTE anyway). I have both off but when I'm in a building with poor to no reception it eats my battery worse than any phone I have ever had. Plus there's no way (I think) the memory leak is causing my battery to drop like it is when it's doing absolutely nothing. I don't have any apps like facebook to cause it either. People on reddit who have taken the 5.1.1 edge leak say the difference in battery life is biblical so we will see if that helps me when we get it.

Hmm. Since I've moved to the Edge (since my first S6 was defective) I'd love to see the improvement. I went from getting 9-10%/hour drain with very little use on my S6 to about 3% with moderate use on the Edge. I'm at 8 hours on battery and 1hr 15 of SOT and I'm still at 75% battery life. For stock, that's pretty good IMO.

I keep hearing across all of the Galaxy S6 threads how the 5.1.1 update will fix battery and voLTE and Wifi calling issues... I hope it does. My question is when is the predicted date when Tmobile pushes it out to us?
I have had my S6 for a little less than a week, and it's completely stock. Rooting (in any of the multiple ways) seems to have issues with deep sleep, but easy work arounds. I plan on keeping it stock for as long as I can stand, but if Tmobile isn't planning to push the 5.1.1 out in the next 2 months, I will root. Plus, the opportunity would be present to clear out some bloatware
