Hello,
I've experienced a sudden change in battery performance.
What used to take around 50% of battery now takes around 85%.
It happened recently, around the same time I started working at a new workplace. The reception is horrible there, maybe that's the issue. However during the weekends, it is around the same.
I was on 4.4.2 stock when it happened and since then I've flashed it again once. I've also tried a couple of different radios (and enabled LTE) and I've always had franco kernel.
Brightness was always on Auto (which I shall turn off to experiment battery life) and wifi is selected to be off when the phone is off.
I have still a few more experiments to do, but I'm considering using warranty services. What do you guys think? It's clearly not as bad as some of the other battery issues I've seen on this forum, but it's quite the change for me. I bought this phone in July 2013.
Here is an example battery usage graph. Charging finished around 1 AM and left it unplugged over night. In the morning (~7 hours) the percentage was at 75%. (5% / hr) Throughout the day, I have used it for text messaging only and by 6 pm, it's at around 13%.
Thanks for taking the time to read my long post.

You can check what drains battery with BetterBatteryStats. Google it and you'll find.
Thanks for replying.
I have tried that before an OS reset although I couldn't make much out of it. One main thing I noticed was a certain kernel wakelock which, after I googled, was responsible for LTE connectivity. Although this makes sense, I had good battery life even with the LTE chip being used (& auto brightness / wifi always on) prior to this battery incident. By good battery life, I mean 50-60% used by the end of the day

Been about 2 hours since unplugged and been on 3G, played maybe 5 minutes of Angry Birds, 2 emails, 2 2 minute phone calls, few texts and browsing the android market for about 10 minutes. I'm now at 84%
Compared to the rest of you guys out there, what would you call this? Eh, so-so, decent, great, outstanding? So far anyway.
Keep in mind my RADIO and PRL have not been changed from factory since the phone has been switched over to Boost Mobile and I don't wanna lose settings since I had to pay to do so originally.

Check your Display on time, divide that by 2, add number of hours off a charger. That's how many percent of battery you should have used since unplugging (with average use between, calls, web browsing, texts, game playing etc.)
In other words, using display/cpu (with autobrightness and apps which don't consume ridiculous amount of cpu time, like 3d games) consumes about 0.5% per minute. The standby usage with 3g on will consume <1% per hour.
Anything larger than those figures, and you have a problem.
I got it. Does the Display on reset itself once a charger has been plugged in? I originally took my phone off charge around 1:10 this afternoon, plugged it in for a very brief moment (2 minutes) to put a .apk on my SDcard. I noticed my "time since off charger" reset, so does the same apply for the Display?
So it does. I'll do a full charge over night and report back.
does your 4g connection work? or you get a sprint web site?
My note 3 battery is horrible I downloaded wake lock

Here is another
My phone has been in my pocket all day not being used until just now when I made this post
I should also mention it is fully stock
looks pretty standard for stock to me. 5 hours for 23% of the battery? That means about 20 hours a cycle? seems very standard for stock.
If you want more then you gotta go custom ROMS and Kernels.
If your rooted use SET CPU to make phone clock speed 322-400 mhz when the screen is turned of.
But why is it awake so much?
Search for "AndroidOS Bug" and you'll get the answer.

This bug really makes it hard to enjoy the note 3 as a whole. I was plagued by this pretty badly until recently I sort of found a workaround.
Some time ago I found out, that in offline mode the bug is not present. I came across it, when i was in our datacenter where the cell signal is a nightmare. I turned on offline mode and switched WiFi back on (thankfully we have a WiFi active there) and the battery drain was very low with active WiFi and bluetooth (headset connected) over a period of several hours.
I did still encounter the Android OS bug afterwards, but then once after my phone was fully charged, I put it into offline mode for some time (30 secs or one minute) and then switched back to normal and that day I had exceptional battery life (whole day = ~12h with some time checking, messaging and checking mail, with ~70% battery left) which i assume must be the actual battery life that the phone is capable of without bugs.
So long story short:
possible workaround for the Android OS bug: put phone in offline mode for ~1 minute, then back into normal mode
I would love to read if somebody tried this and gave some feedback.
HI there. My battery life on my SM-N900 is very frustrating. Previously, I used a iPhone 5s and people told me that android was much better and has excellent battery life. Right now, I don't really like android because my iPhone battery lasted 5 hours of SOT. I purchased a used note 3 n900 which is apparently less than 2 years old (original owner purchased in late 2013 or early 2014).
I currently use the Dr. Ketan L24 rom. Both this rom and the stock 5.0 TW rom have bad battery life. When I turn the screen off, the battery life is very very fine and sometimes even goes up a little by itself. I left the device for 3-4 hours and the battery actually went up 1 percent!
The minute I turn the screen on, my battery is drain. I only get 3-4 hours of screen on time. I hear some people receive 5-7 hours of SOT.
I've tried so many different methods, including wiping the cache partition from recovery, factory reset, disabling system apps (all Samsung bloatware) with titanium backup pro, disabling wakelocks, alarms and services using Amplify, Disable sync, location, and having low brightness. I also have low power mode turned on the entier time.
I also don't use mobile data so that's always turned off. I use Greenify to greenify many of my apps, including facebook, messenger, instagram, etc. I have also used apps such as GSAM battery monitor and Wakelock detector and better battery stats. None of these apps show out of the ordinary behaviour.
The only thing left for me to do is to purchase a new battery, but before i do that I would like to see if I can fix my battery life throuh software. If someone could explain why my SOT battery life is so low, it would be much appreciated!

Download Repair Battery Life, and Advanced Battery Calibrator from Play Store.
Thank you! These apps greatly fixed my battery!
I just found a pretty interesting bug that causes my G935FD phone to be constantly awake after a full charge, but will happily go into deep sleep after I restart the phone after the full charge. It reflects in the GSam Battery monitor as well as the battery life.
Maybe someone who has issue with the phone constantly awake (or very high Android System battery usage) can try this trick out. My software version is:
Baseband: APD1
Build: APDQ
My phone is rooted if it makes any difference.
Here are some examples:
After 10 mins charging and before reboot:

"lightbox_next": "Next",

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And after a quick reboot:
may b this is the cause
may be this is the cause of pathetic battery life on my phone. do u suggest a restart while still plugged in or after unplugging? Know any permanent fix for this?

I reboot them after unplugging.
I've just found this work around recently (as you can see my pathetic average doze time per charge).
Will try this for a few days to see if it helps.
Have you tried to wipe cache ? cause i've had the exact same problem over and over again and in my case it only happened with wireless charger. After I wiped cache partition it never happened again.
It is google backup bug. Turn off google backup and it should be gone.
Or restart your phone after each full charge.
Edit: it affects other phones too

Wow this is a colossal bug.
Yeah, it affects two of my phones, S6 and S7 edge!
Aloah!
I bought the S7 Edge and used it in stock version. Then I noticed that the battery loses over 10% per night. So I decided to install the Superman ROM with root and deactivated some Samsung Features. But the phone still looses over 10% per night.
I have disabled WLAN, BT and GPS. The only activated feature is the always-on-display, but this could not be the problem, because of AMOLED. I know that Samsung bloates their phones with useless things and I only recognize this battery problem (mostly) on Samsung phones. So I think the battery loss must have to do something with the Samsung features.
So my questions are these two:
1. How can I find the battery-using processes?
2. Is there a near-stock-android ROM which is fully debloated? On the S5 the stock ROM had 1,5 GB and then I installed one which has only 400 MB. So there was much Samsung trash removed.

since you are rooted start by installing either Wakelock Detector or BetterBatteryStats app and see the output of those in the morning.
also is it a used or new phone? if its used then the battery might be faulty.
also try 1 night with AOD off and see if that gets rid of the issue.
Its a brand new phone. Ok, I try these two apps.
But what is AOD?

Always On Display :: AOD
Does this really take that much battery? I mean, its mostly black and that doenst consume battery (mostly).

Id bet thats where most of your drain is coming from. Im just going by what I recall, but believe AOD accounts for 1 to 2% per hour.
I like having the AOD at night so I keep it on regardless since Im pretty much able to charge my phone at work or in the car, its not a big deal.
Ok, I deactivated the AOD but still got around 7% loss.
