Check if the device is constantly awake at the detailed battery information if you click on the graph.
If that's the case, search xda for "wakelock" and how to get rid of it.
An easier attempt is, to think if it's a certain app you installed recently or a change you made to your system.

Thank you for your response,
I'll Go ahead and download a Wakelock Detector By someone who works here at XDA, and i'll see if it finds anything; But as of now my battery died again; So i left it dead for 15 minutes, and now i'm charging it back to 100% with no interruptions

You could also install the ota update for lollipop and see if that automatically solves your issue. (new versions are being created to be better)
Another option is to flash the lollipop stock rom and try if that solves it. (but that's a bit more advance)

I suddenly got a similar issue - not as bad as yours but a drop in battery life. I turned off scanning even when wifi is off and turned on location based wifi and my battery life went back to normal. I'd just had a Google Play Services update and have had this issue with various play services updates in the past on other devices which is why that was one of the first solutions I tried.
Might be worth a shot if you haven't already tried it :good:

There's always Greenify.

Repair it or flash another ftf file.

Same thing here. Since I've had this when I purchased it new I've not had any good battery life. My old z2 had way better battery life and stamina mode works.

Was there any update to this matter, OP?
What brightness options are you using? (% and adaptive or not?)
Also, did you actually update it to Lollipop? Was there any problem with wakelock?
Best regards.

Network & Wake Lock
The last screenshot you posted clearly shows that the battery drain is because of your Mobile Network and a Wake Lock.
Network Signal:
As signal strength decreases, the device requires additional power resulting in battery drain.
The cost of 1 hour’s worth of calls is 150mA, assuming a strong signal
So, on a 2000mA battery, it takes 8% of total capacity (8% =150 / 2000)
This means the same 1 hour of calls could cost as much as 23% of battery life (23% = 450 / 2000)
Wake Lock:
WakeLocks are a Power Manager system Service feature, available to your applications to control the power state of the host device.
Wake Locks can be used to keep the CPU running, prevent the screen from dimming, prevent the screen from turning off, and prevent the keyboard backlight from turning off.

[Xperia Z3 D6603][5.0.2] battery life issues

Xperia Z3 D6603, stock ROM, non rooted, locked bootloader, Android 5.0.2, build 23.1.A.0.690.
Hello all, I have a huge problem with my Z3. I mean, battery life issues.
As you can see on the 2 pics, my device is running out of battery too quickly, and it heat up even for simple tasks!

Any help?
That's not normal.. it sucks. Will switch to LG G4 as soon as available.

how much of that was screen time using the battery?

About 3 or 4 hours max.. but I use it time to time. Wi-Fi and sometimes mobile data on cellular network.
Don't understand why the battery drain is so fast.
Stamina mode doesn't change a thing. Almost always on manual low brightness and I have to use my power bank (external battery) when I'm away.

I have the exact same issues, the phone was going very strong for the first 6 months (7-8 hrs SoT) and then it all went bad (3-4 hrs Max). I've tried MANY things and the issue seems to be **mainly** with Android OS and System (especially with mobile networks "staying active").
What kind of worked for me is:
Turn off "double tap to wake screen"
Delete any 3rd party alarm apps (clearly helped)
Turn off "Google Location History" in Google settings
Check for stuck sync
After doing all of this i got about +2hrs screen on time, but it all went bad again (even with them still off)... So I'm interested in your feedback and others' answers!

I'll try that. I assume Timely is a 3r party alarm apps?
Check out this pic.. battery discharging during the night and lost more than 20% by using it one hour (simple web browsing and stuff). I'm starting to hate this phone.
By the way, congrats for your 1st post

Yes I think we have the exact same problem, my phone discharges about 2-3% on airplane mode through the night. And as you said, my normal use means that I lose 10% to every 30 minutes of screen (under normal conditions).
Yes I mean Timely! it drained the battery on my phone and only showed up as a problem on Gsam and wakelock detector! i wouldn't have known otherwise, its disguised as Android OS or System!
Its very disappointing given that it was working very well before!

Stuck with the same problem.. and they boast about Xperia Z3 amazing battery life.. that device sucks. Switching to LG G4 as soon as available. Sony disappointed me, they failed me.
I use Timely to wake up because this app is well designed and I love the smart rise feature.
That said, Android says OS and screen process drains battery the most.

I think you should first try what I suggested for a day or two and see the results, should be an improvement, though I don't know how much...
I used timely for exactly the same thing, but as all google products these days, it drains the battery I'm really dissapointed with Google more than Sony, I have the same problems on all my lollipop devices (2 nexuses). Nothing Sony can do about it...

With flastool you can go back to KitKat if Lollipop doesn't perform good for you.
I have good experience with the .77 Version and still have a backup of it in twrp.
You have a very weak signal (the red color) which is draining battery.
Android OS is the Kernel.
Use better battery stats which is free here from xda.
Also check app permissions of your installed apps.
And a calibration of the battery may help.
With full auto brightness and mixed 3G/wifi browsing and listening to music via Bluetooth or headset I have 6h Display on in 2 or 3days on Lollipop.
But prerooted / debloated / tweaked Rom .690 with good signal.

I know the signal is bad and is a cause I'm my case. I was living in Germany for a few months and got around 7h over 2 days, it halved when I moved back to jordan. However it's still getting worse, noticeably since I turned off and uninstalled many things (it got better for 2 days *6hr and then went back to bad *3-4hr). But still the point is why buy a smartphone if you have to turn off everything just to get it through the day. The problem is that you get the feeling that no matter what you do with the phone it still drains (which looks like a system or app issue because it does even when I'm only using Wi-Fi or even 3/4g on full signal)...

Well there is no magic button to improve the battery life.

Yes there is, Airplane Mode.

Cell Standby Battery Drain?

Cell standby is continuously one of my top two battery drain items. I did a search and found a recommendation of booting into recovery, wiping cache, rebooting, and ensuring that advanced calling was turned on. I went through those steps and while it may have helped a little, it still seems to be using much more battery than it should be. Anyone else battling this on a Verizon version? If so, any other items I can try to fix the problem? Thanks in advance!

I have this on my s6, but not on the note 5.

I just can't seem to find what is causing it.

I get it too but it doesn't seem to drain my battery much. I'm still getting 6 hours of SOT. I haven't used my phone all that much the last few days but I'm at four days without a charge and 29% left. I tried clearing cache three times but cell standby remains on top. It would be nice to get rid of but it's not killing me.

Thanks for the response. I do already have advanced calling turned on. This may vary from carrier to carrier. I am on Verizon.

I have this issue when I have WiFi on, with WiFi off just have no issue

If you are like me then Cellular is still going even when on WIFI. If you notice, the 3g/4g icon is activated and WHITE when using data. Otherwise it is grey. From what I understand when on WIFI this should always be grey. I should also mention I do not have Advanced calling turned on.

Keep in mind results vary depending on where you use the phone. Do you have a weak cell signal? When the signal is weaker, the phone compensates by using more power to boost it as much as possible. I haven't noticed the problem but I'm usually full or one bar from full signal at my home.

Mine drains more than 2% during standby, which is definitely not normal

Fix for cell standby bug is to go to Settings > Wi-Fi > more > advanced then make it look like this.
This is for the people that are having issues with the battery draining while on wifi only.
Setup like image below and it should fix your issues.

Battery drain will always vary my mileage, what firmware version are you on, what apps you have open , are you on LTE, 3G, wifi or no wifi and how many apps you have going, running in the backgroud. etc etc etc.

my is exactly like that, cell standby is still crazy high

No idea why this worked but switching data from global to LTE /CDMA only seems to have fixed my cell standby draining while on WiFi.

I bought my Note 5 on VZW yesterday, after coming from the note 5 on AT&T. My issue seems to be unusual high Android OS draining my battery. Maybe new phones just need a day or two to settle? I'm about to clear cache for apps by rebooting into recovery. I have done the following:
-Disable VZW/Samsung Bloat (Package Disabler Pro)
-Disable S Finder (Package Disabler Pro)
-Turn off motion Gestures
-Turn off S voice
-Turn off or decrease vibrations
-Turn off Google Location History
-Turn off Android Device manager
-Disable Unnecessary Sync Service
-Turn off S pen Alerts, pen detection, and S pen sound and vibration (will still work exactly the same)
-Turn off 'Always allow scanning' under advanced wifi settings (Allows apps to serach for Wifi even when wifi is off)

I have seen location history posted as a possible battery drain when not using phone. Check to see it's status. Turn off and try.

This helped. Just because Location isn't used, does not mean Location History is disabled. Thanks!

Help finding/fixing idle battery drain

Hi my wife bought a Note 5 two days ago (9/30). She did all setup, app restoring, etc that evening and fully charged the phone overnight. However her phone is experiencing idle drain that I need some help fixing.
Some other info: battery saver modes are off, wifi is always on (but only connected at home), bluetooth is always off.
10/1: Arrived at work with 100% battery
A little over 4 hours later, with light use, the phone was at 51% with less that 45 mins SOT

With facebook as the biggest offender I suggested she turn off the setting of pre-loading pics and videos.
When she got home she charged phone to 100%. I also changed mobile network to CDMA/LTE. Here's how the battery looked with light use before going to bed:
10/2 - Left the phone unplugged over night to see what would happen, it lost 12% sitting on the nightstand for 8 hours.
Will report back later this afternoon to see how the day is progressing.

First step for me in reducing battery drain was to disable the Facebook app. It is a battery hog and was always at the top of my list. Instead, use a browser and create a shortcut to facebook.com or install Metal from the Play Store which is a web wrapper for Facebook and so much lighter. Sometimes I still get strange battery drain from Android system (up to 35% sometimes!). But this usually gets resolved just by opening up recent apps and closing all.

Hmm, I don't have problems with Facebook app on my droid turbo

Some people want notifications.

Regardless, Facebook doesn't seem to be showing up at the top afte the setting change. I'm interested to see what she has this afternoon. Will have some updates screen shots later on. I also asked her to charge ~3pm then drive home with nav on to see what the battery looks like under heavy usage.
I need to dig into Android System to see what's going on there, any ideas? Will GSAM pro give more insight here?

Not looking good, 22% used in 2.5 hours with 20min SOT

Where is the setting for turning off preload pics and videos in Facebook? I dont see it in the facebook app settings.

I lied, facebook setting is "play videos automatically", I have to assume turning this off will save data/battery. Also Instagram has "use less data" setting. I thought I read that this stops pre-loading of videos/images, but I might have imagined that?
Anyway, for facebook setting hit the menu button next to the notifications icon then scroll to "App Settings" near the bottom of the screen.

After most of a work day and light use she's down to 58%. Looks like facebook is back up there, odd because it's not a problem on my phone.
Does anyone know how to troubleshoot why Android System is using so much battery?

I have a note 4 and I'm having similar issue ls

Hi I'm facing kind of same problem but other device HTC one m7 and rom is aicp I don't know what is draining battery in idle time but almost 10 to 20 % is gone in idle and the fun thing is I use airplane mod all the time

You guys have to also take in consideration the Lollipop total connection time bug. Apps open up a connection and it won't close it when it's done... For example my first charge cycle I signed into instagram and it used 40% of my battery without me ever open again. The total connection time of most apps ends up being hours when it shouldn't be. That won't be fixed untill Marshmallow comes to the Note 5. Google is aware and has fixed it. It's on multiple Lollipop devices.

Yea I've used that for a while. When I force stop an app I tend to not see it encounter that bug
Verizon Wireless Technician using Tapatalk on Note 5

If the device is rooted then you can try Greenify to hibernate the apps which are consuming the battery life.Try other simple solutions like disabling the Wifi and other tools when not using them.Sometimes Play services may cause the issue so try to fix them.There are some guides which may help you http://fixdroidbattery.net/fix-fast-battery-drain-problem-on-samsung-galaxy-note-5/
http://recomhub.com/blog/how-to-fix-samsung-galaxy-note-5-fast-battery-drain-problem/
Hope these guides will help you

The problem is ...because of the device used to be root although we flash original stock firmware it is still drain when device idle ...you can take a look in Android OS and see stay awake period ...one way is flash custom room that said deep sleep fix . Hope this comment could deal your problem

Question Where are the battery troubles in the LTE models coming from

There seems to be some sort of consensus that the LTE versions of the watch have more battery trouble
Has anyone actually given it some thought as to why?
When LTE is off it should not make a difference, but it does seem to exist.
Is the emergency service always connected, is there a bug where the modem drains power even when it should be off?
Curious to hear what you think

I have discovered my mistake was thinking that I needed to have the LTE button in the quick menu lit up blue to work away from the watch, my battery life has improved since I discovered it doesn't need to be lit up blue as that is permanently "on", by having the button grey it's on "auto"

I think that's the same button I called LTE/mobile network, it's the up/down arrows design button, sorry for the wrong description!

I got mine the other day replacing my 1st gen galaxy watch. I set it up in the same way as my old watch and was amazed to see the battery drop 10% in one hour, since then I have made one change... I disabled the option for the screen to come on via gesture, settling for a tap if the screen... I took it off charge this morning at 5:30am and it is now 21:21BST... It has 58% remaining... a significant improvement over day 1

I have the same problem with LTE. Whenever I use "auto" for LTE settings, the watch would keep trying to find signal and that would drain the battery. Which is insane, especially because: 1) the phone is always nearby, bluetooth connected 2) i haven't set up any carrier yet!

I have the network connection on. For me, i have a good 2 days of battery life. Compared to my previous WearOS watches, it's excellent...

Did some testing and disabled everything (HR, Stress, Exercise detection, notifications, LTE/Mobile data, Wifi, NFC) all that was left on was the BT connection and I was still getting about 8% per Hour drain (12 hr 30 min life). Disabled BT and enabled Wifi for connection and drain now at 3.6% /H. (Stats as per Battery and Charge Monitor for Wear OS). So it doesnt appear to be a drain from any of the health monitoring or notifications etc, but possibly from the OS, which hopefully Google/Samsung will resolve/improve with updates.

There was a Health Services update yesterday and since then, my watch battery lasts WAY better. at 17hrs 33min i still have 64% left and i had re-enabled everything again as it should be. Continuous monitoring, sleep with SPO2, location, LTE, etc.
