Battery Life Suddenly Dropped

Hey guys,
About a week ago I started rapidly losing battery life.
I've done a bunch of research and installed task killers, OS monitors, Spare Parts, etc. I've uninstalled apps that had wake_lock and done a Reset to Factory Defaults,changed the brightness, as well as performed a recalibration for the battery (one cycle). I also turned the phone to Airplane mode since I moved offices and thought maybe that was a problem.
I am not sure why this is the problem, but I have notices through spare parts that my phone does not go to sleep. The time it gives for Time without Sleeping (under "other Usage->Last Unplugged) is typically about the same time as I have had it off the charger. The phone will not last a full day anymore (Actually I'm lucky if it's still on when I get home from work). The only program that I can think of is the new maps application.
Here are my questions:
1) Is there a good way to find out if there is a specific program that is not allowing sleep (w/o uninstalling everything and adding them back one by one)?
2) How do I fix this problem? Would a hard reset work?
3) Generaloes anyone have any ideas on how to fix this? Why wont my phone go to sleep?
4) Could this have anything to do with the new maps/navigation update that Google sent out OTA last week?
Right now it has not slept for over 5 hours, but I been pressing the power button (not turning it off) when I put it down.
I ca provide a list of programs if that helps, probably some statistics too
Thanks!

In Spare Parts under Battery usage, there is a "Partial wake usage" option. Did you check that to see what is keeping it awake?

Since Last Unplugged:
Android System: 6m 16s (blue bar)
Dialer: 1m 40s (blue bar)
Facebook: 56s
Google: 44s
Media 28s
Google Voice: 20s
Calendar: 20s
Messaging 4s
None of that seems to make sense when you look at:
Other Usage: Time Spent Without Sleeping: 6h 36m 1s..
Maybe I am mis-reading it?
Thanks!

Is there a background data killer for android?

hi all, as you probably know, cell standby (data background while phone is standby) takes ALOTTTT of battery so i want to know if there is an app to auto kill data network when i power off the phone (to avoid cell standby) and power on again auto when power on the phone from standby

juicedefender

You mean Juicedefender and such (if I remember correctly, there is at least 1 more app that does the same thing), and IMO - it completely defeats the whole purpose of modern mobile OS. If I didn't want to be connected to the network wherever I go, I wouldn't be buying a smartphone.
The battery lasts a day easily, with or without data.

if you want to completely disable data, the app youre looking for IS juicedefender - the free version disables data completely and re-enables it every 15 minutes to get any notifications.
I would also suggest trying:

which switches 3g to edge (and uses less battery) after a specified amount of time in standby

Battery savings guide

Hello, i use Dalingrin's kernel (6/30) and CM7 nightlies (121 currently).
Sometimes deep sleep is nice for my battery, sometimes it doesn't save energy.
It's life but i need a few days between battery charging.
so i decided to add a few workarounds, here they are:
1. Airplane mode everytime + wifi on/off when i need it. Only ten seconds to activate/deactivate with CM7 status bar.
2. Battery widget monitor: it enables history of battery consuming. Very good to act that deep sleep is effective or not.
3. uninstall applications which sychronize when nook should be sleeping: K9, DSPmanager, hotapps, appbrainz.
3. Advanced task killer pro: Crazy mode when screen is off. Very nice for last applications.
Of course, you are welcome to comment those tricks and to add some

I guess it depends on use, but I'm on day 3 on a charge, running at 47%. I just have the screen at 15% most of the time, and I don't disable sync. I mostly do reader, email, internet, so that might be part of my success.

1 is probably not a good idea, since sometimes Airplane mode sticks.
2 has nothing to do with saving battery, but okay..
3a does nothing if there is no network connection (assuming sanely written programs)
3b is stupid and shouldn't ever be used.
You want to save battery? Turn off wifi when the screen goes off. You can do this automatically with Setting Profile Lite or Tasker, probably some others. I've found that the wifi sleep setting doesn't do anything for me, I can continue to ping the NC for 10+ minutes after the screen goes off so clearly the wifi is still up.
And watch Spare Parts partial wake locks and see if you have any misbehaving apps. I find that Maps with Latitude enabled misbehaves without a network connection and constantly is trying to update or something, so I cleared data on Maps to get out of Latitude on that device. CPUSpy will also show you how much deep sleep is ongoing.
The NC is going to use at least 10%/hr at low backlight doing simple tasks, I've seen it use up to 25% overclocked playing games.
While asleep it uses about 1% every 3-4 hours. Could probably do even better if you don't have a boatload of apps and widgets like I do.

Grab "Where's my Droid's Power" or whatever the application is called, and see where all the power is going.

He said the battery widget is to see if it is asleep, and see what the consumption is like.

Hello,
You are right about battery logging.
i have to test the two applications you mention both:
1. "And watch Spare Parts partial wake locks and see if you have any misbehaving app"
2. "Where's my droid power".

Ways to improve battery life?

Sorry for the long list of screenshots above, and also for creating a new topic, but didn't want to spam the normal board for battery discussion.
Anyway, I have the N920I model of the Note 5, using it on Telkomsel in Indonesia, and getting average 3+ hours SOT on this device, which I think could stand to be much better, given I got around the same figure on the Moto X 2014, which has significantly worse battery life according to most counts.
Here's my settings:
Screen brightness 60%, auto
Sync on
NFC off
Location high accuracy
Bluetooth on from 8 to 3.30, then off for the rest of the day
Connected to an Asus ZenWatch 2
Wi-Fi on from 4 to night, from plug out in morning to 8
Here's the list of apps I disabled:
And here's how my usage goes:
* Plug in when I wake up, then out at 7-ish.
* Get to school and let My Places switch to "Work" mode, where it changes the Bluetooth, Wi-Fi and power saving settings and turn off data before starting the first class.
* Turn it on between classes to check for new messages.
* Leave at 3-ish, and get home, letting My Places change the settings back to normal. At this point, the phone is usually at 70% with an hour of screen on time to report.
* Use it periodically throughout the rest of the day, switching between WhatsApp, Snapchat, Netflix, Chrome and YouTube.
* Plug in at 8 or 9, then plug out before I go to bed, topping up what's left in the morning.
It's a fairly light usage pattern, which reinforces the point that this phone should get more than just 3 hours. Any specific app you're seeing here that might be putting its toll on battery life, or a specific setting that you can advise enabling or disabling?

Just try counting how many threads there are about battery life in this section. A lot! I, being one of the victims of horrendous drains, have tried everything. If you keep the device relatively clean(software) and it still drains then there is only one thing you can do. Wait for the marshmallow. I'm sorry but that's what it means owning a samsung device.

try gsam battery monitor. It may give insight into what is going on....

Already did! But Android OS is always the top consumer.

thanks!

As Octa_core mentioned, there are quite a few threads about battery life already. They might be of benefit if you haven't already looked through them.
Here are a few things you might try, if you haven't already.
- Turn off location high accuracy, or only turn on location when you need it (if you can)
- Turn off location history
- Turn off Always Allow Scanning in Wifi advanced settings
- Turn off S-Pen settings (alerts, sound, vibration, detection)
- If using Google Fit, disable activity detection in settings (this definitely helped my idle drain)
- Turn off anything you don't need to sync on your Google Account
- Disable enhanced LTE services
- Turn off Motions and Gestures you don't use
- Set touch key light duration to Always Off (under Display)
- Turn off Smart Stay
- Set Screen Mode to Basic
- Use a darker theme
- Try disabling some apps, especially S-Finder (may require Package Disable Pro to disable some apps)
- What does your signal look like in GSam? Some drain may be due to poor signal.
If none of that helps, then uninstall or disable (probably will need Package Disable Pro to disable) all apps you installed, and I also recommend that you disable S-Finder. Turn off all radios (location, NFC, bluetooth, wifi, even data) other than cell. Reboot after those changes. Monitor and see how idle battery drain is. After I did this, my idle drain was around 0.4% per hour. Then you can gradually enable radios/apps, only 2-3 at a time, reboot, and see how it impacts idle drain. Continue until you find app/radio that increase idle drain.

ssp_sensor_hub_wake_lock - need to catch this battery thief

Hello there . Using Better Battery Stats I found out about this process which takes my phone out of Deep Sleep for about 5 minutes every hour. Totally annoying.
My phone is seriously trimmed down. I'm very strict when it comes to what is running. Data connection is almost permanently disabled, no weather widgets anywhere (that I'm aware of), no sensors active, extremely few processes in background, and even those that are have been thoroughly vetted. I'm using Disable Service / Greenify & Autostart to seriously trim down on whatever is running.
I did notice that when the phone is in Airplane mode, ssp_sensor_hub_wake_lock is keeping my phone alive "only" about 1 minute / hour. That is still too much, since I do NOT have any sensors that should be active at that time.
CONCLUSION AND THE ACTUAL QUESTION:
How can I investigate WHAT PROCESS starts ssp_sensor_hub_wake_lock OR ALTERNATIVELY get any logs / debug that could lead me to the culprit.
Thank you in advance!
