Does anyone running MIUI 1.6.3 or 1.6.10 experiencing large battery usage listed as "sensor usage" in the "android system" category?
Here is how to check:
1. "Settings->Battery Settings->", enable usage monitoring
2. Wait for few minutes
3. Make a phone call (check voicemail or something)
4. Now check battery stats. In my case, I see "Android system" at the top. When I drill down into it, "Sensor usage" uAH is more than 100 (after about a one minute phone call).
I am guessing that when I make a phone call, the proximity sensor is activated and ends up using lots of power.
After about an hour or so of phone calles the uAh for the "sensor usage" is more than 5000.

Use the Battery Monitor Widget (set to 1 minute polling intervals) to track the drain of your phone. This will give you a lot better indication of realtime battery drain. It's possible the "Battery Settings" screen is giving you some false info. I haven't found that screen to be particularly accurate at times.

Thanks, looks like there is no real battery drain after all. The stats are not reported correctly.

Cool, glad to help.
HD2 MIUI SD.
Same problem. After work of proximity sensor current not return to normal low state and stand at level 50-70mA. Only turning off sensor(dialer settings) and reboot help me here.
I have my Tf700 rooted but locked. I have been trying to just put the tablet to sleep rather than shut off (long boot times). With the sreen off and using Auto Airplane Mode by Don, my tablet is draining by 15 percent overnight (9 hrs).:crying: I'm using Battery Stats Pro. It shows that 'Cell Standby' is using >90% battery. I'm at work right now and my tablet is at home charging so am unable to post a screenshot

Where can I find this auto airplane mode app? Will it work on stock unrooted also? I have noticed "Maps" automatically gets turned on and used by WiFi after the jb update. Anyone know how to fix this? WiFi just stays on and drains the battery.

Play store: Auto Airplane Mode by Don
There's Battery Widget Reborn that will do this also. But then I'm using JuiceDefender Plus on my 3 devices. Works pretty well on my TF700, there's a "night mode"... My tab hardly loose any juice over night. Maybe try one of those...

I have Juice defender Ultimate installed. The problem is that I want the tablet to deep sleep every time I put it in standby. I am still losing 90% of battery to 'cell standby" even with juice defender.
Anyone have an idea about the maps issue?

"90%" Does not mean it drains 90% of your battery.
It means 90% of the current battery drainage belongs to that process. So 90% of the 15% battery drain comes from Cell Standby, the remaining 10% are other processes (usually Screen.). So something else is draining your processes.
Cell Standby is the same as Idle Processes on Windows: Nothing.
It should use about 1-3% per night even without 3rd party airplane mode. So, based on not using that, which of these do you have enabled:
WiFi (Especially the "Keep during sleep" setting. Even with WiFi toggled off, this keeps running undetected. Same goes for USB Ethernet.))"
GPS
Power saving, Balanced or Performance mode?
Power Saving in settings
Auto brightness
Location services (settings --> location services), any of the settings in this menu.
Ever used a USB Ethernet adapter?
Using any overlay apps? (handwriting, graphic effects, alarm etc?)
Does the tablet's location get very cold overnight? Lithium-Ion batteries hate the cold, drains them 10 times as fast.

Idle is called "Tablet idle" on my TF700. "Cell Standby" sounds like the connection to a mobile network, which should not even run on a wifi-only device.

This was my first idea as well -- your 700 doesn't even have a cell connection, so this is a strange entry. Try using BetterBatteryStats or something alike, because the standard Android report of battery consumption is notoriously vague, and most of the times downright incorrect.
This harkens back to my SGS2 tweaking days in which loads of users were clamoring for tweaks to get the Android System consumption down from 99% -- "it is killing my battery" -- even when they had less than 2% overall consumption overnight. LOLOLOL!
These are high-powered devices, people -- if you'd want two weeks of standby time, you should have hunted down an old Nokia Communicator.
I still find a 15% drop in 9h of stand by time a bit high. Mine is a lot less than that...

Hm. Regarding the USB Ethernet adapter: Did you ever set the option "Keep during sleep"?
Reason I ask is because the moment I turned this on, it started draining my tablet+dock in a day, even without the adapter. Turned keep during sleep off and it went back to 1% a day. Never showed up in any battery monitor.
jcp2, do you have the TF700KL model version??
I will plug the usb ethernet adapter back in when I get home and see if the option "keep during sleep" is checked.(I only used the usb adapter twice.) I have the TF700T model.
Update.... I docked the tablet and plugged in the usb ethernet adapter. "keep ethernet awake during sleep" was checked. I unchecked it. I will let it sleep overnight and check the battery usage in the morning.

Fingers crossed, then.
Great news everyone! After following ShadowLea's advice about the unticking the USB Ethernet option for "Keep during sleep" (Which is only visible if you have the USB Ethernet adapter plugged in BTW) I am very happy to report that my tablet lost only 2-3% over a 9 hour period overnight. :victory: Thank you very much everyone, especially ShadowLea for the heads up! :highfive: :good:
Glad it's solved

Same problem here, except even more extreme. My battery dropped from ~90% Tab + ~30% Dock to 24% Tab and a dead dock overnight. The culprit for me also appears to be cell standby at 90% of usage.
I do not have the KL model and so there is no cell radio, and have never used a USB to Ethernet adapter (didn't know that I could, I might try it out now that I know).
Keep WiFi on set to never
GPS Off
Power Mode in Balanced
Power Saver enabled after 30%
Location & Google Search the only location service enabled
No overlay apps.
Kept inside at a reasonable temperature.
I'll try turning off the Location & Google Search, but anyone have other ideas?
EDIT: See screenshot http://db.tt/ph1d0FVT
I keep Airplane mode checked
GPS off
location settings all unchecked
under ASUS customized settings: check "mobile dock battery saving mode" and also check " disconnect network during sleep" , Uncheck "enable smart backlightlighter adjustment"
These settings cured my battery drain problem. Good Luck!
There is a known bug with Location Services that causes battery drain, as it keeps checking for a signal, even with WiFi and the app off. Turn it off
I recently noticed after the latest update excessive battery drain as seen in screenshots posted below. I have tried a factory reset and then unlocked bootloader to root and added greenify to try help save my battery. Does anyone have any tips on what else to try?
Have you tried to figure out what the Miscellaneous drain is? At least on my tablet I don't have that category in battery usage.

Miscellaneous is android figuring out the rest of the battery stats, it's normal for new devices.

If by "new" you mean recently flashed/factory restored, then I'm not sure what to say. Even after flashing a recovery image I've never noticed that category. The only reason why I asked was because I assumed that was what you were referencing as being excessive.
If you were referencing the 24+ hour battery life graph shown in your screenshots, then that seems about right. Unfortunately the tablet has never been known to have stellar battery life unless it's on battery saver 24/7.

Seems about right?! He had 7min 2sec screen on time. If thats "about right" to you... you need to RMA your tablet.
Clearly whatever "Miscellaneous" is, is his issue.

Ok, so I noticed the very same thing when I got my Shield, I haven't rooted (I had on KitKat to restore some backups, then didn't do it again in Lollipop yet). I contacted Nvidia's service via livechat and got this answer. It did some considerable difference, although I still think it's draining a little too fast, but my old tablet had a pretty strong battery so I was just spoiled by it it seems >.<
So here it goes:
Nvidia Shield Callibration: (this takes a while)
You will have to calibrate the battery for just one time and observe the device battery backup for 2-3days to see the changes.
1: Drain your Shield tablet battery by using it normally until it turns off by itself.
2: Power-on your Shield tablet, if it wakes up and if you see some power left, follow step 1.
3: If Shield tablet is now drained to the point it can't wake up, set the device to charge for 7-8 hours.
The device should remain off when you set it for charging here.
4: Unplug the charger after 7-8hours, power on and wait for the battery charge to drop down to 90-95%.
5: Once the device battery drops down to 90-95%, plug in the charger and charge for one complete hour.
6: Unplug the charger once the device is fully charged.
7: Go to Shield settings > Shield power control > Apps> select optimize all option.
8: Go to Shield settings > Shield power control > system>
• Set the brightness to auto.
• Change the sleep option to 2 minutes of inactivity instead of default 10 minutes inactivity.
• Change the processor mode to either optimized or Battery savings.
• Check the WiFi optimization on.
Observe the device performance and report to us if you are still facing issue with the battery backup..
And then they gave me some tips for better battery life in general, I follow them (mostly) and my battery seems to hold on decently:
1: Always use the Shield tablet charger and not the computer USB ports or any other charger as the power specifications vary from the device to device.
2: In case if the charger is missing, use the back port of the desktop computer to charge the device instead of front port.
3: Always remember to exit the application instead of tapping the home button which will continue to run the application in the background.
4: Restart your Shield tablet at least once in a week. This will refresh the device making it work faster and efficient.
5: Connect the charger only when the battery comes down to 15% and unplug the charger only when it reaches 90% or above. This will reduce the number of charge cycles which will make battery last longer.
6: Use a third party app manager like Clean Master and free the memory at-least once a day to keep the device running faster.
To notice if the battery is fully/optimally charged when the device is off, look for the led indicator next to the charging port. It should be green, indicating it is fully/optimally charged
I recently updated my Nexus 5 to Android 6.0 and now when I go to the dialer and enter *#*#4636#*#* the testing menu is now missing the "Battery Information" menu. It had phone uptime, battery health, battery temperature and a few other things.
What happened to it? I still get the other three options but not the one I want. Is it just gone? Maybe moved to a different place?
I just noticed this! I wanted to check what the health of my battery currently is, but now there is no way to check this anymore? Seems like the exact opposite of what Google wanted to achieve with Marshmallow, giving the user more insight into battery information.
Hello MOAR users,
I'm not sure this is a MOAR issue. Something changed and I don't know what. For some reason when I plug in w Samsung USB cable & multiple different Samsung Adaptive Fast Chargers that previously would indicate "charging", now they do not. Inductive Qi charging seems to be working, although I'm not sure it is at the faster rater. On occasion it too has not worked but restarting the phone re-enabled it. Odd. "Fast Cable Charging" slide switch is "on" within the settings\battery area of the phone. I'm using Galaxy Charging Current app, to watch charge rate. In the MOAR General tab, Adaptive Fast Charging and Wireless Fast Charging buttons are red, indicating enabled. Anyone else experience this issue? Thanks in advance.
Also, how do you get what looks like a down arrow [on the extended power menu screenshot of the MOAR main XDA page] to further expand the options in the "Extended Power Menu"? I can enable a fixed number of them after which their respective icons are off screen and you can't scroll down to tap them. Touching the screen exits out of the menu in its entirety.
see this post too which describes pretty closely my issue:
