SnooZy Charger for Android
Power connection can turn on display when unwanted. SnooZy avoids intrusive screenlight during nighttime-charging and saves power consumption.
SnooZy can be very useful with wireless, solar or dynamo chargers, where power connection is hectic! It can also be used for auto-lock or for connection history. Check Settings to make the app fit your needs…
Running in the background as a lightweight service, it saves the connection/disconnection event into a power connection history. User can also receive a notification with/out sound or vibration. This app does NOT manage any other phone functionalities, such as WiFi, Bluetooth, GPS, etc. There are other apps for that…
It was initially developed as a fix for battery drain issues on Samsung Galaxy Nexus: some devices randomly detect a power connection without any charger being actually connected to the phone. This would drain the battery because of the screen turning on to display the "Charging" message, multiple times per hour till screen timeout.
SnooZy is an open source project, available on GitHub https://github.com/mudar/SnooZy. Source code is released under the GPLv3 license from the Free Software Foundation.
Many thanks to G&A!
Some users have asked about uninstalling the app: first you'll need to deactivate the app as a Device Manager. There's a shortcut for that in SnooZy's settings (last item). If that fails, you need to go to Android settings / Security / Device Administrators and deactivate SnooZy. Once deactivated, you can uninstall as usual. Please note that this is an Android feature, not SnooZy's!
Wow, thanks so much for this little app! I didn't expect to find a solution to the annoying default Android screen behavior when plugging and unplugging USB power. It was getting really annoying shutting off the screen all the time. Your app saved a piece of my sanity.
So tired of having to turn the screen back off when I plug in my phone (LG G3). Been looking for a root free solution for awhile. Finally found it. I'm running Marshmallow, so hopefully it still works after the Nougat update. Keep up the great work!
An update to Android that requires a pin when a device administrator turns off the screen makes it too inconvenient to use if you use smartlock or a fingerprint sensor. Other developers have built in a way to bypass this problem if you have root, but not this developer.
Was tired of my phone coming on in the middle of the night, just because the usb charger had a blip. This app turns the screen right back off. Thanks.
Works OK. I wanted something that would make the screen NOT turn on/off when connecting or disconnecting with power. I don't care if the screen is locked at the time or what the power source is. I simply want the screen to stay the way it was when I plugged/unplugged it. This doesn't work that way. It flickers the screen and then turns it off. Not helpful. It also forces a hard lock on the phone and a fingerprint scan no longer will unlock it. Says "Device Administrator has locked this device". And I need to enter the pattern code instead of a fingerprint. Uninstalled.
When my phone is charging wirelessly at night, it often loses the connection before reconnecting again. Every time it does this, the screen comes on, waking me up. This app turns it off again. Unfortunately, it doesn't prevent the screen coming on in the first place but turns it off after 2 seconds. Which is too late.
Fantastic. I thought it is the stupidest thing to turn on the screen when you plug in to charge. You're just going to press all the buttons on the screen. Hopefully this can do it for low battery as well eventually. Battery low? Let's turn on the screen to drain it faster! Android!?
The only thing keeping me sane with stock Android. I dumped my Cyanogen Mod Galaxy S3 for a 6P and immediately was infuriated by the screen coming on when I plugged/unplugged it. Grabbing it one handed often lead to icons moving around and whatnot as I tried to not touch the screen and not drop my toddler. I found SnooZy and it was a miracle. My screen now stays off and there is no more havoc every time I try to grab my phone off the charger real quick.
With my charging port broken, my phone thinks I keep plugging in and our my charger, keeping my screen alive at all times. This app only makes it blink and it stays off. I'll give them a 5.
You get up, unplug your phone and the screen pops on before you pocket it. A needless function for me taking my phone from home to the car, ect... awesome solution to a nuisance problem.
How do you make this work :-(
PLEASE HELP ME!!! I downloaded this app so that my phone could stay off when I plug it in. It did work. The problem was the setting was set to the screen shutting down when it's plugged in or unplugged and I didn't realise. Because of that, whenever I want to boot my phone whether plugged or unplugged from the charger, the screen automatically goes off 2 seconds later before I can open anything. I try to change the setting and uninstall the app but too late! The screen shuts down 2 seconds later when my phone boots after powering it on!! PLEASE HELP ME!!! MY PHONE IS UNUSABLE NOW!!!
This does everything I was hoping for. It stops the screen from turning on when charging, allowing me to charge the phone with a dynamo hub.
My screen still comes on any time the charger is connected or disconnected. Most annoying thing about Android and unfortunately this doesn't do anything to help.
I have to use my moms charger Cuz I broke my charger in ONE week so yea I'm praying plzzzz.let it work
I've read that this app is kind of a "hack", since the screen does blink on momentarily when attaching or detaching the charging cable. Personally, I consider that kind of a "feature" that lets me know it's plugged in OK.
Only problem it that I cannot set lock delay to none. So every time after charging I must unlock phone with code.
I thought this appw as supposed to not let my dosplay wake but it just turns it off after 2 seconds... nope.
Did not work well for S7
Neat looking app that works perfectly.
Was tired of my phone coming on in the middle of the night, just because the usb charger had a blip. This app turns the screen right back off. Thanks.
Battery charges much quicker and lasts noticeably longer. Solves loose cable and battery charge issues. Stops screen coming on when charging.
Works a treat, though it would be nice if it could also turn the screen back on when removed from charger.
dont work do not download this app please
Amazing. I just installed this app and use it in conjunction with No Lock so I don't have to deal with a lock screen except on startup -- and I am impressed. Why I would want my phone to come on when I put it down on the charger is a mystery to me, but that seems to be just one of those Android annoyances that the developers somehow don't see as worth addressing. I looked and looked and I could not find a solution, but so far, within moments of installing, this appears to be it!
I want to edit my review because after removing some other apps, it may not have been the cause of my battery draining fast. I will have to try using SnooZy after I removed the other apps. Other than that, it is a great app that does what it says.
This app is perfect for what I was looking for. With Android, when you plug & unplug your device into the charger, the screen lights up and there's no setting to disable this. Now there's a work around using SnooZy Charger, just install and select the settings specific to your device and you have a fix for this particular case.
I wanted this to stop the screen turning on when connected and disconnected to the charger. This worked however one other feature was equally as irritating. Screen lock on disconnect and reconnect. If I have unlocked my phone and then disconnect from the charger, because of this app, it will lock which forces me to unlock it again. After uninstall this 'feature' is not removed but maintains the setting chosen in the app. The app doesnt allow it to be turned off.
It doesn't work at all
My phone just stopped charging and I really really need my phone for school and it's saying connect to charger. MY CHARGER STOPPED WORKING
but it lets screen turn on for a fraction of a second.
Fixed the problem of screen waking when wireless charging connects/disconnects on LG G3
Let me delete it
Does the job as described, full of nice options for further customization. Thanks for your nice work :) Suggestion : do you think you could add the same options for turning the screen *on* after a power event ? My Nexus 5 unfortunately doesn't power on when lifting it up from my wireless charging station. Thanks again !
Finally a solution to stop my screen activating every time I plug in/pull out the charger. Works great on my Sony Xperia Z3+ with Android 5.0.1. One minor issue, stopping it from getting 5 stars, is that the screen still activates for half a second before turning off, but at least I don't have to press the button now, and the screen will be locked by itself by the time I put it in my pocket.
thank you, it does exactly what it says
Doesn't do anything... Screen still turns on and stays on... Cant even deactivate this virus!!!
How do you make this work :-(
Turbo charge

So, the app does kinda work... When you plug into power and the screen is locked, it still unlocks first and then the app locks it back. This is not the functionality I was looking for... I wanted to turn off the effects of plugging in the charger altogether. This would be fine for me if the app could consider screen on/off rather than just locked/unlocked, as I don't like putting a password on my phone. This means the app always turns my screen off when plugged in even if it's on. Looks like I'm rooting.
