[APP][GPLv3] SnooZy Charger - Battery saver for Galaxy Nexus ghost charging - Samsung Galaxy Nexus

Hi everyone,
SnooZy Charger is an open-souce (GPLv3) Android app I developed initially for a friend whose Galaxy Nexus phone had battery issues due to the Gnex ghost connections!
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.
The app runs as a background service, listening to power (dis)connections. The event is logged into a power connection history (can be useful!) and the screen is turned off to save battery consumption by the display.
The APK and source code are available on GitHub. Scan the QR Code to download for free on the Playstore.

Feedback, comments and suggestions are most welcome! Please take into consideration that this is still a beta version...
thanks,

I never knew that my phone had the ghost charging problem this bad. In 2 hours I had 1247 events, thats way too much. I didnt even touch the phone and it dropped 30% battery. The app is a bit aggresive I know its still in beta but this is what I saw. It turns off my acreen real fast when I'm in the lockscreen, sometimes it takes me up to 3 times to unlock my phone because the phone's screen turns off fast.
Btw: The app is really sinple to use and I like the holo style it is very clean looking, thanks for your time and effort, hopefully you are able to find a solution for this problem.

Thanks for your comments
I never imagined that events could occur so often! I'll look into a cleaner way to do the screen lock, to be able to handle that frequency.
Technically speaking, the app does not handle screen on/off:
App listens to power connection/disconnection
OS turns the screen ON on power connection
App, afterwards, locks the phone. This is based on settings (is phone locked? Is it power loss?)
Locking the phone, turns the screen off.
The more efficient way would be to tell the OS not to turn the screen ON on power connection/disconnection (if the screen is turned OFF). However, I don't have the impression the Android SDK allows such functionalities!
It will probably be simpler to add Screen lock aggressivity (0, 2 o5 seconds) in settings, which would define the delay between consecutive screen locks.
Will see what I can do!

Cyanogenmod has a feature to not wake the screen on power connects/disconnects as well. Good idea with the app for everyone else!

I had this issue and it was caused from my phone getting moisture, not exactly wet but having it in my pocket from sweating or being in the rain. I dried it out with a blow dryer and haven't had this issue since. Also I used alcohol and cleaned the battery port from corrosion and that seemed to really do the trick.
Great app though in case I am wrong about my phone I can surely use it. thanks for sharing!

Version 1.0 released!
I've added a new setting: Screen lock delay. Values available are Immediately / 3 sec / 5 sec. [screen capture attached]
This should solve the locking too fast on phones with furious ghost charging like yours Thanks again for your feedback!

It seems to me that Wake on plug (Settings/Display and lights) has be introduced in CM 10.2 and possibly for some unofficial CM 10.1
Such a feature does solve the battery drain issue in a better way, but SnooZy can still be useful for unrooted phones!

i never needed this app until yesterday when i updated to oreo from nougat. but lineage oreo (unofficial) seems to have removed or maybe just moved the option to not wake the screen on charge and as i use wireless charging that tends to connect / disconnect regularly it was driving me crazy until i found this app to keep the screen off. works great for me and on oreo :laugh:

Best lock application!

Hello!
When I owned the Raphael I used the Smartlock or S2U2 (tested) to autlock the device!
I was wondering what you use to that purpose!
Thanks
Am actually not using any screen lock software at all. When I want to lock the screen I just put the device to sleep using the power button. This has worked very well for me in the past.
I use Throttlelock. Works nice!

A long press on the hangup key (most right hardware button) also locks the screen.
smartlock has been known to cause some problems in the past..I was using TPC's 6.5 ROM and it had smartlock, and when I tried to use a PIN to unlock the phone, (which was requested after the initial sliding-to-unlock motion) the phone froze up. a softreset fixed it, but after that whenever I tried to disable the PIN, the phone would freeze. I'm using S2U2 v2.02 with my tilt, and when I get the TP2 I'll continue using it. (unless smartlock gets those bugs ironed out.)
ok I know this thread is a couple months old, but my question relates to it.
Regarding Throttle Lock, does it have any issues like S2U2 some users are having such as draining the battery?
Is there any configuration for Smartlock? I've been using S2U2 for so long I forgot about it.

I am noticing a mysterious battery drain since installing S2U2 on my TP2. I'm also noticing that the "Device Usage" in the power information screen is a lot higher than the amount of time I've actually had the device powered on. I am also now looking for a good alternative to S2U2. I don't like Throttle Lock (just personal preference).

I'm using pocketshield now, light and low power consumption + it's cheap ! And one more thing there is an unlock with light wich is great ! and many other features....
after several seconds,pro2 will automatically turn off screen and locked,why you still need a auto-lock??? he can walk,why you buy him a walking cane?

The screen goes off and your device goes into standby, but it's not locked. If your phone rings but you missed the call, your screen will be on and will be susceptible to accidental screen taps.
My personal favorite is DeviceLock. It uses zero resources and utilizes the default locking mechanism.

My friend told me of one which scans your eye to unlock it...
Is he telling me prokies

Thanks, ohyeahar. After spending two days trying to get Touchlock Pro to work reliably I installed this and it just works. It's a simple app but it just may be the best find for my TP2 yet.

I tried pocketshield 3.0, but it drains battery and I don't see anything being locked (though it is locked sometimes)
Uninstalled the program but still my battery drains rapidly, using 450mA all the time

What do you use t show current usage?
Can you explain exactly how you are measuring battery drain with PocketShield. I am MUCH happier with PocketShield than the other locking mechanisms that I have tried (S2U2, Devicelock, etc)
But I have noticed that I have pretty fast battery drain - just didn't associate it with PocketShield. With other locking programs I notice that my screen is often on when I take the device out of my holster so I just assumed that they were allowing for increased battery usage. With PocketShield I don;t notice the screen coming on so much.
Why was this phone introduced by Verizon or Sprint (or even HTC for that matter without this issue being fixed better?
I use Battery Log to see the current used.
After 12 hours just stand by the battery power is less than half the full power! So this phone now is useless!!
I will have to start all over again

[Q] HTC Kaiser CPU Doesn't Sleep?

Did a search, and didn't find anything regarding this, so I'll point this out. I've noticed whenever my Kaiser (KAIS100) goes to sleep, it doesn't actually sleep, I can still press every button and the phone will "wake", screen comes on.
When I check Spare Parts > Battery History, it shows my phone's been running for 5days even though it's been on for 10 minutes actual. If I continue to put the phone to sleep that time grows exponentially.
Is my KAIS really sleeping, or is there a bug somewhere?
I'm running l1q1d's latest .32 kernel, with Fat Free Froyo build with system/data on NAND.
Battery also only lasts about 8hrs in "standby", and not even 2hrs with full use. With WinMo, I get about 36hrs standby, and about 5hrs full use.

The phone locks like it's suppose too, but the problem I'm having is the CPU of the Kaiser isn't actually falling asleep. I'm getting the same battery consumption as when the screen is off compared to on, and sitting there (no activity on my part, just leaving the screen on for no reason )
Every so often the phone will be asleep, and the only way to bring it back on is by hitting the power button, but about 95% of the time I can press the call button, end button, OK button, IE button, hell even push down on the wheel on the other side of the Kaiser and the screen will come on showing the lock screen.
As far as the battery capacity, I have not done that, but the phone's been auto-learning my capacity, and it will get to the 2160 units, compared to the 2000 it's always set too, and sometimes reach 2377 units.
I have tried several Radio versions, down to 1.65.xx.xx version (which was the original version on my phone), and no changes, and tried different builds and no change either. DZOs kernel doesn't make a difference either, except screw up my battery meter completely. lol
uhm thats wierd.. i can only unlock through the power button, what i have experienced is that if its conected to an external power source it does reacts to any button I press.... but not on battery... maybe its a build issue... right now im using scoots CM rls 5a, dont remember if warbyte's donut behave like that...

Did some more testing, and found that without it plugged into power it does only respond to the power button, but again it's only about 15-20% of the time, and even those times seem iffy as it just seems like the phone's just slow to respond.
Phone is also somewhat warm as well even when "off", and I do have the phone overclocked to 450MHz, kernel is set to 425 (running a test on speed/stability atm)
At 425MHz it's still reasonably warm, and at 450 the temperature jumps alot.
Anyone else have an issue of the tap sounds when tapping on the screen sometimes not playing? Granted phone quality is great, and GPS is working well, though Camera is broken on my end, even though it was working before.
It sounds like there is a real issue. Some application is running continuously for you, preventing the CPU from going to sleep. I have had that before. Try removing widgets from the main screen. For me, the problem was an app that showed a flip-clock and the weather, and looked just like HTC Sense. I don't remember its name but it used to be popular.
The newest 2.6.32 kernel seems to sleep relatively well for me. Sometimes it wakes on any key, and sometimes it wakes up to a totally white screen. Other times it just plain refuses to wake up. Usually I can coax it back to sanity (from white screen or from sleep) by Fn-Left keyboard softkey, then Fn-Right keyboard softkey.
Your phone should get approx 10 or so hours of life from a charged battery. Less than you get with WinMo, but lots more than you seem to be seeing.

Ok, I'll give it a whirl, and remove some of the widgets I have running, and see if it does help out. Right now though I'm re-installing /system as I tried messing around with the density as 110 seems to work real well with where things are placed on the home screen (no widgets are overlapping each other), but Market won't work, and the Android Keyboard keeps crashing (on-screen).
But anyways, phone's booting back up, so I'll test out the battery life here again, as I got about 95% charge right now, so should serve as a good test for battery life, and CPU Sleepage.
Having a similar issue, seems to behave ok (screen lock comes on when I press power button) but power usage on standby is similar to original poster's. About 8 hours standby. Went to bed last night and it said 66% charged (1300mAH battery) and it didn't last the night. Takes a looooong time to charge to full though so I doubt it's lying about fully charging the battery, suggesting it's using it up at a fast rate.
How do I check background tasks?
Edit: This is with WiFi, GPS and Sync OFF by the way. On the other hand I live in a low signal area (typically 1-2 bars) could it be straining to get a better signal? Used to have an old nokia that used to run itself flat in no time when there was a low/missing signal!
Edit 2 : Figured it out, turns out the ebay app has a service and a process running - even with notifications turned off! Have killed these and see if anything improves
That could very well be part of the problem, although it shouldn't kill it from 66% with just the radio. How much capacity does it calibrate itself to?

Phone Radio really shouldn't use more power with low signal, in fact it really shouldn't affect power output at all (well except the fact that it's on). I have a 1350mAH battery, but it's reading at 2470 adjusted, so I re-flashed a new kernel with the new battery changes, now it's reading 2437units adjusted, which is over 1500mAH for the battery which is not what I own. But on the bright side, my battery capabilities are improving, and the battery meter is starting to read alittle more accurately.

yes, i boutght seidio 1600 mAh, and the kernel ended up adjusting it to 3260 units... (about 2000 mAh) maybe the 1.6 factor isnt right just as n2rjt said, maybe its closer to the 2.0
Seems like ebay may have been the culprit. Killed the ebay process and application in the background and only used about 10% over night (as opposed to over 60% the night before). I'll have to leave it overnight with ebay running again for a proper scientific test next

Yah, I'm starting to run into issues with certain apps keeping the phone awake and not letting it sleep. I kill some of the apps and it actually helps out the battery some.
I installed the original launcher from one of the other froyo builds, but came across with an FC with acore, so now back with ADW.Launcher or LauncherPro.

When you install a app, take a look at its requirements, like "PREVENT FROM SLEEP". You might have a app doing just that..

Yep, most of the apps I download have that. But in sad news, I'm actually going back to WMO 6.5 as I can't seem to keep Android stable on my kaiser.. I've reinstall the same build twice (which I know is not corrupted, as it was working fine 2 days ago), and Market is always corrupted...... So, for now, until I have a secondary phone I can revert too, I'll be going back to WMO for the time being.

Jellybean Roms and litekernel: Bug Reports

Well being I can't post on the development board I guess I will have to post my rom bugs here.
So I hope that thegreatergood will see it here.
RootBox-JB-i927-Nightly-20130212
BUGS
1) Either the new hardware keyboard lights fix by scottbot95 doesn't work or it wasn't included in this rom. I can see the hardware keyboard lights still come on while the keyboard is closed when the capacitive buttons are used. This leads me to believe that the new patch wasn't applied to rom.
2) Bluetooth still not working in regards to audio in, but audio out works and voice dialer no longer screams in your ear.
Confirmed Fixes
LiteKernel-4.2-20130212
1) Battery life... I have no app but the default battery app.
If the use by the kernel would be measured under Android System, then I think there is an issue.
Android System is at 27% after 45 minutes of use while screen is only at 23%.
This correlates unscientifically to what I witnessed in CM10.1 with LiteKernel-4.2-20130211 after 5 hours of pretty regular use playing games, backing up, downloading, and etc. Android System was almost equal with screen on battery usage.
I believe this to be a bug because before I upgraded while using LiteKernel-4.2-20130120, the screen usage was easily double the usage of Android System, under similar use patterns.
I am flashing back to CM10.1 and will test this more under daily driver.
2) The WIFI power manager, am I just missing where to turn it off? I am sorry and the work you do is amazing thegreatergood but it has to be one of the most annoying things I have ever encountered.

1) I had the same issue... But i checked and some times there is a process that tries to turn on the screen, and keeps doing it forever, until you reboot the phone... I use pop up notifications from whatsapp and this happens alot... but sometimes you realize to late.. and the battery is already gone....
2) The same with you... It is really annoying... I already read in a post from dmans.. that he will put an option to disable that...

Battery life tips/tweaks to stop battery drain

When I first got the Note 5 last week, I noticed the battery life wasn't so great. After making some tweaks I've noticed that 1) Android system isn't the number one thing eating up my battery 2) Cell standby isn't consuming more battery than my screen anymore and 3) Screen is the number one thing consuming battery and I'm getting fantastic screen on time. The first attached pic shows stats from my phone being off the charger for almost 8 hours and I was connected to my wireless earbuds via bluetooth and streaming pandora for almost 4 hours while traveling to and from the gym and during my workout (all over the network, no wifi but when I'm home or in the office, I'm always on wifi) plus I had about 1 1/2 hours of SOT. The Second pic is day 2 with 1 day and 2 hours of use with 37% still left and 3 hours of SOT. Also, I have Google Now running, Facebook, Instagram and Twitter constantly running and I maybe lose 1% battery life every hour or longer when I'm not using the phone.. I'd like to thank @rlsroufe for his debloat list because that was a big starting point.. Here's what I did:
-Disable AT&T/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 (Huge battery drain, causes play service and/or Android system to go nuts)
-Turn off Android Device manager (Lock Screen and Security —> Device Admin)(Also causes play service drain)
-Disable Unnecessary Sync Service
-If you use Adguard, turn it off when you don't actually need it and just flip the switch when you do
-Turn off S pen Alerts, pen detection, and S pen sound and vibration (will still work exactly the same)
-Turn off Enhance4GLTE (basically voice over LTE, makes cell standby consume a lot of battery)
-Turn off 'Always allow scanning' under advanced wifi settings (Allows apps to serach for Wifi even when wifi is off)
Reboot and enjoy..

When I first got the Note 5 last week, I noticed the battery life wasn't so great. After making some tweaks I've noticed that 1) Android system isn't the number one thing eating up my battery 2) Cell standby isn't consuming more battery than my screen anymore and 3) Screen is the number one thing consuming battery and I'm getting fantastic screen on time.

Turn off the phone. Best battery saving advice
Sent from my SAMSUNG-SM-N920A
How exactly is that turning off the phone? It just disabling things that aren't useful to me and getting good results..

I think it was sarcasm.
I had posted this in another thread, but using package disabler to disable "s-finder" seemed to have made a large difference in battery for me. I (personally) usually keep location services and android device manager active, however.
One thing common with many android phones is that for the first couple of days after you first get the phone (or factory reset it), location services tends to draw more power when compared to after you've had it a while. I have nothing to confirm this (and I've been too lazy to try and verify it), but I suspect that location services keeps a cache of cell phone tower locations... so the drain would be higher while its still building up that cache.
Yeah I feel like disabling S finder helped as well.. I consider that samsung bloat as well but I'll add that to the list, thanks. I keep location service on as well but I turn off location history which is what I think was causing stuff to go nuts and def noticed a difference right away. Device manager I don't really use because I noticed if you factory reset your phone via the phone recovery, you still have to sign into your google account before you can do anything with it so that's nice.
Yeah that sounds like a logical theory and could very well be what was draining battery. But literally 2 hours after turning off Enhance4gLTE, cell standby dropped and noticed battery life was a lot better. There's been a few threads on that as well as VoLTE (tmo equivalent) that suggest that's the issue for drain as well.

Can you share your disabled list in Package Disabler Pro please?
Got this via @rlsroufe and @mcdavid
FYI - There's an Extreme (left column) and Basic (right column), I just went with the Basic one. Green Means I left it alone, Orange means I disabled it and Yellow means you can but don't have to. This is for the Tmo variant so some things wont be on this list so I just went one by one and did it just by typing in the last word of the application. Anything that I actually used I left alone but you can mix and match if you want and see what works best for you.

Okay.. So Samsung made this SUPER ambiguous.. But the "Disable Pen Detection" setting.. Are you saying that that toggle needs to be ON or OFF? What does the setting do anyways? I can't understand Samsung's wording in the settings..
Lol yeah, there was a big discussion in anther thread about that. Putting it in the 'Off' position turns it off which is what you want.. I believe it just turns off the feature when you walk away from your s pen and it warns you.. I could be wrong tho but since doing it, nothing has changed with the S pen and it all works the same exact way when I pull the s pen out

Haha, I think there's a setting for what you described (other than pen detection) but have you noticed the battery life is better when that setting is turned off? Or is it not noticeable?
I'm not 100% sure because I did everything pretty much at once. It does say it might help save battery so that was enough for me. Everything has been working great so far tho, finished charging my phone around 12 today, left it for 2 1/2 hours and didn't lose a percent even tho FB, Email, App update and Text messages were coming in so I think it's a combination of everything

Wow that's really good! I might have to try it out and see if it makes a discernable difference. Thanks!
No problem. You'll def notice a diff in standby time..

Actually leaving it in on position turns off pen detection which saves battery. I am rooted, checked with SQL editor.

Someone said the opposite and gave the same reason why lol. D*mn Samsung for not be clear

So what is the verdict? Off or on?
LOL says in my settings for this "turning off pen detection when the pen is attached can extend battery life".
So i turned mine OFF
My secret is leaving it charging all day, all night, all day etc. That's the only way.

Based on rlsroufe's SQL dump, the option should be ON which disables pen detection.
When you pull the pen out and the phone no longer 'sees' it, it uses the motion detector to see if you are walking away. If you go like 12 steps you get an alert.
Turning this option ON, disables this detection when the pen is attached to the phone.
Hey @oka1 can you please close this thread or disable the comments. I will no longer be supporting it because I no longer have this phone. Thank you

New Stock ROM 20170814 and OTA not working!!

Afternoon Gents,
Elephone have posted another 7.1.1 stock rom for this unit dated the 14.08.17
http://www.elephone.hk/downloads
Fixes?
* This one looks like it fixes the severe battery drain as the unit now correctly powers the screen down when in standby.
* Time for first GPS fix is greatly improved.
* 5th July Android Security Patch.
Basically we're back to the stability of the late 6.0 builds with faster GPS.
Here's the annoying part
I've been in discussions with Elephone via FB and email to their Engineers. They are insistant that this update has been released OTA on Mon 21st, BUT my phone never got it. I've done repeated checks on multiple fibre, VDSL and VPN connections and it either returns no connection or Device up to date I've had to manually flash the scatter file from their website then flash the phone, which obviously completely resets everything.
Hi, on Monday 21, i have receive this update.
Before this, no problem for me with my S7 4/64 on Android 7.1.1...
Now, after update : very big battery drain, and zero notification , exept SMS ( no notification of games, app ....)
So there is a big problem
Have you done a factory reset. I have had similar issues after an OTA, especially with the fingerprint scanner. A full reset fixed it.
Factory reset done , so :
- Battery drain : the same after reset
- Notification : sometimes it work, sometime no ????
- LED notification : OK
- Charging : return of the sound when connect / disconnect charger OK now

Hmmm. Interesting. I have an S7 64/4 and on the latest update:
* Battery drain is significantly reducced. Previously this was caused by the screen not turning off when going into standby leading to rapid battery drain. My screen now goes completely off after 30 seconds and I get about 36-48 hours on a charge.
* LED notification is fixed, although the colours marked in the menu are wrong. I think there are 7 colours in the menu but only 3 work.
* Charging sound functions normally.
Did you use the OTA? What happens when you use the upgrade on the website? I wonder if they may be differennt somehow.

For me no problem with standby, my screen is always turn off, but, this morning, in two hours of standby, about 15% lost on battery

Oh well. If it works for you, that's the main thing. Mine was horrible on the May release.
Are you using the Elephone cover with the window in the front?
I'm using the silicone cover sold with the phone.
Why this question .

The extra cover you can buy with the window in it works with the Hall sensor in the phone to turn the display to the clock then off. In the May/June firmware, this process wasn't working, the screen always stayed on leading to terrible battery drain

It's not only that the screen is always on but the CPU scheduler for the device is badly optimized.
It won't properly shut down the performance cores or multimedia cores when using phone only for simple stuff like reading web, watching youtube or sms.
Plus when the phone goes to sleep, all cores are on at 1GHz randomly.
