[Q] Power Saving Mode question

Have a Rogers SGS2 LTE. I have power saving mode enabled in the settings. It comes on at 30%, and shuts of wifi and bluetooth if not connected, dims the screen and reduces the screen time-out to 15 seconds.
My question is this. Last night it went on at about 9 pm which was fine, and power lasted til I went to bed. In the morning after charging, the time-out is still at 15% and the bluetooth is still off. Does the power-saving mode not change the settings back to the original once the power is over the threshold, in my case 30%?
Secondly, if I'm using a product like Juice Defender, should I be disabling the built-in power-saving mode and letting JD do it's work.
Thanks

i just got a Skyrocket and also noticed the green mode doesnt undo itself upon charging, on 2.3.6. Annoying! i changed my setting to 10%

Ideally you should only have one app managing low power conditions. Avoids any chance of conflict. If you're going to stick with juice defender, use it by itself.
Keep in mind sometimes settings get messed up. Once or twice over a long span isn't too bad. Something messing up more than that likely has an app forcing undesirable settings.

Bad Battery Drain With Airplane Mode On

I have been experiencing this issue for a while & not sure what is going on. I had my Transformer fully charged the other night. I turned on airplane mode & hit the power button putting it to sleep. Now I didn't touch it for 36+ plus hours & the battery had drain down to 53%. I know people have experienced similar issues & have used Auto Airplane Mode app but it didn't help my problem. When I go to battery use in settings tablet idle is 75%. Really?
Do I have a bad battery, an app causing the issue, or something else? WIFI is off so its not like my Transformer is accessing the internet. If I totally shut it down I only will loose couple percent. Is anyone else having this issue?
If it is app causing the problem then I want to unroot & basically wipe my Transformer & start all over.
Rooted with BRK's Kit
Stock ROM
B50KAS - Serial

Check for program installed recently. In my case, the Skifta program cause the battery drain (i test with airplane mode too). Remove this app and my tf101 battery back to normal.

how to get full brightness on low battery?

when my battery is low the tablet dims. how do I remove this setting?

I would like to know this too. I realize it's a safeguard because a complete battery drain sucks for this type of battery, right? But a forced always dark kind of sucks compared to a warning forced dark that you could change back.. feels... Appley.

Hi you two, all you have to do is go into settings and then you should see 'Power Saving mode' Under storage and above battery. Simply turn on power saving mode momentarily and then you can untick the screen power saving mode and then turn off power saving mode if you wish to.
This is on the settings for JB, I dont know if this will be the same as the ICS settings, if not just have a look around in settings. It should be in there somewhere.

no effect changing that settings
I already have done this: "all you have to do is go into settings and then you should see 'Power Saving mode' Under storage and above battery. Simply turn on power saving mode momentarily and then you can untick the screen power saving mode and then turn off power saving mode if you wish to."
However, my screen stays gray and i can't see nothing more bright... my device is a samsung galaxy note 10.1 gt-n8010 with android 4.1.1 and kernel version 3.0.31-541027
Any help appreciated because this is very annoying.
Thanks,
Miguel Real.

In the same boat here, anyone have a solution?

I was wondering the same thing

Did anyone ever find a solution to this? The screen dimming is a pain in the ass. I'd rather burn the last few minutes of power at full brightness.

This is my only problem with this tablet. I would really appreciate if anyone came up with a solution to this

I guess there is no fix without rooting? Bummer. Some things about this tablet are just so blatantly annoying I can't figure what the designers were thinking.
Hopefully the kitkat update will provide options.

It is protecting the battery. You dont need to drain your battery empty on every cycle - and it is only making bad to the lithium battery to cycle is empty-full all the time. The problem with lithium battries have, is that if the battery drains too empty, it wont start to charge. It is dead. There are safety mechanics to prevent this to happen, auto power off/shutdown features though... But when the battery is 5%, it turns the display dim to get you more time to plug it in. So, if you want to keep your battery good, dont cycle is every time from full to empty state. And dont let it to auto shut off, it may go too empty and the battery wont start to charge anymore.
It is a built in feature and Kitkat wont change this.

Prevent medium power saving mode from disabling background location access?

Ive got a SM-N770F/DS and I always have medium power saving mode on. I have also always had an issue with Google Maps not wanting to detect location after I turn the screen off. I assumed it was a google issue until I turned optimized power saving mode on today and Maps suddenly started reading my location and giving directions while the screen was off. Is it possible to disable the "prevent background location access" part of medium power saving mode? Long pressing my power saving settings doesnt give any options to do this, im thinking my only option is to root. Would rooting fix this? If so, does anyone know of some roms on here that would allow me to do this? I dont care about much else from the rom, I like the phone as is and this is the only issue I have with it

Do not toggled on any power management other than the power mode (optimized) and fast charging.
They screw up functionality and increase battery usage on my unrooted 10+ running on Pie.
In Developer options>standby apps all buckets should show as active otherwise power management is active. Android will manage apps well without any power management options turned on. Track down any remaining battery hogs on a per case basis and deal directly with them. Sometimes closing the window gets it done like with Brave. Others need to be dealt with by package disabler and/or Karma Firewall.
This may or may not help you.
Gmaps is crapware. Runs best on original factory load and is a parasitic drain wanting to constantly run in the backup from boot sucking up battery and bandwidth.
Unlike you my goal is to keep it from doing this
Also review Gmaps notification and other settings. It's a mess; buried settings galore.

I feel like I have experienced the opposite. I felt like my battery was draining faster with optimized on today (2nd pic) compared to the past few days with medium power saving on (first pic). Obviously more testing needs to be done to see. Going off of the pics I lost about 50% each day, so optimized seems to be worse for battery life but the reduced screen on time makes up for it in this scenario

Android seems frozen with black screen

Android 9 on a Samsung SM-T290 tablet.
Had used my tablet, turned off screen (click Power once), and put it down. Some unknown time later, picked up tablet, clicked Power once, screen did not come on. After clicking Power a few times, held Power down thinking somehow tablet had shut itself off completely. Instead of booting, I got the choices "Power off / Shutdown" and "Reboot". Shutting down and rebooting worked. No sign of problems.
Some time ago I noticed my Uptime seemed large -- I think 400 to 600 hours.
What would cause Android to get itself into a state in which it is still running enough to offer a Power Off menu, but in which it refuses to light up the screen?
In particular, is there any problem with running too long without shutting down and rebooting?

My guess is that in your Android the Doze mode is enabled.
FYI:
Starting with Android 6 Marshmallow, the Doze mode feature was introduced. This feature is designed to give a new breath of fresh air to battery consumption and in general battery life.

No match when I Search Settings for "doze".
Under Battery -> Settings there is an
Optimize settings​Save battery by optimizing your settings when you are not using your tablet.​It's a toggle, it is toggled OFF.
I think at the moment I turned off the sceeen, I was im a browser on an obnoxious web page. Maybe their clever Javascript tied something into a knot.
I'll try to notice when I pass 600 hours of Uptime.

If it has the doze feature, it would be a background process that you would see no controls or settings for. It is a feature in the kernel that runs at and below system level and you can't "see" it if you look for it.
Doze puts the device to sleep, it effectively freezes everything from the kernel level all the way up through system/user level and turns everything off without actually powering down and stays in that state until you "wake" it.
An example would be a Kindle Fire HD tablet that I had with doze, I forgot it was on and running a PSP emulator and I put it in a draw for many weeks, when I pulled it out of the draw and hit the power button, it woke right back up straight to the enulator and the game I had running and still had 60% battery.
