[Q] Cannot slide to unlock phone when battery is very low? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have a problem: I cannot slide to unlock the phone when the battery is very low. I have to swipe the widgets page on the lock screen to open an app and then click the back button to get to the main pages. Why is this?

Your battery is low and power saving has kicked in. Recharge the battery.

Can I turn off this power saving feature so I can still use my phone when it's at like 5%? Seems silly I can't actually use the phone other than its widgets until the full duration of the battery is used.

I don't see anything there nor do I see anything here: http://cdn.gottabemobile.com/wp-content/uploads/2013/05/Better-Galaxy-S4-Battery-Life-Tip-11.png.

I see "on" turn it off.

Ok, I just thought that the things listed under there were the only things for Power-Saving and none of them were related to my problem. Thanks.

[Q] Has anyone found a PGM replacement?

Hey guys
Long time Galaxy Nexus / Galaxy Note 2 user here.
One of my fave apps was the PGM because it allowed control of the phone without hitting the unlock button to unlock it.
I know the dev (who lives in Poland) hasnt gotten an N4 yet, so he hasnt been able to write the kernel tweak yet.
Anyody found any options?
I have been using the app Sleep Tweak. What it does is if you get a text it wakes the phone but doesn't turn on the screen. If you pick the phone up within X seconds after receiving a text the screen turns on. Same with if the phone times out by itself if you pick it up within X seconds it will turn the screen back on. Not the same I know but it lets me decide whether I want the screen to turn on for a text or something.

No answer for you, but a question..
Wouldn't something like PGM (Nexus) drain the battery? As it would require the screen to be "on" to detect any type of touch from the user?

The battery drain was very minimal on my gnex when i was using it, maybe 5% tops.

No,
Snce it's written into the kernel itself the device still deep sleeps and so the effects on battery are minimal.

I mean, that's not bad at all, but man I wish I had 2 N4's I could ship this guy, so we could finally get that.
No lie, it's the ONE app I NEED on a device

5%? No. It's way less than that. When I use it it feels like it has absolutely no impact on battery life because it's a kernel module.

Power Saving Mode Tip - What I learned

.
I was messing around with the power saving mode just now. I realized that when I tick-on "Screen power saving" I can notice a huge slow down on the whole ui. Now remember everything else is ticked-on including the cpu limiter. But with "Screen power saving" turned off, I couldn't tell the difference between power saving mode and non-power saving mode. Which leads me to conclude the "Screen power saving" is doing some major cpu calculation which might actually not be so great as it defeats the purpose of power saving.

That power saving mode and blocking mode are the stupidest two things that they pushed on android.. I never used thise things. Also, that screen brightness adjustment in notification menu is so annoying,and I never touched it. And whyv they added those extra toggles in notification menu next to sound,wifi ,mobile data,etc so now everything slides from side to side and I always press something that I don't want. Or maybe there is a possibility to turn those off and I can't find how to..

Toggles can be customized even on stock.
And power saving mode really does save battery, and its customizable.

It saves battery but it destroys performance. It is acting like galaxy ace when on power saving mode . Please show me how to customise the toggles, because I can't find out how after 10 days of looking into the settings. Can I move the brightness adjuster too? Thanks

Sorry, didn't realize it is a 4.1.2 feature!
But I don't understand how you can say that power saving mode destroys performance, I hardly notice any difference in normal usage. It's basically just the cpu locked at 1 ghz.

The screen power saving mode does something with the screen's refresh rate, if you have it on you will notice the screen flickering in a very fast rate, so the slow down in the UI is probably because of the screen is skipping every other frame making it seem like it slowed down when it is not

Does make sense, but would that really save a lot of Battery? I think the sweet spot now is to just tick on CPU Limiter while leaving everything off. [Obviously people who use CPU apps don't really need this feature as they can modify the CPU even more] Too bad I really don't use this feature much as of yet but will report back if I find anything new. I'll try to use the phone for a couple days with just the CPU Limiter ticked on this weekend.
If you want to save power on your Note 2, you might use SetCPU, Screen Filter & Juice Defender Plus, these apps help me a lot to save battery.
Because it limits your screens fps to like 40 or 30

I strongly believe it is lower then 30FPS.. Perhaps below 25fps.
HOWEVER if you uncheck Screen Power Saving, the FPS returns back to normal. I usually use Power Saving mode with only Power savings on, this way performance is not affected.
What's interesting is that I've been testing power save mode on some pretty high end games like modern combat 4 and nfs most wanted and you only lose 4-8 fps on average, but it still remains over 30 fps.
This is with all the options ticked in power save mode. For gaming while off the charger, it would help extend the battery quite a bit.

If that is true, I hardly find a reason to NOT use power savings until more graphics demanding games come out. I'll also test it out on Deadzone.

Well those extra fps could come in handy, but if power save gives extra playing time then it might be worth the slight loss.

Exactly my experience too.
Also, it's not the fps getting capped, lower fps is just a result of capped cpu frequency, but the refresh rate is capped, which could lead to a certain amount of flickering even though I cannot see it. Correct me if I'm wrong.

Power modes like windows

Hey guys this might be a strange or stupid question.
I'm looking to see if anyone knows of a silent app or some flash able mod that can do the following.
plugged into a power source the screen timeout will change to say 10 min and brightness to 100%. Then when I remove power the screen will go to auto brightness and timeout in 1 min.
I'm kinda surprised android didn't ship with this feature. A feature I really think needs to be implemented, or if I'm just so stupid I can't find this option, just call me a idiot and tell me where in settings it is lol.

well, it doesnt exist in the system but you could get this function with Tasker
i would imagine that it doesnt exist because it is such a rare case scenario, considering the device is designed to run disconnected from power....its a mobile device
Maybe one of those power or battery saver program can do it. But I guess you can try Tasker.

Brightness Slider Gone

I'm rooted running stock with no mods flashed and I'm not sure why but sometime over the past few days my brightness adjuster has disappeared from my notifications. I enjoyed having it there and if it's just a setting I've hit that's be awesome. Otherwise I might just flash a rom to fix it.

You can see if it is turned on.
Click on settings

Display
Notification Panel
Then click Brightness Adjustment
If it unchecked that is why you don't see it. Unfortunately I have no clue why it turns off if you are not doing it.

No problem, Samsung had to move all the settings around in 4.2, making it harder for everyone

It disapears when your battery hits 5%
Comes back when you are at 6% or higher

Yeah mine has disappeared too, this is the second time I reset my phone once and it came back now it has happened again. No one seems to know why...
Night Mode
If you have the app Night Mode. Turn it on (start) then turn it off (stop). The slider should appear again, as long as you have it checked in the settings.

Deep Sleep?

I was wondering if there was a way to make my phone wake up faster because there is a significant lag when turning screen on. Minor, but would be nice. Thanks!

Significant lag? How important are you that you need back that extra 2 second it took to wake up?
