Quickboot? - BlackBerry Priv

Someone on the Blackberry sub reddit has found something in the developer options called Quickboot. I can't find it on my Nexus 7. What is it and what is it used for?
(source: https://www.reddit.com/r/blackberry/comments/3tpwy0/anyone_noticed_enable_quickboot_mode_on_priv/)

It's a feature on cyanogen os that cause the phone to enter airplane mode and close all apps when turned off, mimicking a state of being turn off. This allowed the phone to look like it takes only a few seconds to boot

Sounds like a laptop's sleep mode.

Sounds similar to the safe mode function that it offers, if you long press the shut down option from the shut down menu, it'll ask if you want to reboot to safe mode, which disables all 3rd party apps.

How to easily screw up your phone

Hmmm... I think I just found a way to really screw up your phone... let's see what you think of my theory:
1. Put your phone into Airplane mode. This will completly turn off all the radios in the phone.
2. Go into settings and set an unlock pattern.
3. Put your phone into standby mode and turn it back on.
4. If you use up all of your tries at the unlocḱ screen you will have to enter your login details to unlock it. BUT THE PHONE IS STILL IN AIRPLANE MODE. Hence, the phone will not be able to connect to Googles servers for verification. And the worst thing is that not even a shut down of the phone will remove the airplane mode. Not even a removal of the battery.
THe only way to get out of this is to do a hardware reset of the phone.
What do you this of this?
I am not gonna test my theory since I don't want to risk having to do a hardware reset.
I think before the phone tries to connect to the Google service it will prompt you with a 'turn off airplane mode/turn on mobile data/WiFi' option, like it does when you open an app that requires WiFi or GPS when those radios are switched off.
Try it

Nah... I am not going to get close and personal with my theory on this one... Just let's hope you're right... someone else might need to do a hardware reset?

Alarm while phone is off!!

Hi, has someone developed a way to sound the alarm when the phone is off?? I saw somehere that you need to program the alarm in the BIOS.
I really hate to call these 'smartphones' when a basic phone would do that!! Alarm clocks are a passe anyways!
Flight mode is the way.
It is useless to switch off the phone...in flight mode the battery has almost no drains (1% at most).

That's because when you switch the phone off IT IS OFF.
A Nokia, say, doesn't switch off - it goes into flight mode and switches the screen off.
If you notice a Nokia phone loses battery power even when swithed off because in fact it is still on. That's why the alarms go off
Therefor: Switch to flightmode and turn the screen off = same result - but smarter !!!!
Why then there is a 'Flight mode' option in Nokia as well? Cant seem to understand this??

It's a feature Nokia added so people could turn the phone signals off manually in situations where it was unwanted. On planes for example.
You could try this
Ageye G-Alarm, is isn't free but claims to
"Save battery power overnight
Using the integrated flight mode you can turn off the phone and therefore minimize the battery drain until the next alarm. Afterwards G-Alarm automatically turns your phone on again."
Same thing, but might do it automatically, but its too much for me, I don't need all the functions so haven't tried it.
Thanks! But would not want to use two third party apps just for the alarm! Looks like I might need to get back to my old & trusted alarm clock or use my other Nokia phone!

Which two 3rd party apps are involved in using flight mode? (by my count none are used)
You can even configure a long hold of the hang-up button to enable it if you want in button config...

In Flight mode, you can still use your phone in "off-line" mode, you can even use WiFi... so saying that turned off Nokia is actually still ON - only in flight mode - can only say someone who doesn't have a clue what is going on inside the phones. Turning Symbian phones OFF/ON means soft reset, does turning Flight mode ON/Off means soft reset in any phone? Of course not.
Take your laptop - there is power save mode, sleep mode and hibernation. But OS (say Windows) is still running, even it is on the lowest possible level, so a few external inputs (keyboard, mouse, modem), most of them you can specify in Bios, can bring the system from stanby or even hybernation mode. When you turn off your Nokia, operating system (Symbian and Maemo too) is completely off. But the internal clock chip is still running, althoug only on cca 1/100th of clock rate. When you turn phone off, the info from the alarm clock is written to this chip, telling him after how many those slow cycles he suppose to wake up (if there is anough power from the battery left). Would be easy to implement this to any phone hardware, HTC, Sony ... they'll just have to run something else than Win OS. So blame the Microsoft - but go easy on them - it's relict from the old ages of PDA, when Windows and phones were two totaly different things. Whatever I wrote is not a 100% accurate, but I was trying to make it simple and uderstandable. BTW any phone (HTC also) is loosing battery capacity when is OFF. Actually, take the battery out and it will still loosing power, after some time in even more (in hot and humid conditions) than when you leave it in the deep level stage inside the Nokia.

[Tip] Keep Wifi On After Reboot

You may have noticed that every time you reboot your Adam, Wifi is off on bootup, even if you had turned it on before shutting down.
This is stupid easy to fix.
By default, the Adam is in Airplane mode. This mode causes the Adam to turn off all wireless communication on startup(as well as when you turn airplane mode on). And will allow you to turn the Wifi antenna on, but automatically disables it at boot.
Simply press and hold power for 1 second.
Then press airplane mode.
If you had Wifi on before(but it is off now), it will turn on when you do this, and the next time you reboot, it will stay on.
NOTE: This is true for the 3G models. It may work differently on the Wifi only models.
P.S. If this is the wrong forum for this, let me know. I just thought it might help some people here because several of us told the devs this was a bug, but I think it is actually just a dumb feature(Airplane mode should not be on by default, perhaps there is some international policies that required this?).

Shut down

My dell inspiron 15r 5521 when it shuts down it'd screen goes off but the lights stay on for about three minutes when the screen has gone off the only way to completely get the lights to go off is to hold down the power button for like ten seconds I know it's not good for it but sometimes when I'm in a hurry I have to this computer is like three weeks old so what's wrong with it also how do I keep wifi on when closing the lid is there a registry hack for that? And what is fast boot
Sent from my SGH-T759 and if my gramor is wrong it's probably because I sent this while walking or rushing before a class starts
The default "shut down" behavior on Win8 is to reboot the computer and then hibernate right before the login screen. This enables the "fast boot" you mention where the computer can be "started" (actually resumed) in seconds. The best solution to this is just never shut down (seriously, there's literally only a couple reasons to ever do this, and I don't think you're adding or removing hardware every time you run between classes...). Use sleep (suspend to RAM; near-instant both to suspend and to resume, draws a tiny bit of battery power but you can leave the machine that way for a week, usually) or hibernate (suspend to disk, takes a while - though it shouldn't be anywhere near 3 minutes - but then shuts down completely and uses no power at all). As a bonus, these methods don't require killing all your programs and starting them again, so you can resume exactly where you left off (even, for example, resume an interrupted download in most cases).
Disabling Fast Boot (look up how to do it, I'm not going to bother holding your hand all the way to the search box of your browser) would let you power the machine down more quickly, but will make bootup somewhat slower (though Win8 still boots up quickly). Disabling Hibernate will also disable Fast Boot, but I don't recommend disabling Hibernate unless you're seriously short on disk space (it reserves a "hibernation file" that is the size of your system RAM). In any case, it's probably just fine to move your computer while it finishes "shutting down" anyhow, though; no need to wait until all the lights are off (don't bang it against anything while the drive is spinning, assuming it's not using an SSD, but that's never a good idea anyhow).
As for leaving WiFi on while the screen is closed, the most likely only way to do that is to modify the Windows power settings to select Lid Close Action: Do Nothing (it will still turn off the screen, which will save a bit of power). However, this just leaves the computer running and will drain the battery almost as fast as using it. A few Win8 machines have a special low-power mode called "Connected Standby", which is similar to what smartphones and tablets do when in sleep mode, using more power than a full suspend-to-RAM but turning off almost everything else except the radios. If your computer doesn't already do this while in sleep mode, though, you're probably not going to be able to enable it; I believe it requires hardware support.
WiFi turning off when you close the lid is normal. Closing the lid *under default settings* puts the laptop into sleep mode. Sleep mode disables WiFi unless your device supports connected standby, which yours doesn't to my knowledge.
Advanced power plan settings will let you set it so that closing the lid does nothing. I would recommend creating a new plan if you want to do that.
Pausing downloads is exactly why I prefer torrents when available, sadly few downloads are available as torrents
torrents pause when you get disconected?
torrents break up downloads into much much smaller segments (few kb to 1mb max) and download each segment independantly. Lets say a 5mb file gets broken up into 10 half mb files instead. The torrent client will download them individually, if the internet gets cut midway through file 4, when you reconnect to the internet it still has files 1, 2 and 3 so still has 30% of the progress already. It can just continue from file 4. So yeah, torrents can survive internet disconnection, sleep, hibernate and even a complete system reboot (literally, shut down the machine, start it up 5 or 6 days later and you will be almost exactly where you left off). At the most you might be 1mb behind but as torrented files are sometimes a gb or more that is pretty insignificant. And even on a dial up connection 1 mb is not going to take long to restore.
For smaller downloads like a single MP3 track or a word document its not worth it. But I personally have an internet connection running at 100-200 kilobits per second, so if I want to download a 1.5gb linux distro the ability to pause the download is a huge benefit.
Sadly, few downloads are available as torrents, they are also peer to peer so that relies on a peer being available (basically rather than downloading the file from a dedicated server I am downloading various parts from different people who also have a torrent client and the same file).
Too many people also associate torrents with piracy. It is true that you can pirate movies via a torrent yes, but that doesnt make torrents illegal in any way. It is common for very large files to be offered as a torrent purely because of the pause/resume functionality. Most major linux distributions offer a torrent as a major distribution method.
My preferred torrent client is bit-torrent, heard a few recommendations for μTorrent.
Back ontopic.
Done a little more research. Pretty sure now that your system will not have Connected Standby so you are stuck with wifi turning off when you enter sleep mode. Chances are if you had it then it would already be enabled.
Not really sure whats happening with the lights. In order on the laptops I have had access too (including my old inspiron) on shutdown the display would shutdown, then the fan would cut off and the lights would go out and that would all be within 2 or 3 seconds start to finish (usually the display > fan transition was longer than fan > lights). Never seen 3 minutes myself but I doubt the battery drain from it would be significant so I would perhaps ignore it as an odd quirk, perhaps keep an eye on it.
Yeah idk about lights staying on that long because I'm pretty technology savy and we have a 2011 inspiron that manily my syblings use and it dosebt have that problem but I guessing I'll just keep an eye on it but does anyone know of any hacks to keep Wi-Fi on.

The wifi on thing is hardware. The system almost completely shuts down in sleep mode. It keeps a little bit on to keep the RAM active and a few other minor tasks but for all intents and purposes its completely shut down. Only if your device supports Connected Standby can it enter sleep mode and keep wifi on. But at the moment only intel clovertrail chips support it. I think the haswell may be getting it too.
There wont be anything like a registry hack to keep wifi on. Wifi off in sleep mode is a trait of all major desktop systems. The only major operating systems which do leave it on are probably android and iOS and they are movile systems which never go into a true sleep mode. They just dim the display and prevent user applications from being run (unless they are given explicit permission to run when locked).
If you really want wifi on when your lid is shut. Go into the power plan settings, create a new plan. Go into its advanced settings and there is a section about what action should be executed for various things like pressing the power button, sleep button (if applicable), reset button (if applicable) and closing or opening the lid of a laptop etc. By default close lid will trigger sleep mode. You can hit the dropdown box and set it to do nothing. Even when set to do nothing, when you close the lid the display will turn off. But otherwise the laptop will remain fully powered on, infact if you hook up an external keyboard, mouse and monitor the system is still usable. The battery drain will be almost the same as leaving your system idle for ages, but as the laptop wont be in sleep mode the wifi will remain on. Its worth looking through that menu anyway, I personally rebind the power button to enter hibernate
maybe the “fast boot” i

I hate being the noob here, but fast boot does really restart system when shutting down?
I thought that it starts to shut down just like when not using it, but when only the kernel and drivers are still running, it hibernates those instead of a complete shutdown. This would make the black screen appearing after the 'Shutting down' message clear, as it is used when hibernating the system.

It shuts down, rebooys and immediately hibernates. Then when you go to hit the power button to turn the system on it appears to boot ridiculously quickly because it only has to wake from hibernation. This might indeed cause the lights to stay on a little longer

Is this really happen after Windows 7? I didn't restart my laptop and only use sleep mode since upgrade to Windows 7. I only shutdown or restart when Windows Update (sometime I force to not restart), software install, hardware fix.

For me everything slows down after 1 week without full shutdown/reboot, just like on Win7. This is why I cannot believe that it really reboots when performing a hybrid-shutdown.

What did you mean hybrid-shutdown? And what you did when you full shutdown/reboot?
I'm not experiencing the same issue on windows 8 myself
Hybrid Boot (that's the correct name for hybrid shutdown / fast boot) does not fully shutdown computer. The process is divided into two parts: log off all users and hibernate remaining system/kernel part. So if you have misbehaving drivers/services, then computer can become unreliable after some time.
When you restart computer, even with fast boot enabled, system goes to full shutdown without hibernation part, so this can temporarily resolve problems like above.

Can we have a confirmation about it? Because I enable/disable fast boot all the time...
You r right if you don't want that problem disable the quick boot options in power management......

A quick google on the issue brings this up
Windows 8 changes this by shutting down as far as closing the user sessions. At that point, instead of continuing and ending system services, and shutting down
Session 0, Windows then hibernates. This is called Hybrid Shutdown. The steps are shown below.
Click Shut down.
Windows broadcasts messages to running applications, giving them a chance to save data
and settings. Applications can also request a little extra time to finish what
they’re doing.
Windows closes the user sessions for each logged-on user.
Hibernate the Windows session.
Essentially a Windows 8 shutdown consists of logging off all users and then hibernating.
http://blogs.msdn.com/b/olivnie/archive/2012/12/14/windows-8-fast-boot.aspx
A full reboot of windows 8 takes a lot more time than the hybrid shut down. When you reboot, the actual shut down procedure of windows 8 occurs, without cutting off power, ofc.
Therefore, hybrid shut down aka fast boot has nothing to do with restarts.

Marshmallow "Hibernate" Mode

Is there any possibility of having a "Hibernate" mode in Android Marshmallow, or is this already implemented in any roms? Like, it saves the current state to memory before it powers down so that when you turn it back on again, it just resumes that state in a few seconds instead of taking a few minutes to boot up from scratch?
No. Sorry This doesn't exist and nothing like it
That's what doze is trying to do, it essentially hibernates your phone while on.
But to completely power off the device then power back up quicker than normal like your TV, does not exist at all anywhere

I know at least HTC phones used a hibernation mode, they called it quick boot or fast boot though. Not sure if they still have it on current gen devices.

Yeah, I honestly hated this feature.
When holding the power button, you only have a "power off" button if you didn't have APM installed. If you were trying to fix an issue via rebooting, you had to do a hard shutdown/restart.

I always turned it off because it meant you couldn't use fastboot.
