    Under the Power settings, there's an option called Fast Boot. Is there any reason to NOT having this option checked? I'm not turning my phone off very often, but why would I NOT want it to start back up as quickly as possible when I do? I just thought this was kind of a strange option.

    With FastBoot on you never actually shut down the device while rebooting and if your trying to fix something that is glitched it will rarely help to reboot with FastBoot on. If you don't reboot often just disable it.

    Ahhh....So the phone never actually powers completely down when Fast Boot is toggled on, then. I see. Thanks!

    I don't think this is accurate. If I shut my phone off, not just restart, it doesn't stay on. It shuts off completely. I might be wrong, but I don't think it keeps the phone on

    No it doesn't keep the phone on, it's meant to help power on your device quickly, usually from a cold-boot.

    The main issue with it is for those who need somewhat regular access to the Bootloader/Fastboot Mode or Recovery, which isn't a ton of people, which is why it is checked by default.

    I was wondering this myself. Seems that there must be some kind of disadvantage, otherwise fast boot would be regular boot. Seems like it kills all operations as all my apps are shut and restarted when I fast boot (as if they were force closed).

    Well the question is, why have it as an option at all. Why not just always make the phone "Fastboot" ... is there some reason you wouldn't want it to fastboot? What is different about the boot sequence?

    It doesn't "keep the phone on" It keeps the RAM powered on so it can boot faster but you also retain all the errors in memory you might be trying to flush out.

    There are several older HTC devices that it is just common knowledge to keep Fastboot off. It has been improved so it functions alot better now but there are still times you have to disable it to get a full reboot. Its a common power cycle process that their support service will ask you to do before returning for service.

    There are very few if any non-HTC apps that support Fastboot.

    Keeping the Ram powered on would only apply to restarts. If you power the phone off, the Ram isn't going to be kept on.

    With Fastboot enabled yes it does keep the RAM powered on. This has already been tested tirelessly on XDA.

    Well, I know this. With fastboot on, my phone booted in 18.65 seconds and I had full control of everything, including my widgets. With fastboot off, the phone took 48.12 seconds to boot to the point where I could unlock it, and the widgets didn't full load until the 1:13.45 mark. So it does make big a difference, makes sense that it would be due to the ram being cleared out on a "slow boot". I just wonder why the setting is in the "Power" section... does it save power to have it unchecked? I would assume so, since it would mean no power is being used to keep ram powered on.

    The power draw with Fastboot on and the device off is minimal to the tune of less than a 2% additional lose. It take so little power to maintain RAM.

    So, then many apps are being affected by fast boot, meaning it should have a good chance at fixing glitches. Your first statements was perhaps a bit too broad is all I'm saying.

    Here is where it gets complicated. An app can benefit from Fastboot without supporting it like widgets because the system elements handling the widget are saved through reboot.

    Basically Fastboot saves everything in RAM through reboot but Android only keeps what it needs to boot disregarding what is beyond that but doesn't flush the memory either.

    That makes sense. So, I'm gathering that normal boot is left as an option for completely flushing the RAM for situations in which it's necessary (glitches, etc)?

    Exactly Its great to use for fastbooting but always consider if your having a problem disabling it and rebooted might help and if you don't reboot much than it is not of much use for you.

    Wow. This thread sure got interesting! Thanks for all the discussion, guys. It's definitely WAY faster to leave the Fast Boot on. Hopefully I don't run into this phone bogging down anytime soon, and I won't have to worry about powering it down in order to speed things up. My Moto Razr Maxx got to the point where I was turning it on and off 3 times a day. I'll keep it on Fast Boot, but maybe completely power it down once a week to "flush" it out. Thanks again!

    The main con with FastBoot enabled is it drains your battery significantly more.

    I've never noticed this, I used it on my m7 all the time and now my m8 without any difference in battery life.

    It does make a difference. If you use it on your m7 and m8 all the time then how would you know? It isn't allot of extra battery use but it is more when having fast boot enabled

    Because I've tested with it on and off and using gsam the battery life is the same, for me at least.

    It's basically like putting your Windows PC to 'sleep' when you have Fastboot enabled.

    All fast boot does is keep the ram powered on when you shut the device off. That way when you turn it back on, it will start up faster. It doesn't do anything else.
