How to kill power without removable battery? - OnePlus 3 Questions & Answers

Hi all, I'm thinking about buying the OP3. I've looked this up but haven't found a definitive answer and hope that someone with the device could clarify. How would I force-ably power down the device without a removable battery?
Reason I ask is because I like to fool around with clocks and voltages and those can often lock up phone when approach a bad setting. If a phone is no longer responding, is there any hardware level kill switch so to speak that will un-power the phone? Is this what the "20 second hold" on the power button will do? Does it work when phone is not responding? Thanks all.

Yes, holding the power button for some time (10, 20, 30 ... seconds) will kill the device, no matter what state it's in (working, not responding, in recovery ...).
That applies to all devices without removable batteries.

Fast click on power on

Hello,
I saw that the phone is switched off when I press the power button very quickly after a few seconds turns on. This for me is very annoying, if I have the phone in my pocket sometimes turns on probably because Touch inside the power button. It is possible to change to having to press for a few seconds and not for 1/10 second ?
it is not possible ?

Why is this a problem? The screen will auto switch off again in 15 seconds if still locked.
Becouse i want turn off the phone.
You want it totally switched off? Hold down the power button and a menu pops up on the screen, switch if off from there.
There is no way to stop the power button waking up the device when it is "standby", that's its purpose, I can't imagine anything more annoying than having to hold down the button just to check my phone
I don't see how you guys don't understand his question.
He says that it is annoying that when you turn the phone off (for X reason) and put it in your pocket, the fact that it only takes a slight touch of the power button to turn the phone on means it involuntarily turns itself on in his pocket. He wantsto know whether it is possible to make it so you have to press a long time on the power button in order to turn the power on, so that if the power buton is only pressed for a second, nothing happens.
I really wish people tried to actually read questions on forums.
This is an important question for all that travel by air.
to avoid that during the take off or the landing the desire turn on inadvertently
My problem was born in the cinema when I turned off the phone and put it in my pocket. After a few seconds I heard the sound of ignition, so I switched off again, then yet again ... up when I removed the sound, while other people looked at me in a mole ..
It would be nice if you could choose to press the button for 2-3 seconds before it turn on, to prevent accidental starting
Totally agree. I had the same issue on the plane the other day. I had powered it off but during take off it powered itself on in my pocket. I used to have an iPhone and it at least required you to hold the power button down for a few seconds before it turned on.

I really wish people took the time to actually read the reply and accept that sometimes when the OP is in broken english it is misses details, before jumping in to criticise others while contributing nothing of value to the thread.
If you reckoned it was easy to understand the question, why have you offered no actual answer or constructive advice?
If you assume that the question is... can I set the phone so that it requires a long-press of the power button to switch it on when it is completely powered off... the answer is... No, you can't. Perhaps there is scope for this in a modded firmware if you root the device. I suggest you email HTC support to suggest this an an enhancement in a future update to the phone.
Why don't you try this FlexiSheild Case Cover, I purchased one and it has a very robust construction flexible but not sloppy like the silicone ones.
I have found that to turn the phone on or from standby you have firmly press the on button you cannot turn it on by simply sweeping your finger over the button it also offers a lot of protection to the phone and has some rubbery coating on the back to stop the phone slipping out of your hand.
I believe this will elimenate your false switch on of the phone

[Q] Long press power turns on the phone?

I turn my phone off a lot when I travel to save power. I've noticed that only doing a quick press turns the phone off from a cold state which is very annoying when i'm just trying to make sure my phone is off like I did in the WM days and currently do with my android device. I'm wondering if this is restricted to my device (HTC 7 Pro) or it affects all WP7 phones.
Does this annoy anyone else? I've written to HTC so if it annoys you too please complain so we can get this changed!
My Focus requires a long press (2+ seconds) to turn the phone on. It sounds like your problem may be HTC-specific, or something is wrong with your particular phone.
Thanks for the head's up, my complaint has been forwarded to the dev department of HTC so hopefully they fix it soon.
my arrive turns in with a short press I think, as well as my tp2 and other HTC phones I've had. doesnt really seem like a big issue to be concerned over. the accidental turn off issue was resolved in the mango beta and powering off really isn't necessary just a switch to airplane mode or enabling battery saver.
Unless I misread the OP, his concern isn't with accidentally turning off the phone, but accidentally turning it on, since it seems that accidentally bumping the power button on an HTC phone will turn it on.

and I've told him that it's not necessary to do that in wp7. I don't get people, first they were complaining about the power button being too hard to press now it's the other way around.
l find that if you wanna check your phone..rather than pressing the power button press the camera button. If its on it'll go to the camera app. If its off it'll stay off.
I have never complained about the power button being too hard, I just checked and my TP2 does this too which is annoying. It's really not a difficult thing to implement and I should be able to conserve as much battery as possible without having to resort to flight mode only.
For now I'll use the camera button idea (thanks!) however ironically enough I have to long press the camera button to see if it wakes up, go figure...
Q&A is that way.... ---->

[Q] Disabling the power switch during lockscreen.

Hello everyone, I am new to this forum (obviously). So today I was robbed during my commute (I got my phone back). As we all know, the HTC One's battery is not easily removable, and installing a tracking service can help. Only problem is, the HTC One can be restarted, preventing any tracking software from tracking the phone's location. Disabling the HTC One's power button can be a solution to this problem. My questions are as follows: Is there a way to disable the power button, and if so how?
I apologize if this topic has been discussed before.

if you disable the power button you wont be able to wake the device. If your goal is to remove the power off and restart menu from long press power, this also wont stop anyone because you can power cycle the phone with power and volume held together.
I'm not trying to sell this app nor am i a dev but you could try https://play.google.com/store/apps/details?id=com.t3hh4xx0r.nfcsecure
it does cost money after a few days, but there is also a free trial. it works with NFC and takes over the lock screen so no matter what they do they cant get around this unless they have you NFC chip.( unless you have root and have a custom recovery that allows you to wipe data/data/) you can get NFC tags all over the internet including ones for your key ring or even an implant for your skin (weird? i know)
Security and anti theft options
Hmm well that's bad news for me.
What are the best security and anti theft software to add to my phone? I have

Hard reboot the device?

Hello forum,
I'm considering the One+3 as a substitute for my Galaxy Nexus device. Most of the reviews conclude that One+3 is a decent candidate for my needs (even though I'd miss FM radio as I did in Galaxy Nexus). There's one thing that worries me a bit. My Galaxy Nexus does become unresponsive (i.e. even not responding to power off button being pressed for many secs) from time to time and the only way to restart it is removing the battery. I'd guess that One+3/Android6 would suffer less from this kind of odd behavior but, hei!, there's no perfect hardware/software out there. So my question is, has the One+3 a way to do a hard reboot of the phone even if it does not answer to a long press on the power button?
Thank you
If it doesn't respond to a long press of the power button then you're out of luck. It does respond to a long press though. I've never in my 5+ years of android usage and troubleshooting seen a device that won't restart after a while (it can take up to a minute though).
Maybe pressing one minute the power button seemed to me a long time after being a bit mad with the device and I preferred removing temporarily the battery
Still, from your answer, I guess there's not button / way to do this hard reboot.
Thanks.
If everything else fails you just pop off the back and disconnect the battery lead...

How to fix an only sometimes working power button (which also easily triggers double click)?

So the power button of my Pixel 2 XL is unfortunately dying. Sometimes it works a few times and then a button press does nothing. It also triggers easily a double press (noticeable because that starts the camera) when tapping it only once. Gets really annoying when you think you have powered it off but it is still powered on in your pocket...
Are there any ideas how to fix the issue without opening the device? I don't want to open the device by myself after I ****ed up my Nexus 6 after a battery swap.
Any workarounds for the problem? Currently I use Novas remapping of the home button for power off but that is not really comfortable because you have to leave the current app for that.
Different roms have different options that may partly help. Often they are at settings/system/gestures.
For wake, use fingerprint. For sleep, set a very short timeout, or see if you can find a rom with double-tap to sleep option. If camera starts at the wrong time, disable the camera quick start.
But none of this will help you if the phone is really turned off. Can you really live with not knowing whether you can start the phone if it runs out of power?
I will look into some of the options. I'd like to stay with the stock rom though (but I have root if that helps).
The button is not that broken. If I press really hard I can always get it to work again, so I have no fear it won't power on again.
