I've had my Droid 4 completely lose battery on one or two occasions where I wasn't paying attention to it while doing something else.
It turns out that I have to plug it in and wait until the battery is at 100% to get it to start up again. What is the way around this? Just holding the power button turns the phone on, shows the motorola boot logo, and then shows the battery at whatever percentage it's currently charged to. How do I bypass this and start into the ROM and then just charge from there?
In an emergency when I'm waiting for a call or something, this is something I need to be able to do.

The power button on my phone is completely non-functional, so I have to plug it into a charger to "kick-start" it on the rare occasion that it's completely shut off; which, more often than not, is when my now rapidly-aging battery craps out and I don't catch it in time. So I face this every now and then.
The solution:
Let the phone charge enough to safely boot; 10% oughtta do it. It seems that the phone does charge whenever power is being supplied regardless of its state, but the amount of drain while booting means your charger by itself probably won't keep up
Unplug the phone; this should make it shut off
While holding Vol+ and Vol-, plug the phone back in (you may be able to use the power button instead of plugging in, but I wouldn't know). This will bring up the menu of which the name escapes me at the moment
Unplug the phone (may or may not actually be necessary for success, but I always do)
Select Recovery (Vol- navigates, Vol+ selects); this will get you into the 96% useless stock recovery
Press Vol+ and Vol- together until the menu comes up; this might take several tries because either the phone is fidgety or the timing is stupid-precise
Select Reboot (either Enter or Ok on the keyboard to select, I forget)
The phone should reboot properly, skipping the forced charging thing. You can (and should) plug the charger back in anytime after you hit Safestrap/the post-SS kexec buzz if you have the custom SS installed which disables the popup at boot.

Yes... this is the method I remember using once, but I couldn't get passed the useless stock recovery this time around so I thought maybe I was just dreaming. I guess my timing was just bad this go around.
Thanks again, Septfox!
My DROID 4 is like my DROID 3. When the battery completely dies, you cannot press the power button while it's plugged in.
So, Dead phone. Plug it into the charger. Wait a couple minutes, so it gets some charge. Unplug the charger, Hit the POWER button, then plug it back in.
It won't work if it's plugged in, dead, and charging. You gotta unplug it to turn it on, then plug it back in to continue charging.
That is happening not only with this model phone. On other brands is the same.

I have a brand new Nexus One bought on last year April. For some reason it wasn't to be used. Yesterday, I got it out of the package and charged it for ready to be powered on. Unfortunately, it reacted nothing as I pressed the power button! I took out the battery and put it into other Nexus One, it showed the battery was 100% charged.
I took back the battery and repacked it to this new Nexus One. I tried to press the power button more and more with data cable connected pc. Nothing happened. Just one time, the sceen lighted on and the "X" in four colors appeared! I didn't know why it was powered on. Maybe I pressed the trackball or volume up/down buttons, God know it.
The X sceen lasted almost for ten minutes and then sceen was off! Yes. It shutdown! I can't power it on anymore!
It seemed the hardware was OK. It may be the locked by the outdate android system. The android prestored in this phone is version 2.1.
Any advice is welcome. Thanks.
Can u you go in fastboot? Press power button+trackball..if so then you can recover your phone by unlocking bootloader and falshing custom recovery.
Sadly, It can't be power on and go in fastboot by pressing trackball+power button.
Any more advice?
Check the battery terminals just to make sure they're not dirty.. Sadly, you MUST be able to at least be able to boot something (hboot/fastboot) in order to troubleshoot anything software related. Sounds like you've got a hardware issue that could be one of (literally) a million things.
Sell it on EBay for parts. You can probably get $50-$60
you could try pressing pwr/vol-/trackball all at same time, hold down for around 30 seconds to make sure
commonly known as 3 finger salute
try power on without sdcard by manual methods and plugging in and plugging in with no battery
I have seen a video on YouTube on how to fix the power button which is known for messing up and how to turn it on. Search YouTube
Sent from my Nexus One using XDA App
is it that the power button is not working? that would be weird for a new phone though.
have you tried to turn it on using the "jump start" method?
connect the cable. led the charging led come on. remove the battery, wait for the led to go off (while cable is still connected) then pop the battery back in.
see if you can get it to start that way
When you plug charger cable in your Nexus, does the orange or green LED go on?
If one of them does and stays (green for full battery, orange otherwise) - then your problem is most likely the power button. It may not be the only problem, but at least the one that's stopping you from turning on your phone. You can try "jumpstarting" it by inserting battery while charger is connected.
If you don't see LEDs when plugged in - your phone is done.
If you see blinking LEDs - battery terminals might need cleaning/fixing, it usually happens when the battery is out of the phone.
Hello. This morning I've turned off the alarm, turned on WIFI and went back to sleep. I can't tell for sure, but I think the battery was low. During the next 2 hours I checked the time several times. I don't remember accepting any OTA. Eventually I got up, tried to check the time and the phone was off. I tried to turn it on, no effect. No matter how many times and for how long I pressed and held the power button, the green LED only flashed for a split second and that's all. I plugged in the charger, and the LED stayed lit -but- there was this barely noticeable flickering. Charged it for about 30, 60, 120 minutes, didn't start plugged or unplugged. I went to work, 8 hours later (phone was unplugged) I tried to turn it on again, this time the LED doesn't even flash, but when charging there is no flickering. No combination of buttons works. Windows doesn't find the device, neither does RSD.
I've never done anything 'custom' to the phone. The last change I made was setting the alarm to turn off by shaking (yesterday, never used this option before).
Is it dead?
Try taking SD card out and holding Vol down and then Power for 20 secs, then let go of Power,
Already done that, nothing. No matter how long I charge it now, after unplugging and pressing power button the LED doesn't even flash. Could it be a battery problem (before its death, it would last for a day)? Is there any way of recovering my data without buying a new one?
Try opening and disconnect battery for a bit.
I'll do that as a last resort, on weekend maybe since I don't have the tools with me. Any other clues?
Nobody knows how to help me?
I'm going to make a factory cable. Will this alone allow me to recover the data? Or if I'll be able to flash the phone, can I recover the data afterwards?
Also, I'm not sure if I understand correctly: does the factory cable recharge the battery or not? Is there a way to recharge it when removed from the phone?
Try to use medfield unbrick script. If You have only green led it seems to be bootloader error so this script should bring Your phone to life or Your phone has broken emmc and You can start looking for a new logic board. Good luck.
I've installed the drivers, but Windows and XFSTK don't recognize my device at all. Factory cable also didn't help. I liked my phone very much. :angel:
Did You enter medfield mode using combination with camera button??
By a combination you mean holding the camera button and connecting the phone to a pc? I tried that.
Disassembe Your phone, pull out battery, push power button for a 10 sec, plug in battery, push camera button and connect USB. If it wont help You I don't see any hope for Your phone.
Well, new option to try is a new hope. I'll try that on the weekend. Could you please be more specific:
1. Pull out the battery.
2. Press the power button and wait 10 seconds.
3. Insert the battery: should I be still holding the power button at this moment?
4. Press the camera button.
5. Plug in the usb cable (factory? regular?) - should I be still holding the power and camera buttons?
Battery trick is only to discharge capacitors. Sometimes even phone is dead it can turn on in some strange mode and then You can't boot it to flash. Thats why You need to pull out battery, push power for a few sec to completely discharge motherboard and just release this button. After that You can just plug in battery and continue normal unbrick process - so hold camera button only and connect regular usb cable.
You can also try reset option instead of pulling battery out. To do that do not disassemble Your phone but just plug in regular USB, when phone starts (green led) hold power and vol- until green led goes off and then quickly start holding only camera button.
I have no more ideas.
Ok, I've tried everything. Nothing brought my phone back to life.
Thanks for all your help.
Hi all,
plugged my phone in overnight to charge as usual. Woke up this morning and it was off. I presumed it hadn't charged properly so plugged it into multiple other chargers/battery packs etc. and nothing is happening.
I have it plugged in right now and it's just all black and the charging light isn't even on.
If I press the power button, the charging light comes on, stays on for a few seconds then goes off.
If I press and hold the power button then nothing. If I press and hold the power+UP nothing happens, if I press and hold the power+DOWN nothing happens at all.
My 'guess' is that the battery is so knackered (3yr old phone) that it's depletion overnight just emptied the battery so much that it just wont recover now and take any charge.
Looking for any and all suggestions of things I can try.
Hold power, volup, and voldown simultaneously.
Try connect it to computer, boot in flash mode and flash FW via FlashTool. Possible is that the FW got messed up... everything is possible.
Managed to get it going finally. Wouldn't charge, didn't anything. Plugged it into PC, loaded flashtool and it recognised it. Nothing happened though so was talking to tech support and magically after like half an hour talking to them it suddenly booted with 1% battery life.
It'd now charged and running ok

Stuck on "please lock bootloader" screen when plugging in after depleting the battery
No button inputs work. The only solution seems to be waiting until the battery fully runs out and plugging it in again, after which it sometimes boots up. At least I got it to the first time, it failed just now. Maybe I need to hold some button combination while doing so?
How do I fix this properly? And what's a sure way to get it to boot from this? I'm already wasting half and hour on a minute's charge, God forbid I ever forget about it plugged in for longer. Would have to throw it in the drawer for a couple days and probably end up with some permanent burn-in too.
I haven't seen the screen in ages but doesn't it tell you to press the power button to acknowledge the unlocked bootloader? Also from memory it tells you it will automatically continue but it never does.
What seems to have done the trick is holding power&volume+ (probably just power is enough), so it loops through the 'empty battery' splash screen at least once. I think that's how I did it the first time too.

It never seemed to make any difference whether I pressed the power button or not, in fact it always booted up automatically after some time, this scenario excluded.
I suppose my problem might lie in the fact that buttons aren't working on that screen for whatever reason? Rather than it not going away automatically after battery depletion.
It is a bug in the bootloader. You can get out of the screen by disconnecting (!) the cable, and then holding all three buttons for multiple minutes until the device forcefully shuts down.
Before you do that, leave the phone plugged in for 10 minutes or so, so it can charge the battery to some extend. Then start the phone without (!) the cable plugged in, and wait until it boots into Android. When it is booted, you can safely plug in the cable and let it charge to 100%.
Just make sure you leave it for some minutes so it has enough charge to boot through the bootloader and start Android.

i had a similar problem after a failed attempt to boot into recovery.
for me the following did do the trick and booted my phone back into system:
- deplete battery completely
- plug in charger and keep power button pressed until phone is charged enough to attempt boot
- keep the power button pressed until nokia logo appears

How long is "multiple minutes"? I tried holding all three buttons at first, but gave up after probably a minute of nothing happening. I'll keep that in mind though.
Is there any hope for this to be fixed in the future?

Well, multiple definitly isn't one I haven't stopped the time yet, but expect waiting and pressing them for around 2 to 3 minutes, maybe even 5. It might sound stupid, but it will work.
About fixing it, I don't know. It might be a bug in the reference bootloader that Qualcomm provides for Snapdragon 835 chipsets, and I doubt that FIH / HMD have the resources to debug and fix that.
I get this same screen while the phone's powered off + charging and it's annoying.
I was going to start a thread to ask whether it's possible to charge this phone while it's turned off (without the screen being kept on) after unlocking the bootloader. I guess based on the posts in this thread, that's not possible? [emoji2357]

No, I guess it isn't. I've tried to plug it in while it's off and turn off as it's charging and in either case it resulted in the phone hanging up on that screen. I can confirm though that holding all three buttons for a while does turn it off and allow me to boot normally which is cool.
But is that possible with a locked bootloader anyway? Or does it always power on? I can't tell if I ever needed it to charge like that.
I see this "warning" message only on android pie builds, it doesn't seem on oreo builds. I think problem seems that kernel dependent (oreo is on 4.4.78 and pie is on 4.4.153). There is one way to get rid of that message, as @THMSP said, holding all 3 buttons pressed during 2-3 minutes and let it to be shuted down. Then, let the device to boot normally and plug in. Finally you shouldn't connect to charger when it's turned off on any pie build.

Locked bootloader
It was powered off for some time because I had to replace broken display
Now when I try to boot a battery icon appears and then it turns off. Same thing happen when I plug in the charger
I repair smartphones professionally so I am sure no hardware damage during the repair

I went through it. try holding the power button, connect the cable and only release after the battery shows 1%. you can try holding the power and volume + or power and volume - buttons too instead of Power button only, in the same way. alternatively, you can leave it on the charger for hours and it might turn on. Make sure you are using the supplied xiaomi charger
If I plug the cable or I plug and hold the power button the phone just tries to boot continuously showing the battery icon and then turning off and repeat, nothing really happens
Is that what is supposed to happen?

Yes, It happens. Luckily the phone will reach 1% and charge normally, keep trying
You actually saved me, it worked in the end, after some loops it booted alone, all I had to do was just let it sit there, didn't even have to keep power button all the time, once it started the loop I just left it there and when I came back it was booted.
