    You should be able to charge a phone when turned off and/or when battery has drained and turned off the phone. Just fast charge may not work when phone is off.

    So I guess a technique to bring a battery from near death is to charge wired as well as try to kick start it through the wireless coil. I'll have to remember that.

    i am very curious as to how you could possibly pair your 'dead phone' with the wireless charger???

    Maybe he means to make sure the phone is on correctly.

    My work wireless charger will not light up if the phones not on correct.
    My home wireless will flash the blue light if it senses it on the charger but not correctly, when "paired" it stays blue then shuts off (perfect for sleeping).

    A portable power bank will also provide the slow charge to bring it back to life? This is not my original post, but a paraphrase from a post down below. I tried it and it worked perfectly. I used my power bank charge unroll 3% , then I used a regular charger. Best of luck.

    hi all,

    i just had this problem earlier today. I had never had an issue with charging my few month old galaxy s8. Today i let it completely drain to 0%, it wasn't the first time though! I plugged it in and got a black screen with a lighning bolt in a circle. I tried a few different combinations of charging cords, wall adapters and outlets and got the same symbol a few times but the phone never seemed to charge. Then it stopped doing anything at all. I tried holding the power button down and holding the power and volume down buttons together. Nothing worked. Finally in a last ditch effort, i put my phone on my old "slow" charging wireless charger... Nothing happened. I then plugged in my fast charger cord at the same time and held down the power and volume down button and low and behold the safe boot option screen came up! I have no idea why it worked, but it did.
    this works. This worked instantly. God bless you!

    If you have a charging problem after going to 0% the best solution seems to be plugging in to a USB on the computer and also leave on a slow wireless charger if possible and just leave it until you have 5% or more, then you can go back to the adaptive/fast charger

    My Note 8 died overnight this weekend, while taking updates. Sunday morning I woke up to a dead phone, that would not charge. My buddy works for a company, who happens to refurb some of the phones AT&T take back. He told me the most common way they fix this issue when they come around, is to connect a wireless charger and once they are paired, connect the regular fast charger at the same time. I did this, and in about 30 seconds my phone had the lightning bolt on the display, and about 5 minutes later it was at 10%. Note the wireless charger I have, is one I used with my S6 Edge that I bought off Amazon for like 15 bucks...its not a fast charger, but it did the job for me.
    Thx for the update & the how to. I may just go get a wireless charger just for this eventuality.

    I bet you could have revived it by stack charging. Plug in for 30 seconds , and unplug for 30 seconds. Repeat for about 10 or 20 cycles. I have revived smart phones and tablets that have run to zero and wouldn't do anything a number of times. This process stacks enough of a charge for the phones charging management to take over.
    I bloody love you jhimmel. I tried everything to get mine to charge and nothing worked, but then I found this post and bingo; she powered up. Only took about 5 repeats of unplugging and plugging. Thank you!
    ETA: Mine's an S9+ btw but apparently the S9s are having the same issue when the battery runs down to 0%

    And all this could be eliminated if they used a charging chip that could do pre-charge. The ones that can and the ones that don't are about the same price, so all it would cost them is thought. I guess they ran out of that. (Back in the day, when you could remove the battery, I brought a lot of "dead" batteries back to life in an external charger that did pre-charge [and cost me less than $3].)

    I've had my phone since first shipment of pre-orders and haven't let it drain to 0 until last night just to check.

    It had gone down to 10% and figured I'll run a YouTube vid until it powers off. Completely discharged and then trying to power on to make sure not a drop of juice I plugged it in and until the red LED turned blue and powered with phone fully charged.

    Even though best practice is to keep battery in range of 45-80% I've also heard a full discharge to charge isn't too bad and also help in calibrating battery.

    I just came back from spending a week all over Switzerland and I should have checked before going to be safe... many a times you're out all day exploring the country and even if you try to make sure covered with battery packs you can still get close to running out of juice at the end of a long day and last thing you want is to be stuck in another country with a phone that wont charge after going zero with all your info on that phone. I gotten close to running empty that the idea of a dead phone from these posts did cross my mind and hoping I wouldn't be one of those unlucky few with most likely a defective battery if you experienced it.

    These phones are over a year old so out of warranty but honestly now I think it would have been better to test early on and if you had the issue then you would have been able to get the battery replaced under warranty or the phone if they deemed it needed.

    this is still a real problem, issue??

    This really works! Never heard of it before but your post explaining it shortly after this one makes a lot of sense. Thanks!

    I just took my old Note 2 out of the closet and brought it back to life as a Duo-only phone for my 3 year old grandson.
