Greetings, I have a fear that I could have defined the question in the wrong hub - I apologize if this is so.

Such a problem: the battery has run out of smart at zero. If connected to charging - zero reaction. I heard that in phones with a low charge, the ability to recharge it is blocked (sorry for the pun) - is this true?

I tried to plug the middle contact of the acc with a piece of paper and connect the charging - the body woke up. Turned it out of harm's way.

Standard adapter:
Frequency: 50/60Hz 0.35A Output: 5V --- 2A

And there is this one:
Frequency: 50/60Hz 0.15A Output: 5V --- 0.7A

Will the battery not be covered if it is recharged with a second adapter?

In the worst case, your electronics on the battery died, these are often "chip", then into the furnace ... If it is without electronics, then feel free to charge it with whatever you want, the batteries are very good. living beings. that's why there are two wires from charging to the terminals and that's all ... let it stand for an hour, and then it will recharge in the mobile, if it was only a complete discharge ...

Are you sure it's not charging? When charging a heavily drained battery, my Nokia also does not show anything, but it charges and after about 15 minutes a battery slider appears on the screen.

I also heard an option somewhere: heat the battery a little ... It seems like a little more charge and the electronics will charge the battery.

Usually, the nominal voltage of the battery is 3.7V, I “reanimated” these by simply connecting (observing the polarity) to the adjustable power supply, and gradually increasing the voltage so that the current is no more than 1/10 of the capacity (you never know what electronics are inside).
If there is only 5v, then you can turn it on through a resistor ~ 100-200 ohm for a while (check on the phone until it turns on).
But this all applies to a normal battery, just discharged below the threshold for the protection of the phone's battery from overdischarge.
