I really enjoyed watching you work on a practical hack from your obviously strong knowledge of the electronics involved and an instinct for what might work in scrounging from available parts. Very resourceful!

Thanks for creating this type of content. After watching I was able to charge a dead phone battery enough to get it functional again. It took weeks to get a replacement charging port for a already dead Asus phone and it drained below the threshold to function normally. Now everything is good. Instantly subscribed to learn more.

I waited for you to get off the phone no skip is how much you have this attention bro!! Great video

Nice Job I used this method but in different way rather than used diode and resistor i used regulator thank u for this video

Hello Mr. Sorin, i think you can change in the OS power settings that you can switch Type-C’s output, choosing whether to receive power or send power.

Happy I found this channel. Ready to learn 🤓

got mine charging by slowly putting pressure/bending the charging cord/outlet. but that's temporary. (It would say charging temporarily, but not actually charging. It's charging slow now, while turned off at least it's charging.)ni can't do anything on the "board" so ordered a microcharger. that was good information, thanks.

You always give us a wonderful lesson! 🙏

Thanks 😊 🙏 alot sir, this video has given me guide on how I can work on China children tab...

This would make sense if the micro USB charging circuit was faulty but in this case why not just use a jumper wire from the +5V USB C to the micro USB

Hello Sorin, what about when the battery is full, this will continue to send 900ma, won't it explode? There is no sensor to stop the current when the battery is full?

Does it matter that you only soldered to one of the red wire pins? Does the battery IC feed the power evenly between the cells or is that the job of the charging IC? Also do you have to advise the customer to not leave it charging overnight? I'm just wondering where the cutoff happens for the power when it gets to 100% to prevent overcharging/overheating.

@Awynn0

No propper voltage cutoff, even with diode dropping the voltage, if left on charge battery could easily reach 4.4+ volts if the battery protection circuit fails of is set a bit high which will cause battery damage and at best early failure, at worst a lipo fire. That's why he keeps saying it's ”dodgy"

If you from UK how can I come to see you? I left my tablet in the repair shop and they for 3 weeks couldn't do anything about it. When you put tablet on charge, it shows -1%

Real fan of your videos! Do you actually need a diode here? could resistor be not enough?

@seckinseckin3919

resistor for decreasing current (watt) , diode for decreasing voltage

Good teacher

Couldn't you jumper the 5v from the USB-C to the 5v of the micro-USB? You would then be able to charge from either port and have it go through the built-in charging circuitry.

What device and software do you use for reading and displaying all those measurements on screen?

Amazing hack. Thanks. Is the USB C port still usable? Its in loop with the battery and the "charging system" will draw 900mA from USB C bus. Will it still work?

nice work

Great job thanks

Great video

Thanks!

that tablet will show like 100% charg when its turned on and plugged in even tho the battery it's not 100% charged coz the tabled will recognize the + taken from charging port as battery current ? 😬

He said it's a bypass circuit in the case of failed charging IC. So your answer is yes :)

does the 5V from the charger go to both the power ic, and the charging ic because the power ic needs a source of voltage to make it into many smaller voltages? thanks for comments...

@Infiniti25

The USB-C port on that particular tablet was not designed to handle charging so there is no USB-C charing IC on that board. He did however take the 5V from the USB-C power rail from a resistor or capacitor then he fed it into the resistor, then diode and finally to a battery pin.

He is bypassing the charging IC and so he is stealing 5V from the area around the known good USB-C port, looked like he took it from a resistor or a capacitor near the USB-C IC then he fed it into the resistor, then diode and finally to a battery pin.

Dont worry about the charging mistake on USB C, I had a xoom tablet, wouldnt charge through the micro usb. Took it apart, tried fault finding. Spent hours. Decided to read up on it and Xooms dont use usb to charge! They have a 12v jack socket. Nearly cried!!!!!!!!!

Hahah video start I was like ok he is sleeping on the job 😂😂😂 that's funny good video 👍

Just a question, if after putting an 1.2 ohm resistor and a diode straight from the 5.1 volts presents in the USB pin to the plus pin of the battery connector it is only taking 200mA, may the battery be faulty? (It is a 3.8 volts battery) I ran into this problem with a Lenovo tablet and after doing this dodgy repair the tablet does charge but at very low current rate so I wondered if the battery is just bad (I mean it looks like a battery with a high internal resistance which is a bad signal I guess).

be careful with the diode because some of them have voltage drop 0.2V

best. waiting for new things

What a show!!! :-)

how i fix a dell tablet no charging

Tnx for howto, really work. What Are You Smoking?

This Video Should Be Titled "HOW TO BURN A CUSTOMER'S HOUSE DOWN"!!!!!! Sorin - i love your vids and i've learned a lot - but this is dangerous! There's no way to terminate charging once the battery is full. Older technology , such as Nicads or nickel metal hydride cells - fine, once charged, they can handle a reasonably small trickle charge. However, once lithium cells reach 4.2 volts, 4.3V ABSOLUTELY MAXIMUM! charging MUST stop as you start plating metallic lithium onto the electrodes of the cell - leading to a short circuit and fire/explosion! check out battery university website to prove im not being over dramatic! - but you are dicing with death here. Look at Samsung, if they can't get the charging process right - how can you expect to get away with this! I'm sorry but this is stupidity and a man of your skill set should know this! If the battery is old and its internal resistance is quite high - this method could see the terminal voltage reach 4.4volts. ANYONE WATCHING THIS, I BEG YOU NOT TO TRY IT - IT WORKS FOR A WHILE BUT YOU HAVE JUST CONSTRUCTED A TIME BOMB!!!!

Hi, Mr. Sorin, you're doing a great job. Your videos really helps me whenever I have a challenge at work. Thank you very much. I was thinking if I could get any means of contacting you (email or any means) please

To limit current as i understood. But since the charger connector has an IC that controls the output current, if you connect both ports, it would be the same. No? I say this because 5V will be present on the charger IC. Please explain, maybe i didn't get it all together. Thanks

Yes, but if you connect a resistor from the output to the middle pin, then connect the middle pin to the battery +, it will be a constant current regulator :-). 5v/resistor = current passing. simple series circuit, im sure you know it. Can use a lm317 1.25v reg :-D
