Man you are a genius. I feel smarter just watching your detailed and in depth analysis. The user was kind of hard on that phone though. 🤕She got the last mile of usage out of it...😉

[@thokokasiya6802]

Beautiful and smart work, I have learnt something out of it. Thanks for the video Sir.

Bravo i like the way you teach n explain atleast I have learnt something.

[@platinumphonesandcomputers]

thanks for appreciating

Hello, do you have more in depth troubleshoooting video about the smartphone charging system or basic phone motherboard troubleshooting about what might be wrong on the phone and where you commonly probe in the motherboard using the multimeter?

[@cmtechservice]

Great info thanks for sharing! The tiles for heat protection great inginuity.

Asante sana ndugu

[@mayaeidolon5623]

Thank you for this video. I've watched a couple videos like this and noticed that people seem to know what the correct voltages are supposed to be for each component before testing them with the multimeter. Are there certain keywords to search to find this kind of information online?

[@fayvixe9062]

hey ! your work are very cool !!

[@habtamusium8646]

lovely work ! many thanks .

[@platinumphonesandcomputers]

Thank you

Great video! Can you link where we can get that in line charge meter? Thx in adv.!

[@platinumphonesandcomputers]

Thank you, I will put it in the description soon

[@jupyterascending3429]

great video....can you let me know about the device you used for soldering

[@platinumphonesandcomputers]

Thank you, its a Gordak 868A SMD rework soldering station

[@babyyoda2219]

I have a Moto One Fusion. It's not drawing any current at all when plugged to charging. Is it more likely the motherboard or the charging port board?

[@AdukulegilbertGenius]

Where are you located in Kampala because I need to attain the training. Waiting for your reply. thanks

[@collinsomondi2749]

This is good work.

[@Felix-zq5qz]

Perfect,, I like that technique,, I'll you it at my workshoy$it only that I lack that small meter,,

[@platinumphonesandcomputers]

Yaa the small meter is called USB current meter, you can also download some app they somehow work the same

[@desirelungu7636]

Thanks alot. I wish if you can help me with samusang core prime display is showing everything but unresponce you teach very nice

[@platinumphonesandcomputers]

hello, thanks for writing me. If device displays images well but unresponsive to touch its most probably a fault sensor, replace it.

Great

[@TheJerbau]

Hello and thanks for the video, how did you get the phone to start ? I don't understand , thank you again ;)

He charged the battery using one of his tools

[@platinumphonesandcomputers]

I boosted the battery using a power supply

[@siddiquishoaib7929]

[@flordelynesamiano3613]

Good day! Question re xiaomi mi max2, battery specs is 3.85V but when i multitester the battery reading is 4.18V?

[@platinumphonesandcomputers]

Usually when phone batteries are full they read up to 4.4V, so 4.18V should be around 80%

[@JC-vi7gg]

On my iPhone 6 the when is charging the volts drop and I can see takes longer to charge any idea why

One problem you are doing is not using a nozzle with a small opening instead of placid load on the phone

[@waynegram8907]

PLATINUM PHONES, I'm very confused about how Fast Charging Chargers work because most cell phones use 5volts @ 1amp so if you use a 65watt charger it will doesn't charge most cell phones faster, any reasons why? All cell phones have a built in linear charger circuit which I'm not sure what the linear charger circuit is doing which I think is changing the Pulse Width of the current being charged into the battery. The Charging system circuit that is built internally inside the cell phones has to support fast charging? to be able to use a 65watt charger, any reasons why?

[@platinumphonesandcomputers]

Thanks, Gram for this question, Fast charging in phones is actually 2 way, the phone should support fast charging well as the charger and USB cable, The phone should have a switching charging system Ic which uses PWM with an external inductor so as to create different current by adjusting switching frequency. Then most phone fast chargers a rated up to 9V, 2A equivalent to 18watt, well as a normal charger a 5V 1A, a 65W chargers a usually for laptops. You should check if your phone supports fast charging and it's mostly in Type C phones only. Linear chargers use voltage and current drop methods, they do charge faster but produce a lot of heat, are not safe and efficient, they are mostly built-in cheap phones and Tablets.

[@waynegram8907]

@@platinumphonesandcomputers If your cell phone doesn't support fast charging that means the cell phone internal charging system IC is a LINEAR charging IC? I'm not sure what the part numbers are for the charging system IC chips or what circuits is inside the charging system IC chips. The theory of operation is the cell phone takes the 5vdc @1 amp and the charging system IC will convert the 5vdc@1amp to a PWM signal to "tickle charge" the battery? I don't know any other things that use those charging system IC chips other than cell phones and tablets but they have LINEAR and SWITCHING charging IC chips. The Type C cell phones is the USB-C cable type which charges the cell phone differently because the USB-C has some type of bi-directional for sensing Heat I think because the more WATTS the heat will adjust the PWM signal to tickle charge the battery. I'm not sure if you can REMOVE the linear charging system IC chip for cell phones that doesn't support fast charging and modify it by installing a Switching fast charging system IC chip? not sure if you have done this before or not these types of modifications to NON-fast charging cell phones to making them Fast charging cell phones.

[@Ilegator]

Hi, thank you for the video. I have a Samsung A40 which won't turn on or charge. I charged the battery manually just like you did, but when I try to measure voltage I get 0 volts. If the battery is dead, how come it draws amperage? Is that normal? Thank you again!

[@platinumphonesandcomputers]

hello, if the battery charges but you measure zero when connected to the motherboard, you probably have a short on the motherboard. Check out my latest video about fixing short motherboard

charrging 3.6 amps..... its 360mA or0.36A not 3.6 ?? no solder wick no dock test.... heat the board by chance..... dude.... remind me never to take a phone there..!! get in touch with me i can teach you some solid techniques!! and good study material. and for christ sake... dont heat the board from the bottom.... use a simple soldering iron to do the whole process!

[@victorsantos2354]

seriously send me msg i will be happy to share experience!
