How To Repair Charging Problem In Iphone 5s
My cousin brought me a white Iphone 5s for repair. It has charging issues. When fully charged, the percentage of the battery power goes down fast. During charging, the charging percentage does not increase gradually but jumps up really fast. That is an indication of a bad charging integrated circuit.
To get inside the phone, you need to take out two very tiny screws. The screen is pressed on that Iphone housing and with a sharp knife carefully pullout the screen.
Once you get inside the phone you need to get the board and the screen out. Again, these screws are very tiny and different sizes. You need to keep track of these screws otherwise you will end up damaging the board. Here is my organizing tool.
It is a piece of magnet glued to the table. Every screw that comes out of the board, I put on this magnet sheet in the order of the actual screws hole on the board.
This is the actual board of Iphone 5s. It has very tiny components on it. In order for you to see these components, you need this microscope to actually see the parts and work on it.
This magnifies up to x45 and if you have different lenses on it, it will go up to x70 which becomes an excellent tool for viewing these components and actually fixing them.
I am also using ZXW schematics files that you can get on line and you can actually view the parts on the board and where every component is located. With that tool and my humble experience, I located the bad part and with heat re flow machine I was able to take off the board. Before you get that part, I had to take a heat shield off and then to get to that part.
Once the shield is off, I could see the part and I marked that with a red square as you can see.
It is very tricky to put a new chip there since the IC place is not marked. I have wasted too many IC’s just to get it right finally. The part number of this IC is 1610A1. It takes a lot of practice and patients which sometimes I might not have. Anyway, the parts are found on line as well. Every piece cost about 5 dollars each. They are very tiny though. Check out the photo.
There are ten IC’s in this strip. That is how tiny they are.
After installing the new chip, put the board back in its housing, the phone came on and worked just fine. I tested the voltage increase and decrease and it was fine.
There are lots of video on YouTube that explain this whole process in more detailed fashion. You can check it out and learn from them if you are interested in such repair.
That is all the parts inside in this phone. Customer happy and mission accomplished.

Hihai: what iphone are you talking about? does the charger work on a different iphone? try to open it and check for voltages near the battery if no voltage there, replace the charging port inside the phone and recheck. it could be a bad battery as well.

Hi Waleed,
Thank you for your answer !
I have Iphone 5, when i change the charger it works. The problem is the charger itself. I checked the voltage and is ok, there is an eeprom that i think , which is corupted. I searched on internet to find more information about it, but nothing.

Great repair Waleed! These components are too tiny for my taste. A stereo microscope is something I won't be using either because I get migraines when looking through those. I rather use an USB microscope that also makes it easily possible to take snaphots of what we see right away. I understand you had some trouble yourself to replace the 1610A1 chip in one go, which is totally understandable?

Albert. the microscope that I have has a camera option built in. you could connected it to a big screen and watch it from there. yet is was hard doing the first time but once you get used to it, it is a walk in the park.

Good job, Waleed. How did you know which IC was bad? I couldn't find anything on that part# 1610A1. I don't think that's the complete part#.

Robert: the parts of the iphone ic part number not included in the normal book for the IC's. it is a complete part number. you could find them on ebay although I do not recommend buying from there. I looked everywhere to find the part specifications to that part, I could not find. if you are looking to buy some of these ic's. the web site is: microsolderingsupply.com. they are all the parts needed for iphone repair and it is located in New York

Thanks for the website, Waleed. I don't normally buy IC's from companies that don't provide datasheets, but I guess I would if I had to. It's hard to believe that the full part number wasn't at least on the package the IC came in.

Using magnetic mat and placing screws in the exact position, is something new that I learnt from you! This service is beyond me! So, I really appreciate your 'great' work on a 'Tony' circuit.Hat's off!

Prakash: you could check the charger or use another charger...it could be the battery if not, then it might be the charging ic or the charging port. I do not have the schematic for it otherwise I would have send it to you.
