When you see and exposed pcb circuit, try to gently lift it up. Step 1: Open the Iphone and Remove the Battery The pics of universal charger and the iphone are mine. Credits for the battery pics go to and Luke Hines from. I didn't have time to take pictures while doing so, and I don't wanna risk anything by opening it up again to show the connections. Who needs to follow this project? People like me who are PEEVED with iphone parts & repairing costs, and just want a working iphone and are ok with long charging times, without worrying about expensive IC's and capacitors. If I need the updated charge percentage, I need to reboot the phone. So while the charger is connected and phone is on, it will either show the same percentage or declining value, but not the increase. The iphone reports DECREASE in battery percentage when it's on, NOT THE INCREASE. (If you can buy such charger with 700-1000 mA ratings, you will get faster charging times, I don't need it so much so as to further search or buy one.) You can also buy expensive universal chargers with 1 amps ratings and led screen etc, but don't buy very cheap ones as that would be risky. So I concluded that (at least) this charger trickle charges the battery once it's full. There was no heating at all, the battery was cool to touch. I have even left it for charging overnight, the battery was fully charged, the charger's green led was lit solid. Even better, once the battery is 100% full, I start using the iphone with the charger still connected, I even turn on the personal hotspot with LTE data mode. I have to put the phone in airplane or 2G mode, then charge it. This charger provides 0.4 amps only, hence it takes a long time to charge if I am using the charger while using the iphone in LTE network. My project is working better than I expected. This universal charger is quite cheap, but of a good brand, it has a green LED indicator, it keeps blinking when the battery is charging and glows solid when it's fully charged. Now I HAVE AN IPHONE WITH ANDROID CHARGING PORT. Then I put an ANDROID CHARGING PORT in its place. I desoldered (or just pull it off) the iphone charging port to make space. I decided to buy a universal battery charger and join the wires directly to the battery terminals/tabs.įirst the wires from the battery terminals go to the charging port. Now you can't provide 5v directly to the battery, it needs around 4.2v for proper, risk-free charging. VOILA! The iphone started functioning as if nothing's out of order. Hence, I removed the pcb from a cheap spare battery and connected an android charger's (5v 1amp) +ve and -ve wires directly to the battery pcb THEN connected the pcb connectors on the motherboard. First I tried to provide current directly to the motherboard, but that doesn't work, the iphone needs battery data from the battery's pcb to start and function properly. Now I didn't like the idea of spending a fortune on that iphone, I decided to use it as a spare phone and to charge the battery directly. This was the first and last apple phone I ever bought. This iphone belonged to my mom and I got her a new Google PIXEL. It isn't my main phone, I HATE APPLE PRODUCTS. I knew that the problem was with the iphone motherboard, most likely the U2 IC and/or the tiny capacitors near the battery connector. I tried 2 seperate charging flex from IFIXIT, both of them got corrupt and stopped working. I have an iphone 5S, there is some problem with the motherboard due to which newly replaced charging flex/cable stops working and gets corrupt.
