- Hello guys, I am attempting to built a charging/dissch
arging/testing system for iPhone batteries. Because I have a lot of age...
- yes, you can put the "invert colors" function for better readability on the triple home button click. but then the display would be completely inverted. since only a part of your screen is inverted it is definitely a broken lcd.
- i don't think it will happen again. It's not your fault! Chances are your iphone 4 battery already had a few hundred cycles on it. you should get an iphone 4 put a jailbreak on it and use "batteryinfo" to read out the number of cycles before you place the "new" battery into a customers iphone....
- hello there. I agree with iwillfix. I found that original lcd (the one with the black stripes left and right only have this problem extremely seldom.. but the copy/half original LCD on the cheaper displays have this problem much more often. a burn-in of about 15 minutes to several hours will fix this problem most of the time. Since we offer to repair the displays within 30 minutes for our customers.. i tend to buy the original lcd displays... but i tested a new supplier who said it is original but it is not.. ugh... so i have to write a formal paper now to inform my customers about this burn in procedure...
- I finally fixed it(.com) haha ;) Turns out this was a no-brainer... I better should delete the picture I took before someone else notices it. Solution: To read the voltage I connect my multimeter to PIN 1 and 4. So why on earth did I try to connect the charger to PIN 1 and 2?! So embarrassed...
- The nut is without purpose IMHO. In every 3rd iPhone of my customers that nut is separated from the logic boards and their wifi is fine. In my opinion it is a predetermined breaking point. If the iPhone fell down it will easily break off. I guess when it is missing, Apple Technician can tell that somebody tampered with the iPhone already. So if you are fixing an iPhone for a customer who still is under warranty, better put it inside there again after you are done. Just hold the nut with a tweezer while you tighten the screw.
- It can do both. You also can program your own charging/discha
rging programs. Like discharge at 300mah until empty then charge at 1000mah until full. Then discharge at 800mah which would simulate heavy using like 3d gaming or gps navigation. It also can then transfer the discharge chart to the pc so you can see if the voltage dropped below a certain value which would make the iPhone shut down in real life. The situation right now is like this: The charger starts charging at 4,2V and 1000mah. (that is milliamps per hour, the same the official apple wall charger uses). But after about 25 seconds the charger says it's full... So am I doing something wrong? Will it work eventually with a hint of one of you? Please help! :D
- and don't forget to ACTIVATE your iPhone after a restore! Otherwise it tell you "no signal"... kept me busy for over 5 hours with mainboard and dock connector swapping... :(
- So it's 5 months later now, did the suggestion of michael work? I am eager to know how this story ended! ;)
