@refectio i have an issue with this iphone 6. when i got it, it wouldnt boot. on dc and charger with battery disconnected it took around 0.23 amps. i removed tristar and tried dc again and got apple logo. put a new tristar on and as soon as the amps reach around 0.83 the phone restarts. it now eventually boots to the home screen after a few minutes but it wont charge, not showing the lighting symbol in the battery and it stays at 1%. i have already changed tigris aswell, tried a different cable, battery and port. do you have any ideas
Hey Daniel. Did this phone just die out of the blue (the famous nightstand issue ;>) or was it dropped or came into contact with liquid? You should probe around the charge circuit again looking for any anomalies. Specifically, check the SWI line (battery) and C1402/L1401 in the Tigris area. However, the fact that the phone takes a while to boot could be an indication that there is another issue at play here. Seeing as how you have already changed pretty much everything in the charge circuit, I would check out the PMIC and BBPMU outputs to see if another subsystem is causing any issues to the boot process.
Good news and bad news Bad news i only have the answer to 1 of your problems. and that problem is the battery problem. My sister has this problem. All you need to do is change the battery
@refectio Hi, i have a similar problem with an iphone 6. I have a question for you. What do you mean by “check c1402 and l1401” ? I have 4.38v on one side of that coil and 3.88 on the other side. Please help me because I don’t know what do try anymore. Already replaced tigris, tristar, checked all the voltages nearby and they all seem fine.
