iPhone 6 not showing any current, only show voltage

Hi I got an IPhone 6 sent in to me for repair regarding charging issue. This phone has no water damaged history. When charging the ammeter showing 0.01 - 0.02 (current), then I probe the battery connector while charging, my multimeter showing normal voltage (3.5v - 4.2v)

Okay let me straight forward, I’ve changed Charging Port, Battery, Tristar, Tigris and also i already checked the FL2511 it showing good sign. PP_5v0_USB also normal. PP_Tristar_Pin shows normal too

So what should I do next ?

Hello Azim. Is the phone booting properly with a know good battery or DCPS?

You’ve already done quite a few replacements under the assumption that this was a charging problem. However if the phone is not booting, a low current consumption can be caused by several issues. If the phone is only drawing 0.02A, then the boot sequence has failed almost immediately and it’s likely not a charging problem.

You’ll need to take a more analytical approach and test the primary voltage rails and then check what the PMIC is outputting (look for shorted lines) and then work your way toward I2C lines and RESET signals.

Yes the phone is booting properly but after a few minutes the phone reboot itself. When i double check the tristar, im using 1610A1 instead of 1610A2/1610A3. I believe that the A1 chip is for iphone 5s and not compatible for IP6 (Correct me if Im wrong)

You should use a 1610A2 or A3 for the iPhone 6.

From your statement “Phone keeps rebooting” Does it reboot when booting with a known good charged battery? If so, then you have a gas gauge problem which points to battery or tigirs. If it only reboots on DCPS, then that is because DCPS does not provide gas gauge and that is normal.


In a never been opened iPhone 6 that consumes no charging current but does boot, this is going to be tristar or tristar AND tigris. If you changed tristar and then tested, and the fault was actually bad tigris—-sometimes a bad tigris can kill a new tristar. Change them both again, but this time probe around tigris and make sure that you don’t have a short on any of its lines.

The tristar that i changed is 1610A1. I believe that the A1 chip is for iphone 5s and not compatible for IP6 (Correct me if Im wrong). So maybe the issue came from A1 chip

I doubt that---I use only 610A3b for all 1610 chips and that will work in any of them. I'd be surprised if one 1610 chip couldn't swap for any other 1610 chip.

I’ve also encountered this problem

When I turned on the device with a full battery, it indicated a 1% battery

I did the following steps, the problem was solved

1 - check for stuck battery pins. Sometimes they wear out and stop working properly

2- check for corrosion in the line between bsi and tigris

But keep in mind that this method only works if the iphone keeps rebooting when plugged in without battery
