You are probably missing FL11, aka FL2400 in the SE —and definitely missing two of the caps. The picture is clear for the two caps, and less clear at FL2400.
If the symptoms that this phone are having are a match for missing gas gauge filter, then you know that FL2400 is not on the board.
Gas gauge problems in SE:
With a charged battery phone will reboot every 3 minutes
Battery percentage reported wrong—will say 1% or 100% or jump up and down erratically
3utools software does not “see” the battery percentage in battery details.
With a dead battery, the low battery “plug me in” logic will not engage, the phone will try to boot instead and show apple logo then loop.
usb ammeter will show low charging current, less than 0.5A
If those are the symptoms, then yes—-send this phone out for SE “little peckers replacement”
I see that you contacted me on iPad Rehab Microsoldering website, but I’m answering here to help anyone else with a similar problem in the future figure out if they have a little pecker problem ;0
