iPhone 5 randomly rebooting after water damage - GSM-Forum

I am no iPhone repair pro (I am an iOS developer), just trying to fix my wife's "almost running" iPhone 5.
I try to describe it in a whole, so you can point out what is the problem from your experience and how to fix it if possible. Thank you.

History:

she dropped the phone in the toilet, so it's been for a few seconds in "water"
then dried and turned off for about 4 hours
then she tried to turn it on, it went on, but rebooted in cycle on apple logo
she could not turn it off, so it stayed like that for few hours until I removed the battery
i took it apart (not much water inside, few drops visible on two places), washed in isopropyl, let dry for 2 days and turned on

Symptoms:

it seems to be running fine, only after some time it randomly reboots
screen turns black with stripes, and then apple logo
the time until the phone reboots depends on the time being turned off
if i leave it off for 2 days, it runs for 2 hours
if i leave it off for 1 hours, it runs for 5 minutes
if i don't leave it off, it will reboot just after 1 minute, then 20 seconds, then 5-10 secs boot loop
it seems that with battery charged to full (and charger connected?) it lasts longer, up to 1 day
on the touch it is not excessively hot, the battery is charging and the percentage is updating
one thing i know is not working is a compass, always shows 0° (gsm, lte, mic, speaker, both camera, screen, touch, gyro, accel, gps.. all seem working)

I already tried:

restore
cleaning again
remove/replace all parts around logic board from different iPhone 5 (no camera, no bottom board, other screen, other battery)
with or without charger connected
the phone is not jailbreaked so i don't know if there are any error reported in the logs (how to get the logs from iPhone while it is booting?)
