Chosen Solution
hi a customer recently brought a Samsung s6 water damaged in to see if we could do anything with it we have taken the phone apart and clean with isopropyl now the phone will start with charger cable in. says 95% battery charged but the problem is if we try to boot it will get to Samsung screen then turn off and reboot i took the battery off just to see if it was actually registering it and to my surprise the phone said it was charging and was at 95% with the battery not plug on steps taken 1 .disconnected charger port = no power from battery 2. tested with new battery = still no power 3. disconnected cameras = no power 4.plug charger port back = power says 95% charger boot no boot its not registering battery so not enough power to boot is my guess. i dont know if it could be related but the iPhones have IC chip problems when w/d batterys charging ect. any help would be Appreciated has the customer has photos that are valuable to her.
re flow or change U7105 IC your problem is solved :)
Check for corrosion around the the battery connector (on the motherboard) clean w/ 99% IPA, or perhaps ultrasonic cleaner, and if necessary, try reflowing connections in that area. I have several water damaged s6 motherboards that reboot like you describe, somewhere there is a harware issue but I can not track it down. However I have had some with corrosion around the battery connector on motherboard that I’ve been able to clean up and fully recover
i have a s6 edge and i it had water damage and i replaced my battery and the phone still wont turn on but when i plug a charger in it does but soon as take charger out phone cuts off but battery is 100%
im on same problem mine says 95 percent ive got it plugged in with a fast charger can get phone on soon as i unplugged it just cuts out but when off charging seems it working as now 97 percent battery but just wont use battery to turn on or stay on
Well mine also had a problem. Also water damaged. Connected to charger it says 100% but when turn on it is only 4%. Also when plugged in, it will reboot loop until it sbuts down voluntarily. Please help.
Hopefully someone can shed some life maybe ifixit can have my board for free and have a look see if they can fix it and reply with resolution as I’m getting a new board so won’t need this one
