iPhone 4 fell in water

iPhone 4 was in water for less than a minute. I dried it in rice for 48 hours and it was not working. When plugged in a battery shape with a few red lines appeared and it started up but continued searching for service and would not connect to wifi. After searching through this site I got the phone apart and removed the battery. Only the bottom water sensor was red. I left the battery out over night then cleaned it and the cell antenna with rubbing alcohol and put the phone back together. It was working fine for several days then it just shut down. Once plugged in it went back to how it was after during it out and changed the date. I tried repeating the steps I did before and it didn't work. I was wondering if anyone could tell me what to do. If there is anything that may need cleaned or replaced or if the phone is past fixing.

I also noticed in the short time that it will stay on that the screen is twitching and it changes the date and time to December 31 1969

battery replacement is a must after water damage---i.e order a new battery.

You still need to clean the logic board itself---it doesn't sound like you removed the logic board, took off the bottom EMI shields and scrubbed out any corrosion---this is also a must when you know there was water in the phone...otherwise corrosion will continue and the phone will grow new problems.

these are inexpensive things to do, i would recommend giving them a try and then if you still have a problem, then you may need to have someone look at your board---which may entirely still be repairable even if there is board damage.

i have to point out that you'd have the same result if you'd just left it out on the counter for 3 weeks. Your phone still has corrosion inside--every wet phone does. Those spots will continue to have more and more brittle solder connections since the phone was never cleaned. It is great that this phone is working right now---that is just due to chance. Keep in mind that this phone will be highly susceptible to drop damage and/or components getting knocked off the board with any subsequent repair.

You should use Silica gel instead of rice The rice thing is a myth

Silica gel is also a myth, it won't take away the minerals the water leaves behind either
