@Ludde1

Is there someting anyone would sugest trying first of all, like a new battery or a new screen, or is it most likely destryed completely by short circuit from rainwater?

Welcome to the forum.
Sadly you could have read up, and still can on what to do with a wet phone

For example:

FP3 Wet phone now battery doesn't charge

Hi there, my FP3 got wet the other day and now the battery won’t charge when plugged in. I’ve taken the phone apart and put it in rice to dry out. Any help? Should i get a new battery? A new bottom module?

BAD MOVE: Putting in rice

• First is too remove the display module and dry the phone in flowing air for 24 hours
• Clearly you should not be using the phone. If you think the battery has shorted it’s a fire hazard.
• You can check the battery voltage, you want a min of 3.8V
• The phone will not power on from just power input there has to be a battery

Once the display is removed check for red squares.

Rain water inside - what could be wrong?

Hi and welcome. Further to what @OldRoutard has said it can take days to dry well in a flow of air and ensure you dismantle the phone to get air around the modules and help dry the contacts. For the dampness indicators you will have to dismantle the phone to the point where you remove the screen and then see this post and two above it. hopefully you don’t see a red square. The top left in the top image is the red square in the bottom one. [image]

Clean all contacts and surfaces with Isopropyl alcohol if they are in any way tarnished

Fairphone 3+ does not power on

Yes sadly your problem form the start didn’t seem like a battery issue. Regarding the internal connections have you tried cleaning the earthing contacts between the display and core module. The ‘solder’ contacts outlined in red on the display. [display_module] For more mention of these contacts see, but they are outlined in blue in that topic

You may want to clean the charging port

FP3 Bottom & Top module breakdown

Hi. Images below taken with an FP3+ I have a defunct F3 that I disassembled to see if I could fix it; No luck; but whilst at it I thought I’d take a look at the bottom module as one issue was that it wouldn’t charge. The bottom module can be prised open, it has four small latches, two stainless steel and two plastic, so be careful. I opened the steel one first. Here is the inside of the two halves of the surround. Centre is the slot for the USB C port. The shiny B98CBC is probably the vibrato…

You will have no warranty so don’t worry about a deep dive into the modules.

The actual charging units are on the main core module, so check that is clean

The buttons are on a little strip that can also be cleaned.

If the above doesn’t produce any results you find a fairphone angel near you that can provide a more personal help whom may also have some spare modules yo can try.
