My phone won't charge

A few days ago I dropped my phone in a toilet, it was in my back pocket and it was working for awhile, when I woke up the touch didn't work but the phone could still turn on, I left it in rice for a couple of days and it just started working a few hours ago but it wont charge. The battery bar at the top right blinks and a notification pops up that says “your phones temperature is too low. Charging will continue when the temperature returns to normal” and my phone stays on 1% or 0%. It was charging for a quick second and got to 2% but it stopped.

Hi @alachelle

The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away.

Rice does not fix the problems caused by corrosion Rice is for dinner, not repair

First do not try to charge or to turn on your phone and then remove the battery as soon as possible from the phone to minimize any further damage.

Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion and water. If possible, do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it, check the label to verify the amount of IPA. The higher the percentage of IPA the better

Here is a link that describes the process. Electronics Water Damage

As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the boards. Remove the shields that may be covering some components as the water may have got in under them as well. The ends of any flex cables and their connectors need to be cleaned also.

Hopefully after you have done all this the phone might possibly work correctly again.

Here is a link to a teardown video for the phone which will help.

If this process seems too daunting, take your phone to a reputable, professional phone repair service, experienced in liquid damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later. It isn’t going to get any better by itself.
