infuse went swimming only workes when on charger

First things - turn phone off, remove from charger, take battery out. Leave in this condition to avoid further damage which may occur when you apply power to a wet phone.

Also, getting started on the drying process quickly is somewhat important (but not so important that you should rush to do anything without finding some instructions first).

Google using three words
wet phone rice

The first two hits look good:

Sorry, I misunderstood. Yes that's a lot harder question.

You apparenlty have a high battery drain.
You've ruled out battery by swapping.

I guess before trying anything drastic, you might try typical approach to see if there is an application drawing battery (for example power tutor). That's a longshot since it would be unrelated to the water, but would be a shame to get intrusive if it's not required.

Other than than I guess you can try to have it cleaned to remove some contamination that may be causing like high-resistance short circuit causing a battery drain. I have no experience or recommendations on who might be able to do that. If trying yourself you might try inspecting accessible areas and disassembly to gain more access to the extent you feel comfortable. Possibly clean with compressed clean air or q-tips soaked in alchohol.... targeted cleaning if you can see corrosion, or longshot just clean everything in sight.... but that increases the risk level of something that is already risky (easy to damage things poking around inside your phone). If it were my phone I'd definitely be looking for someone else to do it rather than trying myself.

Sorry, not much help. Maybe someone else will chime in...

Sadly.... It is probably something on the board of the phone. If it only works when it is on the charger that means that no power is going from the battery to the motherboard. Same problem with a 3gs. Although that turned out to be a curoded chip on the battery itself, there is probably a bad part on the motherboard. You will most likely have to take it apart and look for water damage. Like curoded spots, and clean them of by CAREFULLY scraping the white off with a TOOTHPICK or something else soft and non metallic. That's all I can say, I've fixed a good many water damaged devices. But they all had on board battery's and the same part always went. The little chip controlling charging on the battery.

If you get it apart look around where the battery prongs are. Either there or maybe around the processor.

Did the phone get powered on straight of water???

If so corrosion is a possibility more that likely the currenent arched and damaged the circuit .

Does the phone heat up when running off or on the charger ???

Again if so then phone motherboard. Was damaged and the power circuit is causing the drain and allows for it to function on the plug because it bypasses the damage.

Just my humble opinion....
My only suggestion is if our handy with electronic find another on eBay and switch out mother board.

Also may besomething by the battery connections causing a bad connection resulting in.bad power...just another idea

Others have recommended this product for cleaning gunk out of the buttons on Samsung phones. It also works to remove corrosion on electrical contacts - plastic safe, no residue. Might be worth a shot if other avenues don't pan out (available on Amazon and elsewhere):
