Hell of a mobile!

Four days ago...in the middle of a call...my Motorola mobile ended-up at the bottom of a hot tub that reeked of chemicals.

Depth~1meter, temp~41C, time~3min

When fished out of the water a few minutes later, it of course was full of highly conductive chlorinated water and totally non-functional. The display looked terrible and I thought the worst. I immediately removed the battery, and SIM and microSD memory cards, and thought I'd see what I could save.

Using distilled water I totally immersed the parts for about 5 minutes, then rinsed thoroughly, and repeated. Using a short length of string, I centripetally removed most of the water remaining in the phone, followed by drying the parts at the outlet of a PC PSU (~28C) for a few days.

It now works 100%, including sound.

Unexpectedly, the battery swelled-up...a lot. Distending its plastic casing to almost TWICE as thick as normal. Being very careful, on a test bench I verified it still charges, holds a charge, maintains voltage, etc and by all measurements is working properly...but of course it won't fit in the phone. Too weird.


*Of course, had it been an iPhone its warranty would've been voided by the iPhone's water detection sensors

You can just say it in layman's terms: I swung my phone to dry. XD

Nice work, especially the part using distill water, didn't come across my mind until you said it. Distill water does not leave residue, unlike tap water, good thinking / technique. But I would replace the battery just in case. You don't wanna risk an explosion from the battery pack, which will destroy your phone for sure or even injure yourself.

I am wondering is this a Droid or non-droid phone?

My GF one time dropped her cellphone into the sink. Not that wet, but already the phone could not be turned on. I let it dried for few weeks, now it's functioning just as new. Should have use distill water to rinse it, like you did to remove the residue from tap water.

Sorry for borrowing your thread a little bit. Talking about survival, well different kind of survival as John talked about above, don't ever look down on your old low tech cell phone, it could save your life one day.

Nowadays, as people change their cellphones like changing their clothes, it's not unusual for someone to have a few older cellphones. Well first donate your phones for good causes, someone could use it instead of having it eating dust. Save one or two dependable ones for yourself, in case mishaps like drop phone into water which you will need a temp replacement, AND in case of situation where you need a cellphone to survive.

If you ever run into a situation where you're stranded in the wilderness, such as what late CNET editor Mr. James Kim and his family went into years ago ( http://en.wikipedia.org/wiki/James_Kim ), your Smart Phone won't save you! Why because they are extremely power hungry. A 4G capable Motorola Droid for example can only last 1 day of charge in standby and only few hours of use. An iPhone can only last 2 days in standby at most in full charge. Other Android cellphones are not too much better. These phones can not last without a power source readily available.

To survive in the wilderness for few days, you need a phone that can last for a week (or at least 5 to 6 days) in standby after one charge and preferably a flip phone. Why a flip phone? It's designed so it "naturally" protects its mic, speaker, key pad and screen, the most essential parts for a phone to function. It's also the most ergonomic design for a human to hold and talk. At least here in U.S., you don't need to have a cellphone service to make an emergency call. So keep one in your vehicle at all time, keep it charged periodically, and leave it off until you need to use it (hopefully you never have to, but you never know).

Just my 2 cents.

Excellent points!

This is likely obvious, but just in case...a clarification regarding "don't need to have a cellphone service": you do have to have a cellphone signal (which some people call "service")...but this emergency backup phone does not have to be on an active phone (service) plan. If you go somewhere regularly, you'll also want to make sure your backup phone is compatible with the "service" in that area (e.g. GMS v. CDMA) for the area. A CDMA phone (sometimes used in "no contract" phones) won't work in a GMS-only service area and vice-versa.

Also, instead of just turning the backup phone "off", put a strip of paper (not tape) between the phone's battery connection points and the battery. Even when a cellphone is turned "off", it still draws power from the battery and will deplete the battery. Remove the strip of paper before using the phone. I also affix a note to the backup phone's case that one must remove that inside slip of paper to use the phone. Include an automobile DC power adapter if you can.

Depends on what you ate, the chemical composition of flatulence can varies, but in general it contains:

Nitrogen: up to 90%
Hydrogen: up to 50%
Carbon dioxide: up to 30% (greenhouse gas, may impact the global environment ;) )
Oxygen: up to 10%
Methane: up to 10% (contributes to the ignitability)
Sulfur containing hydrocarbons (e.g. Methanethiol): small amount (contributes to the odor)

In normal atmospheric conditions on Earth, these gases should dissipate in matter of minutes. Your cellphone is unlikely to be harmed by this mixture of gases, unless in an exceptionally rare occurrence where an unusually high concentration of methane is produced, and the phone is running in unusually high temperature, hence become an ignition source. Otherwise, you need to worry more about sitting on your phone and causing a structural failure to its exoskeleton by exceeding its torsional strength specification.
