Fuze battery + water = horrible battery life? - Touch Pro, Fuze General

I recently dropped my phone into the toilet where it stayed for about 2-3 seconds. After that i pulled the battery, sim card, sd card and the other parts and let them dry for the better part of a day. When I put everything back it worked fine with the exception of the vol dwn button being activated when i press vol up. After a few days I am noticing the phone is barely holing a charge. It was off the charger for 2 hours and went from 100% - 66% (1 or 2 phone calls and a few internet pages). Should I replace my battery or is it my phone being messed up?

Not even worth troubleshooting. Just get a replacement from AT&T. Be sure to not tell them that you dropped it in the toilet

Isn't there a water sensor sticker on the phone somewhere? Im pretty sure the tab on battery is red too...

i hope u got that sweet insurance.... 125 replaces anything!!!

I think I might try getting a new battery..since the water sensor is there for some reason...

that will not solve your problem. there's another water sticker inside the phone right behind the usb-socket under the back cover...

If you can't exchange it then I would replace the battery. Chances are that it shorted out briefly and probably fried a few cells in the battery.

if the fuze does go in the toilet is it a good idea to flush it with rubbing alcohol to flush out the water and also cuz alcohol evaporates quickly? would that have saved it?

i saved serveral cellphones from certain death with the following steps:
immediately take out the battery (obvious)
dissassemble the whole phone (even the smallest pieces!!!) and flush everything with isopropyl alcohol
put the mainboard and other circuit boards in a bowl with alcohol and leave it alone for some hours
dry the circuit boards with a cloth and put them on a radiator for 24 hours
reassemble the phone and if you're lucky it will work again
i even got phones to work again which took a bath in beer and softdrinks...

Another trick that I have heard is to put it in a bowl of uncooked rice. The rice should absorb any moisture that is around it. I've never had to do it, but it seems like it would work.
Also, be careful with isopropyl alcohol if you use it. Make sure it's the highest concentration you can get. There is a lot of water (50%) in the "cheap" stuff. If you look around you can get 70% alcohol. You can't really get 100% unless you work in a lab...it tends to burst into flames at 70 degrees F.

At room temperature? Not without a source of ignition - I work in a lab and haven't had any problems with that. It is, of course, highly flammable though. You wouldn't necessarily want to use absolute (100%) ethanol though, as, unlike 96% ethanol, as it often contains benzene, which isn't especially pleasant.
Someone I work with recently spilled wine on their MacBook and tried to recover it by flooding the machine with ethanol the next day, but since it was turned on at the time it seems that it shorted immediately and the damage was done. Maybe my old Psion Revo could have been saved from a fall in a puddle which it initially survived, though.
Either way, replacing the battery would be the obvious first thing to do if it's otherwise working fine (bar the volume controls). If it's shorting somewhere nonessential that could feasibly drain the battery fast as well, though?

help water damage tilt

maybe.... I did a search and could not find what i was looking for...or found too much.
This is what happened, it rained, my windows were up. When i got in the car it dropped in the middle console were it was a little water. It was there for a second before I grabbed it and put it in my purse.
When I got home i dried it..removing the sim card and battery. the white thing is still white. It will keep popping up with stuff.
I read if you can get the battery to heat up that will help. is that true?
I work for att so i know i am screwed if there is water damage. i can't buy another one cause i purchase at none committment and the last one cost me 410.
I done retrofited my phone so i will be praying all night that it works.
HELP GIVE ME FACTS
if the white thing is still white and if you have warranty go for a replacement coz i think they only check the white thing. or go to a local phone repair shop and they will do it for a cheap price. i had my nokia repaired from water damage for 15 pounds about 6 years ago.
Tips:
1....Dry it with a towel.
2....Take off the battery.
3....Never put the battery back and turn it on, if you are not sure the unit is totally dry.
4....You can wrap it in tissue (both battery and unit) and put it in a sealed plastic bag of rice grains. Why? Because rice grains are natural desicants. It will absorb all the excess moisture you can't dry with the towel. Leave it there for a minimum of 4 days.
5....You can only place the battery back and turn it on if you are really sure the unit and battery are totally dry.
update
every is working fine. I slept with it to under my pillow. I also check my sim card and that was wet. after I dryed that, i put my sim card in my standby phone.
Everything is working good now!
just a general instuction
1.get the battery out (because watter can't harm it if there is no electricity)
2a.dry it with a towel,just to get rid of any water that could float out of it
2b.dry it with a hairdryer or a radiator. (don't expose to fire)
3.instead of ryce you can use ethanol ( C2H5OH ) to get the water out and to clean it...use a brush to do it
4.try not to drop it again
personaly i dismantle the device when drying it...that way i'm sure there is no water left in it
but for inexperienced people or those devices with warranty...i suggest you don't dismantle it
I took the battery out and placed both battery and phone into instant rice. Works great
working fine
my phone is working fine.
It had some problems, it was the keyboard, kept acting up. so open it and let the keyboard dry (i don't use the keyboard...lol) took out the sim card and dried the area where it was, a little bit of water was on it. Dried it, and put it under my pillow for heat..lol.
Took it to work the next morning and it was having trouble with alignment when i used the stylus. so after redoing the alignment it has been working fine.
Thanks for the help.
Close the thead
Can anyone close the thread for me?
Dropped mine in the toilet!
The unthinkable happened. I have insurance on my tilt... but the thought of a whole day re-flashing and installing software made my stomach hurt.
I did the following-
1. Took out the battery within 10 seconds
2. Took out sim card & the microsd
3. Shook out all the water I could
4. Used a whole can of compressed air to blow any moisture out
5. Placed in a bag with silica gel packets for 30 hours
I was amazed when the thing booted right up! EVERYTHING works perfectly- wifi, GPS, camera, speaker, mic, buttons, and touchscreen! This thing is a tank!

Fuze Problem (Help)

My Fuze got a wet.
I shook out the water
I powered it on. It came on and everything.
It reset itself.
Then I played with it for a while.
Everything seemed fine until I hit the power button. The screen turned off.
I pressed it again and it wouldn't turn on.
Nothing gets the phone back on at this stage, except taking the battery out and powering up again.
I then decided to do the bowl of rice thing and let it sit for about 7 hours.
It is still the same. If I press the power button at the top of device, it turns off.
If I press it quickly after, it turns back on but if I wait a while, lets say 3-5 seconds, it doesn't turn back on.
Also, the water damage sticker has turned light pink, like 65% of it.
any suggestions
I'm afraid there is probably no help. Even if the water dried completely before turning it back on the impurities in the water probably will cause problems.
I had one drop in some water. Powered it off, disassembled it and dried completely. I let it sit for 8 hours, reassembled it and powered it on. It worked for a couple of hours.
Luckily I had insurance on it.
oh ok
what about warranty, i am still covered
the little white box is still white but mostly pink
its kinda crazii that it turns on and everything works
its just that if i turn off the phone or it turns off automatically due to the power settings, it can't turn on.
the soft reset doesn't work and the power buttton atop the phone doesnt work either
w0w!!!
i just powered on my waater damaged 8525 from 2 yrs ago (had a tilt & fuze since) & it works!!!
b4 it would turn on but the screen wouldnt work
you would have to position it @ a certain angle in order to make anything out
it works now, besides needing to hooked up to the charger in order to load up
fuze is still sitting in a bowl of rice
any more ideas, suggestions...etc
ok, i just realizedthat the soft reset button @ da bottom doesnt function @ all
any idea on how to go about fixing this??
itsjust the screen doesnt come back on but device isnt off because the scroll wheel lights still show up
but it shouldnt because the device isnt charging
Can you warranty a device if the sticker is partially pink?
You can try the warranty, but when they see the water sticker is colored, you're likely to be charged for the cost of the phone. Water won't be covered by warranty, only insurance.
If you want to avoid replacing the phone at your cost, then about the only thing I can think of doing is pulling the battery out and cleaning it thouroughly with distilled water (in other words, another dunking). Do that 2-3 times with fresh distilled water to get rid of as many impurities from the other water as you can. Then let it dry for 24-48 hours (getting some dessicants wouldn't hurt to suck out as much water as you can). Then put a battery in and see what happens.
Odds aren't good this will improve things, but it's possible. It's more likely you'll need to get your hands on a new phone.
You could also try to find a broken fuze online, maybe eBay, but no water damage, and swap stickers.
thanks guys
do the silica packs count?
how would you go about switching the stickers?
is there a particular part i can switch from a used fuze to fix my problem?

For the sticker, just carefully take it off a different Fuze, hell maybe even a different phone as long as the sticker fits. Take off the pink one on your Fuze and glue on the new one. Should be good as new.
As for swapping parts, it would probably be too much money and trouble to do that, that'll void your warranty right there anyways and there's a chance you'll never assemble the phone back perfectly. Trust me, it has happened to me a lot when I thought I could swap parts.
I've seen a friend of mine do something with one he got wet that actually worked ... he dipped his entire phone in a bowl of rubbing alochol for a few seconds - the pulled it back out & let it dry out for about 24 hours and it's worked. Obviously take the battery out when you do that....
kinda scared about the rubbing alcohol because the phone works for the most part, just not the reset button
i have other devices so im gonna try the sticker swap for now
well the concepton the alcohol dunk is that you need alcohol that is as close to pure alcohol as possible. rubbing is great as previously mentioned. what it does is that it takes the water and vaporizes with the water. the same concept as adding wine or spirits into a soup. it makes the soup thicker and creamier because there is less water in it.. and it also can be used to fix a situation where you use too much water or something....

My phone was in the freezer. Is it bad?

So uh... I woke up today looking for my phone, I couldn't find it anywhere... figured I lost it, oh well.
When I went to the freezer for some sweets (about 10 minutes ago), I saw my phone in there. I don't know how the hell it got in there. The phone is off. I don't remember if I turned it off, if it ran out of battery before (or while in) the freezer, or if it's broken.
So the question is:
*Will my phone be functional once it "defrosts"?
*When should I plug the charger back in?

Let it defrost and dry first. Battery out and you should be ok. We you drinking? There was one time at a NYE party I put all my junk on top[ of the fridge and it fell in the freezer some how, but I was drinking.
Lmao, how in the hell did you manage to do that?
You had to be heavily drinking, or so I hope!
Anyway thanks for the laugh and I hope it thaws out!! Lol

I fear you've already removed the phone from the freezer, so it might be too late but here is my advice. Don't take your phone out of the freezer until you have a big bag of rice ready. Remove phone from freezer, remove the battery cover and sim cover, take out the battery, sim and sdcard, then put the phone into the bag of rice (with the battery and sim covers removed, and make sure phone is completely engulfed in rice on all sides). Once the thawing process begins, the phone will start to sweat. The rice will absorb the moisture that it comes in contact with. Leave the phone in the bag for a couple of hours until it reaches room temperature. Then remove the phone from the bag and spray compressed air into every hole, nook and cranny of the phone. Then let the phone sit for several more hours or maybe a full 24 hours. Then insert battery, push the power button and, if you're religious, pray.

I once managed to salvage a phone that I dropped in water by blow drying using a hair dryer. Remove all the doors/windows from the phone and use warm setting on the hair dryer. Try to work the air into headphone jack, speaker, mic holes and other crevices.
Good luck!
I know somewhere, maybe walmart, or a cell repair store you can buy these bags that are made spacificly for water damage, your supposed to immediatly take apart the phone and put it in the bag for like 11hrs, better than having rice all up inside your phone, it works the same, but i dont think its a good idea for these types of phones, still good idea though
I saw it on the news, this lady took her razor and dropped it in a pool, put it in the bag, and the next day it worked like a charm
Phone should be fine and it only makes condensation with the sudden change of temperature, not defrosting it isnt wet.
I've recovered
several phones, laptops, electronic devices over my years from water damage by either using a hair dryer of if it's winter stick it in front of my abode's heating source. I've always heard about rice and silicate n all that stuff but heating sources as quick as possible always worked for me. I would think if just frozen you wouldn't want condensation on the inside of the thing during the thawing process...hair dryer.
Honestly, its no different than leaving them in the car in our cold Wisconsin winters.
What you did is freeze the battery. Once a battery gets so cold, it quits being able to generate power. Pull the phone out, set it on the table, and let it warm up slowly. Don't be tempted to add heat, it will warm up the battery too fast and cause damage.
My wife forgets her phone in the car from time to time, and this is all we've had to do.
I actually put it in the fridge, afraid of any potential condensation in quick defrosting, in this summer heat >.>. Was planning on taking it out of the fridge tomorrow morning and let it sit room temperature (like thawing a frozen meat =P).
I don't understand why there would be any water damage. From room temperature to freezing temperature at a rate of your average freezer would create condensation...?
I too have left my phone in the freezer one time,I just took it out and let it sit on my dresser for about 2 hours. The room temp was about 70 degrees. After 2 hours I stuck the battery on my little portable charger to see if it would charge so I would take a risk on it harming the phone or something. And it charged rite up. Stuck the battery in the phone and left it off while it charged for about an hour ab a half,then powered it up and it worked fine.

I have heard of the bag-o-rice trick. One time my brother dropped his Droid pro in the toilet (clean water thankfully) and he took it out and put it in rice and it dried within a few hrs and was good to go.

For drying out electronics remove the Battery quickly as possible! Then wrap it tite in a diaper for 24 to 48 hours, place it in a warm dry enviroment. The gel in the diaper is the same as the little packets the ship with electronics to keep them dry (the ones that say "don't eat"). It's ten times more absorbant as rice. I've saved a lot of friend phones an mp3 players this way. (you would be amazed on how many people drop their phones into toilets, dam the hooded sweatshirt!) The key in saving your device is pulling the battery as quickly as you can!

Thanks to you and all who replied... I knew exactly what to do... with my wifes cell that mysteriously after about a month ended up in the... freezer.....
I took it out took out battery put it in rice, used blow-dryer to dry it a bit.... after about 20 - 30 mins.... (maybe a bit overkill but.... better safe then sorry?) turned on phone.. VIOLA THANK GOD! WORKS!
This just happened to me. All was well for my Note 3, despite it being in the freezer for several hours. In my case, I wasn't drunk, but I had placed my phone in the freezer, as odexing was overheating the device, since installing a new ROM. What I did was put the phone face down on a table to let the condensation flow downwards, and waited about 10 minutes. Actually, the phone was even working when I took it out of the freezer (immediately!). I could feel the frost on the screen, and the blurriness from the condensation already formed.
Its probably to late... but DO NOT USE A HAIR DRYER on hot. It WILL harm the battery and can damage the other internals of the phone.
my daughter put her phone in the freazer and forgot about it.now it will not charge at all.is the battery asleep or is it cactus

[Q] A "washed" through laundry HTC Diamond

Hello,
by a rediculous accident I forgot my HTC Diamond in the pocket of my jeans when running the laundry :-(
Afterwards, I opened the cover, took out the battery and let the phone dry out for 2 days. Now I've put it back together, and connected it to the charger. The "ring" is flashing, so the battery is charging but the phone itself is not starting and the display remains completely black, not even the vibration kick on starting...
Is there anything I could do? Or perhaps there is a chance to get out some photos I have shot earlier, would also be something...
ive heard that taking apart your phone and leaving the parts in rice can help (because the rice absorbs moisture)
Off topic:
I read one Desire went through a washing sequence in a washing machine in Desire spesific forum and now this?
Is this a new hobby? I mean... washing smartphone

If the photos are on your micro sd card, you may be able to plug that into an adapter and plug it into your PC and gain access to them that way. Just be sure that micro sd card is thoroughly dry before doing so.
WORKING !!!
Hello,
thanks for the replies... This morning the phone booted!!! I was able to download the photos!!! But the screen has stains, obviously the remaining water.
PLEASE advise on how to dry that thing completely !!!
I think that I'm gonna pass on the rice thing.
@aaa - YOU ARE A JUNKA$$ !!! You think that's really funny?!? Especially when I'm currently TIGHT on budget and need the money for other things and the next phone is planned no earlier than Christmas... I'm hesitating whether you're a real human being...
You can dry it completely in an oven for three hours at thirty degrees or so. I've done this three times. If you have a fan forced oven, just turn the fans on, that'll be enough.
A safer way (if you can obtain it) is to leave the phone for 24 hours in a bowl of dessicant silica gel. You'll often get a small packet of silica gel when buying new electronics or other moisture-affected things. That small packet is enough, just put it in an airtight bag and leave it for 24 hours.
The next step would be disassembly and a thorough swabbing with denatured alcohol, but that's pretty extreme and only needed when the device isn't booting.
Some LCDs are hard to get moisture out of, some are not. Leaving the phone with the silica gel for longer will have a better effect. As the previous poster mentioned, rice also works (quite well), but takes longer than silica.
Good luck with it!
Another thin that will absorb moisture is common table salt. Take the phone apart very carefully. Remove battery first, make sure you're grounded as well.
Hello everybody.
thanks a lot for the numerous advices...
Unfortunately, I have more to report...
The phone dried out and booted 2 or 3 days later, as I said. The stains on the display disappeared as by magic one day later.
Everything was fine for a week until I launched the camera 2 days ago. The backlight of the display went off and came back only after removing the batter for 15 minutes.
Now the backlight is going off pretty often, sometimes it requires to remove the battery 1-2 times before it starts working again and yesterday it happened that it got activated again when I got a call...
Any ideas please?
And also the phone keeps overheating from time to time without real load (GPS or wi-fi) which dries out the battery. But I had this problem also before the laundry
Sounds like that moisture in the LCD unit left a bit of residue and is shorting the backlight somewhere.
Only option there would be to disassemble and swab the LCD boards and cables/connectors with denatured alcohol.
Alternatively, a new LCD unit should fix the problem if it persists, just make sure you alcohol swab the connectors before plugging them back in
Someone also mentioned drying out in salt before. While that does work, salt is extremely corrosive on solder and SMCs, so I wouldn't recommend that route.
i heard hair dryers are the bomb at the screen moisture, just take off all that you can and blow dry it.
I just don't understand your refusal on using white rice. It have saved countless phones.
Uncooked white rice is VERY mosture negative. Just put layer of rice, put your phone on it, cover it completely with white rice, seal it in. Ziploc could work too.
In a day or two your partially dry phone will be bone-dry. If it was soaked still you could first try to shake out water as much as can, soak it in distilled water to remove minerals, then white rice it for 3 to 5 days.
I had this problem with my Touch Diamond. Everything worked, but while i was trying to dry it I broke one of the battery "hinges" but the phone still worked after except only with black screen. The best thing to do probably is just leave it for a couple of days and hopefully your phone will be back!

exactly what ive said. ive read everywhere that rice is one of the best solutions out there
Like was said before you most likely have some corrosion on a few contacts, if you have about 6 bucks you can spare you can get residue free contact cleaner in an aerosol at radio shack or any electronics store and save yourself having to scrub each contact and connector. Just tear the phone down down spray all the contacts and connectors with contact cleaner let it sit for a few then spray it down with air duster to get any thats get under the resistors, in the connectors, etc that hasn't dried; let it sit till you're positive everythings dry and put it back together. Does the same thing as alcohol just alot less scrubbing.

Hello,
thanks for narrowing the problem down.
But for me it looks like something different, because:
1) I have been using the phone for 1 week without any problems and it got screwed after I've launched the camera app for the first time
2) The backlight works when I power on the phone. But its stop is event-triggered, like when I launch the sound or video player or when I get a call... Similar events would trigger the backlight back on.
Perhaps reflashing the software could fix that?
I went to a shop today and put another battery. The phone booted, anyway without any backlight, twice...
At least the device is still alive.
There probably was a tiny water bubble and it messed with phone when you turned camera on.

Either that or a short in the cameras circuit from corrosion, either way i'd pull it apart before it gets worse and check it out.

How to check dissembled Pixel 4a Mainboard?

Hi all,
I ditched my phone in water.
I disassembled the whole phone, cleaned everythign with IPA and dried it afterwards. Now I would like to check if the mainboard is still working.
I connected the battery, display and usb port to the mainboard and plugged a charger in -> no response (display black, no vibration, sound etc)
I assume that the batterie is completly dead as it discharged until it turned off.
Is this aready a clear sign for a broken mainboard or does it only boot when fully assembled? Just want to avoid to put more effort into the phone, e.g. replacing the battery etc if its already lost...
Thanks in advance!
Dry for at least 72 hours in a warm dry room with a fan on the mobo. The BGA chipsets can dry slow.
Isopropyl is hygroscopic so it's important to remember it may attract some moisture from the air while drying. Use only >92% or greater, 96% is best. Submerged the board in it for a couple minutes while moving it around.
Battery needs to be charged and good for the phone to boot.
Out of circuit the mobo especially is sensitive to ESD damage. Use your best judgment but more assembled is better than less assembled unless very familiar with the device.
Thanks for the reply! Phone is "drying" for two month now as I was already considering as "lost" after disassembling and no luck with first checks. But before getting the new 6a, I want to give it a last try Was just 7 month old when I dropped it :/
When I plugged the charger in, there was no sign of charging. So not sure if the batterie is broken or if its coming from the board, or both.
A new battery is quite expensive just for a test / to find out more is damaged.

Thanks for the reply! Phone is "drying" for two month now as I was already considering as "lost" after disassembling and no luck with first checks. But before getting the new 6a, I want to give it a last try Was just 7 month old when I dropped it :/
When I plugged the charger in, there was no sign of charging. So not sure if the batterie is broken or if its coming from the board, or both.

If the battery sat near its auto shutdown voltage for 7 months it's DOA.
A charger likely won't supply enough current to boot.
The fact that it does nothing when connected to the charger is a bad sign.
Check for loose connectors, bent connector pins, etc.
Examine the mobo (power section especially) and connector pins closely for corrosion damaged caused by electrolysis.
Since you can't see the BGA pads if there's corrosion there...
Water exposure; power off immediately and pull the battery asap to limit damage. Salt or brine water is a death sentence though.
Anhydrous isopropyl alcohol is an excellent drying agent but it and any solvents can't be used around LCD's; it will irreversibly poison them.
LCD's are vented to atmosphere on the sides...

Thats true, happened at work so I could do anything for the whole day and in the evening it was already dead. With some random screen on and offs during the day and "booting into fast mode" or something similar during the day.
Phone was not reacting to switch it off normally, screen was black and buttons did not react either

A thats interesting, I was already thinking that some water went inside the screen. Because I have quite some dark areas on the screen, which increased in size the first days. Looked like water got pulled in. Was hoping that when the phone gets warm again it will disappear...

Yeah, have the same feeling. Very unlucky as it was just rain water in a not perfectly closed rain jacket...
Will check the connectors and cables again but was already quite sure that they are all clean

That sucks. Prompt battery disconnect* can save electronics (flooded cars sometimes too).
LCDs are sort of witchy. The spot may or may not disappear over time. Have an old S4 that got sunbaked while charging. The display had multiple issues, barely usable. Thought it had fried drivers. Strangely the longer it sat unused the better it got. 3 years latter it almost 100%.
*Lol, 3 years ago I dropped my Buds case in a full cup of coffee, cream and sugar of course. It promptly sank to the bottom like a lead weight.
The Li is spot welded in. Immediately tore it apart, flushed with RO water, then with anhydrous isopropyl, allowed to dry for a day.
It's still working normally today. A drank that cup of coffee afterwards too
