sporadic power off, how do i diagnose the problem ? - G2 and Desire Z General

the problem:
phone sporadically powers off,
sporadically reboots when connected via usb to computer
bad battery data is show in notification bar.
usb port works for charging but does not recognize computer when connected.
additional evidence:
water damage
using custom rom (signature).
the story:
the phone has sustained water damage.
it did not go swimming, but water that was slowly spilling from a cup leaked near the area of the phone and the bottom lid did get wet.
being the idiot that i am i just wiped the bottom and continued using the phone.
it would no longer charge the battery, so i assumed the battery was dead, replaced it with the one from my signature and continued using the phone.
after a few days the usb port started exibiting the above behaviour,
and a month later (2 weeks ago) the current problem started.
long story short:
I don't mind buying a new battery, but since my phone is not common where i live, i would have to pay extra for shipping etc
I need to be sure this is the battery (or batteries, both work but are problematic) or be sure this is something else in which case i buy a new phone or get the current one repaired.
ideas ?

At risk of double posting, just wanted to let you know I'm having very similar problems, but with no known hardware damage.
Mimicry 1.4.0. See your original posting for more specifics.

I would suggest doing a couple of things. First, I would clean the contacts to your battery. I actually used metal polish to fix a problem with the G2 when I closed the qwerty keyboard it would shutoff. Lots of oxidation was on the battery contacts, and I cleaned the metal connectors to the battery on the phone itself as well. Sure enough the problem doesn't occur anymore.
As for the USB port, could be the same issue. Corroded or oxidized contacts, probably from a drink you spilled. Damn near impossible to clean that connector, I would suggest getting yourself contact cleaner/lubricant. They sell it at RadioShack, and it works miracles. I use it on damn near any electrical connector. If you really want to go the extra mile, put some dielectric grease in there as well. Will help to keep the connector from corroding in the future.

I had this issue when I dropped phone in a toilet (ewww) . Anyways I opened the phone and cleaned the mobo with 99% alcohol. I used a toothbrush to do this. Phone stopped rebooting and powering off. The reason to use alcohol is because it evaporates quickly and nonconsuctive.make sure is 99 percent tho because of less water content.

I've the same problem (no water accident)... sometimes my desire z turn off... it happen with mimicry 1.4.0 (and prec version) and now sometimes with Ice Cream Sensewich 1.0

I'm having the same problems, Mimicry 1.40, with no water damage(that I know of). They've been getting worse the past few days. I'm not sure how to read the logfiles that might help diagnose the problem... any ideas?

Water damage isn't the only way to oxidize a connector. Dirt will do it just fine. I'm using Mimicry and haven't had this issue.

:( OVERHEATING battery!! whats wrong?

attention:: long post, read fullyy
My battery really overheats now. I was at a club 2 weeks ago my phone dropped with my battery popping out! there was a tiny bit of water on it, but i put the phone in a bag of rice for 3 days. I then tried to put the battery in, it was dead. I then proceeded to go to 2 Mobile repair people and get them to look inside my phone to see if there was water damage! 1 said there was none, the other said there was some.
I found out later that my phone still turned on with a friends battery so i left my phone on the table for 2 weeks, ordered battery off of ebay. I found out that i could bring my original HTC battery to life. Charged it last night, and now SPARE Parts is telling me its too hot and overheating and it is!!.....Everything on the phone works fine, Everything! except the battery is getting VERY veryyy hottt arounnd 48-49 C. when the normal for me was 38-41 C. any ideas? i really dont want to sell the phone, i know someone would buy it with a battery problem
Battery + water is the worst equation you can have.
Overheating battery can explode (rare, but possible in your case), stop using your phone and get a new one ASAP.

I have just charged it and left it in rice today. I checked this morning and the battery didnt overheat, the temperature seemed fine. Im going to test it after work today and if it overheats ill give it away or something. But Hopefully it wont.
I know you've been on here for a while but I figured I throw down some basic suggestions if it starts doing it again.
Are you oc'd? What to, and which CPU manager do you use (CM or SetCPU)? Do you have a temp profile set for SetCPU?
Is there a process that's eating up your CPU clock cycles? DRM, Downloads, and 3D Gallery cause the Android Media process to make the CPU max out it's set clock frequency sometimes. So check that if it does it again.

Lets get this straight... your problem is with the ORIGINAL battery, not the replacement one you ordered off efag?
You smashed the new battery, its probably shorted out internally. Wait for the new one to arrive, try it out, and then come back here if it is still doing the same thing.
Order a new OFFICIAL HTC battery. You're making it seem (at least to me) that it is the battery not the phone that is acting up.

Just dried out the phone and my htc battery seems to be ok. But i dont think it will last, i might just buy the orginal one from the HTC website. The chinese batteries i got from ebay are crappy and die within the hour.....(voltage issue with my phone maybe??)
Im charging the htc battery right now, ill see how it goes, it drains 1% every 2-3 mins, i believe its a battery fault, Im just gonna order a HTC battery.
I am OC and it does overheat when doing things, but now it seems fine, the temperature reading is fine and same as what i have had back when i originally had it (before damage)
Will be buying new battery, i guess i gotta fork out the $50 for the official one
Edit** just bought the brand new ones for $10 from Ebay. I hope my phone isnt overpowering the batteries.
It wouldn't hurt to take apart your phone and clean off any corrosive material left on the board.
Just follow one of the tutorials for disassembling and use a old toothbrush and rubbing alcohol to do so. Use the alcohol very carefully and apply it to the brush directly and not the board. Good luck!

Could you link me to a video or guide doing that? Im super paranoid when taking apart something i love .
I tried the orginal battery, (temperatures fine, but went down 1% every 2-3 mins)
^^ i tried the 2 chinese batteries (1500mah) i got for $10 from Ebay and they also DIED, (draining 1% every 2-3 minutes.)
What is the cause of this??? I Doubt 3 batteries in a row are faulty?...
Does anyone know how to fix this? what would cause my batteries to be drained 1% every 2-3 minutes? the phone lasts less than 1 hour.
I have tried 3 batteries......any help is appreciated.
your phones has water damage most likely.
my previous phone got water damage from me using it in the shower.
(not literally in the shower bu i had it by the sink cuz i listened to music)
im assuming water vapor got in my phone and messed it up.
afterward i started experiencing what you are. tried different batteries but the phone killed em quickly.
tried the batteries on other phones and they worked fine.
I came to the conclusion that it was the phone that was damaged and not the battery. like with yours everything worked except it died fast.
try the batteries on other phones and if they don't die fast then it might be your phone that's water damaged. I think you can draw the same conclusion if batteries that work on other phones die on yours quickly. must be th same phone of course lol

thanks buddy! finally some good input. I gave it to a repair shop who apparently said they can fix Shortages on the main PCB board. expecting a call tomorrow. I take it you just had to buy a new phone??? what happened to your phone now?
So FutureTel Solutions said they can fix my phone in Ontario.....its water damaged and will cost about $250 or less to replace.
My question is: Is the price worth it? I for one dont like any of the new dual core phones coming out as i am a Hardware keypad guy alot and like the feature of having both of best world. Is it best to fix it? they'll just replace the board and send it back....

Sprint 4G Evo wont charge, replaced power port

A customer brought a EVO that apparently has water damage and will not charge. I charged the battery via an external charger and it works fine, i replaced the power port but it still wont charge.
I put the phone on my BGA station to heat up the phone and get rid of all the moisture and yet it still wont charge but works with battery. Its possible its a BGA chip, but all the components LOOK fine.
Any ideas??
Water damage is tricky, it could have damaged any number of chips on the main board. Your best bet is to replace the whole board itself to avoid future problems.
Hey,
Sorry to hear about that, water damage is always tricky because you never know to what extent the damage has occurred. I would try the through it in a container with rice trip to make sure it is completely moisture clear, but I really doubt that will work. It sounds like the water fried something between the power port and the mother board. sorry about your troubles hope you find a solution!

That wont work at this point, the damage has already been done by the previous user trying to turn it on when the phone was still wet.
Yeah ive had it where mine wont charge b4 too, but it was bcus of a universal charger I was using I guess, cus it doesnt work now either

short circuited my note

Hi everyone,
First of all, I apologize in advance,
1. Because I know this isn't a tech support forum.
2. Because I don't contribute and help out as much as I should.
Coming here was a last resort, I don't consider myself a noob, but I'm really stuck here.
Please note that I appreciate every single response, and I will donate if anyone can give me a fix.
With that aside, let me get started
__________________________________
Okay so about a week ago, I accidentally bent my charger when it was charging my note.
It didn't charge at all that night
That morning, I blew into the charge port on my note, suspecting that dust may have been the cause.
Somehow, that helped, as my note charged fully that day, in about 2-3 hours
Then I tried charging it the next night.
It charged incredibly slowly, reaching about 70% after 10 hours charge
The next few nights were similar, but reaching no more than 40% charge after 10 hours.
It got progressively worse, it would only charge if I applied pressure to the mini-usb,
I looked around this morning, and stumbled across another guy with the same problem
(see here http://www.galaxynoteforum.net/galaxy-note-help/charging-port-issue/ )
He advised,
"Well I have figured out the issue. If you look into the charging port slot on the phone you will notice a small thin flat piece of metal which inserts into the charger. That was slanted and angled downward which would not let "ANY" charger or docking station charge correctly also causing it to drain the battery. Contacts on this piece and the phone were to close causing a minor contact draining power. I used a precision flathead screw driver and lifted the piece slightly and now works fine"
So I tried that, and it seemed to help, as the note began charging, (extremely slowly, reaching about 30%)
Then I tried pushing that "thin flat piece of metal up even further"
However, I went too far, and I couldn't fit the charger into the charge port.
So I tried pushing it back into the centre but I may have damaged one of the pins in the charge port (inside the phone)
I seen a little spark, and the note turned off.
I tried switching it on, and managed to boot to safe mode (no idea how)
So then I tried charging it, I applied pressure and managed to get it to start charging. (thank god)
This was about 30 mins ago, it looks to be holding the charge at about 20%, but it's not increasing
-----------------------------------------------------
I suspect one of the pins in the note charge port was snapped off.. although I'm not sure.. (it appears to be the one on the right)
1.Does anyone know how many pins there are on the charge port inside the note? (is it 4 or 5?)
2.What should I do?
If I broke a pin, it should not charge at all, right? (but it seems to be charging)
3. Do I need to replace the charge port, if so, how much would it cost?
4. Would I be better off getting a charging station, and charging the battery using that
5. Should I try moving the metal strip again? (inside the charge port of the note)
oops forgot to mention, when the problem started, and the note was slow-charging, an audible buzzing/humming could be heard in the wall outlet
also, I'm using my original samsung usb charger, not a generic one, and I'm charging directly into a wall outlet.
------------------------------------------------------------------
Thank you for taking the time to read this, I really appreciate it, and any advise that you do offer.

Here my tipp: You can go to a service center, maybe they even repair it under warranty. Or you can order a new micro usb port and replace it. Google should help you to find a seller. Depends on whether you feel comfortable enough to replace it yourself or not. Oh one more thing, I would stopp using your Note to avoid any further damage.
Sent from my Galaxy Note running ICS
there are 5 pins on the charger slot, 4 I believe are for data transfer and the 5th being the one that draws power (charges the phone)
Have you tried transferring data from PC to Phone and see how that pans out ?
Its possible to replace the USB port, Ive seen a few threads about this on XDA, A quick search should chuck out some results.
But as mentioned above, Try to claim under warranty first, if you have it, or pay the Service centre to do it if you dont feel confident enough to do it yourself.
I think I recall someone with a similar issue and it cost him / her $60 for USB replacement (convert that in to your currency)
If you have a friend with a Note or a phone that fits the Note's battery you could always charge your battery in that phone and place it into yours until you get it fixed.
IF YOU MUST charge your Note ( you could if you intend to get a new USB slot) I would suggest to charge only via USB - as in charging from your PC / Laptop / TV / PS3 etc. As this will not draw as much current as it would coming directly from the mains supply!
Good luck on getting it fixed, And please keep us posted with the results !

Thanks for the quick reply!
First of all, I can confirm that no pins are broken or bent, everything looks normal, it also seems to be charging better, as I centred the metal strip in the charge port.
As for warranty, well I didn't purchase any extended warranty or insurance, however, the standard warranty lasts 2 years.
Unfortunately
The Repair Warranty Exclusions are as follows: (i) Subject to the inclusions of the applicable manufacturer's warranty, a mobile that has broken down or is damaged as a result of: (a) abuse or tampering, (b) electrical damage, moisture, dampness, oxidation, corrosion or food, dirt or liquid ingress (c) accident, neglect, impact, actual or attempted theft, fire, power outages or surges, or incorrect voltage, (d) transportation or packaging (e) removable batteries or damage caused by battery leakage
Basically, the only thing that I'm covered for is "handset breakdown"
My phone is in perfect condition, and no pins are broken or bent (as discovered on closer inspection)
So do you class charging issues as "handset breakdown" or not?
I may purchase a new charger, just in case the issue is with the charger, and not the phone,
What d'ya think?
Thanks again for the quick replies azzledazzle & nipuna, I didn't notice them until now,
Yeah I'm 90% there's no damage to the pins on the charge port, and it seems to be charging now, slowly at least,
I've centered the metal strip as best as I can, (inside the charge port)
I'll leave it to charge now for a while, as I'm not sure if it's fixed or not
Then I'll try another charger if it doesn't work
If all else fails, I'll try getting it repaired under warranty
(although that's more of a last resort, as it will take a few weeks to get my phone back)
does anyone know if the standard galaxy s2 charger will work on the note?
I don't have it on me now, although I could borrow it from a friend
I know its an official samsung charger, although not sure if it's the usb or the other kind.
I'll let it charge for a while, then I'll try transferring data from the laptop, to make sure the pins are fine,
thanks for all your help everyone,
1st of all: if you go poking around in the usb port with a metal screwdriver, take out the battery first. Not only will it avoid shortcutting and maybe blow a fuse inside the phone, but it will also protect you from an exploding battery when shortcutted !
S2 charger will work

[Q] Battery expanded and broke glass back

Before anyone go crazy, it's most likely my fault. Since the battery is superglued to the phone I had to bend it pretty hard when I replaced the screen. And it was probably damaged
Anyway 6 month later my battery expanded and broke the glass back. There is a very visible bulge on the back (~1/16" thick), on a flat surface the phone wobble. I don't know when or how it happened, at some point I got the phone out of my pocket and it was broke.
I have a strong suspicion it happened while using a 2.4A/12V car charger at -25°C.
My real question (TL;DR) : Is there a risk using a 2.4A/12V car charger ? (my previous one was a 1A and it was barely charging the phone)
Doesnt matter what the current output of the charger is. The device has current limiting technology. It will max out at 1A so if your using a 2A charger your fine.
Also the car puts out 12VDC but it gets stepped down to 5V at the micro usb port. Thats the industry standard.
Now when you bent your battery you started the process of damaging it. Li-Ion batteries have a very thin sheet with paste on it and that is wound up with many layers. By bending it you probably flexed the thin sheet and that soft spot eventually broke and when that happens a chemical process begins to break down the battery. The bulging you are seeing is a buildup of gasses inside the sealed battery its self. When a battery begins to bulge its going bad. This can also happen prematurely if you expose it to over heating repeatedly OR for a long period of time, OR if you allow the battery voltage to drop to low for to long. Li-Ion just doesnt like heat or low voltage.
I concur with IAmSixNine you need to either replace the battery or get a new phone. And be sure to dispose of it properly. I had the same problem years and years ago with an old HTC touch diamond. The battery started bulging and I eventually had to remove the cover and use tape to hold it in. After a couple weeks it burst and it wasn't a pretty site... Pretty dangerous carrying around a battery that could explode in your pocket at any time.

Thanks, good to know that the charger can't damage the battery, I have purchased a new battery lets just hope this one does not explode in the mean time
Ive replaced the battery, the first charge took 8hour to 90% and now it wont charger over 50% is there a way to reset the battery limit ?
Sent from my Nexus 4 using Tapatalk
let it cycle a few times to correct the battery information.
That means let it die down completely, then charge it completely. Do that a few times and if it still causing issues its possibly a bad battery.
I think I also have a faulty charging port, only the wireless charging is working now, when I plug into any usb there is the lightning icon but it says not charging. I'll switch the daughter board with the one from my other broken nexus 4 to see if it fix the issue.
As much as I like my Nexus 4, I'm not impressed by reliability. In under 2 year, I've had 2 broken screen, 1 broken bake cover, 1 expanded battery and now possibly the charging port. My nexus S and Galaxy nexus with a million drop each are still working as new
One of my friends got one and broke his before the 2 month mark. He was ribbing me about getting a case for it and making it more bulky. I was not the better man...

broken port tab

so I broke the tab in the usb port in my nexus 4. I bought an induction charger but it doesn't seem to be charging the thing very well. It will sometimes turn on and I can see the battery is at 0% and it shuts down. do you think there is a chance there is a short in the port itself making it so that the battery drains itself? I left it charging overnight with no luck. What to do next? remove the port entirely while I wait for the new usb daughter board to come in the mail?

I think it's more likely that the broken USB tab is causing either a short or has broken a connection the phone expects, which fools the circuitry into thinking the phone is plugged in to USB, which won't allow it to charge via Qi. You could try charging it with the daughterboard removed, but I'd be surprised if it works. Hopefully you have a back-up phone while you wait for the part, even if it's a RAZR V3 or Nokia 3310. SIM won't match, obviously, but you can probably pick up an adapter locally.

That makes sense. I do have an old samsung tmobile phone that lasts about 4 hours on its battery. I guess I might be using that for a few days. I'ts at home though and I'm at work. It would be nice if this thing would just work. I need to find a t5 torx wrench and scew it up more......

Some advice for someone who hasn't taken this phone apart yet:
First, go to ifixit and familiarize yourself with the teardown guide. There are also some youtube videos that are helpful (if you can't find them immediately, look for screen replacement guides.
Second, you'll need something thin and flat, and hopefully not with sharp edges. They make tools for this, but I doubt you'll be willing to order them and wait. Myself, I used the nail file from a keychain Swiss Army Knife. It's possible, even likely you'll cosmetically damage the plastic up a bit. If you have a hair drier (or even a heat gun), this can aid in softening up the adhesive. In any case, go slowly.
Do the disassembly over a fluffy towel. There are many tiny screws, and a fluffy towel will trap them rather than having them bounce away and disappear.
As I write this, another thought occurs to me. If you can, wait a few more days, but order yourself a new battery off eBay. Many sellers include the needed disassembly tools (including a T5 TORX, small Philips, and the plastic separating tools). Your Nexus 4 is probably 1.5-2.5 years old by now, which means your battery has had well over 500 cycles. At this point, you've lost upwards of 20% your battery's original capacity. Or don't wait, but order a new battery anyway and reopen the phone when you get it. The degradation of a battery is slow and one really doesn't notice it until that day you think to yourself "it seems like it used to last longer". Indeed, you may open up your phone to discover a puffed-out battery in desperate need of replacement anyway.

Cool. I did end up ordering a new battery because of just that thought. It will be coming Friday though so I might not want to wait. I'll probably end up opening it up twice.. I also happened to open the phone about a 3 weeks after I bought it as somehow the screen cracked. I also have a heatgun. The phone is pretty old. I got it on release.
