So my ET4G wont charge the batt. but will connect to everything else just fine

So not 100% sure as to why this happed, but I did bring it to the sprint store they told me there was some corrosion found in the charging port. Which in means there unwilling to even look at my ET4G luck has it I did get the ins. coverage...But I'm not ready to just roll over and give up that easily. What i find strange is that I have absolutely no problems connecting!? I can flash with Odin/mount usb/SD card and usb tethering.???? When I plug my phone in it will start charging then in less then a min it stops...if I check the battery info page it will change from discharging to charging for just a short time when connected to power (usb or charger) then goes to not charging...After downloading and testing (one at a time) a few battery apps found in the market I noticed that my battery temp is reading at 6C and when I'm really using it and its pretty hot to touch the highest reading I've gotten is 13C now I don't know what translates into as far as F but I know that its way to low to be correct...So I figured I'd get the possibility for it being a software issue outta the way by flashing back to stock and trying a few combos of Roms and kernels making sure to wipe and keep the Roms absolutely as they came unless I needed to add gapps...I quickly got an error upon plugging in stating "charging stopped battery temp to low." and every touchwiz based ROM I use gives me the same error...So I've come to the conclusion that I somehow got my phone damp/wet and fried the temp sensor...So unless I can replace that for cheaper then 100$ fixing the hardware is useless but
I was mostly interested in what apk/receiver is responsible for telling my OS to not accept the charge b/c its to cold and if I can just disable it in autostart manager or if theres another work around to force my battery to take the charge (I know there is a probably gonna be a risk of over charging/over heating etc etc etc but either way I'm gonna end up dishing out the 100.00 due to the pure inconvenience)
**I should also note I have tried 2 OEM chargers 1 after market car charger 2 OEM batteries and 6 different (two different brands) of after market batteries all of them work for other ET4g's and all of the batteries will take a good clean 100% charge from a wall charger or in my wifes ET4G....
Of course if theres no fix which I'd find hard to believe said phone might just end up at the bottom of a a lake...if sprint will still honor there replacement police in that case????
I'd like to use the "lake" phone as mod fodder for our current Emmc issue once we get a "possible fix"not just a random shot in the dark, but if we get what is believe to be a fix I'll be happy to follow a Dev's step by step instructions, and log my findings to help out! With that being said thank you for taking the time to read my monster of a post, and any advise into this issue is much appreciated

I would also like to know if there is anyway to fix this problem...
My wife, being 36 weeks pregnant is kinda forgetful suddenly.
She lost her phone for about a week we searched everywhere, cleaned the house many times, cleaned out the car, search for a week.
the amazing thing is she lost it walking from the bed room to the car, she was in the car when she realized it was missing maybe 2-3 minutes after leaving... long story short...
I went walking and found it on the side of the road... a week later with the case and battery cover off laying face down on the grass. I got it home took it apart, dried it out, and amazingly it still works the only thing wrong with it is the Battery saying its at 6°F and wont charge, Its stock ive tried factory reset didn't work. I have the same phone i can charge the battery in my phone but cant charge either battery's in her phone.
Would there be a way to fake the sensor?
Force it to say a higher number?

That's what I had to do... clean the contacts with rubbing alcohol and something that can get into the port and remove any debris - a cotton swab, towel, anything... then try again until it works.
Here's the pinout schematic:
http://pinoutsguide.com/PortableDevices/micro_usb_pinout.shtml
So it's possible to have one and not the other if contact is not being made.

I had to go as far add cleaning all the way up the main board and all every contact point from port to battery

If the phone works just fine go on eBay and grab an external charger and spare battery. I got one for $8 with generic battery. Works great.

Here's the thing. This not working is a sign of other issues. If you see corrosion like this and you don't address it it will lead to bad things. Better to remove any corrosion while it's minor IMHO.

Just realized the OP here was from May, Wonder what happened. I was reading the second post about the phone on the side of the road thinking it was from the same person. In that case they are lucky it still works and any damage is likely done

Phone won't turn on :(

I've been experiencing some problems with charging and I read in out of the threads that I could use a bit of electrical contact cleaner and it would work. And now my screen protector is ruined and my phone won't fully turn on. It boots up, vibrates then it turns off. What do I do I'm freaking out right now. I'm going to put it rice to see if that works at all Anybody know what I should do I'm really scared right now.

Exactly what did you use? Link to the product.

Yea a little more detail on what you used would be very helpful.

Jesus I feel like the biggest idiot of life. You guy don't realize how F*cking stupid I am. After being in a complete rush I used the wrong type of cleaner. So After I soaked it in rice and took it out I actually used a proper Electrical Contact cleaner and and now everything is fine. But I am now certain that the cable is done because it wasn't charging or showing that it was plugged in so I used my friend's Blackberry cable and everything is fine. I'm so relieved right now.

Lol glad to hear that its fixed.... we all make mistakes

Thanks, the only problem I'm still back to is that it won't charge, which is what was happening before. I am not sure whether it is the charger itself or the micro-usb charging port (Which I could replace). Phone thinks it's charging with the lightning bolt in the top right, but it won't charge...if I go to battery in the settings it says discharging but in the charts it that it was charging all this time.

My friend has that bug with his evo... try another charger. It might help

I'm trying that right now. If it doesn't charge does that mean that the charging port is dead or could it mean that the battery is dead aswell?

Tbh I don't know but this is a educated guess.... seeing that it shows that its charging on the phone means that its receiving the charge. A good test would be to take out the battery and plug your phone into the charger. If it works that means that the port is OK and you'll need a new battery. If not then its the port. Hope this helps.

What do you mean by if it works, as in if the phone boots up and works normally when plugged in?

When you take out the battery and plug it in to the charger it should work normally as its getting power from the plug.

So I tried that and it wouldn't turn on. I opened up the housing and found some weird residue near the port. This is what I saw

What on earth is this crap?

Well that's odd..... idk

Meh whatever, I smelled and it was just the smell of the wrong cleaner I used, luckily it was just on the plastic parts so I'm safe, I disassembled the rest and found the charging port. I'm ordering a new one for $10 shipped from NJ and not from HK so I should get it soon. Thanks for your help btw. I really appreciate it. :good:

Good luck bud

Update: I just replaced charging port literally just now and it still won't charge. It still says "Charging" but it's not charging. In the Settings it says discharging.
Could it be the battery? I'm thinking of buying a new one and seeing if that works.

Updated Update: The 6% that had remained on my battery before I took my phone apart to repair it is now gone leaving the battery with 0% charge. But, I believe I may have found the problem! If the phone is unplugged from my charger and I try to turn it on it won't turn on at all. But if I plug it into my charger it will boot up past vibrate to the Nexus logo (The X) and then it dies out. I think that the problem is in the charger that has a input voltage drop so it's not charging enough to keep it going. I'm going to use my friend's Samsung Charger (From his Galaxy S II) to see if that will solve the problem.

[Q] Serious issues.

Okay, I have no idea what is wrong with this piece of ****. I'll go to where the issues started.
I got a brand new phone with insurance and flashed it over to Slimbean back in May, stayed on the same build with no issues, until about 2 weeks ago, when the issues started. The screen would stay off and I would have to pull the battery. It did this a lot.
Then out of nowhere, after a routine battery pull, it wouldn't come on at all. The blue light would just stay on when I tried to turn the phone on. The only way to get it to boot was to put the charger in then power it on.
I flashed back to EL29 and upgraded to stock GB27. The wakelock thing still happens. It randomly reboots. and now, the blue light of death thing is happening even when I plug the charger or usb in. I can't get it to respond at all. can someone help me? I figured flashing back to stock would help but apparently not...
EDIT: What is weird about the blue light thing is from what I've seen it is supposed to be a brick, but when it was happening before plugging a charger would fix it. Now it doesn't fix it.
edit 2: Just put it back on the charger, took the battery out, took it off the charger, and tried booting. It worked. I still need to know what is wrong so this stops happening, though.

Instead of getting all mad, why not just get a replacement phone?

Because I just got a new one and I don't have another $100 to spend. I shouldn't have to throw down more money.

If it's a factory defect, which you could easily argue, you shouldn't have to pay a deductible

Take it to a sprint store, have them test the issue, if no water damage and within a year of receiving the phone they should switch it out no deductible no hassle.

Also, try grabbing a logcat. It's possible there's a conflict with something causing the reboots and SOD. The blue brick light is odd though.

All phones replaced by isurance have a 1 year warranty from the time received through the isurance process. I have had 3 E4GT because of the power button and overheating issue and they will replace it if it's a factory defect. Just cause they replaced it doesn't mean you have to pay a deductible go to your nearest sprint repair center or call sprint and they should transfer you to the isurance department and they'll send you a replacement for your replacement. My last replacement took me 4 days to get here and it was during my power button issue which kept restarting my phone like every 5 minutes, so annoying.

This has happened twice to my phone, and both times, it turned out to be a battery issue. I take it sometimes when you plug charger in the battery charge icon doesn't show, but after popping it out and then back in it will show then boot? This is because your battery isn't completely blown, or even fat, rounded etc... But has a segment of bad cells. I'm sure when this happens your phone gets hot underneath the camera as well. I am dealing with this same issue, and awaiting a replacement battery yet again. Watch the phone discharge carefully. Mine discharges fine until about 80%, then does exactly what you are saying. After the battery pull and such, I get a boot. The battery by that time is around 62%. Works great until about 45%, then completely shuts off. If I boot back up, it says the battery is dead and I have about 3% to work with until I get a charger hooked up. I tried all the same stuff you are saying, and the battery replacement fixed it, for a while at least...
Edit: a side from the battery being crappy, I think I found the reason why it would do what it is doing. Mine did this yet again, even with new battery. Then I felt the spot that was heating up, and noticed it was extremely close to the micro SD card. Removed it and went through a full cycle without issue. Seems there is an issue reading my card, and was causing the phone to power off, and lock up, all the while tearing up my battery... Give it a shot, if you have an sd card in there, if not, I don't have any other suggestions besides take the phone back.

[SOLVED] RUGBY SMART - Not Charging and "No Battery" Issue

First of all, I apologize if I put this thread in the wrong place. All of the other Rugby Smart threads I've seen are in the Galaxy W section, so that is where I put this.
Anyway, my Rugby is having a charging issue. I have Kemonine's CM9 Beta 7 installed by the way, but this is only a recent problem. When I plug in my phone when it is turned on, it DOES charge, but my phone says "Not Charging". However, when my phone is OFF and I plug it in, it shows the green battery charging animation for maybe 15 seconds or so, then it shows me an icon with an empty battery and a yellow sign next to it which looks like it doesn't think I have a battery even installed in the phone, but I do.
What should I do to fix this, if there IS a fix?

Nice phone first of all, but going back to your query, and with the limited information presented here, all I can do is let out educated guesses and assumptions, they are classified as:
1- Battery might be dead, do check it (if it's bloated or depleting fast), and try to buy a new one if it is damaged.
2- The issue might be a ROM bug, which I assume isn't reproduced by anyone but you, unless anyone else reported it, then you are safe and rather the ROM needs some polishing. I believe formatting your phone or wiping partitions haven't helped you, as I would've gave them a shot in such a desperate case.
Okay, here's the final suggestion, and this one particularly happened to me on my GT-I9100. My phone had a charging issue, in which the battery indicator displays that the phone is clearly charging, although it is unplugged, and when I did plug it, it never showed it's charging. Also, when the phone was powered off and completely unplugged to the charger, the charging animation was displayed and that could eat up my battery. Now, here's the deal, when I mentioned the probable ROM issue, I wanted to know if it happened on stock firmware as well, since when it comes to me, it happened on stock. So, if you were convinced with the information above and partially matches your issue, the problem to such a phenomenon is the USB port (the port which allows you to connect to a PC and plug your phone to a charger), this piece of hardware is definitely corrupted ( at least in my case previously) and needs replacement. It gets ruined due to exposure to water or high voltages. It costs 20$ (the piece is 10$ and nobody works for free), so, better find someone who could replace it for you. Good luck in solving that issue fellow user, and I have no idea about the valid path for your thread.

I don't think the battery is the problem, because I can still charge it and use it, it's just the software that seems to be the issue. When I plug the phone into a source of power, like an outlet through a wall charger, the Battery menu in the Settings goes from saying nothing to literally saying "Not Charging", although when I lock the phone and turn the screen back on the lockscreen says it is charging.. So it does recognize that it is plugged in (so it can't be an issue with the micro-usb port on it), but for some reason it gives me that message. This isn't a major issue, just a slight annoyance. Maybe if it gets to be really bad, I'll either re-flash a ROM or boot the phone into Download Mode and just completely wipe everything and start over with ODIN tool if re-flashing doesn't solve the problem (I've had this ROM many times before wiping it and moing on to another ROM, and this issue never arose until recently so maybe a complete wipe of everything will fix it somehow). But thanks for your assistance
EDIT: I added some pictures for you to see. This one below is of the lockscreen saying it is charging:

This one is of the battery menu saying it is not charging:
And here is a video of the charging issue while the phone is off. Note that it does take a while for the green battery symbol to change to the no battery symbol, it doesn't happen until near the end of the video so if you want just skip ahead to maybe 2/3 of the way done and you'll have to wait less to see it.
Link to video on TinyPic
(Yes, this video is poor quality, the Rugby is pretty much the best camera/camcorder I have on me.)

All Safe Here
As I previously said, if you're experiencing the same and exact symptoms on stock firmware, then your problem is classified under "hardware". Yet, if this issue is only reproduced on this particular custom ROM you're using up there, then your phone is alright and unharmed, rather the ROM has an unnoticed bug which seems to have been never fixed by the respective developer of this device. It's more of an annoyance if you ask me, nothing critical though, and my issue was never near yours, not even close. Better live with that annoyance, or all what's left is finding a different ROM (you're using CM 9? I doubt that any dev would update that..). Good luck pal, do a nandroid backup just in case too

Lenovo Vibe Shot Z90-7 Charging Problem

Hello,
I would like some insight on a problem that I am having with a Lenovo Vibe Shot Z90.
I just bought the phone two months ago during a trip I took to Singapore. It worked fine for about a month before the problem started. The phone never fell down, into water, overheated or anything like that. The problem started suddenly, without an apparent reason. Alas, the local Lenovo branch refused to honor the warranty, claiming that they only take in "EU models".
The problem is that the phone will not charge while it is turned on. It does not even "see" the USB cable getting plugged in. If I turn it off however, it charges just fine, all the way up to 100%. I also noticed that the battery drains faster, for no apparent reason, without any apps running. It most definitely is not a software problem, I did a hard reset at first, it did not work and then, just to be sure, I even flashed the latest official ROM using QFIL.
Do you reckon there is any possibility that the problem is caused by the battery, or is it definitely mainboard-related? If there is any chance that replacing the battery will solve the problem, I could order one online and I am competent enough to replace it myself, but I do not want to get into an ordeal if there is not even a remote chance that it would fix the problem.
Any suggestions welcome.
Thank you in advance.

Yes. A bad charger was the first thing that I considered, so I tried another 2 A charger and then even tried it with a 50 A desktop PSU. It made no difference. There is no current flowing from the charger (PSU) to the phone at all once it is on. When I turn it off, it draws about 1.25 A, which is pretty normal.

You have to read about "USB PowerDelivery".
Alone PSU current efficiency has no effect on USB devices charging current.
Amount of current that the end device is able to absorb, is defined on the resistors (voltage dividers) which feeds the D+ and D- lines.

I am aware that the device would not ever (normally) draw more current than it is supposed to, regardless of the PSU used.
I did check some of the resistors at the time before my original post and they did seem to fall within spec. Besides, the phone would charge normally once powered down, so I doubt that it was such a simple problem as a resistor. Alas, this is an old thread and long ago I decided that the phone was not worth my time anymore, so I threw it away and thus I cannot recheck the circuit again. This will hopefully be helpful to people with similar problems in the future.

I think this is a software issue. Please tell me what version of ROM and baseband you have?
I was playing a lot with different roms, and in some cases I had the same issue. Eg when phone was chargeed from PC it was very slow.

Hi,
i've just received my lenovo vibe shot.
After a full charge, it worked perfectly.
After a second charge, still working. And the it stopped. No led when i plug it. No charge, no power.
I tried a different usb cable. Then another charger. Still nothing.
Any idea ?
Thank you.

As far I know, MAX77819 is charging the battery.
Using multimeter measure selected (PINK) test point and read if voltage vs GND is about 1.8V

Thank you for your answer.
I'm not sure I will open the phone now as it is under warranty.
I'm also not sure that i would be able to open the phone as I don't see how to open it !
It 's kind of weird that nobody else seems to have this kind of charging problem. Bad luck I guess.

Same problem
I have exactly the same problem. Phone was purchased from tinydeal. Replaced ROM with international version because not been able to run Facebook and other applications. Working perfect for 1 month. Then suddenly stoped charging. When plugged indicator shows charging but percentage charged droped.
I was not able to use warranty because I cannot send products with lithium batteries internationally using regular mail.
The phone was at two service shops. They problem is this chip which should be responsible for charging is very difficult to replace. They could not repair it. Now I have ordered a motherboard from aliexpress for 70$. When the phone broke there were no options for purchasing motherboard.

Thank you for your post.
I have now sent the phone back (i did send it with regular mail !). Still wainting for replacement.
I hope i won't have the same problem again !
Let us know if you succeded to fix the problem.

Hi.
I had the same problem after my first boot. I bought in Aliexpress. My solution was (more or less) easy.
I don't know why, powerful charger didn't work, but my old 5v-500mA worked 30 mins after connected. Once I had 10% battery I used stock charger and thats all.... very strange... Probably something wrong in battery..... who knows.... I hope this helps next time.
