[Q] charging?

i have noticed twice in the last week that when i take my phone off charge in the morning it has been dead... like it was never charging. is this a faulty device or is it common for everyone

doesn't sound right. check whats eating up the battery at night, might be a dodgy app but sounds like a dodgy battery

Sometimes if it's using a lot of power it will be drawing more than the charger gives and still use up the battery. Make sure there aren't any programs running or large amounts of data being transferred on data networks.
It's really bad to run the battery all the way down. If you can't figure out what it is, it may be worth sending it in for service/replacement.

That happens to me with bricked kernel, are u using it?

Id suspect faulty usb/ charger if they move ever so slightly on worn bad cords itl drop charge even tho it was chsrging when u set it down for the night
I know.i have about 5 extra chargers two of them do this everytime
Suspect a charger before u suspect a 600$ phone

okay, i have an update.. this is freaking weird. i have a video and picture of this for proof. the phone was sitting on my desk with the screen off unplugged from the charger.. and then the screen and charging light come on, followed by a beep, and sure enough the charging animation was there... but the phone wasnt plugged in.. i started playing with it and a message popped up saying the phone is using more power than the charger can discharge... 'BUT YOUR NOT PLUGGED IN' :S
i will take it back tomorrow and try for my 5th faultless phone :S sigh*

Has anyone else had an issue like the following
1. phone is off (0%)
2. Plugin charger
3. Red light activates (charging while off)
4. Random amount of time passes eg. 30 mins phone boots up by itself
???
Can anyone explain?
is the phone faulty or charger maybe the cause?

Your not really supposed to run the battery down to zero. It could be designed to boot automatically if the battery had been below a certain amount and it turned off due to that... Not that i have anything to back that theory up...

A Possible cause could be damaged usb port (charging port). Get it to service center.

Screen Flickering & Not Charging

I having a problem with my Note 8. I mostly use it for work and the battery went dry and I was going to charge it but, when I plugged it in and did not want to charge and the screen was flickering. When plugged in the battery icon appears like its charging but then the Note turns on then the screen starts to flicker. Can this be a battery or screen issue? If anybody else is having this problem or have a solution please let me know. I do not want to send it in to Samsung since its rooted and probably they will not want to fix it.
Thank You
=SOLVED=---------
So it turns out it was just the usb cable. I found the original charger and worked. It charged the tab.

Same happened to when I first bought mine. I believe only healthy charging method is using a charger.

[Q] Galaxy Nexus i9250 problem.

Hey everyone. I have huge problem with my Galaxy Nexus i9250 for few days now.
Let me start from beggining.
First it was showing charging symbol even if it ain't plugged in. Then it stopped after I cleaned charging port.
Few weeks back there were great floods in my region (Bosnia) and we were in lack of electricity so I started to charge it on a car charger and after it's completely charged (2h) as soon as I start to use it the battery goes off really fast, example, if I use it for let's say calls or even on "stand by" after 30mins the battery goes for like 40%. That's when problems started to begin. If it was turned off becuase of lack of battery I had to turn it on by pressing "Down volume + power" for first 2 times. Then I had to remove battery for few seconds then put it back not completely but I had to press the battery against those 4 pins which conduct electricity to a cell phone and press those two buttons for like 30 seconds to turn it on. Few days ago, I had same problem, but this time it wasnt empty on battery, it was in my pocked with almost 50% of battery when I took it and I saw it was off. Tried again that same proccedure, it turned on, showed recovery menu and it turned off. Ever since I can't turn it on, it charges, but it doesn't show charging indicator on my screen. When I put my battery in other phone it shows it's fully charged. I can't turn it on, my PC won't reconize it, let's say it's dead. I don't know what's happening, so I'm asking here if anyone knows what to do. Thanks to all.

sounds like a battery + charger issue

You must verify the voltage output of the car adapter you were using with the phone , remember that the fact it has a micro USB does not mean its designed to the specs of your phone, sounds like the battery went berserk after it was charged with that car adapter ... you should not tinker more with the phone and get a new battery and the original charger for it , if you can or are able to ...

Thank you Frank. I already tought nobody will reply to this. So you think if I buy new battery and charger cell phone will start to work?
Car charger was combined, USB cable from Nokia and car adapter is for let's say every cell phone. I have original Samsung Nexus wall charger I got with that cell phone and it charges the battery it just wont turn on the phone. Either PC doesnt want to reconize it, tried with Device Manager to see if is there anything but no. Thank you again for your reply.

Still no luck! Does anyone have something to suggest?

Hmmmm .... still would go for battery malfunction !

you say it charges the battery ? if you are able to see the white icon of the battery charging when the phone is off and you connect the charger , then it's definitely the phone battery .... replace it and lets hope it works out

No, I'm unable to see battery charging indicator. But when I lick the battery you can feel the electricity. Yea, it's stupid method but it does the job. And when I put it in another phone it says it's almost full 99% to be exact. So battery... Gonna buy a new one.

Alright, i have been sailing in the same boat, my i9250 has not been charging for quite some time.
Now for all most few months the phone is charging without any problem. I suspect the Google Search application could be the reason. I uninstalled all the Google Search application update and kept it to the one come by default. Since then i am able to charge my phone without any problem. The Google search version that i have is V 2.2.9.542574.
Try it out. All the best!!

Yeah i didnt even got the solution yet .But i notice that problem doesn't occur when charging through pc but it charges slowly.I also tried factory reset and even battery calliberation but nothing happened.i will take my phone to care...

HTC desire 816, ! mark while charging.
Experiencing same issue. Tried different charger, no help.
I dont prefer pc charging as its slow and phone discharges quickly.
Any workaround or any solution?

Sounds like some fault in the battery circuit that is limiting charging current. I think a PC uses anywhere from 100 mA to 500 mA but a charger or USB port wired to AC outlet can use 1 A or more. I wonder if advanced wiping of cache and formatting internal data would reset it?

are you using Customized ROM or Stock..?

Did you ever figure out a solution to this issue? My phone is doing this exact same thing and it's super irritating.
I bought a new battery to try replacing it and see if that helps, but I am not a phone tech and don't know about taking the back off of this phone to replace the battery. Hoping someone might have a different solution or at least tell me that changing the battery will in fact help (and then I'll go to the trouble of doing it).
ETA: My phone hasn't been rooted or anything. Was working completely fine. Still works fine except for this charging issue.

It's not that hard to remove the back cover. The plastic is very durable so you can't really break anything. I think there is a youtube video and a few descriptions here on xda. Basically you start @ the SDcard slot using some sort of pry tool to pop the plastic cover off as you go around the phone. Just beware that they use a lot of sticky tape on the bottom half of the phone so it takes a bit more effort to get the cover off. I used old credit cards for my pry tool. Some cut up into strips and other time a whole card to break the sticky tape connection.

Charging Problem
i am having same issue since last day....
i tried full wipe and installed a new ROM and it still having the same issue....
i m out of warranty and any way to fix this issue other than HTC official service..?

I have the same problem. Did anyone find a solution? Would a battery replacement solve this frustrating problem?

Zenfone 2 Won't turn ON Or Charge. just vibrates every few minutes! Pls help

I had 7% battery and was on call, phone had shutdown suddenly and won't turn on or CHARGE.
When I press power button it just vibrates Twice. I had connected charger but it won't charge.
Besides it vibrates continuously every few (2-3) minutes (even without doing anything.).
I tried the following.
1). Charged overnight and tried on....Didnt work.
2). Opened the back panel and removed battery to mother board connection few times and connected back......it just vibrates . that's it
Pls help! Its out of warranty.

Let me know hoe it goes, because Im having the exact issue. I tried the steps from sukhwant717, but getting stopped at the step when it goes to the OS. Will keep my phone to charge for a few hours. I observe, that there is no heating up (battery), but will keep it for charging anyways.
Cheers

Thanks man....I did actually fix the phone...your awesome.....
It went something like this...
First phone refused to turn on....no charging light notification..it keeps vibrating.
Even @sukhwant717 method stopped at "os" thing.
After exhausting all option taken to a local service person who did something and told phones dead.
After coming home I have checked He RIPPED /SNAPPED ANTENNA cable.
I didn't bother much as phone was prononced dead!
After 30 to 40 days was casually reading @sukhwant717 thread and thought of trying again. I coonected charger and SUDDENLY I SAW ASUS BOOT SCREEN and phone was showing BATTERY WITH QUESTION MARK. I let it charge for sometime suddenly bootloader screen appeared but was not entering into recovery.(perhaps damaged bootloader , recovery).
Then I followed sukhwant717 method flashed bootloader and RAW image using ADB.
and phone RESURRECTED but with very low siganl.
It's due to RIPPED antenna cable.
And was getting good reception on 2nd SIM (perhaps uses different antenna/cable)
So I decided to order new Antenna Flex Cable but it's not available in India. So I went to ASUS SERVICE CENTER (near Brandfactory) in Hyderabad
and asked them the cost of Flex Cable, they said they won't sell spares...I have to RMA.
So I did and after two days I have received a call from them that "ITS FAULTY MOTHERBOARD" and will cost 11000 INR (USD 170, seriously ASUS),I said I rather want my phone in previous condition. I even told them to fix antenna cable ...I will manage.
They said their "TESTING SOFTWARE " failing device test even after connecting antenna cable.so they can't sell a part for a TEST FAILED device.
I told them it's because I had unlocked bootloader..the test is failing.they didn't have a clue abt bootloader unlcoking.
So again went to local market for the cable found A cable (though lil longer) and got it fixed for about 300INR ($5).
and got back the reception and typing with LTE connection on ZF2.
Thanks again @sukhwant717 ...
My observations: the issue could be due to
1) it's battery related issue (completely drained bir failed battery)
2) damaged bootloader
The people who have similar problem should leave the phone uncharged for 30 to 40 days even more and connect the charger and see if u see battery with ? Mark.
Or if new battery is available change battery and check....

if you need antenna cable i can send you. but before that. send me pics of motherboard where antenna connector sits. don't ever believe local and service center guys. they are dumb enough to ruin things.

I had a similar problem, phone suddenly powered itself off and started vibrating. With the phone off and connecting the charger it started to charge, but after a while it started vibrating and overheating. I did a factory reset but the problem persisted. I flashed the raw firmware and it behaved properly for a while, but a few days ago the phone died. It does not turn on, does not charge, screen never turns on, no notification light, no vibration. But if connected to the charger it gets hot.

Left the mobile alone and tried to plug in after 35 days, IT WORKED. At first nothing happened but left it in charge for few hours. Later the mobile came back to life when I tried to turn it on..... 3 days in and still working just like it used to.... will have to take care not to let the battery drain below 20%

I am having same issue .. did you get it resolved ? Any luck ?

hello i'm having the same problem
will this method ensure that my data won't be lost?
