Need help charging problem

when i connect the normal charger to the phone, the charging light appears and the phone does not charges! on USB to laptop its ok, the phone charges , but on normal charger it does not charge...
any ideas???

I'd say the problem's most probably with the charger. Try using a different one to see it the problem still persists.

but why does the charging light is on ? and the phone says it's charging... ?

Its definitely a problem with the charger. One loose connection and it all goes hay wire!!
The light stays on because some current IS going through to the phone....

Yes, sounds like the charger.
As a side note, I have an external power pack, and if I plug it into the phone (power pack switched off), the charging icon appears - just on the DHD, not on other phones/ipods. I have learnt to live with this as a minor anomaly of the power pack, but just goes to show that the charging logic is not particularly clear

dhussa said it. The charging light might still be functioning because of some little current going through.. although that might not be enough to charge the phone.
Just try a different charger to ensure that we are thinking in the right direction. If the different charger works it'll eliminate the possibility that there's something wrong with your phone. (Although I doubt it since it is charging via USB.)

yeah...well i still hope it's a software bug :-s since a saw a similar thread and a good battery calibration might just be the cause
oh well...thx guys ...

[Q] battery problem :-/

hey guys, I noticed a problem about the recharging time after updated LG optimus g to kitkat. now it takes really long hours to charge the phone completely, for example it needs at least 7-8 hours or even more. how can I solve this problem?

I have this problem. Anyone knows something about this?

You should try too calibrate your battery
I'd recommend to use NEMA BATTERY CALIBRATION

I also have a problem with my LG Optimus G. I have Android KitKat, software 20C, rooted phone. Yesterday my phone battery dropped to 0%. I was sick and I didn't have time to charge it. Today I plug my charger but nothing happens. LED isn't working (no red colour), there is nothing on my smartphone display. What's the problem with this smartphone, I hope he isn't bricked.

I had the same problem, turns out it was just my charger. After I bought a new one the charging time droped from 7h to 2h.

I have the same problem. I can confirm that the problem is the charger or the charging port or the usb cable socket.

im also starting to notice my phone is charging so slow, the battery icon indicates that it's filling up but sometimes the percentage wont go up, it will be stuck at 50% for couple of hours, and i have read some topics saying that This phone has really some problem burning up the charging ports, one even said that he already burned 4 chargers out of this phone is this true?

No, it's not. Just change the USB cable. If didn't help change the battery. I myself did it vice versa!

i think it's my charger, because i tried my friend's charger from his Zenfone 5 and it charged my phone for just about 2hrs or so.
mine would charge for atleast 3 to 5% and after that it will not charge anymore, i wonder what happened? I am on full stock right now fully unrooted using LG flash tool. it's really a shame that my charger gave up so soon as i have only bought this phone(Brand New) not 2 months ago.

I had exactly the same problem. I forced them to change my main board under guarantee. It didn't help. I bought a new battery. Helped but charging time was 3 hours. I saw I couldn't transfer files via USB tried changing cable and I can charge 0 to 100 in 2:10 hours. 20 mins faster than the day I bought my phone. The stock charger is OK but the cable is a crap. Do what I did from bottom to top!

Are you using stock charger to charge online? there might be one more possibility that battery might not be pinned properly to the phone.

yes i am using stock charger , and i tried several times battery is pinned properly .. it all started because the computer guy made wrong usb connections on my computers motherboard .. i connected to transfer my photos and it suddenly died. on connecting to computer via usb it charges sometimes ..but then restarting it results in mega drop in battery level and then it wont charge.
Just wanted to know that if this is a hardware issue or a software issue. would flashing a ftf solve the issue ?

K i personally think that there is a problem with the battery. once the battery is connected to wrong polarity it generally get ****ed up but i see that it charges properly with the battery charger. if the charge is retained normally there is definitely no problem in battery. It will be the PIN . But not harm in trying to reset through PCC or flashing FTF.

ok i will check one thing tonight .. am gonna charge the battery and leave it over night .. if charge retains and acts normal i guess pin and everything else has to be fine .. then the only thing fishy would be when connecting a charger...

Does Kernel affects charging or mess it up ??

Yea it does. Get back to stock charge your battery use the phone. if the battery drains normally. There is no problem with battery. The problem is with pin configuration of the phone.

I'm not sure its safer to check it with the new charger first in order to avoid Any problem. Other wise you can check the charger with some other phone

Not Charging - Phone is Dead

I have a Zenfone 2 551, 2GB/16GB. Bought it 45 days ago. I bought an Asus Fast Charger later on. The first time I wanted to use the new fast charger the phone turned off.
I change to a regular charger and the led turned on (I had 40% battery at the time). Left the phone charging (standard original Asus Charger) and the battery instead of charging is loosing charge. Even with the led turned on.
Eventually the battery died. I tried other chargers. 1 out 10, maybe a got the led back on, but the battery stayed on 0% and wasn't enough to even turn on the phone
I've read several people having this same issue.

http://forums.androidcentral.com/asus-zenfone-2/552432-phone-not-charging.html
In one of the post someone wrote this tip
Thanks for the reply. But after a long day of stressing, it worked by itself. I read from an article about another android with quick charging that the USB could have not been all the way in in the adapter which, in my opinion, it was but regardless I repeatedly unplug and plug(15 mins -30 mins interval)... did the same with the phone plug and unplug till I saw the battery level going up
It didn't worked for me!
I've already tried:
a. Changing chargers and cables
b. Pressing power for 20 seconds
c. Pressing volume up + power
d. Plugging and unplugging the phone every 15 minutes
I bought the phone while visiting the US (I don't live there).
Has anyone else had this kind of problem, and was able to fix it?
Thanks

Can you confirm if the ASUS adapters/USB cables work with other USB devices? Have you tried charging from a PC? If so, unfortunately this issue sounds like a hardware related issue and will require sending on for warranty service. Please feel free to contact me direct at [email protected] if you have any questions or concerns.
Sincerely,
ASUS_USA

my phone died yesterday like that. i connect my phone to my computer with Asus usb cable the one comes with phone. my phone screen cracked about 1 month ago but it was not disturbing me so i didn't repaired it. right now nothing works on the phone.. at the moment i connect my phone it turned off and for 1 sec battery screen appaired then nothing. can't see my phone when i connect to pc with adb or something like that too so i think problem is more then screen but any idea ? @Asus_USA @Asus

The guy uses a metal tip pin to release the battery connector? seems that is risky and may short something out. These asus phones have so many issues, that's for sure.

Despite replacing USB power board & Sim/Microsd holder still cannot get charge

Hi guys
Just cannot seem to get the thing to charge.
Tried different charger/usb cable. Got completely new USB power board. Sometimes the battery icon comes up on the screen when i turn it on of just a battery with a bit of low red at the bottom of it. It won't turn on. Theres not even a charging beacon light on top of the phone to indicate charge.
What does this usually show? Bricked phone, bad motherboard or bad battery?
Cheers.

Is the error that comes to screen
"USB not supported"?

not getting any error mate. It is totally dead.
I did buy a new battery which had 4% life left. Not enough to copy 64GB data to an SD card.
It seems it must be the main board which is damaged. I have replaced the power board and the middle ribbon cable. This has to be a mobo issue unless u can think of anything else?

I still don't think that's mobo issue. Try this before you intend to replace your mobo.
Plug in charging using any charger other than wall charger. Use a power bank or anything and when the battery icon shows up that you described in first post(the red icon) leave it there as it is and let it charge over night. Try powering up in the morning.

I dont get any icon on the screen when I plug a charger in. Even the powerbank... When i plug that in I get no beacon light on the top of the phone to indicate charge and also no icon on the phone screen. The phone never gets hot when it charges and the charging device never gets hot. Stone cold both of them.
What do you reckon?

I think your phone needs a doctor ?. Take him to the hospital (service center). Last resort before going to service center is take the battery out and charge it using one of those battery charger.
