HI I have a few questions. Anybody know the full time to charge the tablet to 100% capacity? Also I know the amber light means charging, and it turns off when complete. However has anyone else noticed that when it turns off if you press the power button briefly one time it stays lit white. Unplug the charger the light goes off but plug it in and light stays white. Is that normal? Is this a trickle charge mode or something?
Thanks
btw tablet is powered off when charging and not in sleep mode
When mine is done charging, the lite goes white and stays white till I unplug the charger. This is with the a500 turned off and charging though.
See my tablets light is orange when charging and goes out when done, battery is at 100%. I press it once while still pluged in it turns on to white. is the IC charging chip that regulates charging on my tablet out?
Today my phone chrashed twice when starting navigation while on the car charger. Screen went black, battery charging icon appeared, red led showed. A second attempt gave the same result. I also noticed the LED shining red... was rather afraid. And decided to restart without the charger, start navigation, and no crash.
After unplugging the charger, the screen stayed on the battery icon for a while. I could reboot the phone with the power button.
It woked okay a few times before but maybe the battery charge state was different, or I started navigation before plugging the charger in.
So, I won't use that charger (Samsung CAD300UBE rated at 5V 700mA) again. But why would it crash? The phone running on just charger power (which is insufficient) and crashing - perhaps to prevent damaging the battery with shallow charge cycles? I estimate the charge left when this happened at 80%.
So be careful which charger you use. Does anyone have a similar experience?
Im having same issue, but my phone wont boot up.
Any fix?
I was playing some games.. phone crashed. Now when i plug in the power the LED just flashes RED. Can't boot. I can still get into the bootloader but thats it.
I am rooted, unlocked, etc... am ****ting my pants right now. Any tips guys. Searched around the threads not sure what to do ? Maybe restore and RMA...:crying::crying:
actually now i cant even access fastboot... it shows for a split second and crashes out to blinking red LED
plug it in the wall, keep it ther for 10 minutes or so, then try to turn it on again.
This happens when your battery is literally out of charge.
Let it charge, the phone's entered the trickle charge mode because the battery is low. It may not recover and if it doesn't it means the battery is having an issue. From my reading of red light issues the solutions have been: let it charge because the battery is to low, it shorted so unplug and replug the battery, or to rma it cause the battery died.
Sorry guys skipped a boatload of details.... yeah the phone is charged...
I was playing games off the wall charger, believe me it has plenty of power. The light is blinking red can't do anything, no power up.
Either RMA or take the phone apart, disconnect the battery wires and reconnect them. There should be a guide somewhere, just look blinking red light of death.
Yup, blinking red led is a trickle charge mode.
Maybe the wall charger did not have enough power. Or the phone decided to discharge anyway.
What I am wondering about: if the phone gets back to life, is it empty or full (as in: switch it on without charging and see if it shuts off quickly).
Potential ways to handle this:
- wireless charger. The wireless charger does not pass through the 'red led' circuit but charges the battery directly.
- leave on trickle charge for a day. To trickle charge, that is supposed to be a slow process I think. Maybe someone can measure the current when it happens.
- unplug and replug the battery. This may reset the charge circuit or something.
- hold the power button down for 10 seconds. This will electronically disconnect the battery (but I do not know if it is a place that makes a difference).

This is a thread i created for all possible red led problems (4 in total)
. have a read... It should solve your problem
Hi everybody, My n4 seems to not charge correctly. When I plug it in my house the little lightning logo appear ( when on or off) but it doesnt charge the phone or sometimes only for like 2 minutes. But when it is plug into my car it charges. I have used multiple different charger ( N5, sgs5,s4,htc, blacberry, but it do the samething).
Note that when the lightning logo appear it doesnt say in charge in the notification panel nor in the battery stats app.
Do I have to change the battery or the charger port?
I had put my 1.5 year old redmi 3s prime for charging last night and gone to sleep, it had 4% charge and i woke up to find it was 16% and not charging. I then changed my charger and cable but no avail. I then cleaned the charging port to see if that was the problem still no use. I saw couple of youtube videos n then unplugged n re-plugged my battery to see if that was the issue but my phone wasnt turning on, so i left it for plugged to the charger a couple of hours more but it wasnt charging. Then i rebooted it into recovery (power + volume up) and ran a few tests for which i have attached the screenshot. I live in a place where there is no Redmi service centre so i have to fix it myself. I would like some help to figure out if its the battery or the charging port faulty.
Now when i try to turn of the phone the only thing i get is a red light blinking. Also I used a friends phone cable to charger my phone sometime back and now his cable isnt working as well.
