What does it mean when your portable charger is blinking blue? The charger senses this battery condition and as part of it's features gives the blinking indication to say cannot charge this battery. ... A steady charge light usually means that the battery is charging and a blinking light shows that it is charged.

Try a different battery charger.
Maybe you are using a battery charger of a phone.
They have the same plug but different Amperage.
Usually tablets have more powerful battery charger than phones (2.1A instead of 0.5/1A).

The battery charger that you are currently using seems to have enough power just to keep your tablet alive, but not enough to charge it.

You can check on the data written on the battery charger's body the maximum amperage.

Charge the phone at least overnite. Sometimes a replacement phone may arrive with a totally dead battery and the charger may not be able to put out enough current to operate the phone and charge it at the same time. If you want it to charge faster use a plug in charger with an output rating of 2 amps. They usually have 2 USB outputs and can charge two devices at the same time. If you only charge one device it's a piece of cake for the charger. .

Hi,
FOr changing the charging port you have to take it to an authorized service center. it could be a software issue also.

Hi let me introduce my self, I am (BRYAN).

to solve this problem. Remove battery from phone keep aside then connect charger to phone and power on let the phone display a battery with an ! mark over it then remove charger and replace battery and switch on. You are done. ([email protected])

When you point your mouse into the battery icon sometime it shows that it is not charging, kindly try to monitor it as it will eventually change into charging mode.

- normally this happens when the battery is fully drained.

I really don't have any idea as to what you're talking about here other than a battery and maybe a charger. Seems as if you're saying that you have a 12 volt 1.5 amp automatic battery charger connected to a 12 volt, 8.5amph battery but the red light on your charger is blinking. The blinking red light indicates that the charger is not seeing a proper connection such as crossed polarity connection or simply a poor connection. You say that the battery voltage has dropped from 12.5 volts to 9.1 volts with the charger connected. If this is the case, the battery is badly discharged and the charger is not charging the battery for some reason. The charger may be bad but check the connections to make certain they are correct and good. If they are, I'd replace the charger.

Good luck
Steve

buy another battery

When my phone is connected to the charger, it says fully charged. But as soon as I disconnect the charger, the battery shows empty. When I connect the phone to the charger, it starts charging but after 10 seconds it says fully charged.
