Powercore 10000 suddenly stops during charging the cell phone

#1

I have purchased a PowerCore 10000 A1266 yesterday. When I’m charging my Galaxy J5, the charging stops in a random time before the phone is actually 100% charged.
I didn’t expect such an issue with a newly purchased device especially from Anker!
What could be the problem and what should I do?

Could you use a different cable and see if it still happens?

#3

Ok, but just to mention: I am using the original Anker cable and this didn’t happen in the first full charging of the phone.

Hi @dagixur,
Does it occur when you’re phone is almost done (for example, at 90% or higher)? It could be that your phone draws so little power that the power bank “thinks” it is done charging.
Feel free to reach out to support@anker.com with your order number and they’ll be happy to help you further if the PowerCore is defective.

Thank you for the hints.
Once it happened at about 77% charge and the next time was at 92%.
Is this something that I should expect a repair for or it could be considered normal?

Yeah. I’ve had Anker supplies cables fail on me before but I’ve got a few here so I just swap them to make sure it’s not the device that’s broken.

Anker supplied cables are usually good but I find the supplied cables aren’t as good as the cables they sale. I have a shorty cable that came with one of my devices and its already failing. But my regular cables are almost 2 years and still look and act like new ones.

I would try other cables and then reach out to support with what you have tried already. This will speed up the troubleshooting process for them.

Definitely try a different cable. Do you also have a different powerbank you can try? Maybe borrow a friend’s? Also, how old is your J5? I used to have an Oppo which developed a problem with “battery memory” - it simply refused to charge to 100% - but that shouldn’t happen with a newer phone. You could try a battery calibration app, there are dozens on the Play Store.

Thank you all for giving suggestions
Today I fully charged my cell phone with the same Anker cable and the problem (the charging being stopped before 100%) didn’t happen again.
This time, the difference was that, unlike the other time, I was occasionally using my cell phone during charging.
I will keep posting any new/helpful finding/observations about this issue here.
@tonicboy : My J5 is the first release (I guess 2015) of J5 series.
