Hey everyone,
does anyone else have a 2. gen Anker Astro E5?
I started using one one month ago. It charges my FP1 up to about 70% without a problem. Afterwards, at about 80-85%, the charging constantly stops-restarts-stops-restarts, so that the red LED is blinking.
If I turn on the display (set to keep on while charging), this sometimes stops until 95-98%, and then the behaviour restarts until the battery is full.
When I use a generic USB cable (not the one coming with the external battery), the charging most of the time (around 4 out of 5 times) completely stops short above 70% battery capacity.
I wonder if this is FP-related, or the external battery is defective. The manufacturer, Anker, praises itself having developed an intelligent charging system, i.e. the battery is negotiating the energy to be delivered with the phone’s electronics.
I had this trouble from the start, and now contacted their service. They would replace it on warranty, but before doing so, I wanted to ask if anyone on the forum is using the same model and can tell if he/she has the same problem. I don’t want do produce more e-waste.
I also wonder if my phone’s battery could get damaged by the behaviour described. Any comments?
PS:
I haven’t been around much since, uh, August, I think. Hope to be more active again in the near future. But the future is an undiscovered country, so let’s see if this works out.
