First of all thank you Osmands for your support!
Lodrog must be a happy one: Having on hand several smartphones and several
powerbanks for testing purposes. I am not a happy one.
Please try to enrich your knowledge, because there a many websites on the
web concerned with testing of USB charging cables showing very variing
resistances and therefore different charging results. And among the pour
performing USB charging cables not only those low cost ones.
I tested BatteryBot and Ampere and will continue with Ampere as for me the
more intuitive one.
And now last and the least. Playing around with the settings of my
Samsung S21. I came to the menu point for "Akku" (please let me use these
words, because I am on a german install). The way this item is shown in
the menue I would never image to find a second level menue beneath.
I tried clicking on "Akku". And what a miracle another menue opened.
And among other item I found "more settings for Akku"
And among that:
"Charging":
with more items "in german":
Schnellladen, Superschnellladen,schnelles induktives Laden.
I selected all of them, even not knowing why.
And after this selection my S21 is adding battery charge when connected to
my powerbank even when running OSMANd with navigating and recording
simultaneously . What never happened before.
Happy. Will be biking on the Gardalake in May.
