Osmand on Samsung with POwerbank support

[fixifoxy]

I am using OSmand for bike navigating. I bought a powerbank to have  enough battery support for longlasting  tripps.

When using the powerbank standalone to charge the smartphone, charging is running ok.

But when I am navigating with Osmand and plug the powerbank in, I get the plugin sound, and the icon is shown on the top of the screen. But it seems as if the smartphone is not able to use the power of the powerbank. The percentage of the capacity is running down instead of holding the state or even showing an add of capacity.

Anybody  any hint or experience?

from a technical point of view this does not make sense. repeat the test with an other different model of power bank to the samsung and with the existing your power bank repeat this test to an other smartphone. After those 2 tests you will find what is wrong.

Use BatteryBot Pro (in f-droid) and see what the time interval is for
each % of capacity, with the powerbank and without.

It may be that the phone is using so much power that it's more than the
delivered charging current.

Also, some chargers are only the 500 mA USB spec, and some are more, and
detect devices that can handle more in various ways, all a bit messy.

However, I can tell you that on various phones over the years, being
plugged into a car charger (Anker lighter socket usually), the charger
was able to produce a net charge. The exception was all of:

- very hot temperature
- running osmand for an hour solidly
- no cellular service

(which is I-70 in Utah for the curious).

You can also test Ampere (braintrapp) which shows charging / discharging in mA

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.

 it is not right to make fun of people who try to help us

Hi, I apology, having you informed  that some changes in the "AKKU" settings solved my problems with the battery charging. No, after some tests, let me say I was wrong.

Now I am  running a powerful Powerbank (total output 20W). And thats it.
