Does this mean your phone is inside some kind of closed bag? This won't work unless it is cold outside. A permanently active display will produce a lot of heat. OsmAnd's offline rendering will produce additional heat. This heat will accumulate inside the bag.
This problem is not specific to OsmAnd. You should encounter the same overheating sooner or later with other apps when having the display permanently on.
Your Caterpillar CAT S60 shouldn't need a closed bag since it is waterproof. A simple bicycle mounting should be enough.

Hi,
I have an issue with overheating during navigation. (Phone type: Caterpillar CAT S60)
I was using Osmand on my bicycle in the bicycle navigation mode with offline map. After approximately half an hour of navigation I took my phone out of the bracket and noticed that it was extremely hot. On the screen was a warning message like "battery overheat, try to close applications". (Unfortunately I did not take a screenshot). I have not had this issue with other applications up to now (I have this phone for a year now). (I also repeated bicycle navigation with my old Samsung Xcover3 and did not detect overheat problems with it.)
The Caterpillar CAT S60 has a very bright display and I switched brightness to the maximum to be able to read it during cycling. When I looked at the battery usage it told me that Osmand and the display took most battery up to now (osmand 3% of battery capacity, display 3% of battery capacity during this half an hour after start (all the other applications had 1% or less). After overheat I restarted my phone, switched display to lowest brightness and later even switched the display off completely. The phone still got warm, but there was no overheat ing any more.
I think the combination of power drain of the display and the power drain of the graphic calculation of osmand were too much for the battery. Unfortunately I need maximum brightness to be able to read the phone trough the cover of the bicycle bracket. Is there a way to reduce power usage of the navigation, at least in bicycle mode? For example I would like to reduce the frequency of position updates (since I am quite slow a lower update frequency of the screen would be acceptable).
Could you add an option in the properties like "adjust position update frequency" (e.g. update every 2 sec / every 5 sec)?
My data: Phone: Caterpillar CAT S60 Android Version 6.0.1 OsmAnd 3.0.4 map: "Deutschland Bayern(01.08.2017)" (on SDCard)
Thanks for your help. Best regards, fatalbiker
