Battery Discharge Quickly Overnight - not happened before

I have a forerunner 955 solar, had it for a couple of weeks - no issues until this morning. Battery been great. I charged a day or so ago, looked this morning and the battery was at 47%. It was not connected to the Garman app and would not, i had to restart the watch - related? Will see if this solved the issue. Is there a fix for this?

I did install the IQ app yesterday, i made no changes though other than synching with the watch anything to do with it?

Reading other threads, i see the picture below. Looks like a graph showing discharge since last charge. Can you tell me where to look for this please, also nothing in the instructions?

Thanks

Hi there..

What app are you using to display this battery usage?

I do not know, it was taken from another post.

It is Battery Graph by Cheurch. Really nice app. For me, it predicts the remaining battery time even better than official Garmin prediction.

Perfect, we have a winner - thank you.

And regarding the graph - the app has no settings, you need to wait, until more data are gathered, then you will see up to 4 weeks of historic data. You will then be able to change the view using the UP and DOWN buttons.

There is a description of how to use the app in its page In Connect IQ

The same problem after previous update (after previous update a few weeks ago, before 17.24). 10% discharge in 15hours. Before it was like 3-5% for a full day!

955 (non solar)

This is a known issue, the watch needs an extra restart (holding LIGHT for 15s) after the update, otherwise it sometimes drains the battery. I don't know why Garmin does not have this in the official update instructions.

Thanks. I'll try and leave a remark tomorrow.
