Bonjour, suite à la dernière mise à jour système environ 15 jours, je n' ai plus les bandeaux rouges qui alertaient le niveau de batterie faible .
Yes that comes when Battery Saver gets turned on automatically at low battery level like at 15%.
After Android Pie update those red lines are not there anymore but a small red + comes in Battery Icon on top right.
You can go to Settings>Battery>Battery Saver>Ensure "Turn on automatically" is On and set percentage to 15% or 20% as you want.
It looks like you're new here. If you want to get involved, click one of these buttons!
