On normal days , COVID-19 aside, I turn my phone off on flights ( the only times I can rest is the 2-3 hours at 35,000 feet. Then landing is a nightmare noisy startup jingle, combined with all the following messeges coming in. I ALWAYS forget to put my phone on silent before turning it off ... then putting a finger in the speaker to muffle it..
I searched for quite some time, could not find a solution. Obviously the other option is not to turn phone off and keep it on airplane mode, but I found those twice a day 'off' time is a life saving on my poor battery. I normally on two flights per day.. and driving rural areas kill the battery dead very easy.
Any solution ? TIA..
