Loving this trend of banning phones.
I overheard a conversation last week from a group of teachers talking about the phone ban:
They had students put their phone in signal blocking bags. But some phones kept searching for signal until they overheated… literally warping the phone screen.
Now they advise students to put it in airplane mode before sticking it in the bag…
- morkalork 2y agoI swear the LG G6 I had did this. When I visit family, it's a long drive through some pretty spotty areas and the phone would be hot to the touch and the battery drained faster than usual. As if it's just constantly screaming out into the RF void.
- hunter2_ 2y agoIf the closest tower is on the fringe of connectivity, and you've got an app that's acknowledging push notifications constantly or similar, then wouldn't it make sense that it has to scream constantly? Keep in mind that not every push on a data level results in something displaying in your notification tray; these are quite distinct despite the phrase "push notification" commonly being used for the combination of a push coming in and a notification being presented as a result. Maybe the faraday cage bag in GP's anecdote wasn't quite good enough, so the same thing (fringe connectivity combined with lots of Rx packets needing to be ACK'd) was occuring for both of you. When you are 100% out of range such that no Rx is occuring at all, then at that point yes the phone should not be screaming into the void often enough to heat up and drain the battery.
- kevin_thibedeau 2y agoWireless radios boost their gain settings when they have weak or no signal. The firmware devs should be mindful of conserving power in this scenario. Some don't bother.
- dotancohen 2y agoNo, I would actually expect that the phone would attempt higher power when connectivity is spotty. That is a feature, not a bug.
