Yes, but those phones are also not drawing the power from the battery at the rate that our helis are.
It's when you have a high draw (Normally tolerated just fine above the point at which you should land) AND the battery is allowed to drop too low voltage-wise. This is when they get HOT QUICK!
As I stated, I THINK the 3v limit is the "NEVER go below this point" voltage, for safe operation over a long time, I still think 3.6 or 3.4 is the actual cutoff point most experienced flyers are using.
I may be wrong, but safer is better, plus we're talking about the last few breaths the battery has in the charge, it's already not going to have the "Punch" that it has at the beginning of a flight, why chance hurting the battery for a couple extra seconds of flight? IMHO
If I AM Wrong, someone please tell me. I Know what it says from the manufacturer, but I'm MUCH more interested in what expert heli flyers using BIG expensive LiPo packs are doing!
You can BET they know, at Hundreds of dollars per pack!!!
