what config?

> With GSM on in suspend it should last for 140 hrs

only when deep sleep is usable.
the only time i ever heard of 140h suspend were the mail from daniel  
willmann after he applied a hw fix to #1024.
my fr suffers from #1024 and thus has to be set deep sleep never -- which  
means about 50hrs in suspend.
with deep sleep adaptive it works up all the time, which means a suspend  
time far less.
