Halakhah for Berakhot 18:13
אמר רב הונא הלכה כאחרים אמר אביי לתפילין כאחרים לק"ש כותיקין דאמר ר' יוחנן ותיקין היו גומרין אותה עם הנץ החמה
Rab Huna said : The Halakah is in accord with the "others." Abbai said: [The Halakah is] in accord with the "others" with respect to the Tefillah; but with respect to the Shema' it is in accord with the Wetikin. For R. Johanan said: The Wetikin used to conclude it with the sunrise.
Maaseh Rav
The time for putting on tefillin is like 'Others" in Berachot 9. One should wear them all day, and even to do business in them is permitted, and snacking is also permitted. But idle activities are prohibited. If one is worried this seems haughty before other people, one may wear only the hand tefillin. In any case, it is better to wear a small head tefillin and keep the straps covered than to walk with only the hand tefillin.
