How long will you keep a phone before buying a new one?

A long time..

for every five new phones my hub gets i get one .. just because they make the old ones obsolete (non functional due to updated systems elsewhere)

Forever

I keep it until it's impossible for the other end of my calls to hear what I'm saying.

As l Iong as it isn't broken and still works...think this phone is 8 yrs old now

i just got the i16. because the speaker has gone in my 12..

so that long..

Until I stops working. I don't like changing phones all the time

Till a full battery gives me about 2 hrs of screen time , so WAY too long

As soon as this Nextel flip phones walkie-talkie feature gets any worse, I'm moving on!

until someone makes me get a new one.

2-5 years

Until it's un-updatable

Until I get pissed off and throw it
