Is my phone battery dieing or is it the service?

Question

I have a Motorola Razr that I bought from my mom so I think it's about two years old or so. The battery is only going one day before it dies and that is with an average of 2-3 calls per day (usually only 5-10min) and 5-10 text messages a day. Not very high usage in my opinion. I have heard that if you don't have good service the battery dies quicker, and in my house I only have 0-1 bar most of the day. This just started happening the last two weeks thought, it used to go 3-4 days and when I'm at my moms (full bars) it lasts even longer than that. Is the battery dieing or is it the service? I'd call Verizon, but they tell you that batteries are only supposed to last like six months or something ridiculous like that (they told me that w/ my husband's phone.)

Answer 1

Li-Ion batteries do have a limited lifespan although they should be good for at least a few years (though that of course depends on your definition of good).

The worse the signal you're receiving though the more power the phone has to use to be able to transmit to the base station (transmit power is constantly adjusted by the base station telling the phone to increase or decrease power).

I think it's a combination of old battery and bad signal, the capacity loss of old Li-Ion batteries is most apparent when under heavier loads.
