Can I buy an extended battery?
I find that the battery runs out on standby in less than three days. The original claim on the web site was that it would last ten days on standby.
If I use the phone a few times to talk or text, it last less than two days. I have turned off Wi-Fi and blue tooth and I am not running any apps.

You can get an extended battery but it still won't last as long as you are looking for.
That is totally normal for a smartphone. Most smart phones require a daily recharge - unlike their basic counterparts. Even a higher capacity battery will not last for 10 days. Note that I speak as a user, not a rep.
I personally have not seen an extended OEM battery for this particular phone. I notice that there are several after-market (non-OEM) batteries that have a higher mAh rating but it doesn't seem to necessarily extend the battery storage ability from what I've read ...like this one (copy-and-pate):
In addition to turning off the Wi-Fi, be sure to also turn off the mobile internet connection provided by the carrier as you may be connected to the internet and not be aware that you are (I'm kind of thinking that this could be the case in your situation).
Also keep in mind that the published standby times given by the manufacturers are measured under ideal laboratory conditions and real-life experience comes nowhere close. Many factors play into the measurement too such as distance from the tower ...if you are a long way from the tower or your signal is weak, it will deplete the battery much faster.
If you don't mind incoming calls going to voicemail (you can always turn the phone on periodically to check for messages or check for messages remotely), you might think about powering the phone off or put it in airplane mode until you need to make a call or otherwise need to use it.
