Which older Blackberry has the best battery life?

I need a 2nd phone as a backup phone. It will be used for calls, the odd text and maybe a very small bit of web browsing.

My question is: which of the older Blackberry phones and i'm talking ones I can buy for sub-�50 on eBay will be the best on battery life? If it lasts 2+ days i'd be very happy. I don't want something i'll be charging every single day as a backup phone.

Thanks in advance!

I have a Z30, which is really close to the Leap. They have huge battery life. I can go 2 days on standby, if you don't load too many apps. Good luck. Check the BlackBerry web site because some devices are on sale.

My 9930 can last about a week. It's my backup phone, used mostly for reading books now.

I'd say the bold 3 (the one before the 9900)

Z30STA100-2/10.3.2.2876

If you can live without the Web browsing just get a old flip phone.

Battery lasts a week and t9 is the bomb.
