I'm not so sure it's just because it's iDEN, I believe a lot of the poor battery life is due to MOTOROLA.

Moto's have in my experience always been battery hogs relative to any equivalent device from any of the Korean or Japanese manufacturers. FOr example, our Verizon Moto phone used the battery just as much as any of our iDEN phones, and furthermore, the Verizon Moto had to have it's battery replaced every 18 months or so. And that was Moto on CDMA!

Actually, the best battery efficiency I have personally experienced with any mobile device was my T-Mo Blackberry, and the spouse's Verizon Blackberry is just as good. So from my experience it all points to MOTOROLA being poor at circuit design for battery life, not iDEN per se.

That said, the best way to care for a lithium-ion battery device is to charge it daily, don't be using the device when you're charging it, and take it off the charger very shortly after it finishes charging. The big killer of Li-ion batteries is heat. Simultaneously charging & using the device causes a huge temperature rise in the battery. Also, deep-discharging them and recharging them from a deep-discharge causes a significant increase in battery temperature for a longer period (not as detrimental as simultaneously using & charging, but still significant). Li-ion batteries do not develop the "memory" problem that NiCad batteries do, so there is absolutely no downside to charging your Li-ion powered phone more frequently for shorter periods.

I've been on iDEN phones for 8+ years, charging them every morning and not leaving them on the charger any longer than it takes to fully charge them, and (a) batterylife is a non-issue for me because I start each day fully charged, and (b) I've had most of my iDEN phone's Li-ion batteries last at least five years, one of them lasted just over six years.

So at least consider charging your devices daily so you don't have to stress out about a talk time of only 4 hours. It might also increase the battery's useful life before requiring replacement.
