I have used two different new batteries (used on the 7280 before) so I can say that it is not a battery problem. I keep Bluetooth off since I don't use it. I know T-Mobile does not have as good a coverage as ATT/Cingular and there may be greater "search" time. Any suggestions? Do I need to preset something to be more efficient? like a different Message Service etc.? Thanks.
For the last week, the 7290 T-Mobile unit is giving me great battery life like I reported with the 7280 before, recharging every 3 days. What has changed? Nothing on my side. It must be how the provider (T-Mobile in this case) interfaces with the handheld units. I have not changed the operating system and traffic email/sms/voice has been the same as always. I wish someone couuld explain what's up. Thanks.
