4 months old - stays "off" and holstered in my briefcase and use it only for an hour or so every few weeks. I give it a full charge (until all battery bars fill up), use it for an hour (about 15 minutes of data exchange), turn off for a few days, use it again for an hour, put it away, go to use it about 10 days later and it's dead. Won't even turn on. Need to hook-up the AC charger. Same pattern every time. (I had it set to "off" when holstered.) Any idea folks? Am I doing something wrong given spec 16 days standby? Did leaving it in the car during 100 degree days ruin the battery? Is this a warranty issue? Thanks for advice.
There's a few things that can be said about this issue. If left off and tuned on for an hour or a few days a week the battery life sounds about right. As far a leaving your phone in the car while it was 100 degrees outside depends on how long it was left in the car. I work in the warrenty dept for high end device/data device phones and i always advise customers if a phone is exposed to extreme temperatures for a period of time it would void the warrenty. How long was the phone left in the car? If it was for an entire afternoon while at that temp i would advise against doing a warrenty exchange.
