The BGR report mentioned this as well;
Motorola DROID RAZR MAXX review: A smart smartphone you shouldn't buy
Here is the applicable paragraph;
"I should mention, however, that the DROID RAZR MAXX doesn?t handle Wi-Fi connectivity well at all where power management is concerned. Some phones do better than others with Wi-Fi ? the iPhone, for example, lasts nearly twice as long for me on a single charge when constantly connected to a Wi-Fi network compared to when Wi-Fi is not in range. With the RAZR MAXX, it?s just the opposite.
I found that the battery drains much faster when the device is connected to Wi-Fi. Using the handset?s battery monitoring feature, I could see that Wi-Fi was always the No.1 drain on the RAZR?s battery when I left it enabled. When I disabled Wi-Fi and relied on Verizon?s 4G LTE network for connectivity, the display became the No.1 drain on the phone?s battery, as it should be."
So I am not alone in noting this and it's kind of messed up.
