Dell Mini 3i battery review

In the past month Dell launched its first smartphone Dell Mini 3i in China. We had opportunity to look at Dell Mini 3i and test its battery.
The Dell Mini 3i is equiped with a rechargeable li-ion battery rated at 920mAh. Its original battery code are H11S22 and K158R. It states cells made in Japan and assembled in China.


As far as we know 920mAh is absolutely not enough for a big touch screen smartphone. Mostly because the battery house is too thin and can’t hold a battery with higher capacity. We thought we should have to charge this battery each day to get enough juice. To our surprise, this battery can last two days under the condition of one hour call, sending 20 messages and browsing internet half hours each day. It performs great work. We think this possibly results from Dell Mini 3i’s optimization of internal circuit and system.
Anyway we hope Dell can release an extended battery with a battery door. Because 2 days is a little short for a smartphone.
