These are also the same batteries that every company in Japan that offers pocket WiFi rentals are using. This means that regardless of the company you rent from, the battery life will generally be the same. Okay now that you know a little about these Pocket WiFi batteries, let's get into the actual test. The test was simple. It consisted of taking the fully charged WiFi unit with me at the beginning of the day and timing how long it took for the battery to die or reach critical levels. It's got a battery of 3,mAh Charging the device fully at night took me around 4 hours.
I used it to surf the internet on my smartphone, and even streamed Spotify with it at night. The device lasted me from when it was fully charged at 9 am, until dying completely at around 7 PM when I switched to the power bank which eConnect Japan offers free with every pocket WiFi rental. This length was quite impressive considering some pretty heavy usage as well as being connected to 4G network for most of the day.
Lasted for 10 hours , the majority of time on 4G, until the battery died completely. I used the Pocket WiFi unit a decent amount, but there were long gaps throughout the day where I didn't use it either. This may have helped the battery last so long.
This image shows the Pocket WiFi screen after 7 hours of use. You can see that the battery bar in the upper right-hand corner is down substantially, but it still reads green. This means that the device still has some juice left in it. Verizon claims that the 4,mAh battery in the MiFi L will last up to 20 hours. While my review unit didn't meet that lofty ideal, it came close. When connected to a single laptop running the Laptop Mag Battery Test Web surfing via Wi-Fi , the hotspot lasted 16 hours and 49 minutes.
That's about 2 hours longer than the MiFi L, which hung on for 14 hours and 43 minutes. Verizon offers 15 data plans for the MiFi L. The MiFi L lasts an extremely long time on a charge, can provide power to other gadgets and delivers excellent throughput for up to 15 users. What more do you want from a hotspot?
