Seido’s 3800 mAH Extended Battery: Never Stop Surfing Robert Evans October 18 Gear, Modern Vagabond, Review This post may contain affiliate links. Read our disclosure.In the land of long flights with no power outlets, the vagabond with the biggest battery is king. I rarely use my smartphone for more than occasional browsing and navigation. But on long flights it’s much more convenient for watching movies than a giant, clunky laptop. The only issue arrises on long flights – after nine hours of media playing most smartphones are close to dead. And no one wants to be phoneless when they land. Enter Seido, kings of the extended battery. I had the opportunity to test their 3800 mAH Innocell battery for my Samsung Galaxy S3. And I walked away extremely impressed. In Detail First, the downsides. This extended battery will make your lithe little smartphone into kiiiiind of a fatty. It adds a bulge to the back, and renders any cases you currently have rather useless. Because of this, I wouldn’t recommend this battery as a daily carry item. You’ll be better served by saving it for situations where you know you’ll need the added juice. Now the positive bits. With this battery, I regularly see 2+ days of normal use without needing a recharge. That includes navigating my way home three or four times, a couple of hour-long runs with Pandora streaming and a solid hour or two of browsing per day. In airplane mode, you can expect to get through a nine hour flight with more than half of your battery left upon landing. I’ve used this battery on two eight hour road trips while my phone acted as a WiFi hotspot. In both cases, I arrived at my destination with enough charge remaining to make it through a night on the town. Pricing You can buy Seido’s badass new battery for $69.95 right now.
