Beneath the non-removable back is a 4,450mAh capacity battery. Samsung doesn’t make any specifics about how long you can expect it to last. In general use we could comfortably get through a day without charging.
Running a video on loop with default brightness, the 8.0 matches the Note 8.0 managing on average eight hours. That’s better than the Nexus 7 2, but a couple of hours off the MeMo Pad HD 7.
It has decent staying power lasting two days in standby mode and is a quick charger jumping up on average 15% from a critical battery level (below 5%) in 30 minutes.
The Samsung Galaxy Tab 3 8.0 is an example yet again of another Samsung tablet that does nothing compelling to justify the price. The specs feel old compared to its closest competitors. It would have been a decent tablet a year or so ago, but now it looks overpriced and underpowered.
You need only look at the alternatives to see why. The Nexus 7 2 at £199 has a better screen, more powerful innards and the premium look and feel, while the even cheaper Asus MeMO Pad HD7 is just £129 and matches the 8.0 for screen quality and boasts an impressive battery life making it better value for money.
The original Nexus 7 would even be worth a shout if you can live without the expandable storage options, and there are plenty more good alternatives in our best Android tablets round-up.
The Samsung Galaxy Tab 3 8.0 tablet is a solid performer and has a decent screen, but it’s overpriced for what you get. There are cheaper more impressive alternatives to spend your money on instead. It feels like Samsung isn't even trying here.
