First look: Galaxy Tab S7 and S7 Plus [in pictures]
At Samsung's online-only "Galaxy Unpacked" event this week, the company unveiled two new Android-based tablets, Tab S7 and S7 Plus.
Since its debut in February 2013, Microsoft's Surface Pro has developed into an exemplary tablet/laptop-replacement device, and also inspired a thriving 'clone' market. Here are some of its key evolutionary stages.
The original Surface Pro was widely criticised for its poor battery life, but Microsoft and its component suppliers have steadily improved performance in this critical area.
The battery life figures for the Surface Pro 3, 4, '5' and 6 are Microsoft's estimates for video playback time with wi-fi on and auto-brightness disabled (on a Core i5/8GB RAM/256GB SSD device); the figures for the Surface Pro and Surface Pro 2 are averages from multiple reviews.
Unless you run demanding workloads with screen brightness turned right up, the latest Surface Pro models should give you all-day (that is, over eight hours) battery life.
