Hello guys, I am looking for cheap 8″ tablet, and based on availability, I am currently picking from Chuwi hi8 pro (with preinstalled dual-boot, so the issues reported on this forum should be solved), or Teclast x80 plus.

Chuwi hi8 pro
Pros: Better build quality
Cons: FullHD screen – it is con, because theoretically, it should have FAR worse battery life and i personally think, that 1280×800 is enough for 8″

Teclast x80 plus
Pros: Slightly lower price and shipping time, theoretically longer battery life
Cons: Bad build, big gap between glass and actual display

Could somebody help me with picking one please?

The question I have about battery life with these sorts of tablets: At the moment, I have two and a half year old 8″ tablet with Mediatek chipset (MT8389, 28nm) with 4000mAh battery, and the battery life is actually about 4-5 hours but when it was new, in standardized test of streaming 720p video with 50% brightness, it done solid 7 hours.
Tablets like Teclast x80 plus are usually claimed to have battery life about 3-4 hours (also by Chris). I find that hard to believe, since atom z8300 is made using 14nm technology, which should have positive impact on battery life. Also, I found some german video on Youtube reviewing Teclast x80 plus, and from what i was able to understand, it managed to stream 720p video with 50% brightness for 8 hours, which i find close to what I will be expecting from me experience.

Can anyone with actual experience give me any input?
All replies will be greatly appreciated.
