I absolutely understand your concern about battery life, but:

- A better screen would likely require more power, especially if the resolution was higher. OLED screens are also prone to burn-in, which can be a legitimate concern, especially with games that have a persistent hud.

- I think it's quite impressive we've managed to get the current battery life, considering how relatively small the battery is.

Overall, it's a great first generation product, which would likely not have been possible just a few years ago.
