“Please give any insights on a regular HD versus the Ultra HD displays. Battery life, normal web surfing, occasional movies. No gaming, minimal photo editing. The thought of Ultra HD is nice but I'm concerned about battery life and additional heat.”

The battery life of the FHD 1920 x 1080 (FHD) version is up to 15.5 hours, and the UHD 3840 x 2160 (UHD) version is up to 10.5 hours. The battery life depends on the work that the device is performing. Obviously UHD resolution would have double the clarity of the FHD model. If you watch movies, view pictures or play games the higher resolution may be better for you. As far as the performance of both models, both have Core I-7 processors. The UHD model has a larger hard drive 512GB vs 256GB solid state hard drive. Both system have an internal fan to maintain normal operating temperatures.
Sorry, there was a problem. Please try again later.I have the 4k 1 tb model 920. I also used to own the yoga 910 4k model. I think the battery life on the 920 is better (even though the battery is a little smaller). Most of the complaints on the battery life are people looking at the battery meter and seeing the estimated battery life saying something way lower than advertised. But the problem is the meter fluctuates a lot because its trying to estimate from current usage. Sometimes it will say 4 hours and 5 minutes later it will say 9 hours (you cannot rely on the estimated usage time). Watching movies and web serving will give you a long time (you can binge watch tv on battery). I use my laptop in for college. I have never had to take the charger with me anywhere. I think you will be fine with either one unless you are literally on it all day long. I was concerned with what some people said about the battery, however, I have no complaints. Plus it charges pretty fast. Heat- Any device this thin with the performance it has will generate heat. But it is normal and supposed to. Mine gets warm with normal usage (video, web surfing). The 910 i used to have would get really hot... The 920 fans seem way more efficient and less noisy. I hope this answered you question.
