Reply To: LapBook 14.1 battery capacity?

Yes, it is really 7.4V. It says so on the battery itself and both Battmon as well as the tool Chris used, report it as 7.4V.

If it would be 3.7V and 9.000 mAh as Chuwi claims, it would be 33.3 Wh, where the tools report 45 Wh.

What I think is that somehow Chuwi calculates the capacity back from 5V, i.e. 45 Wh divided by 5V gives 9.000 mAh. Which it clearly is not. Around 6000 mAh would be more accurate.

Chinese firms are very “inaccurate” in specifying real battery capacity. As in: they lie.

I get 8 hours battery life doing mostly office tasks on the LapBook. Good enough for my purpose.

Processor max 2W (average, max is 6W), display around 2W, rest of the electronics about 1W, SSD around average 1W, gives 6W (10W when CPU on max). With a 45 Wh battery, around 4.5 hours (when gaming) to around 8 hours (office) should be normal.
