Adding remaining time on battery widget

Summary

There is simply no way to get an accurate number for the remaining time (it's not possible without predicting the future ;-). As soon as you switch e.g. from working on document to watching a video or compiling some heavy piece of software to battery of your device will get used much faster and thus the "remaining time" of your battery decreases in a much faster rate than "predicted".

"Smart" batteries (e.g. those with support for SBS) are generally only found in laptops (so devices are out) and do a very good job of knowing the current percentage, but do not solve the future-use-prediction issue.

History

There were already several discussions about adding the remaining time. See e.g. [1]
