Best charging practice?

[gidds]

What's the best way to preserve the Gemini's battery lifetime?

I charge mine overnight; I have a charging cable on my bedside table, and plug it in when I go to bed.  Is it best to use the power adapter supplied with the Gemini, or a standard USB adapter?  The supplied adapter is a fast charger; will that stress the battery more?  (A standard USB adapter charges much more slowly — though fast enough for my usage, as it's always fully charged when I wake.)

The best way of charging would be not too fast, and stop at around 80% capacity.  When the battery rapid charges, it gets quite hot which isn't healthy, so I use a generic USB charger (1A) which will completely charge over night.  If it needs charging during the day I will give it a boost with the fast charger up to about 60%, then swap to a normal charger for the last part.

There is an app called Battery Charge Limit, however it doesn't appear able to stop charging on the Gemini.

I had a look at the kernel sources and I believe it's not possible to make Battery Charge Limit work without modifications to the kernel. Unfortunately, modifying the charging code can be quite dangerous.
