Re: Charge speed vs battery life

Does anyone know what the most ideal charge speed would be?

There is no simple answer to this.  The question just raises
many more questions. 

Battery type and chemistry?

How long do you expect the battery to last? 

Is it easily replaced?
 

The 'conventional wisdom' was that fast charging leads to
shorter battery life.  Most phones now have a fast charging option. 
My Oppo phone fast charges at 33W (11V,3A), which is enough to charge
it in about one hour. Oppo claims the battery can take up to 1500
charge/discharge cycles before battery capacity falls to 80%. 
As I only charge my phone once or twice a week, it will probably
be in the recycling bin long before the battery wears out. 

I only use the fast charger when necessary. For most charges,
I connect the phone to an ordinary 10W (5V,2A) charger.
Does this extend the battery life? I don't really know.
The phone gets warm, but not excessively hot on the fast
charger. It is noticeably cooler on a slow charge.

After 18 months of use, there is no measurable reduction
in battery capacity. I usually get 3-4 years out of a phone
before it gets broken or becomes redundant.  I haven't lost
one because of battery failure yet....
