Help Stop charging at 100%?

[Stingrayracing]

I don't know if this has been addressed before but here we go. I usually put my Turbo on charge when I go to bed and pull it off charge when I get up. I have noticed that if I grab a cup of coffee and check a few emails and then put the phone back on charge until it reaches 100% and unplug it takes considerably longer for the battery to discharge down to say 95%. If I don't recharge after the initial charging my battery will drop to 95% or below much faster with the same usage. Does this mean that once the battery reaches full charge over night it starts to discharge slightly while on the charger? I get much better battery life if I unplug as soon as it reaches 100%. Anyone else notice this?

I've noticed this too...charge lasts longer if you take phone off charger soon after reaches 100.

No

Yes, I think that this is exactly what happens. Li-ion batteries are dangerous when they near full charge - their temperature can spike, etc., so charging circuitry will shut down charging and occasionally trickle to keep it relatively full charged.

I think that 100% charge is an approximation and battery packs never get fully charged (just as 0% is a level that's higher than true full discharge and leaves the battery pack with enough capacity to run the charging circuitry.)

Yes. That make sense.
