Which is worse for my battery lifespan? Overcharging (e.g charging from 9pm to 5am) or charging cycles (more than once a day)? My phone is a Galaxy Note GT-N7000 Intl model with a Li-Ion battery. My battery life isn't bad at all, i just want to know which one degrades battery's lifespan the most before getting a brand new battery replacement.

Thanks before!
 
From what I've read (this may be disputed here) there is no difference.
A li-ion battery has a certain life of X amount of full charge cycles and two 50% charges (for example) equals one 100% cycle so it doesn't really matter and it's impossible to overcharge your battery on a smartphone. It will stop charging at 100% and then start charging again once the battery drops to a certain level so over the course of a battery's life it will all balance out on a phone that's always on

So smartphones nowadays really have overcharging protection, huh? A local technician said that mine doesn't have one which is the cause for my battery's death, which i strongly suppose was just because of aging (3 years old).
 
If you've used the battery for 3 years, and have used most of a charge cycle per day, then it's been through about 1000 cycles. That would certainly be enough to degrade a typical phone battery significantly.

Personally I've never owned a phone that doesn't have overcharging protection, even going back to 1994! Now if you do stupid things like unplugging a fully charged phone then plugging it in again to try to deliberately overcharge it that's a different matter, and you could damage the battery if you do that on a regular basis. But if you just plug it in, leave it overnight and then take it off charge in the morning there's nothing to worry about.

What you should try not to do is run the battery flat on a regular basis. That will degrade a lithium battery faster than if you top it up before it gets to that point.
