Fully Charge my iPhone before use?

What do you mean not apple products? Yes my example was on a HP, but the same concept is in regards to all Lithium batteries.

The iPhone trickle charges, but someone can correct me if I'm mistaken.

Anyone saying you need to do need to let it die and then charge it to 100% because it "feels good" is spreading bunk.

For the health of the battery, you don't need to do this. The Lithium-Ion technology has made this a thing of the past.

However... there still is a purpose to doing it; albeit, it's not for the health of the battery. Most people call it calibration - it allows your electronic device to more accurately read the battery's actual capacity.

Every Apple product I've gotten with a battery in it came fully charged out of the box. The first iPhone I got, I was using it in the car on my way back from the store. I expect I'll get a full day's use out of my new 4S when it's delivered on Friday as well.

Apple does use some interesting battery technology, all with the idea of helping you get the best real world use out of it. So, just use it like you'd normally want to use your device, and the battery will be just fine. My old 3G battery is still going strong, and I've never done any fancy charging/draining schemes.

The last two times I let my Apple products run to 0 battery (a MBP and an iPhone 3GS), I had crazy issues. My iPhone entered Recovery mode, which resulted in me losing a couple weeks of pics/texts/notes, and my laptop had some sort of data issue that caused the time clock to go back to 2001, among an issue with some authorized software I had that uses a virtual-dongle. I don't let my Apple products die anymore.

What your supposed to do for max battery performance is don't charge your phone, instead use it until it completely dies from low battery. Then charge it overnight.

I read an old post here on forum but I do not remember where..anyway I made an screenshot at that time, here it is:

I am also not an electrical/materials engineer, but I am a mechanical engineer.

I listened in on a seminar regarding Lithium Ion batteries and how best to keep the earth 'green'. Per seminars with Professors who studied in these fields this was their response, which has proven true on the majority of my devices:

Do not keep a phone or laptop plugged in after it reaches 100% and do not let the battery drop below 20%. There is no need to cycle the power fully up and fully down, this was used on old technology to calibrate the sensors in the phone as well as the battery. If the charge is brought down to 0, the issue is the cells begin to slowly disperse/separate from one another causing degraded battery life.

Hope that helps - I found this to be true as my laptop batteries died so quickly from keeping them plugged in all the time.

Good God. No to all of these. Go read the links from Apples site.
