so i was reading about, from apple itself saying u should drain your battery till it shut down, then recharge it fully. it suppose to recalibrate the battery. i notice the boss pref numeric battery, and also the numeric battery on lock screen. there's a different. on it, so i gave it a try

before i start the process, the lock screen battery was at 67 percent, and boss pref was at 53 percent.

then i did the process and my lock screen batt at 50 percent and boss pref was at 48 percent

so i was about 2percent off after

yay!!, work, but guess what, my battery life was great for the first two charge. it last forever long,

well too good to be true. after all that my battery life worst than ever.
the way i use my phone use to last 14hr without charge.
now last 7-8 hr without charge. hmmm i think apple is lieing lol.

anyone ever did the drain process. any story to share with us???

Cant say I've ever really tried it....well, not on purpose aside from it dying cause I couldnt get to a charger.

But its good to do this with any Li-ion battery.

u know, i was wonder about the battery. i notice, i use to be on sprint and running htc touch, i went thu 4 battery, and i find out once it full charge u want to unplug the phone. if u keep it charging it will kill the battery life, but sure it did, the 5th battery once it full charge i unplug it, the battery will last at lease 24 hours.

does iphone stop the charging process once full charge? or it's contiune charging it no matter what

From what I can tell on the icon, it appears as if it starts using the power cable to stay on.

Ive re calibrated the battery a few times. Seems to help battery life. I'll do it if I sense its not holding a charge as well despite shutting down unneeded processes. Usually respring or reboot will do this for you.

Also even after you show 100% charge you will need to leave it plugged in longer as it will show 100% but really be say at 85% after a full discharge. If I need to use the phone in that time frame I leave it plugged in.

How do you know that it's only at 85% when it shows 100%? Although I have noticed the need to charge it longer than when it initially says 100%. I was just wondering if you read it somewhere or it's more from personal experience.

You don't. I picked 85% as an arbitrary number ti illustrate the point that the battery continues to fully charge after indicating a "full" charge. Assuming that iPod and iPhone batteries charge in a similar fashion:

From apple support website:

Once connected, your iPod battery will be 80 percent charged (often referred to as quick charge) in about an hour, and fully charged in about 4 hours (time may vary with models - iPod nano is 80 percent charged in 1.5 hours and fully charged in about 3 hours and Fifth Generation iPod is 80 percent charged in 2 hours and fully charged in about 4 hours). You can disconnect and use your iPod before the battery is fully charged, and you don't have to wait until it's completely empty before charging it again. This is because lithium-ion batteries, such as those used in iPod, have none of the memory effects seen in nickel-based rechargeable batteries.

It is my belief that the iPhone will show fully charged when it reaches that quick charge level.
