Hello :)
First time ever l got new apple iPhone 16; so can You give me some advice should l first charge the phone till 100% .....or should l unpacked lt and start no matter the battery level?
 
3 charge cycles?
Yes...so once upon a time, there was a rule that You must totally empty out the battery and after that charge the battery till 100 percent and repeat that 3 times due to calibration :)
 
I know Apple used to recommend battery calibration but it isn't necessary anymore. Battery calibration is done through software now.

3 charge cycles? I don't think that was ever a thing.. it sounds like someone was taking a "rule" about NiCAD batteries and applying it to LiIon batteries - LiIon batteries don't have a "memory" like the old NiCAD batteries had.

I have been using IPhones since the iPhone 4S was release and I have never immediately charged a phone after unboxing. Do keep in mind that LiIon (Lithium Ion) batteries don't like being completely discharged, so I never allow my Apple devices to go below 10% battery and I charge them to about 90%. I have owned the 4S, 5, 5S, 6S, 7, XR, 11, 13 and 15.. and I've never had any problems with any of them.
 
I know Apple used to recommend battery calibration but since iOS 14.5 it isn't necessary anymore. Battery calibration is done through software now..
Quite inaccurate!
It applies for 14.5 or later specific to 11 series. Not universal.

It was the mentioned right below the title.

Show me any support document that Apple has released that supports the fact that you need to calibrate your battery.
I'm not saying Apple requires users to calibrate their battery. I'm just pointing out to the fact that your statement is false.

iPhones 15 and up occasionally charge to 100% to calibrate their battery but is not the case with older models. This implies charging to 100% is required every now and then for the iOS to gauge the actual battery capacity aka calibration. This is the case with any Li ion batteries and even more so as they age.
Battery calibration only tells the iOS that 50% charge is actually 50% charge and doesn't affect the functionality.

I'm only asking not to spread misinformation. There's always something new to learn.

So my post was correct. Thanks for proving my point!

You don’t need to prove anything to me. Just stop spreading misinformation.
Good luck!
Maybe you should quit trying to be the forum fact checker. Your post was directed at the information I gave to the OP not to you. If you wanted to post something useful to the OP that's fine but you chose to critique information that was correct except for the link. I removed the link and now the post is factually correct..

Ppl come here to get factual info on how to troubleshoot their issues. You spreading misinformation does the opposite.

You amending the post only proves your admission to inaccurate post and that someone pointing out the inaccuracies are needed.
Responding with a laughing emoji isn’t a counter argument.

Appreciate you correcting the initial response.
 
@_dragan There’s no need drain the battery to empty for Li ion batteries which is the case for most modern devices. Just use your iPhone as is.

Only look into calibrating the battery when you notice sudden drops of 5% or more at a time in the battery graph. Until then enjoy your new iPhone and charge it as often as you like.

Yeah, the battery graph is only a "best guess" anyway and is based on electrical pressure. It's accurate enough for us but it isn't exact.

And sudden drops mean the battery management system has trouble approximating the available current. This causes the device to last much longer at 1% before it shuts off. That's the only case I'd recommend calibrating the battery and doesn't happen till the battery ages a bit.

I'm looking to buy my very first iPhone in the next 3 months. I've used Apple in my house and only Apple (iMac, iPad, MacBook, AppleTV HomePods, iTouch, etc). All the deals I look at call for me to trade-in my old phone. I've only had landlines or the work phone issued by my employer and I can't trade that in, I have to give it back when I retire. So, where or who can give me a deal on the iPhone 16S?????
