I usually charged my iPhone 11 with a 5W charger even during the day to preserve the battery from the heat of using the 20W charger. It charged at a normal speed where I’d see the percentage increasing every few minutes.

But with this iPhone 14 Pro using the 5W charger it’s so slow. I’m not seeing the percentage even increase by 1% for a long time.

Is that expected with these new phones? Bigger batteries? I thought they wanted us using the 20W chargers for fast charging but maybe 20W is the baseline now?
 
I use the 5w charger for my iPhone 14 pro max, it still works fine. Yours could be wore out. Yes it takes a little longer but I don’t use it all the time, just when I want a trickle charge, that is usually best for the battery anyway. I also use MagSafe. I charge my iPhone when it reaches 40% and stop charging around 85% for optimum battery health. I rarely charge to 100% because it puts a strain on the battery. Lots of articles on that style of charging.

I use my 5w charger to charge my Pro max overnight while I’m sleeping since I still have the charger and charging speed doesn’t matter for me overnight. In my car I have a quick charger in the event I want to bump my battery up during the day. Though with the Pro max it’s very rare I need to do that.
 
Rene Ritchie says to not worry about it.
Why work and lose time and energy to micro manage your battery? Just let the battery work for you. Change it when it’s time.

Agree with you. My previous iPhone 12 pro was put on the charger each and every night and removed the next day at 100%. I’ve never worried about all these crazy Micromanaging of your batteries Stuff. 🤪

When I used a 5w charger for my 11 Pro Max, the 5w charger got REALLY hot. I have a desk job so I don't mind the long charge times but ... after awhile, I noticed the plastic discoloration from the heat generated by the 5w brick - also I was getting a burning plastic smell ... so I moved up to a 12w iPad USB A charger.

And well, now, I just charge with whatever. After doing this with several phones, I do not see any noticeable savings by using a slower wattage charger.

My 13 Pro Max is now starting year 2. I've been charging it with a 35w Anker, via usb C port on my MBP, and sometimes via my 60w MacBook Pro charger (USB C to Lightning). Still has the same capacity the day I bought it.


To more directly answer your question. Apple's % reader is often several % points behind actual charge level. So that first % gain can take a LONG time because of that reason. For example, say your phone is at 75%. Actual charge may be 73%. So putting your phone on the charger, it could take 15 mins+ to see a % point gain with a 5w charger as the phone climbs to 76%+.

To those who don't use their phones, leaving their phone on a slow charger may work for them. Ever since I got rid of my iPad, I use my phone now more than ever. Thus, super fast charging saves me time.

Do not use a 5w charger unless you plan on charging overnight. Even my 12 Mini took over 3 hours to charge at 5w… I now have a wired fast charger along with 15w(?) MagSafe puck which is far more bearable.
