Original Title: my battery health 14pro decreased by 2% can it be my 33 watts charger ?
iPhone 14 Pro, iOS 18
No. A higher wattage power adapter will not degrade nor damage the battery, it will only take what it needs, which is 20W and no more to Fast Charge. You will see that your battery health can drop a few more or less points occasionally which is absolutely normal, and this is likely a pure coincidence.

Not likely. You can expect the battery health to drop 1% a month on average. The drop is not linear, so some months may not drop at all and other months will drop more. That is normal.

No
Don't try to babysit the battery. It is going to do what it is going to do. All that you really need to do is replace the battery when it is down to 80%.
By the way, you may not be aware that Apple always rounds down any tenths of a percent on the battery readings, so a battery that is actually 89.9% will display as 89%. That same battery might have dropped from 90.1% to 89.9%......a drop of only .2%......but it will look like the battery dropped a full 1% from 90% to 89%.
"Health" decreases in all rechargeable batteries. Your battery is a chemical reaction in a small box. With use—any use— or even age, the chemicals that allow you to store power degrade and health goes down. "Health" is the current capacity divided by the original "design" capacity.
Think of it as buying a new metal water bottle:
— New, it is rated to hold 16 ounces.
— You fill it to the top and it holds 16 ounces; that is 100% of capacity
— Over several years of hard use and drops on mountain trails, the metal body has collected some major dents.
— Because of the dents, when you fill it to the top, it now holds only 15 ounces of water.
— 15 ounces is 94% of the original 16-ounce capacity
In battery terminology your water bottle's "heath" is 94%. as a result of normal use and a few bumps.
A battery will lose capacity even if not used. It's all about the chemistry.
So, beyond that, to get effective help here where we can neither see nor touch your phone, you need to share a bit more information:
Even if use a 140Watt charger iPhone will take only what is needed.
Can a 33W charger affect iPhone 14 Pro's battery health?
