Hello people I recently acquired my 11t pro and I know that the 120w charging, first it's amazing, but second it's kind of concerning to think that such a charging speed might not wear down the battery life even though Xiaomi claims 800 cycles and a bunch of certifications.

So I've decided to only use 120w on hasty situations or while traveling, etc. And I happen to have different xiaomi chargers.

The question is which do you think is the best wattage or charger to make battery life span longer 22.5w or 33w?

(wish I had the 67w from the 11t, but unfortunately I don't)

You're correct. Fast charging is poison for battery lifespan, of course the device makers love that because $. As low and slow as possible is the way to go, 18-25 W as a good trade off I would say. Some, including myself go even lower.

yeah,I haven't tested the 11t pro but with a redmi note 9 using a samsung note 9 charger it looked like the redmi wasn't getting any charge up. So that low is good?

Well just as an addition I've tested several chargers with different wattages and these are the results in terms of time:

Samsung 10w - 2h:40min ±
Xiaomi 18w - 1h 30min ±
Xiaomi 22.5w - 1h 05min ±
Xiaomi 33w - 50 min ±
Xiaomi 120w 17 min at least for me.

Charging from around 10 to 100%

I use a 33W charger from my K30 Pro Zoom. I charge from 20% remaining to 90% in 30 mins. Probably 45 mins if totally drained but never have to wait for an hour to fully charge. I only use 120W during business trips or Out of town.

By the way, your cord needs to match the type of Charger you are using or you'll just end up with a bottle neck charging.

I think the best option would be 65W, either mi charger or anker. Im currently using anker 65w charger, and oh my god, im getting a beautiful battery life of upto 8 hours sot on heavy usage. And by heavy usage i mean, streaming, maps.

With heavy games as well, its a bit lower. But charging with 120W affects the battery negatively. And i think it doesnt charge it completely even though it shows 100%.
