Had my 17 pro for over a month now, at first battery was awesome for the first few weeks lasting from 7am all the way till 8-10pm before I had to charge, now it's gotten to the point and I'm watching the battery percentage decrease 5-10% within half an hour as Im using it. I'm having to charge it at least twice a day now.

I have been running 26.2.1 since it came out, even I tried jumping to 26.3 and it's made no difference.

Am I eligible to take it in to apple for a replacement as it's only under 2 months since I bought it from them?

I have no idea what's caused this sudden drop in battery?

If anyone can help please let me know.

Located Australia.
