iPhone 16 pro battery sudden drop 2%

Hi bro,

I just have a concern regarding my battery health of iPhone 16 pro, I Bought it last year October now it’s at 304 cycles and 92% battery health

At 293 cycles it was at 94%, then at 299 it was at 93%, then at 304 it came to 92% , I don’t know the reason for such drastic drop suddenly.

I’m doubtful if there is any issue with battery, or if the battery is defective?

I’m also attaching the screenshot of this drastic battery healthy drop for your reference.

Please check and I’m hoping for a positive response from your side, also please let me know if any service should be done my warranty is eligible till 4th of next month.

thank you for your time!

Hi bro, as mentioned in our battery health tips related videos, we have to calculate from the month of first use. so in your case its 10 months usage and 8% battery health reduced. which is totally normal. dont worry. continue following the charging practice as suggested. that will help to gradually see the reduce of battery health in upcoming months.

If there is any issue in the battery, we will see it dropping to 80% within 1 year period.

No such thing happened and yours looks perfectly normal to reach that 2.5 years time to reach 80% level.

Hi bro, thank you for your reply, my concern is why there was a sudden 2% drop in 1 week time do I have to take concern about it is it an issue?

Thanks for your time!

its the refresh that happened after some delay bro. happens sometimes. not a problem. some months we dont see the reduce, and refresh in future too.

Okay bro thank you for your time!

No disturbance at all bro. as said, its refreshing and you are seeing the drop now after battery health updates at software level. calculate from month of first use where its 11 months 9% reduce. totally normal bro.
