iPhone 14 Pro Max battery drop from 97% to 94% in 12 days

I can guarantee that your battery will continue to decline. So can anyone else who might read your post.

All batteries decline. They are chemical devices. The chemicals will change with age.

Replace the battery when the Maximum Capacity is down to 80%.

Battery health is at-best an estimate based on the trending of several other measurements; all of which can and do fluctuate and are themselves subject to measurement errors.

Don’t obsess over short-term fluctuations; DO pay attention to long-term trends. (e.g. over months)

Regardless, a >90% reading indicates a quite healthy battery.

Due to the way in which Apple rounds down any tenths of a percent in the battery settings, it is possible that your battery really declined from 97.0% to 94.9%, a loss of 2.1% when it looks like the battery declined 3%.

Unfortunately, Apple only displays whole numbers without any tenths of a percent.

Chances are, you updated your phone to iOS 26 in the last week or so, and if that is true, a 2% decline would be expected since everything has to be re-indexed on the phone, which requires the battery to work overtime and then some for a few days.

How old is the phone? Do you remember the approximate date that it was purchased?

On average, and as a general rule-of-thumb, the battery will decline about 1% a month. The battery decline is not linear. Some months, it might not decline at all, then drop 2% the next month.

If you can get 2 years of use from the battery in your iPhone 14 Pro Max, that is not bad.

Not sure there is really any significance to a 3% drop in the measurement in that span. You are still well above 90%. Apple has already provided a solution: replace the battery when it gets close to 80%

my apple care+ has expired and to replace the battery it costs 9800 rs

You are a long way from needing to have your battery replaced. But one day, if you own the phone long enough, you will need to replace the battery, so maybe start saving your money for the future expense now.

94% after more than two years is very good, nothing to complain about. My phone is 87% after less than 2 years.

You should expect to replace the battery about every 2 years. If you are not able to do that, you should not ever buy another phone.

You did not tell us how old your phone actually is, but I have feeling that your battery is doing better than average. You should be thankful.

If your battery was average, it would now be less than 80%.

If your battery is now 94%, you should send flowers to Apple for your very very good luck.

My phone is less than 2 years old and the battery is at 84%. It will probably be about 80% when it is 2 years old.
