Maximum Capacity is at 98% in less than 2 months on iPhone 16 Pro

I’m very disappointed with the iPhone 16 Pro’s battery performance. After 48 days of moderate use, the maximum charge capacity has dropped to 98%, and I can’t even say there’s any improvement in battery life compared to my old iPhone 14 Pro, which had 84% Maximum Capacity after nearly two years of use. If this trend continues, it will reach 80% capacity in less than 14 months and approximately 310 charge cycles. It’s shameful!

Here are some specific details:

• I charge it using the Apple 35W Dual USB-C Port Power Adapter, either with the original cable that came in the box or with the Apple MagSafe Charger.

• I don’t use Always On Display.

• As shown in the attached images, I use it for about 2 hours per day, under normal temperature and humidity conditions.

• I don’t use it for car navigation, social media, movies, games, or any other intensive apps.

• I use an Apple Clear Case with MagSafe.

So, what can I do to get this “amazing” phone to at least match the performance of my old iPhone 14 Pro?

Iphone 16 Pro Max, Battery health 100%, 28 cycles.

Always charging up to 90% and don’t let it drop less than 20%

Recalibration of your battery will only happen when the phone is allowed to charge to 100%. Even when using the 80% limit, the phone will automatically charge to 100% to perform this calibration and if you manually prevent that from happening, then the battery will not calibrate and remain at it's previous Maximum Capacity.

Once you allow the phone to charge to 100% through several cycle as it will automatically do when using the 80% limit, then you will see a larger than expected drop to reflect that actual state of your battery. The number you see for Maximum Capacity is just what was determined when it gets calibrated, it does not mean you instantly see a drop in performance when it shows 98% after it has been calibrated. It could remain at 100% forever without any calibration occurring and that does not mean you are going to have the same performance as if it was brand new. Eventually you will see a message that the Maximum Capacity cannot be determined because the battery has not been calibrated.
