iPhone 14 purchased from India have battery health down 1% in a month while my brother who bought from Europe….have its battery health in good condition

It's understandable to be concerned about differences in battery health and camera quality between iPhones purchased in different regions. Here are some insights and steps you might consider:

1. Battery Health:

   - Battery health can vary based on many factors such as usage patterns, charging habits, environmental conditions, and even software updates. A 1% drop in battery health over a month, especially after a software update, might not necessarily indicate a significant issue. However, if you notice significant and rapid declines, you can try calibrating the battery or contacting Apple Support for guidance.

2. Regional Discrepancies:

   - Quality differences in iPhones based on region of purchase are generally not intentional by Apple. Issues like battery health or camera quality variations could be influenced by factors beyond intentional manufacturing differences, such as usage conditions, software configurations, or network differences rather than geographical origin.

3. Camera Quality:

   - Regarding the difference in camera quality between iPhones, software settings, user preferences, or even potential hardware discrepancies due to individual units can impact camera performance. It's advisable to compare settings and perform tests in controlled conditions to accurately assess the differences.

4. Troubleshooting Battery Health:

   - Monitor your battery health regularly through Settings > Battery > Battery Health to track any significant changes over time. Consider recalibrating the battery by letting it fully discharge and then fully charge to help the device relearn the maximum capacity.

5. Software Updates and Camera Quality:

   - Software updates can sometimes impact camera performance. If you notice a decline in camera quality after an update, you can try resetting camera settings, ensuring the camera lens is clean, or reaching out to Apple Support for further assistance. Officiële Apple Support

Even rechargeable batteries get worn down and 1-2% health loss per month is perfectly normal. Referring to the "Your battery's maximum capacity" section of the support article: iPhone Battery and Performance - Apple Support - "A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions." Apple apparently only considers it unusual (and covered by warranty) if a battery drops below 80% maximum capacity in less than a year after you receive it. Ergo, some storage loss as you use it is anticipated and acceptable. A possible 20% drop over the first 12 months equates to 1-2% drop per month being within the range of what Apple finds acceptable. "The one-year warranty includes service coverage for a defective battery. If it is out of warranty, Apple offers battery service for a charge." In other words, if maximum capacity is below 80%, the battery is below normal performance and worth replacing. A notification will appear about this. You can still use a device with a lower health percentage than 80% but for optimal usage you may wish to consider having it changed when it reaches 80% battery health.

What this basically means:

- If battery health drops a few percentage per month that is normal.

- If battery health drops below 80% before the end of the first year, contact Apple about a warranty replacement. (Apple will test it to determine its actual eligibility.)

- If battery health drops below 80% (you will see a warning message) after the first year, consider getting the battery replaced but anticipate paying for it.
