Welcome and thank you for reaching out. 🤗
It is normal for battery health to drop slightly, and the decline isn't always linear, it can remain steady for a while and then drop a point or two quickly.
At 260 charge cycles, a battery health of 96% is actually performing well within normal expectations.
Apple generally considers the battery healthy as long as it retains 80% of its capacity. You typically only need to consider contacting Apple Support or replacing the battery if the health drops below 80% or if you experience unexpected shutdowns or significant performance issues.
Understanding Battery Health
Lithium-ion batteries chemically age over time, which naturally reduces the amount of charge they can hold.
- Non-Linear Degradation: It is common for battery health to stay at a certain percentage for months and then drop a couple of percent in a short period.
- Charge Cycles: Apple designs its newer iPhone batteries to retain up to 80% of their capacity after 1,000 full charge cycles. At 260 cycles, your battery is performing exactly as it should.
- When to Seek Service: You generally do not need to worry about your battery unless its maximum capacity falls below 80% or if you see a "Service" warning in your Battery settings.
Tips to Maintain Battery Health
If you want to slow down battery degradation, consider these tips:
- Avoid Extreme Heat: High temperatures are the biggest enemy of lithium-ion batteries. Try not to leave your phone in direct sunlight or a hot car.
- Use Optimized Battery Charging: This feature helps reduce the wear on your battery by learning your daily charging routine and waiting to finish charging past 80% until you need it.
- Avoid Heavy Use While Charging: Playing intensive games or streaming video while your phone is plugged in can generate excess heat, which accelerates battery wear.
