Charge and maintain your iPad battery
Find out how charging and using your iPad in ideal conditions can prolong your battery’s lifespan.
About your battery’s lifespan
A lithium-ion battery’s lifespan is related to its chemical age. A combination of temperature history, charging pattern and other factors cause chemical ageing. With increased chemical ageing, the amount of charge a battery can hold diminishes, reducing peak performance and battery life.
Your iPad works to provide the best possible performance automatically as the battery ages chemically. Your iPad monitors its power needs and manages performance to address those needs.
While performance effects are reduced as much as possible, battery ageing may still lead to noticeable, possibly temporary, effects. Depending on the battery state and the tasks your iPad is handling, examples may include longer app launch times, lower frame rates, increased processing times, reduced wireless-data throughput, backlight dimming or lower speaker volume.
iPad batteries are designed to retain 80 per cent of their original capacity at 1,000 complete charge cycles,* depending on how they’re regularly used and charged. The one-year warranty (two-year warranty in Türkiye) includes service coverage for the battery in addition to rights provided under local consumer laws.

How charging affects your battery
For most customers, the battery in your iPad should last the whole day. You can charge your iPad every night even if the battery isn’t fully depleted.
iPad will stop charging automatically when the battery is fully charged, so it’s safe to keep your iPad connected to a charger overnight. Charging resumes automatically if your battery level drops below 95 per cent.
When possible, unplug your iPad after it has finished fully charging.
A battery warms up as it charges, which can reduce its lifespan. To reduce the effect of heat and prevent overheating, iPad will reduce the charging current gradually as the battery approaches full charge.
Reducing the time your iPad spends fully charged will reduce the wear on your battery. With iPad Pro (M4) and iPad Air (M2), you can choose to limit charging at 80 per cent, which can help prolong your battery’s lifespan. When you choose 80% Limit, your iPad will charge up to about 80 per cent and then stop charging. If the battery charge level gets down to 75 per cent, charging will resume until your battery charge level reaches about 80 per cent again. You can enable or disable this feature in Settings > Battery > Battery Health.
With 80% Limit enabled, your iPad will charge to 100 per cent occasionally to maintain accurate battery state-of-charge estimates.

How temperature affects your battery
iPad is designed to perform well in a wide range of ambient temperatures, ideally 16°C to 22°C (62°F to 72°F).
Avoid using or charging your iPad in ambient temperatures higher than 35°C (95°F), which can reduce battery lifespan permanently.
When using your iPad in a very cold environment, you may notice a decrease in battery life or that your device stops charging. This condition is temporary; when the battery’s temperature returns to its normal operating range, its performance will return to normal.
Software may limit charging above 80 per cent when the recommended battery temperatures are exceeded.

How Wi-Fi and Bluetooth affect your battery
Wi-Fi and Bluetooth are designed to draw minimal power from the battery when they aren’t connected to a network or accessory. For the best experience on your iPad, keep Wi-Fi and Bluetooth turned on.
Some features may not work if you turn off Wi-Fi or Bluetooth
* A complete charge cycle is normalised between 80 per cent and 100 per cent of original capacity to account for expected diminishing battery capacity over time.
