Charge and maintain your iPad battery
Learn 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 aging. With increased chemical aging, the amount of charge a battery can hold diminishes, reducing peak performance and battery life.
Your iPad automatically works to provide the best possible performance as the battery chemically ages. Your iPad monitors its power needs and manages performance to address those needs.
While performance effects are reduced as much as possible, battery aging might still lead to noticeable, possibly temporary, effects. Depending on the battery state and the tasks that your iPad is handling, examples might 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 percent of their original capacity at 1000 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 automatically stops charging 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 percent.
When possible, unplug your iPad after it has fully charged.
A battery warms up as it charges, which can reduce its lifespan. To reduce the effect of heat and prevent overheating, iPad gradually reduces the charging current as the battery approaches full charge.
Reducing the time that your iPad spends fully charged reduces the wear on your battery. With iPad Pro (M4) and iPad Air (M2), you can choose to limit charging at 80 percent, which can help prolong your battery's lifespan. When you choose 80% Limit, your iPad will charge up to about 80 percent and then stop charging. If the battery charge level gets down to 75 percent, charging will resume until your battery charge level reaches about 80 percent again. You can enable or disable this feature in Settings > Battery > Battery Health.
With 80% Limit enabled, your iPad will occasionally charge to 100 percent 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 62° to 72° F (16° to 22° C).
Avoid using or charging your iPad in ambient temperatures higher than 95° F (35° C), which can permanently reduce battery lifespan.
When using your iPad in a very cold environment, you might 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 might limit charging above 80 percent 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 might not work if you turn off Wi-Fi or Bluetooth
* A complete charge cycle is normalized between 80 percent and 100 percent of original capacity to account for expected diminishing battery capacity over time.
