Apple's (AAPL) - Get Apple Inc. (AAPL) Report next slate of iPhones could have higher battery capacities and wireless two-way charging, according to respected Apple analyst Ming-Chi Kuo.

Kuo, an analyst at TF International Securities who's known for prescient calls on Apple's plans, wrote in a note on March 31 that Apple would release successors to the current iPhone XS, XS Max and XR.  "Battery capacities of new 6.5" OLED, 5.8" OLED and 6.1" LCD significantly increase by 10%-15%, 20%-25%, and 0%-5% compared to last year's new models," he wrote.

Apple shares were rising 1.45% to $194.02 a share in morning trading on Tuesday. 

Short battery lives are something some iPhone users have been unhappy with, and the upgraded batteries could add to the value iPhone users expect when they buy Apple's higher-priced smartphone.

The new batteries may also posses a two-way wireless charging capability, according to Kuo, allowing users to put their other Apple devices, such as Apple Watches and AirpPods on the back of the iPhones to charge those devices. Samsung (SSNLF) and Huawei have both introduced this feature for their devices. 

"This new function could make it more convenient for users to charge the new AirPods and create a better integrated user experience of the iPhone and AirPods," Kuo said. 

Apple shares are up 21.6% year-to-date.
