Apple Watch to get battery life boost with HMO instead of LTPO OLED display

According to Apple, the Apple Watch Series 11 ($329 on Amazon) achieves a battery life of 24 hours instead of the 18 hours that older models were supposed to achieve. However, this "upgrade" was only achieved by Apple bought by a trick. In practice, the battery life is hardly any longer. So if you want a longer runtime, you currently have to either go for the much larger and more expensive Apple Watch Ultra or a smartwatch from another manufacturer.

This year, the Apple Watch Ultra 4 in particular is set to receive a new design, while the Apple Watch Series 12 is said to mainly benefit from software improvements. According to a new report from The Elec the Apple Watch could finally get a longer battery life in 2027. This is because LG Display is currently developing a High-Mobility Oxide (HMO) TFT. This HMO OLED panel is intended to replace the LTPO OLED display of future Apple Watches.

As LG Display will initially produce these panels in very small formats, the Apple Watch is the most likely product from the iPhone manufacturer to benefit from this technology first. HMO is said to have one major advantage over LTPO: lower power consumption. It is still unclear when exactly the first HMO OLED panels will be delivered. As LG Display has not yet validated the panels for mass production, the displays will not be available for the Apple Watch Series 12. At the earliest, the panel might be ready to ship as part of the Apple Watch Series 13, which is expected to be launched in September 2027.
