The Apple Watch ( Watch) battery life may disappoint owners of the forthcoming device from the U.S. tech giant, says an Apple fan site which claims to have inside knowledge on the matter.
Apple Watch will require daily charging
Apple has already hinted that the new device will need to be charged every day (pretty much like most other smart watches that have OLED screens). Apparently, the specific battery life targets that Apple wants to achieve have been hinted at, with the news that the first version of the watch may struggle to meet those targets.

Apple has used a fairly beefy CPU in the new device, which it calls the S1 chip (manufactured possibly in conjunction with Samsung Electronics who make the company’s Ax series chips found in the iPhone and iPad), which is very close in performance to Apple’s older A5 chip that powered the iPhone 4S (and currently powers the iPod Touch). The display drains a lot of the battery, as it’s a very high-densit OLED screen that can display at 60 frames per second – quite impressive for a watch.
Apple hoped the Apple Watch’s battery would last all day, with up to 4 hours of “active” use or 19 hours of combined “active/passive” use, 3 days of standby time and 4 days in “sleep mode”. However, 9to5 Mac’s Mark Gurman (a reliable source of Apple insider information) says the sources claim the watch will only deliver 2-3 days in standby mode.

The numbers don’t sound very impressive, but in fact the watch is not designed to be on and displaying content all the time. When the Watch screen is not active, the display is powered off to save energy. Apple has been aiming for 19 hours of mixed usage each day, but that the company may not achieve that, at least in first generation version.
Battery life concerns may also be why the Watch was announced in September but given no specific launch date, as Apple works to improve performance by a mixture of hardware and software improvements. The unique inductive charger has also been a cause for concern, as it reportedly charged the watch slower than expected – something that will hopefully be improved by the time it launches in March.
The Thai Tech team will acquire an Apple Watch at launch, and will post a full review when available.
