Apple has managed to improve the battery life of the Apple Watch to support 5 hours of heavy application use, reports 9to5Mac. Ahead of Monday's event, the site has heard this and other previously unknown details from sources who have hands-on experience with the wearable.
The improvement in battery life should ensure that the Watch will last a full day with mixed heavy and passive use. However, the site makes it clear that users will still need to charge the device every night, as the battery is not strong enough to last a full second day without renewal.
