APPLE WATCH SERIES 4 - BATTERY LASTS ONLY FOR 6 hours after a full charge

Hi,

Really, your watch should last longer than 6 hours on regular use, unless there’s multiple workouts throughout the day.

To be fair, there aren’t a lot of components that could be faulty to the point of draining battery... If all sensors are there, and the battery is in good condition, that’s pretty much it regarding hardware tests. If you’ve sent it to Apple and they’ve returned it to you, it means they’ve ran diagnostic tests on your watch and couldn’t detect any hardware issue.

This means there must be something on the software/settings/apps eating away a good battery during regular use, and it might be a bit difficult to spot it.

I’’d recommend having a careful look at these two links, with plenty of tips on increasing battery life:

And here are some personal recommendations from the top of my head if you wanna have a look:

• Make sure both the watch and the companion iPhone are updated to the latest OS.
• On the watch app, on General settings, tick off Background App Refresh for apps you don’t use that often.
• Also on the watch app, make sure you have wake on tap set to 15 seconds instead of 70s.
• Turn off Listen for Hey Siri on the watch app.

Good luck,

To understand Apple Watch performance and its relation to your battery, see:

Apple Watch Battery and Performance - Apple Support

“Battery life” is the amount of time your device runs before it needs to be recharged. “Battery lifespan” is the amount of time your battery lasts until it needs to be replaced. Maximize both and you’ll get the most out of your Apple devices, no matter which ones you own. See the "Tips for Apple Watch" section in:

If the battery drains too fast after an update, see the replies to:

Update 6.2.1 Battery Draining Too Quickly… - Apple Community

Same issue

My series 4 watch battery life changed drastically after a 7.0 upgrade , what’s up?

Some Apple Watch users have found if they un-pair the Apple Watch, and then re-pair back to the iPhone, this helps.
