Zwift's graphics use a lot of power, and you may see your battery drain more quickly than you expect. There's a number of ways to reduce the power consumption, though:
- If you are running it while plugged in, use a nice cable. The official Apple cables work every time, while many of the knock-offs we test at Zwift HQ barely charge our devices.
- Use an iPad charger, not an iPhone charger. iPad chargers are larger and put out more power.
- Turn screen brightness down a tad.
- Turn on the battery saving setting (in-game Menu > Settings > Battery Saving)
Following these guidelines will reduce your power consumption, and many devices will stay at 100% charge the entire time you Zwift if plugged in with the tips above.
