Lithium-ion battery useful tips

Lithium-ion batteries are used in most wireless devices because they are lightweight, can hold a charge, and can be recharged repeatedly. Because these batteries are more sensitive than alkaline batteries—like those used in flashlights and other household devices—they need to be treated with care.

In order to keep your lithium-ion batteries safe and improve their efficiency, we recommend the following actions:

• Follow the battery usage, storage, and charging guidelines provided in your wireless device’s user guide. Do not open your battery pack.
• Purchase chargers and accessories that are certified, approved, or otherwise compatible with your device. If you see an example of an unsafe mobile device or accessory, please report it immediately.
• Avoid damaging the battery by not crushing, puncturing, or putting pressure on it.
• Keep the device away from heat sources such as direct sunlight and cooking surfaces. Sustained hot or extremely cold weather or temperatures can also impact your battery’s performance.
• Keep the battery away from other metal objects like coins and keys because they can impact its electrical connections.
• Avoid exposing the battery to water, which could cause corrosion.
• Avoid dropping your device, which could potentially damage the battery.
• If you plan to store your device for a long period of time, keep your battery at about 50% of its charging capacity and turn the device off to prevent the battery from unnecessary use.
• Install any updates to your operating system to keep up with the latest battery efficiency enhancements.
• Do not overcharge batteries.
• Stop charging your battery if you see or smell smoke, fluid, or other odors or if your battery looks misshapen, discolored, or hot to the touch.

How to keep your LifeWatch Generation 2 at its normal operating temperature

Vyvo devices have a set temperature range, where they operate at their best. While they may feel warm under certain conditions, like charging, this does not affect the device's lifespan or performance. However, if your devices get too warm, it could cause some issues. Use this guide to help keep your devices at their normal operating temperature.

Factors that may impact temperature

Check out the Battery’s useful tips (below) on safe usage for more information.

Factors that can affect your device's temperature:

• Using your device outside of normal operating conditions, which are ambient temperatures between 32 and 95 degrees Fahrenheit.
• Placing your device on or near a heat source, leaving it in a parked car on a hot day, or continual use in direct sunlight
• Using multiple functions for an extended period of time, or using processor-intensive apps such as GPS tracking
• Charging the device with a non-Vyvo, incompatible, or defective charger (and USB cable)
• Initial setup and data transfer from a previous device
• System or firmware updates

What to do if the device feels too warm

Here are some tips for what to do if your devices warms up:

1. Disconnect the charger, and close any running functions until the device cools down.
2. Try using a different Vyvo-approved charger (and USB cable) when charging. Be sure to charge the device on a hard, flat surface.
3. Turn down the device's screen brightness, and delete unused or unnecessary files and apps.
4. Keep the device's software and apps updated to the latest software version.
5. Do not use or wear the device until it cools down completely. If the device is still too warm to touch, you should contact the Support Team.

LifeWatch Generation 2 water resistance tips

No matter what nature throws at you - whether it's rain or puddles - your watch will be perfectly fine. In other words, you can keep track of your workout when it's raining, or even underwater!

Even though your watch is water-resistant, please remember that it's not indestructible. Make sure you follow these tips carefully to prevent any potential damage:

• Whenever your watch gets wet, dry it thoroughly with a clean, soft cloth.
• Do not expose the watch to water at high-pressure levels.
• After using the watch in seawater, rinse it in fresh water and dry it. Failure to do this as instructed may cause the watch to suffer from operability or cosmetic issues.
• If the watch is dropped or receives a hard impact, the water-resistance may be impaired.
• Avoid excessive, sudden temperature changes and high-velocity activities. Falls and shocks may weaken the structural integrity of the watch.
• The watch is not intended for scuba diving.
• Your  LifeWatch has a waterproof certification of IP68, meaning you can wear it swimming in a pool or in open water to a maximum depth of 50 meters.
