Get the most out of your battery with these tips:
Adjust your Location Update Schedule in the Angel Watch™ app.
The most impactful way to improve battery life is to change the Location Update Schedule of the watch in the Angel Watch app. The more frequently the watch forces the location request from satellites and cell towers, the quicker the battery will drain.
For most normal days, it should be sufficient just to keep this on 'Manual Mode' allowing you search for the watch's current position on-demand.
If you have occasions where tracking history and geo-fencing are required, such as your child bicycling around the neighborhood or out at in the park, you should have this set to refresh the watch's location more frequently.
Try also reducing screen brightness and keeping video calls to a minimum should you require the charge to hold as long as possible.
Avoid full battery drainage.
When you notice the watch's battery is low, plug it in as soon as possible. If you consistently allow the battery to deplete to 0%, over time your watch's battery will degrade and will not hold a charge as well
Don't leave your battery depleted for long periods of time.
When the watch battery is left dead for long periods of time they risk entering a state of discharge. This will make it difficult for the battery to hold a charge in the future. Charge your Angel Watch to 50% for long-term storage. The healthiest charge for a lithium ion battery seems to be about 50%. If you are going to store your Angel Watch for an extended period, charge it to 50% before turning it off and storing it. This is easier on the battery than charging it to 100% or letting it drain to 0% before storage. It would be best to turn the watch on every several months and top the battery up to 50%.
Avoid extreme temperatures.
Like most batteries, the smart watch's battery shouldn't be exposed to extreme heat or cold. Temperatures reaching over 95° F (35° C) can permanently damage the battery by decreasing its capacity. Colder temperatures may temporarily decrease your battery's performance. The Angel Watch battery's optimal zone lies between 62° to 72° F (16° to 22° C)
