For a user using the Samsung Galaxy Watch 7, it is good news that a certain setting on this smartwatch, when done correctly, can be a huge factor in enabling the watch to last longer. This is a good tip to keep the smartwatch continuously functional without charging, especially for busy people who travel a lot.

Turn on Power Saving Mode on Samsung Galaxy Watch 7
Power Saving Mode is one of the prominent features that saves battery on the Galaxy Watch 7. In this mode, the processor operates in low power, and black and white will have a display. All unnecessary items will be turned off, and will therefore last the longest.
Steps to Activate Power Saving Mode
Settings > Battery > Power Saving Mode > Activate
This will dim your screen and turn off the last applications opened. However, essentials such as notifications, calls, and time will still run in this mode.
Deactivate Always On Display
Most users have only switched on Always on Display on their Samsung Galaxy Watch 7, which seriously drains the battery. Deactivating it will allow the screen to light up only when using the watch.
To Deactivate
Settings > Display > Always On Display > Off
This little change would improve the backup battery by 20-25%.
Disable Unused Connectivity
Bluetooth, Wi-Fi, and GPS have always been set active in the Galaxy Watch 7. But you don't need them to always be on. Turn them off whenever they are not needed.
For Example
Settings > Connections > Wi-Fi/Bluetooth/GPS > Off
Especially if you're not outside or very close to your phone, turning off Bluetooth won't be a problem.

Set Lower Screen Timeout
The more the watch is on, the quicker the battery gets drained. Cut it short: Settings > Display > Screen timeout > 5 or 10 seconds
This is a very insignificant change, but it will have a good impact on the battery at the end of the day.
These four features will greatly help improve the battery capacity of the Samsung Galaxy Watch 7: Power Saving Mode, turning off Always-On Display, turning off unnecessary connections to the device, and reducing screen timeout. Following all these little tricks, your Galaxy Watch 7 will be able to sleep for more than a full day.
