Using Ultra Power Saving Mode on Your Samsung Galaxy Tab A (SM-P550, SM-T550, and SM-T350)
Use Ultra power saving mode to switch your device's screen to grayscale and turn off nonessential apps so you get the maximum battery life. Location services, and connectivity features such as Wi-Fi and Bluetooth, will also be turned off in Ultra power saving mode. With Ultra power saving mode turned on, even if you're down to a 10% charge, you can receive calls and texts for up to 24 hours.* (*) Based on laboratory testing. Battery power consumption depends on factors such as network configuration, wireless service provider, signal strength, operating temperature, features selected, vibrate mode, backlight settings, browser use, frequency of calls, and voice, data, and apps' usage patterns.
