Samsung s7 battery saving tips Bluetooth#
Disable this if you don't use Bluetooth devices, and if you do ( I do, too), it isn't a large enough battery sink to worry about.Ĭonnections > NFC and Contactless Payments I'd suggest trying this yourself and seeing if it affects your everday usage (as it can in some cases).īluetooth - medium battery saver - Bluetooth can use a large amount of energy, especially when it's constantly syncing to devices like watches, earphones and speakers that trade large amounts of data.
Wi-Fi power saving mode - ( Enable ) - potentially large battery saver - Looks for patterns in Wi-Fi usage to learn when it's best to turn on Wi-Fi power saving. If you only join trusted networks, disable it. If you often join different hotspots, leave this setting on. With this disabled, mobile data will need to be manually turned on when your Wi-Fi slows/drops.ĭetect suspicious networks - very s mall battery saver - Checks newly joined networks for suspicious activity. Switch to mobile data - very s mall battery saver - Your device periodically checks if Wi-Fi can be found, and if it can't, mobile data is turned on. Disabling these settings helps battery life unless stated otherwise.Ĭonnections > Wi-Fi > 3 Dots (Upper Right) > Advanced The options you choose to disable (and enable) below should allow you to enjoy your device as much as possible as well as for as long as possible.Īll of these settings can be found in the Settings app (from app draw or from notifications panel). If there's something that I rarely use that could be disabled to increase it, I'd prefer to disable it. If there's something I often use that could be disabled to increase SoT/standby, I'll leave it enabled. Disabling everything to improve battery takes the fun away from having such a powerful device - striking a good middle ground between better battery and great features is what I always personally aim towards.
This post is here to hopefully help level the playing field by giving a detailed list of what can be changed to improve battery life. Truly bad batteries are rare but they do happen.
If this post doesn't help improve your battery that feels substandard, contact Samsung. In general, most people are more than happy with the S21/+/Ultra's battery performance ( me included!), with the average being from 5 hours to 7 hours SoT. So, if you see others with much better/worse SoT, it doesn't mean you have a golden/lemon device - it's more likely that you just use your device differently. Comparing battery life, including SoT (Screen on Time) between two people doesn't work unless you're both doing the exact same things with the exact same settings for the exact same amount of time. Battery life is going to massively differ between people due to what apps are being used - something as simple as browsing the internet can hit the battery more than video consumption, and any kind of gaming will kill the battery even quicker.
