My galaxy s10 on lte gets bad battery life I've factory rest my phone and I've cleared the cache, on wifi it has a great battery life.. help
1) Go to settings>device care>battery and then battery usage, see which of the apps/services eat your battery more
2) How good is the cell signal where you experience most battery drain?
3) If you believe LTE is causing this, then go to settigns>connections>mobile networks and set network mode to something lower than LTE. It will of course lower your mobile internet speed, but this way you can test for couple of days and see...
