If you use facebook and the facebook-messenger try to remove these apps cause they alway scan YOUR DEVICE permanent for NEW Files and watch for YOUR updated DATA. These Apps CREATE Indexes and upload this to the dark Facebook Cloud Servers. This kills your battery capacitiy!! mostly 50% of online time!! and destroy’s your PRIVACY! and blow up your ROM at your Mobile Device
- Use a small browser like builtin webview of Android or firefox
- Enter http://m.facebook.de to connect yourself to the fb-network
- This saves much energy and you are NOT permanent scanned!!
Try and test it one week, i did with two identical phones and was impressed about the results
