My Lumia Battery drained Quickly! 30% in 2 hours! Low brightness and glance screen off! So there are a problem? The phone run in windows 8.1 Lumia cyan
First, reboot your phone. Check your background apps (settings>battery saver), and see if there's anything fishy in there. Take a look-see if the network coverage around your area is unsatisfactory, and so on.
me too. what should i do. i dont have whatsapp though. i just browse the internet and it takes 1% per 3-5 minutes with wifi on and no data connection however my network coverage is low (3 out of 5). battery saver on, no glance screen, no double tap to open, brightness is low.
