There is definitely a bug with software, the idle battery drain is too damn high. To make it worse, the phone struggles to even give a screen-on time of 3 hours now and refuses to charge till 100 even with the supplied charger. One of the most peculiar thing i found out was my phone died due to battery drain, i connected it to the charger and booted it, and suddenly the battery is at 56% ?! Can someone please fix this? It's a very serious issue considering the times that we are living in!
Please follow below steps may improve battery backup: 1. Enable “Power saver” (Settings > Power management) 2. Close apps that are not used (Bluetooth, WiFi, GPS, etc.) 3.
