Yeah did a hard reset just after installing Cyan...Now I recharged it from 0%... It shows an estimated time of just 1day...�� ....lets see what happens...It was better in dp 8.1 os version-12397
I have the same (1 day and 8 hours). In 8.0, it was 2 days and a few hours. I have even turned off Glance, a lot of background tasks and removed BBM, but the battery is really horrible! I will try out more things, will let you know if I found the cause of the drain!
Cyan update for CV 1320 UK is out.
Whatsapp notifications are working perfect. I do not use Viber and Messenger so no idea about those.
