Thxs for the Tip. When i purchased the phone from ebay the seller had mentioned there maybe a issue with the phone, as he had a draining battery issue, he said he replaced it with a brand new battery but the issue persisted which was great for me as i got it well below what others were asking for it. I had thought that switching to /e/OS would fix the battery as more app in the android had the google trackers etc. Battery has seen no change and still drains quick even with killing background apps in /e/OS. So must be the phone. Battery reads as healthy but drains from 80% to 2 percent by the following morning. Anyways it not a bother to me, i only use it for the dreaded whatsapp and riot messenger and light web surfing.
