Screen on time?
I used to get upto 8 hours screen on time with atleast 24 hours when i had that. Its battery timings are great.
With some self performed debloating, zip aligning, kernel modifications, it even went upto 12 hours SOT, on 50% time Internet (wifi) use.
Its smaller brother Core Prime 4G has the same amazing battery timings upto 8 hours SoT easily with atleast 24 hours. This is from 100-20% charge and with ultra power saving mode off. It usually drops 10% battery in one hour of Internet browsing on wifi.
Here is the stats of phone recently charged.
