Currently this phone is refurbished.
Lately I tend to notice that my battery level will go from like 30%-31% ish to 19-20% in one fell swoop
Using the device at the time, yes...Dependant on the application? Doubt it. It would be very very hard for me to use the exact same app at the exact same time of seeing 30-20%
Anyways so what I did was put AC charger from 18% to 26%; I then peformed a Factory Reset
*I retreived my contacts
*I set up my Google
*I changed Mobile settings from Global to LTE/CDMA (or whatever); and I chose "allow all trips"
*I launched Google Play and downloaded a % by % battery app called "battery HD" by smallte.ch
After all done I was at 33%; currently as this sentence is being written...31% we will see
After the drop in battery though, during charging...this battery app goes up..tick by tick....21%, 23%, 24%, etc etc
And of course the default Battery app dont help as it always registers by 10%
But I'm also avoiding using the device outside of just keeping device screen lit so I can see it go from 30-20.
I will let you know but....thoughts???? 30% now as I just wrote this sentence; so very very soon I will see if it drops to 29% and 28% in which there was an app installed causing it to do that; or if the device itself is bad
