Im having some questions about my A40 battery that i dont really have nothinf to compare about.
My phone is lossing 1% at every 10 minutes of low use ( keep in mind i have basically all apps suspend for no background activity) . When im playing , like lets say , hearthstone , my phone really drains quickly like 4 - 5 non stop gaming.
In general my a40 with normal abuse gets about i would say 5 hours of screen time.
Keep in mind that the a40 version has the samsung processor wich has worse effecienty.
