Hi, I got a Blackberry Z10 from my dad. Worked fine for a month but battery has drained empty very fast since this week. I have already reset the screen brightness and so WiFi but nothing help.
In normal operation such as call, sms, and email, it last less than 10 hrs. How to fix it? Thank you.
Echoing aiharkness's post, the Z10 is a good BB but unless you keep it topped on the battery you will start to notice the battery drops quick. As with all LI battery's, if they drop below 25% a lot they show full but are not .
also check for Apps running constantly like Facebook or twitter
It is normal with a high specs smart phone like z10. Maybe try calibrating your device and use some sort of apps that helps your battery life stay longer.
