Extend your battery life....quickly!
No apps of turning all controls off. Here's what I did for the past couple weeks and really, really helped add hours of life.
-turn notifications to SILENT. That's it.
You can turn just your ringer on, which is most essential. But think about it, most of us check our phone to simply check our phone. How long does a text or email ever go without us obsessively looking? And the red flashing light will tip you off if you aren't looking.
I couldn't believe how much battery the notifications used. Even flipping the screen off and on used less power. TRY IT.
Btw, I'm using my z10 on vzw if it matters. Use a lot of music streaming, email, tons of texts and air amount of web browsing. I went from 3/4 of a day (7am-7pm) to a full day plus.
