Screen brightness is set to minimum, when I'm out and sun glare makes it difficult to see on minimum, I set it to the lowest possible brightness I can get away with to see without having it on max (around 1/4 or 1/3 of brightness level, never over half). I have snap2chat open in background constantly, refresh time set to 60 seconds. I can charge it up before I go to bed and if I unplug it at 100% right before I go to bed, it will still be above 85% when I wake up the next day (8-9 hours of sleep).

Mine lasts 8-10 hours of heavy use on wi-fi (gaming, reddit, youtube, twitter, texting/bbm with virtually no standby time), around 10-12 hours while roaming if I leave it idling most of the time, but I can push 6-8 hours on 4G pretty easy. Please don't recommend me the Z30! I personally find its 5' too large and I feel more manageable with Z10's 4.2' along with the complementary iPhone's 4' screen. I want to know how long your Z10 lasts on a single charge, depending on your usage.

I have about 3 pages of apps (including the default BB apps), of which 5 are Android apps. I've been wondering whether sideloaded Android apps take any hit on the battery, or what else is a possible cause for such a bad battery life. My primary phone at the moment is the iPhone 5 and it lasts way longer than the Z10, even considering that it has 1,440 mAh compared to the Z10's 1,800mAh. This is such a critical hit and is a main reason why I don't use the Z10 as a primary device. If I don't charge up overnight, it isn't a surprise to wake up to the battery at 10 - 20%. My Z10 doesn't last half a day with a light use and its standby time is downright embarrassing.

However, I was so startled when I recently read about BlackBerry's advertised battery life of 11 hours on talktime and 408 hours of standby for the Z10. First off, apologies for yet another post on Z10 battery life.
