We are finding that it has to do with either active sync or the bes sync. And it is related to the number of contacts that we have in our address book which is over 6500. With no contacts pushed to the BB, the Z10 lasts for the 9-x hours that others seem to get. When we add contacts, the battery will behave some days and other days it can drain in about 20 minutes. When the sync occurs, something happens and we end up getting duplicates. 2x or 3x 6500 is a big number to be syncing. I had one user that ended up with about 10x in duplicates. Thats a big number to be syncing. Ticket is open with Blackberry. The odd thing is that it doesn't occur every day. We have swapped out the BBs in question. We have replaced batteries. Nothing cures the problem except for not allowing contact push to the BB.

Sorry I did not read all the 31 pages of posts here, but I recently got upgraded to a Z10 and had serious battery issues until today. This forum thread helped me solve my problem and I want to pass along my thanks.
Battery would last about 5 hours with all possible power savings measures taken. No wifi, bluetooth, reduced to 4G not LTE, minimum backlight, etc. The phone got hot on the back, a sure sign battery power is being wasted. I got a second battery and tried it, same result. OS = 10.1.0.4181
One of the earlier posts here said you must format your micro-SD card on the phone. I had moved my SD card from my old Torch (which I loved) as a way of transferring the data. So I backed up the data last night and formatted the SD card on the phone.
THAT FIXED THE PROBLEM !!!
I now have dramatically improved battery life. Today I started out at 100% and at the end of the day still had about 80% with light use.
Thank you to the other contributors who gave this suggestion. I am a happy BB guy again!
