By the way.. Don't get hung up on percentages... Your phone doesn't care about that number, it cares about voltage. There's a floor where if the battery hits that voltage, the phone will turn off. What's going on is that the power supply can no longer provide a constant, regulated voltage at that level, so rather than have everything tweak, it powers down. The damage point of these cells is a lot lower than when the phone shuts off.

Mine drops out at 5%... Some might be higher, some lower.

I don't follow any battery charging rules... I just charge whenever I can and rarely run the thing down to the stops.

The issue is that you're letting the battery drop below 40% - you might as well cut it in half. If you want a lithium battery to last, never let it get below 40% after conditioning it. (50% is the sweet spot for maximum lifespan.)

The phone is set to shut the phone off at 10% charge. If you then turn it on, it's at 10% (or lower) charge and shuts off. That's how it's supposed to work. (That's a "last call before you destroy the battery" notice, it's not something to do all the time.) (There are ways to set the shutoff lower, but that just destroys the battery faster - and in a phone with a battery you can't replace by just popping the back cover off, that's not something you want to do. You want the battery to last at least until you decide to get rid of the phone. (Dropping it to 10% every day will kill it in less than a year.)

Wrong. All batteries go through an effect called conditioning. this effect is simply causing cells to degrade due to not being able to discharge. While yes Li batteries tend to not show it as much it still will effect it. for example if you go for one month of charging your batteries when they hit 50% and you only charge it once a day then that is 30 cycles each taking away .05% of your battery charge capacity. therefor after one month of that you have removed 1.5% of your batteries max capacity. after one year of that you are now looking at 18% reduction. the only way to fix this issue is by 0% discharge with a trickle charge to get it to 100% until it returns to correct state, however keep in mind that if a cell can't charge for a long period of time the cell will corrupt and become unchangeable. I had a laptop Li battery that would hold roughly 10 mins of charge that after doing this I managed to get it to hold a 24 hour charge, which was 50% of the battery's power on time. I have done the same thing to over 20 different phones and I work on systems using various battery types with Li batteries being the most common, and FYI my droid turbo still runs normal power on time for the battery type and size after one year of being in service.

Edit: in case anyone is wondering 0% doesn't mean 0Vdc with batteries, it means the voltage dropped below usable levels.

well the n6 doesn't run like a moto, it runs like a nexus. It doesn't support any moto specific app, or for the main part have any moto features. Not to bash on the N6 or anything. That's the phone I have.
