    I like to stream music and listen through Bluetooth at work. I leave it plugged in almost all day so that when I leave it has a full charge. Is that bad? I also leave it plugged in while I sleep but that is usually only for about 5 or 6 hours.

    This might be helpful:

    "Some portable devices sit in a charge cradle in the on position. The current drawn through the device is called the parasitic load and can distort the charge cycle. Battery manufacturers advise against parasitic load because it induces mini-cycles. The battery is continuously being discharged to 4.20V/cell and then charged by the device. The stress level on the battery is especially high because the cycles occur at the 4.20V/cell threshold."

    A bit off-topic but I seem unable to get the phone to 100%.
    It is stuck at 99% for much time. Any ideas about it?
    I searched for it but didn't find any solution. Rebooting didn't change anything, I have the original charger, no ROMs etc.
    How much time should I wait for?

    Have you tried charging it with the phone off and then checking the level? Past problems like this that have been cited ranged from bad charger, bad battery or just the phone's properties. How is your battery life in general.

    Very good battery life, I'm impressed (although I have the phone for a few days).
    It finally reached 100% after some time. I'll keep an eye on it.
    I also installed a hefty number of apps today, plus Nova Launcher and I want to see if the battery performance will deteriorate a lot in the following days. If so I may be going back to Sense.

    How about using chargers from other phones? I have a bunch of different devices & locating the charger specific to each one can be tedious.

    I would think that as long as the voltage was the same and the charger was meant for lithium batteries it would work. I have several charge and I grab what's available for trips. They all work fine.

    Simple Guidelines for Charging Lithium-based Batteries

    A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.

    Charge at a moderate temperature. Do not charge below freezing.

    Lithium-ion does not need to be fully charged; a partial charge is better.

    Chargers use different methods for ready indication. The light signal may not always indicate a full charge.

    Discontinue using charger and/or battery if the battery gets excessively warm.

    Before prolonged storage, apply some charge to bring the pack to about half charge.

    Over-discharged batteries can be boosted to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.

    Charging Lithium-Ion Batteries
    I use my phone as an alarm clock, so I always leave it on while I charge it overnight. How much of a difference is that going to make long term verses powering the phone down to charge? Just curious!

    And I've heard a couple people in here say, "charge it anytime you're able to," and yet others say, "don't leave it constantly charging," or something along the lines of that. Is it better to let the phone drain to about 50% or so before charging again? And is it still a good idea to let the first charge have to completely drain to 0% before charging again?

    If you click on the link in the post you quoted there are other articles. There is one about how to keep lithium batteries healthy or something to that effect. The tldr is the less deep and less often a battery is discharged the better. Charge often. No, never let the battery hit 0 if you can. This is one of the worst things you can do for battery life.

    Makes sense! So the less deep would indicate charging even at 80% or 90%, but less often would indicate waiting till it's lower than that? Right? Sorry for the stupid questions, I just don't want to have a terrible battery life in a year! I can already see I'll be investing in a car charger and be one of those students who camps out on campus by an outlet with their phone charger...

    Less often meaning the less often the battery is discharged to any level. Charge as often as you can. If you have long periods where it is difficult to access an outlet I suggest investing in an external battery pack. I presently use a Solio which can be recharged by the sun but I'm looking at one of the Anker packs for a smaller device when not doing outdoors things.

    No, this is not a good idea. Dont let your phone for charing more than 8 or 9 hours.
    Since that's in contradiction to every expert and conventional wisdom, could you elaborate on the reasoning of this?

    Edit: Same question to the post following this one too.

    If you're gonna have your next phone in the next 1 year time, then shouldn't be a problem, if it's for long term use then don't charge it this way. Non removable battery needs more care than a removable. If you're on a S4 then go ahead with overnight charging habit.

    I agree. However, according to the expert everyone is quoting, charging your phone while you are using it for extended periods is a bad idea. For example, letting it sit in the charger all day at work while listening to music is detrimental to the battery. Charging it overnight or any extended period of time is fine if the phone is idle. That's what the expert says but I think it makes sense from a layman's point of view as well.

    For the record I don't think I ever said to charge while using, but sometimes this is almost required, like while driving and using nav/music. If you are using both you kind of have to plug the phone in to keep it alive. Despite this situation not being ideal I'm willing to bet it's less harmful than letting the phone get low before charging. Also more convenient since most people want their phone to work after getting to their destination. I'd be willing to bet just streaming music at your desk is far less harmful than the before mentioned scenario so I'd say it's probably Ok to keep it plugged in for this purpose. As far as overnight I think it's settled that that is perfectly fine to do.

    Hey I wasn't referring to you. I meant the guy you referred to in a post some time ago. Sorry for the confusion. See post #26 for his comments on the negative effects of charging and using the phone at the same time.

    edit: and I agree with the overnight thing.

    I knew it wasn't aimed at me. I was just saying that while it's true charging while using is sub optimal, it's still probably better than not charging while using and letting the battery get very low. My suggestion to any person who wants to have the phone doing something for extended periods should use it off the charger for a short period then plugging it in again when it's gotten to like 75% battery or something. That's probably the best practice to maintain battery health in a constant use situation.

    I recently in the Asus forum asked if the slightly faster charger for my Transformer tablet could be safely used for the phone. The basic answer was yes, that the battery might get a bit warmer while charging, but basically no problem; yet, it was indicated, it was still preferable to use the phone's charger and only swap them "in a pinch." The difference between those two is not vast, though. I'd be careful about something that charges up the phone wayyyy faster than expected.

    The One will not draw more current than 1 amp so using a higher rate charger will do no harm so far as I can tell, as long as the charger is meant for phones. Another myth is charging creates battery heat. The opposite is actually true. Discharging a battery is the biggest source of heat in a phone which is why they heat up when charging and using but not just charging.
