Do you charge yours every night?

    It's been over a week now, and I've discovered that a full day of use with my Watch (42mm Space Grey Sport) only depletes my battery down to 50-60%, taking my watch off the charger at 9am and wearing it until 11pm or so in the evenings.

    Is it good practice to charge it overnight anyway, or let it deplete down once in a while? Twice now I've let it run through the night and it will last me a good day and a half before finally running out of juice.

    What are your charging habits so far?

    I received my :apple: Watch yesterday :) out of the box it had around 72% charge and i set it all up at about 2pm yesterday (UK time) i ended up using the Watch on and off until i went to bed at around 11:15 last night, it had 14% left.

    I'm assuming it's ok to leave the Apple Watch on charge throughout the night? even tho it only takes around 2 hours to charge.

    No matter what I end the day at the watch goes on the charger before I go to sleep and I take it off when I get up and start the day at 100%.

    I usually have 25-50% left at end of day, depending on if I worked out that day.

    It's just easier for me to charge it every night. I do the same with my iPhone and it often has 60% charge left or more. The routine of every night is easier than trying to remember to check to see whether it needs charging on a particular night.

    I've been charging every night and it hasn't been a big deal. Today was the first day I didn't wear the watch and it was at 80% after roughly 24 hrs without being paired or used.

    Charge mine every other night, after 2 days of use I'm on 5-10%, that's with a 38mm :)
    I found that turning stand reminders and activity progress updates off gave me an extra 10% per day, meaning I can stretch it out over 2 days now :)

    Do you charge yours every night?

    Right now it goes on the charger every night. However, I will put it on the charger before the shower and put it back on immediately if an AW sleep monitoring app is developed -- not the iPhone apps that are already out.

    For lithium battery, keep it full is one of the easiest action to maintain it's performance.

    Fully drain a lithium battery is one of the worst thing you can do to the battery under normal situation.

    It's not Ni-MH anymore, the old good habit is not a good habit for modern lithium battery. Just charge it every night, then your watch will be your good friend everyday,

    Good to know, so it still having 1 50-60% charge is no problem. I remember back in the day that meant the battery would "forget" certain charge cycles, but if that's not the case here then I'm set!

    I typically have <50% for a 18 hour day, so I assume I cannot make it another 24 prior to needing charging.

    I'd prefer to charge over going into power saving mode.

    i've been putting it on the charger when i go to bed. i put it on first thing in the morning. after my workout i rinse it and put it back on the charger while i shower (the battery goes down considerably during a workout! :eek:)

    then i put it back on once it reaches 100% again and wear it the rest of the day....

    I sleep with the watch on my wrist. I sleep with my wife and I find Apple Watch to be a perfect discrete personal alarm clock. When I wake up, the watch's battery is down to about 90% and I top it up while I shower, brush teeth, shave, and dress (about 30 minutes).

    Between 9 and 10 pm, I relax in the dining room or sofa to catch up on emails, watch an episode of TV, or read a book. This is also when my Apple Watch gets fully charged. It is typically down to 40-50% and in about an hour, it is charged to 95 to 100%.

    I suppose I don't need to top it up in the morning, but since I prefer not to wear it during shower, it has become a routine.

    Had mine for a week and a half so far, and with overnight charging, I'm at about 40-50% when I turn in. If I use the Workout app, 30-40%.

    Only time I ran it down to reserve mode (1-2%) was my first day of owning it, but that's because 1.) I didn't charge it up out of the box, came about 81% charged, and 2.) I played with it a lot and initial set up.

    Suggestions about how to care for lithium ion batteries are just voodoo at this point. There's just too many technologies and implementations. I would just trust the intelligence of the charging circuitry and charge whenever is convenient.

    Nope, full is not good either. Ideally keep it between 20-80%.


    "How to prolong battery
    Keep cool. Operate in mid SoC of 20–80%. Prevent ultra-fast charging and high loads (most Li-ion)"

    This is what I do too. Accept I sleep with my wife not yours :D

    But you don't even know if it's at 20-80%. The charging circuits make that number up, possibly in an attempt to influence your behavior, or provide safe margins. I think it's a pretty silly thing to worry about.

    Yes we can argue about the accuracy of the numbers, but they are the best estimate we have. We cannot argue that keeping it fully charged is not ideal and may be harmful.

    "How harmful" is what one needs to know before they allow their relationship with their gadget to degrade into a never ending series of obsessive compulsive rituals.

    So harmful you won't make it 6 months without needing to send it in for service? Or an imperceptible drop in performance that a lab full of equipment is needed to detect?

    I agree with that completely. In fact, that's why I replied initially. The other poster stated that keeping it fully charged is beneficial. That clearly is not beneficial, and may be harmful.

    I'm not sure why you're arguing with me. I never said to be OCD about charging it, just that 20-80% is ideal. If you have a better source with better data, I'm all ears.

    I'm not really arguing with you. You're saying something that's true, but I'm just adding "... but it may not be of practical significance" to the end.

    Generally, I think battery management is one of Apple's stronger areas. I ran a 2010 MacBook Pro as a desktop for over 4 years, always plugged in. It was always at 100%, but whatever logic Apple uses to protect the battery worked well. I switched to a Mac Pro, and now my laptop is a laptop, and the battery stats are still within the healthy range and the life is good for that model.

    i actually sleep with mine on since i wake up at 6am for gym every morning and dont want to wake up my prego wife. I use mine, like my previous fitbit, for silent alarm.

    I just end up charging mine while at my desk during work for an hour or so whenever needed. If i see it below 50%, i just put it on charge till i am back at 85% or higher and go on with my day.

    You just described my usage exactly. I sleep with the watch on and the silent alarm has been perfect for not waking my wife. I charge it each night around 9-10pm and put it back on when I sleep. I wake up 7 hours later with 94% left which is great. If I workout for an hour or so, I charge it while I shower. No biggie since I would take it off anyway.

    So far I end each day with 40-50% left and using it way more than I expected.

    Yes I charged mine nightly every night. That worked out quite well.

    However I must say I don't miss it now that I returned it, one less tech device to maintain, my iP6.Plus with its squint free display is so much nicer...#
