    Hello people I usually drain my iPhone 7 from 100% to zero at certain days I forget to bring my charger and I charge it 4-5 hrs later when I get home will that damage my battery ?

    Yes.
    That could cause permanent damage to the battery fluids and if it needs a jump the alternator could get shorted out.

    Short of physical damage and exposure to temperature extremes, there's very little that a user can do to really harm modern Li-ion batteries. Change and discharge however you like.

    It will just count as one cycle as far as wear goes. The battery only has so many cycles before it starts to degrade.

    In past post you have said that you charge your phone 3-4 times a day. Do not see any benefit in doing a complete discharge just for the heck of it, but it will not kill your battery as Apple has built technology into their phones to keep the user from really discharging it completely.

    Is this you new replacement iPhone 7? If so hope it is perfect!

    Batteries are meant to be used. That is why they exist.

    Settings > Battery

    Take a look at battery usage. Apps near the top are more likely.

    You can see what apps used to power in the settings for your phone.

    20% overnight is too much unless your phone was doing something in the background. My 7+ uses maybe 3-5% ov er night but then I have excellent cell coverage.

    You have had several iPhones, did they drain that much?

    I'm not sure what you're trying to say. If Facebook and messenger are at the top of that list, that's where I'd start looking.

    The battery life on my 7 is on point with my 6s+. Apple doesn't really let you drain all the way down, just to a minimal acceptable level. With the latest advances in batteries (ignore those guys over at Samsung for a min), there's little you can really do to hurt your phone's battery cycle - partial charges, complete drains....

    What kind of cell coverage do you have. Very poor cell coverage can eat a battery quickly. Sit you phone where it sleeps and look at the cell coverage strength.

    That is not real good and could explain part of the problem. Have you had just 4G before. When I am in an area with 1-2 bars 4G it would eat a good more battery. One of my customers is out in the sticks and when I spend a day there I use much more battery.

    At my house and office I am 3 bars with LTE.

    It would not hurt to delete Facebook for a day or two to make sure it is not the problem. I do not do social media but friends of mine say it eats their battery up like crazy.

    Sounds like you are not in a real strong cell coverage area and that can hurt your battery trying to maintain a good signal. Also Facebook if given freedom will clobber your battery.

    As an experiment, that might be a good idea. ALso, as someone else pointed out, you may be running into the battery issues due to your coverage. My phone typically gets better battery life when I'm connected to Wifi. I'd give that a try if it's an option.

    Actually, is there a reason you don't plug your phone in and charge it overnight?
