    Is it bad for the phone's battery if you put the phone on the charger whenever you aren't using it, and frequently pick it up to check notifications?

    Say you are watching TV, and just put the phone down when you aren't using it. Charging starts. 1 minute later, you get a message, so you check it and reply back, and put I back on the charger. Then a minute later, another message, and you take off, and put back.

    Will this ruin the battery?

    If you are going to do that.. i'd use a cable.
    Probably not an issue, but why risk it.

    On the other hand... get a little more self control. :D
    Put the phone down and relax from time to time.

    Not really unless you want to use the phone for many years but if you upgrade every few years it should be fine

    no it shouldnt. charge cycles and temperature matters more. also it's best not to fully charge your battery.

    i have never used a wireless charger before, but have often read that there is a lot of residual heat. this may affect battery longevity.

    I do not think it will harm the battery what so ever.

    Haven't had any issues on my Android and retrofitted iPhones yet and I probably beat down mobile devices more than anyone, Apple can confirm.

    So, you should never charge your battery to 100% in order to protect its full capacity, which means you never get to use its full capacity anyway...

    Do you mean fully discharge? I’ve never heard that you shouldn’t charge your battery fully. Over charge is no longer possible.

    I "FULLY" charged my iPhone X battery every night for over a year and it still shows 100% for battery health so charging to 100% is not going to hurt it.

    Hard to believe so many "old wives tales" still surround our iPhone batteries.

    Same. Passed it on to my wife after my Max arrived and the battery health was 100%.

    it isnt old wives tales. read this: https://www.sciencealert.com/how-to-charge-phone-battery-to-last-longer-advice-science

    apple may use software to prevent trickle charge. idk, i fully charge my phone too. just passing that info along

    You just hit the nail on the head and Apple has put the technology in our iPhones so we do not have to worry. While plugged in on on your wireless charger, it will stop charging when it reaches 100%, there is no constant trickle charge.

    This is why your statement does not hold water on Apple products.

    https://www.apple.com/batteries/why-lithium-ion/

    "Your Apple lithium-ion battery uses fast charging to quickly reach 80% of its capacity, then switches to slower trickle charging. "

    The iPhones, and essentially all modern Li-ion powered devices use trickle charging to keep it in a range that is displayed as 100%. You can measure this yourself with power draw if you want to get truly scientific. The iPhone will reach it's calibrated 100%, the charging circuit will open and the phone will draw from the battery (and the charger) until a threshold is met and then the charging circuit closes to keep the battery topped off.

    I know, right !

    In any case, 100% and 0% are not actually true battery state. Apple has baked in some top and bottom end so in reality battery is not at those percentages. If you want to help your battery last the absolute longest life stay between 40% - 60%. Will get you ten times the battery life, well not you, since you not keeping your phone for ten years. The fourth or fifth owner will thank you. But who wants to keep phone that long? Who wants to have their life run by the charge state of their phone? Not me.

    Charge it any way you like, just don’t let phone (battery) get above 95F degrees. Heat kills Li-Ion batteries regardless if phone is on or off. Wanna destroy your battery? Leave phone in hot car in Arizona.

    Most of the old wives tales are part true.

    True: You should never fully charge or discharge a Li-ion battery.

    BUT! Your phone will never let you charge it to its true 100% capacity, they usually reach around 90% of their actual capacity. Same for discharging, you will NEVER EVER be able to fully deplete a battery. Most of the science papers people read are about the raw access to batteries, not how they are managed in the device.

    Use your phone, charge your phone, discharge as you like, charge how you like. Never, ever going to damage it.

    You can fully deplete a battery, just 99.9% of people won't. I had a 7 die in a drawer and I didn't pay any attention to it for about 7 months, stumbled across it and thought I had just powered it down but there were no signs of it turning on so I put it on the charger. It took about 40 minutes for it to finally kick on and even once it hit 100%, it only can hold a charge for about an hour before it takes a massive dive to about 30% then maybe 30 minutes after that it just dies outright. I could power it back up and it would come back with 85% battery for about 20 minutes then die. I killed that battery for sure because it drained to full zero.

    Like with most things, the devil is in the details. Or as Paul Harvey used to say, “and now you know the rest of the story”.

    Yup....Apple been lying to us all along. 100% and 0% reported on phone are untrue. LMAO

    Bunch of BS again that keeps the flock confused.

    I will be charging my MAX on the wireless to 100% every night and let you people worry about yours!

    I have a similar question. May I leave the phone on the wireless charger whenever I'm not using it without damaging the battery and reducing its lifespan?

    You'll be fine. I've been doing this for years. I have an X that has sat on a wireless charger for almost all of it's life and it's still holding great battery performance.

    My X was still at 100% battery health after a year of wireless all night charging so I KNOW how I will be charging my MAX.

    Everyone has a choice, use it.
