Why You Shouldn't Charge An iPhone To 100%

Many iPhone users like to charger their device to 100%. Likely since it’s a satisfying number that ensures your device will last as long as possible. But it’s not something Apple says you should do on a regular basis, and I’ll explain why in this video.

There’s almost no real way to keep yourself from charging your battery up to 100 percent. I think depending on what kinda day is ahead of you charging to 100 percent makes perfect sense to me.

I would rather spend money on replacing the battery when its health goes too low for peak performance than take care of it like a baby.

I used an iphone 7 from november 2018 to January 2020 and all the time i charged it to 100% with the battery condition never dropping the 86% that already had when i bought it second handed. Now i have a new 12 and i find it crazy to use it between 80% and 40%. I bought the phone to enjoy it, not to stress myself

Remember also that extreme temperatures can cause battery degradation too, so if you can avoid it don't use your phone too much in direct sunlight, don't bury it under snow etc. At the end of the day you're more than likely to buy a new phone at some point in the future so just enjoy the devices you have whilst you have them and don't worry yourself about it. I got an M1 MacBook Pro and was very concerned with battery degradation for the first week or so but then realised that everything ages and there's nothing you can do to prevent it, plus it gets in the way of your enjoyment. Also, you can get a battery replacement if you have to. :)

Agree, my battery health is still at 100 % after almost a year on my 12 pro max using the same method you mentioned in your video. 👍🏽👏🏼

They need to give us an easy way to keep the max battery capacity while charging. I'd love to be able to use it plugged in at ~80% while at home by a computer.

[louistnay]

If we keep the battery percentage between 20% and 80%, it will be like we’re using a battery that has 60% of its capacity from the day we bought it. Doing this will be more of an inconvenience than a decreased battery capacity over time.

[vamos]

Basically, what he said in the video is right (kinda).

Don't use your phone extensively when it's below 20%. That will most definitely degrade the battery. Because your battery at this stage gets really hot as it pushes to deliver power.
But it's perfectly fine to charge it to 100%.. but just don't leave it plugged in at 100%. That's exactly what optimized battery charging tries to prevent.

[equivalentexchangeisalie]

This is bordering on OCD or something. Charge your battery when it's low and take it off when it has enough or 100%. Meticulously checking to make sure it's never below 20% or above 80% everyday for 2+ years is a massive waste of time and thought.

[tristanskylark]

They should add a feature 90% charge limit

[mijko]

To my knowledge, there is a software built in that makes sure you don’t overcharge the device. Also, the biggest issue is heat that generates when you charge the phone. That is what’s killing the battery. If you charge more often for shorter periods, you should be just fine. I’m charging mine to 100% every day. I’ve seen people with multiple devices to achieve better battery performance doing it that way rather than playing and babysitting a phone.

I love that this channel takes a question and makes a really thorough explanation video and yet they are only about 3 minutes long while other channels would take 10-20 minutes full of unasked extra info and ads to answer the same question.

[Rolandfart]

It seems counter productive to only charge your phone to 90 percent because you don't want to degrading down to 95 percent. You've basically just dropped it's max capacity to 90 percent because you're scared of it degrading.

[ollimustonen]

My daily routine is almost perfect for battery longevity. I usually end my day with 30-40% left and charge at the morning while eating breakfast about an hour. Usually charge is at 95% at that point. My iPhone 11 Pro has 100% battery health after one year.

[raytsh]

I always charge to 100%, everyday even (I plug in no matter the current battery percentage), and my iPhone X is still at 93% after about 4 years. That's perfectly fine for that amount of time.

[david_v.]

My iPhone 7+ has been charged to 100% every single day for the last 5 years and it has received very heavy usage. The battery capacity now reads 92% so it's doing extremely well for a 5 year old phone

[vyeewxt]

I have always charged my phone up to a 100% every time, but sadly the battery health decreased to 80%, this was perfect timing Greg!! I literally took my phone out of the charger at a 100% and then I take it out to see you posting a video about this mistake, I’ll keep note of this in the future

Edit: omfg 179 likes!! I’ve never got this much my whole entire life

Edit 2: wow Tysm people 182 likes is just too much to me ty

Edit 3: omfg u people r just too sweet to like Tysm!!!

Edit: 🤩 I’ve never in my life had so many likes

[MapleEmpire]

Thanks Greg from now on I’ll try not to charge my iPhone to 100% even if it triggers my OCD lol

[matatoto]

For really casual users this is doable to finish the day with just 40% of your battery drained out. But for people who work with their phone, or uses the camera or consumes a lot of social media, it's practically impossible to achieve those numbers, which means this is impracticable. The best advice to take care of the health of the battery is to avoid keeping the phone under hot conditions, specially when charging (cause the charging process already heats up the phone).

[specterlocators]

I regularly charge up to 100% since I have an iphone and in 3 years I still have 96% battery. I think it's not exactly a problem in charging but how you use the phone.If you sleep on the phone all day then it is no wonder that the battery life is drastically reduced in two years regardless of charging.The main problem with dying% battery is the owner of the phone.
