iPhone 12 Pro How much slower will iPhone 12 Pro Max charge on current chargers?

[NJRonbo]

Not quite ready to jump into Magsafe for my iPhone 12 Pro Max

I already invested about $150 on the Logitech 3-in-one charger that I have been using for months now.

I know Max has a larger battery.

The Logitech charger, I believe, is 7.5w for iPhone charging capability.

Will the charging time take a hit with the newer battery on the 12 Pro Max using current (now older) chargers?

Thanks in advance

Just remember the rule of thumb. Heat is the enemy of battery 🔋. The faster your charge your phone the faster it ages. My 12 pro max will be delivered to a local Apple store on 11/13. Before this I sold my 11 pro max after one year of use. It still had 100% battery health. The only way I charged it was using the good ’ol 5w charging brick. Take it for whatever it’s worth. This isn‘t a criticism for those that do fast charge. Charge however you like. Just putting in my 3 cents

Sam,

If that's true -- and I have no reason to disbelieve you -- then that's actually very good news.

That means those of us that continue using slower charges gain battery life.

Although, for those of us in the upgrade program who get a new phone every year it's not even something we would be concerned about.

I am just wondering how much slower the iPhone 12 Pro Max will charge, say compared to an iPhone 11 Pro Max now that there is a bigger battery or will it be negligible?

Ok I see what You’re saying. I regret to inform you that the battery inside the 12 pro max is actually 300 mah smaller than the 11 pro max. Yes I know it sucks. I think for sure that the A14 can make up that small difference. We shall see. But yes, slow charging bricks are still relevant considering this fact now

Oh Wow. It's smaller. That's okay. The bright spot, as you just stated, is that the charging devices we already own are still relevant.

Thanks for all your help! Appreciate the answers.

Actually, really modern USB-C chargers like the new Anker Nano automatically throttle down the charging rate to "save" the battery as the charge exceeds 50%. I noticed the charge speed on my Anker PowerElite II 12 W/2.4 A USB-A charger slows down quite a bit after 50% charge is achieved on my iPhone 12.

You won't need to charge your Max during the day as battery life should be amazing. Just plug it in at night before bed with the 5w charger.

I am a firm believer of slow cool charges are the best way to treat your rechargeables.

Rapid, fast, hot charges are the enemy for batteries.

I upgrade each year so knocking down that capacity a bit is no big deal. I fast charge with usb c and 18w adapter

It’s 10% smaller. Size of battery has no affect on charging speeds tho. And I saw a test that the 11 Pro beat out the 12 pro by one hour and some change. So we should all see less battery time then the 11 series.

5watt is the way to keep the health longer

Mine was at 88% with fast charging..

Man!! I had the 11 Pro Max and it was 93% of capacity after 12 months. I did, however, use a combination of fast and slow charging. I also travel a lot and plug my phone into the guidance systems of rental cars...I’m wondering if that is unhealthy for the battery??

For a 2+ year old phone, your battery health is very good - you have treated her well.

You should look at the 12 Pro Max if you travel a lot - the 4G modem has improved and the 5G in some countries are just crazy.

My XS max after 2 yeaes of using fast charging.

The question is, how do you guys charge? Do you let your phone get below 20% then charge till 100%

 

[BigMcGuire]

The question is, how do you guys charge? Do you let your phone get below 20% then charge till 100%

Indeed. My phone rarely sees <70% and I can end the day at 85% (I'm a light user I guess). I can end a year with still 100% capacity - I've been at 96% for 1.7 years.

How hard one is on the battery can definitely vary (if they let the phone run out, if they leave it in the hot sun, if they play heavy games while rapid charging, if they often wireless charge with high heat, etc). 99% of the time I'm plugged in for a little bit with a 5-12w charger. But most of my charging is 85-100% so it's reduced/trickle charging --- which I think in itself is why I tend to do so well in the battery health arena.

Ya I’m a heavy user and always went below 10% daily. I am going to go back to slow charging (5watt) and not let it get below 20% anymore. Maybe setup a automation so low power mode comes on after 30%

Tom’s guide tested the iPhone 12 Pro and found it lasted (11:24 on LTE) vs. the iPhone 11 (11:16). The iPhone 11 Pro when tested by Tom’s guide lasted 10:23. Different reviewers are going have different results which will be the case for each user depending on how they use their phone.

Switching 5G off and retesting, each phone lasted nearly 2 hours longer — the iPhone 12 turned in a time of 10:23 over LTE while the iPhone 12 Pro lasted an impressive 11:24.

I am not clear why this is an issue. Charge Overnight and then who cares how fast. I have never needed a fast charge. Is an excuse to get more money from you.

So you guys prefer to use classic 5W charger over 20W???

 

[BigMcGuire]

For the 11 Pro Max and 12 Pro Max - I don't recommend it. The 5w brick gets way too hot. (at least for me).

For the 11 Pro and 12 Pro - sure. It's ok but it charges really slowly.

I prefer the 18w or the old iPad 12w chargers for the 11 Pro Max and 12 Pro Max. If you have any old 5w 2.4a charger (Anker,etc), those work well too and aren't terribly slow.

Yes they will come up with different results. And none of them had 5G going. If they did every 12 would lose to the 11. Which 5G and camera is the biggest selling point of the 12 series. So testing a 12 without 5G on is pointless in my opinion. Why should we have to turn off a major upgrade to save battery. The battery should be big enough to handle the upgrade and still match last years.

 

[staggerlee41]

My 8+ has 92% capacity on the original battery. I've used Anker Power Ports, Anker PowerWave 7.5 Wireless Charger or the Anker 40w 4 port charger and standard issue 5w charger. No issues for me.

Do you prefer MagSafe?

 

[Sam in SoCal]

Do you prefer MagSafe?

I know you directed this question for another person but Anyways I returned my MagSafe charger for a simple reason. With the silicone case on it generated significant heat to the phone. Not as much with the case off but imagine having to take your case off and on all the time just to charge the phone. To be fair I returned it the same time I picked up my max so I didn’t have a chance to try it with the leather case. Any charger That generates too much heat to the phone is a no go for me. Corded or wireless.
