Should I be paranoid?

[legend8887]

I always charge my iPhone 6S Plus with my portable battery charger than outputs 2.1 amps even though the charger came with it is only 1 amp. It charges it faster but should I be afraid of damaging the battery overtime?

It's fine. It will only draw as much amperage as it needs. If you had a 5V regulator and a car battery you could charge a phone.

LIPO batteries are rated in C. i dont know what rating a iphone has but usually overcharging or "quick charging" will damage batteries over time and cause the MAH rating to drop down.

does it have a builtin potmeter or voltage reg?. then it wouldn't charge faster with a 2.1amp charger vs a 1 amp ?

The amount of time it takes for this to have any effect is longer than the typical 2-3 year phone ownership period.

Apple has it's own fast charge standard but not sure why the standard charger is only 1amp.  Chargers don't force power into phones, it only sends what the phone requests.

Again, the phone will only draw as much current as it needs.

I was just making a point.

You're paranoid, You're tripping. Been smoking? Been sippin'

As long as the voltage stays the same and the amperage is equal to or greater than the original charger, you shouldn't have anything to worry about

Also the 6s has intelligent charging, so it disconnects the battery internally to prevent overcharging when the battery is ~100%, and reconnects it ~90%-95%.

People always say this, and yet I've never had a phone battery that wasn't noticeably weaker after a year.

I usually charge my phone overnight with a 500 mA (standard USB rate) charger. I'll top it during the day if I have to with the 2.1 Amp that came with it if I need a quick shot to make it through the day.

And when did this old phone start losing its charge? What year? Cos QuickCharge was only introduced in 2013, and there's no such thing as overcharging.  Hasn't been a thing for years.

I don't think my post implied "old phone", or dates, and I certainly didn't say anything about overcharging.

Every phone I've had has experienced battery degradation, this goes from the original Moto Razr flip phone (I miss that thing) up to my current Galaxy S5.

The GS5 and iPhone 6 Plus have roughly the same rated charging time, around 2-2.52.5 hours depending on who you believe (via Google so sorry if I'm off by a bit). The S5 has a 2800 mAh battery, the 6+ 2915 mAh. Since the batteries are roughly the same size and charge in roughly the same amount if time, it isn't unreasonable to conclude that battery wear will be similar.

I'll also mention that technically neither phone (barring the Japan GS5 variant) actually has "Quick Charge" which is a Qualcomm technology. Both however do charge in what is considered a "high speed" rate.

As for overcharging, not only is that "no longer a thing" but it has NEVER been a thing on any device with lithium based battery technology. How can I guarantee that? Lithium batteries have a nasty habit of bursting when you overcharge them, and I don't recall a phone that popped if you left it on the charger. Overcharging batteries was a problem people had with cheap chargers (because the good ones would shut off) in the NiCad days, because they were a simple constant voltage charger that never turned off.

Obviously companies have enabled various high speed charging technologies on their products, and a charger can't force power into a device faster than the device is allowed to receive it. These companies have made the decision that the value add of having the feature is unlikely to cause reported problems within their "device lifetime" (warranty period) or else they wouldn't do it.

So yes, the manufacturers say faster charging is safe. I think they're biased because to them, a device only has to last a year. In my experience, things last better when charged slower. As with all things, YMMV.

(Bring on Huawei's graphite anode 3000 mAh battery that hits 48% in 5 minutes, supposedly degradation free)

This is something that happens with virtually all rechargeable batteries. Battery degradation is not exclusive to phones.
