FAQs on Galaxy S6 Fast charging

Q1: Can I disable Galaxy S6 fast charging on Galaxy S6 or S6 edge?

A1: No, you cannot disable Galaxy S6 fast charging in the phone settings. This is different from the fast charging in Galaxy Note 4.

However, Galaxy S6 fast charging will be disabled automatically when:

• you are not using a normal wall charger, not the adaptive charger.
• or you are using the phone with screen on.
• or battery level is more than 50%.

Q2: Is Galaxy S6 fast charging harmful for the battery?

A2: No, Galaxy S6 fast charging is not harmful to the battery in Galaxy S6. Otherwise, Samsung would not bundle the phone with an adaptive charger.

Galaxy S6 fast charging may only marginally affect battery life. Such impact is negligible compared to battery life span.

For most Galaxy S6 owners, after 18-24 months, the battery will lose about 25%-50% capacity. This applies to most quality smartphone batteries, not just to Galaxy S6. Most smartphone batteries have a shell life of 2.5-5 years only.

So, after 18-24 months, if you want the battery to perform as today, you need change the battery, no matter you are using fast charging or slow charging.

Q3: How long should it take to charge my Galaxy S6 when fast charging is used?

It should take less than 2 hours (around 1.5 hours or even less) to fully charge the Galaxy S6 or S6 edge with the bundled fast charger.

The charging time depends on several factors: battery usage by the background jobs on the phone, power supply stability, battery level left before charging, and ambient temperature.

Q4: Galaxy S6 got hot when fast charging is used. Is it normal? Should I be worried?

It is normal to feel the Galaxy S6 is hot when it is being charged.You probably should not be worried about it.

Galaxy S6 has its own protection mechanism to prevent overheating. It can automatically adjust the charging current based on temperature feedback.

Q5: Should I use slow charger for Galaxy S6 to extend the battery life?

Unlikely, a slow charger can noticeably extend battery life for your Galaxy S6 or S6 edge.

You probably are wasting time and investment for not using Galaxy S6 when you need. The value of the phone is reflected how many hours you are using them.

Again, you still have to consider to change the battery after 18-24 months if you want to continue to use Galaxy S6 then.

Q6: I need a new wall charger, how can I know the charger is compatible with Galaxy S6 (or S6 edge)?

You need read the specs of the charger carefully whether fast charging is supported.

The best option is to get a Samsung Adaptive Fast Charger.  You can normally get it under $20, although the MSRP is about $35.

Q7: Can I use my Galaxy Note 4 fast charger for Galaxy S6?

Yes, you can use Galaxy Note 4 fast charger for Galaxy S6. They are compatible.

Q8: When connecting fast charger to wireless charger, Galaxy S6 fast charging is not working. Why?

It should NOT work. Wireless charging is not compatible with Galaxy S6 fast charging.

If you need fast charging, you need connect the charger to the phone directly.

For wireless charging, the adaptive fast charger works just like normal wall charger.

Q9:  A guru told me I must connect the fast charger to wall outlet directly, not to an extension cord,  to get Galaxy S6 fast charging. Is it right?

No, it is totally wrong.

The fast charger has no way to know whether it is connected to the wall outlet or an extension cord. And this is NOT important.

On the contrary, if you have a surge protector, it is better to put the charger behind the protector (and usually connected to an extension cord).
