Hi i would like to understand if the fast wireless charge ruins the battery. The wired fast charge use a 9V charge and it ruins the life of the battery. Does the wireless fast charge also works at 9V or it uses the 9V only to have enought watt of power to charge wireless at 5V and closest Ampere of the wall wired charger ?
I heard over time the fast charging kills the battery cells. I hardly use the feature. The article suggest to avoid ultra fast charging

Yes this is normal i know that but i did not understand if the FAST wireless charger is at 9V 1.5A or 5V 2A the first one is the charge that ruin the battery

So I just bought a car usb charger, which is rated at 1.2A on one port and 2.1A on "Fast charge" port. I think the 1.2A should be safe atleast, but whatabout the 2.1A one?

As it says, it's for fast charging. If voltage is correct, there is no problem. Maybe a warm battery during charge time.
I'm looking for advice on the quickest way to charge my phone.
With the stock (1.5MA) charger and cable I get about 1200mA current of charge
With a Mr Phone 2A charger it maxes at 1000mA charge current
With a friend's Galaxy Tab 2A charger it maxes at 1600mA charge current.
(Figures above were obtained using Battery Monitor Widget app)
So firstly I'm confused as to why the higher rated 2A Mr Phone charges less than the stock 1.5mA charger when the Galaxy Tab charger, with the same specs, is much quicker.
Secondly, what is the maximum current the M8 can charge at?
Thirdly, what have guys found to be the quickest way to charge? I was going to source a Tab charger as that seems to be very quick or order this Anker desktop charger: http://www.amazon.co.uk/Family-Sized-Desktop-Technology-External-Batteries/dp/B00EJA28ES
Check here at "Charge Time" and/or here.
The stock mains is Quick Charge 1.5, so the phone would charge faster than a 2A "non-Quick Charge" mains. If you need a faster charger, get a Quick Charge 2.0 compliant charger.
Edit: Don't think Quick Charge 2.0 mains are available yet. Have to wait for their release.

Quick Charge 1 is not part of a chargers spec. Only QC2 is.
There's no such thing as chargers that are quick charge 1 or 1.5
And that doesn't explain why a 2A Galaxy Tab charger is quicker than another 2A charger

Hello!
i've noticed that my p9 came with a huawei recharger with 2000mA, so it is supposed to recharge fast.
But it does not. It recharges with an average amps of 600-700.
So i was wondering, maybe it depends on the cable?
Is it enough to buy a new usb-type-C cable usb 3.0 with 2400mA support?
The charger in the box is not a fast charger but a regular 2A and 5V able to fully charge your phone in about 2h20m. For fast charging you need 9V. Refer to this topic for more details. http://forum.xda-developers.com/p9/help/charger-huawei-p9-t3373037
oh, i see. i wasnt thinking about voltage. i thought it was only a mA matter.
thank you!!!
Hi,
I have a funny setup: solar charger/table decoration connected to a wireless charger (stuff from ebay with Samsung logo).
So I assume it will charge so slow if any at all. But still.. at least won't discharge during office hours.
Would this hurt battery in any way?
Well it should not hurt it. If most, like all wireless chargers they are actually good for your battery health. Wireless charging charges slow but does not strain the battery as much. If you fast charge your phone it does worse to the battery long term
However if you post the model of your charger we can look it up and be sure
will slow wireless charging hurt my batter if I'm using a Samsung wireless charger?
model: EP-PG950 - 2018 model that i received with my note 8
Same Question
I had the same questions. I also see there is an option for fast wireless charging in settings. If slow charging is better for battery health and you mostly leave your phone charging over night, would it be best to leave fast charging off so it takes most of the time you are sleeping to charge slowly until full?
At the moment I leave my phone at low charge while I sleep and wake up 2 or 3 hours earlier to plug it in so that I don't over charge the battery.
Wireless charging creates more heat so this question is hard to answer as I have not seen any good breakdowns of qi vs fast. I have been wirelessly charging from older chargers like the wireless charger that came out for note 4 and some 3 coil charger from Nokia that was on clearance for $15. They're not fast wireless charging and phone does get warm. I also charge off of 500ma and 1A chargers usually and only use the adaptive fast charging (QC2.0) when I need a quick top up. Heat doesn't help your battery.
Perhaps somebody can do a comparison with regular qi, fast qi, 1A or less charger and the adaptive fast charger and see what the min and Max of battery temp is through out charging cycle. I'm guessing 1A charger is the best and regular qi is ok. Fast wireless and Fast charging get your battery temp higher.
I got this problem recently, my battery says its maxium is 4.35V, but when i try to charge it with 5V charger it doesnt charge,
What i do?
Depends how many amp battery it is bud
Thank you,
