On Quick Charge, it's fast. On a older computer, it's painfully slow. In my car, on a standard charger, it's not too bad. I just bought a QC 3.0 charger for my car and it'll charge about 30% in my 35 minute drive home (have to test that some more).

I would double check the charger port and make sure your plugging into the QC 3.0 port, and not the 2.0A port (not sure if yours has one as well or not) my Axon 7 charges about 45-50% in my 25 minutes ride home so It doesnt sound like its charging quite as fast, unless its QC2.0

Have tried to push the battery as hard as I can while charging at the same time. The phone won't stall or drop charge thankfully. Gets a little hot but nothing like other phones I've owned (Nexus 6P would boil, OnePlus one would slowly drop battery until it died, iPhone 5s would get too hot to touch, HTC M7 would also become too hot to touch and unresponsive). If you're wondering if you can use this phone with GPS, Bluetooth, Wifi Hotspot, Data, Spotify while charging at the same time you can.

B27 A2017U, From 37% to 95% in 45 minutes. 5 minutes of screen and one 5 min call during charging. I won't use fast charge often because I don't need it, battery health is more important to me.

Charging speed is very fast. Battery life is great. I usually have ~20% left after running it from about 6AM to 11PM. I did misconnect the charger dongle one night, and so was at 11% starting the day. I switched to ultra power saving mode and was at 10% at the end of the day!?!

Charging speeds tbh are fairly decent. On QC 3.0 i get about 95% in about 1 hour. Nothing compared to Dash charge on the OP3, that method is insanely fast. To compare OP3's 3000 mah takes about 40~45 minutes to top off. Considering the additional 250maH on the Axon, i think the 1 hour approx charging time is good. I suppose once you get the taste of Dash charging, QC becomes less palatable
P.S. Axon's power saving mechanisms are actually quite good. No need for any 3rd party apps. I don't miss Greenify considering the background apps get killed when the screen goes off. So battery life being decent is a good trade off.

I've been impressed by the charging speed. It's close to the Moto X Pure that I loved.

I've personally never had a phone that had any type of quick charge until this phone, so I'm certainly impressed.

Hello
Question: is QC3 a killer of battery? Is charging at low amp better, or...? Cuz I read here and there that it's still better to use a slow speed charging device so that the battery doesn't heat up and doesn't wear off too fast.
What are your thoughts about that?

If you charge it before you sleep, I would use a charger with a lower am so it can prolong the battery's life. Using quick charge 3.0 is convenient, but it will certainly decrease the battery's life over a period of time.
Before bed: Not recommended to use another adapter to charge any phone that didn't come with it, but I would use a different adapter with a slower charging rate and voltage.
When you're about to go out or etc: Quick charge 3.0

I use the Aukey charger. I have 2 portable QC3 and one "traditional" QC3 also. And I forgot which brand but a good one as a slow speed charger.
I thought that QC3 was different than the "old" high speed charger because it had something to do directly with the SnapDragon. The "old" high speed chargers are just sending more amps like 2A or more, while QC3 is more "controlled" so it didn't affect the battery. Am I totally wrong?

Has anyone noticed their charging time increase by 10-20 minutes or so? Could be my imagination as I also have an op3 now..

Probably your imagination. Dash charge is much faster that QC. If your phone's charging up in an hour it's fine.

Oh yes absolutely. I came from an OP3 to Axon. It's the only thing I miss about the OnePlus 3. And the ROM. And the front finger print scanner. And updates.
On a more serious note, Dash charge is really fantastic. As advertised. 3000 mAh takes 40 to 45 mins, but the most important feature is that it doesn't heat the phone up and using the OP3 while charging is a better experience.

Nice
I think QC3 is already pretty fast, so... Charging low speed when I'm not in a rush, following some (your?) advices here.
I had ordered a 1+3 and canceled when I saw the Axon7, but I had also a Dash Charger on the way and couldn't cancel that one. Too bad they're two different technologies
The 1+3T is... nice

Yeah i absolutely hate the existence of the op3t cause it has everything that op3 didn't. And yeah don't use the dash charger with anything else unless you like watching things getting smoked up.

I don't trust it to keep the battery in good condition over a long time. So I use a normal charger instead.

Best battery life I've ever had!!!

so nice

I must say, while battery life is exceptional, the charge time is not up to part with my S6. I forget what the maH was on the S6, but the S8+ doesn't charge as fast.
Sent from my SM-G955U using Tapatalk

Mine is good

Why doesn't it support Quick Charge 4.0?

Charging speed on my s8+ is very fast. I don't mind that they didn't use fast charge 4.0 or 3.0 or 10.0, that's their choice and all I can do is look at the actual charging speed and not on the technology behind it and in my opinion it is very fast.

Compared to my Moto z force it's nowhere near as good. In half an hour the s8+ would be at around 40 while the z force is at around 60. What do you expect though from a 5amp charger. Just wish Samsung could've integrated the fast charge that the z force has.

its fast charge for the size of the battery

app "Ampere" from PlayStore tells me fast charging feeds it more than 1200mAh consistently
battery lasts more than a day
happy with the Plus

Nothing compares to the Mate 9 and it's Super Charging. 0 to 90 in less than an hour ?

You are right, that's an amazing feat for a piece of hardware
We are behind... a bit with our 8s

Don't depend that app just read the manual and observe your phone.

Can you recommend an alternative?

Yesterday I charged my s8+ with the original fast charger and the original cable and it took 1 hour and 34 mins to charge from 1% to 100% and today I tried charging with the original charger of my s5 and it took 1 hour and 48 mins from 1% to 100%.
This is it? Only about 15 mins difference? 1 hour and 34 mins is quick but the difference between fast charging and regular charging with a normal charger isn't big at all.

AQI7 update had really made things fabulous.
Better standby and faster wireless charging compared to earlier ones.
And QC 3.0 charger charged my S8+ from 12-100 in 1hr 30min

Sammy Finally switched to USB C!! Battery charges considerably faster than the S7 when using an aftermarket 2.4 amp charger.

Will be
SOmetimes it might be the phone of the century

TurboCharge 3.0 is amazing

4 hours? seems a little low, i get easily 3 day with the battery mod, and never had a problem getting to bed with phone still alive, so it last at least 1 day. i have normal usage, social media, couple video calls, online banking, tickets etc...alsa charging is fast for me, i come from a moto g2

The phone heats up a lot while charging with its TurboPower charger, it would be nice a toggle for disabling QuickCharge when not needed.

I never had better phone in my life. Charging is amazing fast, and Moto turbo power mod is awesome. No need to leave phone for charging, leave Moto mod and put on the phone while done. Usually for me it is a matter if I can disconnect charging before phone battery reaches 80%. After over a year battery status shows my phone still has 2850mAh, but all the degradation is taken by Moto mod. Time to change it, but of course... not able to buy it anywhere.

Was great first year when 10w charge was working. Now takes forever and only lasts 4 hours like the guy said. Too bad it uses internal battery.

I just bought a XT170-9.
Battery was 0%, production date exactly 2 years ago.
I think I will return the phone. A lithium battery that has been empty for an unknown period of time is not new any more.
Charging time with 3A 15 W is
30 min - 50%,
60 min - 80%
70 min - 90%
is this normal or too fast for a new battery?

I used USB C PD 18 watts and it's charging rather quickly.
Yes, it supports 18 watts PD charging

50% in 30min is pretty standard, most QC 3.0 takes near that time to reach 50%
I don't know about 80% and 90% either, but I think not having the battery charged for a long time doesn't affect Quick Charge charging time.
But you are right, you should return the phone. I have had bad experiences with batteries being dead 0% for a long time.

Thanks for the answer. I decided to keep the phone. It's a year since I bought the phone and I believe I start to see some drop in capacity now. but apart from that the phone has a very good battery.
Well, low charging times could indicate low capacity...

What kind of charger are you using? Motorola Turbopower 18w?
You know, brand new phones don't have their batteries draining earlier, they at least last like 1-2 years before you notice drop in battery life. If the drop is sudden like from 1 month or 2 them the battery might be the problem, but then since its Moto Z you could try buying those Battery Pack Mods, and they're sort of a strike of luck to get one that actually works the best since regarding Moto Mods people has mixed opinions towards them, because not all of them works flawlessly and some may get faulty mods, which is why there are negative opinions towards them.

Yeah, I got two Moto 18 W charger and one 12 V Anker USB-C charger which delivers similar power.
that's a good idea, to buy a battery mod instead of replacing the battery. will keep that in mind.
At least you could disassemble the mod and replace the battery and won't risk damaging your phone.
only drawback: the mods are super heavy, got the Hasselblad and the Sound Mod.

They need to step it up to 12v 25w at a minimum. It's not terrible as it is, but knowing how much better it could be is a bit of a kick in the shin... especially considering the expense and the fact it's supposed to represent the best of the Galaxy line.
It's good, yet still somehow disappointing.

Considering the competition offers must faster charging, Samsung should let us charge at 25W just like the s10 5G variant will be able to.

It's actually slow as FF. Charging this device (especially with screen on) is a nightmare. During the day, with auto brightness and mostly bright environment hitting ~15-20% in 30 minutes. That's ridiculous.

My moto x pure edition 2015, charges with turbo charge quicker than this s10+ fast charge.

I'm happy with the charging speed, fast enough to charge and not too fast to deplete the battery life!

Same here 1.5hr or less for a 4000+ mhz battery is satisfactory.
The Huawei Mate 20 Pro used to charge from 5% to 100% in 50 minutes, but the overall performance is still far from S10plus. I struggled to get 8+ hours SOT without standby on the Mate 20Pro, whereas with the S10 Plus ive had a steady 9hrs and even achieving 12hrs SOT and 20hrs standby.

I can charge my S10+ running the AT&T firmware here with a LG fast charger in 1 hour 24 minutes coming from 19%

Recently i purchased Samsung 25w charger but its take same time like bundle 15w charger

what's better for the battery, shorter charge/less heat from 50% or 1 1/2 hour full charge from 20%?

what's better or does it make a difference?
1. recharge battery when 50%?
2. recharge battery when 20%?

A70 "Super fast charging" ! Really ?

Hi guys,
For those having the A70, does the "Super Fast Charging" feature work for you ?
With the original provided charger (with the "Super Fast Charging" logo on it), I need 3 hours to go from 9% to 100%.
So that is 1% every 2 minutes...
I do not consider this a "Super fast". I think it is "Decent" but would not go above that...
For me, this a severe disappointment... Unless of course I am doing something wrong
Anyone else can share his results for Super fast charging here ?
Regards.

Your phone must have an error. Mine lasts about 1:20 to charge from about 15% to 100%.

Hi,
Thanks a lot for your answer.
The phone... or the charger maybe ?
Is there something to enable to have that "Super Fast Charging" ?
Or something to not disable ?
If I can solve battery drain (not really lasting as I expect) and this, I will think again about keeping the phone.
So far, it's more a non keeper

Hello . Do you charge it with the screen closed? Only then fast charging works! IF yes then something is wrong with either the cable or the charger .You could also try a factory reset !

Hi,
Thanks for the info => Super Fast Charging only with display off ?
So if I leave "Always On" it will not work ?
Maybe that is why...
Anyways, I did as you suggested : I have done a full factory reset, and I have installed the bare minimum of Apps.
We will see about battery drain an battery charging.
I'll keep you posted.

Hi Sufyan3D,

I've made sure that the fast charge is enabled.
So far, the device is still at 100% so I can't say if the problem is "solved", but I'll make sure to report if now it charges as it should
And also about battery drain...

That's correct! OK check it now and tell us! No battery drain, this thing is a beast! Keep us posted!

Hi,
So far, I cannot tell about the Fast charge.
But the phone is almost idle (really gently used) with "Always on" enabled.
It's been idle since about 3hours and battery is at 98%.
I consider this a rather good result.
Hope it'll stay as it is once I install all my apps...
If not, I'll try to track the culprit for the high battery drain.
Regards.

I have same problem, after reading your post, I drained my battery to 9% and charge, it so slow while charging.

Hi guys,
Well I think it is confirmed that my phone has a problem.
The battery drain is more than acceptable.
I drove my kid to school yesterday. It is a 80 minute trip to go there and come back.
While I drove her, I used the A70 as a GPS whilst it was connected to car audio with Bluetooth.
Battery drain in 80 minutes was a little less than 10% which is quite good I think...
Then I played a bit with the phone and went to bed.
This morning it still had 84% battery.
So that is about 2% battery drain overnight.
Not stellar but acceptable.
So I decided to hook it up.
The battery panel reports "Fast charging plugged in".
But after 40 minutes, I am still at 98% charge.
That means 40 minutes to get 10% battery.
I am aware that the last 10% are the longest, but still... 40 minutes for 10% ?
I will test with another charger to see if it is the phone or the charger...
Regards.

Download a free app called "Ampere" from the Play Store, to measure your charging current. Plug the phone into the charger then open the App to get the measurements. Post your result here and compare with other A70 owners.
App shows that my charging current is around 1100mah (with the 25w charger)

I landed here as I was surprised how slow my A70 was to charge. It takes around 3 hours to get from 15% to full, using the included Samsung 3A charger & original cable. Ampere shows the current trickling in at around 850mA. Super Fast Charging is enabled. My previous phone was a Xiaomi Mi 8 Lite which charged at around 2A according to Ampere.
PS I found this link which suggests most of the fast charging happens early in the cycle https://www.sammobile.com/2019/05/02/how-fast-is-samsung-25w-super-fast-charging

The Charger is rated at max 2.77 amps and 9 volts for fast charging. It will vary through the charging cycle though. Towards the end, above 80%, the charging will slow. How long does it take from 15% to 80% and what is the measurement in the middle of that?

I think A70 is failed in all fields.
No porper GCam. And now batteries.
My device getting charged in around 4 hours with original cable and charger.
Now I think I invest 27k in wrong item. OnePlus 7 or realme 3 pro was far better than A70.
It's just name Samsung, nothing else. Blank box with tag of Samsung. Really disappointing with this.
Sorry to fans of Samsung devices. But I don't like this. After 2011 (Samsung Galaxy Y s5360), I think Samsung is better nowadays but I was wrong. I will never buy Samsung phone again.

I am not facing such issues in my device. Regarding development, for a device like a70, development is always slow. We have the source codes available. The only thing missing is developers onboarding to support the device. If at least 1 dev puts the kernel and device source codes and tree in github, I bet development will start soon after.

I took some readings with Ampere during a charge:
0 mins 8% battery 4050mA
30 mins 38% battery 1060mA
60 mins 52% battery 1050mA
90 mins 66% battery 1020mA
120 mins 81% battery 1080mA
150 mins 91% battery 1000mA
180 mins 100% battery
So 3h from nearly empty to full which is not exactly fast. Is this in line with what others get?
