First charge

Mine arrives tomorrow and I really don't want to leave the battery charging for 12 hours before I start playing with it. The quick start guide says that it'll be fully charged after 3 hours - will I degrade the battery if I only charge it for 3 hours the first time?

it is reccomended but not manditory. i'd suggest use it out the box as is just make sure that your initial charge is for 12 hrs. mine came almost fully charged so i was able to have a good play when i got it. when i did charge for the 1st time it was for 12 hrs.

Usually you're supposed to use a device until it's dead or close to it before charging it the first time.

The long duration charge is old recommandation for NI-MH batteries. For the New Li-ion when your phone stops charging, it'is finished because the phone cuts automatically the charge. You can unplug the phone and use it...
If you read scientific articles about battery technologies you will find the following:
- Li-ion is instable charging technology that why inside the battery there is a charge controler
- Never discharge completely the battery. If the internal control circuit is not powered the charge after will destroy the battery. That why generaly your phone power off arround 5 and 10% of charge.
- Half charge is considered as half cycle: if the battery has 1000 cycles = 2000 x 1/2 charge.
- Best storage condition: Half charge after full charge and half discharge. Battery storage doesn't like hot conditions. Fresh and not wet conditions.
My Wizard has more than 4 years and I uses the original battery... the battery life is perfect...
Ps: I have a Sony NW-A808, I changed the battery because the player did not keep the charger (3 day after the full charge It was empty). With the new battery it's the same... I discovered an Hardware/Firmware problem...

Galaxy note 2 charging help

Just unboxed note 2 ..
I wana know how much time it takes to full charge from zero?
And this is my first use ..how much should I charge?

In the mains about 2-3 hours. Double that via usb. But it lasts a hell of a long time in fairness.

Should I charge for 6 to 8 hours

Ah that's a coincidence.
A few days ago I measured the time it took per minute to charge with the included adapter (which is 2A); it charges 0,93% p/minute. So it takes 107,5 minutes to full charge.
With a 1A adapter it charges 0,54% p/minute (185,2 minutes for a full charge).

Modern li-ion batteries dont need that long first charge.. it was only needed with nimh batteries.
but it wont hurt. i allways make the first 3 charges long and allways try to get down the battery to 20% before i charge.
better to be safe then sorry

Battery of my Note 2 take 3 to 4 hours to charge dont know how you guys manage it in 107 minutes! Tested the charger to be sure but i think its allright.
The battery is fine too, it lasts 8 hours of use without charging. and 4 to 5 hours of use time and 20 hours standby (24 hours total) with light use i get round 3 hours screen on time and 48 hours standby.
But charging it in 1.5 hours.... no way! It takes more then 8 hours to charge in an USB port

Normal charger takes 4 to 6 hours to charge. even when Phone is off. i tried using another 2Amp wall charger and replaced the battery. also reseted to factory default.
All with no luck. I dont know whats wrong bu i think its in the software. because when charged allot on USB or short charges when only 10% charging. the software/battery seems to fail to give the right amount of power. and the calibration is off. Sometimes when i have 20% left and reboot the Phone it all of a sudden has 30% or more.
Since the latest update this has become worse and worse.
The battery is easily lasting 24 hours with 4 to 6 hours screen on time. so i think there is no power draining going on.
I really think its an error in the note 2 software. i read allot about people having the same issue and need to charge their Phone for hours only to see its charged 50%.

2 questions about battery?

Hi, I recently bought a Lenovo P2, and so far it seems to me to be a great device.
The battery is great and I usually go to sleep with a 65-70% of charge.
So I have a doubt: Should I charge the phone every night, even if the battery is half charged, or should I wait the battery to reach 25-30% and then charge it?
Also, Does the fast charge ruin the battery if often used?
Thanks

Wait for 25 to 30 percent and charge till 80 to 85 percent. It'll make your phone battery last really long!!!!

Why not till 100%?

Because these batteries are at their best between 20 and 80%. They don't like being run right down and charging them to 100% increases the wear on them.
So they will last longer by keeping them between 20 and 80%.

So, those tricks I've read, about discharging till 15% and charging to 100% to calibrate battery, are useless?

You read it wrong. To recalibrate the battery you must fully discharge ie. to 0% till the phone shuts down by itself, not to 15%. You can fully discharge once per month. To prolong the battery life span try to charge from 20 to 80%. I know charging up to 100% is nice, but all experts tell us that it's not good for the battery in a long run.
Even partially charging from 20 to 80% you still have ~8-10h SOT so all is fine, 2-3 days on a battery are possible.

Is your phone quick charging ?

I used a few Qualcomm Quick Charging phones before, quick charge 2.0/3.0 and they were all pretty quick to charge, like 30 mins 60%. Just before the Razer I had the Oneplus 3T which used the Dash charge technology and that was like superquick.
The razer supposedly has the latest QuickCharge 4+ technology.. but I am yet to see the phone charge "QUICK".
When connected with the original razer wall charger, It is maxing at about 1920Ma using 4.01 V. (checked using ampere app)
I also tried a different usb c cable, on a different quickcharge 3.0 wall charger and it is giving me exatly the same output at 1920Ma max.
This is not right, is anyone else experiencing similar charge speeds ?

Don't know the electrical figures but performance wise mine charges to 60% in the first 40-45mins.
But then sadly it takes a while to finish the full charge. Like another hour.
On the lockscreen it states 'rapidly charging' so it seems to be using the technology. Remember this has a 4000mah battery, what phone were you using before?
That being said I'm getting fantastic battery life so in my case this doesn't bother me.

Good batt life here too. About an hour and 50 minutes from 4% to 100%.
Not sure how right that is. I think it was prolly 30 to 40 minutes to 50% or so.
Funny thing was, I charged while the phone was off, the white icon on the black background showed 100% (no numbers but it was full) but when I started the phone the battery status was 95%.

Ok, I got the other phone replaced because it had couple issues. I put this new phone on charge last night when it was on 7%. On the ampere app it maxed out to like 3000 something Ma and there was a buzzing/whining noise coming from the charger/wall adapter. I left it on charge till like 40% or something and I was not comfortable with the sound from the charger so i removed it.
Put the phone on charge today, it was on 35%. The sound from the charger is still there but not as loud as yesterday. Checked on the ampere app, its pushing on average 1900Ma this time.
35% at 11:27
50% at 11:45
61% at 11:57
75% at 12:13
91% at 12:34
96% at 12:48
1. I still feel the phone is not charging fast enough although it is saying rapid charging. Like mentioned before, connecting the phone to a lower standard quick charge 3.0/2.0 power port is charging at the same numbers..
2. Having looking at these links below, the numbers dont add up to what they are advertising quickcharge 4+ with.
https://www.qualcomm.com/products/features/quick-charge
and https://www.qualcomm.com/news/onq/2...alcomm-quick-charge-4-your-next-mobile-device
3. I've never had any charger/ wall adapter that made such noise. Is this a defective unit, or is such noise on these expected if it is like charging at a faster rate? the previous one was queit.. but then again the previous one did not push over 1900Ma, this one got to over 3000Ma.

Don't know what to tell ya, but I've heard zero noise from the chargers, I've got 2 units. Purposely kept my original instead of using the rma'd charger just in case. I'm not sure what their total sales are vs defective units, would be nice to get some communications from razer though.
I'm glad they got an update out after 5 days, shows they're working on it, but the update broke the sound and there's questions people have, all razer seems to do is say 'contact customer service'. Which isn't very cool when you're sitting there wondering wth is happening with the direction of it all.
Still love the phone though. Best specs of anything out there, sounds like just as many bugs as the pixel 2 or the iphone x too. heh
And it's a bonus to razer since this is their first and those companies have been doing it awhile.

I was on live chat yesterday, they said they will go through with the warranty team and try send me a new charger. They will probably just send out the same thing. The dash charge cable my oneplus 3t had was proper thick and that was charging at around 3000-4000mA on average till like 60%, then it would usually slow it down but that was a proper quick charge.
I connect this cable, it pushes to 3000mA for like 5 seconds and then goes back down to 1900mA. I think its either that the equipment they are using is just crap and not ready for quick charge or that they have large number of defective charging units.

Sad to be bumping this but I also have huge amount of noise coming from the charger, I have to say that 60% on standard phones is half or less of what 60% on the razer is, but yeah there is no difference for me from QuickCharge 3 and 4+, it's quite weird.
I'm going to go through and get a new charger, also the cable's lining is also ruined somehow, detached from one of the USB-C ends and as far as I can see seems to be protruding some alloy, most likely just some protection but it's really just what usually happens, also with mices from Razer.
Goodluck to everyone.

I'm using both the included one and my old nexus 6p one and both charge rapidly and pretty freaking fast too

I've come to a conclusion and still awaiting feedback from Razer aswell to confirm this, that either my phone is defective or Razer are claiming to have this phone equipped with QC 4+ but it really is not.
Qualcomm say:
When Quick Charge 4 was announced, it promised to bring even faster charging than its predecessor, allowing a device to go from empty to 50 percent in just 15 minutes.
The current Quick Charge 4 technology, announced in November of last year, promises five hours of charge in five minutes, a 20 percent improvement in charging speed and 30 percent improvement in efficiency than the previous Quick Charge system.
The company announced even more improved specs today: the Quick Charge 4+ system, which the company promises is up to three degrees cooler, up to 15 percent faster and 30 percent more efficient than Quick Charge 4.
So can anyone confirm that you are getting these numbers when charging your phone? No way near what Im getting. I've tested and compared the charge speed using Ampere App and could not see a single difference between QC 3.0 and 4+ on this phone. I've used the original wall adapter + usb c cable combinations as well as using a standard QC 3.0 wall adapter and a usb 3.1/3.0 cable.
The phone starts charging at around 3800mA upto 25% then reduces drastically to 1800mA and charges to full charge. Issue lies here because at 1800mA the phone is NOT quick charging. It charges quick upto 25%, very quick actually but after 25% it charges very slow. I know the fact that due to heat the phone will not charge at 3800mA throughout so would need to drop but this drop should not be at 25%. My oneplus 3T used to charge at around 3000-4000mA 60-70% then used to drop towards 1500mA-2500mA mark and would complete the charge at this rate. It was very quick, 0-70% was like in 30 minutes.
This is what I've got yesterday.

14:57 / 21% / 42 mins untill full
15:01 / 26% / 44 mins untill full

Took 108 minutes for full charge from 15%. This cant be right for sure? Can anyone confirm.
Note: I've had no apps running or anything in the background. Also note at 14:57 it said 42 minutes for full charge, 30 minutes later it was still saying 42 minutes for full charge

I think I'm going through the same thing. I'll charge and test it.

My experiences are similar to others. I am not using the box charger. I am using 2 types: Motorola TurboPower 30 USB-C, and the AUKEY 70W Charging station (Using the QC 3.0 port). I have no idea if its doing QC4+.. It just says "charging rapidly". I am using an app called AccuBattery pro. It is at 85%. See the attached picture for the metrics charging on the Motorola charger. The one thing I miss, which my Nexus 6 did without an app, it would tell me how much time until full.

I have the same exact issue

Can you guys all test your charge using the Ampere app and jot down the numbers like I have done. Make sure you put it on charge when the battery is below 25%. If everyone is getting the same numbers then the phone does not come with QC 4.0+ and/or it cannot handle heat properly hence it is only charging quick upto 25%. Or else, some of us have bad units.

I'm experiencing the same behavior you are using the QC4+ Charger and cable that came with it.

I did get in touch with Razer and at first they were not willing to accept that there is a problem and they were insisting that the behaviour was normal. After forcing them to "explain" why it was normal, they could not really say anything so they gave up on it and now they are saying I could send the device in for them to check it. I also got the half screen freezing issue which I believe is a hardware problem (somewhere on this forum and Razer forum confirmed) so I have just put a RMA request and will be testing out the replacement device when I get it. If the replacement phone is no different and all you guys are getting the same numbers then like I said, I dont think Quick Charge 4+ is implemented to their devices and its just "false advertising". I cant think of anything else.

Had the same issue charging stops at 20%
but the problem is not constantly appearing

Well so far we have yet to see someone come and say Quick Charge on their phone works after 25%.

Bit of a misunderstanding
So first of all Qualcomm states up to 50% battery in 15 minutes, but that will only hold true if used on the smallest of smartphone batteries aka round or just bellow 2000mah.
So technically 1000mah in the first 15 mins which will be about %25 of the razer's 4000mah battery.
Razer is selling the chargers themselves on Amazon on the razer store and in the description they quote up to %50 battery in 40 minutes which in real life means 50 percent in ideal lab situations.
So your phone and charger are working correctly and at the maximum nowadays technology allows.
Just always remember with anything new that comes out with technology like when they touted the up to 4g speeds theoretical limit this and that etc hardly anyone if ever anyone will ever have the pleasure of experiencing the up to... that has been touted.
I hoped this helped and maybe clarified things for some people.

There is nothing to misunderstand here. The last phone I used had a 3400mAh battery and charged to 60% in 30 minutes. Razer has the extra 600mAh yes, maybe the charge technologies are not exactly the same yes agree on that too, but this does not mean that the 4000mAh Razer could only handle Quick Charge upto 25%. Whats the point of having the technology if the remaining 75% is going to be slow. Doesnt make any sense, Quick Charge 3.0 devices dont work like this so why should it be this way on this phone.
Took 108 minutes for full charge from when the phone was on 15%. Said 42 minutes for full charge. 30 minutes later it was still saying 42 minutes for full charge.
Im just not convinced that Quick Charge 4+ is working as it should on this phone. Either software or hardware related dont know but something is wrong. On this forum or the Razer forum cant exactly remember but some guys were saying how the provided usb c cable was not even a proper usb c cable and it was too thin. Just thinking maybe that might also be a reason or maybe not i dont know.

For a 3400 mah battery to charge to 60% in 30mins you would need more than 7amp charger .
I don't even know one if they exist.

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
Regards.

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.
Best regards.

Hi Sufyan3D,
Thanks a lot for that info...
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...
Regards.

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?

Will need to measure that the next time I charge it as it's now at 100%! How long does yours take from 15 to 80%?

I've never tested it. I have fast charge turned off. I charge my phone over night. The battery lasts me all day every day.

Samsung A70 Failed!!
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?
