Minimum power supply - Google Pixel 2 XL Questions & Answers

Hello guys. I know nothing about electronics and I don't know if this will make sense or not, but I'm wondering if anyone knows the minimum power required to charge the xl 2 and use it at the same time.
The reason I ask is because I want to get an external battery to charge my phone in case of emergency, but ideally I'd like to be able to use it while it's charging. So how much power does the battery needs to output to "beat" the phone's average power consumption?

You need a Power Delivery capable power bank. All PD power banks deliver at a minimum 5V/3A and 9V/2A (or higher) and will charge your phone "rapidly". You need the rapid charge to overcome mapping/navigation/music streaming and still maintain a net positive charge. Note: I recommend specifying one with a USB-C INPUT & OUTPUT so that you can re-charge the power bank rapidly. There are some cheaper ones out there with PD OUTPUT but will not accept charging through the USB-C port, thus the re-charging time is much longer. :good:

Compatibility with Nokia fast microUSB chargers

The Samsung charger adapter which comes in the box is very slow in nature. It take more than 2 hours to charge my phone. I was wondering if I can use the following Nokia brand chargers which are fast chargers?
Nokia Charger Adapter CA-146C
Nokia Fast Micro-USB Charger AC-10
It won't make any difference the phone decides what current it draws from the charger, so it'll take just as long to charge.
Are you really sure about this? Can you link me to some articles which confirm this.
Even I was thinking about purchasing AC-10 charger from Nokia.
How fast is the nokia charger?
0-10% -> 100% in an hour or less?

I'm not sure about this. I have a friend with a Blackberry Playbook and he reckons his phone charges much faster if he uses the charger from that.
The "stock" S2 charger is 700mA - it doesn't take a genius to work out that for a 1650mAh battery this will take about 2.5 hours to fully charge the battery under ideal conditions (phone off) or anything from 3-6 hours with the phone on, depending all what's running or if you're using the phone while it's charging.
Which is all pretty ridiculous - ok we're comparing apples and oranges when we compare a S2 to the likesw of a Nokia, but I do miss the days when I could charge my phone in an hour and have it last two or three days. I thought my Blackberry was bad but at least I can usually squeeze a full day out of it...
The only wall wart I had lying around that was more than 700mA was a 5V 2A supply. I've tried with that which works, but the phone chokes with a "battery overtemp" warning after about 10 minutes - which tells me I AM pumping more into the battery than it can handle. This would suggest that there IS a happy medium where we can optimize the battery charge time - I'm bust looking for a 1A supply...
I have TWO AC-10Xs, and am using it with the Ninphetamene kernel (which comes with increased charge input mods to 800ma) fine. Charges to full in about 2.5-3 hours.
I've never gotten overcharge errors either.
Hi,the usage of more powerful charger will eventually reduce lifespan of your battery. This comes from basic physics, materials and so... Higher mA means faster current, which wear the material of the capacitor - battery.
I have capdase 2 USB car charger that was used for my old iphone device.
It outputs 1A.
is it safe to use it?
I tried to charge with it for 10-15minutes or so, and didnt recognize any suspicious warmups...it reached 41~degrees while at the moment im charging and using it as a hotspot and its on 38 degrees.

The phone (specifically, the kernel) limits charge coming in, and there MUST be hardware limiters on the batteries and the phone themselves (which, in some cheapo batteries DON'T WORK and results in them frying themselves and the phone in process) and the batteries are replaceable anyway.

i use htc wall charger rated at 1A and having no proplem with ,a pc USB port is capable of 1A and we all know there are no problem ,even so there are no visible improvement in charging time because as someone said the charging current is automatically regulated

That's good to know that the current is regulated by the device.
Is there a software to see what is the current taken by the phone?
As long ad the temperture isn't higher than 45degrees is it ok?
By the way, Im pretty sure that usb outputs 0.5A and not 1A

battery monitor widget
It seems logical to be able to use all chargers as smartphones all have micro usb .
(I 'm not sute that's mean something in english, sorry)
Great widget! thanks.
I really like the data it gives!
Sadly, while charging with my .7A original charger & meanwhile giving a hotspot to my laptop, it shows that only 76mA comes in!
hehe, gonna take forever to charge the battery this way.
i doubt this. i'm still worried about the compatible problem~~~
After two days with the battery monitor widget Im affraid itself it drains the battery.
could it be it affects the battery?
settings are regular, it monitors changes every 60seconds
Let's see if I can help make things a bit clearer. Feel free to correct where I may be off.
The Nokia thing, it's not a charger. It's a power supply.
The "charger" is built into your phone, hardware-wise.
How can I prove it?
Take the Samsung supplied cable, plug it into your computer. You'll see that your phone is charging too. No, the cable is not a charger. Do you think your computer is a special built charger for your phone? Hardly.
The charging circuit is within the phone, and thus charging the battery when there's available power.
Ok, so we have the charger (i.e. the mobile phone), we have the battery, we need the power. Where do we get power from? The wall adapters (or computers). So what are the wall adapters? Ratings of 1000mah means that the wall adapter can provide up to 1000ma per hour.
However, your charging circuit will determine how much current to actually draw. For example, drawing 800mah for 10 min may raise the temperature to 55 degrees, so after 10 min the charging circuit drops the charging current to 500mah.
Of course, if you're using el cheapo cables, some cables may not be able to support the current draw and you may find that even with 20000000mah power supplies your phone can only draw 100mah.
The SGS2 heats up pretty easily, and it doesn't quite draw beyond 700mah. The circuit built into the phone doesn't allow it to, if i'm not wrong. If your phone is overheating while charging, you better change your case as it's going to cause your phone to overheat sooner or later.
Using a 20000000mah power supply isn't an issue, because the charging circuit within the phone will be able to draw only a certain amount.
Me, I plug my SGS2 into a 2Ah charger every night to charge, and yes it's perfectly fine. I'm only upset that after buying an expensive 2A charger, I realised that the phone is not able to draw high currents (phone even heats up to 55degree Celsius when charging).
Charging the phone on a ice pack (which lowered the phone temperature to 16 degrees while charging) didn't increase the amount of current drawn by the phone, even on a 2A power supply.
My humble advise is, stick with the stock power supply, or at most get a 1A version. No need to splash for a 2A power supply. If you really need faster charging, get a battery charging dock.

yes of course it does. It consumes a certain amount of ma per hour, doesn't it?
Personally, there's a app called watchdog, look for it, IMHO it helps to catch rouge apps better, and manage battery better.
I thought the whole idea of having a universal micro USB charging connection across most good brands was so you could use other chargers!

[Q] [ION and possibly others] Phone loosing charge while charging via car charger

Hi,
I use my Xperia Ion (running rooted stock JB) as a navigation and dashcam unit. So naturally I want it plugged in while I have it in my car. However I have noticed a slight "bug". The way I understand how the charging works is that the phone will charge at full power (1-1.2A) until a certain point (% of battery) and then go into trickle charge mode (300 to 600mA). When using my phone the following function are in use:
Bluetooth
LCD
GPS
Camera
Wi-Fi/mobile data
Phone
This will all need power. And while the phone does seem to charge in the car if the battery is low (>50%), it will stop at 70ish %. Depending on the charger I use it will stay at 70% or start draining again. With some chargers the phone only drains power and will never charge unless I keep power use to a minimum. I.e. not use it.
I have tried many power sources. These include:
Motorola dual port charger (for Motorola Atrix car dock)
Quality brand universal USB charger
Sony Xperia charger
Laboratory power supply with different configurations on the USB data pins
(shorting D+ and D-, voltage divider 2.1V on both pins, 2.5V on one and 2.1V on the other pin) the last config offered fast charge (1A)
The Phone does not seem to be smart enough to know that it needs more power and should therefore not enter slow charging mode if the power drain is higher that the power input. I have measured the current while the phone is charging and have determined that the phone indeed does charge with high current in the beginning but then lowers the current as the battery voltage increases.
My Question is then as follows:
Do other people suffer the same problem with their phone when trying to use it a lot while charging with a car charger like me? Does the phone also discharge while "charging" with a car charger? Does the phone only charge to the certain point and then stay there or even discharge again?
And the most important question:
Is there a way to make the phone stay in full fast charge mode?

I had the same problem, I changed from Stock JB to Rogers Slim JB and calibrate the battery with this https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=es
It helps somehow, but battery sometimes using the phone to much on car charger loses charge.

[TECH DISCUSSION] Is it possible to have a Dash Charge power bank?

So I'm in my junior year of electrical engineering and seeing the incredible things done with smartphones is something I really would like to be a part of one day. I wanted to discuss, considering the limits of current technology, if it would be possible to create a safe Dash Charging power bank for this device? For those who don't know how dash charging works I'll post a few links and my understanding of how it works and if I'm wrong at any point feel free to correct me.
Dash Charging - The Technology
The way dash charging works, as I understand it, is that the USB-C cable wires are made wider in diameter to accommodate a larger amount of current being passed through to the battery. The charger plugged into the wall takes on the burden of the extra voltage pushing the current through the wire and keeping it away from the phone's internal battery (which is brilliant). That means that the charger takes on the extra heat which isn't a problem because passive components are often more tolerant of heat than batteries are.
Links:
http://www.phonearena.com/news/How-it-works-Dash-Charge-fast-charging-on-the-OnePlus-3_id82646
http://www.trustedreviews.com/opinions/what-is-dash-charge-oneplus-3
The Issues
A dash power bank could be charged up exactly like the phone; with the dash charger it could fill extremely fast. However, using the battery pack to charge the phone means that the internal Li-Ion batteries of that charger will be taking on the extra heat from within the case which could:
a) shorten the power bank's life span
b) Possibly lead to unsafe power banks if it got too hot
I also see there being limitations with the power bank's ability to maintain a full speed charge similar to wall charging along with what types of batteries would be needed to provide the power output similar to the dash charger.
The Solutions
So in my limited knowledge I think that the biggest enemy here is heat generated in the power bank. I feel like the rest could be overcome with a fairly large bank of 18650 batteries. It is possible to have a passive cooling system built into the power bank for heat dissipation but that might make the battery bank difficult for users to hold on their Pokemon Go outings. Also, reducing Dash Charging specifications just a little, decreasing the speed at which it could charge the device, would alleviate some of the concern. So while you might not get 60% in 30 minutes from the wall, perhaps aiming for 45-50% charge in that amount of time would increase the power bank lifespan and total amount of charges.
What do you all think? I'll readily admit I don't understand completely how current battery bank internals work to limit over-current and over-voltage scenarios as I've never taken one apart. If anyone wants to educate me and say whether they think Dash Charging is possible I'd love to hear about it. This is the kind of stuff I imagine the OnePlus engineers are sitting around working on every week.
i think that would be too expensive to make for consumers, u figure if a dash charge block is almost $30.00 this thing would be well over $500.00 which would be too much for a regular consumer to purchase just to have a portable charger, maybe in about the 3rd or 4th generation of this technology we could see one in about 5 years, they would rather make a ton of 30.00 purchases and have you buy their charge block opposed to very little purchases of about 500.00 for power bank
It's actually already there in the market,
named "OPPO VOOC Powerbank"
attached is mine, working fine with OP3 Dash,
Price is around $45-50 - 6000mAH
Charging rate is 3,5A
and it DOES charge my device up to 60-70% in 30 Minutes
it heat up though, especially near the plug (USB C end)
this is why i use the metal based USB C adapter, so it release the heat faster

I'm going to build power bank using Dash Charge car charger. The power banks higher voltage (12V if using car charger) means less current for individual cell while charging. I have bought battery holder case 10 x 1,5V for AA batteries. http://r.ebay.com/vpShFJ (I already have plenty of Eneloop AA batteries for other accessories.) Each Eneloop has at least 1,5Ah (1500mAh) capacity while retaining voltage at or over 1,2V. http://lygte-info.dk/review/batteries2012/CommonAAcomparator.php I'm going to attach 12V socket to the battery holder case so I can use my car charger both in car as well while at camping.
Battery bank consisting of 10 x AA Eneloop has a total capacity of: 12V*1,5Ah=18Wh.
Dash chargers input is rated at 12V/2.5A so each individual Eneloop would have about 250mAh discharge rate.
My old Galaxy Note 3 had 3,8V 3200mAh battery and the capasity was ~12,2Wh. I don't know the nominal voltage of OP's battery but I would estimate it's about the same as Samsung's so the capacity should be lower than in Note 3. Maybe around: 3,8V*3000mAh=11,4Wh.
10x Eneloop batteries has a capacity to give energy for charging OP3 from 0% TO 100% at least. (18Wh/11,4Wh = ~1,6)
I think in India it's not available

We're going to need a hardware XDA for people like you. I never would have thought to string together Eneloops to make an external charger since most of your power banks contain 18650 with overcharge protection and stuff built in. The wall dash charger is spec'ed to run 5V at 4A and the car charger loses half an amp to land in at 3.5A max. Car charger voltage varies between 3.4~5V from what I can tell probably based on the car's cigarette lighter specs.
What kind of case are you using with the eneloops and what are you using for overcurrent/voltage protection?

So... can you tell me if a normal VOOC charger block charge the OP3 as fast as the original dash charger in package?
I saw it is the same current rate, but the technology, is it interchangeable?

You are right, the car charger uses lower current and is probably a bit slower. When I receive my car charger I will do some testing and will report back.
The voltage variation is needed on all chargers. When the battery is almost full the charging voltage drops.

I have ordered a case like this: http://r.ebay.com/vpShFJ
The car charger has been designed to be used as it is. The charger itself does not require additional overcurrent protection but in case of a short circuit a 5A fuse is needed to protect the wiring and Eneloops. Overvoltage is not a problem as the maximum voltage with Eneloops is going to be under 15V.

Yes it is. I've posted it in another thread as eell. Just check through my post history.
This is pure logical, since Oneplus is just a subsidiary company of OPPO, so they surely can share few technologies between each other, and VOOC/DASH is one of it,
Just make sure your usb c adapter quality is good when you decide to use it with VOOC charger.

60 W Usb Type C Power Adapter

Hi Guys
New to XDA, i was curious if anyone knew if the 60 W USB Type C Power adapter actually fast charges the 3a XL?
I bought it off this guy on ebay and he bought it for the long cable and i was wondering if the 3a XL can even handle charging at that speed. Any help would be appreciated.
Thanks

It won't charge any faster than whatever Google set the max wattage to be for the phone charger.
The phone will only draw what it needs and not how much your power supply can pump out. Although I'd suggest against using that charger for your phone.

Well evidence shows with other devices that it won't over draw. Look at universal laptop adapters, some factory adapters use 50w adapters but universal ones are sometimes as high as 80w and those laptops don't burn out thanks to protection circuits that prevent overdraw. The phone will only draw what it needs and not what the power supply is capable of powering.
It will be safe to use but personally I wouldn't use it, there is no need to use such a high power adapter not to mention it might not trigger quick charging(since those use chips in the charger to tell the phone it's a quick charger) so it could charge as fast as a regular charger.
Using a higher watt power adapter shouldn't harm the phone, but it certainly will not make the charging any faster. The phone will only use the amount of watts that it needs and the "extra potential power" of the higher wattage power adapter will simply not be used.
Basically that adapter will supply up to 60 watts, but it isn't forcing 60 watts into the phone. That's because all electric devices draw power. Another way to think of it is a mosquito on a person. A person has more blood capacity than a mosquito can handle but because a mosquito draws blood from the body, it takes only what it needs. Electricity works the same way.

might sell it then, i dont need a 60 watt charger to be honest. Might look at getting a dock for the phone so it acts like a Alarm clock with the money. It cost the original person £60 to buy it which is alot.....does come with a 2m cable which is nice but a bit too long for me and suggests its more for a pixelbook or something

S20 maximum safe charge?

I just bought a Snapdragon S20 FE. It has the SD865, of course.
I am posting this here since there are more users active that can share their knowledge and as far as I can read we have the same HW.
USB Power Delivery 3.0 charging- 25W support.
It comes in the box with a 15W.
I want to use it with my HTC QC 3.0 charger. HTC deviated fron the QC standard for their lineup but I haven't had any issues charging multiple devices.
As far as I know it's not OK or recommended to go above 3000 mA when charging. I always check chargers and cables (Type-C) to be sure I don't fry my ports or phones. I use the Ampere App on the Playstore.
Using the HTC QC 3.0 charger and HTC cable -I get. 3100 mA and 4.1V. I don't have the Samsung charger with me to test right now but it's the slower. These value go down as heat or % go up.
Are these values normal?
The phone's power controller won't allow excess current and actively regulates it when fast charging. If too cold it will default to slow charging in order to help protect the battery.

Thanks for your response. When I said i know it's not recommended to go above 3000 mA I was thinking of my experience with SD QC. I am not talking about OnePlus Dash Charge or other simillar custom solutions. Trying to figure out the PD 3.0 standard now. All my cables are good.

It's a mess. With Samsung the easiest way is to use their 25 watt brick and approved cable.
I may be wrong but don't think fast charging will not work with any power source; the phone controller actively communicates with the charger.
The phone controller actively regulates the charge curve throughout the charge cycle.
On the 10+ with the 25 watt brick it gains 2% @ minute in the 30-80% or so range if the temperature is within its correct parameters.
The 45 watt brick adds more on the lower end of the charge curve but as not near much as the wattage difference suggests.

It's a mess. With Samsung the easiest way is to use their 25 watt brick and approved cable.

I have QC chargers. I am not inclined to buy a 25W Samsung charger as I consider it a subpar product. It had to be said. After years of Fast Charging I find Samsung solution in 2020 bad. They are lagging behind OP, Xiaomi etc. But they heavily discount their phones so, here we are. Also, the Samsung cables.... but good cables are everywhere now.
Can you share your Volts and Amps from the Ampere App, used with the 25W charger in the 30-80% range?
No clue and it would vary. Might try that apk if it works on unrooted phones.
The difference once in fast charge mode isn't worth worrying about though. Takes me 10 minutes to get a 20% midrange charge.
Li's prefer short frequent midrange charge cycles.
Note: was looking that app. It looks like it needs screen on to monitor the charge.
If so that will throw off the charge curve. You can use bt and listen to Poweramp (screen off) without disrupting the curve much but screen on draws too much power.
At that point the phone will revert to slow charging.

Ampere is non-root. It shows Live data. It's not for monitoring over a long period of time. For example: I tested my 65W type C laptop charger into my HTC. Of course it went up to 3.5 Amps in 10 seconds. Pulled it off after 15 seconds. As the laptop charger is fast charge for my laptop it goes up to 5A. My phone cannot handle that.
So if you run the Ampere app and are between 20-80% at 25-35 degrees Celsius(measured at the battery sensor). It will show your charging parameters in 10-20 seconds. No problem measuring those values there.
I know 3.1 amps is not far from 3 amps and it stays that way. Maybe I am being over zealous. I don't think that 3.1 amps will ruin my phone. My experienced is based on reading about this in the early days of Type-C when HTC adopted this on the 10. It had 18W QC 3.0... in 2016. Glad I have a 15W charger in late 2020. Actually, I am glad I have a charger )).
