My g flex 2 H959 cant charge while playing games, for example like temple run or even old nokia games like snakes 97?! it will actually drain the battery while charging if i use a SAMSUNG charger and it gains around 1 percent per 5 minutes if i use my LG FAST CHARGING charger, so the question is why lose so much when you play such light games.
my note 4 never did this!

off topic: yellow on white? are you kidding me/us?
on topic: in Games the GFlex2 use the whole Power of the Snapdragon 810 and maybe the GFlex2 is not optimized for playing Games, can be, but you can help your battery:
turn down the brightness, root your phone and use Greenify and disable or delete bloatware and useless google stuff, force your SD 810 to a lower frequency and so on

You can try if you dont already custom thermal settings from user probaina.
It's your usb cable!
The cable quality is very important. Even if you have a good 5V charger, it's useless with a slim and long cable.
The more resistance (ohm) there is on your cable, the more intensity you will lose (A). And the resistance goes by two factor, cable thickness (AWG in USA and mm² elsewhere) and cable lenght. The thinner and the more lenghtful is the cable, the less Amp will go thru.
I have a usb voltmeter and ampmeter so I can give a value on each scenario.
I have a usb charger that can deliver 2.1A and 5V. With a normal cable that was bundled with blackberry (I got them at work) I get 690mA. Cable is 1.2m long and 28AWG is marked on the cable.
With the same charger and a 50cm long cable and 28/22AWG gauge (I suppose it's 28AWG for the data cable and 22AWG for the charging cable), I get 1.29A
With a 3m cable (yes it's long but I have a purpose for it) of unknown gauge, I get 250mA, sometime 300mA maximum. And this intensity it's just a little more than 1W. Even overnight I lose battery percentage.
But with the LG Fast Charger it's all different. It's not labeled Qualcomm Quick Charge 2.0 because it don't deliver 12V. The LG charger deliver 5V and 9V while Qualcomm spec for QC2.0 must be with 12V too. Anyway lets say it's a quick charge 2.0 charger because it act like one.
With the LG charger, with the 3m cable, I have 8.2V and 1.2A which is nearly 10W, more than enough to play and charge at the same time.
I can explain why the 9V tension help with the high resistance of the cable but to make it short it's the same as the big high tension cable in country side, the high voltage help for the long distance even if there is very big cable.
The usb cable provided with the Flex 2 is very good, it's 20AWG on the charging pair. But if you can find shorter cable it's even better (Western Digital cable is very good but to find one of their device bundled with a short and tick WD cable that is not mini usb and not usb 3.0 is very hard).
If you want the fastest charging speed you have to buy a QC2.0 certified charger and a 22AWG or 20AWG short cable. For daily charging I recommand using your old 5V charger (your samsung one).
Thank you so much for this answer bro

The thing is i have no complaint otherwise, my lg charger is pretty blazing fast with no games, its like 1 percent per minute fast, but as soon as i play games everything is lost and worsened!
thank you though for your answer. May Allah guide you to islam!
bro i cant root, its 5.1.1 no root has ever been discovered

What you describe is different from the original post.
First you said that with a 5V charger (samsung) you lose percentage while playing but it was ok with the LG 9V charger.
then you say while answering to me that even with the LG charger you lose percentage but even if your cable is crap, the LG Fast Charger deliver enough power for any situation.
So you really lose percentage while playing with the LG Fast Charger?
And please, no proselytism.

nope but with the lg charger it charges at around 5-8 mins for 1 percents, excuse me but that is wrong , it shouldnt
you meant it's not fast enough or too fast? I don't get your point.
If it's not fast enough, then do not use the phone while it charge or get a Quick Charge 2.0 charger that can do 12V.
If it's too fast, roll back to a 5V charger.
I was always under the impression that it is really bad for the battery to use the phone while it's charging. Perhaps just plug it in and let it charge while not using it is the best solution to charge faster.
I tried a Quick Charge 2.0 charger. The one supplied with our Flex 2 is not a QC 2.0 because it's only 5V and 9V. It still use QC 2.0 spec as at first it's 5V and when it identify the device it deliver 9V but it's not QC 2.0 certified as it don't deliver 12V.
So with a QC 2.0 charger, it deliver 9V too to the Flex 2. That mean that even if the S810 is capable of 12V charging, it's up to manufacturer to specify how it works. It won't charge at 12V.
I don't have another recent snapdragon to test the 12V.
Same!!!
I know its not good for batteries to be used while charging, but for example, i also have a Moto G and its okey playing while its connected to an outlet.
But with my Flex 2 its different, it charges incredibly slow, and worse... it gets HOT! REALLY HOT!
I'm trying now the thermal adjustments suggested by probaina.
Hope it works.
I'm going crazy...
What? My ATT version charges incredibly FAST! Sometimes it gets warm, but nothing I would be concerned about and it's even less after 5.1.1 update. Heck, my M8 gets just as warm if not more.
LMELME83 like OP you have to clarify things, is it slow to charge with a normal 5V charger (like the charger from your old phone) or is it also slow to charge with the charger provided, the LG Fast Charger?
For the 5V charger, the usb cable make all the difference.
For the LG Fast charger or a Qualcomm Quick Charge 2.0 charger, it's all about if the charger recognize your phone and there is no way to tell it on the charger or the phone. You have to use a usb voltmeter. I can recommand one that can take 12V.
Anyway it's normal that the LG G Flex 2 get warmer than the Motorolla Moto G (regardless of the generation because there is 3 or 4 different moto G). Any entry level phone will be colder, like a Core i3 will be colder than a Core i7 even if no one is crazy enough to use a core i7 with the stock heatspread and fan.
Hey guys,
I am looking for a usb-c pd compatible battery pack with a small form factor. capacity is not my main concern, but the form factor and a fast charging speed is. However, I can find none.
I can find lots of quick charge 2/3 battery packs, but are these safe to use? Thanks for your help
I think its OK with non-PD charger.
It won't enable rapid charging if you are not using PD charger and will only give you normal 5V2A.
Unfortunately USB-PD chargers seem to be in their infancy where most USB-PD chargers seem to have faults and some may even kill your pixel.
Belson/Nathan K have made a list of cables and chargers they have tested for the Pixel here https://docs.google.com/spreadsheet...x9dMDWqENiY2kgBJUu29f_TX8/edit#gid=1288176877
If I was you I would go for a non PD 5V 3A charger as it will charge at 15W which is only 3W of what you could get with PD Charging and often you would end up with less anyway.
Just keep using your existing battery pack with a USB-A to C cable with 56 ohm resistor (like the oem cable)
Hello guys.
I cant get PD charging to properly work on my Find X2 Pro.
I have a 45W PD Powerbank, but it only charges very slowly (1% every 5 minutes). Only with the USB port I get decent speeds (w/o PD) (about 10W).
10W is still very slow I think, considering the not-so-great battery life in my experience. I am going to travel in the near future, and I need a good battery.
Does this phone support PD? What is the maximum speed it can charge with power adapters/powerbanks without VOOC?
Oppo uses its own proprietary charging system (super vooc) and not PD, I have also had very slow charging if I dont use the original brick and cable. maybe try using the charging cable they gave.

Yes I know, but OnePlus phones for example also have VOOC but also support PD.
I tried every cable I have, the original cable is USB-A to USB-C so that one is not for PD. I get max 10W out of that cable from my PD powerbank.
i use Xiaomi 10000mah powerbank with QC2.0 onboard. And my Oppo chardging fast about 10-15% for 10.minutes.
Hello
So a couple of weeks back I upgraded to the Poco F2 Pro 6/128GB from my Mi 9T.
I have been using a magnetic charging cable with my Mi 9T, with a little magnetic part permanently in the usb port for convenience with a standard QC3.0 charger. Worked great and charged fast at 18W.
I wanted a similar solution for my Poco F2 Pro.
So I have done some testing and the results might surprise you.
Poco supports 30W Mi Turbo Charge which seems to be a custom Xiaomi charging protocol and does not seem to play nice with standard USB PD3.0 Protocol.
I have done charging tests from ~5-20% battery for maximum charging speeds and tested the actual charge rates with a USB Voltmeter
Voltmeter:
https://www.ebay.co.uk/itm/USB-Mete...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2648
Test 1: Original Charger and Cable
Result: 30W Mi Rapid Charging (~9.6V, 3.1A) As Expected
Even tho the original charger is rated at Max 33W, Poco only charges at 30W Max.
Test 2: 60W USB PD3.0 Charger + 5A Type C to Type C Cable
Charger: https://www.amazon.co.uk/gp/product/B0824S38VC/ref=ppx_yo_dt_b_asin_image_o07_s00?ie=UTF8&psc=1
Cable: https://www.amazon.co.uk/gp/product/B07QPNRGYH/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
Result: 18W Standard Fast Charging (~9.2V, 1.9A)
I did multiple tests to check if the charger is legit (which it is, many of my friends use it with different devices and it works great) with my brothers Pixel 4XL, and my friend Xiaomi Mi 9.
Pixel Charged at 18W, Mi 9 at 27W.
The phone did not charge at 27W (~9V 3A), even to it does support PD 3.0 charging.
Test 3: Original Charger with a 3A Ugreen Magnetic Cable
Cable: https://www.ebay.co.uk/itm/Ugreen-M...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2648
Result: ~25W Mi Turbo Charging (~9.6V, 2.6A)
This is very interesting since it does trigger the Mi Turbo Charge, it is not the full speed charge like with the original setup.
Original setup also has a charging animation, with the % increasing at a steady speed.
With the Ugreen Cable, there was no animation.
Test 4: Original Charger + 40W Huawei Supercharge Cable
Cable: https://www.amazon.co.uk/gp/product/B08CR7W2T1/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
Result: ~25W Mi Turbo Charging (~9.6V, 2.6A)
The original Xiaomi Cable is a 5A Cable, so I thought id try a Huawei Supercharge Cable, but it ended up charging the same as a 3A Ugreen Cable
Test 5: 60W USB PD3.0 Charger + 5A Magnetic Type C to Type C Cable
Charger: https://www.amazon.co.uk/gp/product/B0824S38VC/ref=ppx_yo_dt_b_asin_image_o07_s00?ie=UTF8&psc=1
Cable: https://www.amazon.co.uk/gp/product/B08HLN27DP/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
Result: 18W Standard Fast Charging (~9.2V, 1.9A)
Again, standard 18W fast charging, not 27W as you would expect.
Conclusion:
From my testing, the only way to charge the Poco at Maximum speed of 30W is with the charger and cable which I find very strange. Does the original Xiaomi cable have a custom Xiaomi chip which handshakes with the charger to get the full 30W Mi Turbo charge?
With a PD3.0 Charger, I was only able to achieve 18W of fast charging, again very strange, since Poco should support 27W (~9V 3A) charging with any PD3.0 Charger.
I have settled for a setup with the Ugreen Magnetic Cable and the Original Charger for convenience, ease of use and preventing the USB port from being worn out. I am loosing about 5W of speed, which does slightly increase the charging time. (I charge my phone to ~85% max)
(If there is something wrong with my methodology let me know and I will re-test if needed)
I approved with an Aukey 29w Fast Charging charger (model pa-y7) and the same charge at 18W, even with the type-c cable on both sides (Baseus brand cable up to 60W)
It seems like Xiaomi cable and charger have an extra pin. That might trigger and power the turbocharge

I don't know at which rate it charges but it triggers Charge turbo animation with the % increasing at a steady speed with almost any proper USB-C to USB-C cable.
I've also found that if you launch the CIT on the phone by tapping on kernel version 3 times on settings->About this phone->All specs
and go to the charging test (number 24) you can check which protocol is being used
If you use any QC3.0 charger it says USB_HVDCP, which triggers fast charging but not the charge turbo animation.
If you use a regular PD charger it says USB_PD which also triggers fast chargingbut also not the charge turbo animation.
If you use the original setup it also says USB_PD which means that extra pin it has on the USB-A connector is wired in a weird way it actually negotiates usb PD protocol, which I can also confirm because I connected it to a Thinkpad T480 and with the Lenovo Vantage software gets 27W charging, which is not possible with any USB-A to USB-C cable and QC3.0 charger.
Which may mean that maybe Xiaomi didn't want to pay for the QC4.0+ chipsets or something and did some weird stuff to get PD through QC3.0 by that pin and through the F2s software reducing the cost of the charger in the box and whatever else. As for this GaN 65W charger I have no idea on how they pull that off but is a proper PD charger
Since the update to Android 11, a set of cables that previously triggered the Turbo Charge, now suddenly work only as Fast Charge.
They were a bit slower than original before, but now they are a lot slower.
I only have the Accubattery measurements:
cca 4000 mA average on Android 10,
cca 3000 mA average on Android 11.
While the original charger + cable shows about 4500-5000 mA average.
They really managed to screw this device.
On ArrowOS my device charging at 1.8A and 7.5V with original charger and wire... so it depends on software. But anyway I don't want to downgrade from perfect OS to buggy MIUI only because of that.
I also have seen a weird change in charge speeds..
Used to be totally fine but it seems that for a while now the speeds are very slow and quickcharge isnt working anymore..

hey have the same problema. here. teh only way to get fast chager is with the original charger al cable. PD charger give me fast charge. but all my other chargers that gives me fast charger in other devices gives me NOTHING now.
original charger 4300 ma,
PD: 1200 ma
fast chargers QC 3 and others: 230 ma !!
****ty old chargers : 230 ma.
so what the hell? I was thinking that I screwed the port of the phone with magnetics cables before read this.
Just my 2 cents here. Don't try to charge this phone with super fast chargers. Mine developed the well known fault that you needed to press the corner of the phone to get it to start charging. I even opened it and put a bit of a tape behind the ribbon cable connector (as some guy suggested on YT). It started charging again and then after a couple of weeks and a few more quick charges it stopped charging at all. I guess heat affects the connector or some element on the board. I've just ordered a new usb board and ribbon cable from Ali and if the phone comes back to life again I will never ever use the original rapid charger that came with the phone.
My Poco F2 Pro charges fine (and very fast) with a USB-C to USB-C cable connected to a USB-C fast charger such as a Samsung. But if I try to charge it with a USB-A to USB-C cable connected to any charger, the phone only draws 0.5A ( I have a USB power dongle to check this ) and that's not fast enough to actually keep the phone charged when in use.
Every other phone I've tried will at least draw over an amp, even those which support fast charging.
I've tried multiple chargers, multiple cables, and nothing except C-C with fast charging will actually charge the phone.
Is this normal behaviour for the phone, or do I have a fault with mine. (It was bought second-hand with a warranty, but no charger or cable in the box).
No it's not normal, mine charges at least at QC3 speeds with various compatible chargers, powerbank and cables. Even with Huawei's fast charger, which seems not to be fully compatible, it charges about 2A (measured in accubattery).
It has a strange behavior if it's like that. What about original cable and charger, that's A to C, should charge very fast.
I had another issue regarding charging, whichever charger/cable I was using (let's say max 5V/2A), in accubattery it was measured around 3A, and the charger would overheat like crazy. You know when you want to charge slower, all what they tell you on the web is to use a less powerful charger... and this is what I did, but not with great results though. On my previous phone it was working just fine. On my wife's Mate20Pro it's also working well, but not on F2Pro. Even if the cable was rated 3A and I would connect it to the original charger, it would still draw 5A from it... Only way to solve it was AccA apk so I limit the current that the phone draws and I'm happy.

Unfortunately I don't have the original charger and cable as it was a used phone which is otherwise in perfect working order. I've had no problems with c-c fast chargers, but nothring else works.

Just search and buy original charger if u want full charging speed, one guy made a great test of different chargers and different cables on this phone, check this here https://forum.xda-developers.com/t/poco-f2-pro-charging-study-how-fast-does-it-charge.4189013/
There's something wrong with his device.
0.5 A is too low for any charger.
