I just bought a generic USB wall charger and it's taking much longer to charge than the htc charger that came with my EVO.
I'd like to determine the amps/ma the charger is actually putting out. I don't have a multi-meter, so I am hoping there is a hidden menu or app which will tell me what the phone sees.
Any suggestions?
You can download aLogcat and watch for the current usage, it should post it every so often. It should also say on the charger somewhere too, the stock wall charger is 1000mA
I tried this and found nothing showing charge rate, only the battery percent.
A standard usb wall charger should equal how long it takes to charge if you were plugged into you pc. If it is taking longer than that then you got a super el cheapo charger that puts out less than 500ma (milliamps).
I would be carefull too, cheap usb wall chargers are not know to output clean power and have killed devices. By overvolting/charging them.
I have been doing some testing lately with the htc charger and a pc and have come to the conclusion that the htc wall charger pushing 1 amp (1000ma) charges the battery too fast and doesnt allow for a "strong" charge. Meaning your battery will drain faster. The htc charger is, i believe not meant to be your everyday charger, only a boost charger to get you charged back up quickly.
This is common battery knowledge when it comes to charging... you can charge a battery too fast, and a slower; 500ma "trickle charge" is much cleaner and better for your battery.
Some maybe argue this, and thats ok, these are just my personal findings.

I'm not seeing that info in the log either.
The charger had a weird range of 250-1000ma.
Yeah I think I'll invest in a better charger just to be safe.
Thank you both for your replies.
I bought the below car charger because the cheap generic one I had from an old phone couldn't keep up with the drain from the screen when running sat nav.

This also doesn't work, it loses a percent of charge every 10 minutes or so, while I'm aware this isn't alot and I can probably get anywhere in the UK on a full charge, the fact is I want my phone to actually be charging while it's plugged in as I don't always have a full charge and I may need it topping up on my journey in case I don't have another charging opportunity for a while.
I cannot find another genuine samsung product that claims to be compatible with the s2 (indeed the above "genuine" charger doesn't appear on Samsung's website.) There is one on their site (P10CBE In-Car Charger) however it claims to be only compatible with the galaxy tab. While I know it simply has a USB socket for use with any data cable, I'm worried it may damage the phone if rated too high in amps (700mA to 2A is a big jump.)
So I have 3 questions...
1) Is the tab charger safe to use, and does anyone else have this and can confirm it can keep up with the screen permanently on with google navigation running.
2) Can anyone suggest another brand that they have experience with it definitely keeping up with the charge on a galaxy s2, running screen etc.
3) I quite like the look of the official Samsung car mount, can anyone confirm if the charger included with this can keep up etc (also if you know what ampage it's rated to as I can't find this info on the product data.)
Many thanks if you take the time to reply to this, a bit lengthy I know.

Use siyah's kernel to increase the charging current, how high you can go is anyones guess. Stock kernel supply's 450mA when plugged into a usb port and 650mA when plugged into a charger, i set mine to 800mA for both and all seems fine so far.
I have used a motorola car charger and this has actually worked better that the original samsung car charger, charges faster, and has a cool blue light. since the micro-usb is non-proprietary, you have lots of options.
Using an Official charger, better than those cheap ones that fail to keep the battery topped up while using the phone as a satnav.
I have a Sony Ericsson Original AN401 Compact Car Charger and it charges when using satnav.
The main problem with the cheap adapters is the output current, it tends to be too low for GPS. Make sure it is regulated & 750mah or higher.
Hi everyone,
I have a problem with my original wall charger that came with the phone. There seems to be something wrong between the cable and the connector you are plugging into the phone. I need to have the cable in a specific position for the phone to be able to recharge.
The question is, is there any better charger than the original samsung one? I could probably get it replaced as it still is in warranty, but I don't like how slow it recharges the phone. If I am running a 3D game the phone is slowly DISCHARGING even when plugged in to a wall charger.
I noticed the charger has only 500-700 mA output. I had an older htc charger which had 1000 mA output. Would a charger like this recharge my phone faster? I have seen some posts about non-samsung chargers not being able to recharge the battery fast as there is some kind of protection built into the phone.
I would also consider buying a wireless charger if it was available for a reasonable price.
Are you all using the stock chargers?
Thanks in advance for any help.
you can read this thread: http://forum.xda-developers.com/showthread.php?t=1721677&highlight=charging
Just to make sure it is the charger's fault, does the phone charge normally if connected to a computer, from the USB port?
Thanks for the link.
Yes, phone charges and transfers data from USB without any problem, so it should be fault on the charger.
Reading through that thread, I guess there is no point in buying a more powerful charger.
as i said there, i use a nokia 1200mAh charger and the charging time is more than 2 hours, so we have to deal with it. The thing you should care of is the quality of the charger to avoid the touchscreen known problems
Imho you don`t need better (more powerfull) charger because of the hardware limitations. What you should do is to try any other microUSB charger just to see if that solves your problem. So if any of your friends of family have other samsung or nokia etc. phone, thats charging with microUSB, plug it into your phone to see if it solves your problem. You will know what to do next if it does

how do I check the quality of the charger?
Sooo I just copped the Aukey 18W charger and I think it charges faster than the stock LG charger but I'm not sure. Isn't the phone supposed to notify me if QC has activated? I tried it on my G3 and it doesn't even show on that either. Does this thing even work in this? Also, main part of this thread was to start a poll on what you guys think the most effective QC is. Check out the poll.
A QC 2.0 charger will be about 20% faster than stock. Doesn't matter which charger you use. There are several good ones. And several threads on this already.

There obviously are but that wasn't my question. I asked which is effective for the G4 along with a poll. You answered nothing. Read the OP before commenting please.
I've tried every one you have listed plus the ZeroLemon and a Samsung quick charger and they all perform the same, a 20% increase over stock just like I mentioned in my 1st post.

Now this is a helpful comment right here. Thanks. I almost wasted my money buying a different one.
I took a chance at this no-name Chinese Quickcharge 2.0 charger on eBay because Aukey refuses to ship internationally from Amazon, and I was pretty skeptical but this thing actually works. No pops or sizzle sounds emanating from it and it charges much faster than the one that came with the phone.

I just recently bought an 18w Anker quick charge wall charger and it works great. It's faster than stock and doesn't make any noises like the one that came with my phone. What I like about this one is there is a light that turns from blue to green when it recognizes a device that supports quick charge (signifying that it is charging at higher volts). So far I am very pleased with this purchase, though I imagine it is just as fast as most other quick chargers out there. ?
Works great with Samsung Adaptive Quick charge... Also works much better with V10b-EUR-XX than V10a...
I read here: http://www.phonearena.com/news/The-LG-G4s-battery-recharges-23-faster-with-a-QuickCharge-2.0-charger...-or-a-Samsung-rapid-charger_id69692
And it said, that using the "QC2.0-enabled Motorola Turbo charger" it charged the G4 from flat, in 98 minutes.
It also said, that using the "Rapid Charger included with the Samsung Galaxy S6" it charged the G4 from flat, in 99 minutes.
So to me, that equals near enough makes no difference, 1% per minute of charging.
The Anker PowerIQ chargers also charge the G4 at the same pace, from flat to full in around 99 minutes. In my test, I was connected to wifi, and I used the phone as little as possible, but when I did start using it, of course it immediately started charging a lot slower. I have heard that it deliberately does this to avoid too much heat being generated, I think that was a post on here somewhere, but I'm not sure if that's true or not.
I did tweet LG UK to ask if the G4 supports the 9V tier of quick charge 2.0 , but have yet to get a reply.. Maybe I should ask their support instead.. (Although on that point, I don't think it does, due to the tests been performed with a proper QC 2.0 charger, which still took 99 minutes. The fact that the Anker is only 5v, yet charges at the same speed as a QC2.0 charger, certainly implies that the G4 is only using 5V even if 9V is available on the charger..)
I do want to say though how much I like the Anker products, especially the recent ones I've bought (the USB 3.0 hub with 3x PowerIQ ports, and some cables to go with it). They feel really well made, a solid bit of kit to be honest.
But anyway, hopefully this post was useful.
I've only tried the Aukey and I'm very happy with it. So much so that I picked up the 10000mah external battey as well. It also charges quite fast.

The QC spec only calls for increased charging speed from 0-60%. After that it slows and then trickle charge kicks in when it's close to 100%. Going from 99% to 100% can take 3-8 minutes in my observations.
Unless LG relaxes the heat threshold to let the phone heat up a little more, we won't ever see true QC 2.0 on this phone.
The Aukey one most definitely does not quick charge the G4. Ill link to this other thread if I can find it again, but every single person with the Aukey charger said it did not quick charge their G4's. Several of them tested with USB volt and Ammeters. The Tenergy (and by extension, the Anker quick-charger, which is a re-brand of the tenergy) seems to work at 9 volts. Its a shame, the Aukey charger is pretty darn good looking and comes in a slick package. Its very odd because the Aukey quick-charging external battery on the other hand, does just fine quick-charging the G4.
Platinum 2.0 with QQC (Qualcomm Quick Charge )
Purchased at Best Buy on 6/26 for $24.99 What I have found is that it charges faster below 70 % and about the same as LG standard above 70 %. From te comments I've read I think LG is limiting QQC to protect the phone. IMHO
Using the Samsung quick charger from my previous phone (Note 4), and it works great.
I have a "Zerolemon" brand. It works good. I have another for the car... but not sure what brand. Like always, you have to make sure you use a quality cable before it will work. Coming from the G2, I pretty much already replaced the crappy cables.
I use ZeroLemon and Motorola Turbo. Full charge from few mins to 1.5hr instead of 3-5+ hours using 1A chargers
EDIT: USB Tester shows 8.99V 1.32Amps
I just got my Tronsmart 54w 1x qc 2.0 + 3x 2.4mA car charger from amazon. Works as well as the motorola turbo wall charger. Took about 30 mins drive to work to get from 57-97%. Ampere messured approx 1970mA charge rate at start.
Impressive packaging and excellent build quality. Came with thick gauge usb cable. I got at a good price following a slickdeals post.

I don't know about you, but my phone has hit around 112 degrees F when charging. I don't think I want it getting any hotter.
hi,
i've bought a wall charger from Aukey, and a car charger from Tronsmart, both compatibles with Qualcomm Quick Charge 2
http://www.amazon.fr/dp/B00RCM0TGY/ref=pe_386181_40444391_TE_item
http://www.amazon.fr/dp/B00XW0DET4/ref=pe_386181_51767671_TE_dp_1
and with theses 2 chargers, i have the same "issue" : my H815 charges at 6V 1,10A.
Can't these chargers go upper? 7,5V, 9V, 12V?
I received a zerolemon for review promotion but I don't think I'll use it for the daily usages. It is packed in my go to bags when I need quick charging but haven't really used much since LG provided extra battery pack dying the June promotion.
That being said I've noticed about 20% faster on ZL QC.

So I'm having a problem (I think). Until now, I charged my S20ultra with its very fast charger and with my wireless anker (10W model) connected on my usb pc port. While connected on USB port, I know the charge is very slow (takes like 5+ hours from 0 to 100%) since it uses only 5W but I dont mind since it's wireless.
Today I conncted my anker wirless to a normal charger (its the one coming with samsung A51, supports fast charge). I thought that would speed the wireless charge up (since my anker is 10W but on pc usb port it can only use up to 5W), instead its still slow. Using accubattery sometimes i see the actual charge rate rarely go up to 800mA but almost all the time its about 200-400mA. My phone right now is at 54% battery so its not even at the end of a charge (at the end i know it slows the charge up with all chargers), accubattery shows 13%/hour charge which is very slow. Anyone know why this is happening? Why isnt my wireless anker using its full speed?
PS Android says its using wireless rapid charge, so its not like it doesnt recognize it. I also tried removing the cover but doesnt change at all.
Not sure what output your A51 adapter does, but for full 10W output on the Anker wireless charger it must be plugged into an adapter that does 9V-2A output and QC3 compatible.
You can find the output on the wall charger by reading the very small print on it

Thank you!! Well this might actually be it, the A51 adapter is 5V-2A or 9V-1.67A. I guess this might be the reason then... since you've been so kind and you have exactly the same wireless pad I use, can you please link me your adapter? I was thinking to buy this anker one: https://d2211byn0pk9fi.cloudfront.net/spree/products/57202/product/A2010311_ND06.jpg?1505382537 Has 9V-2A and its QC3 but just to be sure i'd rather go with the one you got since its working. Thanks a lot!
I use a Motorola 27W PD adapter that I had lying around from a previous device but that Anker one you linked should work no problem.

Thank you! One last question... do you think the lack of usb-c port might be a problem? I noticed your adapter uses it but my anker pad has a microusb-usb b cable so I cant use an adapter with usb c but just the old normal usb port... was wondering if that might cause problems. I guess you use a usb c-microusb cable to connect your anker to motorola charger right? Thanks!
Not being usb C on the pad shouldn't be an issue, comes down to how much juice the wall adapter pushes out . And yes I use a USB OTG adapter (usb C male to USB A female) to work with that moto charger. I think you should be fine with that Anker charger you linked and then using the cable that came with the pad.
I only use wireless charging over night so I haven't really tested to see charge rate as I just let it go as I sleep, I'll make an effort to watch it sometime to see what actual rates I'm getting.
Hope that helps .

Just an update... i received the charger today, but even with this one so far it doesnt seem to change much, it charges like 12-14% per hour. If possible I'd really love to hear from you if your experience is different, I know its hard since you just leave it to charge during night, but maybe if sometimes you happen to charge it for an hour or so during day would be interesting to see if you have similiar results or a faster charge... thanks again!
This is what I'm seeing, granted I was already charged to 60% before I took this screenshot. Also I have an S20, so smaller batt than its big brothers ..
No charger (wireless or wired) will ever reach their theoretical charge rates ... I know me using an OTG adapter into my PD charger leaks power almost as much as wireless charging itself . Convenience is why I use it though..
I think for the best/fastest Qi charging, we have to get the Samsung official charging docks/pads.

Thank you man... one question, does it stay at around 1100-1200mA all the time? What I noticed is that my phone sometimes goes up to even 1400-1500mA but it stays like that for a very short time, few minutes, then rolls back to 200-400 most of the time (so very slow). If your phone is always charging at least 1000-1100mA then for sure theres something wrong with me, but i read a lot of other people seem to have problems with s20/s20+/s20ultra wireless charging, even with the samsung original 15W charger. Thanks!

Mine is Exynos, and even the 20+ from this other guy having problems with samsung own 15w wireless is exynos. Would be sad if this was just another problem with exynos, not being able to charge it as fast as with SD. You've been very kind, the last thing you could do is maybe sometimes when you charge it, see if accubattery is really always at 1000mA or more, or actually drops by half if not more for you as well sometimes. I'd be happy to even have a steady 700-800mA charge, problem is that its almost always under 500, but for a very short time i DO see it going up to 1400 so it means the power provided can reach the phone, it just doesnt last, i really wonder why.
If you could check once in a while would be really appreciated. Thanks man!

It's been solid @ this rate till ~60% then drops down to 1000-1200 ... haven't seen any spikes or dips, it's pretty consistent. Don't know what to say, it's a bummer that your device seems to have issues with Qi charging. And doubly sucks if it's an issue w/ Exynos devices. Wish there was another person here who could chime in

Seems everything is in order with you. I also wish more people would jump in sharing experiences, sadly it seems not many of us charge it with wireless. Other day I was searching online and on Reddit I found some s20+ exynos user with the samsung 15w wireless original charger with the same problem, there would be almost no difference between that charger and a 5w one. The chances that its both his charger faulty and my s20 ultra as well are very low (beside my s20 with cable and 25w samsung charger goes to full in about an hour, and if it was a problem with wireless it wouldnt charge at all all the time ), so maybe the problem could actually be exynos but who knows... anyway thanks a lot for your help, lets hope someone else jumps in this thread. I was almost rdy to buy the (very expensive) 15w samsung charger but at this point im not even sure its really faster.
Update: just put on the pad to charge, was at 26%, went to 32% and accubattery showed always 1400-1500mA. Now its stuck below 500 again, temperature 36.4C so not even hot to drop. I really am gettin pissed off at this, how is it possible it charges full power for a short time and then drops.
Another update... Anker just replied to my email sent days ago about my problems with the charger, here it is:
"Recently, our various markets have feedback that this S20 cannot achieve fast charging. The specific reason is that our engineers are still testing. Because we did related tests before it was put on the shelves, there was no problem. But now it is confirmed that there is a problem, so we recommend that you do not buy new products for now."
So apparently there is a known problem, altho im not sure hes talking about s20 in general or about s20 ultra since i wrote i had an s20 ultra in my original email. Also its not clear if its just markets with exynos or those with SD as well. But it does seem that there is a problem that they know about...
