I started using "Battery Monitor Widget" free by 3c
a few days age.
I noticed that the charging current using the Samsung plug in charger was about 300 ma higher than the charging current using other USB chargers. I read on other battery threads that Data + and - are connected on the Samsung charger to prevent the USB screen from appearing. I wanted to know weather the connection of D+ and D- had any thing to do with this so I opened up one of my other USB chargers and soldered the two middle pins (d+and d-) together. After making this change, I got an additional 300ma out of this charger.
According to Battery Monitor Widget, when charging the battery from 50%, the Samsung charger was putting out around 1180ma. Unmodified USB chargers put out about 820ma. The max current output listed on the charger makes no difference in the result.
The charging time from 50% to 100% was reduced by 25% using chargers with d+ and d- connected.
This is actually very interesting. I have been trying to figure out how to make the phones charge faster and have been searching for higher ma chargers. I wonder if there is a way to modify the cable to achve he same results.
I've noticed that sometimes plugging my phone into one charger triggers usb mode but other chargers do not.

Nope not useful at all - nothing new.
1) It's not 300 mA more. CurrentWidget has a 1.83x scale factor. Covered in the thread above. It's 125 mA more.
2) I'm fully aware that shorting D+ and D- together puts you in AC charging mode, in compliance with revision 1.2 of the USB Battery Charging specification. I'm also fully aware that iPad/iPod/iPhone chargers get treated by our phone as a regular USB port and not as an AC charger.
USB charging is 475 mA. AC charging is 600 mA, unless you're running one of my kernels with charginghacks - in which case it can hit 800 mA when the battery is below 4.0 volts.
Right now, I don't need any more data from the Infuse. I need someone with a Captivate or i9000 to run CurrentWidget tests, I'm looking for VERY specific things.

Please don't post in that thread unless you own a Captivate or i9000 and are able to collect the data I'm asking for. It's not a generic battery research thread - I understand a great deal about how our device works and don't need any more data from Infuse owners at this time. What I DO need is more details and testing with the Captivate since I see many people claim they charge significantly faster despite the charge current limit being the same.
Also, if you had read the linked thread you'd see (as I mention in my post above) - this isn't a new discovery.
Settle Down, The AC charger mode is not covered in the Infuse General thread. It is worth mention here to got the word out. No one is trying to take over YOUR battery thread.
Progress?

Hi entropy,
Im a noob to the forum, but have read your other thread that requests info from captivate users. Sorry not a captivate user here as I am a infuse 4g user with the same freaking complaints from everyone else.. slow charge up time, fast discharge.
Just want to know the update of your investigation and if any progress has been made with improving the battery charge/discharge. I ve been able to improve the discharge rate with JuiceDefender and watch the progress with JuicePlotter from the market. But that only controls the discharge and not the important aspects of the battery as you seek.
Also, minor point I noticed, is when there is a difference when charging the phone in plane mode versus Juicedefender running (and w/out it). Would you like some numbers? I realize this might not be new for you considering the info you posted about charge being split depending what the phone is doing. So, it makes sense if its in plane mode it will charge up faster.
As per my title, can anyone confirm if the UK version of the Sony Z3 D6603 is Quick Charge 2.0 compatible?
If so I can't find a Sony Quick Charge 2.0 adapter either?
Many thanks,

Hello figo_rulz,
I can comfirm that the Sony Xperia Z3 D6603 has Quick Charge 2.0 built in, as the Sony Xperia Z3 Consists of the 'Snapdragon 801 chip' which is believed to hold the Quick charge 2.0 Capability (You can also check on their website: https://www.qualcomm.com/products/snapdragon/quick-charge)
Sony sells a 'Quick charger' also here's the link listed below:

So just reading up and it seems EP880 adapter which is what all UK Z3's have is what the adapter also is with the EP881. The only difference is actually the cable as this has two ferrite cores which prevents interference and the EP880 has none. so ideally I would just need to look for the cable as my adapter is capable of this quick charging 2.0! Apparently the cable we have is the EC803 without the two ferrite cores and the one you need to enable quick charging 2.0 is EC802!
The search goes on for the cable!
I use my note 4 quick charger and it works
How fast is it?

Despite of what Sony says in this link:
http://talk.sonymobile.com/t5/Xperia-Z3-Z3-Dual/Quick-Charge-2-0/m-p/973745#U973745
I have tested different chargers and came to the conclusion that Quick Charge 2.0 does work with the Xperia Z3 (at least with my variant, the D6633). I could verify that I have happily charged my Xperia Z3 from 10% to 100% in a little less than two hours, using a Motorola Moto Maxx (Droid Turbo) charger, which is a charger with Quick Charge 2.0 technology.
Moreover, I have also verified the charging currents with the Battery Monitor Widget app, and noticed that using different chargers can drastically change the charging speed of our phone.
I am going to take some screenshots tonight when I put the Xperia Z3 to charge and then upload them here tomorrow.
SONY Quick Charger EP881 is NOT QC2.0 compatible/certified. I own one & shipped charger seems better but I hv no clue why.
OK, here are the results for my charging.
Up to 40%, I have recharged my phone with a Moto Maxx (Droid Turbo) Quick Charge 2.0 charger, then I changed to the stock/original Xperia Z3 "quick" charger (EP881), which I have no idea why is named "quick" charger by Sony...
Notice the Moto Maxx charger got me a 1600ma/h charging, which would charge my phone in about 2 hours. The EP881 Sony Stock charger got me around 900ma/h charging. That would led me to a total recharging time of more than 3 hours.
I still could not test different Quick Charge 2.0 chargers, but I can assure that the Moto Maxx/Droid Turbo one DOES work with the Xperia Z3.
It IS QC2.0 compatible, HOWEVER: The charging setup is such that you'll only see a benefit in cases of charging while the system is under load.
The Z3 kernel limits battery charge current to 1.5A (approximately 0.5C) regardless of what charger is attached.
If you attach a non-QC2.0 charger with a VERY high quality cable (less than 3 feet with 24 gauge wire or thicker), you'll typically see 1.5A of battery current WHEN THE SCREEN IS OFF. Even in that case, you won't see consistent 1.5A input into the battery (use CurrentWidget)
Turn the screen on and you will NOT see 1.5A of current going into the battery with a non-QC2.0 charger, as the battery power in is (Vbus input limit - system load)
However, if you have a QC2.0 charger, even with a thin USB cable that would normally lead to extremely poor charging performance, you'll see 1.5A go into the battery under almost any load condition.
TL;DR - It's QC2.0 capable but you'll only see a difference when the device's screen is NOT off. If the device is plugged in to a high-quality USB cable and the screen is off, you'll see only minimal differences.
You'll see a MASSIVE difference if you use one of these cables - http://www.amazon.com/StarTech-com-Micro-USB-Cable-UUSBHAUB3RA/dp/B001AR4NC8/ - These cables aren't particularly good for charging with a standard charger because they're thin - but that same "problem" makes them good for connecting to a phone in a car mount. (I cannot find heavier-gauge cables with a right angle connector). If you use a standard charger with them, you'll find your battery draining with Google Maps Navigation. With a QC2.0 car charger - the battery will actually charge while running Navigation.
I've confirmed QC2.0 functionality with a Tenergy wall charger, a Powermod car charger, and an Aukey external pack. The Tenergy wall charger is nice in that it has an indicator light - blue if in "standard" 5v mode, green if in 9v or 12v QC2.0 modes. Sony's stock chargers are NOT QC2.0 capable.

I find it interesting that you say this, because even with the phone left untouched I can't even get 1.0A charging with the stock charger and stock usb cable. As I have shown in my post before, I get a 0.8 to 0.9A charging, and yes, the screen is off. I have not touched my phone during this time at all. What can I conclude from that? Isn't the stock usb cable good enough?
Moreover, if this limit is set the by Z3 Kernel, it is possible to edit in the stock kernel, isn't it?
Regards.

In my case, I was using a Samsung tablet charger. These actually increase their voltage slightly under load to compensate for cable losses. I forget what Sony's stock charger is rated - but if you're only seeing 0.8-0.9A, then it might be on the weak side (just like the 2012 Nexus 7 had a weak charger). I pretty much exclusively use Anker multiport power supplies and either Monoprice or Anker heavy-gauge (24AWG for Monoprice, supposedly 21 for the Anker, lower is thicker/better here) cables.
A QC2.0 charger makes the cable selection FAR less important - transferring a given wattage requires less current at 9V than at 5V, which leads to less resistive losses in the cable. Same principle as why power grids use hundreds of kilovolts for long-haul transmission lines.
Yes the kernel could be altered, but since the battery is nonreplaceable, few responsible developers are going to do it. Heck, sony AOSP currently disables the HVDCP service due to paranoia about ensuring that ALL battery management protection mechanisms are in place before turning it on in AOSP. (I am fairly certain they ARE all there, but I want to do some more digging.)
HVDCP?what is that?so if the kernel is altered then quick charge 2.0 can be used?so now my z3 d6653 can only charge a maximum current of 1.5 A?

HVDCP - High Voltage Dedicated Charging Port - I think Qualcomm is actually attempting to get QC2.0 standardized (they're already licensing it to non-QCOM OEMs - the Galaxy S6 supports it, as does NVidia's SHIELD Tablet, NV doesn't market the capability AT ALL but it's there!), so there are lots of references to naming conventions consistent with the USB Battery Charging Standard
DCP - Dedicated Charging Port (dumb wall charger)
SDP - Standard Downstream Port (PC port, limited to 500 mA)
CDP - Charging Downstream Port (PC port, allows for higher current) - Android device support for CDP detection is pretty rare, lots of kernel developers will risk damaging SDPs by simply forcing CDP behavior from an SDP
Even without kernel alterations, Quick Charge 2.0 is used - Quick Charge 2.0 is defined as delivering 9v or 12v from the wall to the device in order to deliver more power. It's up to the OEM whether to dump more of that into the battery, or simply to use it to allow for higher total system power. Without QC2.0, the Z3 can only charge at full rate in the absolute best of circumstances (screen turned off, even then it doesn't always reach 1.5A) - with QC2.0, the Z3 can charge at full speed even with the screen on.

Yes, it will charge faster.
How much faster depends on what you're doing. If the device's screen is off and it's idle, only a little bit faster.
If you're running Google Maps Navigation in a car, the difference will be massive. As in "charging at a decent rate vs. discharging despite being connected to a power supply".
It will charge in around 130 minutes with QC2.0, and around 210 minutes with the stock charger (EP880).
At least that's how it works for me.

I'm on stock 6 0.1 or 6.1 (whatever the latest is)
And I'm looking to improve battery life. I already have wifi off. Use Ethernet adapter, and charge it via a USB hub. But it's charging very slowly.
Screen brightness at max cuz I can't go with lower lol.
So yeah I want to do everything I can.
so far the marshmellow roms I have seen are:
Kali Nethunter (k1 compatible)
Dirty Unicorn
Bliss
Resurrection Remix ROM
For the other roms I could not find if they are K1 compatible. so I would be reluctant to try them.
all roms of orig shield tablet are compatible to shield k1 , as for battery life i get around 5-6hrs of screen on time with stock and BitO kernel. I use greenify to supress useless apps and macrodroid to automate location ,wifi and battery saver settings.
Which charger are you using? i use anker qc2.0 compatible charger and my charging speeds are fairly good (around 4hrs i guess but i never observed time precisely).
I also use cm13 (multirom) as my secondary rom.

I'm using a Samsung charger lol :
Input 100-240V 0.35A
Output 5V 2.0A
But today I bought a Bandbridge BXP410EC - Rev 01-08 Size 455W-SC193 USB hub and it has it's separate charger.
The hub itself reads 5V DC 2.5 A
The adapter reads Input 100-240V 0.5 A
Output 5V 2.6A Max 13 W
BitO kernel is not same as entire custom rom?
Do you know, if there is a difference in battery time when using a different rom/kernel.
I am reluctant to do a wipe of my tablet. don't want to lose my apps and go to the hassle.
I will only do it if I know I can get advantage.
The maximum power you get on an usb hub is 0.5A. The shield tablet needs 2.0A to charge at full speed. Charging on an 2.0A charger (not hub) should take around 3 hours at maximum.

BitO kernel is not a rom , when you install bitO kernel data wipe is needed. Only cache wiping is recommended. If your data is important then take a backup in TWRP recovery first and try these. So if anything goes wrong while trying kernels/roms you can revert back to your previous state as if nothing happened.
and for charger i dont know about what you've bought but i am using this one http://www.amazon.com/AUKEY-Dual-Travel-Charger-Adapter/dp/B00Q873I3K and it provides 2.4A
Hi everyone. Today I was reading about battery charging because I play with kernel modifications (faster battery charging), for example, i have a Lenovo A6020, wich have an SM5414 charger (can be powered with 5V up to 2,5A), but my battery is 2750mA/h. So... This device support high current battery charging (i think is compatible with quick charge 2.0 technollogy) . But, the point is: Is good for battery (can be risk?) with high current? What is a acceptable current for charging these batteries? And for example, in HVDCP (QC 3.0), With 5 / 9 and 12V, this current incrases a lot? All these circuits have buck converters to supply a stable voltage (4.4V) and a variable (High current, 1,5A~4A in some models). In my kernel mods i also used arround 2,5A at buck output (charging current) and measured with ammeter in USB cable 2,05A (programmed at kernel drivers). Mi xiaomi redmi 4x has a SM1351 charger and support HVDCP with 5, 9 and 12V all with 2A maximum.
Hello everyone!
I recently purchased a Mi note 5 pro that comes with a 5V,2A charger out of the box.
While using it I realised the phone started warming up while charging with it- The phone reached a temperature of 42 deg C (well, the device got significantly warm).
Concerned, I tried out an old Samsung charger (5V,0.7A) with my Mi device and realised the charging temperature was much less (35 deg C) (here, the device remained cool).
Well, I wanted to know:
- Is it safe to charge the Li-ion battery at low charging currents (voltage is constant at 5V) ?
- Is it okay to use a different manufacturer's charger with my device (even if the charger is a genuine one)?
Also,
-I don't have a problem with longer charging times
-I frequently keep the device plugged in and maintain the charge between 20% and 80% (and full charge cycle once or twice a month)
-I am a heavy user but I avoid using the device while it is plugged in
-AccuBattery was the app I used for battery measurements
In the end I'm just curious to know how to prolong the battery life of my device and I'd really appreciate the help.
Thank you
1. Yes it's absolutely fine to charge at a low charging current. It is in fact better for the battery to charge it at a low current.
2. Yes, it's also absolutely fine to charge with different chargers, the quality of the charger is what is important.
