I need an app where i can see what voltage its getting when charging. I think current widget is not working. Also i don't know why my battery did this. Lost 10% in an instant. (check screenshot) No wake locks. I've been using a belkin charger with 5v = 1a output and a generic micro usb.

You could try AndroSensor. It shows all the data from the phone's sensors, including battery temperature and voltage.
As for the 10% drop, did this happen right after you took the phone off charge? I've read a lot about the phone's "trickle charging", where the battery charges to 100%, charging stops. When the battery drops a little it begins charging again to 100% but it won't display this while plugged in.
Depending when you took the phone off charge, you might have caught it after the battery dropped and before it charged back up to 100%.
Hope this helps!

I seem to get a longer battery life (first step down from 100%) if I charge my MDA C4 using the supplied charger as opposed to a charge from a PC using the USB lead.
If I charge using the charger, and just use 2G, I get approx 14 hours before the first drop in the batterymeter. From the PC it happens well before 11 hours.
Is this possible or am I just imagining things?

To get full capacity phone needs 5v 1000mA (= 1A) input, which is the charger outputs. If the PC USB output cannot pump that amount it might last shorter....
a PC's standard USB port only outputs 500mA (0.5A)
i think the supplied charger may be 2A (cant check atm), i know the official HTC Car Charger is 2A.
Cheers,

My original HTC charger (Model: TC P300) outputs 5v 1A
Interesting. I'll check the HTC charger when I get home.
However, Would this not mean that it would just take longer to charge the battery?
(Analagous to having to fill a bucket of water from a 1/2" bore pipe as opposed to a 1" bore pipe).

My original HTC charger is at 5V 2A.
What I did notice is that charging form USB takes much longer than charging off the wall.

It will do, should not effect the overall charge (as long as it is left long enough!)

Correct, actually water analogy is quite often used here
yes i thought that...
phone charge lasted longer with the mains charger than the usb on pc
and usb pc takes ages to charge full
So I guess we'll all be using our wall chargers now? As the charge is faster and some believe better!
Make no sense to me as to why the charge of the PCs USB cable is not as good as from the wall....
However the slow charge time bit of it makes sense
Car Charger
I have huge problem with my car charger. I use Noname USB car charger, that worked perfectly with my Trinity. Now, when i connect my Diamond it sometimes connects and disconnects the device to USB twice in two seconds and so if the battery is low message about battery fklashes in an out. SOmetimes it does not happen and the battery is charging normally. When i start IGO8 while battery is full and Diamond being charged, it sometimes LOOSES power and after couple of hours it gets out of power even when charged. Sometimes it doesnt happen and the device is charging properly, but very very slowly. When i turn device off, it charges normally. I tried two different chargers and get the same results. But none was HTC original.
It's irrelevent how the phone was charged. If the battery is full, then its full ,and it will last the same period of time irrespective of how it was charged.
Charging rates will vary depending on input current, but once the touch sensor light stays on, then the battery is full.
It's seems that when I'm trying to charge my phone with my original charger or another wall charger, the battery doesn't getting charge above random number, the original battery was charged firstly to 70% and than to maximum 55%, I used a solar charger that maybe have output voltage which is higher or that giving more current (which I don't think it is).
I replaced my battery on aother one and now it's seems that I can charge it for more and stuff, but still the original charger can't, and when I'm charging through my PC or a portable charger, it's charging to the maximum.
My micro usb socket in the device is unstable and moving, there is maybe a connection between?
or maybe the chip who responsible to charging got ruined?
edit 22:13:
after more tests I feel the source of the problem is low voltage on the battery, which telling me that the problem is on the connector.
I changed cables, changed chargers, and checked every time the voltage on the battery that the device is sampling.
Try wiping battery stats and if it doesn't work go to your local electronic store and ask them to send your phone to mainentance and replace the connector
I tried wipe, and I bought already a connector and I will replaced by my self.

Sometimes on my phone if i charging to 70% say to me it's full charged, but it's still charging to 100%.
When it comes to 70% or 55% or 60% and the phone says its full, you must load and not unplug charger.
Sorry because my bad English.

it's because you are using stoch GB...
that's not the issue here...
I recently ran an app called Ampere and it says my battery is charging at 3.962 volts at 1030 M.A. Shouldn't it charge around 2000 M.A.? Was wondering if the app is accurate or what are some of your charge rates
Using the Oem charger and cable
My phone charges (while off) from completely dead to fully charged in about an hour and 15 minutes.
Something is wrong with your cable/charger. The official fast charger will quickly charge to about 85% then trickle charge afterwards to 100%

The maximum amperage is determined by which charger you are using, what charging mode you are in, and how full the battery is.
If you are using the Note 4 OEM charger with fast charge capability, take a close look at it. You'll find that in fast charge mode, the maximum amperage is 1.67 A, not 2 A. So, 2 A isn't even possible in a properly functioning OEM charger in fast charge mode.
You will also see that, with fast charge mode turned off, the maximum amperage is 2.0.
Confused? Many are, because we have become used to the notion that, in order to increase charging speed, the amperage needs to be increased. And that is true, so long as the voltage remains the same.
But, when you look closely at the OEM charger, you'll notice that in fast mode, the voltage is 9 V. In regular charge mode, it is 5 V. So, the charger achieves faster charging by increasing voltage, not amperage. Why does this work?
Math.
Power (in watts) = Amperage x Voltage.
In regular charge mode, 5V x 2A = 10 watts of power to the battery. Not bad.
But, in fast charge mode, it's 9V x 1.67A = 15.03 watts, a 50% increase in power to the battery.
Why your battery is pulling 1.03A @ 3.962V is not really clear without more information. As mentioned previously, there are various reasons for your scenario, but in no case can you achieve 2A input to the phone when in fast charge mode.
Try discharging your battery to, say, 20%. Then, look at your numbers again. You'll discover that, as the battery's charge increases, the amperage will decrease. 4V and a little over 1A is what I get when my battery is about 75% full, and it decreases rapidly from there.
I updated OTA to Pie last week, since then it seems my charging speeds have got much slower, taking maybe twice or three times as long. Fast charge is enabled in my settings.
This is on all my chargers, wireless, wired and car charger. Anyone else had this problem?
Unusual for a software update to cause that, does the phone actually report that it's Fast charging?
Edit: Download Ampere and measure the charging speed. Mine reaches 2540 - 2640 mA at 70% charge on a QC3.0 charger for reference.
Try wiping the Cache Parition in Recovery Mode. If that doesn't help, try using a different cable and charger,
Occasionally unplug your charger, disable fast charge.
Plug in charger should show lower charge rate maybe 1100 mA to 1800 mA
Then disconnect charger, re enable fast charge, plug in charger,
Should show 2800 mA approximately

I am never getting more than 1200mA (according to Ampere app). Not with samsung cable, not generic cable nor wireless. Most of the time not more than 500 or 600.
Of course, I cannot compare to what I was getting before Pie update because I never measured the charge then.

I haven't used Ampere app,
My figures came from

Although I would expect very similar figures if accurate
Hi, so I'm having problems with my phones battery when charging. The phone charges to 100% in like 20 minutes, but when I disconnect it, the percentage drops to the actual percentage, i.e. 40%. This happens both with the phone turned on and with the phone turned off. And its easier to notice this when using the turbo charger.
I decided to check the charger output with Ampere and it tells me every charger I plug in delivers 5 Amps, which is impossible, as the Turbo charger has a max of 3 Amps and the other chargers I used where lower than 1 Amp.
If it helps, I'm on Stock Oreo, not rooted, and locked bootloader.
Is there any solution to this? I tried completely draining the battery and charging it fully, and it still happens.
