Hi my friends, i m sorry for my bad english
i have Galaxy S4 i9500 phone
2 hours charging my phone,
I did install the ROM and is now 3-hour charge, (2 hours to 3 hours)
I changed the battery voltage with synapse with me,
Battery Charger My values like now:
Referance: 1200 mA
Maximum: 1440 mA
Average: 1800 mA
I wonder if I did the right thing? What is wrong if the correct values?
revenue loss to my phone? Are you the author of normal value?

I remember reading a thread labeled [THINK TANK] to discuss how the vibrant dies around 3400 to 3600 mV, when a full charge is at 3900 mV. I searched for over an hour and could not find it.
This is the discussion, I know it's not healthy for Li-ion batteries to discharge fully, however they were talking about a kernel or rom or something that would allow the battery to discharge to about 3200 or 3000 mV which seems to still be a healthy range for Li-ion discharge and would seem to nearly double uptime.
3300 mV is the nominal voltage. It could be modified to shut off at this, but the battery life duration is still unknown.
Edit: full charge is 4250 mV
I think I remember Eugene saying voltage is controlled by the kernel but couldn't be edited without the source. Now that the source is availible hopefully we will see something soon. Batteries are so cheap I'm sure most of us wouldn't mind trading battery life for lifespan.
can some one please confirm the condition of my battery.... it charges with 800 mA till 80 percent then charging falls to 200 mA and it takes 1 hour to charge from 80 to 100 percent.... im attaching my battery monitor txt file

I can not confirm.
At me from 90 % to 100 % pressure of a charge to 200 falls, but hour is charged not, 15 it is no more minutes.
Can try to calibrate to you the battery.

This is the charging characteristic of lithium ion battery. Current will be lower as it is near to full capacity. You can Google for it.
I fix this problem by drain batt to 10% and charge to Full by Docking. Now it come in to normal (Stand by around 2 days.)
Hi....
My problem happened suddenly ... i found my phone charges at 1900mA .. i tried to change the charger but even the 0.7ma output charger gives me 1900mA ... i use the original charger and battery and i changed the charger and the battery with now ones but the sames... when i remove the battery for 10 mints .. it charges at 1200mA for short time maybe 5 mints then goes 1900mA and it chrges the battery in less than 40 mints but -_- it drains very quickly ..... what are your opinions ? What is the problem ? How can i overcome it ?
..
Thanx all ..
Any answers! !!

So your problem is high battery drain? SGS4 charger is 2000 mA, so I think 1900 mA charging current is normal - but 700 mA charger should not output 1900 mA - maybe there is some mistake? Have you actually measured the output current of a charger?
How old your battery is and does it have bumps on the sides (needs to be flat sides)? And see battery stats is your phone staying awake while you not using it?

The mobile and the battery are new ... i bought them less than a month ago .. .... i tried 3 batteries from my friends ... all have the same thing.... my ....my one phone just read the 0.7A charger as 1900mA power ....
my battery starts to drain 3 days..... when it 100% and i use *#0228## it get 70% ... then i charge it 100% it isnot draining ...
Have you checked does the battery voltage change, if the battery percentage is not draining`?

How can i check the voltage and wt the optimum must it be?
I tried that code *#0228# which took me to batterystats, so there is battery voltage (mV).
I'm not sure about voltage amount, but try google " li ion battery voltage vs capacity", that seems to give out some info. But as far as I know battery percentage is derived from voltage, so it would be good to confirm that your phone can read battery voltages correctly. Maybe someone else is more specified about batteries, to explain details.

Hello, once I installed latest Cm on my g900f it kept overheating while charging and its values while charging (via Galaxy Charging Current) were stuck to 1800 mAh without scaling to 1200 mAh (with screen on) . The consequence of this is that the phone overheated and it reached 45°C. I tried using other chargers but it didn't work. When I flashed back stock rom its values came back to 1200 mAh. Any suggestions? Thanks
On my Huawei P Smart I tried to install Ampere to check the mA during charging. With the original charger the app marked me max 870 mA. It seemed strange, because the charger is 2A and because with 1000 mA during charging it would take 3 hours to charge the 3000 mAh battery, and the smartphone takes less (not so much less in fact).
Disappointed by the app, I tried to make a partial charge from 24% to 91% (with another non-original 2A charger) in 1h 56m 30s. 67% charge = 2010 mAh in 1,94 hours, so 2010 / 1,94 = 1036 mA during the charge.
I specify that during charging the phone was on (not in use). Do you think that is right? It is not a little slow? Do you have a feedback to give me about?
(Sorry for my English not so good)
