- I used Lg 25w typec to charge v60
- at low percentage, voltage about 3.7 to 4.2 and charging at max ~2.0amp
- higher percentage ( about 60% and above), voltage coming high and current down, 4.3 4.4 4.5v and current about ~0.5amp.
With that reason, my v60 need more than 3hours to full charge.
Can someone check your and compare with me ?

A lot of problems are related to old batteries and when buying new ones you don't know how "new" they are and if the keep their promise.
Worry no longer, with just
mortscript
your device
your battery (or more)
and a spreadsheet (optional)
you can take control of the facts.
The method is descibed in this generic thread.
There you also find the files you need and some apetizers to start.
Method specific discussions go there please!
Please report here in this forum only the results of your measurements in the following format:
Battery type (Producer + Model)
Battery serial number
nominal capacity (in mAh)
your device (it should only be Hurricane here!)
rundown time to 10% capacity with the standardized conditions as descibed in the generic thread
attach the file if you like, but I will not collect them
My current drain measurement for the Hurricane is:
full lit display: 88 mA
dim display: 80 mA
display on, but no backlight: 60 mA (!!)
Let me start with my data:
Code:
Type Battery Serial Battery Capacity [mAh] PBA File 10% time [s]
Samsung-ST26A 5yex149f000725 1050 Hurricane battery-data-1265006544.csv 30202
Sanyo ST26C at3a359w000642 1150 Hurricane battery-data-1264765063.csv 40567
Sanyo ST26C at3a359y001882 1150 Hurricane battery-data-1264865986.csv 42281
Sanyo ST26C at3a35cm000832 1150 Hurricane battery-data-1264926866.csv 40097
Sanyo ST26C at3a35am000417 1150 Hurricane battery-data-1264809237.csv 37302
I must tell you that the Hurricane discharge graph is the worst I have seen for all my measurements. Down to 60% it is roughly linear, but you are cheated as the 60% is in reality much less and the remaining % are eaten very fast!
enjoy!
is there an accurate battery monitoring app that works on the motorola atrix for mA amounts while the battery drains? and the reason I ask if there is one that is accurate, because I have tried using currentwidget, its shows no data for mA, but displays % and the mV. I am in the process of trying battery monitor widget now, but after going on almost to the end of 2 days, I don't believe it's actually accurate. While my phone is not being used and screen off it's lowest standby reading was draining between 15-22mA, losing about 1% of battery every 30mins or so according to the history readout.
im running cm7 beta, faux .2.0 1.3 kernel, radio n_01.77.30p, it's an unlocked motorola atrix from bell that im using on rogers. tegrapart d00
Nothing will give you an "accurate" mA reading unless you can tell the actual mAh capacity of YOUR battery rather than what the battery is rated at. Any app that reports mA is going to be calculating it according to the mAh you say the battery is (again, already inaccurate) and how quickly the battery level percentage is dropping. There is no mA reading that it can just report, its just guessing from given data.
For Battery Monitor Widget though, 15-22mA on standby is weird, I've used that app for months and it has always said 5mA discharge for standby situations. Did you tell the app your battery's mAh rating or is it still whatever the default value is?
its still default i guess, i went to calibration tab, the total max and min are empty
the other fields below say
max: 4205mV min: 3164mV
stored: 1880maH total: 1880maH
measured: pro version only...(that one is obvious...lol)
Your battery should be rated 1930maH unless you are using a non stock battery.

mV != mAh
mV measurement used in the BatteryCalibration app doesn't show your battery capacity. It can only be used as a reference point to when your battery is at 100%. (for 100% it should be around 4200mV).
i realized that my charging time for my phone is quite slow, i would like to increase the voltages or something on my phone to make it faster, does anyone know how?

Been a few threads about this, certain phone chargers will charge your phone quicker but not that much quicker maybe 20/30 mins less, 3 hours is pretty much the norm from 0 to 100%.
but i read about it somewhere that there is a certain setting you can tweak to change the voltages or something to make it charge faster, have you come across that?

I cant say i have mate and id be interested in this myself if it proved to be safe and worked 100%.
Use a kernel that supports increased charging current. Use Siyah kernel for example.
http://forum.xda-developers.com/showthread.php?t=1263838
Then use an init.d script or Voltage Control app from market which has the interface to increase AC,MISC,USB charge current.
Stock values are 650 450 450 [AC:650mA, MISC: 450mA, USB: 450mA]
Try 800 800 450. Charge will be quicker.
note: DO NOT increase USB current beyond 450 and do not increase AC and MISC currents beyond 1000.
Don't screw with it, lithium ion/polymer batteries need proper charging current and voltage, too much will damage or even ignite the battery.
I've been using 800/800/800 ever since siyah put it in his kernel, takes 3 hours to charge an empty battery, 4 hours with stock settings.

thanks man
I was curious if I could remove the charging current rate limit which is 1.55mAh. I would like to charge it at 1.6 ~ 1.7 mAh. Is it possible?
Summer has arrived, the battery temperature has been around 38 °, because of the thermal engine the charging speed is only 2000 + mA, under normal it should be 4000 + mA
version:Android 13 beta 2
Thermal throttling of battery charging is a safety feature. I recommend not trying to override it.

yeah if you disable thermal throttling and let it charge fast the battery will degrade faster because of high heat. If you really want to charge fast while not destroying your battery you could buy one of those Black Shark coolers for around $30, I got the funcooler 2 and my temps went from 38-40 down to around 17° (it'll be even cooler if you leave it running for a while). For a more inexpensive option you could just put an ice bag on the back of the phone
