Battery voltage when fully charged

Hey guys,
can you post what voltage you have, when you fully charged your sgs2?
my value is 4,145V i'm just curious if thats the value i should have when fully charged, or if i should calibrate my battery (i switched some roms)
thx

I've got 4125-4135mV

ive got 4215mV hehe, healthy battery

The same at my cell.
Sent from my GT-I9100 using XDA Premium App

last time i calibrated the battery i reached 4,205 , that is my personal record. But this value is not very significative because it depens from the corrent usage of the phone. Screen on + cpu running a little bit can decrease voltade showed by 0,1 volt. And i also noticed that the charging process is strange. I assembled a little photovoltaic power station and i know the charging process of lead acid batteries. Because they are composed by 6 elements connected in series, at the end of the charging process the charger need to provide for a short time a voltage 1 volt higher than the normal to equalize the cells. The behavior of the Galaxy s2 charger is similar. The top voltage is reached for a few minues then it decrease to a float level. Very strange thing because the battery is a SINGLE cell and don't need the equalization charge like lead acid batteries.
Probably i just have to study much and play less with my galaxy

Roughly the same.

this time i have 2,204V right after reaching 100%
i guess it varies a lil' more than on my hd2 (i had always the same value there)
EDIT:
obviously i mean 4,204V haha

4,152 V most of the time. Didn't notice it go higher than that on my phone

Please tell me how often you do the power cycle and how?
Thanks in advance

i power cycle every time, charge it full overnight, use it for two days, then charge it overnight again
rinse and repeat

mine was just at 4195
i left it on charge for about 30mins after it beeped to say it was full and just callobrated it as i have been flashing loads of stuff all day

After three calibrates, I get a max of 4.200v and a min of 3.451v

Mine is 4195 mV..

Mine exactly 4.2V (4200mV)

Mine 4201mV. This is the time to press the "calibrate battery" button. Right at the top.

Z3C Battery Charging Thread

Hiya,
I' hoping this is the right section to post this in.
I don't have my Z3C yet, but I've been searching for information on charging speed, charging current etc. - and there is barely anything to be found. What seems to be consent: A full charge (0-100%) takes about three hours. But then, some people say an almost full charge (0-90%) takes much less, as charging current is greatly reduced for the last 10% to reduce stress on the battery. Sony itself also claims that a small charge (something like 0-10%) should be quite fast as well.
Then there's some speculation about QuickCharge 2.0 being used or not used, that you could use a Motorola 2.0A charger to charge it faster than with the provided 1.5A Sony charger etc., which also brings up the question which resistor values on the D+ and D- wires are necessary to toggle different charging currents. (Or I might be stupid and there's a standard for that by now, which is the same for all Qualcomm devices.)
To cut it short: I'd request those who have a Z3C to post some comments about their charging times, and at best even their charging currents. I used an app called BatteryMonitor on my Desire HD, I'm sure there's others around now that give the same information. If someone could try out different chargers and record charging current over time, maybe even with a pretty graph, it'd surely help all future discussions about chargers, docks, modifications, DIY charging issues etc.
[EDIT] I've created a similar thread over at the Z3 forums, as many things (such as resistor values and charging tactics) should be similar.

With the 1.5A charger it's almost the same speed as other flagships: about 1% per minute or so.
For quick charge, Qualcomm explains it here: https://www.qualcomm.com/news/snapdragon/2014/06/04/quick-charge-20-has-arrived
Because it's more difficult for me to get the Moto Turbo Charger from where I live, I ordered another quick charger on the list and will see how it works.
Hope I will have time to report soon.

Sorry for the delay. It's obvious that QC 2.0 works only when battery is really low. Not sure it's Sony's control thru hardware, or kernel, or charger's control.

Users regarding battery life from Droid Turbo

I've been waiting for my battery to die. This is my normal use. I just do what I normally do.
Streamed music to my car while driving for a while
browsed reddit/xda and other forums a lot... mainly on WiFi.
Had data/wifi disabled when I didn't need it on... really no point. Takes 3 second to enable it again
~50 texts with a few MMS sent. I'm not a popular person
checked voice mail once.
2-3 bars where I live.

Regarding charging with the turbo charger, I started @ 5% left.
4:25pm - 5%
4:35pm - 17%
4:45pm - 30%
4:55pm - 38%
5:05pm - 50%
5:15pm - 62%
5:25pm - 73%
5:35pm - 81%
5:45pm - 82%

Awesome! I got ~53 hours, but never got a screen shot, and never turned off my radios. Are you using Greenify by chance?

Nope. Didn't configure it yet. I wanted to test out everything to see IF i needed to use greenify.

This things a beast no doubt!
This is normal mode with nothing special running to save battery btw

Max I get is 17 hours with 6 in a half to 7 hours battery life.

Nice! Yeah, this thing just goes and goes...took it off charger yesterday and it's still nice and full! :victory:

You've charged the phone to like 80% somewhere in between the discharging, if you look at your graph...

LOL Oh. Yeah your right. Didn't realize that. I have wireless chargers everywhere "even made one that was non-slip for my truck" must have put it on one sometime and forgot. Sorry bout that guys. Didn't mean to post a false reading LOL But still I've seen pretty close to those numbers several times without charging.. Depends on what I've been doing of course.
Btw That was an old screenshot I just had in my gallery from not long after I got the phone.

Ive gotten 34 hours out of it so far im really impressed

I have the moto Maxx, Mexican firmware. I´m from Argentina.
Could you tell me guys the version and the baseband of yours?
Because it seems that the latin america version the battery is barely poor.
Thanks!

Damn... Going beast mode with this battery. Would've gone longer, but gotta use it more tomorrow when I'm out. Ya, I know I only have 4hrs of SOT. Haven't been using much

I assume anyone getting more than 48 hours of battery life is turning off data, or at least disabling updates/background data. Just out of curiosity, do you always keep that turned off, or do you just do that when you're seeing how much you can squeeze out of the battery? In my mind, the big reason to get a device with a big battery is so you don't have to baby the battery like that.

I disable data and auto sync. I've done this for every phone I've ever owned. Not to preserve battery life, but I have no need to have it on 24/7. I turn it on when I need it.

3500MaH Spare BATTERY SPOTTED in the WILD!

Hi Guys,
Did anyone come across this battery? http://www.ebay.com.my/itm/Quality-...850?pt=LH_DefaultDomain_0&hash=item2ee3147afa
its a 3500mah battery.... how would you know if it is not safe to use?

i think this is a fake...
Do not shipping to germany is a indicator that they have big Problem with the german law... think, do not buy

For $10, it will attract some curious people. We will just have to wait and see the review and feedbacks. But when demand goes up, price goes up.

Then the phone will light on fire as a new and improved feature of the battery ahaha.

who's gonna be the first to try quick charging with that battery?

OK, I've said it in the past... I'll say it again...
Don't you all think that if LG could, they would have implemented a 3,500 mah battery instead of a 3000 mah battery? Especially seeing that it's a minimal cost... If it were truly 3,500 and could withstand the 300-500 recharges as its current battery can hold, then I truly think they would have done it. EVERY review simply states "it's big, but not the biggest in the new flagships" or something of the sort... LG could have had it says "bigger than any other flagship out there!"
This is a total fake. If it's real, that charge won't last more than 20-30 charges, tops, at 3,500 mah.

Actually I have seen manufacturers shy away from bigger batteries to save a few $ (even if it isn't that much). But yeah, this think is probably 2900-3050 mah. I have had multiple Chinese knock offs and the usually work but at best they match the original battery unless they are massive (like my G3 6500 Mah). Only way to know is to try it out and if it sucks get your money back and let everyone know. You'll only be out a few bucks and you might have a battery just as good as the original. My 2 cents

Battery life is fine on this phone...

I have had multiple Chinese batteries, and while they last a while for the first few charges, after that, it's all downhill. They aren't as reliable - at least not these no-name brands. I'd stick with Mugen, they make very good batteries! But hey, at least at that price you can get a battery that you can keep in your bag or something as an emergency. I didn't say it wouldn't work! I just said that the capacity of 3500 probably isn't true.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Redmi Note 8 Pro can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Can anybody please confirm that the phone does support the QC 4+ and not only QC 3.0 by testing charge with different chargers ?

it took less than an hour for me from something below 30% to 99%.
edit: i can provide a gsam battery image if you like to.

I know..but his is how it is..

Note 8 pro does supports 18W fast charger. The charging speed is pretty good for me.

https://www.xda-developers.com/redmi-note-8-pro-teardown-confirms-quick-charge-3-0-support/

I did a test with my device. So at 4% battery, I put it in airplane mode. I used a 30W charger, with a USB Tip C - USB Tip C ports. It took 107 minutes to fully charge. Until 80%, the charging speed was about 13% per 10 minutes. After reaching 80%, the charging speed decreased. The phone reached 81% in 60 minutes. I logged the battery percentage and charging speed percentage every 10 minutes, and I included in a excel graphic. I attach this file. Maybe someone more tech savvy can understand more about the inner mechanism and if it is QC 3.0, 4.0 or whatever.

good

I have a QC4+ charger and a usb power monitor and it only shows QC3.0 on it`s display as the charging method on my 8pro.

I found it funny that using an old 10w charger takes about 15 minutes more to charge my device.
I keep using the old one as it produces less heat, and theoretically should prolong battery life.

Average charging speed with the fast charger provided with it, is 1 point rise per minute.

Which app is preferred to measure the current speed specially in Watts?
