maximum battery voltage when fully charged

in one of the threads i read that if you want to know weather your battery is working on full capacity or not you have to get 4.20 to 4.50 V when fully charged
i have been working on that for a couple of days with different builds
but all i got was a number between 4.150 to 4.18
now the big questions is this
how much you dear friend get when your beloved hd2 is fully charged and the snap dragon inside is angry enough?
just post your voltage that you get also any idea is welcomed

I've read 4.3 is what we're after but never get past 4.197, even after clearing battery stats, doesn't seem to be too much of a problem though!

4.2 is the most I ever got on my phone. I've never wiped the battery stats, too afraid now with magldr's charging problems.
From my understanding of lithium ion batteries, they last longer at less than full charge anyway.

You also need to take tolerance into concideration.
The Voltage sensor probably has a couple of % tolerance which can also be influenced by temperature, humidity etc
So I wouldn't worry, or even compare, if one is stuck at max 4.1 to 4.3 Volts.

Fluctuating Charging Voltage
Nice thread. Guys, I need your reply...
I'm designing a portable 4 Ni-MH powered USB charger for my Xperia X8. The peak summing voltage is 5,9V for zero load.
The question:
1. Is 5,9 V tolerable to be the input voltage?
2. What is definitely the 'legal' input voltage tolerance for the X8?
3. Does any recent handset always have built-in voltage regulator to make sure the battery is charged correctly?
Thanks for sharing...

amyway to. charge faster?

any way to charge the p600 faster?
I believe its the exnoyos octa processor. this is seriously making me consider snapdragon version of note pro 12.2 since it will be usb 3.0, any idea what that model will be. called?
curious, what , if any of p601 or p605 have that snapdragon 800, the quick charge 2.0??
thanks

There are many threads on this but anyhoo.
There is a way to charge P600 in 4hours from 5% to 100%. Put it on charge from 5% to just over 80% and then unplug and plug it straignt back in. Dont know why but it charges slowly from 80% if you dont do this.

Pretty sure the slower "trickle" charge after 80% is to help prolong battery longevity and to prevent overheating. Li-ion/Po cells are very sensitive and dangerous so dropping too much energy in a very fast manner will age the cells faster and also could cause them to overheat and possibly explode

Oh :what:
I guess I wont be doing that again then, thanks for letting us know.

Any difference using/charging battery voltage lower than stock?

I bought Galaxy S5 G900V weeks ago and noticed that the voltage of my stock battery is 3.85V, but it is 3.8V in a 3rd party extended battery I am interesting in. Any difference while using/charging a battery voltage is lower? Thanks.

Same question here

If it's that small difference nothing really. But if its much lower, it just wouldn't charge your device/battery. That's all. What you have to be careful is the higher voltage, your device could be over-voltaged and the battery/device might get damaged. Think of it as eating a half-meal compared to a full meal VS being fully bloated.

[Q] S4 I9505 for N00bs

Hi Guys, ive been part of the HTC One X scene and now i am getting an s4, question is i hate Touchwiz with a passion!! so i want to use an AOSP rom, my question is what is the easiest one to use and are modded kernals a good idea with this phone? regards,

I use Danvdh's GPE ROM. It basically converts your existing S4 into a Google Play Edition S4, but with some subtle enhancements. Being a GPE ROM, it also has the advantage of using Samsung libraries for its hardware, which makes it run more smoothly than the AOSP alternatives that use reverse engineered drivers.

I had been leaning to that Rom, what about kernels any that actually make a noticeable difference? I keep seeing fast charge pop up ?

Use the Googy Max kernel that's included, or use the more up-to-date Hulk kernel variant of Googy Max. Alucard's kernel reportedly has a battery drain issue and the stock kernel introduces random reboots. As for fast charging, I've not gone through every post in that thread so if there is a fast charge option I'm not aware of it.

Is there any idiots guide to do it? Lok

An idiot's guide to install the ROM? Root, install a custom recovery (TWRP recommended here), and install the ROM through recovery. The various kernels and ROM options are all in the zip, as it uses Aroma installer.

Easiest way to root? Still on kitkat if that makes a difference

CF-Autoroot. There should be a thread for it in S4 General.

I actually find the CM12 optimzed builds to be a bit snappier than GPE. But GPE is more stable and bug free. I had several problems with the latest CM12 builds.
You can always change roms afterwards. But I keep coming back to GPE The only downside is that there is no ktoonsez kernel for GPE 5.0.
It's an awesome kernel and the only one, that I know of, to offer GPU Overclocking.
Alucard and Googy-Max kernels are great too.
Fast charge is designed for USB. The USB current is lower than the AC current. This means that the phone takes a lot longer to charge via USB.
Fast charge substitutes AC to USB. Meaning that it will charge via USB with the same current as AC.

I was thinking of the rapid charging devices like the Nexus 6 have, where you get 50% power in roughly a half hour. Glad someone around here can keep me straight.

Well, it was mainly done to increase charging speed via USB, I think.
But you can also increase the current on AC charger. Which means it charges faster, similar to what you said.
I don't know what the default is on touchwiz stock kernel, but Googy set it at 1450 mAh for AC.
Alucard kernel comes with 1900 mAh for AC. Which means it charges relatively faster. Look at it as "Overclocking" your charger
But it may also reduce the battery's life.

Googy and Hulk allow you to set the AC and USB voltages, so I left USB alone but set AC to 1900. Its unlikely that battery life will be adversely affected by ramping up the amperage of the charging circuit, unless the battery gets exceptionally hot (it doesn't) in the process. The stock charger won't be damaged by doing this as the charger is rated for 2A in the first place. Third party chargers, as long as they're rated for 2A, won't be damaged. Smaller chargers will eventually fry.

I leave it at 1450. I'm in no hurry. Especially when I'm gaming

Low charging current on i9505, CM12.1 SABERMOD

So.. my s4 with CM12.1 SABERMOD(oct 15) has low charging current, 760 Ma.
My question is: Can i change it the charging voltage, if the kernel doens't support STweaks to change it from battery AC Charge current setting, like i do from others roms ?
asking in particular @Synergy510

You can change charging voltage but it must be an kernel that's supports changing Voltage for example: alcurd kernel, hulk kernel(an brand new kernel),etc.

Afaik, I didn't include it in my kernel. Was the current always low like this? And have you experienced higher currents on my ROM before? You should also try different combinations of chargers and USB cables to make sure either of those aren't bad.

Sounds like your charger is duff. Too many fakes on eBay I found. Get them from Amazon, fulfilled by Amazon. Also need a decent cable, they can be rubbish on eBay too. I went to JuicEBitz for mine.

Also check phone status, make sure it states AC and not USB

I also think it's the charger.

Real story: i was running prev version of saber (SaberModCM12.1-20151005) + Fly on mode and i had about 1000Ma, then i suggested my friend also with same phone to install saber(SaberModCM12.1-20151015) without Fly on mode, and he had 700Ma, after cause i had some lag cause of Fly on mode, and because i wanted to up my rom to lasted version i installed it (SaberModCM12.1-20151024-jflte-ecb6003d89-GCC4.9) and i had 700Ma too
I also tried another charger, and another outlet, same...
It's somehow annoying because the phone is charging slow, too slow, when i'm using it sometimes it just didn't charge it's go lower ...
