[Galaxy Note 3 Accessories] Rbentley100:
Hi,

I got my note 3 the other week and just got the samsung smart dock today.

The note 3 is brilliant so far and as far Im aware it is MHL 2.0 compliant.

I plugged in the smart dock last night into my reciever and I got the screen mirrored onto my tv however I am getting no sound at all

However If I plug the hdmi cable into my TVs hdmi input I get both video and sound (the problem being that my tv has an issue with DT, DTS HD etc. All I can do is pass a dolby digital signal to my reciever via optical cable.

The reciever works perfectly fine for HDMI out from my htpc at the mometn (and to confirm it wasnt the settings on the reciever I ever plugged the dock into the same input as the HTPC (replaced it temporarily) Still no sound.

Does anyone have any idea why the audio works through my tv and not the reciever? (my reciever is a denon 1910, my tv is a Samsung B650) As far Im aware audio over hdmi is a standard and if anything the recoever should be able to work better as it can decode more formats.

The other thing I noticed was that I am getting 1080p at 30hz, does this make the smart dock only MHL1.0 compliant?

Any help would be greatly appreciated.

Thanks in advance
[Galaxy Note 3 Accessories] HOGWILD:
go to settings / accessory and then either click or unclick the audio out mode. then try.
[Galaxy Note 3 Accessories] Rbentley100:
Thanks for the fast responce. This does tie into what I have read elsewhere unfortunately it didnt seem to have an impact for me :( I have tried both ticked and unticked. my reciever still gets no audio.

(My TV only recieves audio if it is unticked)
[Galaxy Note 3 Accessories] RavenY2K3:
In the same place there is an option for HDMI surround or stereo, have you tried changing that around?
[Galaxy Note 3 Accessories] Rbentley100:
Unfortunately yes. Maybe I havent tried all combinations of the 2 options though.

I think I tried unticked stereo, surround unticked and surround ticked. I can try messing with these again tonight to see if it has any affect.

Is there any reason these settings would need changing for plugging into a reciever vs plugging into my tv directly? I would have thought if it works for one it should work for the other.

Thanks again for the help
[Galaxy Note 3 Accessories] Rbentley100:
no luck, tried all combinations of both of those settings. no sound at all coming out of my reciever :(
[Galaxy Note 3 Accessories] vikramdhani:
Not trying to high jack your thread but what smart dock you are talking about ? it is the same that is available for note ?
[Galaxy Note 3 Accessories] Rbentley100:
Sorry, thought I had already replied to this. Yes, this is just the note 2 dock. as I assumed it is just using th MHL standard I believe the note 3 should be just as compatable as the Note 2
[Galaxy Note 3 Accessories] ksy77:
Note 3 smart dock

The note 2 smart dock worked with my note 3 with sound? See here:

youtube.com/watch?v=lWN43pnkg0s

This is a long shot but on your note 3, go to settings>general>accessory>check off "Audio output mode" (Use external speakers when device is docked).

See if that works?

Also, I know this is silly but try unlpugging the smart dock power source and then replugging it in the back of the dock. Someone had issues where reconnecting the power source on back of the dock helped resolve some recognition issue with the usb. Long shot but worth a try.

Hi everyone I just installed nfs most wanted on my s2 9105 version and download it via wireless connection but it seems the game freezes a lot in downloading the graphics but if it succeed to load them it wont freeze during race does anyone knows how to solve it ?? please help i like this gae so much !!
[Samsung Galaxy S II Plus] nanoteam:
it's normal ... it loads the texture and generating 3d graphic to the ram it will freeze all most games are like this ..
[Samsung Galaxy S II Plus] John michell:
the problem is my friend the game completely freeze on loading screen with no more progress ..
[Samsung Galaxy S II Plus] celticbg:
I confirm that the game is ****. I bought it from samsung apps and it freezes. On start screen or while playing it. The game is full of bugs and freezes. Not worth buying it.

Don't worry, your phone is fine. The game sucks - fact!
[Samsung Galaxy S II Plus] John michell:
Glad to hear that bro i thought the problem is with the phone but i tried the game on s3 also the same result ..
[Samsung Galaxy S II Plus] celticbg:
No problems ;) I was disappointed too because it was looking like a great game.

[Sony Xperia Z Ultra] Purple_Clouded:
When I use the Walkman app the volume for my headphones, or any type of ear/headphones is just way too low, even when set to max. It was working great before I had the phone dipped in water (freshwater/cold/clean/from a sink lol) just to clean it. NO water got inside the phone and I can confirm this and HAVE confirmed this throughout many people and tests. Now the volume of my headset when PUT TO MAX on YouTube/Walkman/Anything that plays sounds is just way too low than when it was before. I KNOW for a FACT that there is something wrong, and I would rather not option to factory reset, although I will if necessary.

Also, I'm not able to use VRoot or any other method of rooting my XZU. It will successfully install on the phone but when I try to install SuperSU or Superuser it will NOT install to my device and restarts the phone (takes a while btw) with the app gone, asking me to reinstall it again if it didn't properly work. This happens over and over even after installing and reinstalling VRoot.

I have a C6833 with no mods whatsoever, running on T-Mobile's 4G LTE, apps that are installed are the usual Twitter/FB/IG/Snapchat/Tumblr so on.

Please help me out.. I would extremely appreciate it as I'd like to install some custom roms and kernel tweaks as well.

Thanks in advance!!!
[Sony Xperia Z Ultra] SUPERUSER:
hmm I dunno about the phone.. but the headset, have you tried to pick out the foam blocking the way to the element? I always pick that out before I start using them as when overtime when having in-ears in the ears the wax dries on the surface which blocks the air and dampen the sound.
[Sony Xperia Z Ultra] bASKOU:
So, about the headphone, for me even after cleaning it no problem, but did you check if the jack is well dry? As it is not cover water can go in and so mess with the contact between the jack and the phone.

For rooting process it is really troubling, but do you let your phone plugged to the PC while installing SuperSU? Do you follow the process:

Root with vroot (phone reboot auto)

Install SuperSU, open it, update binary normal (not cwm/twrp), grant root access.

Plug the phone and unroot with vroot (phone reboot auto)

Install SuperSU to /system/app (SuperSU disappear need to reboot for see it again)

Work flawlessly for me on .532 and for other people with a C6833.

Look at this thread http://xdaforums.com/showthread.php?t=2446502 you have picture and YouTube tuto on how to root. And also all you need to do before be able to flash a Rom. But flashing a rom mean do a factory reset as well.

[Nexus 7 (2013) Original Android Development] tni.andro:
I have developed a kernel patch that allows controlling the charge voltage of the battery. Lowering the charge voltage will typically increase battery cycle life by 2x for 0.1V and potentially much more at high temperatures. The default charge voltage is 4.3V, so with 4.2V you can expect 2x the battery life; with 4.1V 4x the battery life (the battery won't be fully charged).

The patch adds a new sysfs control: '/sys/devices/i2c-0/0-006a/float_voltage'. The setting is in milli-Volt; 3800mV - 4300mV is allowed. The charger supports 20mV increments.

For setting the charge voltage permanently, you can add something like:

echo 4100 > /sys/devices/i2c-0/0-006a/float_voltage

to an init script.

For my N7:

4.0V -> 73% charge

4.1V -> 83% charge

4.2V -> 93% charge

4.3V -> 100% charge

(The patch is against the stock kernel.)

The patch is included in the ElementalX kernel:

and the Glitch kernel:

[Nexus 7 (2013) Original Android Development] adichandra:
anyone care to try first? is it any different than undervolting with custom kernel?
[Nexus 7 (2013) Original Android Development] tni.andro:
This is very different. It isn't supposed to increase battery runtime, it's supposed to decrease it. ;)

It allows allows to not completely charge the battery. In return, the battery won't deteriorate as quickly. Making up numbers here: if the battery would normally survive 300 charge cycles (charged to 4.3V); if you only charge to 4.2V (or about 93% capacity), the battery would last for 600 charge cycles before it's dead.
[Nexus 7 (2013) Original Android Development] adichandra:
ah i thought this tweak was about to give double battery life in one single charge. might be usef for others but not me though since i never use a gadget more than 18 months. thanks
[Nexus 7 (2013) Original Android Development] tiny4579:
No it extends your battery life as in the longevity. The battery life that we usually think of is how long the battery will last on a charge like you were thinking. That's not what this mod is for. Such a mod that you were hoping for doesn't exist.
[Nexus 7 (2013) Original Android Development] teh roxxorz:
Oh how they can wish though. Though still good work regardless, and very useful.
[Nexus 7 (2013) Original Android Development] croach246:
Anyone know the actual estimate for the amount of charge cycles the battery can handle before giving up the ghost?

I tend to agree with adichandra.. In today's consumer market, most gadjets are usually obsolete after 18 months..
[Nexus 7 (2013) Original Android Development] OJ in Compton:
So charge cycles are extended by never allowing the battery to charge to 100%? Sounds similar to a feature on my thinkpad laptop that let's you set the charge and discharge thresholds.

Thank you for posting this!
[Nexus 7 (2013) Original Android Development] tni.andro:
Yes. Same idea. Some Samsung laptops have this as well.
[Nexus 7 (2013) Original Android Development] marcus6999:
How can we apply this patch? Sorry for such a noob question...
[Nexus 7 (2013) Original Android Development] tni.andro:
If you are not building your own kernel, there will hopefully be a few kernels in this section that will include this.

If you are building your own kernel, you can take the posted 'smb345-charger.c' and replace 'drivers/power/smb345-charger.c' in your kernel tree. It's based on the stock kernel.
[Nexus 7 (2013) Original Android Development] Crwolv:
Most kernels on all my phones have ability to set precisely the % you want battery charged up too. Haven't seen it for flo/razor

Sent from Pimped N7 (2013) XDA PREMIUM
[Nexus 7 (2013) Original Android Development] CTCaer:
Hmm that's a good suggestion. Truly to increase the battery charge cycle life by almost 2x you just have to charge it until 90%.

So basically you don't charge it to max voltage and you don't let the charger begin the high voltage stabilization.

So with normally (good Lithium batteries these days) 500 charge cycles you go for 1000 and so on.

I was searching for something like that, because it's a tablet that can last through many years.

I think it's a great feature and all kernels should implement and have it at stock. And let the user decide and choose voltage with an easy script if he wants it.

I'm going to add this in the next update to ElementalX
[Nexus 7 (2013) Original Android Development] tni.andro:
There is no good reason to use battery percentage to terminate the charge, instead of using a lower charger float voltage. Likely the only reason a percentage cutoff was used in other cases is that the charger chip didn't support setting the voltage.

The voltage setting is also much more predictable - the battery gauge can be quite unreliable in terms of charge estimate and easily jump 10% when it recalibrates itself.
[Nexus 7 (2013) Original Android Development] neotekz:
Can anyone post the source of info for 2x battery cycle if only charge up to 4.2v? I read that not charging lithiums to full charge can help extended life but never seen anyone give estimates like 2x at 4.2v and 4x for 4.1v. Estimates seem a bit high to me. I agree with others here that this tablet can last a few years if the battery holds up so I was planning on replacing the battery after a year or two but if lowering the battery voltage really works this well then I will try it. There is a pretty big downside of having almost 10% less battery life all the time.

[Nexus 7 (2013) Original Android Development] TDO:
Of course there is. The last 10% to 20% are causing the most aging of a lithium ion battery.

If you really want to prolonge the live of your battery charge it only up to 80%.

There is no real reason to limit the voltage as the stock hardware and drivers handles this already really good by adopting the charging voltage dynamically.
[Nexus 7 (2013) Original Android Development] CTCaer:
There's no reason to change charger's voltage. The only thing there's meaning in changing in the charger side is output current.

For example with the size of Nexus battery you can use a 1A one or 800mA. It will charge slow but you can maintain some more charge cycles.

Still the most important is to not let the battery reach it's maximum voltage (100%) and let the charger do it's voltage stabilization.

As also said from others before that's what takes the battery charge life away.

The best for good juice and year protection is 90%.

The best for year extension and low juice is 60%.

And of course, when you really need 100% juice (trip, flight, beach, whatever) you just charge it full and don't care for some cycles.

Good batteries have -+500 Full charge cycles. So almost one and a half year if you go from 100->0->100 everyday, before the capacity (mAh) of battery drops.
[Nexus 7 (2013) Original Android Development] tni.andro:
That's correct.

That's exactly what lowering the charger float voltage can do. The original post has numbers for different voltages. E.g. with a 4.1V charger float voltage, the charger will stop charging at 83% charge.

The stock driver sets the charger float voltage to 4.3V. Given that there is current limiting (1200mA input current limit), the voltage will be lower initially, but the voltage regulation is 4.3V once the current is low enough.

Like I mentioned, using the battery percentage as cutoff isn't great, since the battery gauge can be pretty inaccurate (can be off by >10%). Setting the float voltage lower results in the same charge cuttoff every time, even if the battery gauge makes an inaccurate estimate.
[Nexus 7 (2013) Original Android Development] tni.andro:
No. In the initial charging phase, while the charger is in current limit mode, the float voltage doesn't matter. However, in the second charge phase, when the battery has reached the float voltage it does. The lower float voltage results in a lower charge current in the second charge phase and earlier charge termination.
[Nexus 7 (2013) Original Android Development] tni.andro:
Those 500 cycles are generally manufacturer specs in very battery-friendly conditions (low temperature, low charge/discharge current). For heavy users, there are plenty of phone batteries that die within a year.

What quality the N7 battery is - who knows. But IME, Asus isn't good with battery life time. Regularly used in high temperatures (e.g. in a car) chances are very high that a substantial number of batteries will die within a year.
[Nexus 7 (2013) Original Android Development] CTCaer:
I also understand about the %. And I want to clarify that when I'm talking about percentage I mean the correspondence voltage output of battery.

Which normally can be calculated when the battery is young with little charge cycles.

And of course you are right about inaccuracy and that's when there's fast charging, big loads, battery age and more.

But still doesn't matter, the important is the battery max voltage, every user can use his own charge voltage <= 4.3V.

We just provide some starting points.

For example 60% (with screen on and low brightness light) for me is ~3900mV. I'm saying what load it has because when you draw current from a battery, the voltage changes. Example of voltage variation without capacity (%, mAh) drop: Bright screen: 3900mV, Screen off: 3940mV.

So basically a value between 4000mV and 4100mV will be enough to extend the charge cycles by a lot.

You can even use 3900-3950mV when you use it at home, and like I said charge it fully when you planned a trip, meeting or what you see you gonna need more juice for extended period without charger.

So for script changer I think these will be good (max 4.3V):

Battery Age Extention:

1. Biggest Age (Max 60%): 3900mV

2. Big Age (?%): ?mV

3. Big juice, Double Age (90%): ?mV

4. Max juice (100%): 4300mV

I will fill in the volts when possible. I have Nexus 7 2013 for 3 weeks now (voltage is now more stabilized with many charges), and also it has no battery aging so the numbers with zero cpu/screen load will have good accuracy.

---EDIT---

Yeah battery charge cycles life varies a lot with usage/condition/temperature :/

Hopefully for me even the almost 2 years phone I have, have only dropped 140mAh max capacity.

Anyway whatever the usage, it's a nice feature to have.

Also when I'm saying the chargers voltage, I really mean the charger output voltage. Not the float voltage, which basically is the battery's current ouput voltage
[Nexus 7 (2013) Original Android Development] jwong.hhf:
Great feature that every kernel should have!:good:

For now Ionly manually stop charging when the percentage hits 95%...
[Nexus 7 (2013) Original Android Development] marcus6999:
I have used two kernels that used your script, with the 4200 option, but the problem comes when I reboot: This voltage, in the float_voltage file, returns to the stockish 4300, is this a bug? :confused:
[Nexus 7 (2013) Original Android Development] tni.andro:
If the file doesn't say 4200, the setting wasn't applied.

If you are using ElementalX, there are issues with the init.d scripts and/or config file not always getting written properly by the Aroma installer.

/system/etc/elementalx.conf

should have an entry 'BLE=4200'.

/system/etc/init.d/99elementalx

should be there and not be empty.
[Nexus 7 (2013) Original Android Development] marcus6999:
You were right, but even though I introduce them manually the thing doesn't change, the same float voltage every time I reboot, 4300mV.

Maybe if you could tell me what I must introduce in /system/etc/init.d/99elementalx it would work.
[Nexus 7 (2013) Original Android Development] tni.andro:
If /system/etc/init.d/99elementalx was properly installed, it should have a section:

#battery life extender

if [ "`grep BLE=4200 $ELEX_CONF`" ]; then

echo 4200 > /sys/devices/i2c-0/0-006a/float_voltage;

echo Lower charge voltage to 4.2V >> $ELEX_LOGFILE;

elif [ "`grep BLE=4100 $ELEX_CONF`" ]; then

echo 4100 > /sys/devices/i2c-0/0-006a/float_voltage;

echo Lower charge voltage to 4.1V >> $ELEX_LOGFILE;

elif [ "`grep BLE=4000 $ELEX_CONF`" ]; then

echo 4000 > /sys/devices/i2c-0/0-006a/float_voltage;

echo Lower charge voltage to 4.0V >> $ELEX_LOGFILE;

else

echo fsync disabled >> $ELEX_LOGFILE;

4.4 and how

Love using this from my previous set-ups as I am very careful with my tablet (its the first one I ever bought with my own money hahaha). How do I apply this coming from a 4.4 stock rooted N7? Thanks in advance
[Nexus 7 (2013) Original Android Development] Dollyllama:
First, thank you for posting this and thank you for the literature to back up your reasoning.

I use my phone as a wifi hotspot all day long while I'm at work. If I were to modify your script/incorporate it into a kernel that I modify for my phone (LG G2), could I theoretically leave the phone on the charger all day long, in turn reducing the charging voltage, limiting the charge to 83% and prolonging the battery longevity?

If your phone were an N7, yes.

The smb345 charger driver (and thus this patch) is specific for the 2013 N7 and won't work with any other device (the charger driver is partially controlled by the battery gauge driver). The driver wouldn't even work on another device with the same smb345 charger chip.
[Nexus 7 (2013) Original Android Development] Gizoman:
Sorry if was not clear, but let me ask one more time in another words.

Will my N7 blow up/burn down the house/grow a tumor if i charge it over night on Qi wireless charger with your 4.2V (94% charge max.) patch in Glitch kernel? Does the N7 send "stop charging" signal to Qi charger when it reaches 4.2V? Sorry for my low IQ.

:angel:
[Nexus 7 (2013) Original Android Development] tni.andro:
It's normal that it still says charging. The charger chip will terminate charging when the current drops low enough. (Qi charging doesn't make a difference - it's just another power source.)

You can verify that by either looking at the kernel log (run dmesg in a terminal), which will have entries like

<5>[80688.514526] bq27541_get_psp current_now = 0 mA

the current_now value is the current flowing into or out of the battery as measured by the battery gauge chip.

You also look at the sysfs file (e.g. with ES Explorer):

/sys/class/power_supply/battery/current_now

which will contain the current value.
[Nexus 7 (2013) Original Android Development] Gizoman:
I have done the test and when the battery reaches its 4.2V mark it starts to show negative current in /current_now file. Thanks for the tip! :highfive:

Now I can sleep without an extinguisher under the pillow, hehe.
