How should a Note 4 charge in 30 min to 50% (3220 mah) if the charger charges with 1.7A(per hour)?

Sony Xperia Z2
[Xperia Z2 Android Development] Jackos:
Well, I guess the Note 4 uses a different charger.
[Xperia Z2 Android Development] Jackos:
Unfortunately I cannot confirm by hardware that it is charging at 9V, but as I calculated the batt has 29Wh@9V, so according to my research my device was charging ~15W. So this means it's indeed charging at 9V, because otherwise it would not be possible.

I attached my chart.
[Xperia Z2 Android Development] kumbangdesa:
This is max value I can get. Using aukey qc.
[Xperia Z2 Android Development] TheFerhatKing:
Wait, I found it..

Every speed under 2A isn't QC2.0 and how it would even be possible to charge 60% (or even 40-60%) in 30 mins when it charges our device with 1.7A (per hour!). The charging rate I saw on the video in the first post, yesss this was QC2.0, that is what we need. But thanks for your help..

Sony Xperia Z2
[Xperia Z2 Android Development] Jackos:
Well, so it means that the UCH10 isn't capable of QC2.0 as advertised.
[Xperia Z2 Android Development] TheFerhatKing:
Maybe, but [MENTION=3783716]showlyshah[/MENTION] use the same charger like me, he had 2.2A charging on japanese firmware and I've got 1.6-1.7A charge.

Sony Xperia Z2
[Xperia Z2 Android Development] Jackos:
I added the charging speed from the third day log and it seems it's charging faster then the QC2.0 standard in Qualcomm promotional video. I don't think this is right.
[Xperia Z2 Android Development] Jackos:
SO-03 firmware on the Z2 International charges the device 1,37 per minute, while the QC2.0 promotional video shows 1,23 per minute. The Nexus 6 they used for the promotional video had a 3220mAh battery, so it's close to the Z2.

So basically you'd need a kernel change to archive higher voltage it seems... The file is msm8974pro-ab-shinano_sirius_common.dtsi

[Xperia Z2 Android Development] TheFerhatKing:
Did they start from 0% or from 20% like you?

Sony Xperia Z2
[Xperia Z2 Android Development] Jackos:
No, they were 20% after a few minutes. Well, my chart is a bit weird :P You just need to check the angle to see how fast the devices are charging.

I modified it a bit, maybe now it's not very accurate, but shows the point:

And yeah, that kinda proofs that the device isn't charging as fast as it could.
[Xperia Z2 Android Development] TheFerhatKing:
Yes as we see Qualcomms QC2.0 (50-60%) is way faster in 30 minutes as we.

Sony Xperia Z2
[Xperia Z2 Android Development] Jackos:
Unless we have a kernel that allows higher voltage I don't think that's possible to do via system modification :)
[Xperia Z2 Android Development] TheFerhatKing:
Well you're right, but I think with a great teamwork we'll get the same speed like Qualcomms QC2.0 or that one from SO-03F :)

Sony Xperia Z2
[Xperia Z2 Android Development] Jackos:
I think that the S0-03 firmware installed on the Z2 International might have a bug that allows the device to charge too fast. Because that's way above specification and probably damages the battery.

I'd like to see how fast a genuine SO-03 device charges with UCH10.
[Xperia Z2 Android Development] TheFerhatKing:
I think it is normal QC2.0 speed

Sony Xperia Z2
[Xperia Z2 Android Development] paulwollf:
Could somebody please quickly summarize the state of development and or what you have found out so far and how the current solution works because I am willing to buy a qc charger and participate in development.

Thanks
[Xperia Z2 Android Development] Gmobilize:
[MENTION=4754591]TheFerhatKing[/MENTION] clearly what you stated that all qc 2.0 chargers work 2A and up is incorrect, on 5V maybe yes and 9V but not on 12V, most of the chargers i checked including HTC Rapid Charge, Motorola Turbo Charger, they all have the max output of 15W which means : the higher the voltage, the lower the current. I would be happy if you can show me a charger with the specs you mentioned..

[MENTION=856195]Jackos[/MENTION] first of all, thanks for your effort !

Second, about the results, did you achieve the 9V or did you get ir from the fact that you were charging with current that matches the 9V one?

You might want to get a usb dongle (charging doctor), so you would get more accurate external measurements, cheers!
[Xperia Z2 Android Development] Jackos:
I'll need to assemble or buy me a dongle that measures the voltage - otherwise I'm just depending purely on software - and it's getting me false results. I guess the hvdcp is getting false reports of enabling the 9V, because the device still charges not that fast as it should.
[Xperia Z2 Android Development] TheFerhatKing:
Can you tell me please how it would then be possible to reach 60% in 30 min like Qualcomm said?

Gesendet von meinem SM-T230 mit Tapatalk
[Xperia Z2 Android Development] Gmobilize:
Sorry, i wasnt able to get full info while i was on phone, so basically to get that from hardware side we would need a QC 2.0 charger with 18W (9Vx2A as qualcomm test suggests)currently offered by brands such as tronsmart,tenergy,verus and aukey,cause oem chargers seem to be 15W as i checked, but it shouldnt be much difference.

From software side : we should ask the devs, as for what works.
[Xperia Z2 Android Development] Haldi4803:
Currently on AndroPlus kernel v63, with or without hdvcp command i'm getting 1350mA according to Ampere :(

Can you recommend a cheap dongle (about 4-10$) that works with 9V (or even 12V... future proof ;) ) and still connects the USB ports so Quickcharge 2.0 works ? Most i've found only work up to 5V

Yeah... and you need to use a good USB cable if you want to cut that open ~.~

I've used a cheap usb->microUSB cable that is about 10cm long for this test and it doesn't charge at the same speed like the normal cable :( i don't really wan't to cut this other cable open.
[Xperia Z2 Android Development] showlyshah:
That is not true, atlest i think so... Know why? Becoz, our battery only need 5 or less than 5 v ( 4.5/4.6 v) to charge. And yes applying high voltage to it will damage it, this is true for every li-ion mobile cell out there. Whether it is qc or not.

May be qc is another trick if pumping up the battery with higher currents ( my 100% belief, ) since high volatge is not an option.

And more amps flow should need more thick wires and contacts, and since usb 2 port is comfigured ( hardware wise) for 1.5 to 2 amps flow atlest in normal mobile device ( exceptions are there), flow of higher current through it will build up heat and eventually destroy the contacts or wires.

A solution for that when u require more current at the battery end will be.. Using higher voltages, and low currents. High voltages dont require thick contacts. So probably qc trick is to accept high voltage and low current and then step down the volatge and increase the current at battery end. ( same thing happens in normal ac power grid, power distribution).

The electricity is generated in higer current and low volatges, then transformer is used to step up the volatge and lower the current, and then it is transmitted to consumers, at the consumer end, there will be another transformer which steps down volatge and increase current. All these are done for the sake of transmission of electricity ( you can belive me, i am an electical and electronics engineer, have learned it!!).

So.. In over case, the phone accept higher volatge ( 9v) and then the internal charging circuit lowers it to 5v or less, while boosting up the amps, and higher amps are feed to battery to pump it up quickly.

And about the writtings on charger 9v at 1670 ma ( my samsung note 4 charger) is the power output of the charger, ie, the charger can output 9v at 1670 ma, which is the capacity of the charger, and not what the phones charging volatage and current, the phone then will convert that 9v into 4.xx volts with more current. Thats is the reason you saw 2000+ ma on readings( even if the charger have only 1670 ma output), that means the battery is charging at 2000+ ma and at 4.xxx volts.

Hope u understand.

So I have a T-mobile Galaxy S4 and I had recently rooted it. Went to go flash a ROM on it and after I booted the phone up again I noticed that superuser was missing from the app list. I checked root checker and it said my phone was not rooted. Currently running 12.1 CM android version 5.1.1. and I tried rooting the phone again but no matter what method I try the process fails for whatever reason. I tried going into clockwork recovery mode but since I don't have root access it won't even let me do that. Really confused and would really appreciate some help. Thanks in advance.

Edit: By the way the ROM is running fine and smoothly. Just don't have root access and can't root.
[XDA Assist] rirozizo:
Hello,

What you need to do is go to settings, about phone, tap on build number 7 times, then go back and go to developer options, then go to root access and pick apps and adb. If it's already picked, disable it and then repick it.

Any more help, just ask HERE in your device's Q&A section.

Good luck!

Happens on both KitKat & Lolipop.

Does anyone knows how to fix this?

Hi guys, this morning I decided to root ny tablet. I flashed CWM custom recovery and then installed universal android root zip file through the recovery. My goal was to unlock the full potential of Lucky Patcher by having unlocked Root permissions. I succeeded in installing the zip file, and everything was perfect. Unfortunately after custom patching Google play with LP, it kept crashing on startup. So (my bad) I decided to revert to factory settings. By doing this I'm now stuck in this never ending bootloop. I tried reinstalling .zip file through the use of ADB sideload, but when I exit that menu to reboot the device after having installed the .zip the device boots in CWM recovery mode.

So first off Ive used the search Ive used google search and Ive read the wiki. Still unsure of the answer.

Whats the advantages to updating the radio? does it manage power better? get better reception? In my search Ive also seen updating to a trinity radio but not its rom? Can some one shed some ligh on this for me? cheers
[8525, TyTN, MDA Vario II, JasJam General] todd_jg:
Yes to all of the above.

Radio updates are generally "tweaks". Many are carrier-specific and add performance boosts specifically to a carrier.
[8525, TyTN, MDA Vario II, JasJam General] gerald_s:
In addition to todd:

Although some of the updates are carrier-specific you should try it in your own network because its possible that its working in your network much better than in mine.

Radio Update

As compared to what other radio? 1.38? IMHO 1.40 was better than 1.38, but now I am trying to use 1.48 which was recently released... As mentioned, the area that you are in, will greatly influence your decision as to which is better... There is a chart somewhere on this forum, you can use the google search function in my signature below to locate it... The chart is supposed to be a compilation of the different roms and what people thought about them... Actually, it was an opinion poll... So you can take that with a grain of salt...

Maybe someone in your area has posted their results and you can try their answers...

I believe the poll was entitled, "Which Radio works best"

[Sprint Samsung Galaxy S6] shawn.irwin:
I'm having a new issue with recovery. So for some reason I decided it would be a good idea to try to flash twrp via the twrp app to see if it would fix the inconsistency of twrp loading/not loading. Stupid decision. Twrp stopped working completely. It would load to the menu but was unresponsive. It also kept the phone from booting past the galaxy screen. I tried odining twrp 2.8.7.1, 2.8.7.0, 2.8.6.0. No change. So I odined the of7 tar, updated to ofe, odined the ofe rooted kernel. Phone booted and worked fine. So far so good. Then I tried odining the 2.8.7.1 recovery. Same issue occurred again. I have no idea why... So I had no choice but to repeat the whole tar/update/root process to get the phone back up and running. Now I am just rooted on the stock ofe and can't figure out how to get the recovery to work so I can get back to twisted rom. I even have a backup, but I can't restore it without booting into a working recovery. Any ideas on how to fix this would be greatly appreciated.

[Onetouch Idol 3 Q&A, Help & Troubleshooting] BDestroyer8418:
Posted this on reddit but figured might be helpful on here.

Did some testing with the phone with very little apps for the last day. Decided to go to the play store and go to my apps and started DL'ing my apps I mostly use basically everything that's on my G4. Phone froze rebooted OK whatever, rebooted again, again, ok stuck in reboot loop. Called Alcatel was able to do a master reset took maybe 10 mins for it to load back up in Android everything is froze and just reboot loops again.

I can't even power if off well I can but it power's back own and does the loop. Waiting for the battery to die. Now here's a reason why removable battery is great.

Seriously WTF happened.

After talking with Alcatel and Amazon they are sending a replacement with 1 day shipping be here tomorrow. Wonder if I should even bother with it. Was going to mostly use it for my 2nd line for a Hotspot for the Data and just a backup to my G4 and or rotate them.

https://vid.me/grFZ

Now I do recall after it first froze and rebooted it said Android is updating or whatever that screen is. I recall the phone having 2 updates it updated though the day before. Should have the replacement on here later this evening.

I had CPU temp app running so I could see what app were heating up the phone when I used and when I had Google Maps on it the car it did heat up to the low 70's C once in awhile and was sticking mostly around 67-69C did the phone get too hot. Not even sure what the overheating temps are for this.

Probably just a defective phone but was fine running basically not added apps just installed NoChromo, Battery Monitor Widget, CPU Temp, Netflix, Rhapsody, Signal Check Lite, Speed Test, Spotify, I believe that's what I had installed before the issue. Then I just went and download everything else I usually use at once.

[Onetouch Idol 3 Q&A, Help & Troubleshooting] BDestroyer8418:
LOL could use a bowl of those.
[Onetouch Idol 3 Q&A, Help & Troubleshooting] famewolf:
More than likely either the 1st or the 2nd update applied to your phone put it in a bootloop but you would have had to click on them to allow them to install. Going into recovery via rebooting till you first see the alcatel screen and then holding down vol up would have allowed you to do a factory reset which in all previous cases of boot loop being mentioned corrected the issue.

If it wasn't the updates then one of the apps downloaded did not work well with the phone but a factory reset should still have fixed that, unless you were installing apps that use superuser in which case you should first have at least booted twrp and backed up system if not all the partitions so you could do a restore. Remember these suggestions for your 2nd phone.

Ideally we need someone to back up system both before the 1st update and the 2nd so we could "downgrade" if necessary. Some have complained the 2nd update caused a bug that makes making google voice calls unavailable.
