hey guys i bought my niece a 2012 nexus 7 it has the axus charge with different usb cable but it charge so slow
i was wondering if there is a rom with better charging speed
i havent root and is wifi version
What does "so slow" mean? As in, how many minutes to change 10% in charge?
One thing you can do to troubleshoot things is to see how long it takes to charge the tablet when it is completely shut off. It should be pretty obvious that "the ROM" has absolutely nothing to do with that scenario. Wait till the tablet is discharged to about 10%, shut it off, and charge it for 90 minutes. If it is charging normally it will be close to 70% charge when you boot it back up.
If your tablet charges slowly in that case, then there is a problem with the charger, cable, or battery in the tablet - not the ROM. So, you should surely check that out first before you start worrying about software.
A nominal N7 (2012, WiFi) will charge from 5% to 100% in about 150 minutes: 2.5 hours. That's with a STOCK ROM. If you look at the battery capacity, that works out to a minimum 1.73A charging rate. (4.325 Amp-hours / 2.5 hours = 1.73 A). It's actually higher than that because a certain amount of charging current is "lost" to heat generation while charging.
The tab will ALWAYS charge slower than that if it is in use, especially if the screen is on and the owner is doing things like streaming data or playing games. If it is under heavy use, the tablet itself could easily dissipating 1.0 A of current... so in that case the 2.5 hour charging time would be over twice as long: over 5 hours.
The "fast charge" ROMs are not what you are thinking. "fast charge" there means "fast charge under conditions normally restricted to low currents when data transfer is taking place". If you are using a charge-only cable (such as the OEM charger and cable), the tablet should always be able to draw close to 2A of current with ANY ROM - there is no data connection present, and the tablet is not restricted in the current it can draw.
The ROMs don't really throttle the battery charging rate except in that very specific condition: when there is a data connection present. So, worrying about which ROM is installed really only applies to people that want to use a Y-cable and a live USB data connection (tethering or an OTG gadget attached) - for instance in car installs or maybe with data tethering via USB.
good luck

Get a better cable. I was using a third party cable on my Nexus 7 for a while and realized it was only charging about 10-15%/hr.. Changed the cable out for a better one and it charges at the normal rate now, 30%/hr or so.
Do check for loose connections for both battery connector and usb ribbon connector (under speakers). I’ve opened the back cover to check after slow charging problems and was solved by opening and clipping back the usb ribbon connector. Charging's back to normal now.

thanx bro
So i just installed Cyanogenmod 12.1 to my mobile. I had problems with slw charge before cm too. I have got the stock samsung charger, i have tried 2 another charger too but its the same, and multiple plugs but no change. There is nothing in my mobile ehich could cause this. Sometimes even my mobile discharge a little while its plugged. I turn off everything, wifi, sync, etc.. My charger doesnt fit very well to my mobile port, so i have to move it and fix it with something, to connect, but its working , and i can copy , paste from the mobile while connectd to pc.
Ampere says that its charging with about 60 to 120 mA.
I dont know what to do, maybe my mobile port damage, but maybe there is other sulotion.
60 to 120mA, bro that's not safe. I think you'll have to clean the connector or change it and then check the charger
What do you mean that its not safe?
Two possibilities
1)- your charger is screwed up
2)- your port is dirty (maybe)
What would be the good mA ?
Mine is from 600mA to 720mA
Wow i found out what was the problem. I used a distributive, or how you call it (transalated it ) and from that it's only charging with an avarage of 100. Now i connected diirectly to the plug, and it's charging about 600 to 700 mA. I would never think that would be the problem, becaouse i used the distributive every time, and it was working fine.
I have the same problem. First noticed the problem on CyanogenMod 12.1. Reverted back to stock, and I was getting 100% full battery. Then, after a while I noticed that my battery was bulging, so I changed it. Got a new battery, the problem is still there even on Stock ROM, this time. Got a battery App called Battery Monitor Widget, or something,,, to check my mA flow while charging and when the battery is empty I was getting 850mA, but as it was getting fuller the mA flow value was dropping. Today for example, it was fluctuating at around 70mA at 90%, and it wouldn't go higher. I removed the battery for a few minutes, then put it back in and it indicated 100% when I turned on the phone. I waited till the phone was 90% battery and plugged back the charger, and the mA flow was around 400, and at 99% it dropped down to 175mA. I don't know what causes this kind of behavior, but it's frustrating as hell.
My charger charges at 2A, and let me tell you, this thing charges pretty fast!!
My Galaxy s5 g900f overheats with anything i do, it overheated in recovery while i was trying to do a nandroid restore, it overheats while charging (turned off), it overheats when i turn it on, i see the samsung s5 animated logo altough very laggy, and when it turns on i enter my sim password and all i see is the notification bar and the rest is a black screen nothing works whatever i do.
When i say overheat i mean the screen and the upper back of the phone are hot, it all happens in a matter of a few minutes.
The CPU got upto 73C while i was doing the nandroid restore.
I got the stock charger and cable, never changed any hardware inside the phone is everything is genuine.
I am running Xtresto lite ROM for the past 4-5 months with no problems. (So i guess it's not the rom?)
Please help.
Thanks in advance.
edit: i've got it on the charger now and it's off and just noticed that the phone is discharging although it shows that is charging, it only charged up to a point i guess and now it is falling while on the charger on the wall
charging will be hotter than unplugged actually, also in my experience within TWRP with its temperature on screen, i also reached 70 degrees simply going through menus... which means there is no cpu idle state without a kernel/rom
so... are you able to run a temperature monitor (maybe with kernel adiutor) or is the whole thing going to freeze or shut down? there is supposed to be thermal throttling depending on kernel & if some parameters have been turned off (you can see them in kernel adiutor)
hopefully it's just some app failing or malware, not a hardware failure... is the phone allowed to turn on while usb plugged in WITHOUT battery? are you willing to wipe the OS? i'm not sure you got your nandroid backup completed (also i have no experience with that... i used TWRP to backup but never tried restoring when i moved from CM12 to CM13, my internal storage was untouched anyway)
edit: just reread your off+charging situation... is this a 2A charger that you know has been able to quickly charge in the past? (like, 0 to 70% in only an hour)
have you inspected the battery, its metal contacts, & the phone's metal contacts for the battery?

Hi, thanks for the reply
No, i cant run any app because as soon as i get in the os its just the notification bar and a black screen, my apps flicker for a second once in a while but there is no way of using the phone, not even in safe mode.
No, the phone can't run without a battery and am pretty sure every phone is like this. You need the battery plugged in for it to work whatsoever.
I have no choice but to wipe the os and reinstall it i backed up everything i could and possible.
This is indeed a 2A charger, it's the original samsung charger that came with the phone. The metal contacts seem fine and the battery is fine. It's not the battery that overheats it's the rest of the phone. When the phone is hot i removed the battery to check if it was the source of the heat and it wasn't.
edit: the battery is draining fast! i can't even charge it, it loses battery while on charger too (the phone is off)
edit 2: i made it until the wipe, then i went to install my rom and it turned off before i reached the point of flashing (thank god) and i guess its draining so fast i cant charge it
Maybe an external battery charger might help to at least give it sine juice to install stock. I'm sure the kernel is linked to charging while powered off. So fingers crossed its a software issue, though this those sound kind of worrying behaviour. External battery chargers can be bought quite cheaply of eBay. I bought a USB battery dock and a better quality male to male USB cable as provided one is crap, and use it with my original Samsung charger. Don't trust the wall plug in types as their all made in China... Best of luck.

geeze, well it does sound like 100% cpu usage... like those bitcoin mining malware
i would try to flash a fresh replacement or stock kernel+bootloader+baseband with root disabled using odin or something, we need to prove that the software is clean
as for the temperature, if it's winter where you are... get the phone some cold air (edit: by the way, lower temperature means lower wattage... only problem is battery capacity might also appear lower, so it's only good for being wired)

I will have a look into an external charger or look if someone can lend me their battery to test. Happy to know that the kernel is linked to charging, i still have my hopes to software!

where do i find those files for odin? sammobile? yeah it's winter my issue now is that it is completely dead it's not responding when i connect it to the charger at all. I tried 2 original samsung chargers. 3 different cables. my gooood! its driving me nuts.
anything i can do without sourcing a battery or an external charger? not sure i can source one here and dont want to wait for an ebay one really.
Could be a dud battery at the end of the day. Dodgy batteries can cause all sorts of issues. One test is to try spinning the battery on a flat surface. If it spins, its expanding and faulty. Though this isn't the only sign of a dud battery.

already did that, not spinning. lets hope it is still a faulty battery
HI everyone Anyone have charging problems with Note 4 ? No fast charging , not charging at all?
I was having an issue with no fast charging. Changed the usb cable and blam, works like a charm now. Check your cables first before buying a charger.

Everything was working fine for me and than before 2 days for no reason fast charging don't work for me for no reason with my original cable and adapter for fast carge. I tryed carge on other 5 cable and adapters and the phone don't won't even charge at all ...nothing happens when I plug in ....only on original charger start charging and 2 min later start discharge and pop up message if I want to share power (give power to other device )???
In the end my phone died and I couldn't charge it to start up ...so I buyed external battery charger for note 4 and charge battery , and Flash PIT file + original stock rom in 1 flashing process and now charging on all 6 chargers with no problem.
I was trying with flashing 4 different stock firmware but didn't help until I included PIT file.
Before I across charging problem I was running Kybi note 5 port and was working week's normally.
Now I'm afraid to run any custom rom ...lol
Humm that's a strange problem to have. You can check under the battery setting in settings and make sure fast charging is checked.
One night i was charging my Note 910g as per normal using the fast charger. The next morning it died off and when i press to turn on, it warned me that there was a high temperature of over 90 degrees and therefore caused the shut off. From then on i cant charge using the usb port on the phone. My laptop cant detect the device so ended up charging using the portable cradle. Found out the charging port on the phone shorted. So i ordered from eBay and have it fixed cause i cant send to Samsung even it is only 5 months old due to tripped knox status.
Hello,
i'm new here and i'd be glad if someone can help me. So i got my phone a month ago and i noticed that while its charging (with the original charger) and while using it in the same time it almost does not charge at all, still when it's not used it does actually fast charge. As a previous samsung user, i never had this issue with samsung phones (they always fast charged even on heavy use).
That's one problem, the second one is scrolling isn't smooth. Yet my internet speed is 1GB at home although i don't see it related, overall scrolling let's say for example Facebook, snapchat, browser, it gets slow at few times and it ain't smooth like i expected it to be.
My device isn't even rooted so i haven't messed with it anyhow, running usual diagnostics and clearing apps regularly, downloaded just few social media apps so no heavy games on the phone but still i can't figure out if it's just my phone or is it the lg g6 like that.
thank you
1st i wanted to mention maybe the problem is your outlet in house but, yes G6 is charging slower when you use it on your charger.. And when it comes to fast charging to mine it tooks 1h and 40min from 0-100% bit slower than competiton models, but again fast enough.
When it comes on smoothness i am on V10T EU update and the phone has no laggs at all. It did had on past versions. But with this V10T i hadn't had any smoothness issue.. It really is great, and for playing with the phone while charging i wouldn't recommend that. It can really take effect on your battery.
Powered by LG G6
The scrolling lag sounds like there might be something making the phone work hard. Heavy usage would also make it charge more slowly than expected, because some of that power is going to operate the phone rather than into the battery. BUT I don't think it would prevent the "fast charging" text on the display.
It is remarkable how badly-behaved apps can be - I'd remove/disable your apps one at a time and see if one of them is responsible.
Try a fully compliant aftermarket quick charge 3.0 charger, it should charge much faster. Unlike a QC 3.0 charger, the charger bundled with the phone does not include 12V charging mode, so it's not allowing the phone to charge as fast as the phone can handle (the phone is fully quick charge 3.0 compliant and can charge faster than the bundled charger is capable of doing).

Yup, that's true. BUT I have s7 and g6 and both are slowly charging when I'm using them, phone would get too hot if it would fast charge while using it
I appreciate all your replies guys. Thank you.
Although i noted i dont have any heavy apps or heavy usage, the scrolling lag seems like a lag to me because i got used to faster phones before. Or maybe it is the original cable i need to change as you guys said. Anyway thanks again
I also encountered slow charging problems, but it seemed to be the cable, in some position it worked and in some it did not. I've bought an one plus dash cable for about 10 $, red one, and no problems since then. The cable is more thicker and robust, I highly recommend it.
Hi, I've got this problem: sometimes when I plug my G6 to the charger, a popup message comes out saying:
Charging slowly
Try the following if charging is slow:
- make sure to completely remove any water or debris from the USB ports.
- reconnect both ends of the cable.
- use the charger and cable that came with the phone.
Sometimes, instead, the phone starts charging normally with fast charging. If that popup comes out and I try to unplug and plug USB cable a couple of times, the phone starts charging again with fast charge.
Sometimes, when the phone is already charging with fast charge, suddenly the phone stops charging for a couple of seconds and starts again (I notice it because of the popup sound that comes if you plug the phone to USB)
I even tried to clean USB port, swapped the original USB cable with Anker cable but still using the original LG charger.
Of course there is no water in the port, otherwise a moist detector message would appear.
Has anyone experienced this problem? Can I solve buying a new charger? I'm afraid USB port might be broken

I did it recently after I upgraded to Oreo but this was happening even before I did reset the phone.

Yeah i found that funny that LG lied and tried to get by on using the chargers from the failed lg G5 shipped with the G6. They only support 2.0 charging so just use the cord and use another 3.0 block or get a portable 3.0 power pack. They are 20 bucks on amazon. Good ones too.

can this be a good charger?
I bought an used G6 without charger but I have a Pixel charger model GL0102 and when I plug the phone I cant see the fast charging notification on the screen. It only say charging.
