[Q] Nexus 10 unusual battery drain 4.3 - Nexus 10 Q&A, Help & Troubleshooting

Hi all,
Was wondering if someone could help me out, I'm having a battery drain problem while running video from an external USB stick (stickmount) through HDMI to my TV. Prior to 4.3 I never had this problem, I could always play a movie off of my USB stick and never have to worry about the battery discharging (I use the pogo cable). It's safe to say I also experience the memory leak that others have mentioned on 4.3 (after playing video/browsing for a while I'll have <200mb free ram). I'm rooted on stock 4.3 JWR66V.
Could someone offer any solutions to my battery and memory leak problems?
Sorry if this has been mentioned before but it's driving me up the wall
Cheers!

Nobody?

Phone not going into usb mode

the option of going to mass storage mode or usb charging etc help!
rooted eb13 twilight 1.01 kernel
I was having trouble with this lately then last night it worked, and it hit me- I had the stock battery in last night. I bought a 3pk of chinese batteries and a wall charger off ebay and whenever I have one of the aftermarket batteries in and i plug it into the computer it gives me some bs message about the battery not being stock and it won't charge it or let me transfer files or anything. So idk if you're running the stock battery but that is one possible cause for that problem. Running midnight4.2.
Try restarting your phone. This problem seems to be intermittent.
Running a stock battery tho had Bo problems with my yoobao andvive rebooted many times

[Q] Different Battery Question- Phone used to charge fast now charges slow

Hey Guys,
So I searched throughout the forum and could not find anyone who posted about this yet. Since I got the galaxy S4, I've noticed my phone charges incredibly fast. Plugging it in for 20 minutes will make my battery go up somewhere in the range of 20% at least. For some reason over the past two days, my charging time has slowed down drastically. I now plug it in for 20 minutes and I'm lucky if the battery goes up 2%. No drastic changes to the phone. I have rooted it, but haven't done anything else besides freezing some bloatware using titanium about a month ago. Anyone know what might be causing this, and what I can do? I have BBS but I don't think thats much help here.
Thanks in advance!
I would start by ensuring the contacts within the usb port on the phone are clean. I would also try a different usb cable. Stock cables are not known for their quality.
Thanks!

[Q] Charging Nexus 10...

I`m represantate 4pda thread of Nexus 10. Lots of people experience troubles with charging our Nexus (including me).
Using native charger in turned off tablet it gave only 50% in 8 hours (in my way)
Others say approximately the same.
I have root, unlocked boot, use Gravity Box (xposed). (It would be normal if my case were sporadic, but...)
Do you know any solve of situation?
I am also experiencing this lately. I'm not sure if it's from the kitkat update or not, but same story here, I leave my tablet charge overnight and when I get up it's at 75% after at least 7 hours of charge. I tried stock kernel, thunderkat and ktmanta, didn't solve the problem.
I've ordered and waiting for N10. I was going to immediately unlock, flash stock 4.4 then root and apply Kernel
I've also ordered a Pogo cable as owners seem to get a faster charge, also to reduce wear on the microusb. I assumed I would be using the supplied microusb PSU?
I've had a N7 for 17 months and on it if I was using it, even with 2Amp PSU, it would often just hold its charge, so not gain charge, when used, I'd have to leave it screen-off to charge. So with N10, you've got experience even when OFF (powered off, not just screen blank) it isn't charging? That sounds weird. If however, it is simply screen off, then go to your battery and see which app is keeping your power consumption up and do something about that app surely???
I noticed it immediately with the micro USB cable and stock charger I have been using since I got mine (just after release). Usually 1100-1700 mA charging. I noticed the minute I updated to 4.4 that my charging averaged 600-800 mA on the USB. After an 8 hour charge it was like 46 percent. It really scared me, thought my tablet was going. I tried switching cables/chargers. Stayed the same.
I switched to the stock wall wart and the pogo plug and it jumped right back to 1700-1800mA till 80 percent charge and then starts dropping. Something it had never done with the pogo. I had to search drawers to find the pogo since I had given up on it's poor performance. It has always been about or less than 1000mA, which is why I always used the usb charger. It seems to be much faster charging now, but only with the pogo. USB barely seems to provide enough power to maintain the charge!
That was the first day on 4.4 manual update, haven't checked since that minor update to krt16s to see if it changed. The pogo seems to be quicker than any charging was.
Yeah my problem also appeared arround the kitkat update.

Charging speed super slow! (~8hours to fully charge)

Hey Guys,
I really dont know what to do anymore.
My OPT needs 8 hours+ to fully charge everytime!
If I use my OPT to watch Videos it even drains faster than it charges.
The strange thing is if i shut it down and let it charge in the shut down mode ( with only battery visible on screen). The Charge time goes down to less than 2h. So a very normal charge time, that I experienced before.
It started the strange behaviour after i had OOS3 installed for 2+ weeks and never gone back.
Things i tried:
different roms: OOS2, OOS3, CM13, Exodu. Currently I am on Hydrogen OS-
different kermels: Boeffla, Sandy, AK, Stock.
different firmwares and recoveries (I know its useless but i tried everyhing)
wiping complete phone and reinstalling from 0 several times.
different cables / adapters and wall chargers. (Normaly using a 5-port 40w anker charger with anker cable. Every other config like car charger or orginal power adapter&cable same problem).
I have no problems with other devices like my tablet, powerbank, nintendo 3ds, Videogame controllers,... And even the OPT works but only if i shut it down.
I observe this problem now since the start of this month. Its so annoying i am basicly forced to have a power bank always with me.
I really hope you can help me
Could it be an update for one of your apps that has made the app run wild causing it to put phone under constant use? What does battery stat tell you about battery usage? Tried installing system monitor to check on installed apps and how much CPU time the use?
I googled alot and found something about ES File explorer that messes with charging. I deleted it now,
Other thatn that i only installed very common apps like whatsapp.... I dont think its the apps but its worth a try.
Running complete stock for 1 day with no 3rd party apps and recharge.
Same here...some voltage problem in your home....try charging turning phone off.
i would suggest you to use a voltage stabilizer in between your wall plug and your charger,
the one that you normally used for desktop pc

Same issue here. Tried every sort of things. Was initially on CM13 Seraph08, moved to Grarak, then back to OOS3. No improvements, as the OP mentioned the issues are observed from the month of May. It takes 7-8 hours to charge 100%. Did anyone approached service center?
Have your also tried different cables and chargers? As quality of the cables that came with the phone can differ, and also the chargers. Some chargers seems to barely be able to output 1A even, nearing USB:s 800mA charging.
i also having same problem check the charger and cable if u r in oxygen os factory test mode
So most of the answers havent read my first post prolly.
I finally got the OnePlus sup to exchange my phone. With the new one i have no more charging problems.
So i think it was a hardware defect but I am not 100% sure.
how did u get the exchange of the phone ??
was it rooted ??
if it is having a custom recovery will they reject the warrenty ??
please reply asap
Just an observation, Benschholds kernel seems to have fastcharge support. See this recent commit in his source:
https://github.com/benschhold/andro...mmit/b5d1eed20c12a9e9db5128ace98efa51b0a97e19
I noticed these values aren't updated in the AOSPA kernel source for our device, so I'm going to try flashing this kernel and see if it works with AOSPA.
Edit: interesting, the stock OOS2 and 3 kernels do not have these values. So this may not help, or maybe it does, who knows.
Edit2: I tried to flash Benschholds on AOSPA and it DOES NOT WORK! I had to flash the old boot.img using fastboot to fix boot loop.
i had the same problem
i also tried many ROMs and kernels, no help
but now it's fine i'm using another cable
just change the cable(not the charger head)
right now i'm using nexus 6p cable (borrowed)
A friend was having this issue, he said he fixed uninstalling clean master app

Yea same issue in Exodus ROM.. Oxygenos 3 didn't have any issues lyk this..
No need for fastcharge in this case, OP2 can already suck almost 1,5A by default and that is a significant number, if connected to original or similar charger with high current output of at least 2A. There are ways to see exact number, like in kernel config apps (Boeffla does it for sure) or by installing apps like Ampere. Compare your cables and charger adapters
Same issue!
My Op2 used to take around 2.5 hrs to completely charge .. Just after i installed cyanogenmod 13 my charging capacity got tooo bad. Its taking more than 5hrs to charge the device. After changing roms from cm13 the battery capacity has not Changed
According to me due to some issue in cm13 the battery charging time has become too bad. Please help currently on oxygen os 3.5.8.. when i use my
phonr while charging at times it evn discharges. Tried moto g4 plus charger due to which the charging time reduced a
bit.

Oneplus 2 was never designed to be Fast Charge ready.
I've had problems like: random reboots, slow charging, battery drain. But after flashing the (considered most stable) 3.1.0 firmware + Boeffla kernel everything was ok again.
But you probably tried it already I guess.

SM-G900F Weird Charging Issue

Hey i was looking for someone who could help me with this strange issue. I owm Galaxy S5 G900F. Currently running stock lollipop rom (back from custom rom to stock to see if it helped my issue).
Everything was perfect on daily base and one night i plugged in my charger and nothing. So i first i thought battery is gone so i bought new one. Then i was checking port if its not dirty, no it was perfectly clean. I tried dozens different chargers, cables, pcs. Nothing. Even PCs don't recognize the phone. Battery percentage is not showing correctly (When i got new battery i fully charged in on universal external charger first, inserted battery and performed battery calibration from an app to wipe battery bin stats) and it's not showing correct discharge progress either staying for hours on 66% even tho i played hours of youtube videos.
Even tho i cannot charge the phone or sync it with any PC here is something extremely strange, ODIN recognize phone and i can flash stock rom via ODIN without a single issue!
Any advise are strongly appreciated.
Thank you for your help!
Ok guys, i dropped the phone to repair shop as i did not want to open my s5 without proper heat gun. The guy said it was the charging port. He said it was very unussual problem, because when the charging ports breaks usually nothing works then (regarding the charging and syncing) odin was not suppose to work either. Anyway it was the charging port. All good now.
