I got the official Nexus 4 wireless charger from Google around a month ago. I constantly use Tunein Radio, and like to use JellyDream Daydream Pro when I put my Nexus 4 to wirelessly charge on my desk. I have noticed that my phone will not charge and remain with the same battery percentage for hours, and many times even continue discharging (slower than usual though). I was wondering if this is normal, or if there might be a problem with my wireless charger/phone. My phone is rooted, but I don't think it's the rom that I'm using, because I have tried both Paranoid Android, and AOKP with the same results. If anyone could help, it would be greatly appreciated. Thank you.
I am having the same issue. All I have changed on the phone is the kernel and have always been on stock rom. It's really annoying because it worked perfectly fine before I flashed kernels. Now I can even flash back to the stock kernel and it will still not work right. Jumps in and out of charging and then finally just stops charging all together and I have a fancy phone stand that does nothing. I'm still trying to tackle the problem but no luck so far.

Yeap, apart from what I said on the main post, I have also experience my Nexus 4 jumping in and out of charging and then not wanting to charge at all.
Maybe you are discharging the battery faster than the wireless charger can charge it? Using tunein radio and daydream will do that.

Hi I have been viewing these forums for a long time now and wondering if any of you good guys could answer my question since I've searched google from top to to bottom with no joy .
Basically, I recently updated my firmware through odin to the latest xxubmea that incudes several fixes including the copy to sd option. As far as the performance goes etc everything is fine except, I was adoment the charging speed had got a lot slower. To prove this I downloaded 'galaxy charging current'. It was as I thought only showing 1200mah through the stock 2a charger while using the device. I then turned the screen off and noticed when I turned it back on you could just catch a glimpse of a 1900mah reading before dropping to 1200mah again. Further to this I decided to pop around my mates who is still on the original firmware and to my shock was recieveing the full 1900mah when using his device. It now appears that Samsung have physically limited the charge rate of the s4 by nearly half and in my eyes it's very noticeable. Now when I am getting ready to go out and have the radio streaming the battery life won't charge anywhere near as much as before meaning my battery is most flat by the end of the night.
I know one way of getting it to charge at full speed again is to just flash the old version again since I have folder mount and never really had many noticeable problems with it anyway.
Does anybody know why Samsung would have reduced this current? Since the speed it charged was a big bonus for me.
Also does anybody know anyway I can get it to charge at 1900mah in use by flashing a kernel or changing a particular setting or downloading an app etc?
Many thanks
Lee
are you really you sure that what you saw in your friend's S4 is correct? afaik charging rate will normally go down if you are using the phone
try other charge monitoring software such as battery monitor widget

On MEA (Omega 5.0) or even MF4 (Omega 6.0) software i was able to get 1900mA charging no probs, but now on Omega 7.0 XXUBMF8 i get only 1200mA. I`ve tried it on stock and custom kernels so the problem exists
Samsung limited the charging to 1200 when screen is on.
Screen off is still 1900.
This will limit overheating while using your phone with the charger connected.
Want the battery to charge faster, just leave the phone with the screen off.

I'm looking for the closest to 4.3 stock kernel that supports fast charge. Any idea?

Did you try Franco Kernel with his paid app ?
It support usb fast charge and many stuff like headset gain and volume boost.
Its stable just like stock... no issues since 3months
Yes I have, it's what I had been using until now. However, the fact that I had to flash the whole phone to upgrade to 4.3 because his kernel touches all kind of weird stuff is holding me back. That's exactly why I want a close to stock one.
Dear all,
I am running a Purity 4.4.2 and it's just perfect.
I would like to use the fastcharge feature, therefore I am looking for a kernel that support it.
I am aware that Franco kernel and a modded version of semaphore has it.
The question is pretty clear: which kernel is the best choice to have the fastcharge if I don't care of any other feature. Moreover, I would like not to experience troubles or lags..
Thanks!
MJ
Fast charge is fast charge
There is no best "fast charge"
There is no best kernel. Its up to you to make that choice.

You are perfectly right. That's why I asked for "the simplest" kernel. Since I am looking for only for fastcharge, even a stock kernel with fast charge is good.
As far as I know, franco and sempahore are quite complex kernels, loaded with features.
I am just looking for the simplest kernel possible
have you tried hells-core ?
since i know, has no oc, not loaded with a lot of features and is very stable.

I second this. Fast charge works nicely too.

Seems like you got your Fast Charge question answered.
No best kernel under the guise of "simplest" are allowed. Takes 1 flash and about 1-2 battery cycles to seem the benefits or hindrances of each. What works for me,may not work for you as we have different usage patterns.

Hi Guys,
Been following XDA for a long time but never had to post anything as everything had already had an answer to my question.
I know there are a lot of threads about battery drain but for some reason, everything I have tried has seemed to help minimally.
Here's the rundown.
I have a Galaxy S5 G900I running G900F custom rom, Resurrection Remix 5.6.7 Marshmallow.
Previously I was running the lollipop version of Resurrection Remix and battery was fine.
The phone is over a year old, but I have tested the battery with another S5 my wife has and it is perfectly fine. It charges fairly quick when the power is off on the phone and still fast enough while it's in use. Even if I am to open up a game on my wife's phone with my battery or hers, the battery continues to charge slowly while in use.
On my phone however, switched with both batteries, the drain is astronomical. I tested playing a game and I would lose practically 1% of battery per minute while in game.
What I have done so far is, installed Xposed, I have Amplify running following various guides which has slowed down the drain of my battery, I have installed Greenify which has also helped. I've turned off the scanning of wifi and bluetooth in locations. I have tried going back to stock rom which does help but it doesn't help me figure out the issue I want to fix.
I have tried switching power points in the house, changing usb cables, changing chargers, all of which do not help my phone with either battery, but on my wives it is fine.
I have also set CPU profiles in Rom Toolbox to lower CPU usage in idle, lower than 15% battery, while on charge. As of today, even while using the phone, I have limited the max CPU usage.
Prior to this latest updated Rom with Marshmallow, I could use my phone and have it plugged into my USB 3 on my PC and it would charge while in use unless playing a game or using a high demanding application, in which case, it would slowly drain. If in a power point adapter it would charge regardless.
Now, even in idle, on my PC, it drains while charging, and charges extremely slow on a power point.
I have searched for over a week trying to find any sort of guide or help with this problem and I have certainly minimized some of the drain but this is ridiculous.
If anyone has any idea's on what it could be, please let me know. I have tried cleaning all the dirt and gunk out of the charging point, the only thing I haven't done is pull apart the phone to see if its a hardware problem (Which I am starting to think it might be.)
have u tried with another usb cable?

Yes, I have tried various USB cables on various USB chargers, even non USB chargers I had laying around. And as I said, I have also switched the batteries into my wife's phone and they charge fine there.
The problems only started once I upgraded to Marshmallow.
It also persists when the phone is switched off and charging. It's just slow.

Do they persist while on L? Could possibly be a conveniently timed hardware failure.

Your default CPU 1900.0 MHz (8-core) this now running at 2400 MHz, you are lucky that the phone did not permanent damaged up to date.
Find S5 G900I compatible ROM and not what ever ROM.
try to factory reset your device 1st. if its only started after MM update then must be software issue.

Done that. Had a previous ROM installed and the battery was better. But I want to know how to fix the issue, I don't want to revert back to older software.
I know its possible because even with the same rom installed, before I bricked it and forgot to back it up, I had better battery life.

First thing I did was cap the cpu usage at 1900mhz.
Go back to stock lollipop and check if u still have the problem

It seemed that you did that unsuccessfully, OR you battery gets old and needs replacement.
At about 400 charging times, the battery this is now at 80% capacity or less.
In my S5 I have permanently activated basic power saving mode, this clocks the CPU always lower than Max.
The phone seems happy, and I am too.
By using one Qualcomm App I discovered how low is low with basic power saving mode on.
Flash a custom Kernel and you can set it more or less as low as you like
S5 this is a very complicate device, I am trusting only Samsung about it.
If this was an old tablet with out ROM support from anywhere, in this case I would.

Having trouble finding a custom ROM that's a stable build that runs on S5 and on Marshmallow. Would you happen to know any in particular that I could use?
consider buying a new battery

I use a stock MM port G900FXXU1CPD7-BTU
But you could just flash a compatible custom Kernel and then have control over the CPU/GPU clocks

This one looks like it supports stock TW 6.0.1 MM for the G900F
http://forum.xda-developers.com/gal...kernel-phoenix-kernel-v7-marshmallow-t3340407
But like always, do your own research before flashing
EDIT - Actually it looks like the dev has left out OCing from this Kernel, not sure about downclocking/under volting - maybe request it in his thread
