Just put CM11 M8 on my kindle fire hd 8.9, love it, but have one question. I notice while it's charging, the lock screen will switch between saying charging/discharging. Meaning when the screen is off, as soon as I turn it on it says charging, then 1 second later it changes to discharging and stays that way...this is all done while the screen is locked. It looks like it is charging albeit extremely slow based on the percentage increasing...but is this normal behavior?
I've already tried two different usb cables.
What are you plugging the KFHD into? I have charged mine from 1A, 1.8A, and 2.1A ports, and while I don't remember ever seeing it switch back and forth between charging/discharging. As a side note, charging from a 1.8A or 2.1A port leads to fairly swift charging (I've used the original KFHD USB cable as well as AmazonBasics 1m and 2m cables with no change in charge time).
As a side note, I am also on CM11 M8
I'm running nightly builds with the Amazon 2.1 amp charger and have not seen this problem. Perhaps try a different charger to see if it still happens, it may be the charger itself.

Yes, I'm having the same issue. In my case, the unit reports 'not charging' even when it clearly is. I have no idea what the problem is, but as long as it charges, it's something to ignore.
It's no issue of CM - this is normal when you use low-power charger (effect is the same when charging from PC or Notebook USB ~ 500mA).
When you turn the screen on, power consumption is increasing and charger has not enough power to deal with it.
I recommend you to buy more powerful charger.
>1,8A chargers should charge easily even when the screen is on.
as an update; it seems that as of recently (I've switched from CM11 M8 to Liquid Smooth v3.2) the charging has slowed significantly. I don't use it all that often, so as of lately I've gone >1wk between charges. Two nights ago I plugged it into a 2A charger (intended for a Galaxy Tab) at 24% at 10pm, at 5am it had only increased to 77%. Last night, while plugged into my Galaxy S5's 2A charger it took almost all night to charge about 50%, and this morning it stated "99% Discharging" while still plugged in.
This is an interesting thing...

Just been on a long run and used the satnav ( google ), and the whole time it was plugged into the cigarette lighter charger.
Despite this, the battery level was running down
Is this normal - that the battery drain using the satnav/gps is greater than the charging rate?
I used mine yesterday for about a 1/2 hr journey, was not plugged in, but batterey was down to about 30%, also seemd to use about 20mb for 15 miles, so watch your usage.

Its been discussed already, your charger is not powerful enough to charge it when using satnav, so the end result is that your charger is just slowing down the discharge. Happens when you are using 3rd party accessories.
Ah - That makes sense -- where can I get a decent one - at a decent price
I'm using the factory supplied lead and still get the same, also used to be a problem with my Touch Diamond 2 WinMo Phone, was hoping Desire would be better and it is... just... If I make sure it is fully charged before I set off I can do about 3 hours with it plugged in before it goes flat, I just keep switching it off while I know where I'm going and only switching it on when I don't! That way you can make it last until it is needed.
Another thing to check is that it is kept cool enough to charge, again, in common with my older HTC winmo phone, the Desire gets very hot while being used for GPS and this can be worse if it is in sunlight on your windscreen, sometimes this can stop it charging at all, (you can tell its in this state because the indicator light blinks alternately orange and green) I angle a vent so its blowing cold air on the phone and that seems to do the trick.
Weird thing with the Desire is that for me it shows the green charge light and battery full indicator right up till it is nearly dead... rather than showing that it is draining
I've also noticed with the Desire that even If I'm just browsing the web it drains quicker than it can charge, even using mains charger, I often get a message "the current is insufficient, please connect to AC" or something like that (when it is already plugged in)
I don't think the in car charger you use would make a big difference, the current/voltage for your cigarette lighter socket is limited by the vehicle electrics (I know mine is fused at 15 amps)
Pauly
You need a charger which supplies 1A. Most 12v cigarette lighter chargers only supply 500mA
I use this one, and plug the USB cable into the "quick charge 1A" socket

Are you using Bruts worldwide maps mod? I just installed it. I ran it for literally only 5 minutes, but my phone got really hot and the battery monitor shows the app used 10% of the charge (the phone has been unplugged for 24 hours). I have a strong suspicion that this app is faulty.

Basically most usb car chargers (even 1a rated ones) are recognised by your phone as a data connection and to protet delicate computer usb circuits will only draw 500mAh where your phone requires 950mAh.
An easy mod of either the charger or a data cable will solve the problem. Your charger MUST be able to supply up to 1a.

Thats why I use the Belkin one, it detects it as a charger only and charges at full rate when plugged into the 1A socket.
Anyone else notice that our Nitro is rather fickle about the power source it receives?
If my battery is completely drained, it MUST be plugged into a higher power source than USB (so far a wall charger that ouputs 750ma works) until it gets an initial charge (usually needs at least a couple of %)...Then it will accept charging from USB (USB provides 500ma).
I can tell when it's in this "state" because it remains dead if I plug it into USB and then if I plug it into a wall charger the touch buttons at the bottom flash for a few times and then the LG logo pops up and finally a charging battery icon comes on. Considering this sequence, this seems like a functionality of the phone. I wonder if this is common, my Nexus One certainly didn't have a higher-initial charge rate requirement when the battery was dead.
I've experienceed the same scenario.

Well I did notice that if it was on usb...and I had bluetooth...gps, and wifi...plus running some apps and stuff...the battery actually continued to drain I think they have the usb thing as a safety measure...for some reason...I think it's odd...but meh
try a usb cable that has 2 jacks plugs to connect to tyhe computer. These cables are often supplied with external hard drives as they they require more power than can be supplied by just one usb connection.
I was also having the problem of my p-930 discharging while plugged into compute usb jack - even when screen off nad only in charge mode. I have since bought a dual plugged usb cable and it charges now. Although I haven't tried it from a completely discharged state.
my spectrum is the same way.. i can charge it with usb.. but it takes about 15-20 minutes to get enough charge to turn on

This! I only charge with a wall adapter now. I had a hard time charging it until someone here recommended this to me.
Getting ready for a cross-US trip next month and just noticed something with my GNex vs my 4S.
On my 4S attached to my 1A cig lighter charger from Belkin, I am able to charge the batter while navigating with GPS and screen on. This is using actual navigation, not the built in stuff for iOS5 and earlier.
I simply assumed the same would be true of my GNex but I noticed today that if I am using Google Nav with the screen on and connected to the same 1A Belkin charger, I lose about 1% every 20 minutes or so from my brief testing.
It doesn't appear to be overheating as the charging lights and symbols on the phone continue to show charging and the phone isn't all that hot. It's also not been using for any really long trips yet so it hasn't had a lot of time to get super hot if it's going to.
Just curious if this is common for the GNex while running only GPS with screen on.
I did some searching but the other complaints I found involved people also streaming music while using GPS nav.
People have reported this, and it makes sense if you're on a 1A charger, especially if you have a Verizon model connected to LTE. This is similar to the complaints that people can't charge on a 500mA USB 2.0 port while tethering LTE.
I personally don't notice it draining when I'm listening to music (stored, not streaming) and Navigating, although it's usually on trips of 45min at most and I have a GSM model. My battery seems to just hold or barely charge. I'm not sure of the exact output of my charger though. It's an AT&T branded accessory with a main cable, and a second full-sized USB port.

Yup, normal for the LTE models. It was actually one of the biggest complaints when it was initially released. Turn off LTE while using navigation.

I believe that charge is 1a shared.
---------------------------------------------------------------
the next nexus needs an IR blaster. think of all the diabolical fun!
I haven't tried it on my Galaxy Nexus but his was certainly the same on my older Nexus S.
Verizon Nexus here and I have no problems in this regard.
I usually stream Pandora while using Google Maps Navigation and have a little speaker plugged into the USB port on the charger and it still charges the phone's battery.
LTE is on as well. Never turn it off.
Using the "MicroUSB Dual Vehicle Power Charger w/USB port" charger from Verizon.
Use Battery Monitor Widget and see if it says "AC" or "USB" when it's charging. You want to see AC or it won't be pulling enough juice. If you see USB, try a different cable. You can also force fast charging with the proper kernel. I use Franco, which has an option for it. That alone didn't seem to help, but I bought the Fast Charge app, which seemed to do the trick.
I just went through this myself on a 2 week motorcycle trip. I used a 3rd party GPS app the entire time, screen on, and streaming music. I had LTE on and I believe as long as my screen was set at around 65% or less I never had an issue.
So, yes it can be done. You just need to figure out the right setup. I did some research before my trip and from what I read, not all USB cables are the same. On my bike I had a low-profile dual USB charger.
90% is the USB cable.
It happens on my Galaxy Tab 10.1 with the default Samsung USB charger, when I connect it to my laptop. Then, if I browse on Internet with the tablet, my battery drains faster than charge, even if connected to the laptop with the USB.
The key is to discover if there is the USB or calbe problem with A output.

Sure enough, it was going to USB on the car charger. I unplugged the phone and went in the Franco Kernal Config and enabled USB Fast Charge. Plugged it back in and it recognized as AC and true enough, it charged my phone while using Nav so YAY!
Only problem I'm having is that on any reboot, even though it is still checked in the Franco Config, I have to uncheck USB Fast Charge and recheck it before plugging it into the charger for it to not go back to USB.

Not sure why it's needed, but after I bought this:
https://play.google.com/store/apps/details?id=com.incredicontrol.fastchargewidget
I only needed to toggle the widget to fast once, and then my problems went away. Worth a few pennies prior to the trip...
I boggles the mind why this is set up this way in stock form..
why??
BTW to the OP, I just switched from a 4S, also had a 1amp charger that did the same as yours, that same charger on the Nexus won't charge the battery with GSM model. It drains about 3-5 % over around an hour commute, more if the sun is directly on it and it gets hot.
Still, why does it seem to force a .5 amp charge when the capability is there for more??
This is annoying that you have to grab up a custom kernel to do this. With JB I'm quite happy with the way the phone is stock and non-rooted but I guess I'm going to have to root and throw on a custom kernel after all.
If you like to solder cables, you can mod your car charger to register as a AC charger.
Give me a second, I'll find the thread.

Swiftkey'ed on my CM9 Galaxy Nexus
Recently I've noticed that my Gnex battery will LOOSE charge when plugged into any power source that isn't the Samsung charger. Weird right? If i plug it into my laptop, car charger, an LG wall charger the battery will drain. It has happened multiple times where i've hit 15% battery life and plugged it into my laptop or car charger and it will loose a 1% about every 2-3 minutes.
I've switched roms with no luck. What is going on?
Its not uncommon for this to happen from a laptop port - especially if the phone is being used while plugged in. The USB output on laptops is likely not very high.
Check the amperage of the alternative chargers you are using. If its too low, they won't be able to keep up. Make sure its the same as what the stock Samsung one puts out. Can't recall its exact specs off the top of my head...
Laptop and car charger are 500mah or less. Your phone is using battery faster that it's recharging. Nothing odd about that.

I'm charging on my laptop with a cable of blackberry and no loss there. Charging with at the wall I'm using only samsung utilities so I can't help you out there..
Despite that I don't understand what that has anything to do with rom's?
I was wondering if I could charge the Nexus 5X with a 850mah wall charger, I will be using a USB C to A type USB 2.1 Anker cable to an older LG wall travel charger.
Why not? Just make sure your cable is certified

Yes it will.
I charge my Nexus 5X at 0.36 amps (measured current). I've found across all my devices, the slower I charge them, the longer they last on each charge. For the most part, the devices are plugged in over night (7-port hub), so I don't really care if they take several hours to charge or not. Even the tablets are charged when I wake up.
Sometimes this is every night, sometimes this is every other night. Just depends how much I use my phone.
Thank you guys, yes i prefer a slower charge myself too.
It'll charge just fine. However one thing that mine did many times on either a 0.7 amp or 1.0 amp charger is it would charge to 100%, then it'd start draining and just wouldn't trigger to charge again. So I'd wake up and it'd be less than 100%. In some cases, really low if I started out almost full right before I went to bed. But it was random. Didn't do that early on and I think some days it'd work fine, and others, it wouldn't trigger to keep it topped off. I kept thinking I just hadn't put the plug in correctly, but after days and days of double checking that it was charging, I checked the battery graph. It hit 100% about 3AM, then just straight line decline to when I woke up.
I still slow charge during the day, but have a 2 amp charger next to the bed now.
Yeah my Nexus 5 did that too, I think its supposed to do that, it wont start charging again till it hits below 90% i think.

My 5X would just keep dropping though. So I'd wake up to 40% or 50% or something fairly low. That's no longer a problem with a 2 amp charger. But, since I have several different chargers and cables, I'll see if a different combo works all the time.
Ouch what do you all have running in the background? All the devices in my house charge on the same hubs at that same 0.36 amp, except for the wifes iphone which wont charge at anything less than 0.45 amps, but everything is at 100% in the morning when we wake up?
Just an update. I tried out a 0.7 amp charger last night with a nice fat USB cable and micro to C adapter. The phone was charged 100% in the morning. I'm thinking the fairly thin cable I used before was not passing through the full amperage.
