Woke up to a [possibly] bricked Atrix :(

Yup. Left phone on charger overnight - woke up and the camera was flashing every 2 seconds. That's all it will do. Whether it's hooked up, unhooked. As long as the battery's in that's what it does. No rom changes in over 2 weeks. No damage of any sort.... no recovery or anything

Well you can probably do a warranty exchange.
I voided my warranty and your mum.

I had something similar with my nexus one. Except it wasnt the camera but the trackball... changing kernels around seem to help a bit but eventually i took it for water damage. Take the battery out and let it dry off for a day or two. You can also try to pry it open and have your hand at any corrosion if you find any. However i wouldnt recommend that unless you know what yer doing.

He said it was left on the charger, not fell in water.
I'd crap my pants if this happened to me.

I realize that but like i said i had the same experience and my phone didnt get noticably wet at any time could have been a single drop of water and corrosion takes a while to build up.
Still...
Im wondering if you used your original charger when this happend because i can personally say ive seen my atrix behaving strange when connected to some cheap random charger (touch screen not working for example). Didnt believe it could cause permenant damage though.

It was hooked up with a Blackberry charger, actually.
Still acts the same.

Check the charger to see if its power ratings are different than your otiginal one.
Also... does the device boot up in any way or is the screen simply black and the flash flickering no matter what?

Looking at it today, I noticed that the charger port (or inlet if you will) is very structurally loose. The voltage on the blackberry charger is about 3/5 that of the stock Atrix charger, if memory serves me - somebody at work switched out the chargers the day after I got the phone. It took a good 6 hours to charge...
ATT said that it would be full cost of phone, because it's personal damage.
I'm looking into the Mi-One.
EDIT: No, the screen will not even begin to come on. Camera flashing is the only indicator of any power. Used an external battery charger, and two different batteries.

The MI-One looks sweet!!!!

Moto will probably either fix it or send you another phone. I know people who bricked from trying to downgrade and they got another phone. I'm sure you could too. I would try that before you buy another phone.
ETA: Now that I think about it not being able to put the rom back to stock would probably be an issue if they can get it to turn on but if they can't they might replace it.

I also think you should bring it up with motorola. Waking up to find your phone bricked is hardly what id call personal damage. You also shouldn't bring up the charger issue. And as for the usb port i'd say it would take too much effort to discern the connection with that and the phone acting as it is, and im sure they would rather just send a replacement unit.
A usb port malfunctioning is hardly an account for personal damage. The usual case is they simply stop working, but definitely not brick your entire phone.

[Q] Can I damage the battery using a lower amperage?

I have a ton of Samsung and HTC chargers from all the phones I've had over the years. Enough that I have these chargers placed throughout the house in any place I may need to charge a phone or device, and travel with the HTC/Samsung chargers.
I noticed the HTC and Samsung chargers put out 5V at 1.0A, however the LG charger that came with the phone puts out 5V at 1.2A. If I use the existing chargers putting out 1.0A, can I damage or lessen the life of the battery in my new Sexy Nexy?

It won't damage your battery, it is actually better to charge it with the weaker charger but it will take longer to fully charge

No, the phone will take what it needs. It doesn't take full whack constantly, it depends how depleted the battery is. Anything with an output lower than 0.8A and you'll probably notice longer charging times. That's it

On many devices, using a low capacity (or poor quality) charger can create some touch screen issues with responsiveness. It does not damage anything, but makes interacting with the phone problematic.

Hi,
What about if I charge my LG nexus 5, which comes with a 5V 1.2A charger, using a Samsung Galaxy S charger (5V 0.7A)? I know it would take longer, but would it ruin the battery?

I have the original charger, HTC desire, HTC one s, some old windows phone lg charger, Samsung wave 2 charger and a generic HTC charger in my car. Never had any problems with any of them on any device. The only thing I notice is the car charger charges slower then the others.

The technical details behind this is that having a low amperage charger connected causes the digitizer of the phone to take less electrical current, because the battery will be taking most of it, so it will do this chaotic thing, especially when you put two fingers on a horizontal position and swipe up or down. That's also because of some static electricity problem caused by having an electrical flow from the wires to the battery which makes the digitizer lost.
So, this:

is probably the other way around, since you need a bigger amperage to properly use the phone.

There is absolutely no way lower amperage in any circumstances can damage any circuitry of any sort.
The amperage is simply the amount of energy that is being sent into the phone. Less energy = Slower charge time.
If you give too little amperage to a computer, for example, It will simply not turn on, or if it does turn on, randomly turn off.

Yeeeah. Randomly turn off because of not enough electricity. That's not damaging. At most it could damage software if the filesystem on the computer is non-journaled. Maybe corrupt a file if something is being written.

[Q] Battery Preservation

Dear L2 G2 owners,
I really love my battery on my LG G2 and since its not removable i want to do the best to preserve its lifespan.
So what i'm doing is, plugging in my phone to the charger when i get home and leave it there even after its been completely charged.
Is that correct or should i leave the battery to complete its cycle then charge it when its almost empty.
What other tips would you suggest.
Cheers!

From what ive read thats exactly how youll reduce your batterys life span
Sent from my LG-D802 using xda app-developers app

The more cycles, the shorter the life span. The thing that will destroy the most is heat. These are good batteries, trickle won't do much, heat is the worst. Don't worry so much about it. Nothing you do is going to have much of a noticeable impact.

Thanks a lot for the info guys!

Btw, these batteries are indeed replaceable. Just not in a normal way, and more difficult than say a MAXX. The back cover does come off. Just a thin plastic back that can be removed going clockwise from SIM tray.

I've done a little research on batteries from such places as Battery University, and learned a few things that might be interesting. I haven't posted enough to post links, but the location after batteryuniversity dot com is "learn/article/charging_lithium_ion_batteries" if anyone wants more information.
It seems that Li-Ion and Li-Polymer batteries are treated essentially the same; the difference is mainly in the packaging. As for charging, they do better if not charged 100%, and never discharged 100%. But one thing they say, which I was told by the salesman when I bought it (but didn't believe him at the time) is that they should not be charged while power is on. The charger is designed to trickle charge the battery, coming on at a certain voltage. But when under power, this cycle happens too often and stresses the battery too much. I suppose it might be OK to charge it while on if you watch it, and remove the cable when it gets to full charge or just under that. I suppose a timer would be ideal.
I just wish I knew how much difference it actually makes, since turning it off means you can't receive calls. I've had devices with Lithium batteries in the past that were left on a charger all night, and the batteries seemed to last for several years, which is probably longer than my phone really needs to last.

I still think its funny that people don't think that there isn't any charging logic in the phone and that it just willfully commits battery suicide if the user doesn't micromanage charging.
Back in the day, early battery tech such as NiCad was extremely sensitive to temperature and the chargers weren't designed with intelligence so they destroyed batteries with 'Fast' charging by overheating. Also, if you never let the battery discharge completely, the battery would start to form cadmium crystals and lower the apparent capacity of the battery. So, slow and deep cycles were the proper way to go. NiMH batteries were far superior and intelligent chargers were introduced but could still suffer the same symptoms of over heating with cheap chargers.
The idea that you can only trickle charge Lithium Ion/Polymer batteries is laughable. The rate of charge is controlled based on the temperature of the battery, if it heats up, the charging circuit clamps the current down, if it is cold it ramps it up. Also, contrary to wisdom applied to NiCad, deep discharges and full charges are harder on Lithium batteries than the earlier tech. In the mid ranges of charge the charger will go all out, when it reaches the top end it slows down to a trickle because the battery is more sensitive to stress at those charge levels. Conversely, if the battery is fully discharged, the charging circuit will start out with a trickle and speed up as the level increases.
On the G2, if there is high resistance across the data pins it stays in slow charge mode, most likely to protect USB ports not meant for charging, if there is low/no resistance it goes into fast charge mode, it thinks it must be connected a dedicated charger. If the charger or the cable gives the wrong setting to the phone the user is left scratching their head.
Luckily the AT&T car charger I bought with my Galaxy SIII works properly with my G2. Sadly the correct cable with my laptop, even with Lenovo's dedicated charging port, it stays in slow charge mode because it senses a data connection.
Edit: Also, the comment about not charging while the phone is on is another hold over from the NiCad days. Lithium technology could care less as all phones have regulated charging circuits now.

Anyone tried wireless charging ?

Anyone tried wireless charging on DT2 or MXF ? And how was the experience ?

Works, nothing special - overnight charge from 1% to 100%

It works, but many of us have problems with the Qi charger disconnecting charge at 100% and then reconnecting after about 5% has drained. Motorola is looking into it. I may be picky on which Qi charger you use.

Maybe I did not notice this problem - as I put the phone on charge in the evening, until the next morning I take it to work.
I use cheap qi charger from ebay - ~$2.5

Use a ravpower qi charger every night, no issues, phone comes off 100% full, cool to the touch. I know some units I've tried with my Maxx back in the day kept it warm through charging.

Exactly how it should work to prolong battery life. Keeping any battery (especially lithium) full charger for long period of time will significantly decrease its capacity.

Never had a problem with that in the past even with wired chargers. I don't think in recent phones that there is actual current on the battery at all times past 100% whether charging wirelessly or wired. I'm pretty sure it goes into a maintenance mode, but it will still show charging on the display which is the important part. That is important if you use it on your nightstand as an alarm clock with wireless charging. My Sony Z3v had no problems staying in a charge state even after 100% but my Turbo 2 does not which causes it to disconnect. It will reconnect after it loses about 5%. If I don't have it silenced, it will wake me up when it reconnects. It also affects any tasks you have programmed to happen when it is charging.
From my understanding, the first Turbo did not have this problem. I think it cropped up from the inclusion of the powermat charging or maybe something related to the 810 processor. Anyway, just waiting for a definitive answer from Moto.

Have any Qi charger brand to propose ?

I'm using a Samsung Qi puck - not the newer round plastic one, but the older more squared soft-touch one. Works great, I don't have the 100% disconnect issue.

I use the tylt qi charger the desk top one so my phone is sitting at a 60 degree angle. It works great no issues and every morning my phone is at 100% and cool to the touch

This all sounds encouraging. I think it would be helpful if people could also add a few common notes:
charger / model
any case they have on the phone (or not) when using a Qi charger
whether the phone must be in a certain orientation (e.g., horizontal vs vertical) to charge
whether the phone is at 100% - and stays there after a charge
whether the phone is cool / warm / hot once charged
A cleaned up list developed from this would be a good resource for the user community

Tylt works great phone gets warm. Itian charger is cheap from Amazon but is very finicky.

Uhm, that's one of the sillier things I've read today.
If it drains to 5% it's not terribly useful as a charge system regardless.
A charge controller chip is supposed to be designed to PREVENT the problem you just described.
Each charge cycle, regardless of it's form shortens the life of the battery, period. If you charge it up and then let it deplete it like that, you're damaging it as much as if you left it charging.
You kind of need to leave the stupid thing plugged in or in some wireless charge hysteresis loop so that the device isn't drained. In light of the charge system being supposed to keep the battery out of the loop until it needs to charge it again (some threshold below 100%) it shouldn't MATTER if it's "plugged in" and the device won't be pulling from the battery.

http://batteryuniversity.com/learn/article/lithium_based_batteries

I picked up 3 Samsung qi chargers at 6 quid each on offer on Amazon (UK). They work very well although they are more a convenience thing rather than a method of charging. I use one at work. One in the bedroom and one next to the Xbox great for the work desk to keep the device topped up and frees you up from plugging and unplugging constantly BUT.... It takes absolutely ages to charge so you dont go expecting to be dumping your cabled chargers. I use the work one most of the time as I'm out and about a lot and its very useful to be able to just grab the phone without unplugging and placing back on the pad when at the desk. The turbo charger gets used at home more coz in more likely to plug in to that and jump in the shower knowing that I'll have a nice reserve of power for the pub so yes they work as advertised and work well great as a trickle charge device when you ain't in a rush. If anyone is interested ping me and I'll spend some time on giving more detailed stats such as charge times from 0% and model number of the devices I use. Away for work at the mo so probably the weekend

Raynic
I bought the Raynic Orchard I. It charges the phone just fine, but I noticed that if the phone wants to wake up because it senses movement, it detaches and reattaches to the charter, which gets very annoying. I moved the phone to an angle where it couldn't see me (but I could see it; sensors were under my monitor stand but the rest of the phone was sticking out) and everything went smoothly after that.

Verizon QI charge stand, Verizon case, have to charge upside down
To charge our new Turbo Droid 2 in a Verizon QI stand with the Verizon case on it, the phone must be upside down. It's OK if out of the case. We have a car QI 'base' which it won't charge in either; probably exact same issue, whatever that is. Any ideas appreciated!

Is it bad to charge overnight

Hi All
Is it bad to leave the note 4 plugged in charging all night?
Does it damage any components?
All help would be greatly appreciated.

No. It should not damage your phone. I did this with Note3 for 2 years - and it is stil OK (gave it to my mom). Now Im doing this with N4 without any problems.
cheers

the power from charger never cuts off completely it will keep drawing some power to keep the phone charged at 100% so yeah charging overnight does damage your battery by keeping it charged constantly.

It will definitely not damage the battery ... smart phone batteries are intelligent enough to stop charging when its 100% .. thats what I think .. it will not damage ur battery
Sent From My Precious Galaxy Note 4

It will stop at 100% then let it drop to say 97% and charge back to 100% repeating the cycle. Let it do its job and just charge it overnight. You have a phone with a removable battery. Just replace it in a year if you have to for $20.
