Any of you guys ever use the Google Navigation w/ N1, while plugged in to the car charger and find that it's still discharging even if it has the charging icon? Like the charging rate is less than the discharge rate.
I've used it in the car for hours, must be plugged in for me, otherwise it would be dead very soon. Mine gets hot as hell with the gps on while plugged in and driving looking at the screen.
I bet it's possible to achieve a negative rate of charge with enough stuff going on inside the phone.
I like it better than the tom tom though.
I have experienced this. I got to work and, despite having been on charge all the way there, my battery had depleted. 100% to around 85% on a 40 minute journey.
However my car cigarette lighter socket is extremely temperamental, and so it frequently looses connection. In the case of my N1 I was hoping this was the problem, rather than the phone. I can have the car repaired!
I have had phones in the past when it was possible to achieve a negative rate of charge (Samsung Omnia using internal GPS and HTC Wizard using bluethooth GPS). Particularly fun was the fact that the Wizard won't charge from a car charger when it gets too low. This left me STRANDED in the middle of the US.
Navigate uses alot of juice because of the GPS.
The phone can only charge so fast. If the usage is faster than the charging rate then obviously you'll get a slower charge or a depletion.
It's most likely your car charger. It is probably only pulling a small amount of power. There are some 1000ma car chargers you can buy that should work better.
I also believe the official car dock from Google will keep it charged too.
It definitely depends on the car charger and your settings.
My first car charger supplied 500mA (I had it lying around from some other piece of equipment I had bought). I did an experiment with the screen at 100%, navigating, and streaming Pandora. I lost something like 15% of the charge in 45 minutes or so.
I now have a 1000mA charger (just a couple of bucks at monoprice.com). What that same configuration, the battery goes down very, very slowly. If I don't run the screen at 100%, or if I turn off the screen during long stretches between turns on the highway, the Nexus One gains charge instead of losing it.

go plug your nexus into the car charger and go to settings, about, and see if it shows usb or ac and you will figure out the problem. it prob will say usb which means its only pulling 500 ma rather than the full 1000 ma that it should be. my car charger pulls the full amount and it can actually charge the device during navigation.

We have many m5000 / Universals and they are so slow to charge and the battery life is terrible.
so this is not a one off. It takes hours...
The device takes forever to charge regardless of using charger, usb2pc charger or even car charger and if you make a phone whilst on charge- for instance on the car charger... if I make a call even whilst its on charge or use my tomtomsat nav - theres a high chance it will run out of power before the journey ends.
Anyone else had this issue.
USB is a slow charge. Don't know about the car. Mains charger does not seem much longer than most modern devices. Battery life will suffer if you don't close PIE after use.
I can't remember if this has been happening before, but when I have the HD2 conncted to a computer it takes forever to charge. Maybe 1 % per 10 or 15 minutes! Charging on the regular charger is so many times faster. Mybe 1 % per minute or so. This can't be right, can it? I have the same problem on my HD2 and my wife's HD2. They both are using the same ROM (ironically it's the Energy Max Sense ROM...). Is it possible that the ROm is the culprit? They both have quite new original batteries.
USB port supplies less than half the "oomph" of the wall charger. USB charging will run about 300mAh while wall charger will supply about 800mAh
Also, older PC power supplies and older USB 1 sockets may provide even less, depending on what other devices are in/on your machine drawing power.
Yes, thanks. I know that. But that shouldn't accord for an at least 10 time slower charge. And I know that they weren't like this before, but I can't remember how long before. And I have no idea if it can be the radio ROM, the regular ROM or what.
I use energy ROM but older 23699 & see no issues on USB charge rate but yours does seem rather long, what status is the device in when USB connected & is screen off !
Also, keep in mind that the rate of charging goes down as the battery level approaches 100%. So maybe u r comparing charging rates measured over different regions of the curve, i.e. observing the rate with usb charging when the battery is around 90% will be drastically different from the reading observed with wall charging when the battery is at 10%.

if youre running windows 6.5 the quickest way is to turn the phone off then charge
or get a cheap chinese battery charger 6 dollars and a spare chinese battery extended around 10 bucks with 2400 mah double the juice i got a couple of those i never charge my phone anymore lol
Mister B, I have tried with the phone both on and off. But I really need to keep the phone on because I get a lot of work mail and SMS that I need to keep an eye on. Also I don't think I had problems with earlier versions of Energy, I may have to try to go back and see if it's the ROM.
ASCIIker, no. The problem isn't the final bit of the charge. If I put it in when it's around 30 % it almost won't charge at all. If anything it looks like the phone is getting a better charge when it's close to 100 %.
Casemandan, I have a charger like that you describe, but I do a lot of driving with TomTom, and even though I did change battery on the run yesterday it's not something I would recommend...
Btw I have the same problem in the car, with a combined charger/battery charger cradle that I have put there. The red/orange charging light is on, but it goes slowly down instead of charging. But I'm wondering if that is because the car charger is connected to a mini USB in the cradle, not to the micro USB. I have to try that.
I don't have mine connected for much time via USB to PC but when do & have left on charge rate seems acceptable, could be ROM as I found a few issues with newer builds.
As for car charger the low rate will be down to the power adaptor unit being recognised as USB charge not AC charge.
If the Power adaptor you are using can feed 800mA<>1000mA then modding it by bridging data leads so handset goes to AC charging rate is the way forward. Use tbattery to see what current charge mode is.
You may be able to buy car charger already set for AC charge (have a browse in HD2 accessories forum) but I use an old USB 1000mA Ericsson adaptor I bridged for AC charge mode.
Like you say testing charge direct in car is a good idea as many of the phone/battery charger cradles output pathetic charge current.
Well, it's not the ROM. I tried an original ROM and had the same problems. I need to see if there is something wrong with my cradle. I do have a charger that should do what you describe, but when it's plugged into the cradle in the car it doesn't. I'll try to connect it to the micro USB instead of the mini USB and see if that matters.
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
I tried googling this but could not find anything. Does anyone know the power needed to keep the Turbo 2 from having the battery drained when running with the screen on full time?
With my Turbo 1 I was using an older Blackberry wall plug in my Jeep's power outlet and that was good enough to keep the phone at the same battery level while running Waze(as in, no battery drain, but also not charging).
With the Turbo 2 it is slowly draining using the same wall power supply.
I was wondering if anyone knew the minimum power I would need to keep the screen up 100% of the time, like when running Waze? It can be any form of power supply since I have a plug in outlet in the Jeep, as well as cigarette outlets and USB.
I could easily use the charger that came with it, but it pulls 25w which is a little much and can cause car battery issues over the long run, which I am trying to prevent.
I use charger for cigarette outlet with 1 A output. If screen is off, charges phone. If is on, keeps on the same level or charges slowly. Real amperage depends of the usage, screen brightness, etc. Of course, you can always use ammeter and measure exact current in the specific condition.
You can Buy the motorola turbo charger for car. I bought the moto X Force here in Best Buy México, and it came for free. Maybe it can solve your problem.
Hello everybody, I have got a wireless in car charging dock and when the phone is in use for example when using satellite navigation or whilst I have Pokemon go on the screen and the screen lit up, the phone discharges. It is charging but at a slower rate than it would be if it wasn't on screen on. I have tried three charging docks and four in car chargers including quick charge chargers and just standard two amp chargers and it still has exactly the same effect. It always seems to charge fine for the first 4 or 5 minutes but then after it takes down to an average use of minus 100 - 200 milliamps. I assume there is a restriction on the phone to reduce heat or something and the only option I have when using the phone whilst in the car, not physically using but rather using the phone to display sat nav etc is to use a cable rather than wireless charging?
It frustrates me that it charges correctly to start with, but then it gets to the point where it is discharging rather than charging. It is much more convenient than having to keep unplugging and plugging in the phone
