[Q] got a generic charger....it says-5v 500mah,original is 5v 1a(amper)is this ok?

it says- output :5v 500mah
the original says-output:5v 1a(amper i guess)
will this screw up the battery?

chances are no, considering it is half what htc recommends you charge it with, either it will charge it very slowly (half the current of the original) or the voltage wont provide enough to kick the phone into charging mode and nothing will happen (i.e. the charger "wont work")

Thanks for the help

It'll work, but as panyan said, it'll recharge much more inefficiently than with a 1 amp charger.

Actually... It will charge the phone exactly as charging via USB, as USB is limited to 0.5A.

Yep, it will charge your phone just fine @ USB charging speed, I have a similar charger.

And some of you forgot to mention that the phone will struggle when for example you will play games or use gps. Charge will be insufficient and instead charging it will slowly discharge while using it.

Well yes and no, in normal usage it will charge phone, but when you use your phone the way that you would drain the batty in two hours, then it will discharge.

Hey... Yeah if the charger is a car charger then it may not charge fast enough if using GPS software which can drain the battery fast. 1Amp reccomended for faster charging... other than that should charge fine but just slow like USB charging (which has a max of 500mA).
One question guys... I bought a car charger from ebay listed as for HTC phones. It looks like a cheap knock off product with a glowing blue HTC logo when used in the car. The device is rated at 2Amps. Now from what little I know about electronics I've been told that AC/DC Plug packs with more Amps are ok and the device just only uses what it needs. I'm not however familiar whith battery charing when you have a higher rated Amps charger... Would the battery on the phone just be greedy and "ask" for the full 2Amps? Would this then put strain or be dangerous by charging the phone too quickly?
Secondly while we are on the topic of electronics... I'm trying out a super cheap ebay battery supposedly rated at 1600mAH (I know these rating are usually fake). I've noticed the HTC battery is around 4.17V when fully charged. This battery charged up to 4.2V fully charged... Is that dangerous for the device?

2 amp is better, correct me if i am wrong. So the output is 5V and 2A, is that mean the power is 10W every hour ?

2 A charging current (if the phone takes in that much) will damage the battery in a long term use.

It is incredibly unlikely that the phone will discharge the battery faster than it charges unless you're doing something very wrong, e.g. Running a console emulator while downloading a large file over HSDPA with WiFi enabled (but not connected) and using GPS navigation with screen brightness at maximum!
Screen and background services take approx 150mAh, and I doubt radio will take much more than that combined. That puts drain 200mAh less than USB charging, 700mAh less than direct charging.
FYI: There's a spec for USB charging of mobile phones from supported USB ports which can pull up to 1500mA.

Hmm... not sure for Desire HD I haven't tested GPS with SatNav software using current widget... I do know that I'm pulling well over 200mA just with basic use at home with Wi-Fi on and GPS & Bluetooth off and I kill all backround apps. I do know that I've been in the car and seen TomTom app on my friend's jailbroken iPhone 3G (or 3Gs) and with the GPS on and not doing anything intensive... we were actually travelling down a long straight highway, the phone was chewing more battery than the car charger could charge, so he switched off GPS.
Ah also guys no need to worry about the 2Amp charger... It sh*t itself on the 3rd car use and no longer works at all. Junk! I also noticed on the 2nd car trip that opening Android SpareParts the charge is displayed as USB Charging not AC Charging so yeah I believe that the car charger was only a standard USB (max 500mA) power output and not 1Amp let alone 2Amps. Annoying how false advertising or labelling is part and parcel with cheap Chinese products.I was meaning to test the charger's output with Current Widget (which is what I'll do for my next car charger) but the charger crapped out and was useless before I got a chance.
One thing I did notice from looking at a log using Current Widget while charging my phone on the A/C charger in standby, the charge tapers off the power output the more the battery is charged. To get an accurate idea of if the car charger is going to be outputting 1Amp I'd be sure the phone battery is down to 40% (or in the 40s) then with all other stuff switched off I'd run a log on Current Widget and turn the screen off for a few minutes. You should have a reading of around +700 to +800mA if the car charger is rated at 1Amp.
Be wary of the cheap Asian knock of car chargers with the coil spring cord and the HTC logo that lights up blue.... Not worth the 3 or 4 bucks they sell on ebay for.

There's commonly those double USB cables for laptop hard drives so yeah I can see that if the USB ports are actually giving you the full rated maximum of 500mA you can get 1Amp output with this kind of cable but 1500mA?!? The only way I'd see possible for this is either you have a tripple USB cable connected to 3USB ports that are all outputting the full 500mA (and that's if a triple cable even exists or lets say you solder another one onto a double cable) or you have a USB AC/DC charger or some other USB port/hub you've rigged up which provides more than the USB standards of max 500mA per port. How else is this possible?!? Has the max power output of 500mA changed since USB 2.0 standards?

yeah there are usb 2.0 ports with more than 500mA power supply.
some companys give some extra juice to their (or often only one) usb ports.
for example: i've got an Dell Studio XPS 16 Notebook here. it has 3 usb ports, 2 with normal 500mA supply and one with 1A (for charging your phone, etc).

TBolt discharges while using in car as navi/pandora

When using in car, playing music from Pandora, and using google navigation phone uses more power than what charger can provide. Ive got it on a fast charger, so its supplying more current than a standard one,....its not overheating because when it does the charge light blinks green then red. Screen is on all the time during navigation and set at 30%. Anyone have same experience? My Droid X would keep charging in same situation. This is going down in charge %. I was using das bamf rom, just switched to Perfect Storm 1.2, maybe will make a difference?
Also when plugged in to power its underclocked to 768mhz.

Would switching kernals make a difference?

What is the amp output of your car charger? I'm pretty sure you need at least 1amp to feed this device while using GPS and data. maybe 750ma will do it, but most recent phones, tablets, mifi devices, etc. require at least 1a.

Same thing is happening to me, I dont think the charger puts out enough juice. I've ordered a verizon 2amp dual USB adapter, hopefully it will put out enough to charge the device.

Not sure of its output.
Let me know how the 2 amp works for you.

I use the one sold at the Verizon Corp stores and use Pandora daily with no issues when charging.. Chrages up if it was under 100 and stays at 100 when it gets there..

But I am using GPS with screen on the whole time, curious if you are too?

Turn your screen off. Navigation and Pandora will keep playing and your battery will slowly charge.

I guess your right,...it must be more of a power hog than my X was using the same charger.

I've used Last.fm streaming with GPS navigation and screen on for multiple hours at a time without any battery drain. I don't know what car charger I'm using (an unofficial one that I bought for my Moto Droid), but I've been running the Das Bamf kernels for the most part. Even before I installed any of those kernels I never noticed any battery drain while plugged.

Same problem here.
I have a Belkin micro-charge 1A. Can't use navigation and Pandora without losing charge. I had the same problem with the iPhone before I bought the 1A charger, the 500mah wasn't powerful enough.
And turning off the screen when you're in navigation mode defies the purpose.
Do you turn off the screen of your Garmin or Tomtom while navigating? I didn't think so...
Let us know if a 2A charger does help.
Thanks for the feedback.

I called Rocketfish to try and find out just how much powa the charger I posted earlier put out. They didnt know, lol. They said usually its posted in their system, but that one wasnt.
But, after thinking about it, I had the screen on 100% brightness because of glare I was getting. Will tone it down and went to utkanos kernal and see how that rides out.

You need to get a charger with more power. I got one made for an ipad. It has 2 USB ports. Made by scouche or something like that. Had this issue with multiple chargers even on my droids.

this is completely normal for other phones too, like the nexus one. using NAvigation with the car dock pulls more power than the charger can supply, so the phone slowly drops while charging. not much can be done about it. i bought a 1.3 amp car charger. helps a bit.

Skyrocket can't function as GPS Navigator?

This weekend I went on a trip and decided to try out using my Skyrocket as a GPS navigator using Google Navigation. I had my phone mounted and plugged in the whole time for about a 2 hour trip. The screen was on the whole time usually at high brightness (it would dim every once in a while.) When I removed my phone from the mount I noticed the power was down to the low 60's, which struck me as slightly odd since it was plugged into the charger the whole time. The next day I tried to use it as a GPS system again, but even as it was plugged in, this time I literally saw the battery gauge draining. When I turned off navigation and the screen the phone would finally start charging.
Is this a common thing or is there an issue with my phone or possibly my charger? Does doing all those things really drain the battery faster than it can charge it? One last note is that I was not in an LTE area during this, or at least not the whole time (I only noticed it was LTE at one time during the trip.) When I saw my battery draining in front of me I definitely was not in an LTE area.

Might be your charger. I'm having no problems using it as my primary driving, hiking and general outdoor GPS unit. When on car charger, it's charging faster then it drains.

I believe my charger is an old Motorola car charger that came with my wife's old dumbphone. It's actually not even a Micro-USB charger, but rather a Mini-USB with an adapter.
This may be a dumb question, but the actual charging port shouldn't be the issue right? I'm assuming those are always the same standard.

Check the car charger amperage output. I have an old car charger to USB that only puts out 750mA and another thats puts out 1A. Anything less than 1A with the navigation running (which means the screen and GPS stay on, of course), and it'll still drain the battery (and even at 1A it may still drain).
I've been putting off getting a powerful enough car charger myself. You'll need one that puts out 1-2A I would think. Most of the common ones off the shelf are 1A or less, and I've heard that some chargers reported max output is not as good as reported.

i second this...my phone won't even charge on some wall chargers, unless 700mAh or higher. let alone do any battery heavy functions like GPS. get something with at least 1a output

I'll try swapping the chargers. I have an overpriced AT&T one that I got for free that is collecting dust.

If the charger has 1A output then it should be OK

I'm having the same problem with my Skyrocket and cheapy charger that I bought at Fry's. Use the navigation with screen on and my battery is less than when I plugged it in.
Going to buy this combo 2A and 1A charger.

When I was looking for a more powerful option, I saw that one on Amazon as well. My only hesitation at buying it was why it was so much cheaper than all comparable options at local stores, or even online...I've heard that the cheapie chargers may not actually output what they say...though for $4 plus shipping, I guess it's not much of a gamble. Let us know how it performs!
P.S.-Pulled up the reviews...not too many positive ones (though 1 or 2 were good): http://www.amazon.com/GTMax-2-Port-...iewpoints=1&sortBy=bySubmissionDateDescending

Its actually more than just the charger output that is a problem. If the center two pins on the USB connection aren't shorted, the phone will treat it as a USB connection to a computer, not an AC connection from the wall, and only draw a max 500mah. I had bought a 1amp and 2 amp charger for my car and would get the same results as the 500. I started to think it was my car limiting my output!
But I then found an article detailing this problem that I've since lost the link to, but the method worked. Pop open the charger and solder the 2 middle connectors together and all is good.
I don't know why the charger manufacturers don't know this... Or maybe this phone is doing something new? Maybe someone makes a USB-> micro USB with the center pair shorted in cable?

Just Google "Solder USB Car Charger" and you'll find plenty of tutorials about how to do that. Personally I'd rather just buy one that out of the box works.

Tried out my AT&T charger (which can be found here) and it worked perfectly. Set up the GPS and everything and now it will charge even while doing all that stuff. Thanks for the help

I have the same issue with my SkyRocket. LTE makes no difference. If I'm using Google Navigation or Waze and the Screen is on my charger/phone can't keep up with the battery drain. If I turn the screen off and keep the GPS app running the battery either doesn't drain or doesn't drain as fast.
I've checked my car charger and it's one of those dual usb ones, with a 1 amp port and a 2.1 amp port. It has no indication of which port is which, so I don't know what port I'm using at any particular time. I've tried both and the effects are the same.
Regardless, when the phone is plugged in to that charger the phone reports that it's an AC charger. Supposedly that means I'm getting at least 1 amp, right? So why is 1 amp not enough?
I don't like the car charger you guys suggested because it has the curly cord. I'd rather use a car charger that doesn't come with a cable so I can plug in my own usb cable.
Any suggestions?

Discharging while using Navigation

Hey Guys,
So I was recently on a trip this weekend and was using Navigation on my Nexus 5 for a 4 hour drive. I had noticed though after a short while that while I had my Nexus 5 plugged into a charger it was still continuing to drain battery.
With my Galaxy Nexus in the past I was able to run Navigation / Music / Etc.. all whilst still charging so it came as a disappointment when I saw this.
I made sure that I was charging on (AC) mode and it still continued to fall, albeit a little slower than (USB) mode though. When I went to the battery usage navigation had taken up about 59% of the battery drain, I was surprised because I though it would have been the screen but that was only like 14% of the battery drain.
Anyone else run into this issue?

Check the Amp output on the charger. Anything less than 1A will not charge the phone while in use.
I had the exact opposite issue with my G-Nex, the "rapid" charger I was using only output 550mAh as opposed to the 1A that is required to charge while in use. I don't believe it is an issue with the phone, it's probably just the charger. $10 to $20 will get you a nice, reliable one with the proper output, and possibly an additional USB port.
Hopefully this helps

Don't buy cheap car chargers, just not enough power. I use a Verizon car charger that has an extra USB port for charging another device and it charges while the device is in use.

Thanks for the input guys, unfortunately the charger was 1 amp that I was using. I do have another car charger that I use and none of them are the cheap USB ones. I guess I'll have to do some more testing with the other car charger that I have.
I was just mainly concerned, not if there was something wrong with the phone, but with the fact that even when charging in AC it wouldn't keep up with navigation's wear on the battery usage.

Thought I would update to confirm that my Galaxy Nexus car dock charger charged it extremely well after testing while navigating.
Definitely was the other one I was using.

When you switched chargers did you happen to also use a different cable? I couldn't get any of three different chargers that I tried to keep up with the GPS battery drain. Then I realized I was using the same cable with all 3 chargers. The problem was that the cable kept the phone in DC charging mode at nothing more than 0.5 amps. I bought this fast charging cable on Amazon and now I actually gain battery percentage even while using my GPS full time.

I had exactly the same thing with my old phone and discovered it was the cable not letting more than 380 ma pass through it.
There are apps like this https://play.google.com/store/apps/details?id=ccc71.bmw that let you monitor mah in and out etc so you can test out different leads and chargers

Nexus 5 not charging properly (?)

While I'm using my phone it keeps discharging. Screen is on minimum brightness, all apps closed, charging with original charger. Stock ROM, same happens with franco and ElementalX kernels. Haven't tried with stock ROM, but that would probably be even worse. Is there an app to check my charger, IE an app that would show charging amperage or something? Thanks
EDIT: The beggining of the post sounds so dumb What I wanted to say is that the phone keeps discharging while charging and using it at the same time. I'll just leave original text like this, it may make some people laugh

well, it depends what you are doing. if its discharging while using and you are only reading a web page, then its not supposed to. but if you are charging and using, and its discharging while you are gaming, thats normal. also it would matter if you are charging it via ac or usb(check how your phone shows the connection). if usb, than it discharging while using is very normal.

Just browsing on 3G. Sometimes listening to music too. It discharges even faster if I'm listening music with my headphones too. All I'm using is chrome beta or Flow for reddit. I'm using xposed, all location and wifi scanning **** turned is off...

right, but does your phone tell you its connected usb or ac? usb has a much lessor charge, and using it while its charging usb can easily drain the battery. oh, and xposed comes with a multitude of undocumented issues. most probably wont affect you, but some possibly can, the modules.

AC. I know about all these things, it's just that my discharge rate while charging seems not to be normal. It is 1.2 A charger, but it isn't behaving like one... Or am I just not used to nexus and that thing is totally normal?

It would be nice if google sold those in my country... Funny thing is that my ~10$ dual usb car charger charges my phone 2x times better than this ”original” one.

The stock charger should be able to keep up with heavy usage, let alone basic web browsing. I can play intensive 3D games and still get a trickle charge. Something is wrong with either your charger or the device. The tricky thing is that all the current meter apps measure current by checking the net current on the battery... which means you're obviously going to have a negative current since your phone is discharging. The only accurate way is to get a USB ammeter. Do you have another charger from an old phone you can try? That would be my first step here.

sounds like the charger might be going bad, they can go bad fairly quickly, and often. try a different charger as said above.

UPDATE:
Original charger is ****. Overnight it charged my phone to 88%. No wakelocks, no sync, just wifi. When I woke up, it discharged to ~70s. Then I said f this ****, plugged my old 0.5 A charger and it charged my phone faster with screen on than the original one on deep sleep. I don't like this.
