I used my car tom tom charger to charge my tp2.
It was only once for about 20 mins. When I checked it the output was 5v dc 2amp.
I read the tp2 battery can take 1.5amp max.
Would this have been likely to damage the battery? Since then I have been thinking the battery doesn't last quite as long as it did.
I think your safe. I use a Motorola charger on my TP2 and it works fine. It also is 5v/2amp's. I am sure some other members will chime in soon...Tj
general info on AC adapters:
voltage is what you should be most concerned about on the charger, voltage MUST match.
amperage is secondary, you need an adapter than can source AT LEAST the current that your device needs. ie, your charger is rated for 2amps, the TP2 rated for 1.5amps, then you will be drawing 1.5amps. if your charger was 1amp, and the TP2 needs 1.5amp, you are short 0.5amps. For charging, this probably won't be a problem, you'd just charge slower. But for something that needs an AC adapter to run off of, you might have problems.
i charge my phone with anything with a mini usb plug, don't think it matters
ace.app couldn't said it better!
So @testaccount: You can face probs with your charger.
I had a charger that could only provide 1Amp, and the TyTNII and the TP2 stopped loading after 10-15min.
With the original HTC CC C100 which provides 2Amp's no problem.
Anyway the amount of Amps will never kill your device, as long as the voltage is right.
thanks for the replies.
i can stop sweating now.

So if USB only provides 0.5A does that mean you can't use it to charge the TP2?
It will simply charge slower @ 0.5A than @ 1.5A. If charger is more than 1.5A than TP2 will still only draw 1.5A

Did anyone find an answer to the issue of the Desire losing battery power even while being charged in the car while using co pilot? Or any sat nav?
I'm charging via genuine HTC cables and charger etc but still the Desire loses battery power if it is using a sat nav application. So my question is, even if it were plugged into a higher powered cable and charger would the result be the same due to the heat being generated by the 1ghz processor or is there an after market charger (for the car) that will maintain the battery or even charge it when sat nav is in use? thanks for any help/suggestions
Check your charger ...
It should output 1000 mA.
There is charger that output only 500 mA, and this will give you the above problem.
Thanks gogol for this reply. My htc usb charger plug is an older one though the cable is brand new (came with the phone) so you will most likely be correct with the suggestion that my charger is only delivering 500mA. I cannot check it as it does not say on it anywhere what it delivers which seems to be the case on most of these things, they dont actually specify the charge they can deliver. Are you aware of a brand/model that will deliver a full 1000mA charge to my desire? Thanks again for any help.
Hi,
I've lost my charger, and I don't know if I can charge it with a charger with 5v - 1A or not, what I do know is that charging with USB is 5v - 500mA.
What's the power of the SE Arc original charger?
On the charger it says output 5V 1A
Is that what your looking for
It's Exactelly what I'm looking for thank you very much
The original SE charger for the arc is the GreenHeart charger EP800. It has got an output of 5V; 850mA.
As far as I know, there's no SE charger with an output of 1A. I've seen chargers with 500mA, 700mA and the 850mA.
My charger got fried during a power surge while holidaying in India so after asking around on the forum, I bought a Nokia AC-10N charger with an output of 5V, 1200mA. I've been using it without any problems. Pretty happy with it. Charges the phone much faster.
Thank you, that helps very much, but I heared charging the phone with higher voltage or higher Amperage can charge it faster, but it lowers the battery life on the long terme, it's appreciated to charge it with lower power in order to preserve battery life

Totally true on all counts. You can really use ANY usb charger to charge your Arc, but the higher the mA the faster it will charge. And the higher the mA, the less overall life your battery will have. If it's normally supposed to be good for 5000 recharges, it might drop to 4000 recharges (just numbers pulled out of thin air).
The "Normal" standard for USB power is 0.5A (or 500mA). The iPad for example uses 1.0A, or twice as much as standard. Now in the iPad's case, it refuses to charge with anything less. I don't know if that's true for the Arc or not...if so, and the SE charger is rated at 850mA, then that's probably as low as you'd want to go just to be on the safe side.
Personally, I'm willing to use the iPad's charger and charge a bit faster for a bit lower useful battery lifetime. A new battery I can buy....time spent waiting for my phone to be charged I can't get back
The amperage rating on a charger defines the maximum current the charger is capable of supplying. A 1A charger doesnt force 1A down the throat of whatever's connected to it, if you connect something can only manage to pull a maximum of 500mA then it will only get 500mA.
Consumer power supplies are generally constant voltage. E.g. a 5V charger will supply 5V to anything connected to it. The amount of current that the device will draw at 5V is the amount it was designed to draw, up to the limit that the charger can supply. If the charger cant supply enough, generally you just get slower charging (though some poorly designed devices will just refuse to charge at all). What *will* tend to destroy your device quickly is a voltage mismatch, e.g. connecting a 5V phone to a 12V charger.
You can get constant current power supplies. These ramp up the voltage in order to force the required current out regardless of what's attached to it (even if that's a human being). They are scary.

Exactelly what I was thinking, thanks.
Now I think I can charge my Arc with 1A without any problem, since it's gonna take only 850 mA from it
Hi
watch this video to get all info about the Optimus G battery

Nice tech. I liked the way they managed cpu activities besides all.
My question is that why it takes around 2:30 to charge the phone fully?
According to this: http://www.qualcomm.com/media/blog/...-charge-10-less-time-charging-more-time-doing
OG benefits from Quick charge 1.0 which should boost charging process. Is it boosted by default? Is 2:30 fast enough for a 2100 mAh battery? or it's something kernel related and should be enabled?
2:45-3:00 its the charging time and its just fine.
You can always use a bigger charger and ruin your battery faster. Or explode..

I don't want to ruin my battery bro. I'm just curious to know if other phones with the almost same specifications have similar charging time or not. I mean is this normal or not? Do you know about nexus 4 charging time? or xperia zr? these all have quick charge 1.0 while snapdragon 800 offers quick charge 2.0 and that's why phones like G2 having a battery with more capacity have under 2 hours charging time.

Well... Unless you use a charger that sets a current (extremely unlikely), it won't matter a single bit. Just a simple physics... All standard chargers provide stabilized voltage within certain current limits (that's your charger's Amp rating). The phone's battery charging circuit determines the current it draws from a charger. So, even if your bad-ass charger is capable of providing 10A output, your phone will not draw more than it needs when charging, which is about 1A (sorry, I don't know the exact charging current of the OG).

the charging current of OG is 1.2. So, you mean the phone won't be charged faster if one uses a higher voltage charger?

If you use a higher voltage charger, you could simply fry your phone -- depends on the actual voltage. The protection circuit may simply shut off the input, or limit the voltage at 5V -- I don't know enough about the OG's schematics. But it should still limit the current at the value it's designed for. Anyway, I wouldn't experiment with that... But if you are talking about higher Amp-rated charger with 5V output, then it won't charge faster, unless the lower-rated charger is actually rated lower than the phone would take. Here, just a couple of examples, assuming 1.2A nominal charging current...
Example #1: 0.7A charger. The phone is trying to suck as much as it needs, but the charger can only supply 700mA. So, it will charge slowly.
Example #2: Stock 1.2A charger. The charger is supplying just what the phone needs, which is 1.2A. So, it will charge faster.
Example #3: 2A charger (or more). The phone will still draw 1.2A, even though the charger is capable of supplying more. So, it will charge at the same speed as with 1.2A charger.
Makes sense?

Oh, I see. Thanks. But, I don't know about the schematics either. I don't know if the phone has this smartness to draw as much as it needs or just draws as much as given. So, I won't risk either.

Regardless of particular schematics, a properly designed charging circuit is always drawing the set current from a source. In other words, your phone is definitely smart enough to only take what it needs. Basically, "as much as given" in this context is incorrect statement... A charger "gives" a specific voltage (5VDC for USB-charged devices), and the device "takes" a specific current. So, no matter what the Amp rating of a charger is, it will only give as much juice (Amps) as the device decides to take (within a charger's Amp limit). If a charger can't provide enough current for the device, then you have a problem with slow charge, or no charge at all. But higher Amp-rated chargers are fine. If you have, let's say, a charger from a tablet rated at 2.5A, or a stabilized lab power supply rated at 20A, both of them would be OK to use for charging your OG. The only possible problem in this case could be a defective charging circuit in the phone, which might not limit the current the way it's designed to, and could draw enough from a high-powered charger to kill itself. Low-powered charger would simply not be able to provide a dangerous current, if that happens...
Having said that, I've got quite a zoo of various power supplies laying around, and I used all kinds of them rated up to 30Amp to charge different devices. Never had any problems.

and you've never seen any acceleration in charging time? So, it's just a common mistake that people say higher Amp-rated charger results in faster charge?
E977 battery difference?!
look at these two screenshots. one of them is E977 (in Spanish) and the battery is written to be SiO Lithium-ion. (SiO+ is used in G2)
the other is for E975 and the battery is written to be Lithium-Polymer.
Are these two the same?! Or this is an improvement made in hardware revision 1.2?

As I said before, it really depends what exact Amp ratings you are comparing... If a charger is rated lower that a phone's charging circuit, it will certainly underperform, and will charge slowly. But if your charger's rating matches or exceeds the charging current required by phone, then it makes no difference.
I personally don't have an OG stock charger, so I don't have any experience using a charger rated specifically at 1.2A. I only have USB chargers rated at 700mA, 850mA, 1A and 2A. Plus, an assortment of other power supplies rated anywhere from 2A to 30A. Of course, I do see a faster charging when going from 700mA charger to 1A, and then to 2A, because the first two are under-rated compared to the phone's specs. However, once I go with 2A or the higher rated power sources, there's no difference at all.
Hope that explains it.

Yes, the last sentence clarified it. Thanks alot mate.
need a quick help here. i accidentally left my charger at work overnight, and someone decided that its his/her's now ....ive searched around and cant find place to buy the original charger that came with the m8. HTC's website doesnt have it. amazon doesnt. even ebay dont carry it.
i need of a charger. currently using a LG G2 charger thats rated 1.8a 5v .....but with a super slow cable.
is the LG charger okay to use? will it damage my m8 in the long run?
i am also buying this cable on amazon. buy or dont buy?
http://www.amazon.com/Samsung-Universal-5-Feet-Charging-Smartphones/dp/B009OP8KCM/ref=sr_1_1?rps=1&ie=UTF8&qid=1401167720&sr=8-1&keywords=quick+charge+micro+usb+cable
yes, i know there is a quickcharge 2.0 coming out. seeing as the cable is only $5 ...im thinking it will do for now.
thanks in advance
HTC charger outputs 5V and 1.5A. As long as output voltage is same, you can use different chargers. Ampere value just affects charging time. Higher ampere means faster charge. In long term, it can shorten your battery's life, but I don't think 0.3A can cause an observable affect

I use all sorts of chargers. They are pretty much standard now as far as micro usb goes. As said some are higher rated some are lower. I don't think there is any that will damage the phone as long as its designed for charging and is 5v.
I too use multiple chargers and cables and the only issue I've had is a double length cable that works for charging but won't allow connections to the pc
XDA app on m8 running venom
I charger capable of delivering more current will not damage your phone since the phone won't draw more current than it wants.
