So i recently busted my default charger and started using one i bought, its not samsung brand, but lately i've been noticing that my battery dies quicker, does this seem look like normal battery life or is it possible that having a different type of charger is screwing with my battery? All i use my phone for is texting/phone calls. Thanks in advance
What are the power output on the charger? It seems that it drops really fast even during standby. The charger that came with the nexus is rated at 5v @ 1a.

Have you checked BetterBatteryStats? Looks like that phone is almost always awake, except during one period where the battery had less of a downslope. Also, it looks like even during the downslopes your phone is charging. Something doesn't seem right here, and I doubt it's your charger. It looks more like some application or other software is eating your battery for breakfast.
Yeah i also forgot to say, sometimes i'd look at my phone while in out and it would randomly say its charging. When its obviously not. The brand of the charger is called "On the go", no idea what kind of charge it delivers.

Are you on stock or have you tried flashing back to stock? If the problem continues even with a clean install of the stock software, it seems like the USB charging board might be messed up and may need replacing.

I've always wondered about this too. I seem to have a range of chargers that are micro USB that are 5v but < 1a. Is it safe to use these or not?

I'm Curious About This Too
I've been using the power block from my old Motorola OG Droid, with an output of 5.1V - 850mA, along with the usb cable that came with my old Palm Pre Plus (its nearly 52" long, almost 4 1/2ft!) andi have no idea what that's rated for. I seem to be doing fine as far as I can tell. It charges quickly on AC, nothing overheats.
But what are the consequences of using a power source with this kind of difference, if any? Consequences to using a power source with a greater difference?

Yes, the "a" (amperage) doesn't matter. It's just telling you how fast it can charge your phone, higher the amperage is, the faster it'll charge.
You can also determine how many watts the charger will consume by multiplying the Voltage by Amps. So if your charger was rated at 5v @ 1.5a, it will use about 7.5 watts. If it's less than 1a, like .6a, just put a decimal before the number.

Hello everybody,
Since the best phone ever died (or better: drown) on me (HTC Universal OFCOURSE!). I had to look for a replacement and TP2 seemed like the best of bad things. LOL!
I noticed that the wall charger had a 5V -1A(mpere) output. My (standard) car charger has a 5V - 0,5 A output. So I got the notice "your current power supply... not enough ...close some ...."
Besides the fact that e.g. tomtom uses more than the charger can give, i was wondering :
is it BAD for my battery charging at 0,5A instead of 1A ?
how much A does a laptop give when charging my TP2 trough USB port?
HAs this got sth to do with the fact that in some programs there is an option like "do not charge while connected to PC?"
I know this is more of an offtopic question, but I hope there is somebody with enough electrical knowledge to help me out! I posted it also in the general section, but since it is an TP2 issue maybe it is better placed here.
Sorry for possible inconvenience!
THX!
Kjoere
Each USB port churns out 5V at 500mA max (i.e., 0.5A).
Thank you mesquire,
Do you have any idea what the effect is of charging with different AMpere?
E.g. my BT-earphone has 180mA - so better not charge this through laptop I suppose (too much is never a good thing) - but the otherway charging with less A, that I haven' got a clue ...
C.
You can face problems that it starts to charge, but stops after x minutes.
I have replaced my carcharger with the original HTC CC C100 which delivers 1Amp.
Never had any charging problems with that one.
Hi ronh,
replacing is ofcourse an option, but I was mainly wondering what the possible effects could be on the battery. On a Dutch site I found that Lithium-Ion batteries have no memory effect so all ampères below should be "theoretically" be ok.

You can expect longer charge times through USB port than with the supplied charger.
A USB flash drive draws only about 100mA from the port, so the port should provide just enough power to charge your Bluetooth handsfree (but do make sure the device needs 5V to operate or you could fry it).
Hi mesquire,
thanx again, but I am still in the dark. You seem to make a difference between a USB port (500mA) and a USB flash drive (100mA), but i don't understand this (maybe my english isn't good enough ).
Do i understand you correctly is i say that the device connected also has sth to say in how much power comes out?
I thought the ampere is sth like a 'flow of current' and when more comes out than wanted by the receiver, it euh likes ... flood (too much current) the device (and does damage). Does this make any sense?
Ciao,
Kjoere
Your device will only pull the amount of amps required,
as long as the input voltage is the same you should be fine.
you will be OK to charge the phone at 500ma however this will take longer to charge,
I charge mine using my laptop regularly - that matches your car charger at 500ma,
you may find however, when using gps etc, that you are draining more power than being supplied by the charger and the battery will begin to discharge.
hope this makes sense,
Steve

they do have a memory, but the software/charger will not let you damage the battery.
anyway, assuming the battery can be charged at 1C (up to 2C is possible with some batteries, but can adversely affect battery life) you can theoretically charge the battery at a maximum of 1.5 amps safely. (assuming 1,500Mah battery)
TP2 doesn't have li-ion, it's a LiPo which doesn't have memory. They do have a limit on how many times they recharge as well as a shelf life, figure on buying a replacement every 1-2 years I'd guess.

are you sure ?? i went to the power settings and it says main battery: Li-ion
which i presume stands for lithium ion ?
Lithium Ion doesn't have memory.
Nickel Cadmium and Nickel MetalHydride have meory: i.e. if you charge it when it's at 70%, the next time it gets down to 70% it will think it's empty as it "remembers" that as the charging point.
With Lithium Ion you can charge them at any moment, ergo no charge. Adn they too have a life of about 500 charges.

The battery in my TP2 says LI-ION on the back, so perhaps some are LI-Po and some LI-ion? may go some way to explaining why some people are happy with their battery life and some not so.

Shouldn't really matter truth be told. As long as they have a rating of 1500mah they should last the same amount.

my australian TP2 says Li-ion in big letters, and Li-ion Polymer in the fine print
The difference is in cost, and weight, but the end result in a cell phone or pda is more or less the same due to the low power demands.
My TP2 battery says Li-ion on the actual label itself.

Hi Steve,
Thx man! So now i Know i only have to worry about voltage. So I can charge my earphone in my car (which only wants 180mA) and my phone (1A). You are right that it sometimes (navigation, BT) uses more power than it gets (500mA), I get some message saying that by the way.
Any way thanx a lot !

i would have said it's a small charger ...
It is a 1A charger, but Battery Widget Pro evaluates charge at 650 mA ( = 0.65 A ) for me.
Charging a 1800 mAh Li-Ion at 1.8 A will last one hour.
Charging a 1800 mAh Li-Ion at 0.6 A ( 1.8 / 3 ) will last 3 hours.
It is just as simple as this for Li-Ion and Li-Po batteries.
I can even say that your USB charge at approximately 300 mA even not knowing your specs ...
I think we can use a 2A charger without destroying the battery,
but i think HTC deliberately "lowered" the charge rate ...
Maybe someone here already tested a 2A charger and see a difference ?

Would you rather have it charged more quickly (like 1h or 1.5h) generating more heat and thus decreasing your battery life on phone which doesn't sport a removable battery?
I'm glad it's not that fast, the battery will last longer this way. If you don't care about that, get a "faster" charger and destroy your battery more quickly than the rest of use

Yes, i'm sure of that limitation too, but why does it charge in only 3 hours.
Looks like it is limited to 0.6A or my charger only charge at 0.6A
and doesn't have a good efficiency.
The two main possibilities are a bad battery which takes more time to charge
or a low charge rate from the charger.
While i suppose my battery is new and in good shape, it can be only due to charger or "software" limitation.
So for me the limitation is more like 600 mA and not 1A ...

Perhaps your not a heavy power user in a corporate environment who needs to charge the phone a decent amount in the airport, during the day, and so forth. HTC created a bigger problem by not allowing you to replace the battery.
Not hating, just saying, bro.

Learn about batteries before complaining about a phone you bought using a battery you don't understand. Lipo is not a Duracell and it needs to be used and charged properly.

Seems more like you have a defective charger, or at least not one rated at 1A. Try a different one?

Has nothing to do with how slow the HOX charges. The iPhone, blackberry, Macbooks, hell my old T61p ThinkPad all charge faster.
I upgraded to Jelly Bean the day before yesterday. But upgrading I've found that my charging time gone up quiet a bit. Its taking almost 30-40% more time to charge than it used to do earlier on ICS (stock). I'm running stock Jelly Bean on my Gnex. Is someone else also having this issue?
For me, approximatively 2-3 hours for full charging.
I think its more faster than ICS
I think I'll try different chargers to check the issue..

Hm... I'm no expert at this, but maybe JB slowed down the charging amount so GNex doesn't get hot when charging. I found my GNex to charge a bit longer after the update too. But now when I'm using my GNex, it doesn't get as hot as 4.0.x
Takes a couple hours. But completely dependent on the charger and cable. Long cables have more line-loss, and chargers vary from 500mA to 2.1A in output.

LOL... that's a good one. Also, the Galaxy Nexus charger is rated at 1 amp. You should not use a charger OVER 1 amp or you will damage the phone's charging circuit.
And I used to thought the higher Amperage doesn't affect the battery at all. Even if the 'amp' is high,the device will pull only that much of 'amp' that it needs. Rather we should ensure that voltage should not be higher than the rated one for the device.

A longer and/or thinner cable does have more resistance and so loses a bit of its power (V*A) over the run as waste heat. If it is already at capacity, that loss would slow charging a little bit compared to a shorter cable. If not, then its just wasted energy for heating the cable.
To your second point, any 5volt charger capable of delivering over 1 amp at 5V ( clean DC ) will safely charge a GNexus. Any unnecessary amperage capacity will just not be used. Charger will run cooler.
You could use a 6V auto battery charger with LOTS of amp capacity if it were 5V instead of 6V, and if it were clean DC, but it is not.
I got a Samsung micro USB charger and there is blurry text.
Anyone know if the charger is fake of it is Manufacturing defect?

ummmm not likely the phone has control over its charging... ever notice how it takes a second for your phone to start charging after you plug it in. thats because the phone actually makes the effort to connect the power input to your battery as well as disconecting the charger from the battery.. also having a higher output charger wont make you phone light on fire as the charger may have the ability to supply said amount of power but the phone will only "draw" a maximum amount as most are actually designed to do these days.... meaning i can throw a phone that came with a 700 mAh/ .7 Ah charger on a 2100 mAh/ 2.1 Ah charger and actually not have it draw more then lets say 1.5 Ah because that is the maximum it was desinged to do so. also leaving your phone on the charger after its full wont hurt the battery ... unless we are talking about several days straight. after a battery is full most charging systems enter what is known as a trickle or float speed. basically just enough to suplly power to phone as if the battery werent in it. say going from 700 mAh down to 200 - 400 depending on if your phone is actually deeep sleeping or slightly to heavily active. mid you if your screen is on during that time that number may still be higher.
now im not saying that this is always the case some really cheap and poorly built pos may cause a fire (saying as both phone and chargers alike) ... cause they do. but the reasons why they go up is nearly always due to poor quality and something fails instead of i plugged a high power charger into my phone and dantes inferno then visited on my bedside table.
I wasn't sure whether to post this on the Q&A or in Accessories considering its a topic regarding the charger. If it doesn't belong here then (Mods) please move it.
Anyways, it says on the charger that it outputs 1200mAh to the phone and yet in the CurrentWidget it reads the current output in the range of 30~280mAh but not more than that, this is also backed up by the fact that its taking very long to charge the phone, upto 5hours to complete a charge to 100%. This was not an issue before as it normally use to take apprx 2hours to charge. I've tested a Samsung Galaxy S3 charger, using the Nexus stock cable, which in comparison outputted around 800~1000mAh which seems close to its specs. Any idea if its time to replace the charger or is this normal for you? I've only had the phone for about 2months now.

I used it briefly while charging with only Battery Monitor Widget open to monitor the situation. Then I put it to sleep and let it charge. The current was consistently within the low range. I've checked battery health, capacity and voltage and its in good working capacity.
Either way there's not much I can do with a charger other than to replace it. Any suggestions?
