USB to PC - Disable charging? - Desire Q&A, Help & Troubleshooting

Is it possible to make the phone not charge when you plug it into the computer? I just want it to charge while it's in the charger.

Hmm... i don't think so. AFAIK, any of the sync options you choose while connected via USB will still result in the phone charging.

Just out of interest, but why? Li-Ion batteries don't have a memory effect, so there's no problem with a little top-up charge here and there.

Just something I came up with, I always thought it hurt the battery by loading it like that even tho it's a Li-Ion, and I still believe it does.

don't charge it via A/C adapter if you want better battery life.
and how many times have you cycled the battery?

Just don't charge it at all. It's so stupid to charge your phone, nothing good comes from it! And if you need to charge, NEVER, use the A/C Adapter that came with your device like paOol said!
/Sarcasm off
Your USB cable isn't braided with 24-strand Unicorn hair. Therefore the power coming from the charger isn't pure enough for our Galaxy Nexus.

Stupid as it sounds, there is some truth to it (though OP probably didn't know, lol). Quick chargers wear out the battery a bit faster than a slow charger, so charging from the usb port on your computer is slightly better for the battery, but the charge takes a lot longer. This does not affect your battery capacity per charge, but affects how many cycles the battery lasts before it wears out.

This guy knows!
Lithium ion batteries actually like a slow charge and discharge rate . By that I mean to prolong the cells life and IRS storage capacity. Optimum rates vary a little but I found in testing that makita lithium batteries provided best service with .5C charge and discharge rates...
Not exactly the same as your phone battery, but the same chemical make-up inside the cells..
Anyway.. lol

hahahahah yes.
I heard that if you use a potato to charge your phone it doubles the battery capacity.
that seems about right to me. I browse a lot and routinely get about 3.5 hours screen time before my phone goes to the red zone. Which IIRC is around 15%?
I have my browser open and the brightness to 40% and my bluetooth off.
The battery life has been the sole black spot in owning this phone so far. I am sure the owners of the next generation phones will make all of us jealous. I bought a spare -regular- battery for just this reason.
if you want your phone to be ugly as **** and look like you have a tumor on your leg you can get this

[Q] Does it harm the battery if i do this?

I always had this question in my head and i think its time to ask. All android phones i had does this and i wanna know if this does harm in somehow the battery.
When i plug the phone to the PC to transfer some files it recharges the battery too, sometimes depending how big are they, the phone stays connected for longer. I want to know if it harms the battery doing this small, medium charges while transfering files.
Doesn't harm the new batteries.

... what Flo95 said.
More specifically, lithium-ion batteries don't develop the 'charge memory' older battery technologies like NiCad do if not allowed to fully run down before a charge.

Older batteries suffered from "memory effect", meaning that if you charged them before they were empty and until they were any less than full, soon enough their capacity would deteriorate.
New batteries don't have that problem. You can charge them any time you want for as long as you want. In fact, it's advisable to not let them discharge completely and charge them often.

Thanks for explaining it for me
It seems a bit ironic, previously we had to be aware from charging at any time and it was stronly recommended to charge only when battery is completely dead.
While these days it's better if we not let the battery completely discharged

This phone takes FOREVER to charge.

Seriously who thought it would be OK to sell a phone that takes nearly 6 hours to charge on USB and nearly 3 on the wall?
Its not even like it gets to 80% after an hour then trickles.
Rant over.

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 ...
Heard it all now... battery charge though put it on charge while you sleep (PROBLEM SOLVED)

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?
Even with a 2A charger I have, phone does take a dreadfully long time to charge. My Galaxy Nexus with the extended battery charges to full in about 1/3 the time.

Has nothing to do with how slow the HOX charges. The iPhone, blackberry, Macbooks, hell my old T61p ThinkPad all charge faster.

there are no problems whatsoever with doing this.
Depends on your definition of continuously.
You need to let the battery drain at least a little once in awhile.
I had a laptop that I left plugged in with the (li-ion) battery for a long time and now the battery is useless.
yep, if you NEVER unplug it - the battery will be completely useless
if you are thinking of keeping it continuously plugged in, what i do with laptops is just to remove the battery and use it without

Works on mine.
1. Keep battery in note
2. Plug charger
3. Turn Note On (if it isn't already)
4. Remove battery
Note should stay awake
^Wow.. Really? I'll do that at work! No more killing my batt! Thanks

Yes you can I do it every night. Sometimes I plugging in with 80% charge. I charge every night whether the phone needs it or not since I've had the Captivate I've had no issues. Sometimes I leave the phone on charge when I'm watching TV and it's next to me on the table. There is circuitry in chargers and in the phone to stop the charge when the phone is full It becomes a trickle charger after that
I leave my phone in one of a number of charging cradles when I'm home

I went camping, and the only other batteries I had were smaller. The old batteries from my Vibrant (1500mAh) fit the Note, more or less. I just wedged a cut piece of packing foam in the gap at the bottom to make sure it stayed put (I contemplated taping it there).
Using an alternate, smaller, cheaper 3.7v would save you from blowing out your OEM battery (particularly if you have an old one that already won't hold a charge).
The manual says not to keep it plugged in for more than a week. I keep it plugged in for about 20 hours a day and have had no problems in six months or so.

[Q] Can different chargers mess with your battery?

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'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.
