Hey! Guys I am having problems with the USB Charging, it seems to drain the 100% charged battery quicker (while using the phone, unplugged NOT charging) like one day and I have to charge the phone again, But when i charge my phone (100% charge) using the wall charger my phone lasts two and a half days. My wife also said she experiences the same thing with USB charged HTC Trinity Phone. I have tried on different computers and laptops as well but still the same and i know that USB charging will take longer to charge (500mah) so i leave the phone over night like 9 hours but the phone drains like juice. What kind of a Phenomenon is this.. Guys i need your humble thoughts and solutions on this because this is becoming a big problem for me since i use USB charging mostly... Plus I am not a very hardcore app, wifi or games user on the phone either... Darn...
same problem
I don't know why but i meting with the same problem. No idea why this happening it should be same from electric perspective.
When the phone cahrges via computer USB, the phone charges at a rate of around 90mA due to the phone running. Try with the phone off
Tried that as well, but it seems to be the quite the same but little difference since it last a little longer but still drained out in one freakin day. I am pulling my hair off because of this problem.. darn why is this just so... i mean like in the second post the process should be electronically identical right. only difference is it takes more time to charge from USB.... Grrrrr!
my phone hardly last one day..How do you make it last for 2 1/2 days?

Battery indicators do lie.
it all depends upon if your board can deliver enough current to run the phone and charge it. on my rig i see no difference between wall charger and laptop or desktop charging
the laptop is a studio 15 with an i5 and h55 chipset and the desktop is a core 2d machine with a p45 series chipset.
you can tell the phone to disable usb charging if the phone is on while connected to usb to see if that helps (it will still charge via USB if the phone is off)

any usb not from china will give about 500mah, whether it be my i7 laptop or z550 vaio, so specific components shouldn't matter.
usb charges a little slower, but no reason it should not last as long once its got all the amps it can take. weird situation man...my huge list of htc phones never had an issue, and i do use a work computer to charge via usb sometimes
Thanks for your thoughts guys!!!
Weird... Yeah thats the thing i am also using a Core i7 930 CPU and my motherboard is ASUS ROG Rampage III Gene board, so i don't think my system is the problem here...
The wall charger delives 2 amperes to our HTC phones while usb ports delivery only 500mA (0,5 amperes). It's not only a matter of charging slower but you can't deliver the full charge the battery needs to revert the chemical process of discharging when tou use usb port. With 2amperes the charging process reachs it's maximum.

some cheap mainboards cannot supply even 500ma. a good qaulity board can supply more.
want to test it? put your HD2 in the first USB port and then put a high power device like a wireless dongle or external USB HDD in the second and see what happens. if your board cannot power both, you'll drop your wireless/hdd connection when you plug your phone in.

Sir I have said that I am not a very heavy phone using guy, I am an average phone user. Plus I dont use the 3g or data connection here in my country since the connections are snail slow and prices are over the head and there is no unlimited data package here yet. I use the Wifi sometimes to update my twitter, Rss hub, facebook, weather tabs and very little market place... So my phone lasts for two and a half days when i use the wall charger.
Oh yeah and Guys, i tried recalibrating the battery by using it till the phone died completely and recharging it with USB (phone turned off) for like a day but still it drains faster than the wall charger rate.... I dont understand really...

This is why. The awnser was given, but people ignored it. To fully charge a battery it needs more amperes. Use the wall charger. The battery indicator lies, and is unable to acuratly measure a fully charged battery. It'll display 100% when it's roughly 70%.
Our batteries use Lithium ions as means of electricity. They use a Lithium compound, and move the ions from the negative to the positive pole. When there are no more ions to move, our batteries are discharged. When we connect to an external power source, the higher voltage will draw the ions back to the "negative pole".
USB supplies 500 mA (that's 0.5A) @ 5V (per specification, some motherboards won't be able to go that high, depending number of USB devices connected, etc)
European electrical sockets supply up to 2.5A @ 230V and although your HTC charger should only output 1A @ 5V, the topping off will occur much quicker.
Basically the more you have to charge, the more time it takes, and the bigger the effort on the current to pull the remaining ions back to the negative pole.
I am finding that in Android, my phone will not charge with either wall or usb charging. The phone shows that it is charging but does not actually charge. This is really unacceptable. It works in Windows Mobile but is not a listed problem of the Android builds. Are all of you using WM6.5 or Android? Or both?

I can Charge my HD2 well on both OS's but still when compared to android and WinMo when i use the USB Android does discharge heavily than WinMO and Android does the same when compared to WinMO on wall charger use as well... So nothing much more to say at that...
Charging mobiles using USB takes alot longer than using power outlet and this is valid for all kind of mobiles, ALSO when you charge by USB your mobiles battery drains much faster than charging from power outlet. (Electrical Engineers say so).
NOW why you don't use power outlet to charge your HD2 rather than using USB?
There are safety measures in charging from USB like, static issues from wall charger in some countries and then there is the ease of use from charging from PC while you are at work or away on a business trip..

I have been pondering...
Our phone is awesome in every aspect.... battery life is between 6 hrs ~ 7 hrs depending usage...
However... charging the battery seems to take FOREVER !!!!!!!!
it takes like 5+ hours to charge completely
if you want to charge it faster, wireless, phone, screen, etc needs to be off.
so that's the only inconvenient thing i found about our phone.
good thing is i can plug it in anywhere it has USB ports, including my car.
Make sure you use the correct charger. Many chargers that use the same socket do not charge at the same rate as the correct one due to internal wiring - I am not electrician but found this out the hard way.
Many USB/car chargers do not provide sufficient charge to even keep up with Athena power use.

The SIZE matters... also in charging.
May be I am wrong, other in this forum are better than me in physic
but
1) The power usage when connected via activesync, having screen backlight 50%, Big HTC HOME is around 200/300 mA/h.
2) The battery is 2200 mA,
3)if you charge it with a 500 mA/h charger... 500-250=250 mA/h.... 9 ours to have a full 2200 mA charge,
Athena have also XSCALE CPU (clock increasing during heavvy usage) and the power usage could increase very quickly (I have seen some 1000 mA/h peak) due to heavvy memory and CPU usage, or microdrive access
Looking at DIVX movies, full screen, USB 1.0 connected... the power DECREASES (slowly)!
And I would like to add, that after several tests with different chargers, no doubt that using HTC chargers makes a big difference, specially the car charger.
In the case of car charger, using a normal one ( output 5V 500mA ) I made a trip of 300Km and the power level went down from 100% to 70% using TomTom.
And with the HTC charger ( 5V 2A ) leaving home with 50% and arriving the same destination with 100%, again using TomTom.
I'm assuming that using other GPS software the results will be equal.
I used car chargers with 500mA, 800mA and also 1A and I tought that the results should be different but in fact it seems to me that one thing is what the charger "says" and another thing is what can "give".
hope this helps.

Yes, as I said it is a hard-wire issue
Yup, 2 pins need to be connected together before the Athena will go into "fast charge mode". You could hook up a 1000 amp bench power supply but still discharge your battery with GPS active - until you short the 2 pins. Don't remember which ones, its been discussed before on this board.
very insteresting...
yes i'm using the USB 500ma charger, just because past experiences has kind of though me that charging electronics with too much AMP it can burn it.
but it seems like the ATHENA can take that, since you have been using it.
I guess i'll shop around for a more powerful charger.

Not true. Electronics is in many ways like the water system, with the water pressure equal to volts, and the gallons per minute equal to amps. However, there's one key difference - electronics will only use as much as its needs (and no more). Not like trying to get a drink from a high-pressure fire hose where you'll hurt yourself trying.
A 60 watt light bulb will only draw 60 watts and will not blow up even though it could draw many thousands of watts before the circuit breaker blew.

hey everyone , i am having a problem my first recharge session for the xperia when the batter was fully drained was about 9 hours? is this normal ? for the first couple of times , i am recharging my phone through the usb cable from my computer directly ?
Please Advise
I've never charged mine through my computer, only synced. I will say it took very long to charge at first. I'd recommend using the wall charger and charging every night instead of letting it drain all the way.
Wall charger is the best choice, unless u have got a battery charger & patience to take off & put on the battery cover every time.
I doubt whether it is necessary to charge x1 every night?
I also find that using a wall charger gives a much quicker charge time and to my eyes a longer lasting charge... I only charge when it gets down to 20-40% so it could last as long as 4 days... (usually 2)
wallcharger takes about 2 hours till its full.
USB however takes far longer. not sure why but i guess the ma/h used for USB is probably far lower then a wallcharger
Yes, USB charging is slower than normal charging as the USB port can provide max 500 mAh, my old K800i on usb charging can arrive max 92% even after 6 hours connected, while on wall charging it is full in less than 2 hours.
And regarding this question, i have another question:
Will usb charging work with any usb wall charger? i leave the wall charger at home, and at work i use USB charging, but a co-worker has a motorola phone with a wall USB charging charger, can i use it safely on my Xperia?

Yes, if you check that Motorola output parameters are the same of our SE wall charger.
Thanks
Guys i did charge it from the wall charger and it took less then an hour to charge the remaining 50% which is great guessing so its going to take around 2 hours to full charge it from zero , , thanks for the help
I've got a split cable (two usb ports into one) that came with a portable USB HDD. It works faster when charging off USB.
also if you want faster charge time then make sure the X1 is switched off completely.
recharging ... Saving the battery
what i understand the the slower you charge the battery the longer the battery life ;it could stay with you for more then a year with good battery life
on the other hand quick charging the battery will decrease the overall age of battery you are going to change it with in a year or two
i am not sure of this info for cellphone batteries but 100% sure regarding the laptop lithium batteries
please correct me if i am wrong

As far as I know, the asnwer is yes for the first part. The slower the charging time, the longer the battery will last (theorically).
But, the time horizon is not 1-2 years. It is actually longer than that, 2-3 years for cellphones and 4-5 for laptop (own an HP from June 2005, still getting 3h of battery life out of it!).
There are lots of conditions that affect the life of a battery, check out at http://www.batteryuniversity.com/ for more info (that's a real useful site, up to me!)

Hmmm... great idea man... but I am wondering if it could affect the battery. Which is the total mah supplied?! is it less than the wall charger one? that info could definitively chamge my mind about the split cable
1) USB charge is way slower
2) Wall is about 2 -3 hrs
3) GSM plus average usage, 1.5 days of use
4) 3G plus average usage 1 days
what my laptop battery care program does to prolong live is that it maintains a max 80% charge. perhaps this is same for all battery?

Sincerely, it doesn't matter for me. 4 year is way too long and I never had a phone for that period, so I really do not care about it. The only thing I pay attention is to always fully charge and discharge the battery, every time.
Consider that the first bound to a battery life is its recharge cycles. Probably 90% of batteries dies/loose power because of too many charge/discharge cycles, the 10% left for other reasons (fast charge, totally drained power, heat, etc.)

the website doesn't say much about Lithium-Polymer batteries as opposed to Lithium-Ion which is all over the site. Li-Poly is what Xperia is using. I think you shouldn't overheat the battery when charging because heat will drasticaly degrade the battery life.
Yeh
Yeh, as a note to some former replied.
Li-Po (Lithium Polymer) batteries need to be kept in check, overheating can make them dangerous and explosive as well as reducing their life cycle.
Which point you charge the battery from with Li-Po does not mattery as long as the correct "conditioning" cycles are completed when new.
Also, as a note, I have once or twice attempted to charge my Xperia from the USB port on my laptop(plugged in) over night, only to find the battery of the Xperia was totally dead the next morning.
The USB ports of my laptop provide 500mA (standard) and the charger for the Xperia is 700mA so not a significant difference, but I guess other things affect the the USB ports on laptop (including Windows 7 having the ability to disable US ports to "save power").
It most probably assume the "device" connected is wasting power and so disables it. Although we want it to charge. Same goes for Windows Vista. This option can be disabled though.

Yes, but wall charging while using connected wifi does heat the battery relatively quickly (my Polaris, Li ion, gets vaguely warm, not as obviously heated as the X1 battery)
I've tested this with a new replacement battery - careful overnight charging when new - and similar behaviour still results
This has convinced me that the X1 has a serious weakness, as charging while wifi connected is a long-standing work habit. If the wifi is connected without charging, a usable time of 2-3 hours is all you get (no good )
Is it alright to have the SGT plugged into a USB port all day (approx 9hrs) ? I'd like to have it keep its charge (maybe even gain a little) while I'm at work so I can have a decent amount of juice for the trip home and until i go to bed. Or is this a good way of burning out my battery real quick? Thoughts?
Oh and as a side note on USB charging, I was able to get from 15% to 99% in 7hrs with the screen off the whole time.
Is it a slow-charging USB port? Or is it a powered hub? If I'm not mistaken, slow-charging a lithium-ion based battery pack is actually better for its life as opposed to rapid charging.
Its the regular port on the PC not even high speed usb so i guess it isn't powered.hmm guess the charging part is OK..but what about leaving it plugged all day even if the battery is at 100%?

All usb ports are powered by definition. They can supply up to 500ma (half an amp). Dont worry about leaving your tab plugged in, devices are smart enough these days not to overcharge the battery.

Coda is right, technically they all have power . If not, how would any device charge? I guess I really meant to say USB ports charge at a higher MA or something for rapid charging (wall-socket USB adapters?).
Also, Coda is right again. Devices these days are fairly smart. I typically leave my HD2 plugged in all the time with no problems.
itll be just fine plugged in!
ive been part-charging mine at random intervals (sometimes for 20 mins at a time a few times a day) and leaving it charging over a day from both powered hub and charger over about five months... though i have had two or three near total discharges
the battery has got better, which is what you would expect from the tech - sammy even provides a nice notification telling you the device is fully chraged
i wonder if they put that in there to account for unexpected battery problems down the line? in any case, ive read that low-powered charging, even unregistered by the battery, will increase the lifetime of the battery and also charge at approximately the same rate... ive seen this with my phones charging over pc usb
Great! Nothing to worry about then. The tab would look really cool on my office desk sporting the same screensaver as my PC ..'the Matrix' scrolling code.
I think it is OK. I bought a 2d adapter, one for the office. Since Sammy is selling docks, it also means that it can be powered all times. On the other hand I remember my Archos which I used to leave it on its dock all times... battery was killed in a short time. When you sell multimedia charging docks it means that you can leave it there, no? Not in the case of Archos.
If I have the screen on while plugged in, my battery % continues to drop and the device itself feels kind of hot. Could I have a problem or is this normal?
My battery life has also not been so great.

Mine doesn't it keeps going up, though I haven't tried playing games. It does depend on what you are doing with the device, if you are running applications that max out the processor it will possibly drop.
The GSII would drain while plugged in if the screen was on. You would see a noticeable drain while using GPS and Music and driving. The only way to make it work was to turn the screen off on the device, the GSIII has a better charging chip in it, and it isn't limited to 650maH (from what I can tell since it is charging when using GPS)
I noticed it while using a usb car cigarette adapter as well as a usb port on my laptop. the car adapter is a 2 amp charger capable of charging a tablet. I will see how it performs with the oem wall charger.

I'm curious about this myself....I'm leaning towards not leaving mine plugged all night. I 2 have done this in the past with other phones and can't be certain but maybe this is a rEason I had horrible batt life despite efforts to Better it. So I'm gonna stick with charging/topping off when I can. Gonna start just charging when I wake up while I'm getting ready for work. I did notice that when battery is completely charged a message comes up telling u so and to unplug. So I'm gonna follow directions haha.
Sent from my SAMSUNG-SGH-I747 using XDA
All modern smartphones have chips that control power, and cycle charging appropriately to not abuse the battery. Many phones monitor the temp of the battery and such to ensure a good and safe charge. You can leave it plugged in overnight just fine..
It definitely doesn't like 3rd party adapters. I'm hoping it will at least accept the tab adapter with samsung's cable so that I can charge it at work without buying a dozen chargers, but...
(One charger I used is understandable - turns out its only 300ma. Whoops! But using full 1A chargers wasn't helping either, it went up maybe 1% every 15 mins. The stock charger ran it up fast enough that it was charged from 70% in under an hour.)
I use SetCPU and have a setting to reduce the clock when it exceeds a temperate parameter. You could also set a max clock for when it is plugged into a USB (Computer/Car charger). That could help it stay cooler and charge faster while not plugged into the wall.
I charged from empty to full this morning when plugged into the wall in about 3 hours. I haven't tested on my computer yet.
I went through this when I first got my Evo 4G. I did not realize at the time that the 500mA charger I was using with my Blackberry Storm (horrible device) would not charge my Evo while doing anything power intensive (like using GPS) and I quickly drained it on a car trip.
I went on Amazon and bought a $20 Schosche iPad charger that claimed to provide 2.1A which should be plenty. On that charger the phone would charge while using GPS but very, very slowly.
After some more research I found that some chargers caused the phone to switch into "USB" charging mode and others would switch it to "AC" mode which would draw much more power and charge faster.
This is the charger I ended up with and it works great:
http://www.monoprice.com/products/p...=10826&cs_id=1082602&p_id=6766&seq=1&format=2
My Evo charges just as fast as it does on the OEM wall charger. I don't have my SIII yet (thanks Verizon for being the LAST in the US to ship them out...) so I can't yet say if this holds true for the SIII but I assume it will. At $1.22 it's not much of a gamble.
Hey all
I'm having this really strange issue, trying to figure out if the phone is at fault and whether I should RMA it.
When I try to charge it through my Macbook pro, it gets to around 16% and stops charging. When I charge it through my car's USB to 9V converter it manages to charge properly but loses that charge very quickly.
When my phone is connected to a power outlet (via a samsung convertor that came with my Nexus S), it charges well and holds the charge for a while.
Should I RMA?
The voltage doesn't make any difference. (Well it does, but it simply won't charge if the voltage is too low) It's the current you should be worried about. May be your Macbook pro and your car USB simply isn't giving out enough current to charge the phone? Laptop usb ports tend to have very low power rating.

The voltage doesn't make any difference. (Well it does, but it simply won't charge if the voltage is too low) It's the current you should be worried about. May be your Macbook pro and your car USB simply isn't giving out enough current to charge the phone? Laptop usb ports tend to have very low power rating.

My computer has no issues charging any other device...
And to the gentleman that recommended not to charge it in a car.. well that'd make my phone far less useful. I need to be able to charge it in my car.
