Had my Ameo connected to may Laptop via USB for several hours without much usage.
However, when checking battery status the battery went even worse. I had only 20% remaining battery power.
Update: Battery power went to 10% now while connected to Laptop...seems to me that USB power is insufficient to charge the Ameo. That means it is impossible to work for a longer period with connected Ameo because the battery runs out of power !!!!!!
Who has made any other experience ?

I see the same issue, although not as severe as for you. When I'm connected through the USB cable I don't gain nor lose battery power. I have had it connected for mopre than 12 hours in a row and see no change in battery power.
Not sure how you could resolve this.
Must be the case. Mine does charge (USB 2.0 - how 'bout yours?), but, it can take 12-15 hours or more to charge from 30% to 90%. Never seems to get to 100%
Yes me too. it's such a dramatic different when comparing it with Universal. Much faster charging.
I think this is mentioned in some other posts, wonder if there was a way to sort this out?
It appears the Athena uses more power than the USB can replenish. Strange. Ive had a universal and alot of other HTC devices and they were fine like you said.
mmm! strange
May be by using a powered USB Hub would make it charged. I'm going to try it tonight and will post the outcome soon.

I was thinking that would be the solution but I don't have a hub.
If it works with yours I might need to buy one.
rating
The supplied adapter is 1A, USB nominal is, i think 500mA so half the adapter current. On the two pc's I've tried mine on they sustain but not really charge the athena or if they do its a very slow charge.
With backlight up and wireless on I don't think they even keep pace.
From wikipedia:
"The USB specification provides a 5 V (volts) supply on a single wire from which connected USB devices may draw power. The specification provides for no more than 5.25 V and no less than 4.35 V between the +ve and -ve bus power lines. Initially, a device is only allowed to draw 100 mA. It may request more current from the upstream device in units of 100 mA up to a maximum of 500 mA."
After charging using powered USB Hub I can confirm that my device does get charged. The result is better than just using standard USB port, but worse than using the supplied adaptor.
The power consumption is because of the MD and the screen (which is much larger than on the Uni, hence the slower charging with the same amount of power).
You can't turn the MD off. However (if you don't have a powered hub), you can turn the brightness of the screen down whilst on external power and, hey presto, it will charge faster.

Yes, this sounds like a problem we had before with the universal. Turning off wifi and backlight after a few minutes of inactivity; turning brightness down to very low (next to lowest level) on external power, improves it. In fact, my ameo is now fully charged on usb. Not very fast though.
I did get a scenario using TTN 6 when it did go off in the car. The battery charger didn't seem to be doing much good. So for long distance navigation, I'd recommend fully charging your device before you leave.
I have a Veripart Car Charger mini usb that I use in my car when I use TomTom. I have the brightness at maximum, UMTS on, Push-mail on and I make phone calls. And still is has more power when I reach my destination.

May be you should use a better powered USB Hub (1 A perhaps).
Using a 6V 2100mA...
However, this may be depending on the usage of W-Lan. Seems to me that W-Lan needs a lot of power when switched on.
Wit W-Lan "On" there is nearly no charging at all.

How about charging while turning off the W-Lan? No charging at all too? Mine get charged. Only it's not as good as compared to using supplied power adaptor.

MD is MicroDrive.
But I think the Microdrive should sleep itself when unused though. I would be surprised if MD in Athena is continuously spinning.

I've had an o2 mini s for about a week now and i'm pleased with it on the whole. My only real concern is battery life. My mini seems to drain much quicker than by xda 2 s which I had before. I seem to drop about 10% in 1 hour 10 mins and that's just a few calls/txts and minimum fiddling.
8:20 100%
9:42 88%
I've dropped all the o2 software and don't have any tricky 3rd party apps installed only;

I've read quite a few posts about battery life being good on this phone but i'm not seeing it. I'm still in my 14 day cooling off period and i'm considering sending it back for a replacement.

Is Wifi off, bluetooth off. Do you check your email every ... minutes over GPRS?...
With email checking every 10 minutes my qtek battery last at least 2 whole days.
wifi/gprs/bluetooth all off - not used today
Just phone today - maybe 12 calls.
Time now 14:21 battery at 61% !
Now i'm worried ......I reckon i'll be down to 30% by this evening.
16:32 - 49%
maybe there are problems with these batteries i had problems with charging the battery it didnt seem to show correct level, sent it back for another unit
17:26 - 38%.
If another goes we'll be up here all day.
My battery life seems to be utter rubbish every time I charge my MDA Vario over the USB link. I can go to bed with 100% battery and find it dead by morning. This has happened two or three times since I bought it on 5th November. Last Saturday morning I had the USB cable connected to download some music to my SD card with 100% charge at 10:00. I played music for about an hour through the supplied headphones and by 13:00 I was down to 50% battery. By that evening I was down to a few %. I've read reviews that you you should squeeze about 10 hours of continuous music from this thing on one full charge so an hour of music and 7 hours of standby/sleep seems pathetic.
If I charge using the mains charger and sync over Bluetooth I get a standby battery life of about 5 days. Obviously that is shortened with use so in practice I am charging it every 2-3 days (no point starting a day with only 20% left!).
I have no idea why USB charging is completely hopeless. I have tried soft resetting or closing all active apps after charging, to make sure ActiveSync isn't actively running and causing a drain (just as you are advised to with a Bluetooth sync) but that seems to make no difference. USB charging is rubbish. Mains charging is the only way to go, IME.

I confirm USB charging IS rubbish. The reason seems to be that the power available out of that conector on a PC is not enough to charge properly... I had the same issue with BA and Himalaya...
Answer: get a USB charger / car charger that can deliver 1A minimum.
BTW I found a craddle for the Wizard in Dubai @ Plugins. It comes with USB port/cable + power adapter. Works like a charme.

My C500 Did that when I had it Plugged in the Front USB ports on my case, I normaly had it plugged in to the onboard USB at the back of my pc with a usb ext cable so I could have it on my desk but I went off to a lan party and when I plugged everything back in I put my USB cable to front usb port and found it was Discharging my Battery instead of charging it, got my usb in Back port all is fine again now
Maybe you have yours in to the front USB port or non onboard port?
I use a laptop, which only has two USB 1.1 ports but they each supply enough juice to power a USB ADSL modem (not that I'm using one of those these days), which is more than some PCs will manage and also my USB hard drive, which my Shuttle won't. So there is no lack of power from the USB ports on the laptop.
Of course, the USB spec only permits a maximum current demand of 500mA so any equpiment expecting more should not be using USB for its power supply. In any event, the phone does charge from the USB ports, albeit very slowly, but eventually the orange charge light does go green. So my situation is not one of discharging instead of charging.
I've just swapped my ROM from Vario to k-jam so I'll see if that makes any difference to the performance. I know it's given me 802.11g, which was missing before.
I had an M500 briefly (Magician) on Orange that had very poor battery life, it was one of the reasons I ebayed it, gave the contract sim to my wife and started a cheaper better value T-Mobile account with an MDA Compact, which
had better battery life. Typically overnight after a full charge the Orange unit went down to 75% and the T-Mobile one was at about 98% on standby.
My Vario I have now, my other T-Mobile account has very good battery life and charges very well off USB. If I sync it in the morning whilst reading my emails and stuff, let it charge USb for about 25 mins, it'll be full and by the night it will have dropped down to about 80%. This is with about 30 mins of calls, about seven or eight emails sent/received and maybe 15 mins with WIFI on.

I can't remember for sure where I got the k-jam ROM ( I think someone saved a copy somewhere) but try here - ftp://ftp.clubimate.com/ - and then save file K-JAM_WWE_1010903_106_10110_ship.exe
That is a self installing upgrade that includes the whole k-jam ROM and k-jam extended ROM files.
I don't know where to get a Vario ROM from. I did back up my own copy (I hope) but the method is a bit whacky and as I only have a 1GB mini-SD card my ROM backup image is 1GB because the only way to secure the image is to dump the whole card to a file.
Before you go playing around do make sure you have your own backup of the ROM or if not the whole thing then the Vario extended ROM files at least. I'm using the k-jam ROM with the Vario Extended ROM.

Hi,
Is there any way to disable USB charging? I didn't connect USB very often since it will charge automatically and I don't like the battery be charged very often. It might kill battery soon. I like to sync with bluetooth; however it is much slower than USB. It's amazing if there is any tool to disable USB charging. Because it will sync fast and will not hurt the battery. Thanks for the suggestions in advance.

You are thinking of older batteries such as Nicads. Topping up often does not hurt Lithium batteries, in fact it's better for them. Their main enemies are deep discharge and heat - and that's exactly what you're subjecting it to by letting it run flat, then charging for hours to get it back to max.

Dear Ineedtoys,
Thanks for the reply. I understand that there is no so called "memory effect" on Lithium battery; however when I checked the battery spec, I always found that there is a "charging cycle limitation". For example, a specific battery claimed that it can be rechaged 10,000 times, then very USB charging will be counted also. It will reach 10,000 times faster. This is my concern. I don't know if this is right or wrong. Can somebody help to clarify this?

That's true. It's the same with Notebooks. The more you charge it, while it's in use, the faster the battery gets "killed"!

Answer my own question.
I am quite sure that the USB charging can be disabled since I used to see the config on a HP device. I also believed that this can be done by 'registry' since it is Windows tradition. I finally found it after a short study. Please go to
HKLM\Drivers\BuiltIn\usbfndrv
and change the
EnableUsbCharging to '0'
then
soft reset => Bingo.
Hope it helps.

Hrm.. This is interesting.. I used to always charge my G1 with AC power. However past couple days, I was lazy and used my laptop USB to charge it. I noticed those days however the battery life was HORRIBLE! I mean I couldnt even get past lets say 9 hours without the battery being at 15-30% and this is without doing anything major. On AC I always got home with 50%.
Has anyone else noticed this? I am using the power profiler mode, so unless something goes out of whack on USB power mode, which I dont see why it would...
(Also I did turn off phone and back on to reset anything just in case) but its just a interesting thing that it seems USB charges suck?
Yes I noticed the same thing, used the computer USB to charge and only lasted about 6 hours of the day. I use the Wall charger and get about 9 hours consistantly. Not sure why but I have noticed this several times........
Mark
Every Tmobile rep I've talked to always say the AC charger does a better job of charging the phone.
Hrm, is this info on a G1 Wiki yet? Would be good info to pass around. My logicial guess is that USB charging can only allow the voltage on the battery to charge to "x" max. While AC power being stronger could bring the battery up more. I cant say thats fully the case.. but since the USB cannot supply the power max a AC could.. its possible.
I've got and idea for a little test, would be helpful to see a lot of different users results as well..
Get Battery Graph, run your phone dead, plug in usb charger and graph. then take a screenshot of the overall charge time, clear graph
Run it dead again, plug in AC charger #1 and and repeat
Repeat the process for each additional recharging apparatus
The reason I mention additional apparatuses is because I think my car's DC charger does better than both ac and usb (tho this will be hard to get a full accurate graph of) , also I use my gf's moto charger from time to time (i know bad mojo)..
This will probably take a few days as charging will take place at sleep time for me but this should give us an over all view of how things are working if we all get pretty consistent results..

I've had 4 different miniUSB charging phones and all of them have had this same behavior. I'm sure that the voltage coming through the USB isn't as strong as AC.

Im wondering, if I use my usb while plugged into my laptop (for tether wifi app) will this hamper my battery life? I have the extended battery (2200mah) and I get far better life from it and to be honest I like the bigger size because the g1 felt too much like a toy to me before.
What do you guys think will this mess it up? I dont have wifi at home so the tetherwifi app is the only way I have net on my laptop unless I go somewhere where they have wifi. Cursed neighrbors and there password protected networks!
Might using a USB stepup voltage converter help? I've used it to charge my Nokia phone on usb in the past so it would reach the battery is full message.
The argument is usually that laptop usb don't output adequate voltage.
Its cheap and works for me on the nokia phone, Haven't tried it on the G1 yet though, can anyone find the ac charger's output info?
http://www.dealextreme.com/details.dx/sku.2649
yea this goes for alot of devices.. my ipod/psp charge pretty slow compared to wall outlet, however i didnt really see strength difference.. never tried USB charging my g1
I think it's worth noting I have the G1, My girlfriend has a HTC Touch(Elfin)
Both use Mini-USB Charging, both have 5V 1A Batteries (can't remember mA rating though)
Through a wall charger, my phone seems to charge quicker, but I get no longer out of it, the same behaviour is exhibited with the Touch. Both USB and the Wall charger are rated at 5V (It would/coul destroy componants methinks if it was any higher).
USB's Specifications say that unless a device has special permissions, It can only draw 500mA, with a maximum of 1000mA and a very rare (as in, one maybe two things use it) 2000mA.
Also, I have a custom made USB charger, that takes 3 AAA batteries (1.5x3 = 4.5)
It causes the phones internal battery to mess up, but does actually charge it (just a lot longer than other methods). It's more of an extended battery however, as it says it is charging, yet the battery life slowly degrades.
It's simple really and it has already been explained.
The USB port on a computer is limited to 500mA for most devices where as AC chargers like
The G1's can rpovide up to 1 Amp, even more/less depending on the chargers.
It doesn't depend on the voltage but on the current delivered. Less current equals
More time to charge and viceversa,
There is no myth.
anyone knows?
possibly need to write a custom oem_misc.dll. if some one can, then we can have TV out too ...
i heard it is just a reg change
anyone knows pls?
Don't know the reg change in this case, but guess won't really work.
For instance, for enabling FM radio without headset, changing the headset state in reg won't work. I would be happy to be proven wrong though

Hi leobox1,
Not sure that there is a way to enable this. Charge rate is determined by battery voltage and available current from the charger, not by software (other than the simple battery management chip in the battery). So if your battery is low and you have high power USB connection, it will take as much charge transfer as the battery will accept, provided the supply voltage can keep up. I don't think that the charger circuit can recognise the difference between low power USB, high power USB, or charger USB connection.

I don't think so. When HD is on, the current consumed at a given battery level of charge for a given (same) voltage is higher with wall charger than computer USB. Don't have the values that I measured once... But this doesn't seem to be the case when HD is switched off.
So there has to be some kind of monitoring going on by the CPU.
The charger has the two data pins connected together so the handset knows it is receiving power from the charger and not a USB port. The device will then charge with as much power as the charger will allow, up to 1000mA
The amount of USB power definately changes the speed at which this recharges. I purchased a 3amp car charger and it will charge my Touch HD in half the time it charges from the wall charger. My laptop puts out a small USB power supply and it take all day to charge my phone. My old Pocket PC had the selection for fast or slow charge, this one seems to handle it on it's own.
hmm so in short it is beyond our control?

3 Amps? Are you sure, I don't know if I would want to connect my Touch HD to a 3A supply. Where did you buy it from?
Picked it up from ebay. It works really well, no overheating. The phone only takes what it needs, the charge is controlled by the phone not the charger.
Oh, I know the phone will only pull the power it wants, that is not the issue. A 3 amp power supply would cost quite a bit if it was a decent regulated one, and I would not use anything but a regulated power supply.
So I was guessing you were using a 3A unregulated supply. Which is something I would be very wary of, the risk of a voltage spike is going to be higher than with a lower amperage.
the only reason that the phone charges faster using the htc charger is so that people like us spend more money on official htc accessories.
its not just htc that do this.
why do you even think they have this extusb instead of a normal usb port?
a normal usb port on a pc is rated to give out 500mA (half an amp) of current.
that doesnt mean that a normal usb socket cant accept more than that though. just think back to the old htc devices that charged much faster.

We (noordwyk & Me) managed to put together a Portable Charger for the Diamond. I have attached some pics:
noordwyk will soon post the diagram
Sounds cool anychance of some more info: Like what you used and a diagram to show how it's wired? Please.
When i get time I shall upload a graph
For everyone without soldering skills - there are plenty of portable external chargers for sale, even one from HTC:
HTC Battery Bank BB G300
i've bought a couple of portable chargers. Neither of them worked. In bothe cases i plugged them in and my diamond showed itself as being connected to a power source on the task bar. The light ring pulsed in the charge pattern also. However after a few minutes of "charging" once removed the battery level is lower than when i plugged it in. This is the case whether i had the diamond on or off when charging. Chargers work fine using different adaptors on other none wm phones. The thought i had was that the chargers were outputting enough to power the charging circuit but not enough to charge. This in turn is draining the battery. any thoughts ppl??

Portable chargers and HTC don't go together. You MUST switch your phone off to charge it otherwise the PMS will get confused and keep changing power sources like External > Internal > External > Internal and so on. Just like a light switch when you turn it on it takes more power than just leaving it on for 10 minutes. Portable chargers have a charge rate of ~250 mA which is 1/4 of a Official HTC Charger.
Conclusion: If you want to use a portable charger ONLY use it after turning your phone off otherwise its USeLESS

Just like a light switch when you turn it on it takes more power than just leaving it on for 10 minutes. Portable chargers have a charge rate of ~250 mA which is 1/4 of a Official HTC Charger.
Conclusion: If you want to use a portable charger ONLY use it after turning your phone off otherwise its USeLESS

Is it the same for car chargers ? If so, how can we power the device for, say, using GPS navigation for long trips ?

Nope! Car Chargers work well. I use one regularly - specifically for the reason you mentioned- usage of GPS while on long trips.

Basically what i thought then. I must be getting particularly rubbish ones because they dont even work when the phone is off. I gave up on them a few months ago and just bought a spare battery and charger. Quite cheap off ebay and a battery is a smaller item to carry than a portable charger.

I would be quite interested to see a wiring diagram of this too, it'd be great to be able to just grab a 9v and charge up on the run...

Well its true in the UK
Shouldn't be too hard to build. Take one of these (high efficiency!), solder the 9V battery adapter and the mini-usb cable to it and your're done. Only thing I worry about is the capacity. You get NiMH 9V cells at approx 250 mAh. Given the battery voltage is 9V, you get a total energy of 8.1 kJ stored in it, which translates to 450 mAh at 5V (input voltage of device). Given that this back-of-the-envelope calculation does not take conversion losses in account, you can be happy if you get 20-30% charge out of it. Maybe you could wire several 9V batteries in parallel so you get more charge out of it. Which I am gonna try out right away .

No. MythBusters tried it out. Turning on an incandescent light bulb (60W I think?) uses about the same power as leaving it on for 17 seconds. Fluorescent light bulbs didn't use significantly more power to turn on.

Ok...
The only problem is that my Diamond seems to use more power than what is provided by the car charger... So the car charger limits the discharge, but that's all.
On my old prophet, I could have used GPS for days (using a bluetooth external GPS of course).
It's a pity the diamond is not as power efficient.

I agree with you. A fellow XDA member posted somewhere here that he started of with 100% for a 6 Hour journey using his diamond and when he got to his destination he said it was around 30% left!
It's not too hard to build one, as soon as I remember, it's adapter (for the battery), 5V regulator and a female USB (it's easier to find, you use your sync cable and you can charge other things, MP3 players, portable speakers etc.).
Am I right, or you have different design.
Also, you can use 4 1.5V batteries, I've got few 1900mAh of them, so they should last longer. Also, I think the regular 9V battery is bigger than 250mAh.
Well i soon will be updating my E42M website with this years invetions so visit it when you can

Hi,
I have a navigation software on my x10. everything works fine but it seems that this programm needs so much battery that the charger can´t charger the battery.
With navigation turned on and charging the battery is still getting lower and lower.
I have a self build car charger in my car with 1000mA but it seems, that it´s not enough.
Have you any suggestions, how to solve the problem? Is there an app to change the cpu usage for the navigation to e.g. 60% instead of 100%? Or is this only possible with rooted phones?
Thanks.
Same Problem over here.
My only solution --> 2G instead of 3G and turning off W-Lan.
In that way (with GPS and Bluetooth active), the phone at least charges very slowly and doesn't drain the battery.
I had turned WLAN, BT, 3G off. But my battery was still not loading... Maybe I have to switch from 100% Screen brightness to automatic. I will try it the next time...

But the charging symbol shows up?
Did you shorten the Data+ and Data- Lines on your selfmade car charger?
I guess, you build it, like i did:
I took a 12V cigarette lighter to USB adapter.
Then I broke that thing apart and soldered a (micro) USB cable directly do the USB jack.
To make it working, I had to shorten the inner two lines.
Otherwise, the phone didn't charge at all.
Then I glued / taped / bubblegummed the whole thing an threw it behind my radio
Or did you build an other solution?
I build it myself, not broken a charger, and yes, it´s working (data is shorten), but it´s not enough to load the battery during navigation. If I turn navigation off, my battery is charging as usual.

Nice one
Uhm.. what about rising mA a little further?
I've no clue what max. should be.
Probably you know?
I've also seen USB Chargers with 1500mA.
But I dunno, if its a good idea.
Phone + Battery would also heat up a little further...
Another Idea:
Maybe there is a couple of Apps running at full load in the background?
Take a look around in this forum.
Especially at the "helix launcher" and the "battery life issues" threads.
You can also download the App "SystemPanelLite".
With that one you can search and monitor the running Apps and their CPU consumption and so on.
With "Task Manger" (the one made by Rhythm Software) you can set up a auto kill rule.
Hope, that helps...
I have also tried to charge my phone with my car charger left from Omnia HD and the phone is not charging ??? HTC Desire is charging but X10 is not. Can someone tell me what could be the problem ??
Tnx
@damirbusic
The Problem is, that the two Data Pins (2 & 3 - the two middle ones)) must be shorten. Then the X10 is loading...
@McKebapp
I´m tried it with helix launcher and have some applications auto killed and all tasks closed. But it's still not enough.
It´s possible to charge the Li-Ion Batteries with 1500 mA. That will be my last solution. Don´t want to charge it with 1500mA due to overheating, specially in the summertime...
I don't have this issue at all, weird

@UserX10:
Uhm... that is strange after all...
Which Navi-SW do u use?
I use "Sygic" for onboard navigation.
Normaly I use Sygic, too.
I tried Navigon, too, but the same result.
Both Apps draining the battery more then the charger is loading...

Really Strange...
Which temperatures do you have to deal with?
My last Idea: Maybe some overheat protection, that limits the charging rate?
By my one is the problem defently the temparatur... when i hold me phone in to the airstream from the aircooling then does the phone charging works. If i let the phone just on the right side of me on seat the it doesnt charged. But the symbol on the phone say the is currently charging... with the tool batterygraph can i see, thats isnt true...
aso i can reconized that the phone is hot.. realy hot.. extremly when the sun does shine on the phone.. the only solution is for me, to hold the phone from time to time at the airstream or i let the phone down in to the footweel, where does the sun not shine and a airstream flow around...
The akku is the warmest thing. without the cover, it works better.. i thnk the akku has around 45°... when is hot..
tested with navigon..
Hm... that´s possible. I will try it the next time with holding it in the airstream... Maybe that´s the solution.
I've got an windshield holder (dunno the correct English word).
While I'm driving open with my convertible, I set the airstream to the windshield (demister setting, but without heat), to cool the Phone a little down.
(If the Car is closed, I usually drive with activated A/C at 19°C - 23°C depending on my mood and the frozen girl on my side )
My Phone never exceeded 40°C.
So, this really may be the solution.
BY shorten the middle 2 pins... do you mean "short circuit" by joining the pins together in some way.
I have the same issue - I have the car charger from my old samsung omnia but it doesn't charge the phone and using any navigation software drains the battery very quickly
Jepp, short circuit the both two middle pins, then it will work.
For information: I tested today the charging with power supply.
780 mA is the maximum what the X10 takes. Tested with empty Battery (in Idle Mode and Apps running + WLAN + BT + GPS). Same result.
So a 1000 mA charger is fully sufficient.

i had bought an FM transmitter for the iphone for like 10bucks... the charger is USB so i just use the sony's charger cable and plug it in and it works great for me when i use NAV....no problems here

Thanks for sharing your knowledge.
Great work!
What's your opinion about your battery drainage?
Do you really think that the phone, running at full load, will suck more than 780mA to prevent charging?
Or is it really an overheating prevention?
Something I realized today:
I drove around for about an hour today.
We had 31,5°C today.
The phone was placed in its windscreen holder directly facing with its backside to the sun.
I drove with closed top A/C at 23°C.
At the end, when I was at home, the App "TempMonitor" showed me 56°C at the battery, that still was charging.
On weekend I'll try pushing the limits a little higher.
Empty battery + Navigation + open top without any A/C.
I hope my phone doesn't melt away
