i believe your phone always charges at the same rate unless you have bad cells in your current batter, which you most likely dont
my g1 also does the same thing, this is because your phone is using 3g (or edge depending on connection) as well as wifi at the same time, for heavy data traffic. This, along with other processes running on your g1, cause the battery to die quicker than normal usage. The only thing id suggest is to turn off wifi, and aut sync and so on while using wifi tether, also turn your screen off while tethering, basically anything to limit the power consumption of your g1 to a minimum. But even then, when downloading large amounts of data to my netbook, my g1 still does die, its a slow death, but its inevitable for me.
Same thing with my phone, so it's not isolated. I think it's due to a known problem of the battery not reporting the correct level. I have found that a reboot or shutdown and reboot usually works well, also, I don't know if it's related or not, but leaving the phone sitting on a well ventilated surface and having it lcd screen down seems to keep it cooler and the charging normal as well. I hope the battery level thing gets fixed soon.
Wootroot pretty much said it all.
So is there a usb tethering app other than pdanet? Pdanet seemed pretty slow when I used it b4......
Has anyone managed to charge their HD7 while it's powered off?
As soon as I plug in power mine boots up and if I try to shut it down while charging it boots up again.
Same issue here
Well all my HTC devices did it. HD2, TD2, Orbit, Orbit 2 and so on so on.
It is not an issue, software is controlling charge.
the tp didn't do it .
My Touch HD didn't do it.
My HD2 did NOT do this how ever my HD7 does this lol
I just pluged in my HD2 and it boots up ASAP. If I switch it off it stops charging until I boot it up.
I'm finding this issue really anoying, i like to charge during the night whilst my phone is switched off just like i did with my HD2 every night! Really needs sorting.
Just turn on airplane mode and put it on silent.
I discovered last night that the HD7 won't take charge via USB from a powered-down PC. I know the ports are still powered while the PC is off, as my Touch Pro used to take charge overnight.
Wondering if this is a hardware or software issue -- or some weird anomaly of Micro USB vs Mini USB.
my hd and orbit didnt do it but HD7 does as you saing
This probably has to do with the fact that windows phone 7 will perform a wireless sync with the zune software 10 minutes after being plugged into the charger, so the device needs to be on.
Sent from my PC36100 using XDA App
So two key events happened with my phone - the replacement battery I ordered finally arrived, and I also crawled out from under a rock and flashed the ICS partition and pengus77's CM10.
I was advised to calibrate the replacement battery by charging it from 0 to 100 with the phone powered off. So I streamed a random high res youtube video to drain the battery as fast as possible, then powered off the phone and plugged it into a USB port on my work laptop (a HP Elitebook running Windows 7 Enterprise x64).
The phone started charging (battery animation screen appeared) - and then my laptop started to install drivers. A few minutes later, I got a windows BSOD - yes the blue screen of death, not the black screen on android.
I initially thought something else caused the BSOD, so I left the phone plugged into my laptop and rebooted. As soon as my laptop got past the "starting windows" screen, it BSODed again. Didn't even get to the "Please wait..." screen.
Tried to reboot again - BSOD before getting to the "Please wait..." screen. Finally I suspected my phone was the culprit, so I unplugged it. Another reboot - it successfully got to the "Please wait..." screen, and then I plugged in the phone (still off), triggering a BSOD in under 10 seconds, before I could even get the field to input my password.
Rebooted with the phone plugged in but powered on this time, and my laptop fully booted all the way, no BSODs. But if I powered off the phone and plugged it in, BSOD! Looks like I'll have to wait till I get home to my AC charger before I can calibrate this battery
This is quite strange - I never had any problems like this on the old GB partition, if I were to plug in my phone to the laptop with the phone powered off.
Has anyone else experienced such an issue before? If it helps, my work laptop is a corporate machine so I don't have admin access over many of its functions (though I can still install and uninstall programs like normal), and it's loaded to the brim with corporate bloatware, and it's possible these properties contributed to the BSOD.
Charging(forming) new battery via usb is never recommended to be honest
Most usb device don't provide enough power or stable voltages like charger designed for our phone
I personally never liked charging via usb(most usb hub's dont work properly also if they need to provide current to hungry device(our phone example)..
I have no prob's with that options and also using custom battery 1700mah...
I have no sod's on win but have read that people had problems and sods sometimes with usb charging...
It's hard to pinpoint exactly where problem lies,could be your low power usb on motherboard crashing your win or something else..
Hmm that sounds likely. I'm back home anyways and will use my AC charger to condition the battery.
I remember that on the old CM10 nightlies (before the call bug was fixed), the USB charger always BSODed my phone...
... an easy solution would be to start using a real operating system on your computer instead of windows

Believe me, I do - I use Linux as my main OS on my home computer, and only boot into Windows for games
However this is a corporate laptop that doesn't actually belong to me and I can't meddle with it like that.
I am experiencing some stability issues on Windows 10. Sometimes the system randomly freezes (screen stays on, but no reaction until hard power off) or does not wake up, while being charged with Windows running. Other times the system runs perfectly for hours. I am not experiencing any problems under load.
My problems are not load related, and I have disabled the fast boot option in energy management. As there is no blue screen, I cannot find any info on what is causing it. It is a clean install. Except the two drivers for the cameras, all drivers are signed and either downloaded from Windows Update or gathered by scanning the Win 10 driver folder that has been uploaded on this and the techtablet forums. The graphics driver has been updated with the most recent Intel version.
What are your experiences with Windows? Anyone experienced something similar or is there a known faulty driver?
Other things I tried:
Error check on drive
sfc /scannow
Windows and this tablet have some problems... my experience http://forum.xda-developers.com/x98...-2048x1536-t2913035/post63550338#post63550338
They also occur when idle, when using the tablet everything is fine, problems are not easily reproducable and I did not find anything valuable in the event log, so i gave up and live with it.
I reinstalled windows, tried different bios versions, drivers... energy options, nearly everything I could think of^^
Wasted a lot of time, I now hard power it off instead of letting it "sleep" or whatever it does, I guess some driver is faulty with the windows deep sleep aka "connected standby".
I narrowed it down a bit. I kept looking for driver updates via Windows Update and examining the different powercfg reports. (my thought was, if the driver or app misbehaves in connected standby, it is not good). Now the system seems stable on battery power and connected standby seems to work as expected.
I do have problems while connected to the charger. The device will not wake up after a longer time if it goes to sleep while charging. I also noticed that the sound driver seems to alter its behavior when power is connected, so testing now with volume=0. (some well known problem with the audio driver on other tablets)
My fresh install of win 10 (1511) just slept to death again. This time there was an entry in event log. LockApp.exe crashed after waking up, so silly, eventlog is full of errors that shouldn't be there on a fresh install.
One question, does shutdown work for you (win or android)? Mine seems to power off, but it isn't really off. Drains battery and before you can turn it on again you have to hard power off (even though it looks like it is off).
Positive thing about fresh install of win 10 (1511) is that wlan works out of the box, also some more drivers are downloaded automatically (but seems not the ones that cause problems^^).

I did not switch it off often enough to reach any conclusions. Seen it fail when shutting down from Windows several times, from Android things seem pretty stable. To test, I attach an USB lamp to the OTG adaptor. When the tablet shuts down it turns off USB power and the lamp turns off.
Hi guys, I have a huge problem.
Currently I'm on vacation in Croatia, where it's around 38-40 C every day. One day I had to log into an unsecured wi-fi. I know, i shouldn't have done that but it was urgent. Well, the same night (while charging) my phone turned off itself and I had to turn it back on on the next day. It worked the whole day until I opened the camera. Suddenly the phone went off and I wasn't able to turn it on. At first I thought the battery has drained so I plugged it into the original OP charger (dash). It gets warm while charging, but the LED is not turning on. After an hour of charging I still can't turn the phone on. Not even after a charging over night. There's also no vibration after holding the power button, neither holding the power-button for 20 (or more) seconds . I can't even get into recovery mode by holding volume-down and power.
I'm on original Resurrection Rom.
Is there anything else I could try? Could it be that some hardware is damaged (overheated)?
Since I'm on vacation there's currently no way for me to do any kind of unbricking until I find some phone-repair service.
I'm not a pro, but Im pretty sure the problem occur on the hardware side since the phone is not taking the charge and no vibration
I once had an Android phone (not 3t), the same thing occured, the phone I had had some hardware damage near the battery so I experienced the same problems you listed, ended up getting a new phone
Overheating is probably not the issue, at least not the 40C air temps you mentioned. These devices can probably something like 60C (internal temp at CPU or battery) before seeing any damage. Lot of folks live where it's just as hot as where you are, if not hotter. So I have to think the device is designed to work under such conditions.
Try holding the power button longer (a minute or more). I don't know about this device. But on my old HTC M8, there were instances where the phone powered off by itself. And the power button needed to be held over a minute, to make it boot. Although no charge LED is concerning.
Mine did the same a few days ago, was tethering and the phone just shut off. Buttons didn't work, no vibration, no charge LED, no anything. Thought it died but after plugging it into a PC it was detected as QHSUSB_BULK (hardbrick).
But it turned on normally after a minute lol.
Hallo. Mine also crashed. I was in the sunset playing game and taking pictures. Then phone suddenly got so warm and lagged, It turned off itself. No reaction. I connected into charger and then turned on hopefully. I think you must take care, because it has metal body and easy heating, and when heating it's lagging and not works good
My opinion is that it's overheat problem

You will see Qualcomm download mode message (QHSUSB_BULK) whenever the device is powered off. It needs to be powered on, at least to bootloader (or recovery or OS) for the PC to connect in any other way.
Update
After 3 days, it finally turns on and charges as expected. Don't know if it has to do anything with it, but i let it in the charger for 1 day.
but now another problem occured.
every time I press the homebutton the phone crashes and goes off. this only happenes if the fingerprintscanner is not requested.
i.e. unlocking phone with fingerprint, does not crash, but... pressimg homebutton to go back to home screen crashes.
