Hi folks!
I brought a HTC Sensation on eBay, but until now, only the phone and USB cable arrives.
So i need to know if is possible turn on the phone only with USB cable and (wall) charger, without the battery.
Is it possible?
Does damage the device?
No it's not possible. You need battery

you pay with what? if you use paypal definitely you'll get you money back.
I wish modern phones were able to turn on without the battery, while plugged in, like the old phones used to. Dunno why they stopped, but it came in handy when your battery was bunk and you had to use the phone, even as a corded handset, for a while

Probably because it's possible to use more power than what is coming in, so they removed the "feature" for stability reasons. Using Google Maps for navigation with GPS on and the screen brightness all the way up can do this, and some people will even have bluetooth enabled to tether to their car stereo, draining the battery WAY faster than what a charger can push in.

Your right. There's also a chance of eMMC damage or data corruption/loss by loss of power. In the end, letting you connect a flash memory phone to a computer and switch it on without a battery will only hurt the device.
Btteries must have at least a 1-2% charge before the device can be powered on. Your sensation will flash it's amber LED to warn you if the battery doesn't have enough charge to turn on while the phone is connected to a charger.
Thank you so much guys!
I'll open a case on eBay and buy other battery.

I relay on tethering for all my internet needs (browsing and ps3) All of the apps available heat my phone up so hot that the moto logo on the battwry cover turned black and fell off. Already gone througj 2 batteries in 3 months.

You posted this in the wrong section.
However, if you've got the phone plugged in, you can remove the battery. You're killing batteries due to the heat and the constant charging. Lithium Ion batteries don't enjoy being roasted, nor do they enjoy being charged all the time.
Also, if the phone is getting that hot, perhaps you should place an icepack on it, making sure to put something between the phone and the ice pack to prevent the condensation/moisture from destroying your phone.
I'm assuming that you're doing "illegal" tethering, in which case, using it as your primary source of internet, I'd hope Verizon never gets keen to you or your bill will bankrupt you for sure.

Exactly... you might want to rethink your tethering strategy.
I keep my phone on the dock with a mini fan for the heat. I tried pulling the battery but phone won't boot without it.

Take the battery out after the phone is on.
you cant just take out the battery and plug it in, i just tried. i leave mine in the window and check on it every now and then, if it gets over 100 degrees i stop tethering for awhile, but i can play DCUO on my laptop for about 3 hours before i have to shut it down if its cold enough outside.

I've ran my phone without the battery installed quite a few times, never had problems..
You must turn on phone without charger plugged in, then plug in charger, then remove battery.

It doesn't work I just tried, followed your steps exactly. My Droid 2 shuts off and tries to restart but comes to a screen with a battery symbol and a question mark inside of the battery, basically the phone is saying " wait, where the **** is my battery". If all your guys' phone's work without the battery then mine is like the only one that doesn't.

Are you stock? if not what ROM do you use because I'm running Liberty 1.5 and I just tried it connected to AC power and it rebooted like what was said.

I think I was using a version of Fission ROM, but I don't remember.. I don't tether too much anymore since my work got wifi installed.
I noticed today while I was trying to get maximum charge in minimum time that after I turned my phone off and charged it, it automatically turned on. After I noticed this while it was still plugged in I shut it off again and much to my dismay it turned on again!
I'm on the HTC 7 pro, anyone else confirm this issue?

Phone will not turn off if USB charging/syncing; must use AC charger. Another alternative is to buy a second battery & wall charger specific to that battery; I have this setup for my Samsung Focus, but use it infrequently.
Would you mind testing something?
Turn off your phone, plug in the AC charger and see if the phone automatically turns on automatically?
Then if it does turn on again shut it down again while it's still plugged in to see if it turns on automatically again.
Thanks, I'm trying to see if this issue is unique to my device so I can report it as a bug.
Windows Phone 7 works this way. I was a bit surprised too, but the explanation from MS was that the charging circuit in the phone is software-controlled, and in order for that software to run, the phone must be on.
Yes, I know anybody with a modicum of software design experience knows how lame that sounds, but that's the "official" explanation. You *cannot* turn off the phone while it's connected to external power.
The good news is that while charging, the WiFi is left turned on, so if you have a WiFi connection, you're not using 3G data in this scenario. That was my primary initial concern (but not the only one).
Brad.
So since it's software controlled it must be possible to disable it through some option.
if you disable it, you will lose an option to charge the battery...simple as that
I guess this is yet another feature I enjoyed with WM that I can't (hopefully yet) enjoy on WP7.
I don't understand why you would make a purely hardware thing like charging into software...
Well, I don´t really undestand why is it such a problem, you can still turn the airplane mode on, this way there will by no cellular transfer, and put phone into sleepmode, if you do this, what do you think, by how much slower you would have your phone charged compared to turning it off? 5 minutes? Well that´s an achievement...
I wish I had two identical devices and I could run an actual test on this but I can only use my old TP2. I've always been under the impression that if your device is charging while it's off that it charges much faster than if it is on (consuming power) and trying to charge at the same time. It's always made intuitive sense to me that that's the case.

unless there is some sort of software based charging optimization involved.
couldn't find any info so i'll see if i can hopefully get some answers
been running my inspire using Existz's ICS rom via the ace hack kit. no problems. i went and picked up an infuse 4g and decided to use it. so had that rooted and running. yesterday backed up everything on the inspire and removed the sim and sd card started using them in the infuse. was still playing games and such on the inspire. here's were things started to act weird. plugged in both phone on the wall charger and powered off the inspire. well it kept rebooting in recovery. i'd go down to power off and it'd come back on. did this maybe 3 times and then finally stayed off. today went to show a friend that was interested in it and it would not power on. no led light, nothing. plugged it in and still nothing. put in the spare battery and no led light or anything. tried to put it into recovery, nadda. put the sim and sd card in thinking it may make a difference, nope. so i'm not getting any power.
any help is appreciated.

If the phone is not booting at all and even trying a spare battery is not showing signal of life, then take it to a service centre. When the phone is plugged is showing the led light?
No, no led light anymore. Unsure of how whatever happened happened.

Try another cable, maybe is failing and the battery just discharge 100%. Have you tried plugging it to the PC?

maybe the screen has issues. Are the capacitive buttons doing anything when you touch them?
No, buttons aren't lighting up either. Going to try some more different cords and try plugging it into my wife's mac book and see if that does anything.

I have no idea about that...but send an email to HTC to see what they tell you...
Try letting it sit and charge for a while second try to boot into hboot. I'm assuming that you rooted your phone so going through HTC for repair is not an option. I had a similar issue I ended up booting into hboot and then flashing a stock rooted img and starting all over with my phone.
Since your computer recognizes the device, did you try to send it a reboot command via adb?

No I did not. Not sure how to to do it that way, but I'm sure I can find out how.
After reading a couple threads where people have had the same issue, I left the battery in it and placed it on the nightstand. It started to vibrate a few times and when I hit power I get a solid red led. Will have to search and see what that means.
Sent from my SGH-I997 using xda app-developers app
It sounds like it could be a bad battery. Given the red light, what has me wondering in the vibration prior to you pushing the power button. It almost sounds like the phone shutting down from low battery, but you said it wasn't on.

Just a little note on Android phones. If you let them die completely they will not charge the battery from a PC or computer of any kind. The ports on a PC only provide 500ma max and it require at least 1 amp to charge a dead battery. That can only be accomplished by the wall charger that was supplied with the phone. If you are using another charger make sure it says on it that is can supply at least 1 amp or 1000ma any thing less will not charge a dead battery. Also note if the battery is completely dead, then the phone will not charge any way. The phone has to be able to power up and load the OS in order to charge. Androids use a software based charger that does not know how to charge unless the phone can boot and preload the the boot part of the OS. You may need an external charger the battery alone can be placed in or buy a new battery as they will usually have enough of a charge to get you going.
As the previous poster said, it sounds like you have a bad cable from the beginning and all you did is discharged it completely. Get a new cable and try the wall charger. If that does not work then spend 20 bucks and get a new battery.

vibrated a couple times when i was in bed. got up and hit the power button and just the red light would come on, nothing else. generally when i had a low battery the phone would boot up, then shut off. not in this case

well i have 2 batteries, 2 different plug adapters, 3 different cords and a car charger. tried six different ways charging from a wall adapter and flip flopped batteries as i changed cords and plugging it into the car charger. each cord and the car charger works with my infuse and worked with the inspire that day. battery was at 3/4 when i plugged it in. i guess could try a new batter, but i'm doubtful.
Hi,
Last year my girlfriend allowed me to root her Sensation to try out different ROMs and all went well. A few months ago however, she started to have problems while charging her phone.
If she plugs it in while the phone is closed, the orange LED flashes on/off at around a 2 second interval, instead of holding it's colour. Furthermore, it never changes to green to indicate that the charge is complete. When the phone is in this state, she can't turn her phone on either - she has to unplug it in order to turn it on. If the phone is already on, and she plugs it in, everything behaves normally.
Either than that, the battery seems to hold the charge normally and the rest of the phone still works very well.
I've tried searching for similar problems but haven't landed on anything similar or which may be helpful. It's really got me stumped to what could be the cause, and more importantly, how to fix it!
Would someone have any ideas?
Thanks!
Does the phone behaves in same manner if it's fully charge n switched off when plugged to the charger.does the orange led fluctuate.
The orange led fluctuate whn the voltage of charger is less and it takes times to charge try switching the charger means if you use wall charger then charge through pc and vice versa
Hit thanks button if you find me helpfully

We tried switching from wall plug to USB on the laptop and it does the same thing. However, we noticed that if the battery isn't completely drained, the led doesn't flash - it charges normally.
Would there be a way around this?
I'd pick on the odds that the LED light hardware controller is slightly faulty, but if its really like you said its nothing to worry about, right?

Hi,
greetings
this used to happen with me when i was on stock rom.
the problem is when the battery is completely drained it needs lots of voltage to get charge
for this problem i took my cell to htc service center and they replaced the adapter and the problem was solved
i think you must buy a new adapter or say a new charger i thing that must solve your problem of led and your phone will get charge as normal even with the battery completely drained OR i think we get wall chargers you can look at the picture in which we have to place the battery and the battery gets charged you justt have to put the battery.. this charger is locally available in indian market for 80 to 100 rs.. you can search on net for the charger this is really a good thing and is a universal charger chagers each and every battery here in india we call it as khekda (marathi word for carb ) charger
let me know if it does solve your battery
So, I've just gotten my G3 and ordered a spare battery as well. I went to swap batteries while plugged in, but as soon as I pulled it out the phone shut off. Is there a way to work around this? I'd love to be able to live-swap batteries (while the phone is plugged in, of course), and I know I'd probably need root access. Any recommendations as to turning off the shutdown procedure, as well as general advice about rooting, would be more than welcome. Thanks!

It's not really possible. I haven't seen a phone able to work while plugged in with no battery since before Android was popular. And that wasn't even a smartphone.
