[Q] [Question]Evo won't turn back on.

I was charging my Evo on my computer today and all of a sudden my battery died. Now it won't turn back on. After the first attempts to turn it on it would only get as far as the first HTC Evo 4G screen, then it would turn back off. This happened about three times and now it won't do anything at all.
I also noticed that when I put it on the wall charger that the red LED light doesn't even come on anymore.
Does anyone have any idea what this could be or how to fix it? I hope it's only the battery, because I can replace that!!! But I hope that's it. I don't really have enough money to be buying a new phone right now.
PLEASE HELP....SOMEBODY PLEASE!!!
P.S.
I had just installed an app called "Juice Defender" about an hour before my phone died. It's an app that's supposed to make your phones battery life last longer. I didn't configure it or anything. I just installed it. If anyone is famillier with this app is it possible that this could have caused this issue?

Just pull the battery & put it back in, then stick it on the (wall) charger overnight. The battery's probably just super-dead.
If it's not fixed in the morning, take it to Sprint & let them test a different battery. If it's your phone they should give you a new one for free as long as you have insurance.

The battery is super drained, let it sit on the charger for a couple of hours.

It worked!!
I tried what you've suggested. I left it on the charger overnight. Around six, when I woke up, it still wouldn't work. I removed the battery one last time and put it back on the charger. Now, all of a sudden, the LED light came back on. It flashed on and off about six times and then it stayed on.
I'm really relieved. Gonna leave it on until it's fully charged.
Thanks for the info.
Just hope it doesn't happen again.

Well glad that it worked. Just be sure to when the Evo starts flashing the red notification light, you need to get it to a charger. If you're out and about, I turn mine completely off at that point.

[Q] Charging issue that defies common sense...

I searched here and google and found various charging issues but none quite like what I am seeing. The night before last, I plugged my A100 in before bed like I normally do and saw the power light turn orange. In the morning, I unplugged it without even looking at the LED because I just expected it to have charged completely. When I got to my car and turned it on, it was at 32%. I thought maybe I had something running that was eating battery or I didn't plug it in all the way overnight so it didn't charge. I plugged it into the car charger and went to work. When I got to work it was still at 32% but I didn't use it the whole time so I thought that was odd. I pretty much didn't use it the whole day since I knew it was low on power and I didn't have a charger at work. I got home and saw that it was at 28% so I plugged it in. About an hour later, I checked and it was still at 28%. Thinking that was odd, I turned it off and left it charging with it off for an hour. Turned it back on an hour later and still at 28%. I spent a little time using it while plugged in trying to kill off apps and things but it drained to 18% even though it was plugged in, the power LED showed orange, and the battery icon on screen showed charging (lighting bolt). At this point I started to worry that something was seriously wrong. I turned it *off* and left it plugged in all night after checking to make sure the LED was orange. In the morning, the LED had turned off completely (not blue or orange). I turned it on and saw that it was still at 18% even after charging all night turned off. I unplugged and replugged and the LED came on orange again.
So here is where it gets really strange.. I decide to go through RMA process since I'm still under warranty. I don't want my private data on it when sending it to them so I do a wipe. On a whim, I plug it back in after the wipe and guess what? It's charging! What the heck?!?! I had thought maybe I installed something that was causing problems but since it wasn't charging even when turned off, I figured it couldn't be an app. Can an application cause the device not to charge even in the off state? I thought maybe my battery stats had gotten corrupted so the percentage readout wasn't accurate but right after wiping the data, the battery was reading 18% just as before the wipe.
Any thoughts? Anyone ever see anything similar? My gut says to RMA it still.

Reboot the device.
It's a bug that happened to me on Honeycomb all the time with A100. (No longer happens on ICS)

Did you actually read the OP?

Yes, multiple reboots didn't help. No charging even when off. Started charging after wipe. Very odd.
So, after my wipe, I set out to see if I could get it to fail again. I loaded a couple of apps that I had loaded a couple of days before this happened and it stopped charging again. Unloaded each of those apps and still no charging. Did another wipe and still no charging. Conclusion is it's busted and just randomly charges on occasion. Sending it in for RMA today. Still very odd that it was reliably charging after that first wipe.

I myself am experiencing exactally the same problem. Any fix found?

Similar thing happened to me. The only thing is I didn't realize it wasn't charging until it was too late and the battery was at 5%. After it shut off, the only way i could get it to turn on was by holding down the power button and plugging in the charger. It didn't get to try a data wipe (didn't have enough time lol). I sent it back and they replaced the system board. Said it was not recognizing the battery properly.

I own two tabs, and one had this issue, the fix is actually quite simple. Let the tab die. No battery life at all. Then, when your sure its dead, plug it back in, and let it charge to full. I haven't had the issue on the tab since.

my charge is on 3% too, but no good luck for me. seems a most serius problem
thanks.

any news guys? I bought a old ACER A100 and only power on while it plug in, so I went ahead and changed the battary, it still does not get charge.

Is the happening on complete stock? Or a custom ROM, if so, which one.
Also, reflash said ROM if applicable, and make sure the data is wiped.
I like the drain the battery idea, although its risky, these tabs can brick if it gets below 10%, current/voltage act weird when its low and blow a breaker inside and keep it from turning on.

What percent does it show the battery at while it's on?

My tab has the charging issue, but it is self inflicted. It was dropped, which cracked the lcd screen. I ordered one after a week or so and replaced it. At this point is when the charging issue cropped up. It powers on only if plugged in, and will get to 3% charge no matter how long it is plugged in. It will also only show the 3% if the charger is unplugged. It will then run for a few minutes until the battery dies. Also, the orange charge blinks about one minute after the charger is plugged in.
I found a reference on the web that if the battery charge gets too low the A100 can't charge it. I also found references that people had this problem, and Acer replaced the mb. I took a shot on the battery since it was a lot cheaper. Still the same. That doesn't the battery was not the issue since it was an ebay battery. So for now I just use it in the living room, plugged into outlet. Works good for that.

Ha! Found my own post by doing google query. Wow, didn't know this thread was still somewhat alive. So, I sent mine back as I mentioned in my last post back in February and they took a week and sent it back to me completely untouched. Basically said it was fixed but the same problem existed. I sent it in after a wipe but I did configure my wifi access point before I sent. When I got it back, my access point connected immediately and it still would not charge. I called them right back furious and demanded they provide shipping back to them because they clearly did nothing. They finally agreed and I shipped it back. After another two weeks of transit and repair time, I got my tablet back and this time it appeared to be fixed.
So, flash forward to 3 weeks ago. One morning I woke up and the tablet wouldn't power on. Black screen but the home "button" would light up when touched and power button would light up when plugged in and such. After several attempts to reset by holding down power button and using the recessed reset button, it was still not responsive. Tried up volume (and down volume) while powering pressing power button.. tried holding down reset button while pressing power button.. all with no result. Submitted rma request and was immediately granted without review. Sent it in and after about two weeks, got it back and it appeared to be working fine. Just this past weekend (about a week after I got the tablet back), I noticed that it was 3% after sitting on the charger for 2 days straight over thanksgiving. ARG!! Looks like another round of RMA here. I have not tried wiping but last time the charging issue happened, it was intermittent for about 2-3 weeks getting worse and worse before finally never charging. I am now near the end of my warranty period and I worry that if I send it back now, they will just turn it around and say it started charging after a wipe. What a piece of ... this is? This will be the 4th times in one year of ownership. I've almost spent the difference in cost between this tablet and other more expensive options in time and shipping alone.
I will try wiping it and then running it all the way down. Although I almost want it to fail hard right now so I can get it RMA'd before my warranty is up.

Faulty Battery or Common Issue?

So here's my story.
Last night I left my HTC One X to charge when phone was off but the red light was on, it was at 1% before I turned it off. Wake up, I turn it on it was at 3%, I was calm, I did a hard reset first before panicking, then it was 40% when it turned back on (fast boot is unchecked), I let it charge, but instead it was going down than going up, reaching to 0% in matter of hours it turned off, the red light didn't blink, until I plugged it back in, the red light started flashing, I thought it was charging but leaving it after an hour it stopped flashing, I had to go to work, so I tagged it along with me, I charged it for after 2 hour the red light stopped flashing and it was solid red, I let it go for another 3 hour before I turned it on, now heres what happened.
I turn it on, it was at 2%, I restarted it normal (power button), it went to 14%, then I wanted to try again, so I restarted it again and it was at 11%, okay, so I left it to charged but it was going down than going up, i've tried other chargers like iPhone and my Asus, still same problem.
My phone didn't act like this until I updated to 1.28, previous was 1.26
Bad news I can't swap it due to bootloader unlocked, bummer. Im sure its a software issue maybe? Reading incorrect battery value or something?
Any help would be greatful!

P.S At the moment it stuck on red flashing light again...

Seems like faulty hardware.... I too. Had unlocked bootloader still relocked it n got doa as well. Try visiting service center

Pack it up and back to the shop.
DOA
Maybe you want to check out this

but then as I said before. DOA.

Have you installed a custom recovery? The phone can't charge when turned off/in recovery at the moment (if you have installed custom) - only when booted into rom or on splash screens.
It's the first bug recovery devs are working on
M.

You seems to have a faulty set.
Do a 1-1 exchange if you can.

[Q] Bricked phone or battery?

Hi,
So my girlfriend just got given a used HTC Desire by a friend last monday. It was locked to Orange. Like all android based devices in this house, the first thing I did was unlock all the various bits, flash a decent rom, update the radio etc. and all was working fine all week including the battery dying totally at least once.
On friday, she had to do a 22 mile charity bike cycle for work (chump) and after she got home, she spoke on the phone for a while. Then the battery died. Now it's foobarred.
When I put it on charge, light doesn't come on straight away (hinting usb-brick)
Eventually the light comes on and goes orange.
It then goes green
When I press the power button, the green light goes off and NOTHING happens.
I can't get it to connect to the PC at all.
But since I can't boot it, I can't get into recovery, I can't get the PC to see it so can't use ADB.
I've tried all sorts of combinations of removing the battery, leaving it charging for hours, leaving it with the battery, sim and microSD removed for hours and can't seem to get any life out of it.
The phone looks fine, the water indicators are all still white. My only ideas aside from some catastrophic failure on one of the boards is maybe it's the battery that's shorted itself or something. Does the Desire turn on at all when plugged in with a fudged battery?
Anyone else had a similar problem? Any ideas on how to fix it? Phone or battery?
I'm trying to hunt down someone with a HTC Desire at work so I can test their battery with it - is there any chance this phone could make an expensive paperweight from another battery too?
Thanks in advanced.

Hi.
Maybe the battery, in his last breath, overcharged some circuits and burnt them. But I hope not for you. If the red light/green light works, it means at least that some of the circuit is working so continue your chase and find yourself another battery for testing.

Try and test the battery with a multimeter just to be sure ! Also what about charger was it original htc one ?

Did you ever sort it out?

Did you got this solved? I've got myself a new phone (giveaway ) and gave my Desire to my wife. I could flash another hboot and back to cm7 without any issues, she configured her google acc etc and put it onto charger over night. But it didnt charged. On yesterday morning it then died cuz of empty battery and dont come back now...

[Q] No power, no charging LED, no Fastboot

Howdy, guys.
I've got my One rooted, unlocked, and was running a CM10.2 nightly build. Everything was working fine until yesterday, when my battery started to rapidly discharge. I woke up with 100% battery, and after about 15 minutes of playing music it was down to 30%. I recharged it and started noticing rapid battery loss, about 10% per 15 minutes when the phone was idle.
Worried that this had to do with my ROM, I flashed the Eclipse Google Play Edition v1.2 ROM. However, the drain issue continued. I decided to let the phone fully discharge, then try powering it up again.
When it was fully discharged, I tried plugging in the phone. No LED came on and I couldn't turn the phone on. I've let it sit for over 2 hours now with the same result.
Some posts with similar symptoms have mentioned plugging the phone into a Windows PC and experiencing the "USB device plugged in" sound alert. I am not having any such luck, and what I currently have is a very aesthetically pleasing paperweight with no function whatsoever.
Has anyone else experienced a similar issue, or found a fix?

none
I would take that back to Verizon were i you, sounds like a bad battery to me, chances are remote that it's the phone/hardware/software. they have to repair it despite the fact it's rooted, they probably wont even notice lol
Were it me, back to verizon we go

Last Sunday, listening to music with HTC One (bought on Sep 11) on the charger, it suddenly went dark. Would not reboot, no charge light either. Went to a VZW store, they're shipping me a warranty replacement.
I wonder whether my habit of leaving it charger-connected whenever it's sitting on my desk (i.e., way beyond the fully-charged point) somehow stressed the battery (or the charging circuitry) -- though that habit never impacted my two previous HTC models.

When you hold Vol+Down and Power do your home and back arrows blink? If so, point the phone sensors (the two on the front on the left hand side) into a bright light. Then hold down Vol+Down and Power. It should boot. I'm not sure why. But it worked for me today after installing a custom recovery. -shrugs-

I've got a replacement being shipped to me, and I'll send them the old one when it comes in. Currently using an old Samsung Stratosphere as a replacement, I was just hoping there'd be an easier fix or something simple. Thanks, though!
