HTC AMAZE Keeps shutting down

Every day my HTC AMAZE 4g keeps shutting down multiple times a day, is there a fix or should I request another one from T-Mobile?
Sent from my HTC VLE_U using XDA
I'm having the same issue. 4-5 times a day it'll just shut down and then take it's sweet time rebooting. Im rooted running stock 2.3.4 trying to upgrade to ICS which kind of tumbles into another issue. I'm trying to do the update to ICS via the OTA update and when it powers down it just boots into the Bootloader screen. My status for my bootloader shows <RELOCKED> followed by <SECURITY WARNING>.
If anyone could shed a little insight that'd be aces.
The random reboot issue seems to be battery related from what others have stated.

Why don't you update to ics manually? And as above has stated contact HTC tell them you have defective battery.

I can confirm this. I called t-mo and they basically told me that I'm SOL on a battery replacement. So, I got the Anker 2 pack on Amazon for 30 bucks, and I haven't had a reboot since.
Had the same issue. Called HTC tech support bypassing T-Mobile since I use a different carrier. HTC sent me a replacement battery.

I guess I should call HTC as well. I thought about calling them, but the Anker has a big better so I didn't mind plopping down 30 for 2 batteries.
Mine shuts down also. Then when it boots back up it has 20% less battery -.- isn't that annoyin ? Lol

you have a faulty battery.
this sounds like a recall-type of deal here. i'm having the same issues with my oem battery. called htc the other day, and they wanted my cc info to replace the battery. i'd still have to pay for shipping the old one back to them. will try calling again, and see if i can get one for free lol

same thing with mine. went through 2 amaze 4g's and 5 batteries in 2 months. I end up buying a new battery once every 2 weeks.
One thing i know that WILL kill my battery is if i plug it into the outlet on an amtrak train. Every time i exit the train, its dead. Learned that the hard way.
I also keep the rubber case that came with it off. It happens less and less that way. I think it's overheating, since it was very hot out each time.
Hello guys,
I've also about the same problem, My Amaze is Asian version with JuopunutBear S-OFF and ICS Speed Rom installed.
The problem with my phone is that while its charging or in use, it doesn't shut down, but when idle for some time with no music application running in background, it shut down.
then it doesn't turn on unless you pull the battery for a while and re insert it,
Can anyone plz tell me what's the issue, is it battery or some culprit application?
Thanks
I had the same issue on my phone. It was due to the kernel issue .I flashed super wipe once & flashed backup again . Now my battery is ok & I found no rendom shutdowns anymore . try this if it helps you.

which kernal you're using now??
I used to had the same issue. Tried updating Android using stock, changing the ROM to a custom one (CM, Energizer, etc.), changing the kernel. nothing seemed to help. In the meantime, I bought a battery from eBay. Took about 3,5 to 4 months to arrive (yeah, **** me, I'm from Argentina). I put it on and VOILĂ€. Holy solution.
It is an Anker one, so it has more capacity also
I m using faux kernel v. 31

take the battery out and put it back in. Without turning on the device charge for 4 hours.
Turn on the device but let charge for another hour. This seems to have worked for me.

Turns off while charging

Hi all,
I've searched for an answer and couldn't find one.
My Galaxy turns itself off while charging and most of the time, I have to take the battery out to turn it on again.
Anyone else have this problem?
Thanks

First, caused by AC charger or USB PC or both ?
Your firmware version and rooted, mods etc ?
Have you tried a factory reset ?
Different chargers and cables etc ?
Sent from my GT-I9300T using xda premium
Only by AC charger I think. I've only got the one which came in the box.
It's a standard phone, not rooted or anything.
I haven't tried a factory reset, will try that tomorrow if it does it again tonight

op says his turns off WHILE charging, so yours and his isn't doing the same thing.
Actually, mine is doing that too!
This morning, it turned itself off while charging, then when I turned it back on it froze, and then when I rebooted, it turned off again with the blue light flashing.
I'm also finding that the screen when waking up is very temperamental to unlock.
I'm getting fed up now!

Hardware failure maybe? (I think the main reason is the AC adaptor was broken or something).
Have you try with another USB AC adapter?

I think it might be something to do with wireless being on. Sounds stupid, but when I have wireless on, I get the screen freeze and the turn off while charging.
Going to try the rest of the evening with no wireless and see what happens
Sent from my GT-I9300 using XDA
Well, I tried the wireless off and charged and it was fine. No screen freeze or turn off during charging.
As soon as I turned it on this morning, screen froze when it went into sleep.
Luckily I I have unlimited data!

Have you bothered to Factory Reset ?
Sounds like WiFi drivers though.
Flash another kernel would must likely fix it.

Did anyone get to the bottom of this? I just received my replacement phone and sure enough, phone switches itself off when wifi enabled.
Then I saw the *#0011# trick to turn off wifi power save mode.
Hi,
No, I haven't got this sorted yet. Still does it with me and now my wifi and data keeps dropping out!
Going to send it back to 3 and let them fix it. My friend as one and his is fine

The thing i mentioned above your post works but not sure if that's the answer.
Hi again,
Well I rooting and putting a new ROM on and, though it didn't switch off while charging, it does still freeze when coming out of sleep.
So I'm getting there!
Sent from my GT-I9300 using xda app-developers app
Try to check the temp when charging, I read somewhere that if the phone overheats it will shutdown automatically. About the freezing issue, try to do a factory reset first, maybe some apps that you installed are causing that.
If still the same, maybe its a hardware issue.
Hi again,
Sorry to keep going on about this, but the problem has been solved!
Basically, the new firmware update has sorted the problem. No turning off while charging, no freezing when coming out of sleep - its perfect!

Help! Weird battery behavior

Hi there ppl,
I was normally using my phone (web pages, twitter, etc...). Suddenly screen started to flash with something that reminds scanlines and after that the whole phone got a little bit hot, instantly, and finally it died.
I pulled off and put the battery back to find out that it was completely depleted... now it's normally charging... does anyone knows if this is a sign that the battery will die soon?
Update: More freaking stuff. I just spoke with my girlfriend, she owns a lumia 800 on the same network. The same thing happened to her phone except that the battery died for a few seconds and came back normally (without recharging)...
Cheers

Phone reboot problem

When I first got my GN2, I had an issue with it rebooting, this wasnt a huge issue as it usually only occurred once a day maybe every other day. I am now unlocked and rooted, running Cleanrom, and it still occurs occasionally, sometimes it won't even reboot it will just freeze my display will be off from not using it for awhile then I will pick up my phone and running to wake it up and nothing happens. My LED will be flashing blue though and the only way I can reboot is to pull the battery. Like I said not a huge problem because it only happens once every couple days. Does anyone have any ideas on what could be causing this?

You should have exchanged it. Rebooting on a stock device is unacceptable.

[Q] HTC One Suddenly Dead

HI,
I've been using this phone for over 2 months with no issues.
3 Days ago, the phone died while holding it and browsing the menu.
I thought the battery is dead as it had around 20% left.
Ever since the phone is not showing any sign of life. not even the charger LED turns on.
Can anyone suggest something that might work?
Is it rooted? Can you go into bootloader or recovery? If not, then send it in for RMA as I'm sure you have warranty
