Jasjar shuts down, doesnt power up without external power

I have an Imate Jasjar (1.12.38 WWE)
It is giving a rather weird problem. When the power is less than about 40%, the device shuts down (slowly fading screen) if any intensive program is run or multiple apps are opened. After this when I try to boot the device, it shows me the blue Imate spalsh screen and slowly fades off and shuts down.
However the moment I plug it into the usb port of my computer or the external charger, it boots up and works perfectly fine even if I remove the power, till it shuts down again that is.
Another way to simplify my statement could be that the device is showing the power status higher than it actually is. Which explains the booting up with external power.
Any suggestions as to how I can rectify this. This is really troublesome as the phone often shuts down while Im out and I cant really do anything except keep the device charged to the brim at all times to keep it functioning.
Another issue I have is that the device when connected to Windows XP via activesync gives an error "USB device not recognized"
I have tried using different computers and USB cables, but the problem is persistent. But if I keep it connected for long, it sometimes gets connected and syncs. The device has no problem getting charged due to the faulty USB connection though.
Any suggestions on this front?
Thanks in advance.

Sounds like you need to buy a NEW BATTERY.

OK, Thanks.
Any idea about the USB error?

I have very similar behaviour from my Uni (technically an SPV M5000 from Orange Switzerland), but somehow, I doubt it's the battery which is at fault.
I also see the powering down, with fading screen, and then refusing to come back up again (display fades out again on splash screen), but I've observed it with various levels of charged battery. It has happened at 85%( according to both the standard battery meter, and ilauncher meter) as well as at 30% and various levels in between.
If I plug in it, I can boot the device, and after that, the battery runs down normally. I doubt this would work if the problem really were the battery.
I've noticed that the problem arises most often when I'm accessing the internet, either by 3G or wlan. So far, it has never happened when I wasn't actively using the device (meaning I've never taken it out of my pocket and found it in this annoying state).
Any ideas?
Btw, I'm currently using Laurentius WM6 V7 ROM, but I observed the same behaviour with Ivans WM5 (I forget which version) before.

For the USB problem you could try connecting it and opening the device manager (right click My Computer, Properties, Hardware, Device Manager) and deleting the "Unknown Device" that pops up when this happens. Remove the cable, reboot.
This fixed it for me, but I had to do it again a few weeks later.
Oh, and a new battery is the other problem. I got one last week for about £5 from Ebay.

By the way, my Exec seem not to realize when will my batt full. I see 100%, and I wait for more than 1 hour later, but the LED doenst change green, it remains amber. What the heck with my fone?? My batt or my fone fault??

turns off and will not come back on for ages

hi
my htc touch hd has been a bit jittery for the past week. occasionally just turning itself off or having various hangups.
I have the Stock ROM on it and have not tried to do anything extra to it.
Problem is now it has gone off completely and won't come back on. Took the battery out for 15 minutes and it started briefly and went off again after the very first smart mobility screen.
any ideas?
hard reset if i can get it started or is it a more serious issue?
don

Sounds like you need a new battery.

Hi there,
i agree with stuntdouble, sounds like a hardware (battery) issue. Is your phone still under warranty? If so, HTC could maybe send you a replacement battery?
To diagnose whether it is a battery issue or not, please try the following if possible:
(1) Charge the battery to 100%.
(2) Disable from running or uninstall any 3rd party applications.
(3) Disable Bluetooth and Wi-Fi,
(4) Enable flight mode
(5) Set backlight to maximum settings.
(6) In the power management settings, uncheck any option that would set the backlight to turn off.
(7) Let phone stay idle for 1 hour and check battery capacity.
(8) If there is a loss of 40% or more, then this means that battery is faulty and needs to be replaced.
Best of luck.

My 2 cents
This should help identify if it's a battery OR hardware OR software issue
* Is your battery completely charging? (i.e the light in your power button should be green when fully charged)
* Can you access the Bootloader? If you can, will it stay there and drain the battery?
* Have you tried a complete Battery Charge Cycle?
Battery Charge Cycle (As I do it)
* Turn the device off
* Attach to charger / USB cable and charge the device until the light in the power button goes GREEN
* Remove SD Card and enter the Bootloader
* Leave the system powered on in the Bootloader running from BATTERY ONLY - the device usually does NOT charge from an external source while in Bootloader - Either way, just to be safe, disconnect all external power sources
I use the cycle every once in a while on ALL my electronic devices to ensure their batteries are being completely charged and completely discharged. It is my PERSONAL OPINION that ALL batteries suffer from a "battery memory". Google it.
(8) If there is a loss of 40% or more, then this means that battery is faulty and needs to be replaced.

- This is a good method of testing, however it seems the OP can't get the device to stay on at all, which is why I suggested using the bootloader. So no offence intended by posting similar steps. (I'm not a fan of cutting another man's grass LOL)

Ive been having the same problem as well.
The phone would randomly freeze or even shut off by itself and the only way to restart it would be to take out the battery and put it back in. Sometimes, it gets stuck on the "Smart Mobility" bootup screen and I have to take out the battery multiple times for it to actually boot up to the home screen.
It's been a bit finicky with the charger too. I would leave it charging for a bit and come back to find the phone either frozen or shut off completely.
I'm not sure if I'd be able to test if it were the battery if my phone gets moody and decides to shut off. How do you enter the bootloader?

(mine was not battery issue). The problem is corrupt file system on internal storage or memory card. After fixing the file system, I dont have this problem anymore.

how did you fix the file system? Would a hard reset fix the problem?

Take out memory card and do HR.
It should bring device to original HTC state... so yes, it should fix it.
In the meantime, you can check memory card on some PC...

Power Button Staying Lit

Is anyone having this problem. I have an a70 250gb when I push the power button it stays lit even in deep sleep. My battery drains completely overnight. I don't want to power off when not using for short periods of time.

I had the same bug as well with my 25ogb, but for some reason after a full reset it seems to be gone...
I thought at fist a program might have caused it, but i've reinstalled the same apps and i don't have this problem anymore..

I too recently developed this problem where the LED light stays on and keeps using power when in standby. I thought it might be some app I'd installed but thought it might sort itself out so after a week without improvement, I did a Reset, without result (except for losing another 32MB to the Swapfile). So then did a Reinitialise, also without result. To be clear, I didn't install any apps and still the thing won't go to sleep anymore. Any idea's?

Well looks like we're at a loss... I got the same bug on my a101. Battery drain isn't too serious though, but still it just boggles the mind.
Sent from my Supersonic Evo using Xda-app.

I have the same problem and it happened around the same time my USB port died.
I've been waiting until the shop where I bought it has stock again to return it for repair/replacement. I think this is related to the USB dying.

It's happening the same with my 101. The led stays on when it goes to sleep, even after stopping all the processes using the Archos OS Monitor tool.
After a reboot seems to work OK; the led turns off in standby mode after five seconds more or less.
I haven't used deep sleep yet.
Maybe some application is causing this?
I installed only a few apps and firmware is v2.1.08:
- Aldiko
- Angry Birds (of course)
- DroidWall
- ES File Explorer
- Google AppsWidgetsoid
- SiMi Folder
- Zuma's Revenge

Have you checked the right tab "Wake locks" in the Archos OS Monitor?

Yes, I did change to this tab once and the list was empty. It appeared and disappeared a process very fast, so fast that I couldn't read the complete name
Good hint!

I get this sometimes on my 101, but a reboot seems to sort it out, Its got to be a process or app running in the background I think.

The best answer on the ArchosFans forum was :
My gut reaction is that you'll see this happen when you have the USB host problem because that issue happens when the power regulator chip in the Archos dies. And nothing can be done other than an RMA with Archos.

I verified this and my USB port was indeed not responding, so I've swapped it at the store and the new unit is wicked

Re: Power Button Staying Lit (Possible Fix)
Ok here's what I did after checking that the USB port was not the issue(worked fine with a usb flash drive). Check the following location
Go to: Settings-->Location & Security-->Use Wireless Networks
Description lists it as "See location in applications(such as Maps) using wireless networks)
If it is enabled, disable it. I turned it off, went pack to my home screen Soft press the Power Button for Standby Mode and the power LED is off within a few seconds.
Worked for me, Hope it works for you

Yeah, I have the USB host problem too, and it does seem like that is the cause. Argh, I don't want to go a week without my A70. D:

Confirmed. Hell, didn't know that would work O_O.
Thanks!

No luck for me - it was already off, and toggling it on then off didn't help, even after a reboot.
Nothing in the wake-locks list, and my host USB port is dead.
I see an RMA coming.

I really hope you found a solution. Ive been looking an answer for this annoying problem for 6 months!
Ive read almost 50 threads in differents forums about this problem but no solution at all.
- Tried changing charging port. Cost me a few dollars but no solution.
- Tried USB debugging on and off from developers menu.
- Did MTP+ADB option in *#*#0808#* menu.
- Turned Low Battery Dump "on" in *#*#0808#* menu.
- Tried 10 or more different original Samsung cables.
- Upgraded PC USB drivers.
None of them worked for me.
Hope you have made a progress.

I've accidentally repaired the USB functionality of a sm-a510fd with that defect, but don't know the exact steps. Try this.
1. Drain the battery until it becomes unusable.
2. Use the power button. The device will fail to start (with nothing on the screen).
3. Hold volume down.
4. Insert the charger. The screen turning on takes longer than it usually does.
5. The device should indicate that it is fast charging?

Maybe I did something different, such as pressing volume up, or holding both volume down and power. Or volume, power, and home. It's the last thing I remember doing before seeing it fast charge again. Odin and fast charging simply didn't, within at least a year of trying different cables, and chargers offered by others. The shop I bought it from cleaned the USB port but it didn't work. The fast charging works today, and the Odin flash worked.
The context was that I have replaced that phone, so I tested a few things on the old one that could brick it or damage the EFS. If it happens, I could load the backup on TWRP. If TWRP becomes unavailable, that's unfortunate. The phone didn't have much value anyway because the USB functionality, power, volume down, microphone, speaker, battery, etc were defective, many cosmetic defects, and the phone was permanently rooted. The SIM 2 tray's front broke off, the SIM became inaccessible (I have deactivated that SIM). Wiped the cache,data,internal storage on TWRP, before testing. I left the phone on. Battery went to 0%.
These are what I remember doing(might have done), most of these could, of course, brick the device, damage the efs, or permanently damage the hardware. Not in any order. I don't recommend anything below unless you have replaced your device, try different button combos, like the ones above.
Left the device on for ? days. It did not pass the new year.
Soundalive, Adapt, SecurityLogAgent were debloated.
*#9900# > SilentLog > whatever is on the screen. (Not 9090, the RAMDUMP (ON) could resize and damage the EFS partition!!!)
*#9900# > CP based log.
*#2683662# > DSP Log on, RmPC log on, RF log on (3).
*#9900# > Debug Level > high. Device rebooted itself.
Took a look at the logcat -b radio, it got more verbose. Cellular related, and there's hexadecimal that I was too lazy to decode.
build.prop dev.silentlog.on It set the option on, but with no effect? I don't remember if I had checked /data/log.
efs > factorymode > on, maybe? It didn't change anything, probably did not do this.
build.prop ril.OTPAuth=true
build.prop ro.build.type=eng It didn't work. Setprop... it didn't work. Reverts back to user.
The power and volume down... against the rounded edge of a table. Did not use force, it got those buttons unstuck(power permanently on, volume permanently off). Power button sometimes presses itself, but at least it isn't (almost completely) permanently like the way it was. Of course it could get rust all over the other components, get the accelerometer stuck, get those buttons permanently embedded, etc.
Turning both microphones towards the earth's gravity, inserting the SIM pin, then spinning it got the microphone working again. I don't recommend this. "OK, now only the USB problem is significant".
Set *#2683662# logs to the defaults (all off except RmPC), *#9900# debug level low, load backup in TWRP (data,system at least). And then the phone was left on at the lock screen.
Found it with a dead battery. Fast charge worked again.
I then flashed stock Nougat on it, then it got rooted. Gave it since it's no longer my main device. The recipient is afraid of it for some reason. Offered an underclock because the device gets hot while under load... nope. Guess it's the power button being odd sometimes. The speaker remains muffled & the sim 2 tray is stuck. But for now, I still have access to it after asking for permission, to copy & look at system files.
The battery is old and shuts off quickly below 15%.

You could try hard reset. If that doesn't solve then replacing usb port maybe only option left.

Samsung Galaxy S7 Edge Not Turning On

Hi people.
So i'm having a problem with my S7 Edge and i don't think it is common. A few weeks back I was using my phone and it would suddenly turn off and the battery would be drained too. After this first incident with the problem it happened more often, and the phone would start doing boot loops to the point where the phone just froze and turned off. When these problems occured it will usually need to be a problem where I do a safe boot (Volume up, Home button and power key), and everything will be fine (or to charge it if the battery drained), but recently, the phone just didn't work at all, to the point I waited for the battery to drain (10 hours), and try charging it, nothing happens.
So firstly I was watching a video and checking my CPU/Battery tempretures to see if that was the problem (the tempretures at the time were around 31 degrees), and mid way through the video it bugged out through the audio in a high screech and turned itself off.
I tried turning it on again but no response to the screen, i tried safe booting it, or every alternative booting option, it did not work at all.
Here is all the diagnostics and repairs I did, but no luck:
- Tried turning it on
- Different boot options (Volume up/down, Home button & power key)
- Cleaning the port for moisture detection
- Replacing the battery for a new one (Genuine one)
- Doing all of the above, with it on charge
- Connecting to a PC, but no detection
One positive I found was that when i put the phone on a wireless station, it would change colour to show that the phone is charging. I have however took the wireless out of the phone as it was in the way of the battery, and safely in my draw.
Before this final fault happened, I did do a recovery to a previous Android version, just incase if it was a software fault, but it wasn't. The phone is not rooted and I had it since September of 2016.
Is there any alternative options to do? As i'm running out of ideas to do as every solution on the internet is to turn it on, which i can't whatsoever.
The warranty is voided also as there is a crack on the screen lens, and it's way too much to pay for a repair.
I need some explination of why this is happening, so I can go in the right direction and not to waste money if i was going to a repair service, or purchasing the parts for myself.
Any help would be highly appericiated.

Check your installed apps to see if there any viruses on your phone. All you said are signs that your phone might have a virus (check how to remove it here: https://www.unlockunit.com/blog/how-to-tell-if-your-phone-has-a-virus/
However, there is a chance that you do not have any viruses on your phone, but at least you have to isolate this possibility.
Did you recall installing any app prior to this behavior?

This may be the case, however i can't turn on the phone at all. I tried every possible reboot possible, download mode, bios mode, safe boot, reboot, but nothing happens unfortunately. Unless i can do it whilst it is turned off, i can do something. I have a PC if i can do anything else with it.
I don't think I have installed any weird apps on the phone.

sounds like a brick to me. Not a lot I can thing of you can do.
If you place the wireless card back in does it boot?
IT sounds like you've messed with the internals, so possible you damaged something?

I don't particularly think that I broke it from the inside as it was behaving the same before i opened it. And when i used the wireless charging, it will only indicate it was charging or getting detected on that charging pad and not on the phone regarding a red led, or the charging icon

Have you tried holding volume down + home + power for 15 seconds and try turning on the phone again?

As mentioned in the description, I have unfortunately
