Internal battery is very low!!! Need Help

Hi,
My wizard main battery (wiza16) was very low and the wizard stop with a message “The internal battery is very low”. After coming back home I have tried to charge but it is not taking charge and didn’t turn on anymore. I recently bought a new battery (wiza16, 3.7 VDC, 1250 mAH) thinking that it will work again but still the same problem, wizard is not taking charge or turn on.
Can anyone help me?? What can I do to start my wizard? Do I need to change the tiny little battery (which is inside the wizard)? Kindly help me.

Wizard service manual
Hi,
See if when you connect the power plug the led turns red, if yes....
If Charge light is red when plug in AC adapter, it means the main battery is not charge enough and can’t power on,
You just need to continue charge unit the light become Amber
If not, i think you have a problem.
Check if charger its working and if its pluged.

Wizard Battery discharge completely
Hi,
Thanks for quick reply. there is no light when i connect my wizard with PC. I don't have the AC charger, I have lost that for long and was using my PC usb to charge. trying to get one AC charger.
There was no problem with my wizard, just can't turn on after it's battery discharge completely. Even the new battery couldn't turn that on.

You'll need the original charger if the battery has complelty discharged as it will only charge from the computer if the phone is powered on.
This happened to me before.
There is a trick to giving the battery a quick charge which will give it enough juice to boot the phone up and allow it to charge from usb. its not recommended but works.
You will need a spare usb cable, cut one end of, strip the wires back and connect the red wire to + and the black to - on the battery, only do it for a short period, about 30 seconds while conneted to your computer.
You may need to give it a few 30 second bursts to give it enough juice.
Pop the battery back into the phone and switch it on while pugged into the PC
Took me a few attempts to get enough charge in the battery for it to boot up.

Wizard battery
You can also use a 9V battery to jumpstart your battery. But then you have to be more careful. I connected the 9v battery to my Wizard battery for about 15 seconds, then tried to start up my device. If not successful I started again with 15 seconds jumpstart..
But you can find more information here in the forum: just search for jumpstart or something similar....

Wizard Battery discharge completely
Thank you all for information. 9V battery method didn't work for me. Looking for AC charger online and get a link (http://www2.dustin.se/pd_5010073700.aspx). Do you think this is the right one? If yes, then I can order.

yea that's the right one but if you have a friend with a ppc or maybe a razor you can use there charger most ac adapters are starting to use mini usb just a way of saving some money even though having an ac adapter is good
could also try and get one of those usb plugs that you can plug up to a wall and plug in a usb cable into the slot
but don't take my word for this wit hmy wizard i haven't had it shut all the way day
if anybody can verify this would work

AC charger not also working
I have got the AC charger yesterday. When Connect the Ac charger first time the red light on my wizard showed for just half second then dissappear. Still let that connected for whole night but no response.
Thank you all for help.

@Keland44, most Razr chargers dont work, they MUST be at least 850mA in order for the Wizard's battery to receive anything. The older Razr chargers are sometimes as low as 350mA, but the never ones are as high as 1.2A, so you need to read the label on the charger itself to be sure.

Yup that is about right,
If the battery is complelty dead, then you need to original charger.
If you have got the right charger and you get a red light and it goes off. your phone might have a problem.
This happened to my last wizard after stupidly trying to dry out the screen after getting it wet which stopped the touchscreen working (i was drying it out while the phone was still on) well my wizard crashed.
Took ages to get it back on but it was very unreliable then one day, it wouldnt go on and charger done nothing. Unpluging and pluging the charger in several times got a red light on.
Sometimes i could get it to turn on, the charger would charge for about 5 minutes then the phone would die soon after.
Your phone might possibly be bricked.

I Have Same Problem with my wizard
Yesterday my wizard goes died, i think the battery out
when i came home, i use AC Charger for HTC Universal, for 1st time its red light then off,
after 15 minutes orange light, i try to turn on my wizard and works but only in boot loader 5 minutes again its going off again
until now my wizard wont turn on
some body help

Now my phone won't charge

Totally stock (but i don't think it matters).
Plug the phone in, orange LED comes on.
Hold it or place in on the counter five seconds later, LED is off.
Had the phone since 6/4.
Anyone else having issues?

Are you using the AC charger ? I have two Evos and one of the chargers does what you are describing. The orange LED comes on and then goes off after a while and the phone stops charging. Does it on both phones, the other charger works fine with both usb cables.

Are you using the USB charger with a computer or laptop or plugging straight into the wall with an AC charger?
This does make a difference because if you are charging with a USB + laptop combination you could be suffering from the computer going to sleep and disabling the USB ports power to conserve laptop battery life. If you are having the issue when plugging into the wall, try plugging into a computer and selecting the "Charge Only" option when your USB debug comes up. Once it does this, allow it to charge for a period of time and then turn the phone off, switch to AC power plug and see what happens.
Perhaps you had some kind of over voltage spike on the charger through the AC plug. I could see it possibly tripping something in the phone to stop taking charge to protect the handset.
Also make sure if you do use a laptop, use a USB 2.0 or better port. More power and faster connection. Gotta love it.

Your charger may not be sourcing enough current anymore (for whatever reason). I have seen the exact same behavior with USB car chargers that were only sourcing 100-150mA.
Have you tried plugging the USB cable into a modern desktop PC? (Some laptops have reduced current ports, so a desktop is a safer bet)

Its definitely a current issue. I tried to charge my phone using my bluetooth headset's wall charger, but I got the behavior you are describing. The bluetooth headset's charger just doesnt put out enough current.
Are you using the charger that came with the phone? if so, you may want to exchange the charger...

im having the same problem when i connect it to my desktop, it sees it for about 2 secs n then disappears. My computer at work has no problem seeing the phone. i wonder if i need a driver or something for my usb ports, anyone have any ideas??

Probably not a driver issue, but that that rail from the power supply is either undervolted (say 4.6V instead of 5V), or can't provide enough current (amperage) or both. If I recall correctly, the Evo needs 5V @ 1A (+/- 3% tolerance).

Phone not charging
my phone has been charging fine since I got it... even been using the night desk clock app while sleeping at night for the alarm with it plugged in... everything was good...
With my phone about to die today, I plug it in to the wall charger, the led/batter indicator shows that it is charging... then POW.. it says I have a low battery and it needs to be plugged in... WTH??? it is plugged in!
The only thing I did today was flash the new boot.img for the cap fix over in Toast's thread...
Weird thing now is that I took my hero battery and put it in my EVO, plugged it into wall charger, and it stays charging... So, I put my EVO battery in my hero, plugged it in, and whola... it's now charging...
Please help as I am baffled.

that's your problem right there. that custom kernel is known to have charging issues.

I'm having the same issue with my car charger consistently. Plus my AC charger less consistently. For example, I'll go to bed and plug it in, the next morning I wake up and see the phone is at 80% charge and isn't charging. At some point over night, it gave up. This is with the stock charger too.

X10i not turning on / charging

Hi guys,
Suddenly facing a strange problem since last night.
My x10i was running out of charge & i connected to the comp to charge while i was working. I noticed the charging speed was extremely low, so i restarted the phone to see if it would help. Did not.
Thought there is some problem with the cable, used a different cable as well, but no use.
The slow charging had stopped and eventually the phone died.
Tried connecting to the socket & charging, still no use.
The red led blinks when i connect the phone to a charger via the usb or the socket.
needless to say the phone does not even boot up now, obviously for no charge...
any ideas wat maybe wrong or wat i could do ?
please advice

Have you tried to let it charge for some time in off mode? As long as your battery is not dead, and the phone get the right voltage through the USB connector it should charge in an "emergency mode". This is a slow way of charging, but allows for charging without any electronic circuits to monitor it, it is not the same as the charging screen that usually displays when you connect the phone while it is powered off. Usually when a phone is completely discharged it needs to be connected at least 15 min, sometimes a lot longer, before the electronics kicks in, and starts the speedcharging.
My best advise would be to connect it to the mains charger, or a USB port you KNOW supplies power. Some laptops cut down on the powersupply to the USB ports when they run on battery. Let it be connected for a long time (several hours), and then try to power it on again.
If that does not help three things can be wrong
1. Somewhere the USB connection is broken, either in the cable or in the connector on your phone (or on the PC's connector, but that is less likely).
2. The battery is dead, modern batteries contain circuits that actually disables the battery when any given parameters gets outside the defined limits. This is to prevent the battery catching fire. On some batteries this renders the battery useless, and you need a new battery.
3.) The mainboard of your phone is dead, and hence nothing works, can be ruled out if you can borrow a battery from someone to test if your phone works then.
I hope a good and long charge can sort out your problem, that is the easiest fix, and it is free.

Hi O_K,
well, i have been charging (or trying to) the phone since it died last night.
i have used different chargers & different modes of charge (through the system & the wall socket) - no joy at all.
the LED blinks red a couple of times when connected.
Very occasionally, the SONY ERICSSON logo (startup) shows on the screen & it switches off again, back to the blinking.
So charging for a long time & through different chargers has not helped.
gonna try a different battery now to see if that can help.
Thanks for your response!

well, tried switching chargers & batteries.
The problem seems to be with the charging unit on the phone (USB)
with any charger or battery, wen connected the led blinks (like wen the phone is charging), but there is no charge happening.
eventually the phone dies, even if charging
any ideas?

There is a thread some where in this forum for fixing the same problem you have...I don't remember the exact name of the thread..if I find it I'll post the link here..Anyways what the guy did was
-Pull the battery out and connect the charger till the led turns green.
-put in the battery now and charge the phone...
and I think that was it.
Hope it helped..

Hd2 not getting charged!!!! Pls help me

Hi Folks,
My HTC HD2 Android not getting charged either by a wall charger or usb via my pc... i dont what happened suddenly it got turned off due to low battery and when i pluged it for chrging its not showing orange LED notification of charging. when its off and plugged in Orange LED blinked once and Phone got switched on. And when its connected to PC for abt 3 mins it will show charging and after that it shows discharging and battery drains when it shows it discharging . pls help me out coz i dont want to loose my Leo .
Thanx in advance,,,,

Check the pins at the phone which connects to the battery. Sometimes they are deformed and this cause the charging/not charging problem.
But... in this case I don't think this is the problem, because this problem should not affect direct charging from usb cable.
Anyway check them just for sure!

Thanks VDodi

Best way is not to let it run out
However, normally it will have enough charge left once it dies to boot up far enough to start charging. If this is not the case, then you have to cut open a USB cable and use the red and black wires to charge the battery. I have not had to do this and am unsure as to how to do it but there are tutorials. It seems simple enough.

Consider, as was previously suggested, a cable connection issue.
While you do not currently have the luxury of looking at your status icons, I have found that, on occasion, when I plugged in the phone to charge, the status icon indicated a USB connection, rather than a charging icon. Unplugging the cable and re-inserting the cable fixed it.
Note that new high quality cables can exhibit the same issue.
You have nothing to lose... Give it a shot.
Good luck.

Take out battery, plug chopped up USB cable into wall charger, use fingers to hold red to + black to -, count to twenty, battery in phone, phone into bootloader, real charger cable into phone and wall charger, leave 10 mins, reboot into android. (Can charge all the way in bootloader, but it seems slower than when android is running.)

By 'tutorials on how to do this' I basically meant your posts

As previously said if you're using magldr you need to be booted into Android before the phone will charge. You can try to warm the battery up in your hands to squeeze the last bit of power out of it to boot up. Or there are standalone hd2 battery charges you can buy from eBay that charge your battery outside of the phone, they're pretty cheap.

As Samuel said you can charge phone in bootloader. Just try!

Had to buy external charger
item # M00366 this charger was cheap has led's that change from red to blue as the battery charges and has a usb port so you can charge a battery in phone at the same time.
I'd been alternating tween an extended battery and the original when my HD2 started discharging while plugged in. same batteries and nearly a year of typhoon's excellent ROM progression then wham dead batteries....

[Q] Overnight: Charging to 100%, then discharging while still connected?

Hi there,
got a strange problem.
I plug in my N4 in the evening, it is loading up to 100% and there it begins to DISCHARGE (or in other words, stops to hold the battery at 100%) although still connected to the charger. In the morning I unplug the phone and have just around 70% left ... see attached screenshot.
Using stock charger and cable that came with the phone.
I hope this is not intended by Google? Running Android 4.2.1 Stock.

is this the only time it happened?

It is probably because of the charger. They definitely didn't include the best charger out there try another charger, you'll see improvements.

Thanks! Used my equipment (powered USB hub with another micro USB cable) from old phone until yesterday, and read about charging problems when NOT using the charger and cable that came with the N4. To see if that is maybe the problem I therefore unpacked the "stock" cable and charger - but it didn't solve the problem.
The most strange thing is, that it charges perfectly up to 100%! I would expect then that it stops charging to avoid overloading, but that holds the charge level at 100% until unplugged. I think this logic is not within the charger, but controlled by the phone itself (Software / Hardware Unit)?

Have the N4 about 1 week now and I realized this happening at least 4 times now. I'm usually plugging it in every evening and unplug it in the morning.

Its intended as a safety measure so it doesn't over charge when its 100 percent.... It's always been that way

Hmmm ... never experienced this 15 years mobile phones (at least 4 of them using Android and tons of different ROMs ...). What would be the purpose to plug in your phone in at 22pm, stop charging at 1am and begin the fresh day at 7am with again 30% loss of capacity? I would need to carry my charger stuff all day with me ...
As I said, I fully understand that it stops charging at 100% to avoid overloading - and also see the sense in this here -, but usually it should HOLD it at 99-100% until you unplug and not lose capacity while still connected to the charger.
Cheers

did you plug it into a USB hub that was plugged into a computer? that might be your problem. My N4 has issues charging from USB ports... it never holds charge properly.

This happened to me previously, ended up swapping my charger back to my Samsung OEM one and havent had the problem again.
Another time that this could happen is if you're charging via your USB port on your computer and you shutdown your computer which it will still show the charging icon but the status says not charging which could be changed by replugging the phone and/or having BIOS settings that enable usb power draw etc...

Just found this one ... maybe I'm not explaining my case very well, but it seems I am not alone ...

Yesterday I used the wall plug. All the years before I used a SEPARATELY POWERED usb hub. Even if the PC is shut, the hub provides power to the ports. Anyway, it doesn't matter - Charging is working perfectly on wall plug, usb hub, stock cable, non-stock cable ... before reaching 100% and phone disscharges. Picture in 1st post illustrates the disscharge while still "charging" (last bar at the bottom)

it's def. not normal. mine doesn't discharge, it can stay plugged in all night and it'll say 'CHARGED'

Exactly what I would expect! Now that I found the others on code.google.com having the same issue I think there was a batch of devices having it and that I might need to RMA ...

Well the reason why I was mentioning the charger (unless you've tested another one) is because I was using the original LG oem charger and for a while it would give inaccurate readings on multiple occasions. Example being I woke up (used wall charger) and it said 70-80% and the charge icon was still there but on the status it said 'not charging'. Another time was when it said 96%, unplugged and replugged and it charged to 100%. Then I use the phone for a couple of seconds and it drops down percentage again 96%~ and when/if charged it will say 100% again (giving a false reading).
I was thinking it was the cord because I used my bro's LG charger and it charged the phone 96, 97, 98, 99, 100 and not 96 -> 100% therefore the cord may have been the problem. Went back to my Samsung OEM charger and it has been fine since then and never had any discharging.
Are you using stock kernel?

I'm on 4.2.1 stock yes.
Thing is, that I'm not plugging it out! While being connected it suddenly starts to disscharge - Why the heck would you disscharge when you have a power source connected?! The "event" invoking the disscharge to me is the reach of 100%. Maybe this is a misbehavior of the overloading protection, to stop charging (as intended), but not restarting to charge at lets say 99% or 98% to get back to 100%. This would mean that when I'm using navigation in my car I would need to reconnectfrom time to time to trigger the charging again.

Yeah I know what you mean but its odd that I had this problem as well but disappeared when I swapped.
As for my USB/PC, that charges when the computer is on and off but when I turn it off, I would have to replug the phone to get it started again as it will have the same "charging icon" w/o it actually charging. My guess is that if the power source loses its power, even if its temporary it will stop charging. But when I using my Skyrocket a few months back I never had to replug the phone onto my computer to get it charging again but I do know that the computer will temporarily cut off power when you shutdown and bring it back to charge plugged devices. (didnt change any power states in BIOS).
So most likely it is something with the phone but it could also be a setting or some software error triggering a fail-safe or something.

I see definitely some issues in the charging logic in both of our cases here. You shouldn't have to replug your phone if you send your PC to sleep, as long as it still outputs the USB power. Since I would not expect the decision to charge or not to charge in the wall plug or in the USB hubs, I can only hope it is not a hardware problem of the charging electonic, but a software problem which could be patched. Also wouldn't I wonder if this has to do with the wireless charging option of the phone ...

come to think of it i had the same problem. charging from the PC when off via USB it would do the same thing as OP. charging through the wall works fine.

Well just found out I am maybe reposting the issue as I didn't find this initially ... similar (or same?) problem described here: http://forum.xda-developers.com/showthread.php?t=2031246
