Hello,
I have a HTC Blueangel with a somewhat novel approach to charging its battery.
When connected to the USB, the charge meter continuously _decreases_, something close to 1% in 5-6 seconds. When the meter reaches 0%, it stays there for a short while (20-30 seconds), then jumps back to whatever the real charge is. And start decreasing again. After the regular several hours, the battery gets fully charged as normally should.
The charging used to work normally a while ago, and I cannot figure out what (or when) did I do to make it act this way. Initially I thought it might be a software problem, tried a hard reset, but it's still happening.
It's running WM2003 (1.42), with radio 1.15. BlueTooth, IR and wifi are disabled, screen brightness is set to min, etc. so I cannot understand what is going on.
Normally it should not be much of a deal, because the battery really has charge in it. But the system believes the indicated meter, so when going really low on the battery meter, it decides to disable stuff like phone, SD slot, etc. trying to conserve an apparent lack of charge.
If I disconnect the USB cable, the charge meter appears to drain at the normal rate (regardless of what the _real_ charge is). All other battery-conserving features appear to function normally -- notifications at 20 and 10%, shutting down when empty, etc.
I do not have a wall charger, so I could only test USB charging. I do not have another BA available to test just the battery.
Any ideas as to what might be going on? Is it possible to fix it?
Thanks,
-Daniel
lol sounds annoying........what about reinstalling wm2003???
i am having a similar problem - using the usb charger while in the car seems to discharge the battery. nothing seems to fix battery drain problem - but on the cradle it is fine. let me know if you find anything on this one
Hi guys,
I was playin Temple Run and the battery was about 5% or however close to be fully discharged. Suddenly the display was flickering, or like something this. The phone suddenly powered off.
I tried to charge the phone with the charger in the plug, but after some seconds the animation disappears, then reappears in few seconds and disappears (about when the charger animation goes to the top for the second time).
The GN is connected to the PC, and does not power off: but the charger indication is stuck at 0%
What's happened? I doesn't made something wrong!! I used to discharge my battery often!
I also wiped Battery Stats in recovery, it does not helps.
The ROM and the Kernel are inte signature. I never made overclocks or something like this. Please help me
When I detach the USB cable from GNexus it power off (like when it's normally discharged)
EDIT: Suddenly the % went to 2%.
With lithium-ion batteries like the one in the Gnexus 'like' being charged. They do not have a memory like ni-cad batteries. Severely discharging or overcharging our batteries can physically damage them. If you store the battery for extended times, leave it at 30% charge.
As to why you experienced the freaking out from your phone, when batteries get low on charge, the voltage and amperage output drops. When your phone has a low draw, you won't notice this. Under high draw like gaming, it may not be enough to power your phone. Turn it off and plug it into the factory AC charger. Let sit for at least 30 min or so. Then try to power up.

Yeah. In 30minutes of game the battery went down of about 10%. Web browsing in 3G is less battery expensive
Your battery might be damaged if its acting up when it gets low. Try not to run down to zero.
zippity doo da.
Whenever you get a chance, plug that phone in.
In the car on the way home? Plug it in.
Sitting in the office? Bring your charger and plug it in.
If its under 70% that is. A small charge will always be healthier than 0-100.

i just experience the same thing i thought i burned out the phone home recharging it will help its look like it stuck on 0%
EDIT : its start recharge also
the way the screen flicker and the sound its made was just the scary
Please,anyone help me fixing my HTC One V. It was accidentally dropped in water,I turned off it immediately and removed the water as much as possible then I kept it in rice for 2 days.It is charging very slowly and it only turns on after plugging it to the charging socket.It takes 11-12 hours to charge to 60% and drains out in 3-4 minutes only. Please help me fix it.

Looks like something is draining your battery or your battery is broken. Open the phone and look for damaged components...

Thanks for the suggestion,Can the battery change will do the work ? I have taken it to the Service Center they said that they will have to look it if it's charging socket problem,and if it is then being its socket mounted on motherboard directly they will have to change the motherboard of phone and it will cost me a fortune to do that.

I don't think the problem is the battery, it's more likely some short circuit with the charging port, yes.
There are some replacement part stores for hov, I just found a charging connector: http://www.parts4repair.com/htc-one-v-dock-port-charging-connector/
When you look at the pics of the connector it seems to be soldered onto the mainboard, but it shouldn't be that difficult...
But,the phone charges with the original connector,I think it's battery problem,Is there any alternate way to keep it charged? I'm gonna check it but I am unable to open one phillip screw as it's threads are damaged.How am I going to open the damaged screw?Please anyone help...

If you already opened your phone, use hair dryer and lightly dry up your phone. Do the process for 3-4 times for about 2 minutes each.
You can check your battery with a multimeter, just follow below steps:
1.Switch off your cell phone and carefully remove the battery.
2.Now search on the label of the battery for its given voltage. Most batteries of cell phones are 3.7V
3.Place the battery such that its terminals face you.
4.Now keep the multimeter (either analog or digital) on DC Volt setting.It may be indicated with either DCV or just V and a straight line with 3 dots below it. In DCV (DC Voltage) also, there will be many settings like 2mV, 2V, 20V, 200V, 1000V. Keep the setting on the number above the actual voltage of the battery. It will be either 10V or 20V in most multimeters. An indication of ACV or just V followed by a curved line means AC voltage. Do not use this setting as batteries run on DC voltage.
5.Now touch the tip of the red probe of the multimeter on the terminal of the battery named ‘+’(positive) and touch the tip of the black probe on the terminal named ‘-‘(negative).
6.Keep both the probes touched until you see a stable reading on the screen of the meter. If the reading on the screen is more than 3.70 for a battery of 3.7V, then the battery is fully charged. And if it is less, then you will have to charge it with a charger. It should show a reading above the charge of the battery. If the battery is drained and showing 0 voltage or say less than 3.7, you will have to charge. If after charging for a long time, still it is showing the same charge, then the battery is faulty. You will need to buy a new one as batteries are not repairable. If the reading of the battery is below 3.7V even after charging it, your mobile phone will not switch on.

Thanks for the details buddy,actually when the phone is switched OFF and plugged to charger it charges and the LED indicator glows to green means fully charged and as soon as the phone is switched ON with the charger connected to it it charges again & again .Meanwhile the phone switches ON only when charger plugged on to the socket,It doesn't wake up on Normal battery condition.I am really frustrated with Non-removable battery type of this mobile.
Well,Thanks everyone for replying.The problem is solved after changing the battery.Big relief cause service center told me it will cost too much in changing the battery or changing the motherboard and I repaired it with very low cost watching youtube videos and a big help with XDA forum.
My Galaxy Tab S SM-T705 was working fantastic, untill one day, the battery dropped to zero. Then it got stuck. Wouldn't charge. Wouldn't turn on. I tried multiple things charging overnight with the original charger. Then I tried charging overnight with a heavier charger (note 4 power charger). That was until I read a guide on tech republic about how I needed to do a battery pull to negate minor trickle charge from the battery. Anyhow, I ripped the back cover off and took it off, and voila it started working.
However, I began experiencing crazy battery drain. I suspected that something was wrong with the battery; that I had damaged it with the overnight charging and stuff.
To remedy this, I ordered two spare batteries off of AliExpress. Hoping that I'd get this fixed by replacing the battery. This was until something happened that made me suspect that the problem is not with the battery
Today; I powered it off to replace the sim. And let it turned off for 6 hours or so. And while completely turned off, it drained 50-60% battery. This means that there are two possibilities.
Either the battery is ****ed and is draining battery ( i can test this by charging it up fully and then disconnecting it from the motherboard and then connecting it again after a day - if its drained while not being connected to the motherboard, then its the battery that's at fault)
If however, the battery only displays drain while being connected to the Tablet/Motherboard, then there's something wrong with the tablet (and its likely in this case that I can't do anything to fix this.
In scenario two, though, I was wondering, is it possible that it has something to do with the connectors on the back cover? There are these antenna that you can see in this picture: http://dl-1.va.us.xda-developers.co....jpg?key=YuQ4sx_xJyTckKe2XxlcWQ&ts=1436984729
I suspect that the power drain may have something to do with the antenna's on the back cover. Anyone know what those antennas are for? They say stuff like LTE and WiFi however, I've taken off the back cover and its still connecting to mobile data and wifi etc. So these may be extra antenna's etc.
network, wifi and bluetooth and gps need access to an antenna, have you tried turning on airplane mode to see how much power your tablet uses then.
Install GSam Battery Monitor, It calculate your battery drain in mah, also it will show if your tablet is going into deep sleep, and it can list the apps that use the most power in the App sucker.

The app below will allow you to see how many percentage points your tablet uses, for example overnight.

John.
The circled chip keeps on heating, even when I turn it off. I suspect this might have something to do with my battery draining... can anyone help?
I disconnected the battery from the motherboard, and it didnt draining. But draining when connected.
Imgur.com/3NLqmh5
Im Having exactly the same problem, and I say its not software, its the hardware! suspect in the power IC that manages the energy for tablet is problematic, check if your tablet while idle/turned off is heating on the bottom back. This excessive heating is the response of a malfunctional component.
I think the only way to solve this is sending to samsung specialized support to change the defective IC.
POst if your problem solves, I didn't solved mine yet.
Hello!
So I had my Samsung Galaxy Note 10+ taken in to the device repair shop in my town because of the battery not lasting long at all. They did testing and said that the wireless charging coil FPC had cold solder joints. I'm not sure what that means exactly but I had replaced the wireless charging coil and the phone is still dying at random times and at random phone percentage life.
I attached a copy of what the device repair shop had said about the issue with my phone.

Was it ever exposed to water? Any drops without a good case protecting it?
Does wired charging work?
Otherwise possible battery failure. Probably should've had the battery replaced when it was apart.
Loose or damaged ribbon cable or connector.
Worse case a mobo failure.

'Cold solder' is normally a reference to broken, cracked or just over all a bad solder joint. This would cause a bad, week (high resistance, low voltage) or no connection of the circuit.
If the battery was not charging properly, as blackhawk mentioned, the batter could now be bad.
Was the repair shop able to test the battery?
I am not a Sammy guy but, from what I understand they are a bit heavy on battery monitoring.
Maybe just give it a few charging cycles to see if the battery life improves.
Out of curiosity, what battery percentage is shown when the device turns off?
Cheers.

It may be the battery, I'm not sure. The guy at the device shop said it doesn't charge normal and had a .6 amp draw when he hooked it up to his deal. And no, no water damage or any other damage.
And my phone dies at random phone percentages. It could die at 85%, 70%, 50% I mean any percentage, and I don't even know when it's going to die when it does! But then when I put it on the charger, after about 5 minutes it'll already be at 50% charged.
I just want to be able to fix this myself instead of sending it in and paying an outrageous amount haha
I appreciate ya'lls help!

Replace the battery, especially if it's over 2 yo.
Start there.
Let's stay on topic, folks. If you have questions about how XDA works or how to enable/disable certain features, ask them in the About XDA-Developers section.
Thanks
