battery problem....wont charge if 0%

ok, on my xda mini s, if i plug the charger in at 2% to 99% it charges fine
but, i let the battery go so dead that it wont charge. so i bought another one and it did the same
is there a software fix for this? can i charge the batteries another way? both are only 6 weeks old and charge fine in my mates mini s (one of the first ones) mine is only 6 weeks old
its now getting very annoying
thanks

What are you running? G3 or G4, IPL/SPL, ROM version??

hi mate
ipl 2.21.001
spl 2.21.001
gsm 0.2.07.10
os 2.21.4.1
so just to clarify, I think there needs to be a tiny amount of power the the device to power it enough to recognise the charger is plugged in
i have 2 batteries with 0% energy - none will charge. The 3rd battery charges fine if more then 1% is left before I stick the charger in
thanks

Actually my boss had the same problem with his 8125. He was running wi-fi & music and it killed the battery all the way dead. I don't think there's a fix. He had to buy a new battery.

Looks like mfrazzz has the answer!

wow, ok i am a nuby and you might not like the solution but, every time my battery runs out completely and i cant charge it, disconnect the charger trust me on this one, lick the top of the charger connect it back and at first it will show a red light leave it there for about 4 minutes, then disconnect it and connect it back and your battery will start chargin again. trust me on this one ive done it like 4 times.

Dude!! I just have to ask...
HOW DID YOU FIGURE THAT OUT??? I mean, where you just sitting around thinking... Hmmm... I think I'll lick the top and stick it in.. hummm... I guess I'll leave it in for about 2 min... no... 3 min... oooo I think 4 min would be perfect.. then I'll unplug it and ummm... plug it back in!! Oh yeah!! That will do it!!!
Just kidding around!!!

wow, amazing stuff thanks
can i get an external charger/docker for the batteries?
do ALL these devices have the same problem or just the newer ones? my old one didnt do it (unless it still had some power in it)
Thanks

There is both a battery charger that you stick your battery in and a cradle that charges both your Wizard and also has a slot for a second battery. I couldn't find the single battery charger, but the dock can be found by searching for 8125 twin cradle.

Ok, on my 8125 with the battery oriented exactly how it sits in the phone, the + is the top most contact and the - is the bottom most contact.

Here's a pic of a battery I found and you can just make out the + (red) / - (black) on the pic.

[Q] Battery meter issue since 4.2.2 (stock, no root)

My N7 has turned off twice (seemingly at random, without any warning) since the last update, each time when there was about 20-30% battery remaining according to the device settings. It had never done this before. each time I tried to turn it back on and was unable to, saw a message about battery being too low to turn on and connect to charger. So when it most recently happened last night, I left it plugged in all night (7 hours) on the included charger and when I woke and turned it on it still only showed about 65% charged. Did a master reset, took the device to work, connected it there to a different micro USB charger (HTC branded) and got it up to 100%. now is been nearly four hours later, only light use in that time, but the battery remains at 100%, says "Charged" in the notification tray, in "Not charging" in the battery settings. So I guess my question is (and I have looked around and didnt see an answer) can I fix this without rooting?

Rooting won't enable you to do anything special to fix this. If you've already tried a factory reset with no joy (or even if you haven't yet), remove the back cover and verify the battery connector is firmly seated- even go so far as to unplug and replug it.
Also, you may want to do a quick search of the forum, as this isn't an uncommon problem.

I did do the factory reset as soon as I realized the problem and nothing has changed since then. It's now been on battery for over 21 hours and says it's at 70% which can't possibly be correct. What exactly does the battery connector have to do with the meter being inaccurate?

Charge level is reported by the battery's fuel gauge. A poorly seated connector is a very common cause of this issue.

well, i just opened her up (while device was powered off), unplugged the battery connector, reconnected it firmly, and powered back up. nothing has changed as far as I can tell, so what do I do now?

Then I guess you need to RMA it.

Battery issues

Hi everyone. My Nexus 7 (WiFi 16GB) is almost unusable ever since the latest update. The tablet does not charge properly, it is very slow, and once it reaches 67% it stops and doesn't go up anymore. And it drains very quickly as well, it takes just under 4 hours from 67% to something like 10%. And even when I plug it in, I need to leave it alone if I wish it to charge, since it still does not charge (it does, but the discharge rate is bigger than rate charge, so it basically is discharging while charging). I tried flashing another ROM but I get Status 7 in TWRP, I have been getting it for a long time now every time I try to flash an update or a ROM, even though I flashed factory image on it, both manually and via some toolkit. I cannot do it now since I am not home for another week or so, and the only computer available to me is not mine.
Is there anything I can do at this point? I do not even know what is it - is it 4.2.2 or the battery itself (I tried turning it off and charging it while it is off, the same thing happens - very slow). Also, I should add that I am mainly using the original charger which came in the box, but I tried other chargers as well. It was bought from Play Store in November 2012, so I am the first owner.
Thanks

I'm in the same boat, although mine is unrooted and stock... I can't recall if this started since the last update, but it was a gradual slope down to where I haven't been able to get it to charge for the past day. at first it was just charging really slow, now it's not charging at all. I'm using the OEM charger and cord (tried another usb cord, but still nothing). When I plug it in, the charging indicator will come on, however it just doesn't charge.
I've tried all the fixes in the stickied post (plug into computer, then wall... quickly unplug and plug the usb into the charger repeatedly, turn off and charge... pop the back off and unplug and replug in the battery), but I think my (our?) issue is separate from what that thread is trying to solve.
One thing I tried is turning it off and plugging it in. the larger battery icon would show up, show that it's charging, but letting it go overnight like this, then turning it on, it's still at the same % as when I turned it off. Nothing is working.
I'm beginning to believe that my nexus 7 is on it's last discharge unless anyone has any suggestions. Below is a screen shot of my battery discharging even while plugged in. the short spike was after rebooting then unplugging and replugging it back in... but then some unknown time later it just stopped charging. the small spikes at the right are trying all the methods from the sticky thread trying to get it to start charging. I then turned it off overnight with it plugged in.. and it's the same.

Samsung galaxy s4 dead

Just got a new battery because the old one died. Had the phone for around 4-5 months now after upgrading from the s3 that did the exact same thing. The phone is stock no custom Roms or root. It just dies, turns off. When turning the phone on it makes it to the galaxy logo and then powers off. I cannot make it to recovery mode and charging it does nothing. Plugging it in with no battery does not power the phone on either. Please help me figure this out.

Get your charging port checked. Maybe the way you put phones in your pocket or somewhere makes it go bad.
Things like this happen once, not twice brother.
Clean your charger and your charging port. Try connecting to a pc and see if it starts charging.
Or maybe your charger went bad.
Do press thanks if my posts are helpful

I can't get into recovery or download. When the splash screen comes up the phone turns back off... If it even makes it that far. This happened with the s3 as well and i looked it up on google as being "sudden death syndrome". The charger and port are fine, the phone is brand new.
Hold power
1-2 seconds goes by
See Samsung Galaxy screen
phone turns off
When its being charged it says 100% complete and then when i took out the charger it would instantly drop to 90%. After that if i sent a text or any message it would drop another 1% and this was the same deal with the s3 that died and would never turn back on. The phone is literally brand new and i just replaced the battery less than a week ago with a new one. The battery is just not holding charge but its brand new but the same thing happens plugged into USB with the charge cord and no battery

Exactly the same problem here. Last week on Android 6 it would take about 2 1/2 hours to charge the phone from empty to full. Now it takes over 4 hours to get from 40% to full. Don't factory reset, I've tried it, doesn't help. I've also tried charging with the phone off, slow as well.
HIGHLY ANNOYING. If anyone has any tips, please let me know. Maybe worth noting: it signals "cable charging" when plugged in. I think it said fast charging detected on Android 6, but I'm not sure.
Of course I've checked if fast charging is enabled in system settings

My first notice about android 7 it was slower in charging but I thought it was better to preserve the battery.
The other notice I have noted, that the first time I plug the charger it will be normal charging, I remove and plug it again it will be fast charging.
So if you get very slow charging please read the notification if it is fast charging or not, if not remove the charger and plug it again. But it is still slower
