Stuck on 0% Battery

Heres the deal. Last nite my battery died. I stuck it on the charger for like an hour. Still showed 0%. Left it on the charger another 3 hours or so, still at 0%. Tried different battery and left it on the charger all night, 0%. Thats also trying 2 different chargers. The biggest problem with this is that I can't use the phone to call out even when its plugged in because when the battery thinks its that low, as you all know, the phone goes into airplane mode.
Any ideas on whats wrong and if not, any ideas how I can bypass the phone going into airplane mode automatically?
I am running the latest update.

[Q] New GENE... HTC P3400i

Hello everyone!
this time i've weird problem with my new gene HTC P3400i having windows 6 professional.... As my daily routine i put my phone on charging at night around 2AM and unplug the charger when i wake up around 7AM till then phone gets fully charged from 5% to 100% but one day when i woke up and unplug the charger it was only 22% i thought may be charger was unplugged so i put my phn again on charging and gone to do my work, after around 3hours when i saw the phn it was on again 22% but phn was showing charging i was curious like wat happened to phn, then switched off my cell and plugged in for charging but again after one hour when i switched it on it was on 22% :| i unplugged it and went out and saw that battery was draining very fast... 22% then 20% and so
on and withint 15min it was on 2%, i was out for around 5-6hours and my
phone was still alive with 1% charge remaining then atlast it died.. i tried to switch it on 5-6 times but it start goes to boot screen then windows logo and red service light and turns off....
end of phase 1
x-x-x-x-x-x-x-x-x-x-x-x-x
i reached home plugged phone for charging and after around 15min turned it on... now the problem begins.... when i turned it on it goes till windows logo with red light and switch off on its own... i again tried switching it on with charger still plugged but it doesnt respond i tried 10-15 times but of no use... i left it there for a while and again swithced it on again the whole process started till windows logo and red light and switch off... then again no response.... i thought may be battery died(well i dont think coz suddenly battery cant die on
its own when it was giving stamina for 1day for a 2year Old GENE).. so i went to buy new battery and switched it on and it worked like as usual but i noticed that battery was draining very fast in front of my eyes.. i plugged in for charging and it was charging fine when it was 100% i unplugged the charger and suddenly i saw that charging meter went to 89% :| :| i tried plugging it again and again unplugging but this time 77% :| i thought may be there is a problem with battery itself so replaced my batery with new one and again plugged it in phone and switched on this time i thought it is fine and plugged it in for charging but again the same problem when i unplugged charging meter went to 90% and subsequently battery drainage... :|
and yeah one more thing i noticed is when i plugged charger without battery the service light shows red light blinking very very fast however with normal phone it should be like call, end buttton and amber light shows up for one time and gone....
Can anybody help me out with this ... please help me this time :| :|
charging problem
hi buddy
this problem because of your charger either u r using a duplicate charger or another charger having different frequency..
all u have to do first bring the charge of your battery to zero and then use a original charger its temporary problem i have also met this thing 3 or 4 times ... don't panic it will be resolved...

[Q] When turning off, a fully charged battery has 0%

Finally receieved my Nexus 4 after almost 2 months waiting, but not really enjoying it right now.
Received it yesterday, unpacked it and I couldn't turn on the phone. So I've connected the cable into the charger and a light showed up.. After 30 min I saw a battery icon and after 1 hour I could turn up the phone.
When turned on, it showed 3% battery, so I let it charge for about 5 hours. While charging I've noticed something strange.. it was charging very slow. After 4h of charging it was showing just 16% battery and 1h later it was suddenly at 70%. After it got till 99% I unplugged the charger and tried to use the phone.
Everything worked till I wanted to restart it. The phone doesn't want to start up! Pressing the powerbutton for 20-30 seconds.. nothing happens. Tried the volume button combination.. nothing. Plugged it into my PC and after 10 min the battery icon showed up?! The battery was at 0%! The battery went from 99% to 0% just by turning it off!
I've let the phone charge again, this time the whole night (7 hours).. It was fully charged at 100%. I disconnected the charger and turned off the phone.. and again: a black screen.
I've Googled and searched everywhere but couldn't find 1 thing.. what could be the problem of this? How can my phone go from 100% to 0% by turning it off?
I have no idea what is going on but you need to contact google asap, they'll send a replacement and hopefully the new one isn't a dud.
If you want to try playing with it, plug the phone into a different charger with a different cable, let it charge overnight/12hrs and give it another shot it could be a bad cable/charger (to be honest I think this is a long shot.)
Really sounds like a hardware problem.
Your only option is RMA.

[Q] Battery won't charge, new battery unrecognized

I've been having some issues with my Motorola Defy these past few days and I am hoping someone could shed some light on a potential cause for these issues.
I've been running cyanogenmod 7.2 for the past year and this is the first time I've had a problem.
Last week I noticed my battery draining incredibly fast, to the point where I would go from 100% to 0% in an hour or two. That time slowly dropped to where the battery wouldn't last more than a few minutes. After that I plugged it in and the battery would not charge past 4%.
I assumed my battery was bad so I ordered a new one. I got it in the mail, popped it in my phone, charged it to 100% and it managed to last about 4 hours before it dropped to 0%. I tried to charge it and once again the new battery would not go past 4%. I took out the new battery and tried the old one once again, but nothing changed. Once I put the new battery back into my phone, the phone will not longer recognize that the new battery is in. It shows the battery with a question mark whenever the new battery is in my phone.
An additional thing to mention is that if I plug the phone into my computer, I get a white light and the phone never boots.
That's where I'm at right now. My old battery will not charge and sometimes when I put my new battery in my phone it is unrecognized.
Any help would be great, thanks.

Try updating CM 7.2 again in custom recovery with full wipe(data/cache/dalvik), and this worked for me battery started charging.

Screen flickered, battery died

Hello everyone,
I read about this problem elsewhere but it didn't help.
Today I was at 40% of battery, phone ringed, I rejected the call, after few minutes picked it up, unlocked, screen started flickering and it died.
It didn't want to turn on. Took the battery out then back in, still didn't power on.
Placed it on charger, it started to charge, showing totally empty. After few minutes it went to 20%.
Took it of the charger, took the battery out to inspect it after reading on internet, it looked fine. Put it back in, turned it on, I was BACK AT 40%!!
Phone is one month old, practically new phone, never dropped it, bent it, nothing.
first of all fully drain the battery to 0% and then change battery to 100% and calibrate it thought this app https://play.google.com/store/apps/details?id=com.vitula.batterycalibration&hl=en if it is still showing the same problem then it is possible that the battery must be faulty.
Yes it sounds like a faulty battery but its a new phone so I rulled that out
I usually charge the battery only when its less than 10%, usually 3-5% and then top it up to 100%. I never partially charge it. I will try this app next time I drain it
