Huawei s7-301u - not charging - Huawei MediaPad, T-Mobile SpringBoard

Hi,
I've tried few different chargers with no effect. So I have decided to open back panel and I've noticed that when I attempt to charge device battery stays completely cold but area right under sim card slot getting really hot.
Is that mean battery need to be replaced or is it something else.
Thanks for any help.

Try unplugging the battery and plugging it in. If it gets hot still, it is likely a short. If it doesn't, it is likely the battery.

2.1 roms have a battery leak, and android has a bug with the battery when booting while charging. turn off gps, turn off your phone, wait till it is fully charged, then unplug the charger and turn it on again. then check if it is still that bad. also flashing other radio versions might help, the 08.29 radio is said to work better with the 2.1 kernel.

How to know if the battery is about to die

Hi
When I switch off the cell and the battery symbol is shown, it is shown with a yellow triangle and a thermometer. Does that mean that my battery is about to die?
Thanks,

Also, this is when the charger is not plugged in. And there is no clean way for me to restart my phone. I have to plug in the charger and then only I can switch on the phone.
I am on 2.3.5 and this was fine till a couple of days back, and now the phone has become a big mess. Tried reflashing, but with no success
Will appreciate any help.
Thanks,
Vishal
Very odd, does your phone feel hot?
No, not at all.
Thanks,

I've Had that a couple of times when I put my phone down a little on the non gentle side!!!! For me it was a slightly loose fitting battery (the anker 1950) which i sorted with some tape.
My battery stats always showed an odd drop of about 10% whenever this happed.
So normal (ish)!!!
i think its pretty common but most people dont notice it since its only really visible when the phone only been on for a few minutes. then the diagram will show a longer time and therefore the gap will be smaller or close.
