Battery going from 25% to 1%.

[AnshulJ]

Hi,

I have not being having a battery problem with my Arc since i bought it in Sep 2011. I keep it updated & everything. I updated it recently to the 4.xxx.62 update. Today, i was playing PINBALL Deluxe as usual when my battery level was close to 25%. Just two mins. in the game, I got the Low battery level popup showing the current level as 1% and the phone got turned off.

I was freaked out a litlle, but I whipped out the charger & started charging again. When the fone started, it showed the Battery level up to 26%

I unplugged the charger, & kept the phone as it is on standby (Brightness - 25%, Data - off, No apps running)

But again in 5 mins, the popup appeared indicating my battery level to 1%.

I am not sure why or how this is happening. The phone is still in warranty & the battery definitely hasn't gone bad. Please help me.

okh do this
take out the battery of your mobile when it goes completely down, means when it switches off itself and keep it out for about 1 minute
reinsert it , without switching on your mobile plug in the charger and charge it for about 5 hours untouched and then remove the charger and switch on your mobile, it might not show full 100%, so chage it to full and u will hopefully never face this problem again

remember to share the results here

Ohkk, will do that & keep it posted. Is this a known issue with the update?

if the above doesn't solve your problem then u might need to repair your software

it happened with my arc 4-5 days back , i also reported this issue..

i faced the same exact issue...

and nabeelraza's advice is the solution

first fully charge your phone to a 100% , then take out the battery , let it out for 5 minutes , insert it..

and you will see battery level at 85% , thats for sure , charge it again to 100% and it will not happen again

Is the SUS available in India??

Slim,

I tried your way. I took out the battery for 5 mins & upon restarting the level was 78%

Charging it up again to 100%. Do i need to keep it charging for 5-6 hours like Nabeel suggested or just till it reached 100%

[slimshaddy]

first you have to charge it to a 100% then take out the battery , and as nabeelraza mentioned , no need to charge it 5-6 hours , just upto 100%
