Help battery dies down instantly even when 15% remaining

[umair4]

Dear All,

I bought my xperia arc s 6 weeks agao and recently have encoutered the problem that when my phones batrery is discharging, and when the first notification of low battery appears, the phone shuts down and the battery light starts to blink. What might be the reason? i have faced this issue thrice.
Any help in this regard will be appreciated.

Kind regards,
umair

I think 15% is probably normal,

That doesn't sound normal to me. I can go all the way down to 3-4% on my EVO before itll shut itself off.

That may be because of the different manufacturers though.

Personally, I'd call Sony

Sounds like calibration. Quite common on my model (HTC Desire). Ironically with my phone shutting down followed by a charge usually improves the calibration somewhat

Doesn't affect battery life, just that the meter is misleading. And at least on the Desire 15% is about where it often drifts to.

I have the same problem but the thing is I am pretty positive that I did not have that problem before installing CM7 on my desire gsm.

i have the same problem with my arc s too.
battery notification also toggles haphazardly..from 79,78,77,76 it'll go back to 79 and come down again.
At the end wen battery is around 10-15% it'll suddenly sho low battery and shut down.
