Early 2011 13' MacBook Pro Battery issues

[grum1978]

Hi,
I’m currently running a MBP 13’ 2.3GHZ i5 & recently Ive noticed a significant
drop in the battery life. I get around 4hrs based on standard use: Web browsing, emailing, Youtube & a bit of ITunes. I used to get around 5/6hrs.
I’ve checked the battery using IStat Pro: Battery health 97% Cycles 121.
The other day I had 88% of charge soon as I opened Youtube it dropped to 21% and stayed there even when I closed Youtube.
Is anyone else seeing this kind of thing???

Cheers

Grum

Completely normal. Battery life is based on usage.
