Q: Late 2011 13" MacBook Pro Battery Capacity

I've noticed the battery on my late 2011 13"  MacBook Pro doesn't seem to hold charge for long, I can take the machine off power and it will die within around 90 mins of light usage from 100% down to less than 10%

 

I've tried a full discharge and recharge cycle and checked the cycle count in System Details (screenshot below):

Any ideas why the battery is losing capacity so quickly? I'm not running any power hungry apps and it even drains quite quickly when sleeping disconnected from power.

MacBook Pro, OS X El Capitan (10.11.5), 13" Late 2011

Hi,

 

It's certainly nowhere near the maximum cycles count >  https://support.apple.com/en-us/HT201585

 

Check the adapter > Apple Portables: Troubleshooting MagSafe adapters



"it even drains quite quickly when sleeping disconnected from power."


Just in case quit all open Applications prior to putting the Mac to sleep to see if that makes a difference.
