Had a Dell laptop for just over 10 months, noticed that the battery is now lasting less than 2 hours as opposed to the 4 it was lasting when I bought it. Laptop is used for uni, so does spend a considerable amount of time on battery power. I appreciate a laptop battery only has so many cycles, but I checked my daughters 2 year old Toshiba (which is used out and about a lot) and windows states that it's still holding 100% charge.
Spoke to Dell cs who had me run a couple of tests, update the bios then say that it's a consumable and tough, but surely it should last more than 10 month?
