I bought a Thinkpad E450 from Amazon last year. First day I plugged it in, the battery died. I had a battery replacement which after a month started failing, and more recently, another battery replacement.
After that I've been using the laptop for almost 3 months without any issue, but when I checked the battery status I got:
Battery 0: Discharging, 53%, 01:31:19 remaining
Battery 0: design capacity 4119 mAh, last full capacity 3841 mAh = 93%
A month ago the last full capacity was around 97%. I'm afraid to have another issue with the battery, and the warranty is about to expire.
Is the full capacity decrease to 93% normal for a 3-month old battery or should I should take the laptop in for service again?
