My battery popped open the case after about 3 years. I suppose the capacity had deteriorated, but I didn't notice because I kept it topped up all the time by having it on the charger.
But I guess that was the problem, because I learned that a lithium-ion battery won't last as long if you keep it fully charged all the time. I downloaded a free app that tells me when it's at 80%. I set it to notify me by voice when it gets to either 80% charge or 30% charge. I believe the battery will last longest if kept within that range. At least that's what I've been able to gather from researching the subject online.
