No. We have a couple hundred phones at work that are 5-9 years old. Does failure rate increase with time? Of course. Until you hit 5 years, the phone is perfect

- bigiain 1y agoI think it's charge/discharge cycles more than time that gets to batteries. I've heard that a decent rule of thumb for LiPo batteries is that they'll drop to around 80% of "new capacity" in around 1000 cycles. So around 3 years to drop to 80% capacity if they're fully charged/discharged daily, or around 5 years if they're only discharged to 30-40% and topped up daily. If you only charge them once every week or month (like my Kindle), the battery will probably still be fine after 20 years. And on the other hand if you're the sort of person who talks on your ophoine for several hours a day (like my boss) or streams YouTube all day - and need to recharge your phone in the middle of the day, you'r battery could drop below 80% in a yeah and a half.
