I have a Dell venue 8 3830, and it's been three weeks since it started to behave strangely. I purchased it more than two years ago, and it was completely fine before. Now it randomly shuts down at any percentage battery, and when I try to turn it on the battery is at 0%. Even after replacing the battery with a new one, the issue still occurs. There is no specific percentage when it shuts down, it can be anything like 20, 30, 50, 70. Anyone has the same problem?
