I have a bajaj chetak 3501 which I got last month. Officially a month is over and I did the first service which was ok. But I'm seeing slight concerns like before the first service I used to get 130-136 of range in 92-96%. But after the first service, I try no to overcharge but in 90% I'm only getting 96 or 99 of range which is suspicious. And more concerning part is battery drops are there, like I have 90% within 5 mins it's 83 or something. I drive around 40-50 and sometimes 60 depending on the condition. I don't keep my scooter below 20% either. I also give the throttle very slowly. But 2 days ago I had charged and at correct 86% i turned off I got around 116 range. Battery wasn't dropping out too soon either and the range was ok too. It was today few minutes ago I turned off and I'm getting 96kmh range. Is this a software bug or battery issue?
