iphone 4s battery problem

Depp

been using an iphone 4s the last while, just replaced the battery before christmas and its been performing perfect since, about a week ago the battery indicator got stuck on 1% and while the phone could be fully charged i.e. allowing for a full days use without dying it just stayed on 1%. Couldnt find a fix for this so just left it at it and continued to use, died yesterday and has been plugged in since and wont turn on. fairly sure the problem is the battery has charged but as the indicator hasnt changed the phone wont let itself turn on as it doesnt think it has reached the necesery 4-5% it usually needs to turn on. Just thought I'd ask on here to see if anyone knew of a way around this before I head for a shop or something like that to get it looked at, many thanks!

Have you taken a look at the battery? I would open it up and take the battery connector off for a few mins then put it all back together and try it again. If that doesnt work just get another new battery
