how do I fix my iphone 6 the battery life

[iMore Question]

The phone can say 6% all day but if I turn it off and back on it will change to 3% and now the screen is messing up by popping up red lines than turning itself off...the phone just wont die it just keeps itself on at 3%. What do I do?

Hi, welcome to iMore.

It's best to make an appointment at the nearest Apple Store to have your battery checked.
Looks to me like your battery charging cycle has reached its limits.

If there is no Apple Store in the vicinity, try your retailer.

Looks like you need a battery replacement. Just Like Tartarus has mentioned,visit the nearest Apple store or any authorised retailer.

Yep, sounds like the battery is getting worn out.
