I have had my iPhone 5s for almost two years now, and the battery has been dying quickly. For example, even when my phone is on airplane mode, it will drop from 90% charged to 85% charged within two hours. I'm pretty sure this is due to the battery life.

Is there an easy fix that will not cost me more than replacing the phone?

    A 5% drop in 2 hours is about 40 hours of battery life. How does it do when not in airplane mode? – William T Froggard Jun 9 '15 at 2:16

    A 2year old battery is not old. You have something eating it up. – Ruskes Jun 9 '15 at 2:31

Battery Drop of 5% in two hours is not bad

A battery drop of 5% within two hours is not bad at all. How much does it drop throughout an entire day? How long can you use it for taking a few calls, browse a little? If it only drops heavily, when not in airplane mode, please check your battery usage: Settings -> General -> Usage -> Battery Usage


Apple offers an about $80 (+ $7 shipping) battery replacement-program for iPhones https://www.apple.com/batteries/service-and-recycling/

Alternatively, if you - or a friend of you - like to fix things yourself you could consider a iFixit iPhone 5s Battery replacement kit, which is about $30 (without shipping) https://www.ifixit.com/Store/iPhone/iPhone-5s-ReplacementBattery/IF124-002-2

iFixit provides very useful guides of how to fix electronic devices from Apple or other manufacturers.

Check warranty

You might want to also check your warranty status: https://selfsolve.apple.com/agreementWarrantyDynamic.do

If you have an AppleCare Protection Plan they might replace the battery for free!

    Thanks - info on replacement options is very helpful. I've definitely noticed that the battery has been deteriorating over time, and it's worse when I am texting back-and-forth and/or using location services. Sometimes, when I do this, it will drop 30% in an hour. – Elaine Jun 11 '15 at 1:38

    Wow. 30% in an hour is pretty bad. Did the battery usage screen help at all? I hope the information above will help you solve the problem :) – skofgar Jun 11 '15 at 18:46

    I just noticed, I forgot to mention, that you should verify if you still have warranty! They might replace the battery for free then! – skofgar Jun 11 '15 at 18:49
  • Good point! Will look into that. – Elaine Jun 12 '15 at 22:23
