IPhone 4S BATTERY DRAINS TOO QUICKLY! Read description and

I have the iPhone 4S on Verizon. I got the phone on October 17, 2011, which means I could upgrade to the iPhone 5 now, but when I go to buy a new iPhone, I want it to be the newest of the newest so I think I'll wait for the next iPhone to be released.

Anyways, to the point. Since the phone is hitting two years old, of course the battery life is going to be effected. I could always get at least to the end of the day with my phone, until recently. About two months ago I started having to charge the phone 2x a day and now I have to charge it 3x on normal usage and sometimes 4x on really heavy usage days. What should I do about this? I don't always have a phone charger, I need my phone at all times, and I don't see my self paying $80 to replace the battery on a phone that I'll only be using for another month. Is there a cheap way out of replacing the battery? And please don't recommend taking the phone apart!

Download "Battery Doctor" it will help for another month. It's free and also helps with cleaning memory.

Buy a portable charger or power bank… They can cost as low as 20 dollars… Will help

Just hang on! It's only one more month.
