Help! My iPhone battery is draining too quickly!


I have an iPhone 4S that was completely replaced 1 1/2 years ago, so it's an older model, but still a fairly new phone. Apple gave me a brand new one because the top on/off button wasn't working and they don't have a fix for that (or at least they didn't at the time), so I got a new one for free.
I have been noticing that in the cooler temperatures of my work (grocery store), it is draining much quicker than it should be without being used.
I'm talking it was at 100% at 8:30am and by 6pm when I'm finished, it's at around 30-40% with minimal usage. It's in my locker all day, except for my 1/2 hour lunch break, and even then I'm only replying to texts or on Facebook. Not watching videos or Instagramming or anything. 
On Friday night it actually turned off at 39% just from being cold. It doesn't do this at home, and it's not even THAT cold in the store, usually between 60 and 70 degrees. 
Has anyone else ever experienced this accelerated battery loss from cold temperatures? I  don't have this problem when I'm at home. Maybe I just have a weird phone? Lol

Battery Problem

Hello there!

I have an iPhone 5 and I have also experience accelerated battery loss from cold temperatures, although only from temperatures much colder. During the winter if I take my phone out to text while I am outside it will usually die within 10 minutes. The temperature would be around 5 degrees or lower so I was never really upset about it because I am hardly functional in those temperatures. Maybe try keeping it in a sock or something warm while it is in your locker, if that doesn't work maybe call Apple and ask.

Battery Problem

Oh, yes, mine does that, too. Doesn't last more than a few minutes outside in minus 20 or 30 Canadian winters. I keep my phone in my purse and usually it's ok during the warmer parts of the year like now. Yesterday was an oddly chilly day, so I'm hoping that's all it was. Today it didn't die in my locker, but still, lost almost 70% of batter power during the day.
I'm thinking it might be getting close to time for an upgrade, even though the condition of the phone otherwise is very good.

Battery Problem

That is still a lot of battery power. I find mine loses a lot when I'm in the car travelling long distances, probably because its always searching for a signal. Turning it off might help too. The new iPhones battery lasts much longer so maybe that is a good option.

Airplane mode or just generally lower its activity?

My iphone 5 also is terrible at sustaining battery power. However, the power that it displays in the cold is not always accurate (I find). I have had my phone jump from 30% to dead, then when it gets warm, I am able to turn it back on and it is still around 30%. Sometimes ill put it against my skin (in a sleeve or something) and this will warm it up and let it work a little longer.

If you're just storing your phone all day without checking it, why not switch it to minimal lightness, close all the aps, maybe even turn off cellular data (under "cellular" in settings to only use wifi), or even airplane mode? I have coworkers who bring their chargers to work because their phones just don't last.
