Fixed my 4s battery munching problem

[freeradical]

I had a new battery installed in my 4s recently, and all was good. The phone could run for a few days on a charge if I wasn't using it.

iOS 8 BTW

Then all of a sudden, it started eating the battery alive. The percent charge could literally go down 10% in an hour. The back of the phone also felt slightly warm even when I wasn't using it.

So last night, I shutdown pretty much all of my apps, and put the thing on the charger. I took it off the charger around 7 am, and it still says 100% charged. Yay!

So much for apps that don't play well by properly suspending themselves.

I suspect one of my apps that use GPS was responsible for this.

I'm not sure if I'm clever enough to comment reliably on this, but when I noticed rapid battery drain, my phone said a lot of it was due to GasBuddy, which puts your location on a map along with prices at local gas stations.

Quit GasBuddy, and things seemed to get better.

I'll also vouch that location-identifying apps - Spothero, Maps from Apple or Google, et cetera, all will chew excessive battery seemingly polling location of GPS and communicating that even when you don't have them active (i.e. "open, but not your front screen nor recently accessed.")

I had that happen one, the phone really felt warm. Quite all apps and reboot and all was fine. Same thing happened to a colleague, same solution fix his problem.

A run away process or some other weird software thing.

Check your Privacy > Location Services settings. Many apps track you even when not in use. Under iOS 11 you can override this behavior to have it use your GPS only when the app is running and with any recent version of the iOS you can entirely disable access to the GPS for any app.
