A friend of mine just forwarded me an article on iPhone 4S battery life problems.
From the article:
Some chalk it up to the more power hungry dual-core processor, which makes sense. Kind of.
Some problems brought up were:
- Corrupt iCloud contacts
- Apps bugging out, not closing properly
- Location services (remember, if you have Find my Friends turned on, GPS is always on, location reminders too!)
- iTunes wi-fi sync. Technically this should only happen when the phone is plugged in, but it could suck more battery
- Sending Apple some error reports.
In addition to these, keep in mind you have a new iOS 5 too. Some battery sucking features area:
- Mail notifications! If you’re like me, you get hundreds of emails a day. Each one turns your phone on to display your emails (if you turned this on)
- Find my Friends, when turned on, constantly uses both GPS and data services
- Those video calls over 3G, they suck battery life
- Siri! It requires high computing power, and bandwidth when you use it. The more you talk to your phone, the short it’s battery life will be.
What can you do? Turn it off!
I believe 70% of the people out there with everything turned on don’t use it.
Take a little time and go through your options and settings. If you don’t use something, turn it off.
I’m constantly turning WiFi and data off when my batteries are low. I can last for days on 25% battery if I turn off all services except phone calls.
