Hello, guys. I own an iPhone 5 since 2012. Lovely phone with great battery life when I bought it (iOS 6). With iOS 7 the decline started. Today battery life's a nightmare. If I go out with 100% at 8 am, I will be out of juice in 5-6 hours (1-2 pm) with my usage. I thought it could be a software problem, so I DFU recovered the software. It did not work. I thought it could be the hardware, so I got a replacement by Apple. Battery life improved by 20-30%, but nothing more and still not acceptable. Is iPhone 5 just dead and condemned to ridiculous battery life with iOS 8? Is iOS 7 a watershed since it was completely rewritten (that's why iPhone 5s doesn't have this problem)? Am I forced to change phone? Thanks a lot. PS. my settings are: - 3G and 4G on - Wi-Fi on only at home - Bluethooth off - Automatic brightness (pretty low, for example when it's dark it's on minimum) - a few push notifications (only important apps) - just 4-5 apps in background refresh (like whatsapp and telegram. Turning this feature off does not improve anything) - localization only for a few apps. Every system service is off. - push on mail is off Running iOS 8.1.3. Thanks a lot My usage is not that heavy. A bit of messages and mail, and a bit of Facebook and Twitter on the go. When I bought the phone I could get one day of battery life with pretty much the same usage.
