Defective '5,000,000mAh' power bank
It arrived dead, but in a highly dangerous state and could have burst into flames at any moment.
There are countless iPhone battery saving tips floating about on the internet, but which ones actually make an appreciable difference, and which aren't worth the effort? I've done the real world testing to sort the wheat from the chaff.
It's easy to compile a list of iPhone power-saving tips, but I'll tell you now that putting them to the test to find out which work and which don't is tedious and time-consuming work. But after several weeks of real-world testing I've found what I believe to be the best iPhone battery saving tips, along with a handful that are just not worth bothering with.
For these tests I used three different iPhones - an iPhone 5s, iPhone 6 Plus, and the new iPhone 6s - and all three were running the latest iOS 9.2.1 update. All the handsets are fully functional and battery life appeared to be normal.
Each iPhone was configured in a similar -- albeit not identical -- fashion. I then applied one of the many battery saving tweaks, then they were used normally throughout the day (email, iMessage, Facebook, Twitter, web browsing, some calls and such) for several weeks while measuring battery consumption at fixed intervals.
What I was looking for wasn't how long I could get out of the battery, instead I wanted to find out which tips extended the battery life the most. And spoilers; many of the battery saving tips that I tried seem to have a negligible effect on battery life.
Note: My listing is based on real world testing. However, I'm fully aware that your real world might be different to mine, and that as such your mileage may vary. For example, if you do a lot of gaming on your handset, or use the camera a lot, then this will have a dramatic impact on battery consumption, and the tips below might not help you as much as they'll help someone who uses their iPhone for email, Facebook, Twitter and web browsing.
