What should I do to solve battery drain issues on my iPhone 6?

Should I calibrate my iPhone 6 battery or reboot to solve issues with battery drain?

Added (1). Certain apps like Snapchat really drain my battery and if my settings say that Snapchat takes 62% of my battery usage in background activity, does that I mean I should delete the app?

Phones deteriorate over time. Batteries are lithium ions, that has a specific no.Of cycles.
Do not overcharge your phone. And charge only when you have 20% battery.

Turn off auto-updates to the apps you don't need automatically updated. If you can't shut off background use by Snapechat, delete it. Opera Max has the ability to shut down apps, running in the background.

I found something online before which helps my phone battery. It may sound odd but it works. Once get your phone charged up.1. Hold the Power but on your phone in until Power Off, Power Off & Restart and Turn Airplane Mode On pops up, 2. Then tap on Turn Airplane Mode On and once on repeat steps 1 and 2 except this time tap too Turn Airplane Mode Off--This will help save your battery big time. Tho everytime your recharge or turn phone off n back on you have to repeat the steps again. Also keep brightness down to around 30 percent

May involve having to get a new battery altogether, but no harm in at least trying those methods.

  • Should I completely drain my iPhone 5c's battery before first charge? I've just got my brand new iPhone 5c today and it came with about 90% battery when I first turned it on. I'm now on it and it has 55% charge. I'm wondering wether I should drain the battery to 0% then fully recharge it to 100%, that's what used to be recommended but I'm not sure if you still have to do it. Will you please let me know what I should do. I will get to sleep in around 2 hours, FYI.
