Few things are as frustrating as realizing your phone is about to die.
If you run into this problem often and don't want to go through the trouble of keeping an external battery pack and cable on you all the time, it's smart to invest in a battery case.
Mophie was one of the first companies to make battery cases, and its wirelss Juice Pack helped my iPhone stay alive for over 30 hours.
Right now you can save up to $26 on the Juice Pack by picking up either the iPhone 7 or 7 Plus version as an Amazon warehouse deal. Although the case adds some bulk and weight, it's not enough to outweigh the benefits of adding multiple hours of life to your phone.
The case can be charged using a regular micro USB cable or one of mophie's wireless charging pads, which are sold separately. Both methods will charge your phone and the case, and the wireless option is particularly useful if you like charging your phone on a nightstand before bed.
You can read my full review for more comprehensive information about the case, but overall it's one of the more practical iPhone accessories I've ever tested. If you know you've got a long day (or trip) ahead of you, it's easy to slip it on and definitively end your battery anxiety.
On days when you know you won't use your phone as much, you can also take it off and use a slim case instead. Although, I will say, as someone who has been off-put by battery cases in the past because of their bulk, mophie's case was never a chore to use.
The current warehouse deal makes these cases cheaper than their typical sale prices, so if you want a way to stop constantly monitoring your phone's battery and using "low power mode," you should take advantage of it.
