    Hi there, just simple question. I got new unopened iPhone 7 Plus - bought it 2 months ago and did not open the box till now. Is it possible that due to long time not being used/charged, battery may loose some of its capacity? Or are 2 months just OK and I have nothing to worry about?

    If the iPhone hasn't been used for approximately two months, it's not uncommon for the lithium ion battery to naturally deplete overtime.

    Here are some additional facts that Apple provides about their lithium ion batteries and charging capabilities.

    It doesn't degrade your battery performance in just 2 weeks. The phones were probably in the warehouse more than that. However, you may find it out of charge when you use it for the first time. Just start using it normally and the battery will start functioning optimally after a couple of charge cycles.

    The OP stated the iPhone has not been used in two months, not two weeks. Which would naturally lose some charge, but as you said, use the iPhone normally and charge regularly.

    Apologies. Misread it there.

    Storing the phone for 2 months will NOT harm the battery. Yes it will drain very slowly but there will be no detrimental effects from doing so.

    The only time damage occurs is if the battery is flat then you store it for an extended period. The battery will then deep cycle which is hard to pull back from.

    Lit-ion batteries can be stored for up to 10 years in a temperature controlled environment and not degrade too much. It is using them that degrades them.

    I've stored various phones for many years at a time. Always begin the storage at around 50% charge. Never had any issue even years later. They usually only drop a couple percent at most. People obsess over the batteries way to much. I've not had a battery issue since the nickle cadmium days.

    Have to wonder why you waited 2 months to open the box? Apple allows you to return an item within 2 weeks no questions asked. If the phone had defects or somehow didn't work right you could still return it to Apple but not as easy as it would be within the 2 week period.

    @chscag: bought it in quick sale from local apple reseller and did not have time to set it up, will ge to it next week

    Well, I believe apple knows best how to store its new products, hopefully they planned for scenario that some of its iphones spend few months unwrapped:) I will see soon...

    Any iOS 10 app will not be accurate when it comes to battery health, only a mere estimate. The only reliable source of testing real-time battery health is using a Mac with Coconut battery installed. iOS 10 changed what developers had access to, essentially killing off these types of iOS apps.
