    I'm planning a backpacking trip in August and since I want to pack as light as possible, I wonder how often I will have to charge an iPhone X to determine how large of a power bank I need to bring with me. Seems like Apple doesn't state any standby battery life data on their website, so do you think it's possible to stretch a single charge to a full week of use with the following use scenario each day:

    • Listening to music through wired In-Ears for four hours (80% volume)
    • Using the screen for 30 minutes (this includes choosing and switching between music) – the heaviest app used would be Google Maps (with downloaded maps used offline)
    • Having the phone on airplane mode for all but ten minutes a day
    • Bluetooth might be active for a few hours to sync with my Apple Watch
    • Using the power saving mode all the time

    Nothing like getting away from everything and enjoying nature.

    I kinda don’t see your point here. Could you elaborate it a bit? Thanks. :)

    Are you able to get a battery pack? Walmart has a 10,000 mAh battery pack for under $20 and it works really well.

    I'm not sure whether this is the best weight to capacity ration out there – my Xiaomi one weighs 212g with a capacity of 10,000 mAh. But I'll definitely look around the web for lighter options, so thanks for your suggestion!

    Yep, looking forward to that trip a lot! It's about time I get away from the office life.

    I do already have a Xiaomi one with 10,000 mAh capacity, but if possible, I'd like to get a smaller and lighter (thous also lower capacity) one to save weight.

    Without a battery pack, I could see one day of that described usage draining the battery completely.

    Since a battery pack can't supply 100% of its capacity to another battery due to charging losses, I'd plan on getting a battery pack with at least 1.5X the power you're going to suck out of your iPhone each day for the entire trip.

    For example:
    If your iPhone X has a battery capacity of 2600 mAh, you'd need a 3800 mAh battery pack to ensure a full charge w a little extra left over.

    Multiply that by the number of days you're planning your trip.

    If you use any mapping software- it'll drain the battery really fast.

    20 minutes offline use + 10 minutes online use + 4 hours music via wired headphones will drain the battery of the iPhone X completely? If that's the case, Apple screwed up pretty bad.

    You're going backpacking. Forget about listening to music and just enjoy nature.

    I don't think there's anything wrong about listening to some of your favorite music a few hours a day – listening to the right track at the right moment can be very enjoyable, I think. But yes, I agree with you that enjoying nature is the important part, so that's what I'll be doing the majority of the time. ;)

    The new Anker 10000mah is the way to go. Better safe then sorry. 6 ounces won’t break ur back.

    Anker PowerCore 10000, One of The Smallest and Lightest 10000mAh External Batteries, Ultra-Compact Portable Charger, High-Speed Charging Technology Power Bank for iPhone, Samsung Galaxy and More https://www.amazon.com/dp/B0194WDVHI/ref=cm_sw_r_cp_api_i_8egpDbWEBZW74

    If you had the iPhone XR your battery would last longer. Given an iPhone X I would say you should last at least 2 days per charge.

    When you refill the best way is to charge your iPhone up to 80%. Avoid Bluetooth!

    All power banks are less than 100% efficient so 10000mah is more like 3 charges. 6000mah might be less than 2 charges.

    So a 10000mah bank should allow you to go 8 days without sweating or desperate measures.

    Bring 4 of that huge-ass battery pack and leave them in your backpack.

    That's almost a full kilogram worth of weight to carry around all day – in addition to the backpack, tent, sleeping bag, water and so on – at that point, I'd rather just leave the phone at home alltogether.
