    This is a bit of research I'm trying and I hope there are some photography enthusiasts out there

    How many photos can you take on a single charge (say from 100% to 15%) Living images and rich capture off, most or all services off like cellular, wifi, bluetooth etc

    There is a new blog on the devices blog which says Mr. Stephen was taking about 1000 photos a day using the lumia 950 and 950Xl. I find that hard to believe

    https://blogs.windows.com/devices/20...quipment-ever/

    Has anyone tried a photo expedition with either 950 or 950xl? For example, using my lumia 1020, the most I have been able was 280 photos of 5+38/34 JPEG with flight mode on and GPS on - battery down from 100 to 15%

    Ps: I don't have either 950 since I don't have the money, still have the lumia 1020 and lumia 950s haven't landed in Kenya yet

    I would think that things like power banks and recharging on the boat may have been used, but not necessarily put down on the bog post as unnecessary clutter to a bare bones article.

    Original question still stands, how many shots with single charge?

    I suppose that it could make 1k photos with single charge if nothing else is draining the battery. If it is any use to you: I took 35min 1080p 60FPS video and lost about 40% battery.

    What OS are you on? I was trying to record my kids performance a couple weeks ago and the phone stopped after about 3 mins saying it was overheating too much!! This was while on 10586.420

    Sorry OP, I don't have answers for you, it's interesting question but it's not something I know much about. Maybe when I'm on vacation next week I'll take more pictures to see :)

    I got my new 950 today, I bought it as soon as the price dropped to 50 % of the original price. I'm still on my first charge and busy upgrading to 420 right now. As soon as my battery gets in shape I might give it a try.

    My 1020 is great, but I'm looking for a faster camera (among other things). People who praise the 1020 camera usually shoots nature pics, I want better point and shoot experience on moving objects. I remember trying to shoot people jumping in the ocean last summer, it all ended up with only water in the pics.. :/

    I just tested my 950 with 420, didn't have any issues recording 15 minutes of 1080 / 60 indoor with average temps.

    Hoping it was just my day 1 phone going bad on me. I have a new 950XL now and went straight to redstone. After 1 week, I'm pretty happy with the biggest concern I had, battery and heating levels of the phone.

    best way to test on how m,any photos it can take is to use proshot in timelapse option - flight mode on, gps off.

    I too encountered the overheating issue at roughly above 3 mins recording sometimes in Mar. I can't remember which build was that, should be the threshold build (now on redstone).
    I brought my son for outing on that day, reached the destination with roughly 71% batt left. Took some 150 photos, a few short videos (no turning off of wifi, background task etc, no battery saver), and whatsapp some photos that I've taken to my spouse before the turn off due to low batt. I swap out the batt with a spare batt and continue to shoot another 20-30 photos before we ended the tour.
    Now on the redstone build, the battery life is better than before, should be able to achieve a better result than the above.

    Soft reset, full charge, offline mode, BT, NFC, GPS off.

    I took pictures using Proshot timelapse, 5 MP every 5 second. I choose this resolution because I wanted to compare with the same when using the 1020.

    The Lumia 950 battery dropped from 100 % to 92 % after 100 shots.
    I stopped after that, afraid of getting the pic burned into the new display.

    Will try again with a higher resolution.

    This is my second battery charge so I guess it could only get better..

    When I think of it, checking remaining battery level after 100 shots is a better way to measure this than running it down to 0 or 15 %, anyone agree?

    maybe run it for longer like 400 shots. but that is a really good rate. I have an extra reason to have the 950 now :-)

    I am more than pleased. The back doesn't creak at all, it doesn't get hot during charging (well exept for the first time when it still had 10586.11 and I did the first set up at the same time).

    I'm sure that the 1020 will have more than 92 % left after 100 shots. It doesn't bother me tho, I never take that many pictures in a day anyway.

    Well, sorry to disappoint you but the 1020 wasn't able to take that any shots on a single charge. I once did a timelapse with proshot, it did 360 photos while batter dropped from 90 to 15%. But it could have gone more if GPS was off

    Lumia 950, 400 5 MP shots every 8 second. The battery dropped from 100 to 83 %.

    Lumia 950, 100 19 MP shots every 8 second. The battery dropped from 82 to 72 %, a small difference compared to the lower resolution in the first test.

    Lumia 1020, 100 5 MP shots every 8 second. The battery dropped from 100 to 92 %, just like the 950 in the first test.

    I am pleasantly shocked. How did you do that on the 1020? I really wish I had my 1020 right now (curse that thief )

    Haha, I don't know how to answer that. Same settings as in the first test, only longer intervals with 8 seconds. The battery wear is 5 % according to Aida64.

    I took a bunch of pics of my daughter and her friends at the park the other day, approx 150, and went down about 15%, but I was doing a few emails/texts too, during the same time period, even sent a few MMS pics texts to kids' parents.
    This seems inline with what most others are seeing, about 1%=10 shots.
    I bet if you went to 500 or something though, that the drain would be higher; I don't think the battery measurement is as linear as it should be. Those weird jumps in .420 are part of my suspicion, plus it seems pretty common that 100%->90% is very slow, and then the drain accelerates some.

    Update, as I got a (slightly) bigger sample-size, last night. Went to the Boston (band) concert here in Seattle, and shot 96 pics, and almost 10 minutes of HD video, plus texted a bunch of pics to friends (mostly whom I used to party with a LOT and go to other concerts, back in the day).
    All of this was 32% of my battery start-finish, but did include those texts, which IME, are VERY battery intensive, particularly MMS with big pics.

    It's a bit tricky to extrapolate from here to max battery, but I'd guess you'd easily get 400-500 shots, if fully-charged (and you weren't texting them around, like I was). I find the 1000 shots hard to believe too, based on this. Maybe, if you turned *everything* else off, all data sources, any background processes, but my estimated guess would be more like 6-700 then, clearly a guess though.

    I was really pleased with my no-flash photos though, the camera aperature really excels here, I had very few pics that weren't decent quality, maybe 10-15%.
    That's shooting in mostly dark, with some crazy-bring flashes of light, as those of you concert-goers (I was quite the partier/attender back at some point, I've seen Boston twice, Scorpions 4 times, I could go on...) know, FAR from ideal conditions for any camera, much less a phone... Good stuff, I continue to be impressed and pleased with my 950XL.

    Edit: just realized I also texted a 45-second HD video to one buddy too, oops, that probably seriously ate some battery...

    Update:
    Yes! It only took two crashes (and recovery) of Windows 10 Explorer to actually copy the files, via USB-C (actual, quality USB-C cable), instead of the frequent 5-10 crashes to copy a series of pics or other files, from the phone (mostly SD, 80-90 read-speed mbps card).
    Windows 10 Desktop and/or Mobile fixed some stuff here, maybe the desktop added a longer timeout or retry logic, but either way, it's much better than the 200's and 300's builds, or it's the desktop. Tricky to figure out, without wading through changelogs and/or reverting a bunch of stuff.
    Obviously, zero crashes would be ideal, but this is MUCH better.

    In case anyone cares, first crash was enumerating the files (only maybe 15-20), second was starting copy, after a couple of files (that never made it to the target disk/SSD), third one went straight-through, copy complete.
    I tried to diff afterwards, but that wasn't happening, crashed again, twice, gave up.

    Anyway, Chintan G., hopefully this gives your some more data, and impetus to move towards a new 950/XL!

    One more thought, on this topic.

    It would be fairly easy, if you had the SDK, and a development environment set up for mobile (I haven't, since 8.0 days, not even sure my tools would work with the newer SDK), to script or similar, to test the actual number of pics.
    You'd just need to:
    1. disable all radios and background stuff, except the camera
    2. take pic sets, say 25 at a time
    3. check the battery
    4. save the total number of shots (could be done later though, to avoid this cycle, just count via USB or similar)
    5. if battery >=10% (seems like a safe margin) then loop back to 2

    Easy-peasy stuff, maybe someone with a current dev branch could scribble this up, given the simple pseudo-code?

    this is way beyond me . I would test some things out but I don't have a phone now. I'm actually considering getting a dslr - the Nikon D5300 looks good
