    I guess that all those hardware goodies - Snapdragon 810 & 1440p display, maybe combined with Windows 10 eat up more battery than we may expect.

    From the official Microsoft Mobile website: Search results for Lumia 950 XL, Lumia 1520 - Microsoft - Global

    - Lumia 950 XL Lumia 1520
    Max Talk Time (3G): 19 25.1
    Max Standby Time: 12 days 32 days

    [HR][/HR]
    One interesting thing of note is that under "Other user interface features", the 950 XL has "tactile feedback", which isn't listed under the 1520.

    Liquid cooled and maximum output... I was always cautious about that part so I wasn't expecting equal battery. Still. Glance cuts down all the useless mumbo jumbo of wasting battery just to check something out.

    Screen doesn't account for the stand by drop of so much. Quite disappointing.

    I'm guessing the differences are more due to software and/or test methodology than hardware. Comparing 10 to 8.1 is a huge chasm of variables. We don't know what services are allowed to run in the standby test that would so drastically affect standby. For instance, if Cortana is running during the 950 test but not on the 1520...that's a pretty big deal. I can't speak to the differences in talk time...but those are smaller and again, we don't know what the test methodology was.

    While definitely interesting..I wouldn't draw any major conclusions until real-world comparisons are made and published.

    I've generally been of the opinion that high res and large screens do take up more battery. Maybe the reason why they aren't too bothered is because it isn't the critical factor.

    In any case, more battery life is always looked favourable on by actual users. Phones have progressively gotten larger and larger batteries, without significant improvements to life, so that just says that they're getting the whole package to consume more power.

    All smart phones have a bad battery life. The thing is optimization, setting the screen. Do Not put your screen on auto brightness. Also, the applications using background data eat up a TON of battery. If not using wifi and Bluetooth turn it off.

    My phone used to last 6 to 8 hour depending on the use, after insuring I followed these steps I get about 14 hours on average of battery life. I work in an office so I'm ALWAYS on my phone.

    The sensors eat battery, while the phone is active the sensor is on. I've tested this on separate occasions and found, keeping a screen at 20% more or less (no more than 30%) statically gives me great results on my daily uses with emals, texts, calls and applications used.

    I have a two plus year old phone, I can't wait for this upgrade. I almost settled for the note 5, thankfully I waited. After reading the reviews and talking with friends and colleagues that have it, regret is they tell me.

    Isn't the sensor already on? That's how it detects glance, whether your phone is to your ear or not, whether the phone is face down or not, etc.

    Whether or not you have auto brightness on shouldn't be that much more tolling than those other functions that the sensor is already doing.

    The sensor doesnt matter, pretty sure its always on regardless of what you have it set to. But if you constantly have your screen set at 20-30% brightness then of course its going to use less power than having the brightness higher. Its not the sensor itself thats making the difference.

    If you are on your phone inside and outdoors, that feature kills the battery because it's constantly changing to illuminate in the correct environment.

    If you turn off the auto brightness, there is no constant fluctuations with the software due to changes with artificial and natural light. It makes a difference just like leaving the Bluetooth and wifi on. Run a test over 3 to 4 days with the settings on the links.

    Nothing says "great phone" like having to disable all the unique features. This is, hands down, a MS issue. One person hit the nail on the head, ALL high ends have bad battery life. Whats the #1 complaint about phones, the battery. If MS would take the approach of battery life is #1, maybe they could have squeezed a larger battery in both phones. I SERIOUSLY doubt someone, unbiased of any OS, would look at 2 like phones with one having 30-40% longer batter time and choose the lesser because their friend has it. I would LOVE for MS to take that approach with the entire phone line. You can only optimize the OS so much for the battery. Turning off everything will probably only yield 2-3 more hours. Why would someone buy that when they can get another that lasts longer, with ALL features enabled. That was my biggest beef with the 1020, that bump to the back was a complete waste of real estate. Imaging the battery they could have packed in it and had a smooth back? YES IT WOULD BE HEAVIER. But we arent talking having to check it on an airplane heavy. Another couple ounces and having a battery that can shoot for more than 2hrs or last 2 days, ill take one!!

    Only if you assume battery life will drop much at all. Reading these forums is sometimes like reading the Brother's Grimm. Ever hear of Henny Penny? I think her descendants must be forum members.

    Has anyone checked to see if the standard tests for talk and stand by time have changed between when the 1520 was released and now? Could be apples and oranges. And aren't the 1520 values as of its release date, meaning it may be MUCH worse now with 8.1 and 4K video and Hey Cortana, etc.. Has anyone confirmed a 1520 really does have 32 days of stand-by? People ate spinach for decades because the govt got a decimal point wrong regarding how much dietary iron they said it had.

    Thats not reassuring, about the 1520. If the battery life WAS better in pre release cases and got worse.... See where Im going? Why would MS advertise less than expected life. Yes, with new OS updates and features, the battery life will get worse, always does minus some programming error that gets patched. Even if its a new battery that we are luckily able to replace.

    I don't think you are following. The method used to determine an advertised battery life may have changed in the last 2 years. The way they test car mileage today isn't the same as it was a few years back. I am pointing out that nobody seems to have checked on that. If it changed and the 1520 was retested the way the 950XL was, it might have much worse values. And, as I pointed out, erroneous data happens. The US govt erroneously published that spinach had mega amounts of iron but it was a decimal place error. Wasn't corrected for many many years although I'm sure professional nutritionists had a good laugh among themselves. So the figures are interesting but nothing to get freaked out about until we know real world results and/or verify none of the possible explanations I mentioned are in play. And yes, calling unverified published numbers a fatal head wound meets my definition of freaking out. Particularly when the biggest variance is stand by time. So for the sake of argument, lets pretend the stand by values are apples to apples and no mistakes. The XL stand by time is 12 days. Tell me what fraction of ONE percent of 950XL owners will ever use the phone so little they go 12 days between charging. And for all we know, someone at MS tells a tech we need to submit these numbers NOW. how long is stand by time? I dunno, Its been 12 days since I started the test.

    I'm not saying any of that happened but its NUTS to freak out until we know they didn't (because things like that have happened plenty of times in history) or until we have real world hands on data.

    With wireless charging there is no battery problem. I have Qi chargers everywhere I go (thank you AT&T clearance sales). If you need to go a while without access to a charger (airplane, bus, etc.) you can simply bring a backup battery. I would gladly trade off a little battery life for a superior phone experience.
