    Remember - Doze basically needs the phone to be still - like on a desk. It can't be in your pocket or bag or purse and moving.
    So for a mobile device, not exactly a point for savings (Doze is for sleep efficiency) Folks seem to forget that there were also great tales of battery life for Lollipop that have not exactly panned out. The main battery drainers for a device are the display, GPU and cell radio in weak areas. There will be minimal SOT improvements since the majority of power consumption is hardware related.

    Optimized power savings would be better served if there were focus on more efficient GPU governing and cell radio management (this is chipset specific- not Android). If people like brightness cranked up, that pretty much kills a lot of any expected battery savings, since most of the weight is display related- Unless of course in a weak signal area or using an app that is trying to calculate math and push to the full 1440p. Those two scenarios actually drain more battery than the display on the Pure. You can tell what apps try to draw to 1440p with math- the device runs HOT. Still odd how it runs ten degrees hotter than the Note 4 that has a higher micron fab. Probably has to do with the 418 GPU beating itself to death trying to keep up with true 1440p instead of scaling to larger pixel areas (720p or 1080p).

    Again not talking about web or video, but apps that actually force the 418 GPU to manage every pixel to calculate geometry and physics. That is taxing.

    Sounds about right. Every phone I have owned if the signal is weak it kills the battery. You think devices would be smart enough now to stop trying to hard to get a signal.
    So my signal at work hovers around -94dBm 46asm. Would you guys consider that weak?

    That's very good. The dBm relationship to signal reception is not proportional, so even a signal of 109 dBm does not drain the battery too bad. There appears to be a bigger drop-off in efficiency at about 114 dBm. That is the case at least with the devices I have used with Verizon.

    Well, my cell radio uses more than my screen. Not using a lot of data or any other indicators excess use.

    It is the cell standby? If so there is a known bug with 5.0 that is causing this issue. I believe it is the cell standby.

    Dunno, thankfully I got a lot of those 2000mah chargers free at a conference last week so I can stop panicking if I'm away from a charger for over a few hours.

    I don't have the quick charge version but I have the one with IQ.

    And I stand corrected I have a 13,000 Mah external battery charger

    Looks like I can get 4 1/3 charges out of my device.

    Yeah this one is IQ too. If my Pure is below 60% ish the charger cuts off immediately. I think it's a bug in the quick charge implementation in the Anker with the Pure drawing more than the overcurrent protection will allow.

    I will have to test this out once I decide to buy the device.

    Can you turn on the charger after it cuts off to charge the device? It's really not that big of a deal as 60% should be good to go for awhile.

    I have an 10,000 Mah Anker charger but I have yet to try it yet. I usually only break it out for vacations since I work at an office at a tech company and there are ample places to charge if need be. I really should try it out when I get my replacement Moto X since it seems some people are seeing issues.

    My Moto X, before it went nuts anyway, was getting me about 24 hours with almost 4 hours screen on time. Overall Android L has so many bugs that impact battery life all 2015 flagships have suffered. Cell standby issues, Google Play services going crazy when off WiFi and you have a weak signal, higher then normal drain with bad signal compared to KitKat; it's just a mess. My X will drain slower in a weak signal them my S6 does but it's not much slower. I don't give a hoot about Doze at this point, I just want L's bugs ironed out. Without that Android is going to continue to have serious battery issues and Doze won't be a band-aide big enough to help.

    If the phone is below ~60% there's no way to use the charger.

    I plan to write Anker about it but bought it before a long trip I just got back from so have not had time yet.

    Ok well that is not going to work. I really do not want to buy another charger. Could you let me know what Anker has to say about this. I will try it out too once I get the phone. This worries me.

    That is a nice one! I might have to pick that one up if the current on doesn't work. I will just end up selling my current on to help cover the cost of this one.

    Added it to my wishlist.

    When I was at work then home the other day, I got 3hr 50 minutes of sot and had about 25% battery left when I plugged it back in. When I'm at work I will check texts and facebook occasionally, maybe do some googling but not much else.
    Today I used maps, driving mode (for about 40 minutes total), took and posted a few pictures and purposely spent a bunch of time on my phone at home. Sot was 3 hours 30 mins w 11% left.
    Not great.
    I feel like if I take more than a few pictures with this phone or do anything out of the ordinary, the battery will die, and since it's not removable...
    Between the battery and it getting hot, I might send it back.
    I love the way it looks and coming from suckwiz and an s5, this is a breath of fresh air..but I never worried about the battery in my s5 and the very few times it ran out, I could swap in a fresh one.

    Fwiw, your app usage appears a little high. What's high in there? Probably the navigation. Everyone's usage and needs are different but I think it's a good practice if you're using maps/navigation to be charging with a turbo charger in the car at the same time.

    They are about the same based on reviews. Considering same chipset, battery and display size- makes sense.

    The problem is the same with the G4. The GPU on the chipset goes into demon mode with any app that tries to draw full 1440p and uses the GPU for calculations. This is why some 3D games you would think would run hot do not (scaling to 1080p) and some apps like Maps and others run hot and drain the battery. The 418 GPU is way over it's head as far as pushing 1440p beyond a UI, video and more static functions like web browsing. An exception to web browsing though is Chrome, since it also tries to leverage the GPU with some of it's graphics extensions- depending on what sites are accessed.

    This is also why the 805 chipset in the Note 4 performs better, since the GPU can handle pushing 1440p without beating itself to death. It runs ten degrees less with GPU leveraged 1440p content. VR content is a good litmus, since uses the GPU to draw to 1440p in order to provide the split of 720p (two displays for lenses). VR content is very GPU intensive and the Pure gets over 120 degrees with it. Ten degrees warmer than the Note 4.

    Folks should appreciate there is a huge difference scaling graphics down to 1080p and using true 1440p. Even though all 1440p is shown on the display, the GPU works a LOT less geometry and physics calculations treating the display like a 1080p. A lot of iOS games draw 720p and 1080p rather than full 1440p. Ditto for Android.
