    I found this from one of the members at XDA:

    With final version using Qualcomm modem, results should be much better.
    This proves my initial calculation based on GSMarena's test rating, namely, s6 has bad standby performance. I have made some calculation based on this graph. It seems, the battery dropped 7.1% in 6.5 hr standby overnight, which translate into 1.1%/hr in standby. This is VERY high.

    Good news is it can be avoided, it should either 1) be fixed by sammy; or 2) be fixed by users by turning off sync and data when in standby mode. The target should be 0.2%/hr.

    The S6 will have the best battery life of all flagships this year, so stop complaining-untitled-1.jpg

    Yeah but they had the high accuracy mode on, who the heck does that unless you're traveling? I think it's outstanding considering that one factor, talk about a battery draining mode...shessh.

    if the location service consume that much power in standby overnight, when it is not needed. That's something need to be fixed or disabled.

    That should only matter when you are using an app that requires location services. It's easy to see when that is happening because an icon shows up in the status bar too. I used high accuracy on my GPS, but maybe that's just because my GPS and current phone is so old that I need it to get a decent location and within a decent amount of time.

    Yes, and that is because Samsung's modems are worse than Qualcomm's. A better modem can fix the bad standby time, which is why I'm confident battery life figures will improve with the Qualcomm modem.

    Techno Buffalo, likewise, ok battery. Not so good camera. Buy recommendation only if a fan but not for overall design, performance and functionality.

    what Samsung modem is using so much power in standby?

    Probably their own Exynos modem 300 that they're planning on using for the Korean market.
    It's their first LTE modem, so I don't expect them to beat Qualcomm.

    While,you guys have talking battery life, I took time to watch the M9 reviews on Anandtech, The Verge, and Techno Buffalo to get a sense of the reviewer community on the battery and overall opinion of the M9 as it is one of the devices whose battery stats are part of this thread. Consensus seems to indicate that size doesn't matter as battery life is ok. It could be the chipset and firmware but I got the sense that the review versions were pretty close to final.

    If it lasts a full day use for me, then that's all I'd want.
    I think you're probably not alone in that thought. I'd wager most people only hope for a full day, knowing they will be on a charger at night. But I think that's shortsighted thinking.

    We tend to not think of our smartphones as a necessity, and we really use them as convenience devices. Remember that they are serious emergency tools, too. They can summon help, call for transportation, or find your way when you are lost. And the times when you really NEED your phone are invariably the times when we will find ourselves at the lowest in our battery reserves.

    So, I encourage the thought that this "one day" benchmark ought not to be for sporadic use, but for a full day of pretty much constant screen-on, GPS-active use, with a reasonable reserve at bedtime.

    I don't consider plugging the phone in with 2% left at the end of the evening a comfortable full day's use. That's using the device out to the limit (if it were a motorcycle, you'd have used your tank and drained your reserve, too). I want to know that if I have to use the phone an unusual amount, to unusual hours, or in a later evening emergency, that it will work, and I won't have to worry about it conking out because the battery's only good for squeaking by to the end of the day.

    I can't verify that statement myself but last year we saw something similar. Remember MKBHD reviewed the Korean version of the Note 4 and said it had terrible battery life. A couple of weeks later he got an American unit and his complaints were no longer valid. I'm not sure how much better the battery life will be with the correct modems but I've seen differences before. So far I've seen SoT's around the 4 hour mark and MAYBE they'll creep up to mid 4 hours or something, which would be decent comparing the specs and battery size. Anyways we'll just have to wait and see!

    As more current reviews come out, hopefully the review units will have more current firmware which may lead to better results.

    mmmm... do you have a link for this?

    I am just wondering because I understand in the past, sammy has been using Qualcomm components in US market, but this time around, they switched many things to exynos, including cpu and chipset. Its strange to think somehow LTE antenna is Qualcomm.

    I'm confident the Sony Z4 will blow anything Samsung or HTC can do battery-wise away.

    Regardless of SD810's, or the Samsung chip, QHD and so on, last years iterations didn't had that much difference in Mah batteries, but the Z3 just goes on, and on, so willing to take a punt that Sony can work their battery magic again in 2015.

    Z3 was good, but its really not magic, considering it has a 3100mAh battery for a 5.2' screen. And its even with s5 after proper lollipop update.

    What sony did right, is a large battery with phenomenal standby performance, that is something sammy, LG and HTC should learn.

    I agree it's not magic literally - that would mean David Copperfield ACTUALLY made the Statue of Liberty disappear...

    I have the Lollipop update flashed to the Z3, and have also seen a slight improvement in battery (maybe 5-10%).

    It's all horses for courses. I've used Sammy & HTC on and off (mostly off, due to the batteries), and know many others who have, and none have got even close to the Z3 for my day-to-day usage. If I hammer my phone, I'll unplug at 7 am, and still get to 11pm with 15-25% left. I've done the same with the S5, and it was dead by 6pm.

    I think Exynos 7 chip doesn't include integrated modem yet like Snapdragon does. So it must be paired with separate modem chip.

    Qualcomm offers separate modem chip (MDM series) along with fully integrated Snapdragon (MSM series). Apple is using their A series AP with qualcomm modems in iPhone too.

    HTC really dropped the ball this year. From the camera, to the battery life. Maybe next year they will finally get it right.

    That's a little harsh and I'm not a fan of HTC. They just did a GS5 type of incremental improvement.

    S5 didn't have a worse camera and way worse battery though. I'm not bashing the design, I'm talking the total package.

    Unfortunately HTC did worse. Even though s5's design change is incremental, it did improved upon s4 in all aspects, and battery is much much improved. M9, on the other hand, regressed in the screen and battery with nothing significantly better to show for.
