[Samsung Galaxy S7 Active Guides, News, & Discussio] br0adband:
Ok, so I've had this GS7A a few days now, did one or two full resets to get used to what I could disable with Package Disabler Pro (worth every penny, seriously, since we may more than likely never see a working root) and I have to say that I am pretty damned impressed with the battery life. Yes we all know this magnificent beast has a 4000 mAh battery in it so that has something to do with the lifespan obviously, but I wanted to post about my experience and perhaps try and stir up some discussion since this subforum is basically dead for the most part.

I know most discussion is over in the GS7 thread since it is the same hardware in a different case but even so - it's actually not the same device since it has a smaller 3000 mAh capacity battery so, if anyone is interested in sharing their battery life info and experience by all means do it.

A caveat:

Right now I don't actually have cellular service with this GS7A because it's currently still carrier locked to AT&T and I haven't gotten around to purchasing an unlock code. I'm not an AT&T customer, never have been, and since I got this device from a trade done through craigslist the person I made the deal with wasn't the original owner - he did state he found the phone in a casino bathroom here in Las Vegas (that sort of thing happens hundreds of times a day here, seriously) and yes the IMEI is blacklisted so I don't know if the original owner reported it as lost or stolen and since the blacklist system doesn't differentiate then it doesn't matter anyway.

Having said that I will state that I use Google Voice for all my "phone calls" and SMS/text duties these days so I don't actually need cellular service as long as I have Wi-Fi. Google Hangouts handles all that just fine so, I'm stating this here so you'll understand that I don't use the cellular radio at all, the GS7A stays in Airplane Mode constantly and with Wi-Fi enabled (and yes Wi-Fi is always on).

Yesterday I did quite a bit in terms of actually using the GS7A: I listened to a lot of "police scanner" streams using Scanner Radio Pro, I watched the entire Presidential debate on the GS7A using CNNGo, I watched maybe 30 minutes of video on Periscope (Scott Adams, creator of Dilbert), listened to my own music (Opus 128Kbps encodes) using GoneMAD for maybe 3 hours total since the last charge, listened to a radio station from back home in Virginia using TuneIn Radio for maybe 2 hours, read a lot of articles using Flipboard, and various other things including hitting the Play Store to check for updates as well as checking Gmail maybe a few dozen times during the day. I also did two runs of Geekbench 4 and two runs of Antutu during this period before these screenshots were taken so those were a hit on the battery for max CPU/GPU usage for several minutes each as well.

Also, I keep the screen brightness at about 40-45% on the slider, but I did go out for a walk yesterday lasting maybe 30 minutes and set it on Auto to compensate, probably had the screen on about 5-8 minutes in that time at ~full brightness.

So understanding all that here's what I've got currently from screenshots I just took like a minute ago:

Looking at that kind of battery life, just shy of 2 full days and barely cracking the 50% point, I can guess that if I did have actual cellular service I could easily get 1.5-2 days use of this device regularly which is truly astonishing. The last phone I had that could give me battery life even close to this was a ZTE Zmax which literally gave me 10+ hours of SOT on a regular basis (the 1280x720 display on that really saved a lot of battery life, and the Super AMOLED on this GS7A probably helps considerably as well).

I am truly impressed by this, and I have to wonder what kind of actual battery life I could get with a) cellular service working normally and also b) root so I can do even more tweaking as well as c) an unlocked bootloader to allow for a custom kernel.

And I haven't even enabled the Power Saver or Ultra Power Saver modes at all. :D

So, what's your battery life like using the Galaxy S7 Active? Anyone? Anyone? Bueller? Bueller?

EDIT:

Finally died and shut itself off but I watched a few TV shows off my Play Store Movies and TV account to keep the screen on and the Wi-Fi active and here's the final result - I never kicked in the Power or Ultra Power saving modes, I simply let it go till it shut itself off:

Mind you if I had just continued to use the GS7A in a typical fashion with audio streaming, Flipboard reading, etc, and not continuous screen on video viewing as well as the Wi-Fi I'm sure it would last 3 solid days without any problems so again I should (or anyone really) should be able to get an actual solid full day of use from this device reaching possibly into the 1.5 to 2 day range with cellular working normally.

Damned impressive stuff, it really is. :)
