    I've tried so many suggestions from power saving, app deleting, etc, etc, etc. Nothing seems to make a real difference and I've seen many posts from folks suffering from the same crazy situation I have. My 2 year old iPhone 6 battery life was far superior, and I didn't have to do any of these crazy things that don't seem to make the proper dent.

    While I could easily go back to my old iPhone, I simply cannot abandon this phone's amazing camera. Is there a bona fide fix for this crazy battery situation?

    I apologise for not answering your question, but at the moment my iPhone 5s is giving remarkably poor battery life, for the last month or two. I've no idea why. It used to be excellent. So these things are not limited to Androids.

    I'll request that your thread be moved to the S7 forum, where other users may be able to suggest.

    Sorry to hear, I know some don't have that, but I do, every Android phone, from Note II (battery bulg repeatedly) thru s5 and BB priv and now s7. 10% per hour when in use.
    Two iPhones , 5s and 6s plus, same type of use, very lite impact on battery, 5% or less per hiur.

    If you don't need it, try changing your email from instant push to say check every 30 minutes. I've no idea how your screen is 7% mine is always at least 30% and I have the brightness around 30-40%. But my battery lasts me from around 8am-11pm (usually has around 30-40% around then).

    Do you get a good signal on your phone? That'll burn your battery. Also do you have Wi-Fi enabled?

    I recently upgraded fro an S6 to the S7 and my battery life has improved immensely. The battery settings predicts a 23 hour life on a single charge for me. I've noticed that I still have plenty of battery life at the end of my work day. Because of the great battery life, I didn't have to resort to your typical battery saving tips other than turn off Google location tracking and my Wi-Fi when I'm out of the home. I've left every thing else (e.g., GPS) turned on all the time.

    I also don't have any data polling apps like Facebook installed. For your case, I would guess you have some 3rd party app installed and running amuck, or you're in a weak cell tower area, or maybe your battery is defective.

    You really can't compare an iPhone battery to an Android phone battery. Android allows for many things to be running in the background that iPhone just doesn't allow. Tweaking for your use is a necessity.

    I agree but it's hard to get people to understand that. They're used to using the phone right out of the box without any user setup

    My battery life is pretty bad as well. I'm getting a drain of 7-12% per hour almost regardless of how much I use it. If I do a video call or watch Netflix, it goes as high as 20% drain per hour. It's pretty upsetting considering this thing has a 3000mah battery and it used to be under 5% per hour for the first couple of weeks I had the phone (and no, I haven't added any new apps that are consuming battery). I've been thinking about doing a complete reset, and setting the phone back up again, but that's very time consuming and shouldn't be expected from the user. I think it's just Android and these phones need 4000mah batteries to last all day.

    I've removed Facebook and enabled power saving on all apps. I still lose 10% minimum per hour, and it's brutal for me as I travel often and am using my portable battery so much more on my new phone than my 2 year old phone (even though I use it in the same fashion).

    I went back to a S7 recently from a HTC M9 and am delighted with it.
    At first the battery life was poor but I did a Hard Reset and battery life is much improved.
    I am running Nova Launcher, Package Disabler Pro to clean out all the unwanted junk and bloatware also have Power Saving Mode enabled.
    I am a reasonable user of Data during the day for emails and web browsing.
    I charge my phone in the evening and going to bed around 11.30 pm have 98% battery showing, at 8am 94% and now at 17.00 pm 60% showing.

    I'm very happy with my S7 battery life. I've owned the phone for a few weeks, and have not run it down once over the course of a day

    I try to make sure this isn't a reason, so I post this when I see battery questions.

    Are you using the stock charger and are you charging to 100% (at least some of the time)? My phone was draining really fast, 100-0 in about 6 hours. I learned that it was my wireless charging pad that was causing the issue. If I charged it to anything below 100%, it would drain fast. But charged it to 100% and it would last like "normal" (8am - 11pm). This was a good wireless charger too and it worked great with my S5. But something about the S7 battery didn't like it. It makes me wonder how many battery issues are caused by chargers.

    Just throwing it out there since I was shocked that was the cause of my fast drainage (and I figured it out when I got a replacement phone and after multiple factory resets on both phones - never fun).

    USB a/c adapters vary and non of my seemingly good ones from Apple 6S+ and iPad work. To credit if S7 and Sammy I would get battery not charming properly notifications.

    With ios and iPhone I found an excellent battery app that would report on health and actual charge, t h at helped isolate cables, adapters even a bad Anker 5 port charger which caused over heating and other issues.

    Update: good tips for my S7 situation. Enabling WiFi significantly has slowed my battery drain. I really prefer Sprint's signal traditionally, because it's a very strong LTE signal that's more reliable than WiFi. However, that could've been a huge factor (?).

    Just make sure to keep location history, improve accuracy turned off under location setting. And smart network switch should be off if WiFi setting has it. Other than that there is no need to tweak settings much. But doing those things will make big difference on stand-by drain. it wouldn't hinder using any location based app.

    I had similar issues. I'm 99% sure it was something wrong with the phone radio that was all the time attempting to connect to LTE (where my chip is capped to 3G only) so my fix was to only allow 3G and 2G.

    However I also did other things before that that might have also helped:
    - On location services, disable wifi and bluetooth optimizations/improvements
    - Sweep through all settings (I can't remember exactly where they were) and disable everything related to auto reporting such as sending reports to google and samsung, and automatic system scans, there's a lot of hidden garbage like that, just make sure you go through all settings and disable as much as you can
    - On another desperate attempt I purchased package disable pro, and disabled lots of stuff, I don't if it helped or not, but at least there are less background services running.
    - Look for any apps that might also do too much work in background, the best test is to unplug your phone at 100% at night and after ~8hs of sleep and completely no use (not even moving the device around so doze can work) take a look in the moring at the battery usage, you shouldn't really have many things there, only phone idle, phone radio, android OS and android system, and probably a tiny bit of screen and google services, but really nothing else. Make sure you do this with either plane mode or all internet disabled so you don't get notifications (and you will sleep better!)

    Wow, 0.5%/hour? Do you turn everything off or something? According to GSam, my S7 consumes about 2.5%/hour while idling in my pocket or on my desk, but I don't turn anything off. Wi-Fi, Bluetooth, NFC, Location, everything is on.

    Actually using the phone though, it ranges from 5%/hour to 20%/hour, which is pretty high, but I came from using a Lumia 640, and surprisingly, both the idle and usage consumption rates of my S7 match the battery consumption rates of my old Lumia 640.

    I don't use wifi because don't need to so that's off, BT and location are always on, NFC is off. Have about 65 packages disabled and and use aggressive doze.
