Samsung Galaxy S5 16GB Black Unlocked (SM-G900A) AT&T

• This phone has been reviewed to death, so I will not bother reviewing all the small details. I did, however, notice that no reviews mention wakelocks, so I would like to take a moment to discuss those. I will also tie this into the battery and battery life.At home, my S5 has amazing battery life. I consistently get nearly 6 hrs. of screen on time with a single charge. However, at school (a large university) my battery life takes a nose dive while on wifi. A tl;dr explanation of what is happening is that the android operating system has a bug where busy wifi networks are able to wake your phone up while it is sleeping (keyword: wake locks). This means your phone cannot go into a consistent \"deep sleep\" after you lock your phone and it will continue to drain your battery even when you\'re not using it. Feel free to google it for more info, but as of now, there is no fix. A quick fix for me was to download an app called MacroDroid. I set it so that when I am connected to my university network and I lock the screen, it will automatically shut the wifi off. When I turn the screen back on, the wifi is turned on automatically. Disclaimer: I am running kitkat right now, lollipop may or may not fix this issue.Related to this is a problem my S5 seems to have when I change specific things. For example, both after installing a microSD card and syncing my text messages from my old iphone to my current phone, the phone would not go into a deep sleep. I was able to fix these issues by clearing my phones cache and clearing the cache for the associated apps. I\'ve always been able to fix this issue, but I feel like it shouldn\'t be happening at all in the first place.If anyone cares to know, I will describe how to prolong your battery life below, both on a day to day basis and its lifetime overall.To extend day to day battery life:1. I immediately turned off all gestures (apparently they can get toggled while the phone is in your pocket and use up battery?)2. Turn off location unless I\'m using it3. Disabled all the random apps that come preloaded on the phone and you can\'t deleteIf you are having issues with your phone\'s battery life, try using Greenify, which will let you hibernate apps that may use up battery with one click. You can also download an app called \"System Monitor\" (the Lite version is free and works fine for this purpose) and you can use it to monitor the CPU speed on your S5. If, while the phone is locked, the phone is not in \"deep sleep,\" something is wrong and it will cause your battery to die faster than it should.Note: The first time you turn on the phone and as the phone is installing all the initial updates, the battery will probably drain very fast. This is only because the phone has been off for a long time and the calibration (so to speak) will be a little off. After you charge your phone completely it should go back to a normal discharge rate.To extend the overall lifetime of your phone\'s battery:1. Do not leave it in your car when it is very hot (> 80F) or very cold (<35F). It can do irreversible damage to the battery.2. Limit the number of charge/discharge cycles. I.e. charge your phone when you have to. The best thing to do would be to only charge it once it\'s below about 20%, and when you do charge it, charge it all the way up. Unplugging it as soon as it reaches 100% is recommended.3. Don\'t leave it at a low % charge for a long time, it\'s unhealthy for Li-ion batteries.There is no need to \"cycle\" your battery (you do that with Ni-Cad batteries).Other than that, it\'s a really nice phone and being samsung\'s \"flag ship,\" there are a lot of available accessories for it. I am using the Spigen Slim Armor case and really like it. I also would highly recommend a tempered glass screen protector, it has a much better feel than a plastic screen protector.Lastly, I had no issue switching from an iphone 4 to this phone. It took a bit to get used to, but I was quick to realize the many new benefits. The new screen was daunting at first, but my hands are big enough to hold it, and it is a lot easier to use and see.
• My previous phone was a Samsung S2, which I really liked & intended on keeping, but the charger port went bad and it would do all sorts of bizarre things, including drain the battery in 2 hours. So I took the plunge. This is a great phone, but here\'s the beef & why I didn\'t give it 5 stars... ATT is why. I\'m not singling ATT out for any particular reason other than the deceptive way they treat customers. The price you will be quoted here on Amazon is NOT the price you will actually pay. They warn you there are other fees, but will not tell you what they are other than the $40.00 initiation fee. Well, people, there are so many fees you\'ll pay a huge amount over the online quote. And the $80.00 a month charge for the 2 gig mobile sharing plan listed here is likewise not really what it\'s going to cost you. All those unlisted fees and surcharges will cost you $94.88 in the end, almost $15.00 a month, or $180.00 per year, over what you thought you were signing up for. This has gotta stop. Won\'t one of you politicians submit a bill requiring service providers to tell you up front EXACTLY what all the charges are going to be? This is like living in the Ukraine.That said, the S5 is a great phone. More bells & whistles than you can ever use. Samsung, why can\'t you pre-load all your phones with a pdf of the owners manual? That shouldn\'t add hardly anything to the cost & would really help your customer base. For the uninitiated, these phones come without directions, so you\'d better have a PC at home so you can go to Samsung\'s website to see how to install the SIM & memory card, \'cause the included Quick Start Guide doesn\'t tell you that important procedure.The camera is a fantastic improvement over the S2. Much clearer and many cool options, but a digital camera will take much better pictures, so don\'t expect miracles here. The size of the lens does matter, so while the marketing data on the camera has impressive numbers, my 1994 Canon 4 meg digital camera takes exponentially clearer pictures than this phone. It\'s all in the lens.The phone is really thin. Take an S2, make it thinner, stretch it vertically, and you have the S5. Some complain it feels cheap. Really? Not to me. It\'s light, thin, and compact. Considering what this phone does, I\'m impressed with it\'s diminutive size & weight. One change that I\'m finding difficult adjusting to are the Home & Back buttons, and the new one on the left you press to dispaly which apps were recently in use. This last one is really handy, as we all tend to use mostly the same handful of apps, and this is a really quick way to open them up.The battery life is wonderful. A charge lasts me about 2 days with substantial use. The battery is about a third larger than in the S2, charges very quickly thanks to the higher tech charging plug, and even still accepts the old version of a mini usb port charger so in a pinch you can still use your old charging cables, especially if you have a car charger. I really like that.
