Samsung Galaxy S7 Battery Replacement

Released in March of 2016, the Samsung Galaxy S7 took the smartphone market by storm with its impressive camera, large display, wireless charging capabilities, and its certified water-resistant rating.

The smartphone comes equipped with a remarkable 3000 mAh battery that unlike early Galaxy models, is not removable. If your beloved Galaxy S7 is constantly running out of juice, take advantage of CPR’s helpful battery life tips, and step-by-step DIY Samsung Galaxy S7 battery replacement guide. With a little help from the CPR experts, your S7 battery will be charged and ready to go in no time.

About Samsung Galaxy S7 Battery Life

Like almost every other phone on the market, the Galaxy S7’s battery will inevitably lose some of its capacity over time. In fact, Popular Mechanics claims that a premium lithium-polymer battery may lose about 20 percent of its capacity after 1000 charging cycles.

If you find yourself a constant captive of your charger, utilize the following tips to extend battery life on your Galaxy S7.

  • Disable the “Always On Display” feature: Thanks to the Always On Display feature, the Galaxy S7 never needs to be “woken up” to view the time or notifications. While Samsung claims that Always On Display’s battery consumption is typically less than 1 percent each hour, the company added that consumption might vary depending on the type of content being shown on the display. To turn off “Always On Display”, go to “Settings”> “Display”> “Always On Display”. Then toggle the switch to off.
  • Turn off Smart Stay: Smart Stay enables the front-facing camera on your Galaxy S7 to sense when you are looking at the phone. When activated, the screen remains on regardless of the selected timeout settings. To turn off Smart Stay, select “Settings”> “Display”> “Smart Stay”. Then toggle the switch to “Off”.
  • Switch display settings to dark colors: The Galaxy S7 features a Super AMOLED display, which requires significant power to show the color white. Samsung’s AMOLED shows the color black by dimming the light behind said pixels which requires far less power. To save battery power, select darker wallpapers and themes.

If you’ve tried all of the above tips and your battery is still rapidly draining, you may be in need of a Samsung Galaxy S7 battery replacement. For details on battery replacement services and a do-it-yourself guide, continue reading.

Samsung Galaxy S7 Screen Replacement Guide

The last thing that you want to think about when you are in the middle of dealing with your busy life is a cracked or broken Galaxy S7. Our lives are far too fast paced for us to take time out to deal with our phone slipping out of our grip and shattering on the sidewalk, let alone think about how to get it fixed. Thankfully, the experts at CPR have created this handy Samsung Galaxy S7 screen replacement guide to help you stop worrying about your phone and find a solution.

Common Galaxy S7 Screen Problems

While many Samsung phone reviews suggest the Galaxy S7 is one of Samsung’s best smartphones, there are still some common issues with the device’s screen. One slightly irritating common issue is the screen having varying tints across the display. Some areas toward the bottom of the screen may be slightly darker, or other places will have a slight pink, yellow, or green tint.

Another common problem is the screen going totally black and becoming unresponsive to touch. While some of the buttons may work and lights may come on, the screen stays black and will not turn back on without a restart.

Frozen Galaxy S7 Screen

Sometimes, your Galaxy S7’s screen may freeze and become unresponsive. A frozen screen could be due to a high volume of apps being open all at once, a non-mobile friendly web page having too much on it, an infected app being downloaded onto the phone, a malfunctioning screen, a cracked screen, or a variety of other things. Whatever the cause, having a frozen screen is a major annoyance but we can give you some solutions to fix it.

Frequently, a frozen screen simply calls for a soft reboot of your Samsung Galaxy S7. To do this, simply press down the power button and the volume down button at the same time and hold until the phone vibrates, turns off, and reboots. This usually takes about 7 to 8 seconds.

If this doesn’t work or if you have a cracked screen, it may be time for a professional to evaluate your device to see if you need a screen replacement for you Galaxy S7.

Black Galaxy S7 Screen

Galaxy S7 users have actually reported multiple cases where the phone has started to reboot like normal, and then the screen has gone completely black. Some of the lights may function, and the sound may still work, but the screen remains black and totally unresponsive. While it is not entirely clear why this happens, a lot of the blame has been attributed to software malfunctions, but it is possible that other issues are the cause of the ‘black screen of death.’ There are, fortunately, two different things to try that can fix the problem.

You can reboot the phone in recovery mode by powering the Galaxy S7 off, pressing and holding down the power button and volume down button, waiting for the Android System Recovery screen, use the volume buttons to select “wipe cache partition,” and then the phone will reboot.

If that doesn’t work, you can try a factory reset. This will wipe all of your data and restore your S7 to factory settings, so this should be your last resort. You activate the factory reset by turning off the device, holding down the power button and the volume down button, using the volume keys to navigate the Android System Recovery screen, selecting “Wipe data/factory reset,” and confirming. Then your phone should reboot normally.

If the cache wipe does not work and you don’t want to wipe the phone, it may be time to bring your phone to a professional for evaluation.

Cracked Galaxy S7 Screen

While frozen screens and black screens have workarounds, cracked or shattered screens usually require a more concrete fix. Accidents happen but cracked and shattered screens can be dangerous to carry around and use. Additionally, the inner workings of your phone can sometimes be damaged as a result of the cracked screen. If you have a cracked Galaxy S7 screen, replacement is your best options. This way the screen can be fully replaced so you don’t risk glass in your fingers and more damage to the device.

Samsung Galaxy S7 Screen Replacement Cost
