S7 Battery Life Is Shorter After Software Update

Problem: My phone had a system update in the past few days, and the battery life is significantly shorter now.  I am not using my phone any more than prior to the update. I also have not downloaded any new apps. I routinely use the battery saver and put apps to sleep.  Before the update, I could start the day at 100% battery and it would still be at about 35% at 10pm. Since the update, I have to charge it by about 6pm.


Solution: When a phone gets a new software update, depending on what update it is getting, several new features and improvements will be introduced to the device. This usually means that the phone will be configuring some of its data causing the processor to work more often. This is only temporary and will use up some battery life.

If the issue occurs for several days then the next step that you will want to do is to check if any of your apps have an update available. An outdated app might be causing this problem as it is not optimized to work with the new software version. Go to the Google Play Store app on your phone then check if any apps have updates available.

There’s also a possibility that some old software data has not been removed during the update process. This will cause a conflict with the new software version resulting in this problem. The best thing to do in this case is to backup your phone data then do a factory reset.

If the above steps fails to fix the problem then it’s possible that the battery might already be faulty. You will need to bring the phone to a service center and have this battery replaced.

S7 Does Not Turn On

Problem: I have a S7  that suddenly got stuck in a boot loop without me having some anything (adb, flashing, etc) to cause this sudden behavior.. M. I could enter into recovery utilizing the button combo sequence so I attempted a factory reset several times having seemingly see no effect on the device . It was still stuck on boot logo screen. So, I decided to download the firmware file. I got everything downloaded that I needed (official firmware, adb and USB drivers, platform tools, etc). However, now I can’t even get the phone to enter recover, boot loop, or anything. The only sign of life is that, every once in a while, a little light flashes from front. Additionally, my PC does indicate a device has been connected with the standard audible “ding”, but that’s it. The screen still does not light up, flash, flicker, vibrate, or anything else. This phone is already a replacement for my original one. The warranty period has run its course from the time of my original purchase . The current phone doesn’t have one scratch or crack on the digitizer nor the underlying lcd display. What are my options?  FYI, the original carrier was Verizon, but I recently had the phone officially unlocked by Verizon and am/was using my new carrier, Metro PCS. Any thoughts on my dilemma are greatly appreciated. I’m no rookie when it comes to flashing, repairing, dismantling, assembling, etc of all brands of phones both Android and Apple. With that in mind, by all means, any and all suggestions to fix are welcome.

Solution: You won’t be able to do anything with the phone unless it turns on which is why the first thing you will need to do is to make sure that the battery has sufficient charge. To do this just follow the troubleshooting steps listed below.

  • Clean the charging port of the phone using a can of compressed air.
  • Charge the phone for at least 20 minutes using a wall charger.
  • If the phone does not charge then try using a different charging cord and wall charger. You should also try charging the phone from a computer USB port.

Once the phone has charged then try turning it on. If it is still stuck in the boot logo then try flashing the phone with its updated firmware file.

If the above steps fails to fix the problem then this might already be caused by a faulty hardware component. You will need to have this checked at a service center.

S7 Stuck In Boot Logo

Problem: I have a Galaxy S7 phone and gave it to my husband as I got an upgrade. I’m with Three.com and my husband is with o2. I put his sim in and it all powered up ok and I sent a test text, all ok. Tried to load a gmail email address and got a authentication error. So decided to do a factory reset to start afresh. Then my real trouble started. When it rebooted the S7 logo and Samsung logo came on then it had the white screen with T Mobile and there it stayed and I couldn’t get it to go any further.I tried restarting several times, but still the same. So this time I tried a master reset, by pressing up volume, power and home keys and then up volume and home and then selected wipe factory reset. But still when it rebooted it had the white T Mobile screen and cannot get into the normal user screen. What have I done wrong and how can I put it right? The phone worked perfectly up until then. By the way I picked lollipop version, but I have no idea what it is and I couldn’t proceed without that field being completed. Thanks

Solution: If a factory reset does not fix the problem then you should consider flashing the phone with its updated stock firmware file using Odin. You can get this file from the Sammobile website which is also where you can get the instructions on how to flash your phone.

If the issue persists then this could already be caused by a faulty hardware component in which case you will need to bring the phone to a service center and have it  checked.
