Luckily, the Battery optimiser setting allows you to stop apps from sapping energy when the phone isn’t in use. If you’re experiencing overheating even when not using or charging your phone, it could be down to a particular app. It’s enabled by default so chances are, if you haven’t turned it off already, this could be the source of your overheating woes. To disable quick charging, go to Settings > Battery and turn Fast Cable Charging off. Either way, turning these settings off can reduce the uncomfortable warmth that can build up during charging. While the Exynos models of the S7 and S7 Edge use Samsung’s Adaptive Fast Charging technology, the Snapdragon 820 models use Qualcomm’s Quick Charge 2.0 tech. If, however, the handset is heating up without your intervention, it could all be down to the fast-charge setting. In this case it could simply be down to the fact that you’re using the phone while it’s charging. Some users are reporting that their handset is getting too hot when charging. If you find that your Galaxy S7 is overheating, there are a number of ways to tackle the problem. The other advice, if you suffer from this issue, is to invest in a good chunky case, which typically puts an extra few millimetres between your fingers and the screen. Unfortunately, there’s no fix for this at present, other than that old iPhone 4 ‘Deathgrip’ advice: hold it differently. It can also cause issues when gripping the phone a certain way whilst trying to take a picture, with the shutter button proving unresponsive, or even when trying to type out a message on the keyboard. This can be a particular problem for the Galaxy S7 Edge, for obvious reasons.
We’ve seen some Galaxy S7 users complaining that the display is simply too sensitive, and that the palm-rejection feature isn’t doing its job of filtering out incidental presses around the edges of the display. Once your phone restarts, the power and volume buttons should be responsive again. I question whether I will have the same issues with the new device - if not immediately, then soon after.While the power and volume buttons might appear unresponsive, holding the power and home buttons together should still reset the Galaxy S7. According to a representative, I would probably get a S8 Active to replace my S7 Active. Unfortunately, I will probably file an insurance claim.
I feel I shouldn't have to sacrifice my usage due to what I feel is a software problem. The phone worked fine prior to a system update. While I can probably extend the life (changing the power settings, brightness, turning off wifi, Bluetooth, etc.), I shouldn't have to.
I have tried several things to resolve the battery issue as well (which, incidentally, started right after a system update also). However, the battery life puts me a huge limitation.
I tried cleaning the charging port with alcohol/Qtip, wiping the system cache, clearing the USB data/cache, tried several different chargers/cables, blowing into the port, computer dust cleaner, etc. I have tried all the suggested methods to try and resolve it.
It's been several days since I first started getting the message (which occurred right after a system update).
