Why Does Android Randomly Restart?

A common question Android users may ask is “Why does my Android randomly restart itself?” At one point or another, every Android device I’ve owned has had this problem. There are a few common reasons your Android might restart on its own. Let’s take a look at them and see if we can fix it.

Loose Battery

Of course, this problem only occurs on devices with a removable battery. My Droid 1 and Samsung Galaxy S4 were notorious for suddenly restarting. Sometimes they would shut off and never turn back on. It turned out that in both cases, the battery was coming a bit loose. Just a slight jab at the device would quickly unseat, then re-seat the battery.

The most common reason for this is the rear cover has become slightly bent and is no longer holding the battery into place. Another reason is the gold battery connectors are bent out of shape. Over time, the connectors get worn down kind of the same way the Nintendo Entertainment System’s cartridge connectors did.

There are two ways to tackle a problem with a loose battery:

1. Purchase some mounting tape, then affix a small piece to an area of the rear cover so that it holds the battery into place better.
   
2. Turn the device off, remove the rear case and unseat the battery. Locate the battery connector pins. If possible, use a small screw driver to pry the connectors into a position where they will make better contact with the battery.
   

Overheating

Many Android devices are designed to shut off if they become too hot. If you have your device out on a 100 degree day while trying to use 4G, GPS, and a screen set to the brightest setting, it might restart itself or even shut down. Try to take it easy and maybe disable features you don’t need.

Overheating shutdowns shouldn’t be a regular problem though. If your device is overheating regularly, contact the retailer or manufacturer about it.

Bad Apps

You may have an app running in the background that is causing the Android to randomly restart. When an app is the suspected cause, try the following, preferably in the order listed:

1. Uninstall apps you don’t necessarily need. This goes especially for any apps that control sound, ringtones, wallpaper, have fancy widgets, or uses the GPS.
2. Ensure all apps are on the latest version. Upgrade everything you have from the Play Store by going to Menu > Settings > My Apps.
3. Uninstall apps that run in the background. From a fresh restart, go to Settings > More… > Applications > Running. If you see anything listed you can live without, uninstall it. If you cannot uninstall it, freeze the app if possible.

Corrupted System Software

Sometimes the Android system software gets corrupted. If you are using a custom Android ROM, try a different version of the ROM or another type of ROM altogether. If you’re not using a custom ROM, your only option may be to try a factory reset of the device. Beware though, a factory reset will erase data from your device. On most Android devices, you can perform a factory reset by going to Settings > Backup & reset > Reset device.

Defective Hardware

If everything above has been tried and your Android is still randomly restarting itself, you may just have a bad device. Contact the retailer or manufacturer about the problem. You may not have that option if you have a custom Android ROM installed. In that case, you may want to take your question to the maker of your particular ROM
