Galaxy S5 battery life actually is amazingly good.
Most tests and benchmarks indicated Galaxy S5 battery life actually is really in the top tier among the flagship smartphones. For example, PhoneArena reported a far better battery life of Galaxy S5 than other flagship smartphones: HTC One (M8), LG G2, Nexus 5.
In our daily normal usage, most Galaxy S5 owners can get 4+ hour screen time. So, the Galaxy S5 battery life is sufficient for all-day usage for most S5 owners.
Samsung in recent years apparently invested a lot on technologies of saving battery on Android phones. In addition to normal battery saving options, you may also turn on ultra power saving mode when you are not able to connect to a charger for a prolonged period.
Why I have Galaxy S5 battery life problems?
However, some Galaxy S5 owners reported battery drain problems on Galaxy S5.
There are many possible reasons of Galaxy S5 battery life problems. Here are some of the commonly-encountered ones:
- Some poorly written apps are running in the background and refuse to sleep. You can go to Settings–Battery to find out such apps easily.
- Some system processes are in weird state. Normally, the system processes can manage themselves properly. But in certain situations, a few may fail to do so. If you find most of the battery is consumed by Android System, it means it is time to reboot the phone.
- Mobile network signal is poor.
- WiFi is always on. You may check Settings–WiFi–Menu key (3 vertical dots, or hardware menu button)–Advanced -Keep WiFi on during sleep. You probably should set it to never (and turn off mobile data as well) or only when plugged in.
- Frequent use of hotspot (sharing mobile data connection with other devices) or WiFi Direct. These two are battery killers.
- Your Galaxy S5 is running some third-party task manager or battery juice defender or similar apps. Most of these apps will only do the opposite: they will cause Galaxy S5 battery life problem, instead of solving the battery life problem.
- Your Galaxy S5 is running some anti-virus apps. Such apps are not necessary if you get apps only from reliable sources, e.g. Google Play store or Amazon appstore for Android.
- You didn’t maintain and charge your Galaxy S5 battery properly.
