When cell towers are damaged or overloaded, phones have to work harder to stay connected, which uses more power. Weak signal, frequent reconnections, and increased activity from the phone’s modem are among the main reasons why the battery may not last long in these conditions.
The biggest factor is weak or unstable signal strength. When phones have difficulty connecting to a cell tower, they increase the transmission power. The power amplifier inside the phone is one of its most power-consuming parts, and it works overtime when the signal is weak.
Researchers have found that signal strength degrades during emergencies when networks are overloaded or damaged, meaning phones use more energy just to stay online.
These networks can become overloaded as people simultaneously call, send messages and use data to contact others. Heavy traffic may cause a slow connection and frequent data transmissions, causing the phone’s radio and processor to remain active for longer periods of time.
Even when it’s not being actively used, the phone’s modem is constantly talking to nearby towers, checking in and syncing. When downloading data, the modem is responsible for 40 percent of the total mobile energy consumption.
When the network is unstable, phones switch between towers or network types to find a better connection. They have to reconnect and resync more often, leading to higher energy usage.
When the network is weak or unstable, the phone has to do more behind the scenes to maintain the connection – such as resending data or performing additional checks. This extra work means the radio and processor are busier than usual, draining the battery even faster.
Reports of GPS interference may also have an impact. People in the UAE have reported GPS systems showing incorrect locations or failing to load. When a device struggles to find an accurate satellite signal, the GPS chip continues to scan and recalculate the location, which keeps the sensor and processor active and consumes more battery.
how to save battery
Simple solutions like lowering screen brightness and shortening screen time-out settings can reduce power consumption. Power saving mode limits background activity and closes unnecessary apps. And reducing the frequency of email and social media syncs for updates saves energy, as frequent syncing keeps the device active even when it’s not being used.
The researchers found that delaying background traffic reduced energy consumption by 23.7 and 21.5 percent under Wi-Fi and 3G, respectively.
When you’re in an area with weak reception, turn off mobile data when not needed and disable Wi-Fi, Bluetooth, and GPS to save energy. All these functions regularly scan for signals in the background.
Keeping device software updated can improve energy efficiency, and using the correct charger and avoiding extreme heat and cold helps maintain long-term battery health. According to Samsung, modern smartphone batteries perform better when not completely discharged, so keeping the battery above about 20 percent charge can help preserve its lifespan.
