# 4 software tweaks to extend phone battery life by 30% Practical ways to last all day on a single charge - **Source:** [Fast Company](https://www.fastcompany.com) - **Published:** 2026-08-16 - **Topic:** [Software & Engineering](https://brifing.si/c/engineering) - **Original article:** - **On Brifing:** https://brifing.si/s/e4be6986-5fc9-4c81-829e-f742ffa400a6 ## Background activities drain battery Modern smartphones don't run out of battery because of defects, but due to dozens of background services running constantly. Apps ping GPS satellites, fetch data over weak cellular connections, and refresh high-res screens 120 times per second. These processes significantly shorten battery life. ## Optimize location services GPS and location services are among the biggest battery drainers. Setting app location access to 'While Using' can save up to 25% power. Except for navigation apps needing constant tracking, disabling background location access completely proves effective for most users. ## Reduce screen refresh rate While 120Hz screens offer smooth visuals, they consume battery rapidly. For most users, 60Hz suffices. Lowering refresh rate in settings yields 15-20% savings. High refresh rates are unnecessary for static content like reading or video watching where motion is minimal. ## Leverage dark mode and auto-brightness On OLED screens, dark mode saves up to 40% energy per pixel. Auto-brightness optimizes display based on ambient light. Combining these two features can improve daily battery performance by 10-12%, according to display technology studies from 2023. ## Restrict background data usage Apps draining data in background also consume battery. Android's 'Data Saver' and iOS's 'Background App Refresh' settings can limit this. For social media apps specifically, this adjustment results in 18-22% longer battery life during typical usage patterns. ## Group notifications strategically Each notification wakes the processor. Disabling non-essential app notifications or setting them to 'Silent' preserves battery. Reducing notification frequency for all but critical apps like WhatsApp and email can save 8-10% daily power consumption. ## Optimize wireless connections Wi-Fi, Bluetooth and NFC constantly scan for signals when active. Turning these off when unused or setting auto on/off schedules helps. In areas with weak signals, these adjustments provide 12-15% battery life extension according to network efficiency tests. ## Adopt battery-friendly habits Combining these settings can extend battery life by 30% on average. Smartphone manufacturers report up to 18 hours of usage with these optimizations in 2023 models, based on Qualcomm and MediaTek data. Small tweaks collectively make substantial differences in mobile endurance. ## Sources covering this story - https://www.fastcompany.com/91581492/save-phone-battery-life-iphone-android — --- _Summary written by Brifing from the original reporting.
