Yes, you can customize 5G settings on both Android and iPhone devices to prioritize battery life over data speed[3][2].
iPhone:
* 5G Auto: Enable Smart Data mode to allow your iPhone to automatically switch between 5G and LTE based on usage to save battery life. When 5G speeds donât provide a noticeably better experience, your iPhone automatically switches to LTE[7]. To access this setting, go to Settings \> Cellular \> Cellular Data Options or Settings \> Mobile Data \> Mobile Data Options, then tap Voice & Data**[7].
* LTE: You can also choose to use only the LTE network even when 5G is available to further extend battery life[7].
* Data Mode: Set the Data Mode to Standard to limit data usage on 5G, which can help improve battery life[2]. To do this, go to Settings \> Mobile Data \> Mobile Data Options and tap Data Mode**[2].
Android:
* Adaptive Battery: Turn on Adaptive Battery to optimize battery consumption by learning your usage habits and prioritizing the apps and services you use the most[2]. To enable it, go to Settings \> Battery and device care \> Battery \> More battery settings and toggle on Adaptive battery**[2].
* Optimize Battery Usage (Samsung): On Samsung phones, use the Device care feature to optimize battery usage by closing unused apps and preventing them from running in the background[2]. Go to Settings \> Battery and device care and tap Optimize now**[2]. You can also enable the Auto Optimization feature in the same menu[2].
* 5G Selection: If your network provider allows it, you can disable 5G in settings. If not, the "Samsung Band Selection" app can prioritize preferred bands and disable 5G[5]. To find this setting, navigate to Connections > Wi-Fi > 3 Dots (Upper Right) > Advanced**[5].
When your phone canât get a strong 5G signal, it constantly searches for a better one, causing the battery to drain faster[2].
