JayVii<p>My <a href="https://social.jayvii.de/tags/Fairphone" class="hashtag" rel="nofollow noopener" target="_blank">#Fairphone</a> 4 is draining battery like crazy over the past few months. Surely, I should buy a new battery for it soon (software says, a full charge is around 3350 mAh instead of 3900 mAh it had back in 2021 when I bought it), but this cannot be the only issue here...</p><p>Not using it at all drains around 2-3%/h and simply web browsing or a short YouTube video sometimes drains 30%/h (extrapolating). Sometimes, the device is warm even when I haven't used it for hours. The Energy-consumption settings page lists cellular connection as the top consumer next to display (when using the phone). That is, even when the device sits motionless at a spot with perfect 4G or 5G connectivity. It is only bearable in energy-saving mode (1%/h).</p><p>I've been researching online, and it looks like a bunch of people have that issue. People are speculating it is a non-functional deep-sleep in some circumstances. I wonder if a factory reset (or switch to <a href="https://social.jayvii.de/tags/LineageOS" class="hashtag" rel="nofollow noopener" target="_blank">#LineageOS</a>?) could help.</p><p>Did anyone have similar experience with <a href="https://social.jayvii.de/tags/FP4" class="hashtag" rel="nofollow noopener" target="_blank">#FP4</a> or even other <a href="https://social.jayvii.de/tags/Android" class="hashtag" rel="nofollow noopener" target="_blank">#Android</a> devices?</p><p><a href="https://social.jayvii.de/tags/Fairphone4" class="hashtag" rel="nofollow noopener" target="_blank">#Fairphone4</a> <a href="https://social.jayvii.de/tags/Fairphone5" class="hashtag" rel="nofollow noopener" target="_blank">#Fairphone5</a> <a href="https://social.jayvii.de/tags/FP" class="hashtag" rel="nofollow noopener" target="_blank">#FP</a> <a href="https://social.jayvii.de/tags/eOS" class="hashtag" rel="nofollow noopener" target="_blank">#eOS</a> <a href="https://social.jayvii.de/tags/Smartphone" class="hashtag" rel="nofollow noopener" target="_blank">#Smartphone</a></p>
