Overview
- Users reported faster idle battery loss, device warming and slower charging after July system updates for high‑end Pixel and Samsung phones.
- Google says it found two system processes that repeatedly prevented Pixels from entering Deep‑Doze low‑power sleep and has added a correction to the July build CP2A.260705.006.
- The July Pixel patch reached Pixel 9 and Pixel 10 series models and the Pixel 10a while Google says Pixel 8a and 9a will get the fix with the September quarterly update.
- Samsung has not published a technical response and community tests point to a stuck WhatsApp encrypted‑backup process as a likely cause, with users reporting that aborting or disabling the backup restores normal battery behavior.
- Because Android relies on Deep‑Doze for low idle consumption, staged rollouts and continued user reports mean owners should watch idle drain after updates and report persistent problems to vendor channels while awaiting broader patches.
