A bug, now fixed, that had caused unexpected battery drain in some Android smartphones, delayed some over-the-air rollouts of Android 5.0 (Lollipop).
Google wouldn't comment officially on reports of the bug or its fix, or on a release timeline. However, a source told Computerworld today that Google had earlier noted that its Nexus devices running Android would get the final, public release of Lollipop sometime in November. That timeframe remains in place.
Several reports, including one from ZDNet, said the Lollipop rollout was due to take place this past Monday. That date has now been pushed back to Nov. 12, with the delay apparently stemming from fixes to the power-sapping bug.
Trevor Johns, a Google engineer for the Android Open Source Project, wrote on Wednesday on a publicly-available Android Developer Preview discussion board that there was indeed a "significant" battery usage problem for Nexus 5 smartphone users running Android 5.0 when Wi-Fi was enabled.
Later in the day, in another discussion thread, Johns reported the "issue has been fixed in the latest builds, and this issue is now considered resolved."
Johns, however, didn't disclose any official Lollipop release date and declined to offer any details in an email to Computerworld.
Various reports going back to Tuesday indicated that Lollipop was indeed rolling out to a select group of Android smartphones and tablets.
Both the new Nexus 6 and Nexus 9 have 5.0 pre-loaded on them, but older devices will be receiving updates, including Nexus 4, Nexus 5, Nexus 7 and Nexus 10, as well as Google Play Edition devices such as the Moto G and HTC One M8.
Android 5.0 features the new Material Design interface, with flat design elements and bold colors It also, ironically, comes with a battery saver feature that gives a user 90 minutes of use in emergencies.
