Google Says the Pixel Battery Drain Bug Is Fixed. Samsung Owners Are Now Living Through Their Own Version of It.
July has been an unusually rough month for battery life across the Android ecosystem, and the irony is hard to miss. Google spent months chasing down a stubborn idle battery drain bug on Pixel phones and finally marked it “Fixed” this week — only for users to keep reporting the exact same symptom. At almost the same moment, a completely separate group of Samsung Galaxy owners started flooding community forums with complaints about battery drain and overheating, triggered by Samsung’s own July software update. Two different companies, two different root causes, and the same underlying complaint landing in the same news cycle.
The Pixel Side: “Fixed,” According to Google — Not According to Everyone Else
The Pixel battery drain saga has been running since spring. The bug first emerged following Google’s March 2026 software update and became significantly more visible after the April release, when hundreds of users began reporting their phones were burning through battery far faster than normal while sitting completely idle — in some cases, cutting battery life roughly in half.
The technical culprit, according to Google’s own public Issue Tracker, was labeled “Severe Idle Drain: kepler_spi_irq_handler & gnss_ipc Suspend Aborts” — in plain terms, the affected phones were failing to properly enter Deep Doze, the low-power state Android uses to conserve battery when a device isn’t being actively used. Instead, the device’s CPU stayed effectively half-awake, chewing through charge for no reason.
This week, Google closed out the bug report with a formal update: “Google has fixed the ‘Severe Idle Drain’ issue. A fix has been merged in the July MPR (CP2A.260705.006) release for Pixel 9 Pro XL / Pixel 9 / Pixel 10 Pro XL / Pixel 10 / Pixel 10a.” Owners of the Pixel 8a and Pixel 9a will have to wait until September’s Quarterly Platform Release for the same fix, and Google hasn’t said whether Pixel 7 or Pixel 8 devices — which were also reported as affected — will get any fix at all.
Here’s the part that undercuts the good news: reaction to Google’s fix announcement has been decidedly mixed. Some Pixel owners report genuine improvement since installing the update. Others, posting directly on Google’s own support threads, say the drain is exactly as bad as before. Adding to the confusion, Google’s official July release notes don’t mention any battery drain fix at all — meaning the only place this fix is documented is a single Issue Tracker comment, not the company’s actual public changelog. That gap makes it genuinely difficult to independently confirm what changed, or whether the fix is comprehensive versus a partial mitigation that only helps under certain conditions.
The Samsung Side: A Different Bug, a Different Update, the Same Complaint
Running in parallel — and easy to conflate with the Pixel story if you’re only skimming headlines — is a distinct problem affecting Samsung Galaxy devices. A growing number of users on Samsung’s own Community Forums have reported intense battery drain and overheating following Samsung’s July 2026 software update, built on One UI 8.5. The complaints cluster heavily around the Galaxy S25 and S24 series, particularly the Ultra models, though reports have also surfaced from Galaxy Z Fold 6 and Z Fold 7 owners.
One especially detailed Galaxy S25 Ultra report captures the pattern well: dramatically higher battery usage despite less active screen time than usual — the same “draining while doing nothing” symptom Pixel owners have been describing for months, just on different hardware entirely.
Multiple reports point to a specific, identifiable trigger: WhatsApp getting stuck mid-backup following installation of Samsung’s OTA update. One user on Samsung’s community forums described their Galaxy Z Fold 7 dropping from roughly 80% to 10–15% battery within five to six hours, even in standby, despite battery health still reading 100% — a strong signal the problem is software-driven rather than hardware degradation. Several affected users report the fix, at least temporarily, is simply turning off WhatsApp’s automatic backup feature — which stopped the drain but obviously isn’t something Samsung or Meta should expect users to have to discover and troubleshoot themselves.
Two Separate Bugs, One Very Bad Week for Android Battery Life
It’s worth being precise here rather than overstating the connection: these are two distinct issues with two different root causes, on two different manufacturers’ software. The Pixel drain traces back to a suspend/wake handling failure in Google’s own platform code. The Samsung drain appears tied to WhatsApp’s backup process interacting badly with One UI 8.5’s latest changes. Neither company’s update is directly causing the other’s bug.
What makes this genuinely notable — and why it’s worth covering together rather than as two unrelated footnotes — is the timing and the symmetry. Google spent months publicly working toward a battery-drain fix, finally declared victory, and is now facing skepticism that the fix actually works. In the very same week, Samsung’s update meant for routine improvements introduced a fresh battery drain problem of its own, on some of its most popular current devices. For anyone tracking Android software quality across the two biggest manufacturers, July 2026 isn’t shaping up as a strong month for either company’s QA process.
What to Do If You’re Affected
If you own an eligible Pixel (9, 9 Pro, 9 Pro XL, 10, 10 Pro, 10 Pro XL, or 10a) and are still seeing excessive idle drain after installing the July update, know that Google’s official position is that it’s fixed — so if the problem persists, it’s worth adding your report directly to Google’s Issue Tracker thread rather than assuming it will resolve itself, since the rollout is still staged across regions and some complaints may reflect devices that haven’t received the actual fix yet.
If you own an affected Galaxy device — particularly a Galaxy S24, S25, or Z Fold model — and you’re seeing drain or overheating after the One UI 8.5 update, the most immediately actionable step reported by affected users is disabling WhatsApp’s automatic backup temporarily to see if it resolves the symptom, while continuing to update all apps through both the Google Play Store and Galaxy Store and monitoring Samsung’s community forums for an official fix.
