Pixel and Galaxy Battery Drain: What Actually Works When Updates Don’t

The uncomfortable truth: the “fixes” aren’t fixing everything

Ongoing Pixel and Galaxy battery drain refers to severe power loss, overheating, or slow charging that continues even after installing official software updates that manufacturers claim should resolve these problems, forcing users to rely on their own smartphone battery drain solutions and Android battery troubleshooting instead of clear, effective guidance from Google or Samsung.

Here’s the key takeaway: you cannot assume that installing the latest patch will rescue your battery. Google’s July update (build CP2A.260705.006) is supposed to fix a long‑running Pixel 9 and Pixel 10 idle drain bug, yet some owners say their phones still tank from full to empty while sitting in a pocket. Meanwhile, a July 2026 One UI 8.5 update is linked to heavy Galaxy S24 battery drain, especially on S24 and S25 models. This isn’t an isolated glitch; it is a pattern across brands that points to systemic software problems rather than a single defective handset. Until manufacturers deliver reliable fixes, users need to take control with practical, sometimes blunt, workarounds.

Why Pixel batteries keep dying after Google’s “fixed” label

Google says its July patch eliminates a “severe idle drain” bug for most Pixel 9 and Pixel 10 phones, and that Pixel 9a and 8a owners will receive their solution in a September update. On paper, the story ends there. In reality, plenty of users report that the Pixel battery drain fix did not change much, or anything, on their phones.

Deep Doze mode appears to be the villain. Instead of letting the phone sleep, it keeps the CPU awake, so the device burns through power even when idle. Some affected users say their battery lasts only a few hours, but switching to airplane mode drastically improves endurance. That is not normal behavior; it is a sign that radios and background processes are mismanaged. The uncomfortable part: it is unclear why some Pixels suffer and others don’t, and Pixel 7 owners report similar drain without any promised fix yet. If you bought a Pixel 10 advertised at USD 799 (approx. RM3,680) and now reduced to USD 599 (approx. RM2,760), you are right to feel frustrated when your flagship can’t last a day.

Galaxy S24 and S25: when a security update wrecks your battery

On the Samsung side, Galaxy S24 Ultra and S25 Ultra owners describe a trifecta of problems after the July 2026 security update: severe battery drain, overheating, and slower charging. Some people wake up to find 60% of their battery gone overnight, with no heavy use to blame. That is more than annoying; it makes premium phones unreliable.

Here’s the twist: Samsung has yet to officially acknowledge these battery issues, and no clear cause is confirmed. Users suspect the combination of One UI 8.5 and WhatsApp is at fault. After the update, WhatsApp can get stuck in an encrypted backup loop, running constantly in the background and pushing phones to heat up while idling. Reports say the glitch mainly affects Galaxy S24 and S25 models, though other devices may be touched too. In other words, Galaxy S24 battery drain is not your imagination; it is a side effect of software decisions you never asked for.

Practical Pixel workarounds: stabilise your battery today

If your Pixel still bleeds battery after the July patch, waiting for another monthly update is not a plan; it is a gamble. You need hands‑on Android battery troubleshooting that targets the real culprits: radios and background CPU use. In some cases, users report that switching to airplane mode turns a phone that dies in a few hours into one that lasts far longer. That is a giant hint.

1. Test airplane mode overnight. If your idle drain collapses, the issue is likely tied to cellular or Wi‑Fi activity rather than the screen or apps.
2. Disable 5G temporarily and lock the phone to LTE to reduce modem power spikes when signal is weak.
3. In Settings > Battery, identify apps at the top of the usage list and restrict or uninstall anything that should not be waking the phone frequently.
4. Turn off always‑on display and aggressive background syncing for email, social, and cloud backup apps to reduce Deep Doze wake‑ups.
5. If the July update worsened your Pixel battery drain, avoid further beta or preview releases; stick to stable builds until Google ships a proven fix.

Galaxy survival guide: taming WhatsApp and bad updates

For Galaxy S24 and S25 owners, the evidence points toward software, not hardware, so replacing the phone is usually overkill. The most realistic smartphone battery drain solutions start with limiting the damage from One UI 8.5 and misbehaving apps. Some reports suggest WhatsApp backups get stuck after the July update, creating constant background activity that drains power and heats the phone.

1. Check if the July 2026 One UI 8.5 update is installed; if not, consider delaying it until a later patch addresses battery issues.
2. If you already updated, turn off WhatsApp cloud backups or sign out temporarily to stop the suspected encrypted backup loop.
3. Use WhatsApp’s web version in desktop mode from your browser as a temporary workaround to avoid the native app’s drain.
4. Monitor battery usage in Settings; if WhatsApp or another app dominates, restrict its background activity or uninstall it until the issue is fixed.
5. In the short term, keep the phone out of cases that trap heat and avoid charging while gaming, since overheating is part of this bug’s profile.

Across both Pixel and Galaxy, one of the few universal tips worth quoting is this: “Whether you use a Google Pixel or Samsung Galaxy, the easiest solutions are to either avoid the July 2026 update or, if it’s already installed, to wait for either the usual August release or an interim patch.” Until Google and Samsung earn back trust with fixes that stay fixed, your best defense is careful updating and aggressive control over apps that misbehave.
