Does Keeping Your Phone Plugged In All the Time Damage Your Battery? We Asked Apple, Samsung and Google

Consider this the final word from Apple, Google and Samsung on charging past 100%.

That gut feeling that tells you to sprint to unplug your phone the second it hits 100%? It’s time to let it go. That advice is ancient history. Modern smartphones are smart enough to cut off the power once they’re fully charged, so leaving your iPhone or Android plugged in overnight isn’t going to destroy the battery.

But let’s be clear: Just because it’s safe doesn’t mean it’s optimal. While you can’t technically «overcharge» the battery, keeping a lithium-ion cell pinned at 100% creates voltage stress, and the heat generated from sitting on a charger is the real, silent enemy of longevity.

It’s not about immediate damage; it’s about how fast your battery ages over time. Understanding the difference between what won’t break your phone and what will actually help it last is key. Here’s the truth about your charging habits.

The science behind battery wear

Battery health isn’t just about how many times you charge your phone. It’s about how it manages voltage, temperature and maintenance. Lithium-ion batteries age fastest when they’re exposed to extreme levels: 0% and 100%.

Keeping them near full charge for long stretches puts additional voltage stress on the cathode and electrolyte. That’s why many devices use «trickle charging» or temporarily pause at 100%, topping up only when needed.

Still, the biggest threat isn’t overcharging — it’s heat. When your phone is plugged in and running demanding apps, it produces heat that accelerates chemical wear inside the battery. If you’re gaming, streaming or charging on a hot day, that extra warmth does far more harm than leaving the cable plugged in overnight.

Apple’s take

Apple’s battery guide describes lithium-ion batteries as «consumable components» that naturally lose capacity over time. To slow that decline, iPhones use Optimized Battery Charging, which learns your daily routine and pauses charging at about 80% until just before you typically unplug, reducing time spent at high voltage.

Apple also advises keeping devices between 0 to 35 degrees Celsius (32 to 95 degrees Fahrenheit) and removing certain cases while charging to improve heat dissipation. You can read more on Apple’s official battery support page.

What Samsung (and other Android makers) do

Samsung offers a similar feature called Battery Protect, found in One UI’s battery and device care settings. When enabled, it caps charging at 85%, which helps reduce stress during long charging sessions.

Other Android makers like Google, OnePlus and Xiaomi include comparable options — often called Adaptive Charging, Optimized Charging or Battery Care — that dynamically slow power delivery or limit charge based on your habits. These systems make it safe to leave your phone plugged in for extended periods without fear of overcharging.

When constant charging can hurt

Even with these safeguards, some conditions can accelerate battery wear. As mentioned before, the most common culprit is high temperature. Even for a short period of time, leaving your phone charging in direct sunlight, in a car or under a pillow can push temperatures into unsafe zones.

Heavy use while charging, like gaming or 4K video editing, can also cause temperature spikes that degrade the battery faster. And cheap, uncertified cables or adapters may deliver unstable current that stresses cells. If your battery is already several years old, it’s naturally more sensitive to this kind of strain.

How to charge smarter

You don’t need to overhaul your habits but a few tweaks can help your battery age gracefully.

Start by turning on your phone’s built-in optimization tools: Optimized Battery Charging on iPhones, Battery Protect on Samsung devices and Adaptive Charging on Google Pixels. These systems learn your routine and adjust charging speed so your phone isn’t sitting at 100% all night.

Keep your phone cool while charging. According to Apple, phone batteries perform best between 62 and 72 degrees Fahrenheit (16 to 22 degrees Celsius). If your phone feels hot, remove its case or move it to a better-ventilated or shaded spot. Avoid tossing it under a pillow or too close to other electronics, like your laptop, and skip wireless chargers that trap heat overnight.

Use quality chargers and cables from your phone’s manufacturer or trusted brands. Those cheap «fast-charge» kits you find online often deliver inconsistent current, which can cause long-term issues.

Finally, don’t obsess over topping off. It’s perfectly fine to plug in your phone during the day for short bursts. Lithium-ion batteries actually prefer frequent, shallow charges rather than deep, full cycles. You don’t need to keep it between 20% and 80% all the time, but just avoid extremes when possible.

The bottom line

Keeping your phone plugged in overnight or on your desk all day won’t destroy its battery. That’s a leftover myth from a different era of tech. Modern phones are smart enough to protect themselves, and features like Optimized Battery Charging or Battery Protect do most of the heavy lifting for you.

Still, no battery lasts forever. The best way to slow the inevitable is to manage heat, use quality chargers and let your phone’s software do its job. Think of it less as «babying» your battery and more as charging with intention. A few mindful habits today can keep your phone running strong for years.

Google Could Revive Last Year’s Bright Pink Color for the Pixel 10a

Google’s upcoming Pixel 10a is expected to launch in February with some new colors, including one popular ask.

The Google Pixel 9a is one of Google’s most affordable Pixel phones, and it includes one of the most frequently requested colors — bright pink. With the Google Pixel 10a rumored to launch in February, we’re already getting a hint at the colors the new model will come in.

According to Roland Quandt, a regular mobile leaker on Bluesky, the Google Pixel is expected to be offered in obsidian (black), berry (pink), fog (light gray), and lavender colors. However, it’s the berry hue that is intriguing customers.

A representative for Google did not immediately respond to a request for comment.

«I always love to see phones come in vibrant colors, and it’s especially welcome in more budget-friendly options,» said Abrar Al-Heeti, senior technology reporter at CNET. «Yes, we tend to slap a case on our phones anyway, but just knowing your phone touts a bold color can make it feel like more of a statement piece, rather than a bland piece of tech.»

Pink is one of the most requested color options for the Pixel phones. CNET sister site Mashable loved the color when it debuted on the Pixel 9. Phone rivals like Apple and Samsung are usually expected to offer a pink color option in their flagship and midrange phone lineups, so it’s not surprising to see the berry color on the Pixel 10a.

«I’ll say that Google loves having Pixel phones in pink,» said Patrick Holland, CNET managing editor. «The Pixel 9 and 9a come in peony (a bright, bold pink) and the 9 Pro in rose quartz (a more muted pink). The Pixel 10 series lacks any pinkish hues.»

Quandt also says that the Pixel 10a will have 128GB and 256GB storage models, and will launch in mid-February. That’s earlier than expected compared with the Pixel 9a, which was revealed in mid-March 2025 for a launch on April 10. In terms of specifications, we expect the Pixel 10a to be a modest upgrade compared with previous generations. According to leaks, the Pixel 10 is unlikely to feature a newer Tensor G5 chip, and it’s likely to retain the same overall design as the Pixel 9a.

One leaker, Mystic Leaks on Telegram, expressed disappointment and revealed additional specs, including the absence of a telephoto lens, UFS 3.1 storage, a Tensor G4 chip, a 2,000-nit display and no Magic Cue, which is Google’s AI feature for the Pixel 10.
