Get your phone fixed without leaving your doorstep
Phone battery issues are one of the top complaints we hear from customers—and it’s no surprise. As we rely more and more on our smartphones every day, the battery gets pushed harder than ever. From constant app use to endless charging cycles, most batteries just can’t keep up forever.
Modern smartphones use lithium-ion batteries, which are designed to be lightweight, fast-charging, and long-lasting—but even they have limits. After 500 full charge cycles (roughly 1–2 years of use), most start to decline.
In this post, we’ll break down the most common phone battery issues, what causes them, and what you can do to fix or prevent them.

One of the most frustrating phone battery issues is watching your percentage drop fast—even when you’re not using your phone.
If your phone gets too hot to touch, it’s a sign something’s wrong—and it can lead to battery damage or even fire risks.
Another confusing battery issue is when your phone dies—even though it says 30% or 50% battery was left.
If your phone shuts off the second you unplug it, the battery isn’t doing its job.
Slow or no charging is a clear red flag when it comes to phone battery issues.
If your battery level goes from 80% to 20% in seconds—or jumps back up out of nowhere—your battery is struggling.
Phone battery issues usually come from a few key habits or conditions—and most of them are preventable once you know what to watch for.
Every phone battery has a lifespan. After about 500 full charge cycles, most lithium-ion batteries start to degrade. That means your phone may still work, but the battery won’t hold a charge like it used to. If your phone is 2+ years old and the battery drains fast, age is likely the culprit.
Heat and cold both mess with battery performance. Cold weather can slow your phone down or cause sudden shutdowns, while high heat can permanently damage the battery’s cells. Leaving your phone in a hot car or using it under the sun can speed up battery failure.
Leaving your phone plugged in overnight every night can wear out the battery faster. While modern phones stop charging at 100%, the battery still gets mini “top-offs” all night long, which adds to its wear.
Cheap or off-brand charging cables might save a few bucks, but they can damage the charging port and strain your battery. Always use high-quality or original equipment when possible.
Streaming, gaming, GPS, or even TikTok for hours drains power fast—and heats up your phone in the process. Heavy usage doesn’t just cause battery drain; it contributes to long-term battery wear.
If your screen looks like it’s lifting or your phone feels thicker, you may have a swollen battery—a serious issue that means gas is building up inside the battery. This is dangerous and needs immediate replacement.
If you’re having phone battery issues, checking the battery’s health is a good first step. Both iPhone and Android make this relatively easy.
Go to Settings → Battery → Battery Health & Charging. Here, you’ll see your Maximum Capacity—this tells you how your battery compares to when it was new. If it's below 80%, you’ll likely need a replacement soon.
Battery health tools vary by brand. Some Android phones include it under Settings → Battery → Battery Usage, or you can use dial codes like *#*#4636#*#* to access detailed info. There are also trusted apps like AccuBattery that can help.
If your battery health is under 80%, or you’re seeing issues like swelling, random shutdowns, or major battery drops—it’s time for a replacement. Most of the time, it’s a quick and affordable fix.
Phone battery issues don’t always mean it’s time for a replacement—sometimes, a few smart habits can make a big difference. Here’s what you can do right now to fix or prevent common problems.
Apps like Instagram, Gmail, and Facebook constantly update in the background, draining your battery without you even opening them. Disable background app refresh in your settings to give your battery a break.
Every smartphone has a low power or battery saver mode. Use it when your battery’s running low or if you notice faster drain than usual. It limits background activity and keeps you going longer.
Don’t leave your phone in the car, on a sunny windowsill, or next to hot electronics. Heat speeds up battery wear and can even cause swelling or damage.
Cheap or frayed cables are a common cause of slow charging and overheating. Always use quality cables and bricks—especially ones that match your phone’s power requirements.
Outdated operating systems can cause glitches, battery drain, and inaccurate battery readings. Always install software updates when available—they often include performance and battery life improvements.
Just like a laptop, your phone benefits from a regular reboot. Restarting clears out temporary bugs and memory issues that could be contributing to battery problems.
Sometimes phone battery issues go beyond quick fixes. If you're noticing any of these red flags, it's time to consider a replacement.
This is a safety hazard. A swollen battery puts pressure on the screen and internal components. If your phone looks puffed up, stop using it and get it replaced immediately.
If your battery capacity is reading below 80%, it’s no longer working efficiently. You’ll notice shorter battery life and slower performance—both signs it’s time for a swap.
Frequent, random shutdowns or a phone that dies at 30% are major signs your battery is failing. No software fix will help—only a new battery will.
If your phone suddenly can’t last more than a few hours even when you’re barely using it, your battery likely isn’t holding a charge properly anymore.
Trying to fix phone battery issues yourself can go very wrong. Here’s why leaving it to the pros is usually the better move.
Opening a smartphone without the right tools or knowledge can damage internal components—or worse, puncture the battery and cause a fire. Many phones use glue and delicate connectors that aren’t beginner-friendly.
Modern phones are tightly sealed to keep them waterproof. This means replacing the battery involves heating, prying, and specialized tools—especially for models like iPhones and Samsungs.

Phone battery issues come with a lot of questions. Here are some quick answers to the ones we hear most.
Most smartphone batteries are built to last about 2–3 years, or 500 full charge cycles. After that, battery life and performance usually start to decline.
Not necessarily. Fast charging is safe when you’re using the manufacturer’s charger or a trusted, high-quality third-party brand. Overuse of fast charging can create heat, which may accelerate wear over time.
It’s rare, but yes—swollen or damaged batteries can overheat or catch fire, especially if punctured. If your phone is hot, puffed up, or smells burnt, stop using it immediately and get it looked at.
