Every smartphone owner runs into battery trouble at some point. You may charge your phone overnight, only to see the battery drop quickly the next morning. It can leave you second-guessing whether your charger is working properly or if the phone needs to be replaced. 

Before jumping to conclusions, there’s a better first step: check the battery health. This simple check can explain why your phone doesn’t last as long as it used to, especially if you’re using apps that drain power quickly. Whether you’re watching videos, using GPS all day, or placing bets on mobile casino platforms, your battery performance plays a key role. 

Why Battery Health Deserves Attention 

Batteries don’t keep their original strength forever. Over time, they lose the ability to hold a full charge. That’s normal, but it becomes a problem when the drop in capacity starts to affect daily use. 

Imagine playing a fast-paced card game, switching between apps, or even playing with £1 deposit on a slot app while out and about. To take full advantage of such a great casino bonus, you’ll need a reliable phone battery. If your battery decides to shut the phone off unexpectedly, you could lose more than just a game round. Good battery health supports smoother experiences, fewer interruptions, and better performance overall. 

A strong battery also supports smoother video calls, fast loading times, and the kind of speed modern phones promise. When the battery struggles, the phone slows down, heats up, or lags. 

Check Battery Health on an iPhone 

Apple users can check battery condition easily through built-in settings. 

  • Go to settings 
  • Tap battery 
  • Select battery health & charging 
     

There, you’ll see a percentage labelled Maximum Capacity. This tells you how much charge the battery can still hold, compared to when it was brand new. If it shows 90% or above, your battery is in good shape. A reading near or under 80% means the battery has aged, and you might notice shorter screen time or slower app response. 

Apple also adds a message in this section if the phone has adjusted performance to match the battery’s condition. If you see a note about service, it means the phone detects that the battery no longer performs well enough. 

Check Battery Health on an Android 

Checking battery condition on Android depends on the phone model. Different brands handle this in their own way, but there are still a few easy methods that work for most. 

Method 1: Through System Settings 

  1. Open settings 
  1. Find battery 
  1. Tap battery usage

 

This view shows how the phone has used power over time. You’ll see a breakdown of which apps use the most battery, how long the screen stays on, and in some models, temperature and charging history. While it doesn’t show exact battery health, it gives clues. 

 

Phones by brands like Xiaomi or OnePlus may offer more detailed battery stats in their system menus, including charging cycles and battery wear. 

Method 2: Using a Hidden Code 

Android has secret codes that bring up diagnostic menus. 

 

  1. Open the phone app 
  1. Type *#*#4636#*##

This may open a testing menu. If it works, look for “Battery Information.” You might find stats on temperature, status, voltage, and health. This menu doesn’t appear on all models. Samsung phones, for example, block this code. 

Method 3: Samsung’s Built-In Tool 

Samsung phones come with a pre-installed app called Samsung Members. 

 

  1. Open the app 
  1. Tap get help 
  1. Choose interactive checks 
  1. Tap battery
     

This tool tells you if the battery runs well or if there’s a problem. It also checks other functions like memory and screen performance. 

Method 4: Third-Party Apps 

When built-in tools don’t offer enough detail, apps from Google Play can fill the gap. A few trustworthy ones include: 

  • AccuBattery shows capacity, charging speed, and wear 
  • Battery by MacroPinch displays temperature, voltage, and charge cycles
  • CPU-Z is known for hardware info, with battery details included
     

These apps don’t change your battery health, but they help you understand it better. 

Signs That Point to a Worn Battery 

Sometimes the phone starts acting differently. It might feel warm even when you’re not using it. You may notice sudden drops in battery percentage. These signs suggest the battery doesn’t perform the way it used to. 

 

Here are some other clues: 

 

  • The battery drains fast, even with light use 
  • The phone shuts off before reaching 1% 
  • Charging takes much longer than normal 
  • Apps reload often or crash unexpectedly 
  • The screen dims without you adjusting it
     

A battery nearing the end of its life shows one or more of these patterns. Even if the phone still turns on, these small changes add up. 

When to Check and What to Watch 

You don’t need to check battery health daily. Every few months works well for most users. If you notice problems, like short battery life or overheating, then it’s time to check. 

Also, consider checking before and after a software update. Major updates can increase battery usage, especially if your phone is already two or three years old. 

If you plan to sell or trade in your phone, knowing the battery condition gives you a better idea of its current value. 

How to Keep Your Battery Healthy 

Once you’ve checked the battery, you may want to keep it strong for as long as possible. Here are some useful habits: 

 

  • Unplug the phone once it reaches about 80% 
  • Avoid letting the battery drop below 20% too often 
  • Don’t use the phone while charging during heavy tasks 
  • Keep the phone out of hot places, like parked cars or sunlit windows 
  • Use certified chargers from trusted brands 
  • Keep background apps closed when not in use
     

These steps won’t stop the battery from ageing, but they slow down the process and help the phone stay reliable longer. 

Conclusion 

Battery health affects everything you do on your phone. From casual scrolling to placing bets, the battery powers it all. You don’t need tools, tech skills, or new gadgets to check on it. Both Apple and Android phones give you ways to find out how the battery performs. 

 

Once you know where you stand, you can take action. Whether it’s a replacement, a new habit, or a better charging routine, small changes keep your phone useful for longer. 

 

Your battery may sit inside the phone, out of sight. But its condition has a real impact. Stay on top of it, and your phone will keep up with everything you need it to do.
