To check Samsung battery health, open Settings > Battery > Battery information. On most Galaxy phones from the S24 and Z Fold 6 onward, it shows health as a percentage and the cycle count. On older models, open the Samsung Members app, tap Support > Phone diagnostics > Battery status, and you'll get Normal, Weak or Bad. It takes about two minutes.

Battery is usually the first thing a buyer asks about, and it's the easiest thing to check yourself. Knowing your result before you list the phone means no surprises when the buyer opens Settings, and a quote that doesn't change at the door.
Key Takeaways
- Settings > Battery > Battery information shows a percentage and cycle count on newer Galaxy phones.
- Samsung Members gives a simple Normal, Weak or Bad result on almost any Galaxy.
- Normal roughly means 80% or more of the original capacity.
- Dubai heat wears batteries faster, so check even if your phone isn't that old.
- Don't replace the battery just to sell. Get a quote first and compare.
Method 1: Check Battery Health in Settings
This is the quickest way, and it gives you a real number.
- Open Settings.
- Tap Battery.
- Scroll to the bottom and tap Battery information.
- Look at Battery health (a percentage) and Cycle count (how many full charges it has done).
The page also shows the battery's manufacture date and first use date. Take a screenshot. It's the easiest proof you can show a buyer.
Which Galaxy phones show it?
Samsung switches this page on by model, region and software version, and hasn't published a full list. In general:
Galaxy model
Battery information in Settings?
Galaxy S25 series and S26 series
Yes, on One UI 7 or later
Galaxy S24 series, including S24 FE
Usually yes, on One UI 7 or later
Galaxy Z Fold 6, Z Flip 6 and newer
Yes, on recent software
Older Galaxy S and A models
Often missing. Use Samsung Members
Method 2: Check Battery Status in Samsung Members
This works on almost every Galaxy, including older ones and the A series.
- Open the Samsung Members app. It comes pre-installed on most Galaxy phones.
- Tap the Support tab.
- Under Phone diagnostics, tap Get started.
- When the test finishes, tap Battery status.
You'll see one of three results:
Result
What it means
What buyers think
Normal
No performance issues, roughly 80% or more of the original capacity
Fine, no price cut for the battery
Weak
Efficiency has dropped from long use or heat
Expect a lower offer
Bad
Battery life has degraded significantly
Expect a much lower offer, or a battery replacement
The downside: "Normal" covers a wide range, so a phone at 81% and one at 98% both show the same word. If your phone supports Method 1, use that for the real number.
Method 3: Service Codes and Battery Apps
You'll see these suggested online. Here's the honest version:
- Dialer codes (*#0228# or *#9900#): these open hidden service menus. They don't work on every model, carrier-locked phones often block them, and the battery reading is buried in technical logs. Most people don't need them.
- Battery apps like AccuBattery: they estimate health after several days of normal use. Useful as a second opinion, but buyers trust Settings and Samsung Members more.
For selling, a screenshot from Method 1 or 2 is all you need.
What Is a Good Battery Health for a Used Galaxy?
Battery health
What it means
Effect on your offer
90% to 100%
Very good
Helps you get the best price
80% to 89%
Normal wear for one to two years of use
Fair price
70% to 79%
Worn, the phone won't last a full day
Lower offer
Below 70%
Poor, replacement needed soon
Much lower offer
Most batteries are expected to hold around 80% of their capacity after many charge cycles. Below that, the drop in daily use becomes easy to notice, and buyers price that in.
Why Dubai Heat Wears Out Galaxy Batteries Faster
Heat is a battery's worst enemy, and Dubai has plenty of it. A phone left on a car dashboard in summer, charged in a hot car, or used for gaming while it charges ages faster than the same phone in a cooler country. That's why a two-year-old Galaxy in Dubai can show a weaker battery than you'd expect.
If you're keeping the phone a little longer before you sell:
- Turn on Battery protection: Settings > Battery > Battery protection. The Maximum option stops charging at around 80%.
- Don't charge it in a hot car or leave it in direct sun.
- Avoid gaming or video calls while charging.
Should You Replace the Battery Before Selling?
Usually not. A new battery costs money, and the higher offer rarely covers it. If you use a cheap, non-genuine battery, some buyers will mark it down anyway.
It can make sense only if the battery shows Bad, the rest of the phone is in great condition, and you can get it replaced at an authorised Samsung service centre. Even then, get a free quote first and compare the two numbers.
Other Things Buyers Check on a Used Galaxy
Battery is only one part of the price. Before you sell, also check:
- Screen burn-in: open a plain grey image at full brightness and look for faint shapes.
- Cracks and scratches on the screen, back and frame.
- S Pen on Ultra models, and the inner screen and hinge on foldables.
- Samsung and Google accounts: remove them before you reset. Our guide onremoving your Samsung account before selling shows every step.

Frequently Asked Questions
How do I check battery health on my Samsung phone?
Open Settings > Battery and scroll to Battery information. On newer Galaxy phones with One UI 7 or later, it shows battery health as a percentage and the cycle count. If you don't see it, open the Samsung Members app, go to Support > Phone diagnostics and tap Battery status.
What does Normal, Weak or Bad mean in Samsung Members?
Normal means the battery has no performance issues, which roughly matches 80% or more of its original capacity. Weak means efficiency has dropped from long use or heat. Bad means battery life has degraded significantly, and Samsung suggests visiting a service centre.
Why can't I see Battery information in Settings?
Samsung turns this page on by model, region and software version. Older models and some regional builds don't show it. Use the Samsung Members app instead, or check again after your next software update.
What is a good battery health for a used Galaxy?
90% or above is very good. 80% to 89% is normal wear for a phone that's a year or two old. Below 80%, most buyers expect to replace the battery soon and offer less.
Does battery health affect how much I get for my Galaxy?
Yes. It's one of the first things buyers check. A Normal battery helps you get a fair price, while Weak or Bad usually means a lower offer. Tell us your result when you ask for a quote, so the price doesn't change at pickup.
Is the *#0228# code safe to check Samsung battery health?
Dialer codes like *#0228# and *#9900# are service menus. They don't work on every model, especially carrier-locked ones, and the readings are hard to interpret. Settings or Samsung Members are simpler and safer for most people.
Should I replace my Galaxy battery before selling?
Usually not. Replacement costs money and you rarely get it all back in a higher offer. If the battery shows Bad, get a quote first and compare it with the repair cost.
