Samsung tablets are not designed for user battery removal
Most Samsung tablets manufactured in the last decade have non-removable batteries that are permanently sealed inside the device. Unlike older phones and tablets, you cannot pop off the back cover and swap out the battery yourself. The battery is glued to the internal frame and connected directly to the motherboard with solder joints, not straightforward connectors.
If your Samsung tablet's battery is failing, swelling, or no longer holds a charge, you have two practical options: send it to Samsung for a battery replacement, or take it to an authorized repair shop. Attempting to pry open the tablet yourself will damage the screen, frame, and internal components, and will void any remaining warranty.
Key Takeaways
- Samsung tablets have batteries that are glued and soldered inside the device, not user-replaceable like older models.
- Opening a Samsung tablet yourself will crack the screen and damage internal parts, and voids your warranty.
- Samsung's official repair service and authorized repair shops have the tools and parts to replace the battery safely.
- A swollen battery is a safety hazard and should be serviced when ready rather than left in the device.
- Battery replacement typically costs between $80 and $150 depending on the tablet model and repair location.
When you should have the battery replaced
A Samsung tablet battery usually lasts between three and five years of regular use. Signs that replacement is needed include the device shutting down at 20 or 30 percent battery, taking much longer to charge than it used to, or the tablet feeling warm during normal use.
A swollen or bulging battery is a safety issue and requires when ready attention. If you notice the back of the tablet is warped, the screen is lifting away from the frame, or the device feels puffy, stop using it and contact Samsung or a repair shop right away. A swollen battery can catch fire, so do not attempt to open it yourself.
How to contact Samsung for battery replacement
Start by visiting Samsung's support website and entering your tablet's model number. You can find the model number on the back of the tablet (usually printed as "SM-" followed by letters and numbers) or in Settings under About Tablet. Samsung's site will show you service options in your country.
You can mail the tablet to Samsung's repair center, or in some regions you can schedule a pickup. Samsung will diagnose the battery, replace it if needed, and return the tablet to you. The process typically takes one to two weeks plus shipping time. You will need to pay for the service unless the tablet is still under warranty and the battery failure is not due to physical damage or liquid exposure.
Using an authorized repair shop instead
An authorized Samsung repair shop can often replace the battery faster than mailing it to Samsung. Search online for "Samsung authorized repair near me" or check Samsung's official repair locator on their website. Authorized shops have genuine Samsung parts and proper tools, so the repair is covered by Samsung's standards.
Call ahead and ask the cost and turnaround time. Most authorized shops can replace a battery in one to three business days. Costs vary by location and tablet model, but expect to pay $80 to $150 for the battery and labor. Ask whether they offer a warranty on the repair work.
Why you should not open the tablet yourself
Opening a Samsung tablet requires removing the screen first, which is glued on with strong adhesive. Prying it off will almost certainly crack the glass. Once the screen is off, you must disconnect multiple ribbon cables and remove dozens of small screws in the correct order. One mistake breaks the motherboard or other components.
The battery itself is glued down and soldered to the power board. Removing it without the right desoldering equipment will damage the board permanently. Even if you somehow succeed, reassembling the tablet so it is waterproof again is nearly impossible without a heat press and proper sealant. The repair will cost more than having a professional do it, and the tablet may not work correctly afterward.
What to do while waiting for battery service
If your tablet's battery is draining quickly but the device still works, you can extend the time between charges by lowering the screen brightness, closing background apps, and turning off location services and Bluetooth when you are not using them. Go to Settings, then Battery or Device Care, and turn on Battery Saver mode.
Keep the tablet cool while you wait for service. Do not leave it in direct sunlight or in a hot car. If the battery is swollen, do not charge it and do not use it. Store it in a cool, dry place away from flammable materials until you can have it serviced.
Frequently Asked Questions
Can I replace the battery myself if I watch a YouTube video?
No. YouTube repair videos make it look easier than it is, and they do not show the damage that happens off-camera. The screen will almost certainly crack, and you risk damaging the motherboard. The cost of fixing mistakes is higher than paying a professional the first time.
What if my tablet is out of warranty?
Samsung and authorized repair shops will still replace the battery for a fee. The cost does not change based on warranty status. If the tablet is very old, check whether the repair cost is worth keeping the device, since a new budget tablet may cost less than $200.
How long does a Samsung tablet battery last?
Most Samsung tablet batteries are rated for 500 to 1,000 charge cycles, which usually equals three to five years of daily use. A charge cycle is one full discharge from 100 percent to zero, so using 50 percent of the battery and charging it counts as half a cycle.
Is it safe to use a tablet with a failing battery?
A slowly draining battery is safe to use. A swollen battery is not—stop using the tablet when ready and contact a repair shop. A battery that overheats during normal use should also be serviced soon, as overheating can damage other components.
Will replacing the battery erase my data?
No. A battery replacement does not touch the storage where your photos, apps, and files are kept. Your data will be exactly as it was before the repair. Samsung and authorized shops do not erase devices during battery service unless you ask them to.
