Samsung tablets have sealed batteries you cannot remove yourself
Most Samsung tablets sold in the last ten years have non-removable batteries that are glued or soldered inside the case. Unlike older phones and tablets where you could pop off the back cover and swap the battery, Samsung now builds the battery as a permanent part of the device. This means you cannot remove it at home without damaging the tablet.
If your tablet's battery is failing, swelling, or no longer holds a charge, you have two real options: send it to Samsung for a battery replacement, or take it to an authorized repair shop. Both routes involve opening the case, which requires tools and skill to do without breaking the screen or internal components.
The reason Samsung sealed the battery is water resistance. A removable battery door means a seam where water can enter. By gluing the battery inside, Samsung made tablets that survive spills and splashes better. The trade-off is that battery replacement becomes a professional job instead of something you do yourself.
Key Takeaways
- Samsung tablets have batteries glued or soldered inside the case and cannot be removed without professional tools and informed.
- Attempting to remove the battery yourself risks cracking the screen, damaging the motherboard, and voiding any remaining warranty.
- Samsung's official repair service will replace the battery, though the cost and turnaround time vary by model and your location.
- Authorized third-party repair shops often complete battery replacements faster and sometimes cheaper than Samsung, but verify they use genuine parts.
- If your tablet is still under warranty and the battery is failing, contact Samsung first—they may cover the replacement at no cost.
When a Samsung tablet battery needs replacement
A battery that no longer holds a charge for more than an hour or two, even after a full charge cycle, has reached the end of its useful life. Lithium batteries degrade over time—typically after 500 to 1,000 full charge cycles, which usually means two to four years of normal use. If your tablet is older than that and the battery drains quickly, replacement is the practical solution.
A swollen or bulging battery is a safety issue and needs when ready attention. If you notice the back of the tablet is warped, the screen is lifting away from the frame, or the tablet feels hot during normal use, stop using it and do not attempt to open it yourself. A swollen battery can catch fire. Contact Samsung support or take the tablet to a repair shop right away.
If your tablet is still under warranty—usually one year from purchase—and the battery is failing, Samsung will often replace it for free. Check your purchase receipt or contact Samsung support with your model number and serial number to confirm your warranty status before paying for a repair.
Sending your tablet to Samsung for battery replacement
Samsung's official repair service is the safest route if you want to be certain the work is done correctly and the battery is genuine. Visit Samsung's support website for your region and search for "repair" or "service center." You will find a list of authorized service centers near you, or you can arrange a mail-in repair.
For mail-in repair, Samsung will provide a prepaid shipping label. You pack the tablet, drop it off, and Samsung receives it, diagnoses the battery, replaces it, and ships it back. The whole process typically takes two to three weeks, though it varies by how busy the service center is. You will pay a service fee—usually between $100 and $200 depending on the model—unless the tablet is still under warranty.
Before you send it in, back up any files you want to keep. Samsung may perform a factory reset as part of the repair process, which erases all data on the device. Also note the model number (found in Settings > About Tablet) so you can reference it when you contact Samsung.
Using an authorized third-party repair shop
Authorized Samsung repair partners and independent repair shops that specialize in tablets often complete battery replacements in one to three days instead of weeks. Many are local businesses you can visit in person, which means you can watch the work happen and pick up the tablet the same day or the next morning.
The cost is often lower than Samsung's official service—sometimes $50 to $150 instead of $100 to $200—but this varies widely by location and shop. Before you commit, ask whether they use genuine Samsung batteries or third-party replacements. A genuine battery will last longer and is less likely to cause problems. Also ask whether they offer a warranty on the repair itself, typically 30 to 90 days.
Check reviews on Google Maps or Yelp before you choose a shop. Look for shops that have been in business for at least a few years and have mostly positive reviews mentioning battery replacement specifically. Avoid shops that advertise "we can open any device" without mentioning experience with tablets—phone repair shops do not always have the right tools for tablets.
What happens if you try to open the tablet yourself
Opening a Samsung tablet requires a heat gun or heat mat to soften the adhesive holding the back panel, a plastic pry tool to separate the panel without cracking it, and small screwdrivers to remove the screws holding the battery connector. Even with the right tools, the risk of breaking the screen or damaging the motherboard is high if you have not done this before.
The screen is glued to the frame and sits directly behind the back panel. If you pry too hard or in the wrong spot, the screen cracks. A cracked screen costs $150 to $300 to replace, which is often more than the battery replacement itself. The motherboard sits near the battery connector, and if you accidentally pull a ribbon cable or knock a component loose, the tablet may not power on again.
Opening the tablet also voids any remaining manufacturer warranty. If something goes wrong during the repair, Samsung will not cover it. For most people, the time, tools, and risk are not worth the small amount of money saved by doing it yourself.
How to extend your current battery's life
If your tablet's battery is aging but still usable, you can slow its decline by changing how you charge and use it. Lithium batteries last longer when they stay between 20 and 80 percent charge. If you leave your tablet plugged in at 100 percent for hours every day, the battery ages faster. Unplug it once it reaches full charge, and try not to let it drop below 20 percent regularly.
High heat speeds up battery degradation. Keep your tablet out of direct sunlight and away from heaters or hot surfaces. If the tablet gets warm during use, close apps running in the background and lower the screen brightness. A tablet that runs cool will have a battery that lasts longer.
Reduce screen brightness and turn off features you do not use constantly—Bluetooth, GPS, and location services all draw power. In Settings, look for Battery Saver or Power Saving Mode and turn it on. These steps will not stop the battery from aging, but they will buy you extra months before replacement becomes necessary.
