Many people are surprised to find out their LG phone battery cannot be removed. This change caused confusion for some users who were used to older models with removable batteries.
Yes, most recent LG smartphones have non-removable batteries. This design shift began several years ago and follows a global trend in the mobile industry.
Phones used to come with removable backs and replaceable batteries. Now, that's rare. This article explains why LG made the switch, which models have sealed batteries, and whether it's still possible to change them.
Which LG models feature non-removable batteries?
Many customers still ask if LG phones can have their batteries replaced. Some older models allowed it, but that’s no longer common.
Almost all LG smartphones released after 2016 feature non-removable batteries, including the LG V series, G series, and Velvet series.
Today, LG’s smartphone lineup almost entirely consists of sealed battery designs. Below is a breakdown of models:
LG Phones with Non-Removable Batteries
| Model Name | Battery Type | Release Year |
|---|---|---|
| LG V60 ThinQ | Non-removable | 2020 |
| LG G8 ThinQ | Non-removable | 2019 |
| LG Velvet | Non-removable | 2020 |
| LG Wing | Non-removable | 2020 |
| LG K92 | Non-removable | 2020 |
| LG Stylo 6 | Non-removable | 2020 |
LG Phones with Removable Batteries (Legacy)
| Model Name | Battery Type | Release Year |
|---|---|---|
| LG G4 | Removable | 2015 |
| LG V10 | Removable | 2015 |
| LG K10 | Removable | 2016 |
| LG X Power | Removable | 2016 |
The shift began in 2016. That was when LG slowly began sealing the battery compartment on its flagship phones. This followed the general smartphone trend started by Apple and Samsung.
Why did LG shift to sealed battery designs?
Back when phones had removable batteries, changing them was quick. People liked that. But times changed.
LG adopted sealed batteries to support thinner designs, water resistance, and better battery safety.
Three Key Reasons Behind the Shift
1. Sleeker and Stronger Build
Users want thinner phones with large screens. Removable battery covers limited how slim a phone could be. By sealing the battery inside, LG engineers had more room to optimize space.
2. Water and Dust Resistance
When a phone is sealed, it’s easier to protect it from water and dust. This is important for phones with IP ratings. LG G6, for example, had an IP68 rating — which was only possible with a sealed back.
3. Battery Safety
Older batteries could be removed and replaced incorrectly. That created safety risks. A sealed battery, when installed properly at the factory, lowers the chance of loose connections or thermal runaway issues.
Timeline of LG's Battery Evolution
| Year | Battery Type Trend | Example Model | Key Feature Shift |
|---|---|---|---|
| 2014 | Removable | LG G3 | Plastic back, hot-swap |
| 2016 | Mixed | LG G5 | Modular design |
| 2017 | Non-removable | LG G6 | IP68 Water Resistant |
| 2018 | Non-removable | LG V40 ThinQ | Slim profile, glass back |
Most competitors had already moved away from removable batteries. LG eventually followed that path to remain competitive.
Are non-removable batteries harder to replace?
This is a big question for repair technicians and DIY users. Many assume “non-removable” means “not replaceable.” That’s not true — but it is harder.
Yes, non-removable batteries are more difficult to replace. You need tools, patience, and some experience.
What Makes Replacement Harder?
- Adhesive and Sealing: Most LG phones with non-removable batteries are sealed using strong adhesive. You need to heat the back cover before prying it open.
- Delicate Components: Inside, components like fingerprint sensors and flex cables are easy to damage.
- Special Tools Required: Unlike old phones where you could pop the back open with your nail, newer LG phones need plastic pry tools, suction cups, and heating pads.
Common Replacement Steps (For Repair Technicians)
- Power off the device.
- Use a heat gun or pad to soften the adhesive around the back panel.
- Pry the back cover off carefully.
- Disconnect the battery connector.
- Remove the old battery using plastic tools.
- Install the new battery and reassemble the phone.
These steps aren’t difficult for a trained technician. But for most users, it's safer to ask a repair shop.
Is It Still Worth Replacing?
Yes — especially if the phone is working well and just the battery is weak. A battery replacement can give a phone 1-2 more years of life.
Repair shops often keep LG battery models in stock. For B2B clients, it’s smart to source tested LG batteries in bulk. They often come with tools included and pre-applied adhesive for easier installs.
What are the pros of non-removable LG batteries?
Non-removable doesn’t always mean worse. In fact, sealed batteries have many upsides — both for users and manufacturers.
Non-removable batteries help LG phones stay safer, look better, and last longer without mechanical wear.
Benefits of Sealed Batteries
1. Improved Safety
Sealed batteries are installed professionally and less likely to be damaged. This reduces overheating, short circuits, and swelling.
2. Sleek, Modern Design
Phones look better without seams or back covers. LG phones like the Velvet or Wing have slim glass backs that feel premium.
3. Water Resistance
IP-rated LG phones rely on sealed designs. A removable battery cover would make waterproofing nearly impossible.
4. Fewer User Errors
Some people used to install third-party batteries that didn’t meet quality standards. This caused performance and safety problems. Sealed designs avoid that.
5. Stronger Frame Structure
Phones with sealed backs are more rigid. This means they bend less in pockets and can survive drops better.
Should Businesses Worry?
If you’re in mobile repair or wholesale, the shift to non-removable batteries changes how you stock parts and offer services. You’ll need:
- Tested battery units compatible with newer LG models
- Tools for safe removal and reinstallation
- Instruction sheets for repair technicians or customers
For wholesalers, providing kits that include tools and adhesive can be a smart value-add. Many clients appreciate getting everything they need in one pack.
Conclusion
Most modern LG smartphones use non-removable batteries. This design supports better safety, slimmer shapes, and waterproof features. While harder to replace, trained repair shops and wholesalers can still service them easily with the right tools and parts.
