Removable Phone Batteries: Comeback or Not?

Removable phone batteries are making a limited but real comeback, driven by EU regulations and consumer demand, though they are not yet the industry standard. This article explains the shift, what it means for you, and how to choose a phone with a user-replaceable battery.

Why Were Removable Batteries Abandoned?

For over a decade, most flagship smartphones have sealed-in batteries. Manufacturers favored this design for several reasons:

• Thinner devices: A fixed battery can be shaped to fill every millimeter of the chassis, allowing slimmer designs.
• Water resistance: Sealed backs make it easier to achieve IP67 or IP68 ratings without complex gaskets.
• Build quality: Unibody construction feels more premium and reduces flex and creaking.
• Faster charging: Fixed batteries can be engineered for higher charge rates with better thermal management.
• Planned obsolescence: Critics argue that sealed batteries force upgrades when battery health declines, though manufacturers deny this.

Apple, Samsung, and Google all moved to sealed designs by the mid-2010s, and the trend spread to mid-range and budget phones. The result: users had to visit service centers or replace the entire phone when the battery wore out.

What Changed? The EU Regulation and Consumer Pressure

The turning point came in 2023 when the European Union adopted Regulation 2023/1542, which requires that by 2027, all portable batteries in devices sold in the EU be removable and replaceable by the end-user. This applies to phones, tablets, and other electronics. Manufacturers must design products so that a user with ordinary tools (or no tools) can remove and replace the battery without damaging the device.

While the regulation is EU-specific, global manufacturers rarely make separate hardware for different regions, so the change is likely to affect phones worldwide. Already, several brands have responded:

• Samsung introduced the Galaxy XCover 7 Pro (2024), a rugged phone with a user-replaceable battery.
• HMD (the company behind Nokia-branded phones) launched the Nokia G22 in 2023, designed for easy battery replacement with a simple toolkit.
• Fairphone has always offered user-swappable batteries, and its Fairphone 5 (2023) continues that tradition.
• Motorola and Nothing have explored modular designs, though not all have removable batteries.

These are mostly mid-range or rugged devices, not flagships. But the trend is clear: the industry is moving back toward repairability.

How Does a Removable Battery Work Today?

Modern removable batteries are not like the old plastic-backed phones where you popped off the cover and slid out a pack. Today’s designs vary:

• Tool-free: Some phones (like the Nokia G22) have a SIM-ejector tool that releases the back cover, and the battery lifts out with a pull tab.
• Simple tools: Others require a small screwdriver to remove the back panel or a tray, then the battery can be disconnected and removed.
• Modular: Fairphone uses a modular design where the battery is one of several swappable modules, accessible after removing the back cover.

In all cases, the battery is a separate unit with a connector, not soldered to the motherboard. This makes replacement a 5-minute task rather than a professional repair.

Pros and Cons of Removable Batteries

Here’s a balanced look at what you gain and lose with a removable battery:

• Pros:
  • Instant battery swap: Carry a spare battery and never worry about charging.
  • Longer lifespan: Replace a degraded battery for a few dollars instead of buying a new phone.
  • Repairability: Easier to fix other components if the battery is not glued in.
  • No downtime: No need to send your phone away for a battery replacement.
• Cons:
  • Thicker and heavier: Removable batteries need a protective enclosure, adding bulk.
  • Lower water resistance: Sealed phones can achieve IP68; removable-back phones often settle for IP52 or no rating.
  • Less design freedom: Manufacturers cannot use the battery as a structural element.
  • Potential for poor third-party batteries: Users may buy low-quality replacements that are unsafe or underperform.

How to Choose a Phone with a Removable Battery

If you want a phone with a user-replaceable battery, consider these factors:

• Check the spec sheet: Look for “user-replaceable battery” or “removable battery” in the official specifications. Don’t rely on reviews alone.
• Consider the tool requirement: Some phones need a screwdriver; others are tool-free. Decide what you’re comfortable with.
• Battery availability: Check if the manufacturer sells official replacement batteries and at what price.
• Water resistance trade-off: If you need IP68, a removable battery phone may not exist. Decide which is more important.
• Software support: A repairable phone is only as good as its software updates. Look for phones with at least 3 years of OS updates.

Common Misconceptions and Problems

Misconception: Removable batteries are unsafe. In reality, modern lithium-ion batteries are safe if they meet standards. The risk comes from third-party batteries without proper protection circuits. Stick to official or certified replacements.

Misconception: Removable batteries mean you can’t have fast charging. Fast charging depends on the battery’s internal resistance and charging circuitry, not whether it’s removable. The Nokia G22 supports 20W charging, which is decent.

Common problem: Battery connectors wear out. Repeated removal can stress the connector. However, modern connectors are rated for hundreds of cycles, and most users swap batteries rarely.

Common problem: The back cover cracks. Removing the back cover repeatedly can weaken plastic clips. Use the proper tools and follow the manufacturer’s instructions.

Comparison: Removable vs. Sealed Battery Phones

Feature	Removable	Sealed
Battery replacement	User, minutes	Service center, days
Water resistance	Usually IP52 or less	IP67/IP68 common
Thickness	Thicker (8-10mm)	Thinner (7-8mm)
Spare battery option	Yes	No
Repairability score	High	Low to medium
Typical price	Mid-range	Flagship and mid-range

Cost and Safety Considerations

Replacing a removable battery costs roughly $20-$50 for an official part, compared to $50-$100 for a professional replacement of a sealed battery. However, the real cost saving is in avoiding a new phone. A battery replacement can extend a phone’s life by 2-3 years.

Safety tips:

• Only use batteries that meet the manufacturer’s specifications (voltage, capacity, connector).
• Do not puncture, bend, or expose the battery to heat.
• If a battery swells, stop using it and replace it immediately.
• Dispose of old batteries at designated recycling points.

Frequently Asked Questions

Will the iPhone ever have a removable battery?

Apple has not announced any plan to make iPhone batteries user-replaceable. However, the EU regulation applies to all devices sold in the EU, so Apple will need to comply by 2027. It’s possible they will design a tool-removable battery, but it may not be as easy as popping the back off.

Does a removable battery affect water resistance?

Yes, generally. A removable back panel requires seals and gaskets, which are harder to make perfectly watertight. Most removable-battery phones have no water resistance rating or only IP52 (splash resistant). If you need IP68, you’ll likely have a sealed battery.

Can I replace the battery myself without breaking the phone?

Yes, if you follow the manufacturer’s instructions. Most phones with removable batteries are designed for user replacement, with pull tabs or simple screws. Watch a video guide for your specific model to avoid damaging clips or connectors.

Are third-party replacement batteries safe?

Only if they are certified and match the original specifications. Look for batteries with CE, UL, or other safety marks. Avoid very cheap batteries from unknown brands, as they may lack protection circuits and could overheat.

Will removable batteries make phones thicker?

Yes, slightly. The battery needs a protective housing and a removable back, which adds about 1-2mm. That’s why flagship phones with ultra-thin designs are unlikely to adopt them.

Is the EU regulation the only reason for the comeback?

No. Consumer pressure for repairability, the right-to-repair movement, and environmental concerns also play a role. The EU regulation is a major catalyst, but brands like Fairphone have shown there is demand for repairable phones.
