iPhone & Android Battery Replacement — Same Day
A dying battery should not mean a new phone. We replace iPhone and Android batteries quickly and affordably — most swaps done in under an hour with a full 90-day warranty.
Lithium-ion batteries degrade over time. After 300 to 500 charge cycles, most phone batteries hold significantly less charge than when new — leading to shorter battery life, unexpected shutdowns, and sluggish performance. A battery replacement is often the most cost-effective way to extend the life of a phone you already love.
At Sarge's Cellular, we replace batteries for iPhone, Samsung, Google Pixel, and most other popular Android devices. We use quality replacement cells that meet or exceed original specifications. Every battery replacement comes with a 90-day warranty.
Walk in to our Valparaiso or Navarre location — no appointment needed. Most battery swaps are completed in 30 to 45 minutes.

Frequently Asked Questions
How do I know if my battery needs replacing?
On iPhone, go to Settings > Battery > Battery Health & Charging. If your maximum capacity is below 80%, replacement is recommended. On Android, we can run a free diagnostic in-store.
Will replacing my battery fix slow performance?
Often yes. iPhones with degraded batteries may throttle CPU performance to prevent unexpected shutdowns. A new battery typically restores full performance.
How long does a battery replacement take?
Most battery replacements are completed in 30 to 45 minutes.
Is my data safe during a battery replacement?
Yes. Battery replacement does not affect your stored data.
What happens to my old battery?
We dispose of old batteries responsibly. Lithium-ion batteries require special handling — never throw them in regular trash.
Does a new battery come with a warranty?
Yes. Every battery replacement includes our 90-day warranty on the part and labor.
