Xiaomi Redmi 4A Battery Replacement - CAT 3120mAh (BN30)

If your Xiaomi Redmi 4A is experiencing reduced battery life after daily use, you're not alone. After a year or so of daily use, the original battery starts showing its age - you've probably noticed it doesn't last like it used to. This CAT 3120mAh BN30 replacement brings your phone back to how it performed when new. No more battery anxiety halfway through the day.

This battery includes protection against overcharging, overheating, and short circuits. It's CE certified, which matters especially for Xiaomi Redmi 4A's standard smartphone features that can put extra strain on cheaper batteries. You won't deal with swelling or the safety issues that come with uncertified replacements.

With Xiaomi Redmi 4A's IPS LCD screen and MediaTek Helio G35, you're looking at about 6 hours of mixed use - scrolling social media, messaging, watching videos, taking photos. That's similar to what you got when your Xiaomi Redmi 4A was new, before the battery started losing capacity.

The BN30 connector fits Xiaomi Redmi 4A's power system correctly, so you'll get accurate battery percentage readings - no more random jumps or unexpected shutdowns at 20%. It works properly with Xiaomi Redmi 4A's standard smartphone features too, maintaining stable power throughout the day.

The cells are rated for 500+ charges - that's roughly 18 months to two years of daily charging. Budget batteries using recycled cells? They typically start failing around 8-10 months. The math matters when you're looking at total cost.

Installation is moderately tricky. Xiaomi Redmi 4A's back panel is glued down, so you'll need to heat it up and carefully pry it off, then disconnect the battery connector. Takes about half an hour if you know what you're doing. Professional installation is probably worth it if you're not comfortable opening up phones - there are some delicate cables inside Xiaomi Redmi 4A that can be damaged if you're not careful.

Why Batteries Fail

Battery drain speeds up because of internal resistance. As cells age, chemical reactions build up resistance inside, which forces Xiaomi Redmi 4A's system to pull more power to maintain voltage. That's why your battery drains faster even when you're doing the same things you've always done. A fresh 3120mAh battery with low internal resistance fixes this - normal discharge rates return.

Common Questions

Will this fit my Xiaomi Redmi 4A if I bought it from [local shop/imported/different carrier]?

Yes - all Xiaomi Redmi 4A versions use the same BN30 battery. You can double-check by looking at your current battery (need to pop the back panel off). The model number is printed right on it. Physical size and connections are identical across all Xiaomi Redmi 4A variants.

Can I install this myself or should I pay someone?

Xiaomi Redmi 4A's back panel is glued down, so you'll need heat and pry tools to remove it carefully. Then disconnect the battery connector and swap in the new one. Takes about half an hour. If you've never opened a phone before, professional installation is probably smarter - there are some ribbon cables that are easy to damage.

How many hours will I actually get?

On Xiaomi Redmi 4A with its IPS LCD screen and MediaTek Helio G35: light use (messaging, email) gets you about 8 hours. Normal mix of apps and video? Around 6 hours. Heavy gaming or GPS? About 4 hours. Roughly what Xiaomi Redmi 4A managed when new.

Is this the same quality as official service center batteries?

CAT meets international manufacturing standards and CE certification. Commercial grade that meets Xiaomi Redmi 4A's specs. Official parts might have manufacturer branding, but performance is equivalent for daily use. We source from certified manufacturers, not gray-market suppliers.

Why not just buy the cheapest battery?

Cheap batteries (usually 40-60% less) typically use recycled or Grade B cells with inflated capacity claims. They fail in under a year, so you're buying twice. This lasts closer to two years, which actually costs less annually. Plus cheap batteries risk damaging Xiaomi Redmi 4A through voltage issues or connector problems - repairs cost way more than saving a few hundred rupees upfront.

If you're tired of reduced battery life after daily use and constant charging, this 3120mAh BN30 replacement fixes it. CAT quality means you get genuine specs and CE safety certification - not the inflated claims you see from random marketplace sellers. Your Xiaomi Redmi 4A will last through the day again.
