Xiaomi Mi A1 Battery Replacement - CAT 3080mAh (BN31)

If your Xiaomi Mi A1 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 3080mAh BN31 replacement brings your phone back to how it performed when new. No more battery anxiety halfway through the day.

The battery includes protection against overcharging, overheating, and short circuits. It's CE certified, which matters especially for Xiaomi Mi A1'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 Mi A1's IPS LCD screen and Qualcomm Snapdragon 625, 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 Mi A1 was new, before the battery started losing capacity.

The BN31 connector fits Xiaomi Mi A1'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 Mi A1'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 Mi A1'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 Mi A1 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 Mi A1'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 3080mAh battery with low internal resistance fixes this - normal discharge rates return.

Common Questions

How do I know this actually has 3080mAh capacity?

The capacity is marked right on the battery cell. We provide testing docs, and dastyab.pk guarantees at least 80% of rated capacity (which would be 2464mAh). Generic sellers don't make guarantees because they know their ratings are inflated.

Will this fit my Xiaomi Mi A1 if I bought it from [local shop/imported/different carrier]?

Yes - all Xiaomi Mi A1 versions use the same BN31 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 Mi A1 variants.

Can I install this myself or should I pay someone?

Xiaomi Mi A1'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. If you haven't opened a phone before, professional installation is probably smarter - there are some ribbon cables that are easy to damage.

Why do phone batteries die in the first place?

Three main reasons: heat (from charging and heavy use), deep discharges (running it down to zero repeatedly), and just time - cells degrade even sitting unused. After 300-400 charge cycles (roughly a year to 18 months), capacity drops noticeably. That's when you start seeing reduced battery life after daily use and needing multiple charges per day.

Can this battery swell up or catch fire like cheap ones?

CAT batteries are CE certified with built-in protections - overcharge cutoff, short circuit protection, thermal limits. The batteries you hear about in news stories are usually uncertified cells with fake capacity ratings that stress the cells beyond safe limits. This has proper protection circuits, same as original batteries.

Dastyab.pk sources CAT batteries from certified manufacturers with actual quality control. Every BN31 battery gets tested - voltage, capacity, connector integrity - before it ships. We stand behind the 3080mAh rating. If you want your Xiaomi Mi A1 working like it used to, this is the reliable option. Same-day dispatch across Pakistan.
