Xiaomi Poco M4 5G Battery Replacement - King Power 5000mAh (BN5H)

If your Xiaomi Poco M4 5G is 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 King Power 5000mAh BN5H replacement brings your phone back to how it performed when new. No more battery anxiety halfway through the day.

Safety-wise, this has you covered. Built-in protections stop it from overcharging or overheating - particularly important given Xiaomi Poco M4 5G's standard smartphone features. CE certification means it meets safety standards, something budget batteries often skip to cut costs.

With Xiaomi Poco M4 5G's IPS LCD screen and MediaTek Dimensity 700 5G, you're looking at about 7 hours of mixed use - scrolling social media, messaging, watching videos, taking photos. That's similar to what you got when your Xiaomi Poco M4 5G was new, before the battery started losing capacity.

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 Poco M4 5G'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 Poco M4 5G that can be damaged if you're not careful.

The BN5H connector fits Xiaomi Poco M4 5G'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 Poco M4 5G's standard smartphone features too, maintaining stable power throughout the day.

Why Batteries Fail

Battery drain speeds up because of internal resistance. As cells age, chemical reactions build up resistance inside, which forces Xiaomi Poco M4 5G'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 5000mAh battery with low internal resistance fixes this - normal discharge rates return.

Common Questions

How do I know this actually has 5000mAh 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 4000mAh). Generic sellers don't make guarantees because they know their ratings are inflated.

Can I install this myself or should I pay someone?

Xiaomi Poco M4 5G'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.

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 full charge cycles (about a year to year and a half), capacity drops noticeably. That's when you start seeing reduced battery life after daily use and needing multiple charges per day.

Will this fit my Xiaomi Poco M4 5G if I bought it from [local shop/imported/different carrier]?

Yes - all Xiaomi Poco M4 5G versions use the same BN5H 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 Poco M4 5G variants.

How many hours will I actually get?

On Xiaomi Poco M4 5G with its IPS LCD screen and MediaTek Dimensity 700 5G: light use (messaging, email) gets you about 8 hours. Normal mix of apps and video? Around 7 hours. Heavy gaming or GPS? About 5 hours. Roughly what Xiaomi Poco M4 5G managed when new.
