If your phone battery is draining quickly, you’re not alone. It’s one of the most common issues smartphone users face, especially after 1–2 years of usage.
You charge it to 100%.
Within a few hours, it’s down to 40%.
Or worse, it drops from 20% to 5% in minutes.
Let’s break down why this happens, when a battery change is required in an iPhone, and what your options look like.
Why Is Your Phone Battery Draining Fast?
Battery drain isn’t always a battery problem. But often, it is.
Here are the most common reasons.
1. Battery Health Degradation
All smartphone batteries are lithium-ion. Over time, they naturally degrade. After 500–800 charge cycles, battery capacity starts dropping noticeably.
If your iPhone battery health is below 80%, performance and backup will reduce significantly.
2. Background App Activity
Apps running in the background constantly use power. Social media, navigation apps, and gaming apps are heavy consumers.
3. Software Updates
Major iOS updates can temporarily increase battery drain as the system re-indexes data.
4. Overheating
Heat accelerates battery wear. Using your phone while charging or heavy gaming can damage battery cells over time.
5. Charging Habits
Frequent deep discharges (0%) or overnight overheating while charging reduces long-term battery capacity.
When Is Battery Change Required in iPhone?
Not every battery drain means you need replacement. But here’s when you definitely should consider it.
Signs You Need an iPhone Battery Replacement
Battery health below 80%
Phone shutting down unexpectedly
Sudden percentage drops
Device heating abnormally
“Service” message under battery health
Backup lasting less than half a day under normal use
When battery cells degrade, they cannot deliver stable voltage. That’s when you see random shutdowns even at 20–30%.
Replacing the battery restores performance and backup.
What Kind of Phone Batteries Exist?
Most modern smartphones use Lithium-Ion (Li-ion) batteries. However, the quality and internal structure vary.
1. Original Equipment Manufacturer (OEM) Battery
Made to match original specifications in terms of capacity and safety circuits.
2. High-Quality Compatible Battery
Manufactured to meet similar performance standards but not produced by the original brand.
At Instafix, we use tested batteries that meet performance and safety standards to ensure stable voltage output and reliable backup.
“Used Part” vs “Unknown Part” Message in iPhone After Battery Replacement
If you’ve replaced a battery in an iPhone, you might see one of these messages:
“Used Part”
“Unknown Part”
Here’s what that means.
Apple software links the battery to the device’s logic board. When a battery is replaced, the system may display a notification stating that the battery cannot be verified as original.
This does not mean the battery is faulty.
It is a software-level message related to pairing, not performance.
Two Battery Options We Offer
At Instafix, we provide:
A battery that may show a “Used Part” message
A battery that may show an “Unknown Part” message
In both cases:
Performance is stable
Backup improves significantly
Safety parameters are maintained
Can This Message Be Removed?
Yes.
If the customer is comfortable with data wiping, the device can be reset and reconfigured in a way that removes the “Unknown Part” or “Used Part” notification post repair.
We always inform customers beforehand and proceed only with consent.
Transparency comes first
