Battery draining faster after 6 months
Hey everyone,
I’m using a OnePlus Nord CE5 (around 6 months old) and I’ve noticed my battery backup has gotten worse recently, even though my usage hasn’t really changed.
What’s happening:
Earlier:
100% used to last ~30–40 minutes
After that, 99% would last around ~10 minutes
Now:
100% only lasts ~15–20 minutes
99% lasts around 6–7 minutes
Also during usage:
Earlier: ~10–12% battery lasted around 2 hours
Now: ~15–16% drains in similar/light usage
My daily usage (important):
I travel by bus for ~2 hours daily
Phone is used for around 1 hour 40 mins during that time
Sometimes Instagram (reels etc.)
Mostly music apps
Same route, same routine as before
Extra detail:
It’s currently very hot where I live (~45°C outside)
My phone heats up during travel/use in these conditions
But here’s the weird part:
Overnight drain is only 3–4%
Phone goes into deep sleep properly
No overheating in normal indoor conditions
So idle drain seems completely normal, which makes me think battery health is still fine.
Possible thing I did differently:
For the past 10–15 days, I wasn’t charging to 100% regularly (mostly between 20–80/85%)
Before that, I usually kept it between 90–100%
Problem: I can’t check battery health in settings, so I don’t know if it’s degraded or just a software/usage issue.
Question:
Is this normal after ~6 months?
Could this be calibration/network/app + heat related instead of battery wear?
Anyone else facing similar issues on OnePlus devices?
Would really appreciate any help or similar experiences 🙏
