iQOO 15R battery health dropped to 99% after 105 cycles — is this normal? Looking for tips

I purchased my iQOO 15R on July 5 and I'm currently on the August software update.

My battery health has now dropped to 99% after 105 cycles. I know 99% isn't necessarily bad, but I want to understand how iQOO calculates battery health and whether my usage is affecting it.

My charging habits:

- I usually charge only up to around 70%.

- Sometimes, before a long gaming session, I charge to 90%.

- During heavy gaming, the battery can sometimes go down to 5–6% before I recharge.

- I use the phone for gaming quite a lot.

- Battery drain is inconsistent: sometimes it drains quickly during gaming, while other times the drain seems much better under similar usage.

I also want to know whether bypass charging is safe to use regularly for long gaming sessions. Can it cause any motherboard or other hardware issues?

For people using an iQOO device:

1. Is 99% health at 105 cycles normal?

2. Does iQOO's battery-health percentage depend mainly on cycle count, or are other factors involved?

3. Is it bad to occasionally let the battery reach 5–6%?

4. Should I continue charging to 70%, or is 80–90% okay?

5. Does bypass charging actually help with battery health during gaming?

6. Why does battery drain sometimes vary so much between gaming sessions?

I'd appreciate advice from people who have been using iQOO phones for a long time.

Hey everyone, I’ve had my Lenovo laptop for about 4 years now and recently checked the battery health in Lenovo Vantage.

• Original design capacity: 45 Wh
• Full charge capacity: 39.84 Wh
• Battery health: 88%
• Charge cycles: 88
• Battery temperature: 32°C

Lenovo Vantage shows the battery condition as “Good.”

Is 88% health after 4 years considered good? I’m a little surprised that it has only gone down by around 12% after this much time. Just curious how this compares with other people’s laptops and whether I should expect the battery to degrade more quickly from here.

Anyone else experiencing heating and battery drain issues? I’m currently facing a noticeable battery drain issue and did the issue get fixed after this update ?
