1. Why HiWatch Battery Drains Fast
Many users think their watch is defective, but the truth is:
90% of fast battery drain is caused by software settings.
Common reasons include:
- Screen brightness too high
- Always-on display enabled
- GPS running in background
- Continuous health monitoring
- Bluetooth calling always active
- Too many notifications
- Using live wallpapers
- Old firmware version
- Sleep tracking running all night
- Weather updates every 15 minutes
Understanding these helps you optimize battery effectively.
2. Realistic Battery Expectations
Depends on model & usage:
✔ HiWatch Basic Models
- 3–5 days (normal use)
- ~2 days (heavy use)
✔ HiWatch Pro / T800 / T900 Series
- 2–4 days (normal)
- 1–2 days (heavy)
✔ HiWatch Plus
- Up to 5–7 days (eco mode)
3. How to Check Battery Health
Battery health tells you whether your smartwatch is aging normally.
Steps:
- Go to Settings
- Scroll to Battery
- Check:
- Battery consumption
- Screen usage
- Background apps
- Watch face usage
If your screen usage is over 50%, reduce brightness or turn off Always-On Display.
4. Battery Optimization Settings on the Watch
These internal settings greatly influence battery life.
✔ 1. Reduce Screen Brightness
Settings → Display → Brightness
Recommended:
- Indoors: 20–40%
- Outdoor: 60%
✔ 2. Reduce Screen Timeout
Settings → Display → Screen Timeout → 5–10 sec
✔ 3. Disable Always-On Display (AOD)
AOD is one of the biggest battery killers.
✔ 📸 Display Settings
✔ 4. Turn Off Dynamic Wallpapers
Live wallpapers drain CPU + GPU.
Use a simple static image instead.
✔ 5. Turn Off Vibration for Each Notification
High vibration strength drains battery quickly.
Settings → Vibration → Medium / Low
✔ 6. Use Power Saving Mode (if available)
Some HiWatch models include:
- Power Save Mode
- Ultra Save Mode
This reduces animations, background processes, and sync frequency.
5. Battery Optimization in the HiWatch App
The HiWatch App has many settings affecting battery life.
✔ 1. Reduce Notification Sync
Go to:
HiWatch App → Notifications
Turn off apps you don’t need such as:
- TikTok
- Snapchat
- YouTube
- Facebook Messenger
- Email alerts
Only keep:
✔ WhatsApp
✔ Calls
✔ SMS

✔ 2. Disable 24/7 Heart Rate Monitoring
Continuous tracking = continuous battery drain.
Set to:
- Every 10 minutes
- Manual measurement only (best for battery)
✔ 3. Disable SpO2 Continuous Monitoring
SpO2 consumes a lot of power—use only when needed.
✔ 4. Reduce Weather Update Frequency
Settings → Weather → Update Period
Set to: 1 hour or manual
✔ 5. Disable “Raise to Wake” if battery is critical
This feature triggers the screen hundreds of times per day.
6. Features That Consume the Most Battery
Based on user testing, the top battery killers:
| Feature | Battery Impact |
|---|---|
| Always-on display | 🔥 Massive drain |
| Brightness 100% | 🔥 High |
| Bluetooth Calling | 🔥 High |
| Live wallpapers | 🔥 High |
| GPS tracking | 🔥 High |
| WhatsApp notifications | Medium |
| Raise-to-wake | Medium |
| Weather updates | Medium |
| Step counter | Low |
| Heart rate manual check | Low |
7. What to Disable for Longer Battery Life
If your battery drains too fast, disable the following:
❌ Disable These
- Always-On Display
- Dynamic wallpapers
- Continuous SpO2 tracking
- Continuous stress tracking
- Over 10 app notifications
❌ Reduce These
- Raise to Wake
- Weather updates
- Vibration intensity
- Screen brightness
✔ Battery-Saving Watch Face
Use a dark, simple watch face with no animations.
8. Recommended Power-Saving Configuration (Best Balance)

This is the recommended best battery + full functionality setup:
| Setting | Recommended |
|---|---|
| Brightness | 30–40% |
| Screen timeout | 5 sec |
| AOD | Off |
| Raise to wake | On |
| HR monitoring | 10-minute interval |
| SpO2 | Manual only |
| Notifications | WhatsApp + Calls only |
| Vibration | Medium |
| Weather refresh | 1 hour |
This gives:
- HiWatch: 3–4 days
- HiWatch Pro: 2–3 days
- HiWatch Plus: 5 days
9. Night Mode & Sleep Battery Tips
To reduce overnight drain:
✔ Enable Do Not Disturb
Stops excessive notifications.
✔ Turn brightness to low
Night mode → Auto / Manual
✔ Disable Raise-to-Wake (during sleep)
Prevents screen from lighting unintentionally.
✔ Disable Wi-Fi (if your model has it)
10. Charging Tips to Extend Battery Lifespan
Most users shorten battery lifespan by improper charging.
Follow these rules:
✔ 1. Charge Within 20–80%
Avoid letting battery drop to 0% daily.
✔ 2. Charge slowly
Avoid fast chargers. Use:
- 5V 1A
- 5V 0.5A (best for smartwatch longevity)
✔ 3. Don’t charge overnight
Lithium batteries degrade when overcharged.
✔ 4. Keep charging temperature cool
Heat = battery killer.
11. Common Battery Problems & Fixes
Below are the most frequent issues:
❗ A. Battery drains too fast after update
Fix:
- Restart the watch (very important)
- Wait 24h for system re-indexing
- Reduce brightness
❗ B. Battery drops during standby
Fix:
- Disable “Wake on wrist turn”
- Change to a simple static watch face
❗ C. Battery drains too fast during call
Bluetooth calling consumes 5–10% per 10 minutes.
Use standard Bluetooth mode instead of HD calling.
❗ D. Battery draining with no usage
Possible causes:
- Too many notifications
- Firmware bug
- Faulty watch battery
Try resetting the watch:

- Battery drains from 100% → 0% in 2–3 hours
- Watch shuts down randomly
- Overheating during normal use
- Battery % jumps up or down suddenly
HiWatch uses standard lithium polymer cells, which typically last:
📌 350–500 full cycles (1–2 years)
13. Final Recommendations
To get the longest battery life:
- Use dark, simple watch faces
- Turn off unnecessary background health tracking
- Keep Bluetooth calling off unless needed
- Use official app: https://hiwatch.app/
