- ✅ Capacity close to factory (usually 4300-4400 mAh).
- ❌ 1-3 month warranty (or no warranty).
- ❌ Risk of charging controller mismatch (may warm or slowly charge).
Budgetary analogue (no-name):
- ✅ Lowest price: from 800 ₽).
- ❌ Capacity is often understated (actually 3,500-4000 mAh instead of the stated 4500 mAh).

How do you know if your battery really needs to be replaced?
Before you bring your phone to the service, make sure that the battery is the problem. Here are 5 signs that it is time to change the battery:

- Sudden blackouts. For example, the phone shows 30% charge and then abruptly turns off.
- Overheating when charging: If the body heats up strongly during charging (hotter than usual), this may indicate battery degradation.
- Long-term charging: If the phone used to charge in 1.5 hours, and now it charges in 3-4 hours, the problem is the battery or power controller.
You can also check the status of the battery using special applications:
- 📱 AccuBattery (shows real capacity and wear).
- 📱 AIDA64 (section “Battery» → «Status»).
- 📱 CPU-Z (information on the number of charging cycles).
If the actual battery capacity is below 2500-3,000 mAh (at the initial 4500 mAh), it is definitely time to change it.
