It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Highscreen Blast — 3.7V Li-ion Replacement Battery

This is a 3.7V, 1800mAh Li-ion battery for the Highscreen Blast smartphone. It replaces the original cell when the phone no longer holds charge, shuts down unexpectedly, or fails to power on. Capacity is 6.66Wh, matching the original specification.

  • Highscreen Blast fit: The Blast uses a removable Li-ion cell on a 3.7V rail with a standard three-contact connector — voltage, ground, and thermistor. This replacement matches that pinout and voltage so the charge IC communicates correctly with the new cell.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench. The BMS held cutoff at the correct low-voltage threshold and accepted a full charge without triggering thermal protection on the charge IC.
  • Fuel gauge recalibration on first use: After fitting this battery, disable fast charging and run one complete discharge-to-charge cycle at standard speed. This lets the fuel gauge IC map its coulomb counter to the new cell's actual discharge curve before high-current charging starts.

Sudden shutdown at 20–30% on the Highscreen Blast

When the Blast shuts down with charge still showing on screen, the fuel gauge IC is reading percentage against the old cell's discharge curve. The new cell has a steeper voltage drop under modem and screen load at lower state-of-charge. The phone's charge controller interprets that voltage drop as a hard cutoff, not a percentage reading. One full slow discharge cycle — down to automatic shutdown, then a full charge — lets the coulomb counter reset its baseline against the new cell.

Percentage jumping or reading 0% immediately after installation

A new cell installed after deep storage can sit below the fuel gauge IC's calibration window, causing the OS to report 0% or skip erratically between values. Connect the Blast to a charger and leave it for at least 15 minutes before attempting to power on — the charge IC needs to push the cell above roughly 3.0V before the fuel gauge can lock onto a stable reading. If the phone still reports 0% after 30 minutes on charge, disconnect and reconnect the battery to reset the BMS handshake. After that, run one full charge to 100% without interruption.

Frequently Asked Questions

My Highscreen Blast shuts off mid-call even though the battery still shows 25% — why?

This is a voltage cliff issue, not a fuel gauge misread. Under modem transmit load, the new cell's voltage drops sharply at low state-of-charge, and the phone's charge controller reads that as a hard undervoltage cutoff before the percentage counter catches up. The fix is one full slow discharge cycle — let the phone run down to automatic shutdown, then charge to 100% without interruption. After that single cycle, the coulomb counter recalibrates its curve to the new cell and the shutdowns stop.

The Highscreen Blast won't power on at all after the new battery sat in the phone for a few weeks unused — what's happened?

Li-ion cells self-discharge in storage, and if the Blast sat long enough for the cell to drop below approximately 2.5V, the BMS enters a lockout state to prevent further discharge damage. The phone will not respond to the power button in this state. Connect it to a charger and wait — the charge IC trickle-charges the cell back above the BMS recovery threshold before it allows normal charging to resume. Leave it on charge for 20–30 minutes without pressing any buttons, then try powering on.

The battery percentage on my Blast is jumping around — it reads 60%, then drops to 40%, then bounces back up — is the battery defective?

The battery itself is fine. The Blast's fuel gauge IC stores a learned discharge curve from the old cell, and the new cell has a different impedance profile. Until the IC recalibrates, it interpolates percentage incorrectly and the reading jumps. Run one complete discharge-to-shutdown followed by an uninterrupted charge to 100% — this forces the coulomb counter to rebuild its model against the actual new cell curve. After one full cycle the percentage reading stabilises.
