The P Smart 2019 battery specs
The P Smart 2019 uses a 3,400 mAh cell, and the battery health screen in the Huawei settings gives the first signal. Battery reporting and health indicators vary by device, software version and replacement part. Confirm the region variant before ordering, because the phone was sold under different names in some markets with different connectors.
| Specification | Value |
|---|---|
| Battery | 3,400 mAh |
| Display | LCD |
| Opening | From the rear |
Confirm the model number before ordering, because the P Smart 2019 cell is not shared with the P Smart 2020.
The P Smart 2019 uses a 3,400 mAh cell, and the region variant decides the connector. Original cells report health most accurately.
Signs the P Smart 2019 battery needs replacing
Replace the battery when the health reading drops, the phone shuts down above 20 percent, or the battery swells. Rapid drain and random shutdowns are the everyday signs of an ageing cell.
The physical warning signs matter most: a lifting back cover or a bulging display means a swollen battery, which should be handled carefully and replaced immediately.
P Smart 2019 battery replacement differences
The P Smart 2019 is a budget Huawei with a simple rear-shell opening.
The P Smart 2019 was sold under different names in some markets, so the region confirmation comes first and the connectors can differ. The rear shell opens with a standard sequence, and the battery sits inside with the flexes grouped by position.
The display flexes must be protected while the phone is open.
The Huawei battery guide covers the variant trap across the range; this page focuses on the P Smart 2019 specifics.
Tools you need for a P Smart 2019 battery replacement
You need a standard phone opening kit: Phillips drivers, suction cup, picks, tweezers, a heat source, adhesive and a magnetic mat. The full list is on the Digi4u tools page.
The P Smart 2019 needs nothing special. A heating pad helps release the adhesive, and a magnetic mat keeps the small screws organised.
How do you replace a P Smart 2019 battery?
Power off the phone and remove the SIM tray, then open the phone from the rear according to the service pattern. Disconnect the battery first, then release the old cell with the tabs or gentle heat.
Fit the new battery, reconnect everything, reconnect the battery last, and test before resealing. Use fresh adhesive and apply even pressure around the edges.
Post-repair testing checklist
Test the battery health reading, charging speed, the display, the front camera, the earpiece, the proximity sensor and the microphones. Confirm the phone charges to 100 percent and holds the charge.
Run the full test while the phone is open. If the health reading does not update, the battery is not reporting correctly or the connector is loose.
P Smart 2019 charging and port notes
The P Smart 2019 charges at the standard 10 W rate through a micro-USB port and has no wireless charging or fast-charge support, so a full charge is slower than on newer Huawei models – explain this to customers who expect modern speeds.
Huawei’s battery settings show usage but not a precise health percentage on this model, so the replacement decision relies on shutdown behaviour and a charging log. The phone was also sold as the P Smart+ 2019 in some markets, which is why the region check comes first.
The rear shell is plastic, so it needs less heat than glass-backed phones and lifts cleanly with a suction cup and picks. The battery connector sits on the lower edge of the board, and the flexes should be unclipped before the cell is lifted.

Fast drain is usually a sign of an ageing cell, but check background apps and mobile signal before blaming the battery.
