These are the symptoms that point at Android battery replacement. Match them against your phone, then book a free diagnosis — we confirm the actual fault before quoting, across every major Android brand.
Capacity has dropped well below the original rating — a new cell restores all-day life.
An aged cell can't deliver peak current, so the phone cuts out even at 20–40%.
A swollen battery is a safety risk — stop using it and get it replaced promptly.
Voltage collapse on a worn cell — it reports full but can't hold it.
Rising internal resistance dissipates energy as heat, often paired with rapid drain.
Why iTweak for Android
Most repair shops treat every Android phone the same way. iTweak understands the nuances — Samsung Knox handling, Google Pixel's Titan M chip diagnostics, OnePlus fastboot protocols, AMOLED vs Super AMOLED screen calibration. ISO 9001:2015 certified workbench, 16+ years in the business, board-level repair for charging ICs and display driver ICs. Custom ROM and bootloader support where needed.
Android repair quality varies wildly between brands and models. The difference isn't just the part — it's the technician's understanding of brand-specific quirks (Samsung Knox, Google's verified boot, OnePlus' OxygenOS diagnostics) and access to board-level schematics.
OEM-grade parts, brand-specific diagnostics, warrantied
Copy-pasted approach across all brands

ESD-protected workstation, OEM-equivalent parts (AMOLED panels with original touch sensitivity, genuine battery cells). Most repairs done in 30–60 minutes. Board-level repairs take a few days. Your data is preserved.
