How to know it's this
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.
Won't last half a day
Capacity has dropped well below the original rating — a new cell restores all-day life.
Shuts down with charge remaining
An aged cell can't deliver peak current, so the phone cuts out even at 20–40%.
Swelling or a lifting back/screen
A swollen battery is a safety risk — stop using it and get it replaced promptly.
Charges to 100% then drops fast
Voltage collapse on a worn cell — it reports full but can't hold it.
Hot during normal use
Rising internal resistance dissipates energy as heat, often paired with rapid drain.
Why iTweak for Android
Multi-brand Android expertise, not a one-size-fits-all approach.
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.
- 16+ years Android repair experience
- ISO 9001:2015 certified
- AMOLED/Super AMOLED screen specialists
- Board-level charging IC & display IC repair
What iTweak fits — across every Android repair
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.

“Samsung service centre quoted ₹18,000 for the AMOLED screen. iTweak did it for ₹9,500 in 45 minutes at my office. Touch sensitivity is perfect — can't tell it's a replacement.”
Pradeep K.Samsung Galaxy S21 · Bangalore“Pixel battery draining in 3 hours. iTweak's tech came to my home, replaced the battery, ran Google's diagnostics to confirm it's genuine. Working like new again.”
Meera D.Google Pixel 6 · Mumbai“OnePlus wouldn't charge, thought it was the motherboard. iTweak diagnosed it as a loose charging port flex in 10 minutes. Fixed for ₹1,800. Impressed by the brand knowledge.”
Aditya R.OnePlus 9 Pro · Chennai“Dropped my Note 20 in the pool. iTweak's board-level team recovered it — ultrasonic cleaning, replaced the charging IC. All my photos safe. Thought I'd lost everything.”
