Battery draining fast, phone switching off at 30%, swelling or heating? We fit original-grade batteries for iPhone, Samsung, Vivo, Oppo, Realme, OnePlus and Redmi in 20–40 minutes with warranty.
मोबाइल बैटरी बदलना — कोटा में, उसी दिन, आपके सामने।
Every lithium battery wears out. After 500–800 charge cycles (about 1.5–2.5 years for most users) you notice the classic signs: the phone dies at 20–40%, needs charging twice a day, gets hot, or the back panel starts to lift because the cell has swollen. A new battery makes the phone feel new again — for a fraction of the price of a new phone.
At Prince Mobile we replace batteries for all brands with original-grade, tested cells. iPhone batteries are fitted to show 100% Battery Health, and on supported Android models the battery calibration is reset so the percentage reads correctly. Most jobs take 20–40 minutes while you wait.
Signs your battery needs replacing
Battery drops quickly from 100% to 60% and then dies suddenly around 20–40%.
iPhone Battery Health below 80%, or a "Service" / "Important Battery Message".
Phone shuts down in the cold, when the camera opens, or when the signal is weak.
Swelling: screen lifting, back cover bulging, phone rocking on a table — stop charging and bring it in today; a swollen battery is a fire risk.
Phone only works while plugged in, or charging takes much longer than before.
Why a cheap battery is expensive
Low-grade cells advertise big mAh numbers but deliver 60–70% of the capacity, drain fast within months and swell early. We source batteries with proper protection circuits, real capacity and consistent quality — and we back them with a warranty. If the phone's problem is actually the charging IC or a software issue, we tell you instead of selling a battery you do not need.
What happens during the replacement
Free check: battery health, charging current and power-IC behaviour.
Phone opened in front of you; old adhesive strips removed safely (swollen cells handled with extra care).
New battery fitted with fresh adhesive; back panel or display re-sealed with new adhesive on water-resistant phones.
Charging and health check with you; old battery handed back or disposed of safely — your choice.
Prices are indicative ranges (2026) and depend on the exact model and part quality (original / OG / compatible). The exact price is confirmed after a free check-up, before any work starts. Prices include labour and GST-free repair service.

Battery Replacement — frequently asked questions
How much does phone battery replacement cost in Kota?
Android batteries are usually ₹699–₹1,600, flagship Android ₹1,400–₹3,200, and iPhone batteries ₹1,200–₹4,800 depending on the model. Labour is included; we confirm the exact price after a free check.
Will the iPhone show "Unknown Part" or 100% health?
We fit batteries that report health correctly. Depending on the iPhone model and part type, iOS may show a genuine-part notice — we explain the options for your exact model before you decide.
How long does the new battery last?
A good replacement battery gives 1.5–3 years of normal use. Avoid cheap fast chargers, extreme heat and running the phone to 0% regularly.
My battery is swollen. Is it safe to keep using the phone?
No. Stop charging it, do not press the screen, and bring it in as soon as possible. A swollen battery can damage the display and is a fire risk.
