Running-cost models, specification explainers and comparisons, built on the same normalised data as our product pages. Every figure is either measured, declared by the manufacturer, or computed from those — and sourced either way.
Match screen size to viewing distance, panel type to room lighting, and resolution to how close you sit. Refresh rate only matters for gaming. Everything else — brand, audio wattage, HDR logos — is secondary. The eight televisions below, ₹13,999 to ₹62,990, show how these trade-offs actually play out.
Android phones sold in India receive between 1 and 7 OS upgrades and between 3 and 7 years of security patches, and the figure is not related to price. A Rs16,999 Samsung Galaxy M35 gets 4 upgrades and 5 years of patches; a Rs17,999 Motorola G85 gets 1 upgrade and 3 years. Google Pixel and recent Samsung flagships lead with 7 years of both. Check the manufacturer commitment before the processor, because it decides how long the phone stays safe to use.
A 20,000 mAh power bank delivers about 13,000 mAh to a phone, which is roughly 3 to 3.5 full charges of a 4,000 mAh phone rather than the 5 the label implies. The rating is measured at the internal cell voltage of 3.7 V, your phone charges at 5 V, and the conversion loses 30 to 35 percent. To estimate real output, multiply the rated capacity by 0.65.
A 2,000 W 25-litre storage geyser used by a family of four costs roughly Rs530 a month at Rs8 per unit, or about 800 kWh a year. Of that, roughly Rs145 a month is standing loss: about 0.6 kWh a day spent reheating stored water that nobody has used. Switching the geyser off at the mains when not needed removes almost all of it, saving around Rs1,750 a year.
Read the power brick, not the product. If it says 100-240 V, a plug adapter is all you need. If it says 120 V only, no adapter will help — an adapter changes the shape of the plug and nothing else, and a 120 V appliance on Indian 230 V mains is destroyed rather than slowed. Separately, check physical fitment and Indian certification, which adapters and transformers cannot fix at all.
No, not within three years. Upgrading from a 3-star (ISEER 3.80) to a 5-star (ISEER 5.10) 1.5-tonne inverter AC saves about 276 kWh a year at BEE’s 1,600-hour test usage — roughly ₹2,208 at ₹8/kWh. Against a ₹17,500 price premium that is a 7.9-year payback. The 5-star unit only pays back inside six years if you run it 2,000 hours a year or more.
Because "RTX 4060" specifies the chip, not the power it is allowed to draw. NVIDIA rates the RTX 4060 Laptop GPU from 35 W to 115 W of total graphics power, plus up to 25 W more via Dynamic Boost. A 115 W laptop and a 140 W laptop carry the same GPU name and the same sticker, but the higher-power machine sustains materially more performance in long sessions.
