Apple has reduced the price of battery replacements for the iPhone 6 and newer to $29, down from $79, as part of its apology over a lack of communication about the power management changes it made starting in iOS 10.2.1. The discount is effective immediately and available until the end of 2018.

iPhones come with Li-On (Lithium Ion) Batteries and their performance is measured not how big the Li-On cell is but its capacity that is measured by mAh (milliampere per hour). Although all iPhone models till date have 3.8V battery but Apple has provided different mAh for different models based on their architecture, form factor (size, design) as well as performance parameters. iPhone 6, iPhone 6S, iPhone 7 and iPhone 8 all have more or less ~ 2000 mAh batteries. However, iPhone X, iPhone XR, iPhone 11, have higher mAh battery i.e. ~ 3000 mAh. iPhone 11 Pro Max and iPhone 12 Pro Max have highest mAh, which is almost 3900.
My sony vaio model number VPCEA33EN is showing the battery message as 'Unknown remaining'. It is not getting charged and as soon as i remove the charger the laptop shuts off. I called up the service center and they said that they can replace it but will cost like 150$ or Rs. 8000 Can the battery be repaired ? Please tell me what to do as i can't spend that much amount to buy a new battery.

3) The batteries don't like to sit at 100%. Once it's charged, take it off the charger. Bonus points if you put it right into a tool and turn it on for like 5 seconds. Now it's at like 95% charge, it's much happier, battery is now ready for storage and doesn't need to be touched for a year.

This situation will cause your battery to have a reduced capacity and will lead to premature failure and a loss of performance under load. It will also produce more heat within the battery, which is never a good thing. A BMS is used to help keep a battery in balance, if a BMS fails or is inadequate a pack can become out of balance over time.

iPhone batteries are made from li-on cells. It’s not possible to repair the battery, only replacement.
If a relatively new pack has only one defective cell and a replacement is located, exchanging the affected cell makes sense. With an aged battery, however, it’s best to replace all cells. Mixing new with old causes a cell mismatch that has a short life. In a well-matched battery pack all cells have similar capacities. An anomaly is a chain in which the weakest link determines the performance of the battery(See BU-302: Serial and Parallel Battery Configurations)
That’s exactly what I was thinking. I worked on electronics 25+ years in the military, so I know a thing or two. Those two terminals that the battery uses to make contact with both the charger and tool are no different than the contacts within the battery. So doing this pulse exercise on those exterior contacts will
