4,000 mAh batteries in Lenovo and Acer smartphones

Ever desperate for their phones to stand out, smartphone makers have finally begun focusing on battery life. Lenovo and Acer have announced phones with 4,000mAh batteries - extremely large in comparison to rivals (e.g. the S6 is 2,600 and the iPhone 6 is just 1,810mAh).

The Lenovo A500 and the Acer K80 will only be initially released in India and Chine respectively.

Lenovo says this should allow for up to 35 hours of talk time, and the boss of Acer had this to say:

"The 4,000mAh battery is perfect for frequent travellers as it eliminates concerns regarding power, allowing users to be constantly connected whilst on-the-go without the need to carry a charger on a daily basis."

Comment:

The problem with battery life is only when a phone doesn't last a day, such as is the case with older models of big-brand phones such as the iPhone 4/4s and even the newer 5 and 6 if you use them a lot or have had them a while. My S5 has an okay battery life, though ideally it would be better. If I don't use it for games or too much throughout the day - then it will last. However, there are times when it needs a charge in the evening to keep it going. This is fairly frustrating and so it should be a minimum requirement of phones that they last the day. This introduction of large batteries is a good idea - but just one way of doing it.

I used to carry a spare battery with me on occasions where I wouldn't be able to charge up my phone (an S3 at the time) - something which worked very well, although the back got worn out after a while and this isn't possible to do with iPhones. I know people who car battery packs around for the same purpose - this isn't the worst idea but when we have such good and advanced technology in our pockets, do we really need to carry a chunky pack just to keep it running? Hopefully we'll see the introduction of fast-charging technology soon - there are companies working on batteries that can be charged in just a few minutes or even seconds.
