Talk:Battery charger

Mobile phone charger - pre 2010?
"'Another fact about phones is that if your phone dates from 2010 or earlier you will have a better and greater chance of over-charging your phone unlike the newer generation phones like the iPhone 5 or the Samsung Galaxy Note have a charging program on it that help your phone when it is in its charging stage. Unlike newer phones when it reaches a certain level on your battery it will stop trying to insert more power unlike phones from 2010 or earlier they will continuously shove more and more power not stopping until you unplug your phone.'" What is this 'fact' based on? It seems to me that this entirely depends on the phone manufacturer. Even if it is true, this needs to be rephrased and requires a reference.

Off topic
It looks like some content that talks about USB and related power supplies got incorrectly merged into this article (e.g. "Power bank"). The confusion is because the term "charger" is sometimes also used for power supplies for battery-powered mobile devices, but they are distinct concepts. A USB power supply is not a "battery charger" as defined in this article's lead, as it does not force current through a secondary cell, but rather supplies a voltage that the downstream device can use (for battery charging, powering itself, or any other use). The indicated sections should be moved to the appropriate articles. 73.202.12.249 (talk) 23:49, 21 July 2019 (UTC)
 * We should include them and discuss them here, even though this is a real issue and we will need to be careful about wording.
 * These 'phone chargers' used to be battery chargers, but are now standardised and simplified as mere 5V USB power supplies. However phone batteries still need to be charged. There are still phone chargers doing this (they're embedded within e or power bank). Our readers will still be turning up at this article, looking for an explanation of how phones are charged, and how this device (whatever it is) is used for that purpose. Likewise when power banks are used for this, rather than mains adapters. Andy Dingley (talk) 00:09, 22 July 2019 (UTC)
 * I removed a lot of the cruft. It read like a guide to buying a phone charger, with poorly written lists on specifications. Didn't seem relevant to this article. drt1245 (talk) 03:24, 27 May 2020 (UTC)


 * Hi,
 * there is a "citation needed" notification in the article's "Power bank" section
 * on the statement "The power bank includes a control circuit that both regulates
 * charging of the battery and converts the battery voltage to 5.0 volts for the
 * USB port."
 * The corresponding photo of an opened Power bank taken by Alexis Jazz in November
 * 2015,
 * https://upload.wikimedia.org/wikipedia/commons/c/c8/Quintezz_powerbank%2C_opened.png
 * shows some electronic components inside the device, besides the Li-Ion battery
 * itself. Their presence seem to confirm the mentioned statement.
 * It wasn't Alexis who made it, and I don't know how to find out the text's author
 * easily. However, I wonder whether the Wikipedia permits to mention "personal
 * observations" in particular cases, e.g. "as confirmed by own measurement on
 * November 23, 2015 (USB outlet provides 5.1 Volts while the battery's current
 * is only 3.7 Volts)".
 * I am glad to learn that Power banks do so (I don't mind about the missing
 * citation) - by chance, my Power bank model is exactly the same as Alexis' one,
 * just with a black instead of a pink case.

Powerbank
Should powerbank really redirect here and not to Rechargeable battery? --95.24.71.132 (talk) 20:44, 2 August 2023 (UTC)
