I found a source saying phones need 1 kWh/year, to the closest 10 kWh. That's quite strange. Better source needed? --While False (speak|museum) 04:32, 4 October 2022 (UTC)


An average iPhone has somewhere around 12 Wh of capacity, which at 1 kWh/year would imply only ~23% per day. Anecdotally, that's definitely not right. An IEEE article claims 4 kWh/year, but I don't have access and only see this in the Google snippet. --172.69.134.17 05:37, 4 October 2022 (UTC)

  • What about my S series Samsung?

It has 5000mAh battery, 3,7V voltage, ergo (5 amper * 3,7 volt) = 18,5 watts/hour. It lasts for, roughly, 1 day of heavy use at work (camera, youtube etc., its was my media device) and 2 days of weekend use.

My phone has been in use for 4 years before an upgrade, which gives 366+365+365+365=731+730=1461 day. 1467/7*6 full recharges -- ~1253 recharges. 1253*18,5Wh gives ~18,5kWh*5/4 --- 23,09 kWh; 5,6 kWh per year. 172.70.250.223 07:18, 4 October 2022 (UTC)
