While some folks (like myself) use long (3m/10ft) cords, most people are stuck with 1m charging cables or less. That's indeed a pain if you use your phone a lot. It's also frustrating to deal with charging cables getting old while your phone's charging port is also getting old. However, Energizer's take on the problem (custom 18000mAh phone) doesn't feel good either: the resulting phone feels too heavy. A hefty brick of a ~18000mAh powerbank itself is already too heavy for many pockets, even outside of "skinny jeans" fashion.

* Oh! By the way, last week, I almost got into a problem. I plugged my phone, went to sleep, woke up without an alarm and assumed it is too early to get out of bed. Then, the street noises made me realize it's actually 9AM already and I am late for work. "So much for XXI century smart devices", I thought.

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)

"Plugging my phone is a pain" as a modern problem

While some folks (like myself) use long (3m/10ft) cords, most people are stuck with 1m charging cables or less. That's indeed a pain if you use your phone a lot. It's also frustrating to deal with charging cables getting old while your phone's charging port is also getting old. However, Energizer's take on the problem (custom 18000mAh phone) doesn't feel good either: the resulting phone feels too heavy. A hefty brick of a ~18000mAh powerbank itself is already too heavy for many pockets, even outside of "skinny jeans" fashion. 162.158.89.248 08:47, 4 October 2022 (UTC)
