I always had to carry spare batteries for my Symbian devices, no way did they last a couple of days under regular use. Same with my Sony Ericsson J2ME phones. Running stuff like IRC, streaming radio, bluetooth headphones, really sucked down the battery.

My very last one, Nokia 6120 classic did last a couple of days.

> The battery life of Nokia 6120 is impressive. To give you an example, a daily average of 5 minutes of calls and 20 SMS requires charging every four to five days. More demanding jobs, including active internet browsing in UMTS, will surely reduce durability to 2-3 days, but even so the phone does great. Charging takes about 2.5 hours.

Try to do this with most mid range Android devices.

Indeed, and that's why a lot of people in China now buy a secondary "dumbphone" in addition to smartphone.

I believe we will end with 6.8~7.2 inch smartphones going mainstream in the West too soon.

People will be carrying their aircraft carrier sized smartphones in bags, or pouches, while using a dumbphone for talk.

I literally laughed out loud at that.

Modern smartphones have fantastic battery life if you switch off data and use them like dumbphones. When I travel sometimes I leave my home SIM with data off in an old iPhone and it easily lasts a week.

Most people still follow such patterns, not everyone is glued on their phone 24x7.

I am yet to own an Android device that lasts more than 3 days.

Do you literally switch off data, or just not use it? All those background connections for push notifications, etc take a huge toll.

My iPhone 11 Pro Max lasts 2 days with decently heavy use if I'm not going totally crazy on it, I haven't used Android in ages though.

Data is only switched on when required, we are far away from flatrates over here.

In fairness, my Samsung S7 will happily last 2-3 days on a charge if I put it in "ultra power saving mode" (and this is a 3 year old device). And this still allows me to make calls/texts, use WhatsApp, the camera, and browse the internet. The Nokia 6120 presumably couldn't ever do much more than that.
