@ From Vertu with Love, if you are using the wifi tethering, you may have experienced the bug where the battery drain is high even when you turn off the wifi hotspot.

Only a reboot helps in this case.

It's not clear if the bug has been corrected yet, See TJC.

Lucky you. Mine drains DOWN TO 29-39% each day. I took it off the charger about 90 minutes ago at 100% and it is down to 95% now.

Hey guys, ever tried a BB Z10? from 100% to empty in max 10hrs (normal use) ... so 39% per day is still good (even compared to iPhone, Android, ...)

I remember when I had a Z10. Full charge when I went to bed, completely uncharged when I woke up. I had one app open. That's when I knew I couldn't stick with it much longer, got a Lumia 1020 soon after.

if im on wifi, my battery lasts ages!
for me its similar to you guys.. itll only drain about 20-30% if on wifi all day

but if im on 4G.. battery is gone in about 8-10hrs
3G it lasts a bit longer

Quick reply...

There are many factors.
1. Battery capacity (don't drop battery onto hard surfaces! Li-ion batteries can suffer from that);
2. Connectivity (if you leave WiFi or Cellular or Bluetooth or GPS or FM or something transmitting... and if, for some reason, it has to transmit loudly - for example, cellular tower is not particularly visible indoors, or it is trying to find all the WiFi connections available around it);
3. Apps (or daemons) open, refreshing something every minute, and so on (especially widgets);
4. Memory leaks in long-open apps-or-daemons;
5. Screen-display brightness, as well as keyboard back-light.

Thank you. Best wishes.

oh whuuuut? leaving my app open being idle will use up a lot of battery?

but what if its just my message app or the calender?

pichlo | # 3148 | 2015-01-15, 07:07 | Report

It's spelt calendar

And it depends on the app. Well written apps idle well, with no battery drain. Runaway apps can indeed drain your battery in virtually no time at all.

I'd love to get back to 20-30%. Since the last update my Jolla keeps disabling 3g data and with that disabled I seem to get a phenomenal 8-10%. I'd rather it kept 3g enabled as having to check all the time and toggling flight mode to get it back is becoming tiresome.

You are not alone; I generally get about the same drain rate as you
