Collect battery life improvement tips for knowledge base
Locus developers spend a lot of effort to save every milliamp hour of power. We did reach optimization levels where complex solutions will only safe less than 0.1% batter life per hour.
But what is happen on user devices? Most of us don't know the tricks to save battery life and we waste up to 100 times more batter life then new locus optimisations will gain us.
We should collect tipps for better battery life to appreciate all the optimization effort of locus developers. Otherwise our careless handling of battery power will disrespect the optimisation effort.
There are even some important locus features to help improving batter life and most of us don't know about them.
I will start with the following tipps:
- benchmark battery lifetime with locus on custom roms. I got hugh margins across android versions. With full LCD power I got track recording times from 4 hours to 8,5 hours. Up to 100% Battery life improvement just by using a different rom! Unfortunately the older unsecure roms perform best
- Try to avoid using SD cards, they are rated around 200mW/h and sometimes they don’t get into a proper idle state (I didn’t prove how much % batter life gain could be expected here)
- Keep plane mode on and use offline routing, because some roms have problems to enter a proper mobile network idle state
- Disable wlan, nfc, bluetooth during navigation because you only rarely need them on tour
- try to reduce screen on time by using locus screen activation/deactivation features
- use sound alert or voice navigation to reduce screen on time even more
- Bt gps devices produce better signals with same amount of current like your internal gps because the have larger antennas then your phone. (BT communication signals take way less current then your phone gps and if you would, you can avoid locus track recording and track with an gps logger, locus can disable unused BT connection during screen off time to save even more power)
- Keep your system clean especially if you have an old android version. Older systems have better battery lifetime but worse background activity management. Which means a phone with many apps will lose the benefit of a small, old, but very efficient operating system. Maybe you should consider using a 2nd phone setup for offline usage without any installed apps. An old android system isn’t recommend anyway for online usage, which means it will make even more sense to setup a navigation only phone if you want to achieve up to 100% batterylife improvement by doubling your screen on time. By the way if you are alone, In case of an emergency it make sense to have 2nd phone anyway because you may break your exposed navigation phone during an accident.
Does anyone have any other tipps to add?
